Examples of 50 | representing a project or community include using an official project e-mail 51 | address, posting via an official social media account, or acting as an appointed 52 | representative at an online or offline event. Representation of a project may be 53 | further defined and clarified by project maintainers. 54 | 55 | ## Enforcement 56 | 57 | Instances of abusive, harassing, or otherwise unacceptable behavior may be 58 | reported by contacting the project team at abrudz@aplcart.com. All 59 | complaints will be reviewed and investigated and will result in a response that 60 | is deemed necessary and appropriate to the circumstances. The project team is 61 | obligated to maintain confidentiality with regard to the reporter of an incident. 62 | Further details of specific enforcement policies may be posted separately. 63 | 64 | Project maintainers who do not follow or enforce the Code of Conduct in good 65 | faith may face temporary or permanent repercussions as determined by other 66 | members of the project's leadership. 67 | 68 | ## Attribution 69 | 70 | This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4, 71 | available at https://www.contributor-covenant.org/version/1/4/code-of-conduct.html 72 | 73 | [homepage]: https://www.contributor-covenant.org 74 | 75 | For answers to common questions about this code of conduct, see 76 | https://www.contributor-covenant.org/faq 77 | -------------------------------------------------------------------------------- /CONTRIBUTING.md: -------------------------------------------------------------------------------- 1 | # Contributing 2 | 3 | If something is missing or not right, please [submit an issue](https://github.com/abrudz/aplcart/issues/new/choose). 4 | 5 | You can also submit a pull request, especially against [table.tsv](table.tsv) — the really simple TSV file database: 6 | 7 | - `<`, `>`, `&`, `'`, and `"` are automatically escaped 8 | - rows are separated by line breaks 9 | - line breaks may be CR+LF or just LF 10 | - empty rows are ignored 11 | - trailing line break is optional 12 | - columns are separated by tabs (` `) 13 | - do *not* put a trailing tab at the end of any line 14 | 15 | ## Example entries from table.tsv 16 | 17 | |SYNTAX|DESCRIPTION|CLASS|TYPE|GROUP|CATEGORY|KEYWORDS| 18 | |------|-----------|-----|----|-----|---------|--------| 19 | | +Y |Conjugate ('Identity' if Y not complex)|Primitive|Monadic|Function|Scalar|Function|Mathematical|plus complex| 20 | |(+⌿÷≢)N|Mean of N|Tacit|Monadic Function| |Mathematical|average arithmeticmean| 21 | |(f⍤r)Y|Rank: f on or between trailing rank-r subarrays|Primitive|Monadic Function|Dyadic Operator|Function Application| jotdiaeresis rank paw| 22 | |X(f⍤r)Y|Rank: f on or between trailing rank-r subarrays|Primitive|Monadic Function|Dyadic Operator|Function Application| jotdiaeresis rank paw| 23 | |X⌷⍨∘⊂J|Items of X at positions J|Tacit|Dyadic Function| |Selection|index| 24 | 25 | You don't have to fill all the columns, but do try to maximise the number of keyword synonyms in the KEYWORDS column 26 | 27 | ### Notation for arguments and operands 28 | 29 | Note how arguments and operands are given short menmonic names, as follows: 30 | 31 | |NAME

APLcart seeks to answer *How do I…* questions.** 4 | 5 | APLcart is a searchable collection of over three thousand short APL phrases intended for both beginners and professionals, with content provided by the community. Knowledge of basic APL syntax is a prerequisite. 6 | 7 | APLcart can also be used for [exercising your APL skills](#quiz). 8 | 9 | See [APL Wiki](https://aplwiki.com/wiki/APLcart) for background and history. 10 | 11 | ## Usage 12 | 13 | *→ See also [the video introduction](https://dyalog.tv/Dyalog19/?v=r3owA7tfKE8).* 14 | 15 | ### Notes 16 | 17 | - APLcart is for finding out *how to do* things, not for finding out, for example, what a symbol means or what a system function does. Please use the language documentation for such purposes. 18 | 19 | - The site may take some seconds to load due to the information being processed by the browser. Once ready, it does not require internet access any more. 20 | 21 | - All code in APLcart assumes the latest version of Dyalog APL Unicode edition and system defaults, for example `⎕IO←1`, `⎕ML←1`, `⎕DIV←0`. 