💖 NAME 💖

okay so M2 is how you start Macaulay2, a software system for algebraic geometry research 🧚

🎀 SYNOPSIS 🎀

M2 [option ...] [file ...]

🌸 DESCRIPTION 🌸

Typing M2 literally boots up Macaulay2 💅 It's a software system built for research in algebraic geometry and commutative algebra, and it's giving pure research energy 🔥

✨ Options ✨

• --help — shows a quick help message and then exits 🙈
• --no-backtrace — prints no backtrace after an error 💀
• --copyright — displays the full copyright message 📜
• --no-debug — doesn't drop you into the debugger when there's an error
• --debug n — debugs warning message n by signalling an error
• --int — don't handle interrupts
• --notify — notifies you when files load during initialization and when command line arguments get evaluated 🔔
• --no-prompts — prints no input prompts, going full silent mode 🤫
• --no-readline — don't use readline
• --no-core — don't load the Core
• --no-threads — don't start any additional threads (or tasks)
• --prefix DIR — sets prefixDirectory to DIR 🗂️
• --print-width n — sets printWidth=n, and the default is your window width 🪟
• --script — as the first argument, the second argument gets treated as the name of a script 📝 It implies --stop, --no-debug, --silent and -q. See scriptCommandLine.
• --silent — no startup banner, no fanfare ✨
• --stop — exits on error
• --texmacs — starts a TeXmacs session mode 🧪
• --version — prints the version number and exits 🔢
• -q — don't load your init.m2 file or use packages from your home directory 🏠
• -E '...' — evaluates the expression '...' before initialization
• -e '...' — evaluates the expression '...' after initialization

📚 SEE ALSO 📚

The docs are available locally, starting at ${prefix}/share/doc/Macaulay2/Macaulay2Doc/html/index.html. The ${prefix} part gets replaced by whatever directory prefix was used when the package got installed 🧠 That directory is stored as the value of the Macaulay2 variable prefixDirectory, but honestly the best way to get to the docs is to run viewHelp inside Macaulay2 🦋

The home page for Macaulay2 is https://macaulay2.com/ 🌈
