To the 62 | extent this Public License may be interpreted as a contract, You are 63 | granted the Licensed Rights in consideration of Your acceptance of 64 | these terms and conditions, and the Licensor grants You such rights in 65 | consideration of benefits the Licensor receives from making the 66 | Licensed Material available under these terms and conditions. 67 | 68 | 69 | Section 1 -- Definitions. 70 | 71 | a. Adapted Material means material subject to Copyright and Similar 72 | Rights that is derived from or based upon the Licensed Material 73 | and in which the Licensed Material is translated, altered, 74 | arranged, transformed, or otherwise modified in a manner requiring 75 | permission under the Copyright and Similar Rights held by the 76 | Licensor.

Effective Technological Measures means those measures that, in the 94 | absence of proper authority, may not be circumvented under laws 95 | fulfilling obligations under Article 11 of the WIPO Copyright 96 | Treaty adopted on December 20, 1996, and/or similar international 97 | agreements. 98 | 99 | e. Exceptions and Limitations means fair use, fair dealing, and/or 100 | any other exception or limitation to Copyright and Similar Rights 101 | that applies to Your use of the Licensed Material. 102 | 103 | f.

Subject to the terms and conditions of this Public License, 138 | the Licensor hereby grants You a worldwide, royalty-free, 139 | non-sublicensable, non-exclusive, irrevocable license to 140 | exercise the Licensed Rights in the Licensed Material to: 141 | 142 | a. reproduce and Share the Licensed Material, in whole or 143 | in part; and 144 | 145 | b. produce, reproduce, and Share Adapted Material. 146 | 147 | 2. Exceptions and Limitations. For the avoidance of doubt, where 148 | Exceptions and Limitations apply to Your use, this Public 149 | License does not apply, and You do not need to comply with 150 | its terms and conditions. 151 | 152 | 3. Term. The term of this Public License is specified in Section 153 | 6(a). 154 | 155 | 4. Media and formats; technical modifications allowed. The 156 | Licensor authorizes You to exercise the Licensed Rights in 157 | all media and formats whether now known or hereafter created, 158 | and to make technical modifications necessary to do so.

For purposes of this Public License, 164 | simply making modifications authorized by this Section 2(a) 165 | (4) never produces Adapted Material. 166 | 167 | 5. Downstream recipients. 168 | 169 | a. Offer from the Licensor -- Licensed Material. Every 170 | recipient of the Licensed Material automatically 171 | receives an offer from the Licensor to exercise the 172 | Licensed Rights under the terms and conditions of this 173 | Public License. 174 | 175 | b. No downstream restrictions. You may not offer or impose 176 | any additional or different terms or conditions on, or 177 | apply any Effective Technological Measures to, the 178 | Licensed Material if doing so restricts exercise of the 179 | Licensed Rights by any recipient of the Licensed 180 | Material. 181 | 182 | 6. No endorsement. Nothing in this Public License constitutes or 183 | may be construed as permission to assert or imply that You 184 | are, or that Your use of the Licensed Material is, connected 185 | with, or sponsored, endorsed, or granted official status by, 186 | the Licensor or others designated to receive attribution as 187 | provided in Section 3(a)(1)(A)(i). 188 | 189 | b. Other rights. 190 | 191 | 1. Moral rights, such as the right of integrity, are not 192 | licensed under this Public License, nor are publicity, 193 | privacy, and/or other similar personality rights; however, to 194 | the extent possible, the Licensor waives and/or agrees not to 195 | assert any such rights held by the Licensor to the limited 196 | extent necessary to allow You to exercise the Licensed 197 | Rights, but not otherwise. 198 | 199 | 2. Patent and trademark rights are not licensed under this 200 | Public License. 201 | 202 | 3. To the extent possible, the Licensor waives any right to 203 | collect royalties from You for the exercise of the Licensed 204 | Rights, whether directly or through a collecting society 205 | under any voluntary or waivable statutory or compulsory 206 | licensing scheme. In all other cases the Licensor expressly 207 | reserves any right to collect such royalties. 208 | 209 | 210 | Section 3 -- License Conditions. 211 | 212 | Your exercise of the Licensed Rights is expressly made subject to the 213 | following conditions. 214 | 215 | a. Attribution. 216 | 217 | 1. If You Share the Licensed Material (including in modified 218 | form), You must: 219 | 220 | a. retain the following if it is supplied by the Licensor 221 | with the Licensed Material: 222 | 223 | i. identification of the creator(s) of the Licensed 224 | Material and any others designated to receive 225 | attribution, in any reasonable manner requested by 226 | the Licensor (including by pseudonym if 227 | designated); 228 | 229 | ii. a copyright notice; 230 | 231 | iii. a notice that refers to this Public License; 232 | 233 | iv. a notice that refers to the disclaimer of 234 | warranties; 235 | 236 | v. a URI or hyperlink to the Licensed Material to the 237 | extent reasonably practicable; 238 | 239 | b. indicate if You modified the Licensed Material and 240 | retain an indication of any previous modifications; and 241 | 242 | c. indicate the Licensed Material is licensed under this 243 | Public License, and include the text of, or the URI or 244 | hyperlink to, this Public License. 245 | 246 | 2. You may satisfy the conditions in Section 3(a)(1) in any 247 | reasonable manner based on the medium, means, and context in 248 | which You Share the Licensed Material. For example, it may be 249 | reasonable to satisfy the conditions by providing a URI or 250 | hyperlink to a resource that includes the required 251 | information. 252 | 253 | 3. If requested by the Licensor, You must remove any of the 254 | information required by Section 3(a)(1)(A) to the extent 255 | reasonably practicable. 256 | 257 | 4. If You Share Adapted Material You produce, the Adapter's 258 | License You apply must not prevent recipients of the Adapted 259 | Material from complying with this Public License. 260 | 261 | 262 | Section 4 -- Sui Generis Database Rights. 