Great! First, read this page (including the small print at the end). 2 | 3 | ### Before you contribute 4 | 5 | Before we can use your code, you must sign the 6 | [Google Individual Contributor License Agreement](https://developers.google.com/open-source/cla/individual?csw=1) 7 | (CLA), which you can do online. The CLA is necessary mainly because you own the 8 | copyright to your changes, even after your contribution becomes part of our 9 | codebase, so we need your permission to use and distribute your code. We also 10 | need to be sure of various other things—for instance that you'll tell us if you 11 | know that your code infringes on other people's patents. You don't have to sign 12 | the CLA until after you've submitted your code for review and a member has 13 | approved it, but you must do it before we can put your code into our codebase. 14 | 15 | Before you start working on a larger contribution, you should get in touch with 16 | us first through the issue tracker with your idea so that we can help out and 17 | possibly guide you. Coordinating up front makes it much easier to avoid 18 | frustration later on. 19 | 20 | ### Code reviews 21 | 22 | All submissions, including submissions by project members, require review. We 23 | use Github pull requests for this purpose. 24 | 25 | ### The small print 26 | 27 | Contributions made by corporations are covered by a different agreement than 28 | the one above, the Software Grant and Corporate Contributor License Agreement. 29 | -------------------------------------------------------------------------------- /bin/shapeshift.dart: -------------------------------------------------------------------------------- 1 | // Copyright 2014 Google Inc.

Understand how the shape of the Dart SDK is shifting.

26 | 27 |

Shapeshift executes against two versions of Dart docgen-generated 28 | APIs to expose how your API has changed. Shapeshift generates a set 29 | of markdown files that list API differences in your Dart package.

Shapeshift generates a set of markdown files 8 | that list API differences in your Dart package. 9 | 10 | Shapeshift can be used as a command-line script, or as Dart library. 11 | 12 | The shapeshift.dart script 13 | ========================== 14 | 15 | The shapeshift package comes with a command-line tool, `bin/shapeshift.dart`. 16 | This tool can read JSON-formatted API files (generated by dartdoc), and output, 17 | in Markdown format, a list of differences. 18 | 19 | Basic example 20 | ------------- 21 | 22 | Assuming you have two versions of your docgen-generated docs at: 23 | 24 | ```bash 25 | /Code/my_package/docs/docs-v1.6.0/ 26 | /Code/my_package/docs/docs-v1.7.0/ 27 | ``` 28 | 29 | Then you can run the following command to generate reports of the API 30 | differences. 31 | 32 | ```bash 33 | dart bin/shapeshift.dart \ 34 | --base=/Code/my_package/docs \ 35 | --out=./diff-1.6.0_1.7.0 \ 36 | docs-v1.6.0 \ 37 | docs-v1.7.0 38 | ``` 39 | 40 | In this command, `--base` specifies the directory where your two documentation 41 | directories live. `--out` specifies a new or existing directory where you want 42 | the output markdown files to be written. The final two arguments are the 43 | directory with the _old_ and the directory with the _new_ documentation. 44 | 45 | This command will create the output directory, if it wasn't there, and write a 46 | markdown file for each library that was examined. For example, if a 47 | `dart-async.json` file was found, documenting the `dart:async` library, then 48 | the output will include a `dart:async.markdown` file. 49 | 50 | Each library's markdown file will then include all of the changes found for the 51 | library itself, and for every class within the library. 52 | 53 | The directory of markdown files works surprisingly well with 54 | [Jekyll](http://jekyllrb.com/) and Jekyll's basic template, but we're working 55 | on more streamlined output options. 56 | 57 | Options 58 | ------- 59 | 60 | The shapeshift Dart script accepts the following options: 61 | 62 | * `--base` is the file path that the two directories (old and new) have in 63 | common. 64 | * `--out` is an optional directory where the API changes can be written to. 65 | Shapeshift will write a separate Markdown file for each library it finds. 66 | Each Markdown file will include changes for all member classes of a library. 67 | If `--out` is not used, the differences, still in Markdown format, will be 68 | printed to stdout. 69 | 70 | Using the Dart library 71 | ====================== 72 | 73 | Shapeshift can also be used with other Dart code as a library. I would 74 | recommend importing `'package:shapeshift/shapeshift_common.dart'`. The 75 | [tests](test/shapeshift/) can be used as examples. 76 | 77 | `shapeshift_common` library example 78 | --------------------------------------------------- 79 | 80 | Assuming you have two versions of a class's API sitting on disk, say at 81 | `v1/foo.Foo.json`, and `v2/foo.Foo.json`, you may diff them as follows: 82 | 83 | ```dart 84 | import 'package:shapeshift/shapeshift_common.dart'; 85 | 86 | void main() { 87 | String v1 = new File('v1/foo.Foo.json')..readAsStringSync(); 88 | String v2 = new File('v2/foo.Foo.json')..readAsStringSync(); 89 | 90 | // Calculate the diff between the two APIs. 91 | DiffNode diff = diffApis(v1, v2); 92 | 93 | // ReadableStringSink is just a class that acts like a StringSink, but can be 94 | // read at any point. You can also use a File handle. 95 | ReadableStringSink io = new ReadableStringSink(); 96 | 97 | // The MarkdownWriter takes a callback that will instantiate the write 98 | // target, if it needs to be written to. 99 | MarkdownWriter writer = new MarkdownWriter(() => io, false); 100 | 101 | // Create a new ClassReporter for the diff, which can report to the writer. 102 | // And write! 103 | new ClassReporter(diff, writer).report(); 104 | 105 | // Now io contains the report, in Markdown format. 106 | print(io.read()); 107 | } 108 | ``` 109 | 110 | `shapeshift_common` API 111 | ----------------------- 112 | 113 | TODO: Publish shapeshift as a package, so that it's API is online. 114 | 115 | For now, the [tests](test/shapeshift/) serve as good examples of how to use the 116 | API. 117 | 118 | License 119 | ======= 120 | 121 | [Apache v2](LICENSE) 122 | 123 | Contributing 124 | ============ 125 | 126 | Contributions welcome!