22 | 23 | - Entries are meant for copying and pasting to the extent possible. Therefore, many entries are more involved than what might appear as necessary. For example, *Cube root* is listed as `(*∘÷∘3)N` instead of the straight-forward `N*÷3`. This is so that `*∘÷∘3` can be copied and used in defining `CubeRoot←*∘÷∘3` which would not be possible with the simpler expression. 24 | 25 | ### Interface 26 | 27 | See [here](https://www.w3schools.com/tags/att_global_accesskey.asp#table2) how to use access-keys on your system. 28 | 29 | - Hit [here](https://aplcart.info) and start typing (access-key q — for _**q**uery_ — to re-focus) 30 | - Insert leading and trailing slashes to [use regex](https://aplcart.info?q=%2F\b11\b%2F) (access-key r ― for _**r**egex_ ― to toggle) 31 | - [Some entries](https://aplcart.info?q=(>)) have a ▸ which can be clicked to open example code in a sandbox 32 | - [Some entries](https://aplcart.info?q=(?)) have a ? which can be clicked to open online documentation 33 | - Hit [?](#usage) in the top left corner to access this documentation (access-key e — for _**e**xplain_) 34 | - Hit [×](https://aplcart.info?q=) at the end of the input field to clear it (access-key x — for _e**x**punge_) 35 | - Hit [#](https://aplcart.info?q=42) in the top right corner copy to the current query to the address bar and to your clipboard (access-key c — for _**c**opy_) 36 | - Hit :octocat:︎ in the bottom right corner to access APLcart's source-code on GitHub (access-key a — for _**a**plcart_) 37 | - Hit ♥︎ in the bottom right corner to donate to the author (access-key d — for _**d**onate_) 38 | - Hit [◐](https://aplcart.info?w) in the bottom right corner to cycle theme (access-keys b for _**b**lack_, g for _**g**rey_, w for _**w**hite_) 39 | - Hit the result list to enable movement keys for scrolling (access-key z) 40 | - Hit [the input field](https://aplcart.info) at the top to start a new query (access-key e — for _**q**uery_) 41 | 42 | ## Quiz 43 | 44 | You can use APLcart to exercise your APL skills by solving various types of tasks: 45 | 46 | * Writing a function for a given task 47 | * Explaining the purpose of a given function 48 | * Filling in an obscured symbol 49 | 50 | While APLcart does not feature checking of your answer (indeed, there can often be various answers to any given task), you can compare your answer to APLcart's. 51 | 52 | ### Interface 53 | 54 | See [here](https://www.w3schools.com/tags/att_global_accesskey.asp#table2) how to use access-keys on your system. 55 | 56 | - Hit [here](https://aplcart.info/quiz) and choose task type, and figure out the answer. You may want to use [an APL interpreter](https://aplwiki.com/wiki/Running_APL). 57 | - Hit the logo [⊆⌈](https://aplcart.info ) in the top left corner to go to the main APLcart page (access-key a — for _**a**plcart_) 58 | - Hit [?](#usage) in the top left corner to access this documentation (access-key e — for _**e**xplain_) 59 | - Hit one of the Reveal buttons to reveal APLcart's answer (there may be other correct answers) to that task 60 | - Hit one of the Next… buttons to proceed to the next task of that type 61 | - Hit :octocat:︎ in the bottom right corner to access APLcart's source-code on GitHub (access-key a — for _**a**plcart_) 62 | - Hit ♥︎ in the bottom right corner to donate to the author (access-key d — for _**d**onate_) 63 | - Hit [◐](https://aplcart.info?w) in the bottom right corner to cycle theme (access-keys b for _**b**lack_, g for _**g**rey_, w for _**w**hite_) 64 | 65 | The access keys for the Reveal and Next… buttons are the first letter of the second word on each button: 66 | 67 | * Writing a function for a given task: c to _reveal **c**ode_ and t for _next **t**ask_ 68 | * Explaining the purpose of a given function: p to _reveal **p**urpose_ and f for _next **f**unction_ 69 | * Filling in an obscured symbol: o to _reveal **o**bscured_ and q for _next **q**uest_ 70 | 71 | ## DuckDuckGo support 72 | 73 | DuckDuckGo allows you to search APLcart directly using the `!aplcart` bang. For example, [searching for `!aplcart 42`](https://duckduckgo.com/?q=!aplcart+42) redirects to APLcart. This also means that if you set your browser's default search engine to DuckDuckGo, you can search APLcart directly from your browser address bar by prefixing your search with `!aplcart`. 