263 | 264 | Where the Licensed Rights include Sui Generis Database Rights that 265 | apply to Your use of the Licensed Material: 266 | 267 | a. for the avoidance of doubt, Section 2(a)(1) grants You the right 268 | to extract, reuse, reproduce, and Share all or a substantial 269 | portion of the contents of the database; 270 | 271 | b. if You include all or a substantial portion of the database 272 | contents in a database in which You have Sui Generis Database 273 | Rights, then the database in which You have Sui Generis Database 274 | Rights (but not its individual contents) is Adapted Material; and 275 | 276 | c. You must comply with the conditions in Section 3(a) if You Share 277 | all or a substantial portion of the contents of the database. 278 | 279 | For the avoidance of doubt, this Section 4 supplements and does not 280 | replace Your obligations under this Public License where the Licensed 281 | Rights include other Copyright and Similar Rights. 282 | 283 | 284 | Section 5 -- Disclaimer of Warranties and Limitation of Liability. 285 | 286 | a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE 287 | EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS 288 | AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF 289 | ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS, 290 | IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION, 291 | WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR 292 | PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS, 293 | ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT 294 | KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT 295 | ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU. 296 | 297 | b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE 298 | TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION, 299 | NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT, 300 | INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES, 301 | COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR 302 | USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN 303 | ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR 304 | DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR 305 | IN PART, THIS LIMITATION MAY NOT APPLY TO YOU. 306 | 307 | c. The disclaimer of warranties and limitation of liability provided 308 | above shall be interpreted in a manner that, to the extent 309 | possible, most closely approximates an absolute disclaimer and 310 | waiver of all liability. 311 | 312 | 313 | Section 6 -- Term and Termination. 314 | 315 | a. This Public License applies for the term of the Copyright and 316 | Similar Rights licensed here. However, if You fail to comply with 317 | this Public License, then Your rights under this Public License 318 | terminate automatically. 319 | 320 | b. Where Your right to use the Licensed Material has terminated under 321 | Section 6(a), it reinstates: 322 | 323 | 1. automatically as of the date the violation is cured, provided 324 | it is cured within 30 days of Your discovery of the 325 | violation; or 326 | 327 | 2. upon express reinstatement by the Licensor. 328 | 329 | For the avoidance of doubt, this Section 6(b) does not affect any 330 | right the Licensor may have to seek remedies for Your violations 331 | of this Public License. 332 | 333 | c. For the avoidance of doubt, the Licensor may also offer the 334 | Licensed Material under separate terms or conditions or stop 335 | distributing the Licensed Material at any time; however, doing so 336 | will not terminate this Public License. 337 | 338 | d. Sections 1, 5, 6, 7, and 8 survive termination of this Public 339 | License. 340 | 341 | 342 | Section 7 -- Other Terms and Conditions. 343 | 344 | a. The Licensor shall not be bound by any additional or different 345 | terms or conditions communicated by You unless expressly agreed. 346 | 347 | b. Any arrangements, understandings, or agreements regarding the 348 | Licensed Material not stated herein are separate from and 349 | independent of the terms and conditions of this Public License. 350 | 351 | 352 | Section 8 -- Interpretation. 353 | 354 | a. For the avoidance of doubt, this Public License does not, and 355 | shall not be interpreted to, reduce, limit, restrict, or impose 356 | conditions on any use of the Licensed Material that could lawfully 357 | be made without permission under this Public License. 358 | 359 | b. To the extent possible, if any provision of this Public License is 360 | deemed unenforceable, it shall be automatically reformed to the 361 | minimum extent necessary to make it enforceable. If the provision 362 | cannot be reformed, it shall be severed from this Public License 363 | without affecting the enforceability of the remaining terms and 364 | conditions. 365 | 366 | c. No term or condition of this Public License will be waived and no 367 | failure to comply consented to unless expressly agreed to by the 368 | Licensor. 369 | 370 | d.

First create a static website hosted in Amazon using S3. You 12 | can look at [the 13 | tutorial](http://docs.aws.amazon.com/AmazonS3/latest/dev/website-hosting-custom-domain-walkthrough.html) 14 | to get started with Amazon Web Services (AWS) and S3 in particular. 15 | 16 | Your website should serve a file called `grading.html`. Assuming your domain is `http://ec2-yourdomain-someip.com/`, 17 | the url `http://ec2-yourdomain-someip.com/grading.html` should be available. The file should only contain your 18 | netid ONLY, no html tags whatsoever. 19 | 20 | Checkout [this](https://typtop.info/grading.html) for an example. 21 | 22 | 23 | 2. Add your name, netid, and the url for your `grading.html` page to the course Github repo. Do this by editing the page 24 | README.md and submitting a pull request. Add your name in the appropriate place (please keep names in alpha order 25 | by last name) and using this formatting exactly: 26 | 27 | ```text 28 | [Your Name](people/your-name.md) - yn444 - [https://ec2-yourdomain-someip.com/grading.html](https://ec2-yourdomain-someip.com/grading.html) 29 | ``` 30 | 31 | Make sure the names are in alphabetical order. (It's a good exercise to get conflict and resolving it.) 32 | 33 | This is the [grading script](grade_a1.sh) that will be used to grade the assignment. You can run it yourself to verify you will receive credit for the assignment: 34 | 35 | ```bash 36 | $ bash grade_a1.sh 37 | ``` 38 | ### Things that may go wrong. 39 | * Your pull request might conflict with others. So, either make sure your branch is uptodate 40 | with [`CT-CS5356-Fall2017/cs5356`](https://github.com/CT-CS5356-Fall2017/cs5356/), or fix the conflict on GitHub. 41 | Please don't delete changes made by someone else in the process of merging, or your pull request (PR) will surely 42 | be rejected. 43 | 44 | * The script is returning error while your url in browser runs fine.