 14 |       the copyright owner that is granting the License.
 15 | 
 16 |       "Legal Entity" shall mean the union of the acting entity and all
 17 |       other entities that control, are controlled by, or are under common
 18 |       control with that entity. For the purposes of this definition,
 19 |       "control" means (i) the power, direct or indirect, to cause the
 20 |       direction or management of such entity, whether by contract or
 21 |       otherwise, or (ii) ownership of fifty percent (50%) or more of the

 25 |       exercising permissions granted by this License.
 26 | 
 27 |       "Source" form shall mean the preferred form for making modifications,

 32 |       transformation or translation of a Source form, including but
 33 |       not limited to compiled object code, generated documentation,
 34 |       and conversions to other media types.
 35 | 
 36 |       "Work" shall mean the work of authorship, whether in Source or
 37 |       Object form, made available under the License, as indicated by a
 38 |       copyright notice that is included in or attached to the work
 39 |       (an example is provided in the Appendix below).
 40 | 
 41 |       "Derivative Works" shall mean any work, whether in Source or Object
 42 |       form, that is based on (or derived from) the Work and for which the
 43 |       editorial revisions, annotations, elaborations, or other modifications
 44 |       represent, as a whole, an original work of authorship. For the purposes
 45 |       of this License, Derivative Works shall not include works that remain
 46 |       separable from, or merely link (or bind by name) to the interfaces of,
 47 |       the Work and Derivative Works thereof.
 48 | 
 49 |       "Contribution" shall mean any work of authorship, including
 50 |       the original version of the Work and any modifications or additions
 51 |       to that Work or Derivative Works thereof, that is intentionally
 52 |       submitted to Licensor for inclusion in the Work by the copyright owner
 53 |       or by an individual or Legal Entity authorized to submit on behalf of
 54 |       the copyright owner. For the purposes of this definition, "submitted"
 55 |       means any form of electronic, verbal, or written communication sent
 56 |       to the Licensor or its representatives, including but not limited to
 57 |       communication on electronic mailing lists, source code control systems,
 58 |       and issue tracking systems that are managed by, or on behalf of, the
 59 |       Licensor for the purpose of discussing and improving the Work, but
 60 |       excluding communication that is conspicuously marked or otherwise
 61 |       designated in writing by the copyright owner as "Not a Contribution."
 62 | 
 63 |       "Contributor" shall mean Licensor and any individual or Legal Entity
 64 |       on behalf of whom a Contribution has been received by Licensor and

