✨ Language-Aware Automatic Indentation #1918
Description
Description
It would be great if CodeEdit, given instructions from the language grammar in use for the open file, were able to automatically indent and outdent lines as you type based on accepted style standards. For example, an "if" statement, "for" loop, etc. in most languages would cause the following lines to be indented once, then the closing bracket or statement would be outdented to line up with the original "if" or "for" statement. This functionality should be adjustable by editing settings for the language and able to be disabled entirely for those that prefer manual indentation.
TextMate is a good example to look at for reasonable behavior. The language grammars it uses to handle this functionality are also plist files and very easy to read to see how it's being done. Some plugins also enable this behavior in VSCode, though it's implemented inconsistently there.
Alternatives Considered
Most editors use manual indentation, which I assume CodeEdit will eventually support. Right now it only supports tabbing in (and does at least maintain that indent), but you cannot shift+tab out or use command+[ or command+] to outdent/indent (respectively) lines or selected blocks. Manual indentation works, and should be an option for those who wish to indent in ways inconsistent with language standards, but is far slower than automatic indentation.

Screenshots
Here's an example of TextMate auto-indenting and outdenting a for loop in a shell script (bash). The second line is automatically indented to my configured tab stop, then once I finish typing "done" it outdents it to match for. This also works correctly if "do" is placed on its own line.