The goal of this assignment 7 | is to familiarize you with REST architecture, the CircleCI Continuous Integration tool, and 8 | the mechanism by which one can deploy software to the cloud. 9 | 10 | We will not worry about session management and access control---an user can read / write any receipt. 11 | We will not worry about setting up an external database - we will use H2 (which 12 | supports the MySQL SQL Dialect). 13 | 14 | To complete the assignment you must complete the following: 15 | 1. Configure CircleCI to run on the `master` branch in your repo 16 | 2. Add a CircleCI build-status badge to README.md 17 | 3. Build a RESTful API that supports operations on `receipts` and `tags` 18 | 4. Deploy the API to AWS 19 | 5. Submit 20 | 21 | ## 1. Configuring CircleCI 22 | [CircleCI](http://circleci.com/) is a cloud-based tool for building software. CircleCI seamlessly integrates with 23 | GitHub to detect when a change is made, at which point CircleCI will execute a series of build-steps that are 24 | defined in the file `.circleci/config.yml` which must be added to your GitHub repository. 25 | 26 | When you initially log into CircleCI you should see a [Dashboard](https://circleci.com/dashboard) showing recent builds. 27 | A **Projects** menu-option on the left-hand side will help you configure your repo. Choose 28 | **Add Project**, select the repository you want to setup by clicking **Setup Project** next to your repository name, and 29 | finally select the OS (linux), Platform (2.0) and Language (Gradle/Java). 30 | 31 | Circle will reward your efforts here by preparing a sample `config.yml` along with detailed instructions you should 32 | follow carefully to get your CI system setup. The sample `config.yml` will work without modification, however you 33 | should not be afraid to dive into the excellent [CircleCI Docs](https://circleci.com/docs/2.0/) to add custom 34 | build steps such as building a docker-image. 35 | 36 | Once CircleCI is setup, every time you push changes to GitHub CircleCI will detect the change and will follow the steps 37 | defined in `config.yml`. By should always include *checking out the new code* and *running the tests*. `build.gradle` 38 | in the `skeleton` repo is already setup to run any tests that are annotated with `@Test`. You can check this yourself 39 | by running the `test` target e.g. `./gradlew test`. 40 | 41 | ## 2. Setting up a CircleCI build status badge 42 | **Important** - adding your build status badge to `README.md` in the class GitHub is the *only* way to get credit for 43 | setting up CircleCI. You can get the code for *your badge* by copying it from the **Status Badges** section of the 44 | **Settings** page for your project in CircleCI. 45 | 46 | To get credit for the assignment you must add the badge as a suffix to your line in the **Students** section 47 | of the `README.md`, you must write at least one non-trivial test, and CircleCI must run the test + pass. 48 | 49 | A working test is available in the `skeleton` project at `src/test/java/api/CreateReceiptRequestTest.java` 50 | 51 | ## 3. Build a RESTful API 52 | The API we are building is relatively simple, and only supports operations on two 53 | resources: `receipts` and `tags`. The basic idea is that one should be able to create new 54 | receipts, *categorize* them by using user-defined *tags*, and retrieve receipts *by-tag*. 55 | 56 | Endpoints required to support this functionality with inputs and outputs are summarized below. All endpoints must 57 | return `200/OK` if the operation completed successfully. 58 | 59 | ### POST /receipts 60 | **Effect:** Create a new receipt. Every receipt should have an `UNSIGNED INT` primary key which 61 | is returned by this endpoint. No duplicate detection or uniqueness constraints are required. New 62 | receipts are un-tagged. 63 | 64 | **Request Body:** 65 | ```javascript 66 | { 67 | "merchant": "foo", /* required! */ 68 | "amount": 22.45 /* optional, must be valid decimal if provided */ 69 | } 70 | ``` 71 | **Response:** 72 | ``` 73 | 33 /* <-- this is the id of the newly-created un-tagged receipt */ 74 | ``` 75 | 76 | ### GET /receipts 77 | **Effect:** Return a list of all receipts in the system. 78 | 79 | **Request Body:** 80 | *None* 81 | 82 | **Response:** 83 | ```json 84 | [ 85 | { 86 | "id": 5, 87 | "merchant": "Gerry's Ice Cream", 88 | "amount": 22.50 89 | }, 90 | { 91 | "id": 3, 92 | "merchant": "Starbux" 93 | } 94 | ] 95 | ``` 96 | 97 | ### PUT /tags/{tag} 98 | **Effect:** Categorize a receipt by tagging it. Tags are simple short character strings that are user-defined, 99 | (not pre-defined). To associate a receipt with two tags, this endpoint would need to be executed twice - once for each tag. If a receipt is *already* tagged with a specific tag (say "t1"), the effect of hitting this endpoint (for "t1") will be to un-tag the receipt for the specific tag, but no other tags will be affected. 100 | 101 | **Request Body** 102 | ```json 103 | 35 /* <-- this is the id of the receipt to tag / untag */ 104 | ``` 105 | 106 | **Response** 107 | *None* / no response is required from the server beyond a 200/OK HTTP Response code. To do this using 108 | the `JAX-RS` framework, simply declare your endpoint function to return `void`. e.g. 109 | 110 | ```java 111 | @PUT 112 | @Path("/tags/{tag}") 113 | public void toggleTag(@PathParam("tag") String tagName) { 114 | // 173 | ``` 174 | Here, `` should be your server url (without the angle brackets), e.g., 175 | `python grade_a2.py http://localhost:8080`. 176 | You might need to install a Python library called `requests` used for making http requests very easily. 177 | Installing library in python is simple. You can use `pip`, a Python package manager, do install `request` library. 178 | `pip install requests`. You can install `pip` from https://pip.pypa.io/en/stable/installing/. 179 | 180 | 181 | **UPDATE** 182 | Added support to check CircleCI badge directly from the Github.