 67 |    2. Grant of Copyright License. Subject to the terms and conditions of
 68 |       this License, each Contributor hereby grants to You a perpetual,
 69 |       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
 70 |       copyright license to reproduce, prepare Derivative Works of,
 71 |       publicly display, publicly perform, sublicense, and distribute the
 72 |       Work and such Derivative Works in Source or Object form.
 73 | 
 74 |    3. Grant of Patent License. Subject to the terms and conditions of
 75 |       this License, each Contributor hereby grants to You a perpetual,
 76 |       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
 77 |       (except as stated in this section) patent license to make, have made,
 78 |       use, offer to sell, sell, import, and otherwise transfer the Work,
 79 |       where such license applies only to those patent claims licensable
 80 |       by such Contributor that are necessarily infringed by their
 81 |       Contribution(s) alone or by combination of their Contribution(s)
 82 |       with the Work to which such Contribution(s) was submitted. If You
 83 |       institute patent litigation against any entity (including a
 84 |       cross-claim or counterclaim in a lawsuit) alleging that the Work
 85 |       or a Contribution incorporated within the Work constitutes direct
 86 |       or contributory patent infringement, then any patent licenses
 87 |       granted to You under this License for that Work shall terminate
 88 |       as of the date such litigation is filed.
 89 | 
 90 |    4. Redistribution. You may reproduce and distribute copies of the
 91 |       Work or Derivative Works thereof in any medium, with or without
 92 |       modifications, and in Source or Object form, provided that You
 93 |       meet the following conditions:
 94 | 
 95 |       (a) You must give any other recipients of the Work or
 96 |           Derivative Works a copy of this License; and
 97 | 
 98 |       (b) You must cause any modified files to carry prominent notices
 99 |           stating that You changed the files; and
100 | 
101 |       (c) You must retain, in the Source form of any Derivative Works
102 |           that You distribute, all copyright, patent, trademark, and
103 |           attribution notices from the Source form of the Work,
104 |           excluding those notices that do not pertain to any part of
105 |           the Derivative Works; and
106 | 
107 |       (d) If the Work includes a "NOTICE" text file as part of its
108 |           distribution, then any Derivative Works that You distribute must
109 |           include a readable copy of the attribution notices contained
110 |           within such NOTICE file, excluding those notices that do not
111 |           pertain to any part of the Derivative Works, in at least one
112 |           of the following places: within a NOTICE text file distributed
113 |           as part of the Derivative Works; within the Source form or
114 |           documentation, if provided along with the Derivative Works; or,
115 |           within a display generated by the Derivative Works, if and
116 |           wherever such third-party notices normally appear. The contents
117 |           of the NOTICE file are for informational purposes only and
118 |           do not modify the License. You may add Your own attribution
119 |           notices within Derivative Works that You distribute, alongside
120 |           or as an addendum to the NOTICE text from the Work, provided
121 |           that such additional attribution notices cannot be construed
122 |           as modifying the License.
123 | 
124 |       You may add Your own copyright statement to Your modifications and
125 |       may provide additional or different license terms and conditions
126 |       for use, reproduction, or distribution of Your modifications, or
127 |       for any such Derivative Works as a whole, provided Your use,
128 |       reproduction, and distribution of the Work otherwise complies with
129 |       the conditions stated in this License.
130 | 
131 |    5. Submission of Contributions. Unless You explicitly state otherwise,
132 |       any Contribution intentionally submitted for inclusion in the Work
133 |       by You to the Licensor shall be under the terms and conditions of
134 |       this License, without any additional terms or conditions.
135 |       Notwithstanding the above, nothing herein shall supersede or modify
136 |       the terms of any separate license agreement you may have executed
137 |       with Licensor regarding such Contributions.
138 | 
139 |    6. Trademarks. This License does not grant permission to use the trade
140 |       names, trademarks, service marks, or product names of the Licensor,
141 |       except as required for reasonable and customary use in describing the
142 |       origin of the Work and reproducing the content of the NOTICE file.
143 | 
144 |    7. Disclaimer of Warranty. Unless required by applicable law or
145 |       agreed to in writing, Licensor provides the Work (and each
146 |       Contributor provides its Contributions) on an "AS IS" BASIS,
147 |       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
148 |       implied, including, without limitation, any warranties or conditions
149 |       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
150 |       PARTICULAR PURPOSE. You are solely responsible for determining the
151 |       appropriateness of using or redistributing the Work and assume any
152 |       risks associated with Your exercise of permissions under this License.
153 | 
154 |    8. Limitation of Liability. In no event and under no legal theory,
155 |       whether in tort (including negligence), contract, or otherwise,
156 |       unless required by applicable law (such as deliberate and grossly
157 |       negligent acts) or agreed to in writing, shall any Contributor be
158 |       liable to You for damages, including any direct, indirect, special,
159 |       incidental, or consequential damages of any character arising as a
160 |       result of this License or out of the use or inability to use the
161 |       Work (including but not limited to damages for loss of goodwill,
162 |       work stoppage, computer failure or malfunction, or any and all
163 |       other commercial damages or losses), even if such Contributor
164 |       has been advised of the possibility of such damages.
165 | 
166 |    9. Accepting Warranty or Additional Liability. While redistributing
167 |       the Work or Derivative Works thereof, You may choose to offer,
168 |       and charge a fee for, acceptance of support, warranty, indemnity,
169 |       or other liability obligations and/or rights consistent with this
170 |       License. However, in accepting such obligations, You may act only
171 |       on Your own behalf and on Your sole responsibility, not on behalf
172 |       of any other Contributor, and only if You agree to indemnify,
173 |       defend, and hold each Contributor harmless for any liability
174 |       incurred by, or claims asserted against, such Contributor by reason
175 |       of your accepting any such warranty or additional liability.
176 | 
177 |    END OF TERMS AND CONDITIONS
178 | 
179 |    APPENDIX: How to apply the Apache License to your work.
180 | 
181 |       To apply the Apache License to your work, attach the following
182 |       boilerplate notice, with the fields enclosed by brackets "[]"
183 |       replaced with your own identifying information. (Don't include
184 |       the brackets!)  The text should be enclosed in the appropriate
185 |       comment syntax for the file format. We also recommend that a
186 |       file or class name and description of purpose be included on the
187 |       same "printed page" as the copyright notice for easier
188 |       identification within third-party archives.