74 | 75 | ## Application Integration 76 | 77 | ### Browsers 78 | 79 | APLcart supports [OpenSearch](https://en.wikipedia.org/wiki/OpenSearch) and as such can be added as search engine on various browsers, including Safari, Edge, Firefox, and Chrome. 80 | 81 | ### Dyalog APL 82 | 83 | APLcart is supplied as the user command `]APLCart` and the API function `⎕SE.Dyalog.Utils.APLcart`. For information about the user command, enter `]APLcart -?`. The API function takes a query as right argument, and optionally `1` as left argument to return all columns (even hidden ones) from the database, rather than just the shown first 2. A full database dump can be done with `table←1⎕SE.Dyalog.Utils.APLcart''` 84 | 85 | ### Dyalog Windows IDE 86 | 87 | The Windows Dyalog IDE allows using an online search when F1 is pressed with the cursor on an unknown word: 88 | 89 | - Options ▸ Configure ▸ Help/DMX ▸ Use online help for non-Dyalog topics ▸ URL: `https://aplcart.info?q=%s` 90 | 91 | ### Dyalog RIDE 92 | 93 | RIDE allows adding a website to its menu bar: 94 | 95 | - macOS: Dyalog ▸ Preferences ▸ Menu, then below the `&Help` line, insert a line containing &APLcart =https://aplcart.info 96 | - other platforms: Edit ▸ Preferences ▸ Menu, then below the `&Help` line, insert a line containing &APLcart =https://aplcart.info 97 | 98 | You can now press Alt-Alt,a to launch APLcart. 99 | 100 | ## URL API ("permalinks") 101 | 102 | After clicking [#](https://aplcart.info?q=42) simply copy the current address from your browser's address bar to share the current query. Note that your current theme is intentionally not included, to avoid blinding the recipient. Note that the result for such a URL isn't permanent; it depends on APLcart's content at the time of usage. 103 | 104 | ### Manual construction 105 | 106 | After [aplcart.info](https://aplcart.info/) you can add `?` and the following options, separated by `&` if you want both a theme and a query: 107 | 108 | - [w](https://aplcart.info?w) select **w**hite theme 109 | - [b](https://aplcart.info?b) select **b**lack theme 110 | - [q=query](https://aplcart.info?q=query) prepopulate the _Tell me about_ **q**uery field 111 | 112 | For example, for a white interface looking for "find", use [aplcart.info?w&q=find](https://aplcart.info?w&q=find) 113 | 114 | ## Scope 115 | 116 | To answer *how do I* questions, APLcart currently searches over 3000 entries: 117 | 118 | - General syntax, like `name f←Y` 119 | - Primitives, like `!` 120 | - Control structures, like `:If` 121 | - Keywords, like `:Access` 122 | - System commands, like `)CLEAR` 123 | - System functions, like `⎕SIGNAL` 124 | - System constants, like `⎕A` 125 | - System operators, like `⎕R` 126 | - System variables, like `⎕IO` 127 | - GUI objects, like `HTMLRenderer` 128 | - I-beams, like `819⌶` 129 | - Errors numbers and messages, like `11::DOMAIN ERROR` 130 | - User commands, like `]Box` 131 | - A selection of simple dfns, dops, and derived functions like `(0=|)` 132 | - All of dfns.dws, like `dfns.cal` (In APLcart, entries from here are prefixed `dfns.` . To use, insert `{(⍎⍵⎕NS⍬).⎕CY⍵}'dfns'` into your code, then call, for example, `dfns.cal`.) 133 | - Performance idioms from Dyalog's idiom list, like `{(+/∨\' '≠⌽⍵)↑¨↓⍵}` 134 | - Idioms from the APL2 idiom list, like `(+/|)` (fully updated to use modern APL) 135 | - James A. Brown's favourite idioms (fully updated to use modern APL) 136 | - All idioms from the FinnAPL idiom list, like `(⊢⍳⌈/)` (fully updated to use modern APL) 137 | - The Yale/APL79 idiom list (fully updated to use modern APL) 138 | - Selected entries from Dyalog's #onelinerwednesday series, like `(×/⊢÷+/-2×⊢)` 139 | - Adapted entries from JSoftware's Phrase Book (translated to APL) 140 | - and other entries [submitted](https://github.com/abrudz/aplcart/issues/new?assignees=abrudz&labels=addition&template=content-request.md&title=) by users like you! 141 | 142 | ## Features wish list 143 | - more links to TIO examples 144 | 145 | Got an idea for improving the site?