The goal of this assignment 7 | is to build a working HTML, CSS + Java Script single-page application that uses the 8 | REST server you built in the last homework. 9 | 10 | You will need to write and test the application, and ultimately deploy the application 11 | to the cloud. 12 | 13 | **No additional PR's are necessary unless you change your server url.** 14 | 15 | To complete the assignment you must complete the following: 16 | 1. Build a SPA (Single Page Application) that conforms to the UI Spec 17 | 2. Integrate your SPA into your Server 18 | 3. Deploy the API to AWS 19 | 20 | Do **NOT** use page auto-reload(e.g., using `location.reload()`) to refresh the changes. 21 | You are supposed to update the DOM elements on the fly using Javascript. 22 | 23 | 24 | *Important: Modern browser security restricts scripts running on particular 25 | domains to that domain only. If you are developing and encounter errors 26 | regarding Mixed Media or Same-origin policy, you can cautiously consider 27 | disabling security in your browser for development purposes. To do this on OSX, 28 | you must quit Chrome completely and then start Chrome from the command-line with special flags:* 29 | ``` 30 | /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --allow-running-insecure-content --args --disable-web-security --user-data-dir 31 | ``` 32 | 33 | If you have Firefox, you can use 34 | [CORS](https://addons.mozilla.org/en-US/firefox/addon/cors-everywhere/) plugin, 35 | that will allow to evade the browser security checks. Once installed you have to 36 | activate it by clicking the small plugin icon on the status bar (top right, 37 | probably). Remember to disable it when you are not testing your app---the 38 | security checks in the browser are there for good reason and disabling them 39 | with this plugin might be problematic. So use it carefully. 40 | 41 | 42 | 43 | ## 1. Building the SPA 44 | Your assignment is to create a Single-Page Application that uses the API you 45 | created in Assignment A2 to store and retrieve receipts, and add and delete tags. 46 | 47 | To make the assignment to be *auto-grade-able*, you must follow specific conventions outlined 48 | in this document with respect to the structure of your HTML and the use of class and id attributes 49 | in specific locations. 50 | 51 | Beyond these simple constraints, you are free to style and compose your application as you see fit: 52 | 53 | #### Initial Sate 54 | ![](is.png) 55 | 56 | When your application opens, your application should query and display all receipts in the database. 57 | Fields for Time, Merchant, Amount and tags are required. 58 | 59 | 0. All receipts should be under a `DIV` with the id `receiptList`. E.g., `
` node. 60 | 1. Every receipt must be represented by a single element of the form `
...
`. The receipt element may have any internal structure you desire. 62 | Receipts must be selectable using `$('.receipt')`. 63 | 64 | 2. Every receipt must have the following fields available: `merchant`, `amount` and `tags`. 65 | * The merchant must be selectable using the following JQuery selector: `$('.merchant', $('.receipt')[0]).text()`. 66 | * The amount must be selectable using the following JQuery selector: `$('.amount', $('.receipt')[0]).text()`. Don't add any '$' or white spaces around the amounts in the column. 67 | * The tags must be selectable using the following JQuery selector: `$('.tags', $('.receipt')[0]).text()`. 68 | 69 | #### Add New Receipt 70 | ![](ar.png) 71 | 72 | Clicking on the ‘add receipt’ button should add a receipt-entry node to the DOM that allows the user to enter a new receipt with merchant (required) and amount (optional) values. Hitting ‘save’ will POST to the `/receipts` endpoint of your API. Hitting `cancel` will close the form and discard any values entered. Errors from the server should appear somewhere in the receipt-entry node so the user can understand and correct any problems. 73 | 74 | 1. The add button for receipts MUST have id `add-receipt` and be selectable via `$('#add-receipt')`. A `click` event 75 | fired on the element should show the add-receipt dialogue box. 76 | 77 | 2. You must use `INPUT` elements for the ‘merchant’ and ‘amount’ entry, and the `INPUT` elements must have id's `#merchant` and `#amount`. 78 | 79 | 3. The save and cancel button must have ids `save-receipt` and `cancel-receipt` and respond to `click` events. 80 | 81 | 82 | #### Add Tags to Existing Receipts 83 | ![](at.png) 84 | 85 | The application supports the tagging of receipts with arbitrary user-defined tags. 86 | 87 | * Every receipt row must have a button with class `add-tag` that responds to `click` events. When clicked, an `INPUT` element with class `tag_input` must be added to the DOM **as a child of the receipt row upon which add-tag was clicked** and should be selectable by JQuery using `$('INPUT.tag_input', receiptNode)`. The input element should execute a `PUT` request against your `PUT /tags/{tag}` API when the user strikes the `Enter` key in the `INPUT` element. 88 | 89 | * The result of a successful `PUT` operation is the removal of the `tag_input` element from the DOM, and the addition of an element displaying the name of the tag now associated with the receipt. 90 | 91 | * Tag elements must have a `tagValue` class attribute, and the value of the tags for a particular 92 | receipt must be selectable via e.g. `$('.tagValue', receiptNode)` 93 | 94 | * Tag elements must respond to `click` events which execute a `PUT` request against your API to 95 | dissociate the receipt from the tag that was clicked. 96 | 97 | 98 | ## 2. Integrate the SPA into your Server 99 | Adam will provide a snippet of code to support you in this regard. Update your [Skeleton](https://github.com/amfleming/skeleton) code from Adam's repo, and look at [this commit](https://github.com/amfleming/skeleton/commit/9a8925afa9756cad50a21d1cbf42f8d8deb66d4f). 100 | 101 | ## 3. Deploy to AWS 102 | Exactly the same as we did in Assignment 02. 103 | 104 | ## 4. [Auto-grader](grade_a3.py) 105 | Testing UI requires some extra maneuvers! We will use `Selenium` with `Firefox` browser to automate the testing. 106 | For this you have to do two things. 107 | 1. install Python `selenium` library (`pip install selenium`), 108 | 2. download Firefox web driver from https://github.com/mozilla/geckodriver/releases, extract it, and copy the binary to your `PATH`. 109 | For Linux/OSX move that binary to `/usr/local/bin/'. For windows follow the detailed instruction given in http://selenium-python.readthedocs.io/installation.html. 110 | 111 | After this, run the [auto-grader script](grade_a3.py) as, 112 | ```bash 113 | $ python grade_a3.py 114 | ``` 115 | 116 | E.g., `python grade_a3.py http://localhost:8080` 117 | 118 | Let me know if you find issues in the code. 119 | Make sure your server is running! I used Python 3.6 to test the script in my machine. 120 | 121 | 122 | -------------------------------------------------------------------------------- /assignments/a3/ar.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/CT-CS5356-Fall2017/cs5356/570403fb1321de97710c90c961ac040f7ad51c16/assignments/a3/ar.png -------------------------------------------------------------------------------- /assignments/a3/at.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/CT-CS5356-Fall2017/cs5356/570403fb1321de97710c90c961ac040f7ad51c16/assignments/a3/at.png -------------------------------------------------------------------------------- /assignments/a3/geckodriver: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/CT-CS5356-Fall2017/cs5356/570403fb1321de97710c90c961ac040f7ad51c16/assignments/a3/geckodriver -------------------------------------------------------------------------------- /assignments/a3/grade_a3.py: -------------------------------------------------------------------------------- 1 | import sys 2 | import requests 3 | import random 4 | import string 5 | import re 6 | import time 7 | 8 | try: 9 | from selenium import webdriver 10 | from selenium.webdriver.common.keys import Keys 11 | except ImportError: 12 | print(""" 13 | Install selenium for python. `pip install -U selenium`.

