CADABRA(1)

💖 NAME 💖

okay so bestie, this is the CADABRA(1) page, and the whole vibe is field-theory motivated computer algebra system. The command is cadabra, and she is literally here to serve tensorial expressions. No cap. ✨

✨ SYNOPSIS ✨

cadabra

🔥 DESCRIPTION 🔥

Cadabra is a computer algebra system for the manipulation of tensorial expressions. That's the main character energy right there. 💅

The output of cadabra is either plain text or UTF8 encoded Unicode (peep the environment variables below 👀). The line-breaking properties of the latter are used to wrap large expressions at reasonable points. On top of the standard output, cadabra can print status information, which is wrapped in special <status>...</status> blocks. So if those show up, that's just the status girly popping in. 🫶

💅 OPTIONS 💅

• --silent — Disables all output, except for output generated by the @print algorithm. Like, shhh 🤫 but the @print algo still gets its moment.
• --loginput — Copy the input into the log file. Logging the input, periodt. 📝
• --input filename — Read the indicated file as input before switching to console input. So it's giving pregame with a file, then slide into console mode. 🎀
• --prompt string — Set the prompt of the interactive session to the indicated string. Customize that prompt vibe, bestie. ✨

🌈 ENVIRONMENT VARIABLES 🌈

The following variables toggle various features on or off, depending on whether the variable is set or not:

• CDB_PRINTSTAR — Display a star to indicate products. Without this setting, a space is used. So either a lil star ⭐ or a space, iykyk.
• CDB_USE_UTF8 — Use UTF8 encoding for output. This in particular will introduce non-breakable spaces to group objects together, as well as zero-width non-breakable spaces to prevent line-breaks after brackets, underscore and caret symbols. When this variable is not set, the output will be plain ASCII without any special symbols. UTF8 girlies stay winning 💖, ASCII besties keep it simple.
