This is a Zsh plugin that reminds users to use defined aliases when they type a command that has an alias. It hooks into Zsh's preexec and precmd mechanisms to intercept commands, expand them, and compare against all defined normal, global, and git aliases. If a match is found and the user did not use the alias, it prints a configurable reminder message (before or after command execution). It also supports a 'hardcore' mode that prevents command execution if an alias exists, forcing the user to use it. The plugin is a single Zsh script sourced into the user's shell, with no external dependencies other than Zsh 5.1+ and optionally `tput` for colored output. It provides toggle functions (`disable_you_should_use`/`enable_you_should_use`) and a report function (`check_alias_usage`) to analyze history and show alias usage counts. The code is well-structured, includes a comprehensive test suite using zunit, and handles edge cases like sudo commands, alias chains with cycle detection, ignored aliases, and multiple display modes.
The LLM identified 1 files worth highlighting for reuse:
The `_typed_resolves_to_alias` function implements a traversal of the Zsh alias chain to check if a command typed by the user ultimately resolves to a given target alias. It uses a local associative array `visited_aliases` to detect and break cycles, preventing infinite loops. This is a clean, self-contained pattern that could be extracted and reused in any Zsh script that needs to resolve alias chains without infinite recursion.