We will finish our work of building a 6 | receipt storing service by extending the functionality with Optical Character 7 | Recognition (OCR) using [Google Cloud Vision 8 | API](https://cloud.google.com/vision/). The purpose of the OCR integration is to 9 | speed the entry of receipts. The output of successful OCR is suggestions for 10 | new receipt creation, specifically `Merchant` and `Amount`. 11 | 12 | **TL;DR** 13 | The goal is to add a button to capture image of a receipt, process the image to 14 | extract the merchant and the total amount, and prompt the user to add the 15 | receipt with suggested merchant and amount from OCR. 16 | 17 | ## 0. Setup Google Vision API 18 | Here is a video of the steps required to create a service account, download 19 | the api key file, and enable the Google Vision API: 20 | [Setup Video](./setup.mp4). **Restrict Access of your service key.** While 21 | creating the service key, click on the dropdown `Role`, and select `Roles` > 22 | `Role Viewer`. 23 | ![How to set roles?](./roles.png). 24 | The service account key, by default, has lot more permission than you want 25 | them to have. Restricting the role will ensure that the key is not misused. 26 | 27 | 29 | 31 | Fetch the updated [`Skeleton`](https://github.com/amfleming/skeleton) code, which is 32 | already updated with a controller for querying Vision API. You have to update 33 | it with correct `gc_api_file.json` that you downloaded form setup step above. 34 | Set the environment variable `GOOGLE_APPLICATION_CREDENTIALS=./gc_api_file.json`. 35 | In Linux, MAC, Windows Cygwin shell org Git Bash, this can be done by running `export 36 | GOOGLE_APPLICATION_CREDENTIALS=./gc_api_file.json`, just before calling `gradle run`. 37 | 38 | 39 | ## 1. Extracting merchant name and total price 40 | Google OCR will return the text recovered from the captured image. From the 41 | returned text you have to extract the merchant name and the total price. We 42 | will use two simple heuristic to extract these information. Get the extracted 43 | text sorted vertically from top to bottom. Assume the top-most non-numerical 44 | text is the `merchant`, and the last decimal text (of the format `23.45`, or 45 | `43.00`) is the `total`. 46 | 47 | You must create the following endpoint, which accepts as input a `Base64` 48 | encoded string representing a PNG image, and returns a JSON object of the 49 | form `{"merchantName": ..., "amount": ...}`. 50 | 51 | 52 | Assuming you are running your server locally and you have a file containing a 53 | base-64-encoded PNG in `receipt_img.png.b64`, the following CURL request should 54 | succeed: 55 | ``` 56 | curl -H 'Content-Type: text/plain' --data "@./receipt_img.png.b64" localhost:8080/images 57 | ``` 58 | 59 | ## 2. Capturing a photo of a receipt 60 | You should have a button your page (preferably beside the current add button 61 | for receipts) for starting the camera. The button should be selectable by 62 | the selector `$('#start-camera')`. Clicking the button should start the 63 | camera. There should be a button selectable by `$('#take-pic')`, clicking 64 | which will capture the photo. Also, once the `#take-pic` is clicked it should 65 | trigger a call to the backend to run OCR on the taken image using Google 66 | Vision API. Finally, you must destroy the `video` DOM element and transfer 67 | the suggestions from OCR into two user-editable inputs that show the results 68 | of the OCR parsing. If the user is happy with the results, they should be 69 | able to add the new receipt with the suggestions (or modify the suggestions, 70 | or cancel). It is reasonable to re-use your 'Add Receipt' form from A3 here. 71 | 72 | There should be a cancel button that should close the video and should cancel 73 | the process of adding a receipt. The id of that button should be 74 | `take-pic-cancel`. 75 | 76 | The UX for this assignment should follow ![this spec](./spec.png) 77 | 78 | Code we wrote in class is [in this plnkr](https://plnkr.co/edit/yhAOTeADsTYeRcgqJ3hr?p=preview) 79 | 80 | 88 | 89 | ## 3. Deploy in AWS 90 | Finally deploy your updated code in AWS. Update the 91 | [`README.md`](../../README.md) **if and only if** your URL changed. We will 92 | grade your assignment using that URL you attached in the 93 | [`README.md`](../../README.md) file. 94 | 95 | ## 4. Testing + Auto grader 96 | - Chrome only allows access to devices (the camera) in Secure Contexts. That means SSL-enabled websites, and when 97 | developing using `localhost`. If you want to test your site once it is deployed, you will need to set a special 98 | flag unless you have configured SSL in order to get access to the camera 99 | ``` 100 | /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --unsafely-treat-insecure-origin-as-secure="http://your-site-url-here" --user-data-dir=/tmp 101 | ``` 102 | 103 | - To test using a specific receipt (OSX), you can set some special flags that feed a pre-defined 104 | video as the video device as below. 105 | (Sample receipts iinclude [receipt_vid.y4m](./receipt_vid.y4m) which should produce `{"merchantName":"Main","amount":29.01}` and 106 | [cappones.y4m](./cappones.y4m) which should produce `{"merchantName":"Cappones","amount":28.86}`) 107 | ```bash 108 | /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --use-fake-device-for-media-stream --use-file-for-fake-video-capture=receipt_vid.y4m --use-fake-ui-for-media-stream --user-data-dir=/tmp 109 | ``` 110 | - R.I.P. Autograder. We'll be grading this assignment by-hand. To get full credit you should make sure that the following things are true: 111 | - Receipts can be added by-hand per A3 (no regressions!) 