Universal Canvas LMS CLI

Canvas's web UI is the only first-class surface for most students and instructors. That's fine until you want to check grades from a terminal, batch-download course files, script your weekly to-do, or pipe submission data into something else. The official REST API exists, but writing curl invocations by hand is friction nobody wants in their day.

A small, focused Go binary that wraps the Canvas REST API behind ergonomic subcommands. Authentication is a single API access token, configured once with `canvas-cli configure` and stored at `~/.canvas-cli/config.json` with `0600` permissions. Every command takes `--json` so output composes with `jq`, `xargs`, or any pipeline. No external Go dependencies — only the standard library.

1. 01
   Token-only auth
   No SAML dance, no browser handshake. Paste your token once and the CLI is ready. Generate it from Account → Settings → New Access Token in any Canvas UI.
2. 02
   Universal
   Works against any Canvas LMS instance — university, K-12, or self-hosted — because it speaks the public REST API and nothing else.
3. 03
   Composable
   Every command supports `--json` and `--per-page`. Output flows naturally into `jq`, `xargs`, or whatever automation you already trust.
4. 04
   Zero external deps
   Pure Go standard library. Distributed as a single static binary — no runtime to install, no virtualenv to remember.
5. 05
   20+ commands
   courses, assignments, grades, submissions, submit (text or URL), todo, upcoming, missing, calendar, modules, discussions (with --reply), announcements, files, download, notifications.
6. 06
   Built for daily use
   Color-coded output, human-readable tables, sensible defaults. `canvas-cli todo` and `canvas-cli grades` are the commands you'll actually run every morning.
