Features
Syntax Highlighting
Full TextMate grammar covering all Winn syntax:
- Keywords (
module, def, end, if/else, switch, match, try/rescue, fn, for)
- String interpolation (
"Hello, #{name}!")
- Atoms (
:ok, :error)
- Operators (
|>, =>, <>, .., ==, etc.)
- Module names, function definitions, function calls
- Maps (
%{key: val}), tuples, lists
- Comments (
# comment)
- Block parameters (
do |x, acc| ... end)
Diagnostics (Linting)

Errors appear as red squigglies with messages in the Problems panel.