112 | - Tags can be added + removed per A3 (no regresions!) 113 | - It is possible, per the UX for this assignment, click a button that opens the camera 114 | - You can take a snapshot of whatever image is visible in the Video element 115 | - The image data is sent to the server 116 | - An algorithm satisfying this assignment is executed on the results of GV's OCR 117 | - The results of the algorithm are fed into the manual-entry form, which works per A3 118 | 119 | ## 5. Retain old functionalities. 120 | Please make sure that your server have all the functionalities specified in A2 and A3, especially `/netid` endpoint. 121 | 122 | 123 | # Extra Credit 124 | Two forms of extra credit are possible on this assignment. 125 | 126 | ## EC1. Custom Domain (+3 pts) 127 | Purchase a custom domain for your application and setup DNS. [[Tutorial](http://docs.aws.amazon.com/Route53/latest/DeveloperGuide/routing-to-ec2-instance.html)] 128 | Your DNS configuriation should create an `A Record` that points to your ECS instance. 129 | 130 | ... Unless of course you choose to setup SSL! In which case: 131 | 132 | ## EC2. Setup SSL (+5 pts) 133 | Setup a load balancer for your application (ALB or ELB). Use Amazon 134 | [AWS Certificate Manager](https://aws.amazon.com/blogs/aws/new-aws-certificate-manager-deploy-ssltls-based-apps-on-aws/) 135 | to generate an SSL Certificate. Apply the certificate to the 136 | load balancer. To get credit for this, Chrome must display a 137 | Green Lock when your site is loaded: 138 | 139 | ![](https://media.amazonwebservices.com/blog/2016/ssl_tls_indicator_on_amazon_site_1.png) 140 | 141 | To get credit for SSL, **you must also setup a custom domain** 142 | You cannot get credit for SSL without setting up a custom domain. 143 | 144 | ## EC3. Thumbnails (+12 pts) 145 | For receipts created via image capture, crop the image used for OCR 146 | and display it in your app as a thumbnail. 147 | 148 | To determine the cropping dimensions, you must compute the *Minimum Bounding Rectangle* that 149 | includes all the OCR-recognized text. Crop to the *MBR* and display the cropped image 150 | in your application. Visually the method for determining appropriate crop is below: 151 | 152 | ![](receipt_cropping_method.png) 153 | -------------------------------------------------------------------------------- /assignments/a4/cappones.y4m: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/CT-CS5356-Fall2017/cs5356/570403fb1321de97710c90c961ac040f7ad51c16/assignments/a4/cappones.y4m -------------------------------------------------------------------------------- /assignments/a4/grade_a4.js: -------------------------------------------------------------------------------- 1 | 'use strict'; 2 | 3 | 4 | const puppeteer = require('puppeteer'); 5 | const _ = require('lodash'); 6 | const crypto = require('crypto'); 7 | const path = require('path'); 8 | 9 | // For Server 10 | const express = require('express'); 11 | const morgan = require('morgan'); 12 | const fs = require('fs'); 13 | 14 | const video_url = [ 15 | 'receipt_vid.y4m', 16 | 'cappones.y4m' 17 | ]; 18 | 19 | const receipt_matchers = [ 20 | rcpt_json => /"Main/.test(rcpt_json) && /29\.01/.test(rcpt_json), 21 | rcpt_json => /"Cappones/.test(rcpt_json) && /28\.86/.test(rcpt_json) 22 | ] 23 | const video_idx = Math.floor(Math.random() * 2); 24 | 25 | function rand_string(n) { 26 | var text = ""; 27 | var possible = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789"; 28 | 29 | for (var i = 0; i < n; i++) 30 | text += possible.charAt(Math.floor(Math.random() * possible.length)); 31 | return text; 32 | } 33 | 34 | async function add_receipt(page) { 35 | var rcpt = { 36 | merchant: 'M_' + rand_string(4), 37 | amount: (Math.floor(Math.random() * 10000)/100.0).toString(), 38 | tags: [] 39 | } 40 | await page.click('#add-receipt'); 41 | // Enter merchant 42 | await page.click('#merchant'); 43 | await page.type(rcpt.merchant); 44 | 45 | // Enter amount 46 | await page.click('#amount'); 47 | await page.type(rcpt.amount); 48 | 49 | await page.click('#save-receipt'); 50 | return rcpt; 51 | } 52 | 53 | function add_tag(i, tag) { 54 | var sel = '#receiptList .receipt'; 55 | var rcpt_elem = $(sel)[i]; 56 | // alert(rcpt_elem + ' --> ' + sel + ' --> ' + i); 57 | var e_up = jQuery.Event("keyup", {which: 13, keyCode: 13}); 58 | var e_press = jQuery.Event("keypress", {which: 13, keyCode: 13}); 59 | $('.add-tag', rcpt_elem).click(); 60 | $('.tag_input', rcpt_elem).val(tag).trigger(e_up).trigger(e_press); 61 | console.log($('.tagValue', rcpt_elem).text()); 62 | } 63 | 64 | function del_tag(i) { 65 | const sel = '#receiptList .receipt'; 66 | const rcpt_elem = $(sel)[i]; 67 | // alert(rcpt_elem + ' --> ' + sel + ' --> ' + i); 68 | const e_up = jQuery.Event("keyup", {which: 13, keyCode: 13}); 69 | const e_press = jQuery.Event("keypress", {which: 13, keyCode: 13}); 70 | const tags = $('.tagValue', rcpt_elem); 71 | const j = Math.floor(Math.random() * tags.length); 72 | const tag_val = $(tags[j]).text().trim(); 73 | $(tags[j]).click(); 74 | return tag_val; 75 | } 76 | 77 | 78 | /* Tests if the additional element is in the updated_list */ 79 | function test_addition(original_list, updated_list, expected, thing='', ret_log={}) { 80 | // Compute the set of 'diffs' (those in the updated list, but not in original list) 81 | let diffs = _.map(updated_list, JSON.stringify); 82 | original_list.forEach(orig => { 83 | let idx = _.indexOf(diffs, JSON.stringify(orig)); 84 | _.pullAt(diffs, idx); 85 | }); 86 | 87 | if (diffs.length !== 1) { 88 | ret_log['msg'] += `Expected 1 ${thing} to be added.

