Ai Language Idioms

Language Idioms for AI Agents

❄️ Nix

• Infinite Recursion: Never use config.foo to define the enable condition for config.foo.
• Strings: Prefer lib.concatStringsSep over repetitive string interpolation for lists.
• Let Bindings: Keep let ... in blocks as close to their usage scope as possible.

🥟 Janet

• Immutability: Janet has both mutable (array, table, buffer) and immutable (tuple, struct, string) data structures. Be explicit about which you are using.
• Macros: Avoid macros unless absolutely necessary. Use higher-order functions (map, filter, reduce) first.
• Error Handling: Use (try ... ([err] ...)) instead of letting the script crash, especially in hey CLI tasks.

🐚 Zsh

• Scoping: Always use local for variables inside functions.
• Arrays: Use Zsh array syntax my_array=(a b c) and iterate with for item in "${my_array[@]}"; do.
• Conditionals: Prefer [[ ]] over [ ] for safe string evaluation.
