release tags may use `YYYY.MM.DD` -- for CLI tools, define a `USAGE` string constant at module level: - ```python - USAGE = """usage: tool [OPTIONS] - -h, --help show this help and exit - -V, --version show the current version and exit""" - ``` -- docstrings are lowercase, short, descriptive: - ```python - def derive_key(passphrase: str, salt: bytes) -> bytes: - """derive a 256-bit key from passphrase using scrypt""" - ``` -- error handling: print to stderr with "error:" prefix, then `sys.exit(1)`: - ```python - print("error: ciphertext too short to be valid", file=sys.stderr) - sys.exit(1) - ``` -- section comments to separate logical groups: - ```python - # config - # database - # helpers - # html templates - # request handler - # main - ``` -- use `if __name__ == "__main__": main()` pattern -- prefer simple type hints where helpful but don't over-annotate -- use `PyGObject` (`gi.repository`) for GTK3 systray and desktop applets -- security headers and input validation at system boundaries, not everywhere - - -Go Conventions --------------- -- single `main.go` for smaller tools is fine (kjagave is ~1000 lines in one file) -- constants grouped in a `const ()` block: - ```go - const ( - appTitle = "kjagave" - appVersion = "20260315-0200" - maxHistoryLen = 250 - ) - ``` -- structs are PascalCase, fields are PascalCase (idiomatic Go) -- methods on an `App` struct to organize state: - ```go - func (app *App) updateSchemePreview() { ... } - ``` -- error handling: check `err != nil`, use `log.Fatal` for unrecoverable errors -- config persistence with JSON (`json.MarshalIndent` with 2-space indent) -- prefer `os.ReadFile` / `os.WriteFile` over manual open/close - - -Commit Message Style --------------------- -- conventional-commit-like prefixes, all lowercase: - ``` - feat: add gitaur - refactor: ubuntu lts compat - refactor: clean-up non-stock highlight.js languages - refactor: change to 0BSD - initial: batman - ``` -- common prefixes: `feat:`, `refactor:`, `initial:`, `fix:` -- short, direct, no period at the end -- body is optional and rarely used - - -Project Structure ------------------ -- flat structure for small tools (script + README + LICENSE + Makefile) -- `src/` directory for the main source when there's more than one file -- Makefile for install/remove: - ```makefile - PREFIX ?= $(HOME)/.local - - install: - mkdir -p $(PREFIX)/bin - install -Dm755 src/tool $(PREFIX)/bin/tool - - remove: - rm -f $(PREFIX)/bin/tool - - .PHONY: install remove - ``` -- alternatively, `install.sh`/`uninstall.sh` scripts for more complex installs -- `.assets/` for screenshots, gifs, demo media -- Arch Linux packaging (`PKGBUILD`) when applicable -- AppImage builds for cross-distro binary distribution - - -README Style ------------- -- lowercase headings and prose (no title case) -- sections: what it does, features, dependencies, install, usage, license -- terse and honest - "this was an old high school project", "i made this in like 10 minutes" -- self-deprecating where appropriate - "simple and crappy web app" -- no badges, no fancy formatting - just markdown - - -General Principles ------------------- -- keep it simple - if it can be a single file, make it a single file -- use the right tool: shell for glue, python for apps, go for gui/performance, make for builds -- avoid over-engineering and premature abstraction -- security done right at boundaries (input validation, rate limiting, proper crypto) - but don't litter internal code with defensive checks -- config via environment variables for server apps; desktop apps use XDG config dirs (`~/.config/<app>/`) with JSON files -- date-based versioning (YYYYMMDD or YYYYMMDD-HHMM) -- use well-known, battle-tested crypto (aes-256-gcm, scrypt) - never roll your own -- sqlite for persistence when you need a database - - -Preferred Web Stack: V.P.S.