Cornell Tech Studio classes give our students tools to imagine and design such products and 16 | services. Cornell Tech technical classes give our students the depth to come up with innovative solutions to make such 17 | products and services real. 18 | 19 | The goal of the "Building Startup Systems" class is to give our students a concrete experience of designing, 20 | implementing and deploying a workable system that can be demo-ed and/or used by early users. 21 | The "Building Startup Systems" class is a 1-credit course, 3 hours per week for 5 weeks. The class will run 22 | October 18-November 22. 23 | 24 | The class will be anchored around the design, implementation and deployment of a typical webapp. 25 | The topics will be presented in the context of a project that all students will have to work on. 26 | The class will also bring together some software engineering best practices. Students will work on the project in pairs 27 | (note: each student will be paired twice for the duration of the class). 28 | 29 | 30 | 31 | ### Prerequisites 32 | 33 | * Comfortable managing systems, processes, and editing files using only unix shell 34 | * Experience with at least one well-typed or compiled language (Scala, Java, C++, etc.) 35 | * Experience with at least one scripted language (JavaScript, Ruby, PHP, node.js, Python, etc.) 36 | * Experience with HTML and CSS. 37 | 38 | -------------------------------------------------------------------------------- /course/grading.md: -------------------------------------------------------------------------------- 1 | ### Grading 2 | 3 | Course grading is based only completion and sophistication of the course project. 4 | 5 | Points are earned through building the systems required to support the class project. You will work as a team, however the points you earn as an individual are determined by the product of the *points for the work* x *your understanding of the work*. Points for the work and your understanding for the work will be judged in an in-person interview taking ~20 mins during finals week, by class staff. 6 | 7 | There are 4 buckets you can earn points in, based on the *sophistication*, *quality* and *your understanding* of the work. 8 | 9 | The buckets are: 10 | 11 | 1. *Mobile Client* 12 | 2. *API* 13 | 3. *Database* 14 | 4. *DevOps* 15 | 16 | You can earn a number of points per bucket per project based on your accomplishments 17 | in that domain. 18 | 19 | 20 | #### Mobile Client 21 | 22 | * +1 point for having a mobile app than makes API calls 23 | * +1 point for a realistic worklflow that encompases all reasonable app features 24 | * +1 point for stunning UX with animated transitions or fantastic mapping features 25 | * +1 point for completion of BOTH driver and hailer sides of app (these can be one app with a bifurcated UX based on user-type) 26 | 27 | #### API 28 | * +1 point for running server application 29 | * +1 point for database logic 30 | * +1 point for Swagger.io (or similar) self-generating API docs 31 | * +1 point for 3rd party API integration (e.g. sending SMS messages or Push Notifications) 32 | 33 | #### Database 34 | * +1 point for having a database with a reasonable schema 35 | * +1 point for 2 or more collections or tables 36 | * +1 point for driver / user selfie images, captured on device + stored in the cloud 37 | 38 | #### DevOps 39 | * +1 point for material tests and working CI 40 | * +1 point for automated deployment by the CI tool if tests pass 41 | 42 | 43 | ## Grading 44 | ``` 45 | 13 pts - A+ 46 | 9-12 pts - A 47 | 7-8 pts - A- 48 | 6 pts - B+ 49 | 5 pts - B 50 | 4 pts - B- 51 | 3 pts - C 52 | 1-2 pts - D 53 | ``` 54 | -------------------------------------------------------------------------------- /grading/README.md: -------------------------------------------------------------------------------- 1 | 1. node download_a3.js 2 | this will gather js, and put it into `output/` 3 | 4 | 2. ./moss.perl -l javascript output/*.js 5 | 6 | 7 | 3. `cd mossum && python mossum/mossum.py` 8 | -------------------------------------------------------------------------------- /grading/download_js_a3.js: -------------------------------------------------------------------------------- 1 | const rp = require('request-promise'); 2 | const fs = require("fs"); 3 | const cheerio = require('cheerio'); 4 | 5 | var lines = fs.readFileSync('../README.md').toString().split('\n'); 6 | var re = /([a-z]{2,3}[0-9]{2,4}) ?- ?\[(htt[^\]]*)\]/; 7 | 8 | 9 | var x = 0; 10 | lines.forEach(line => { 11 | //if(x == 10) 12 | // return; 13 | 14 | //console.log(lines[i]); 15 | var matches = re.exec(line); 16 | if(matches && !matches[2].endsWith('grading.html')) { 17 | console.log(`${matches[1]} \t ${matches[2]}`); 18 | var netid = matches[1]; 19 | var url = matches[2]; 20 | 21 | //if(netid != 'rs2468') 22 | // return; 23 | 24 | var options = { 25 | uri: url, 26 | headers: { 27 | 'Accept': 'text/html' 28 | }, 29 | transform: function (body) { 30 | return cheerio.load(body); 31 | } 32 | }; 33 | 34 | rp(options).then($ => { 35 | //console.log($.html()); 36 | //console.log(`---------- ${netid} -----------`); 37 | // check out the script tags 38 | var rv = ''; 39 | $('script').each((i, script) => { 40 | var src = $(script).attr('src'); 41 | var contents = $(script).contents() ?

