Language issues

Crystal isn't supported officially by Geany, so another close language has to be chosen instead. We have the choice of either Ruby or CoffeeScript, here are their pros/cons. You can switch from one to another by modifying ~/.config/geany/filedefs/filetypes.Crystal.conf.

CoffeeScript (default)

Configuration: [styling=Coffeescript] and lexer_filetype=CoffeeScript

• structs and enums can be collapsed
• heredocs are not highlighted (because JavaScript doesn't)
• macros syntax are OK
• methods and symbols aren't highlighted
• blue color for common methods and related keywords

Ruby

Configuration: [styling=Ruby] and lexer_filetype=Ruby

• supports heredocs
• macro syntax not well supported, and usually mess up the rest of the file
• struct can't be collapsed
• standard and custom types are highlighted the same

See the Geany Wiki for more information about this configuration.
