ORMOLU(1)

💖 ORMOLU 💖

okay bestie, so this is the manual page for ormolu — it's a User Commands situation, section 1 of the manual, and it's literally about ormolu version 0.7.7.0. it's a Haskell source formatter and it's giving main character energy, no cap. let's get into it 🫶

---

✨ NAME ✨

ormolu — manual page for ormolu 0.7.7.0 💅

---

🌸 SYNOPSIS 🌸

ormolu [-v|--version] [--manual-exts] [-i | (-m|--mode MODE)]

---

🦋 DESCRIPTION 🦋

so like, here's the rest of the synopsis, it's a long one, stay with me:

       [-o|--ghc-opt OPT] [-f|--fixity FIXITY] [-r|--reexport REEXPORT]
       [-p|--package PACKAGE] [-u|--unsafe] [-d|--debug]
       [-c|--check-idempotence] [--color WHEN] [--start-line START]
       [--end-line END] [--no-cabal] [--no-dot-ormolu]
       [--stdin-input-file ARG] [-t|--source-type TYPE] [FILE]

that's it that's the whole vibe. now the options, which are the actual ✨content✨.

🎀 Available options:

• -h, --help — Show this help text 🙏 like literally the thing you're reading rn
• -v, --version — Print version of the program 👑 gotta know what you're working with
• --manual-exts — Display extensions that need to be enabled manually 👀
• -i — A shortcut for --mode inplace ⚡ it's the glow-up button, it rewrites your file right there
• -m, --mode MODE — Mode of operation: 'stdout' (the default), 'inplace', or 'check' 🍓 so stdout is the default bestie, inplace edits the file, check just... checks
• -o, --ghc-opt OPT — GHC options to enable (e.g. language extensions) 🧚
• -f, --fixity FIXITY — Fixity declaration to use (an override) 💅 an override, so it wins
• -r, --reexport REEXPORT — Module re-export that Ormolu should know about 🌈
• -p, --package PACKAGE — Explicitly specified dependency (for operator fixity/precedence only) 💜 note the parenthetical, it's only for operator fixity/precedence, don't get it twisted
• -u, --unsafe — Do formatting faster but without automatic detection of defects 💀 yeah so it's faster but it stops checking for defects, choose wisely
• -d, --debug — Output information useful for debugging 🔥
• -c, --check-idempotence — Fail if formatting is not idempotent 😭
• --color WHEN — Colorize the output; WHEN can be 'never', 'always', or 'auto' (the default) 🌸 yes auto is the default, it just figures it out
• --start-line START — Start line of the region to format (starts from 1) ⭐ note that it starts from 1, not 0, we are not doing zero-indexing today
• --end-line END — End line of the region to format (inclusive) 🫶 inclusive!! so it includes that line
• --no-cabal — Do not extract default-extensions and dependencies from .cabal files 🙈
• --no-dot-ormolu — Do not look for .ormolu files 🎀
• --stdin-input-file ARG — Path which will be used to find the .cabal file when using input from stdin 💖 v specific, v useful
• -t, --source-type TYPE — Set the type of source; TYPE can be 'module', 'sig', or 'auto' (the default) ✨ again, auto is the default, she's flexible like that
• FILE — Haskell source files to format or stdin (the default) 👑 so you can pass files, or just pipe it in from stdin, which is the default