The tool generates a graph for 9 | (multiple) results from Moss, which can help in identifying groups of students 10 | that have shared solutions. 11 | 12 | The tool can also generate a report, which shows which solutions are similar 13 | between all pairs of students. When submitting multiple parts of an assignment 14 | to Moss, this can help in identifying which students have multiple similar 15 | solutions. 16 | 17 | 18 | Installation 19 | ------------ 20 | 21 | The script can be installed via `pip`: 22 | 23 | ``` 24 | pip install --allow-all-external --process-dependency-links git+https://github.com/hjalti/mossum@master 25 | ``` 26 | 27 | (The `--process-dependency-links` will be deprecated in pip 1.6, but hopefully 28 | pydot will have support for Python 3 in PyPI by then) 29 | 30 | Basic usage 31 | ----------- 32 | 33 | After installation, the script can be called as follows 34 | 35 | ``` 36 | mossum MossURL1 MossURL2 ... MossURLn 37 | ``` 38 | 39 | If no URLs are specified as parameters, the URLs are read from the 40 | standard input. In this example, mossum generates *n* PNG images, that 41 | show the relationship between the submissions in each result page. The name of 42 | each image is obtained from the comment used when submitting to Moss (the `-c` 43 | flag). 44 | 45 | By default mossum only shows a link between two submissions if the match Moss 46 | finds 47 | * accounts for more than 90% of either submission, and 48 | * accounts for more than one line of either submission. 49 | 50 | The percentage and number of lines can be changed using the `--min-percent` 51 | (`-p`) option and `--min-lines` (`-l`) option, respectively. 52 | 53 | For example, when called with 54 | 55 | ``` 56 | mossum -p 95 -l 30 MossURL1 MossURL2 ... MossURLn 57 | ``` 58 | 59 | mossum only shows a link between submission if either match accounts for more 60 | than 95% of the submission or more than 30 lines are matched. 61 | 62 | More options 63 | ------------ 64 | 65 | ### Transformation 66 | 67 | When submitting to Moss, the whole path of all files is shown. When 68 | summarizing, we can extract relevant information from the path. This can also 69 | be useful if assignments are submitted in multiple files. In which case, we can 70 | extract relevant information from the path (e.g., student ID), when 71 | summarizing. 72 | 73 | The transformation option takes a regular expression as a parameter. If the 74 | regular expression contains groups, the transformed submission names are formed 75 | from the strings matched inside all groups, joined by an underscore. If the 76 | regular expression contains no groups, only the part of path that matches the 77 | regular expression is used as the transformed name. 78 | 79 | For example, if the submissions are stored in the following directory structure 80 | 81 | ``` 82 | /// 83 | ``` 84 | 85 | for example, 86 | 87 | ``` 88 | assignment1/1337/fred24/a1_part1.cpp 89 | assignment1/1337/fred24/a1_part2.cpp 90 | assignment1/1337/fred24/a1_part3.cpp 91 | assignment1/1337/sarah37/a1_p1.cpp 92 | assignment1/1337/sarah37/a1_part2.cpp 93 | assignment1/1337/sarah37/a13.cpp 94 | ``` 95 | 96 | the student ID can be extracted using the regular expression `*./(.+)/.*` and 97 | if we want the name to contain the assignment name and the student ID, we can 98 | use the regular expression `(.*)/.*/(.*)/.*`. 99 | 100 | ### Anonymize 101 | 102 | The summarization can be anonymized using the `--anonymize` or `-a` flag. When 103 | using this, all names are substituted with a random word. This is useful for 104 | frightening students. 105 | 106 | ### Report 107 | 108 | When assignments are split into parts and each part is submitted to Moss 109 | separately, it can be hard to get an overview of which students have many 110 | submissions in common. If the `--report` or `-r` flag is specified, mossum 111 | generates a *report*. The report generated shows which matches each pair of 112 | students have in common. The report is sorted, such that the pair of students 113 | with the most matches in common come first. 114 | 115 | Calling 116 | 117 | ``` 118 | mossum -r -t "*./(.+)/.*" MossURL1 MossURL2 ... MossURLn 119 | ``` 120 | 121 | would yield a report with entries similar to 122 | 123 | ``` 124 | fred24 and sarah37: 125 | part1: http://moss.stanford.edu/results/???/match??.html 126 | part2: http://moss.stanford.edu/results/???/match??.html 127 | part3: http://moss.stanford.edu/results/???/match??.html 128 | ``` 129 | 130 | The reports are stored in `.txt`, where `` is either 131 | specified by the `--output` or `-o` flag or obtained from the name of the 132 | assignments (extracted from the Moss pages). 133 | 134 | ### Format 135 | 136 | The format of the image generated by mossum can be changed using the `--format` 137 | or `-f` option. Mossum uses Graphviz to generate graphs. All output formats 138 | supported by Graphviz are therefore supported by mossum. See [Graphviz output 139 | formats](http://www.graphviz.org/doc/info/output.html). 140 | 141 | 142 | ### Links 143 | 144 | The `--show-links` or `-s` option can be used to add hyperlinks, to the Moss 145 | page of the match, which is represented by the edges in the graph, generated by 146 | mossum. 147 | 148 | Note that the hyperlinks only work if the specified format is `svg` or `xlib`. 149 | 150 | For example, calling 151 | 152 | ``` 153 | mossum -s -f svg -t "*./(.+)/.*" -o assignment MossURL1 MossURL2 ... MossURLn 154 | ``` 155 | 156 | will generate a SVG image file. If this file is opened in a browser, the 157 | matches found by Moss, which represent each edge, can be opened by clicking the 158 | `M` displayed on each edge. 159 | 160 | If you are using X, you can specify the format `xlib`. In this case mossum 161 | displays the graph in an Xlib window, and the graph is therefore not saved to 162 | a file. 163 | 164 | ### Filters 165 | 166 | It is possible to to add or remove a name from the collection of assignments 167 | using filters. There are four filter options, all of which take a list of names 168 | as arguments. The following filters are available. 169 | 170 | * `--filter N1 N2 ... Nn`: Only show connections between the specified names. 171 | No other connections are shown. 172 | 173 | * `--filteri N1 N2 ... Nn`: Only show connections including at least one of 174 | specified names. No other connections are shown. 175 | 176 | * `--filterx N1 N2 ... Nn`: Do not show connections between the specified 177 | names. All other connections are shown. 178 | 179 | * `--filterxi N1 N2 ... Nn`: Do not show connections where one of the specified 180 | names is involved. All other connections are shown. 181 | -------------------------------------------------------------------------------- /grading/mossum/bin/mossum: -------------------------------------------------------------------------------- 1 | #!/usr/bin/env python 2 | # -*- coding: utf-8 -*- 3 | 4 | import os 5 | import sys 6 | from mossum import mossum 7 | 8 | if __name__ == "__main__": 9 | mossum.main() 10 | -------------------------------------------------------------------------------- /grading/mossum/mossum/__init__.py: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/CT-CS5356-Fall2017/cs5356/570403fb1321de97710c90c961ac040f7ad51c16/grading/mossum/mossum/__init__.py -------------------------------------------------------------------------------- /grading/mossum/mossum/mossum.py: -------------------------------------------------------------------------------- 1 | #!/usr/bin/env python 2 | # -*- coding: utf-8 -*- 3 | 4 | """ 5 | Mossum is a tool for summarizing results from Stanford's Moss.
