Fish Shell Conventions

File Organization (in SMS repo: fish/.config/fish/)

  • •conf.d/ -- Config snippets loaded alphabetically; use numeric prefixes (00-, 20-, 50-) to control order
  • •functions/*.fish -- Autoloaded functions (one function per file, name must match filename)

Scripting Rules

  • •Use set -gx for global exports, set -l for local vars
  • •Prefer string builtins over sed/awk for string manipulation
  • •Use fish_add_path instead of manually editing PATH
  • •No POSIX-isms: no $(), no &&/||, use and/or/; and

Testing

  • •fish --no-execute <file> to syntax-check without running
  • •fish_indent to format fish scripts
