If you are associated with a programming language (for example: through endorsement or being an internal contributor) you will not be able to add it unless you can prove its notability by citing multiple external sources that were not created with a conflict of interest.
The name of the file will be displayed as-is in the readme. It should be named according to the language it was written in. The name shouldn't be abbreviated too far (use JavaScript.js instead of JS.js) and it shouldn't be abbreviated too little (use CSS.css instead of Cascading Style Sheets.css). Additionally, use spaces instead of hyphens or underscores (use Objective C.m instead of Objective-C.m).
If a file name contains a special character that Windows is not able to display, substitute it with the following:
| Original | Substitute |
|---|---|
| / | ∕ |
| \ | ＼ |
| : | ˸ |
| * | ∗ |
| ? | ？ |
| " | ＂ |
| < | ﹤ |
| > | ﹥ |
| | | ❘ |
The code in the file should be the simplest and most straightforward way to print/display/show Hello World exactly once in the language used. User input should not be request and a newline should only be printed when necessary.
After adding the language file, run update_list.py with Python 3.6+ to automatically update the language list. If you don't have a local clone, you will need to increment the language count and alphabetically list the language yourself.
