`:` opens a vim-style command line. Every command is described once, in a typed table (name, the short form that still works, aliases, a `!`, its arguments and what it does), so parsing, completion and the help can never disagree. Short forms work as in vim (`:e`, `:vs`, `:q!`, `:x`), and a test checks that no typed name can mean two commands. Parsing turns a line into a typed Call, checking every argument against what the app offers (open documents, nodes, colors, styles, settings), or says what's wrong in words: the usage when an argument is missing, the choices when a word isn't one, "did you mean :fold?" for a typo. Documents and nodes match fuzzily (`:b gpl` finds Garden plans). While typing, a popup above the word lists what can finish it (command names by prefix, choices, files from the folders on disk, documents and nodes fuzzily), with Tab and Shift-Tab putting them in the line. Ghost text after the cursor comes from the history first, like fish's, then from the best candidate; → or Ctrl-e takes it. Up and Down browse the lines that start with what was typed. The line itself is a small input that steps over whole characters, accents and emoji included. The canvas example opens it with `:` and runs a handful of commands: :fold, :color, :border, :tag, :focus, :rename, :in (to an Inbox), :link, :unlink, :find, :version and :q.

cumulus
Brainstorm in the terminal: ideas as nodes on a 2D canvas, connected, folded and color-coded, across as many documents as you like. Vim keys first; the mouse works too. Runs on Windows and Linux.
Status: being built, one stage at a time. See DESIGN.md for the plan; this README grows with the app.
Build and run
You need Rust (rustup.rs). The exact version is pinned in
rust-toolchain.toml, and rustup installs it by itself the first time.
cargo build --release
The program is target/release/cumulus (cumulus.exe on Windows): copy it to
a folder on your PATH.
- Windows: nothing else to install. The
.execarries its own C runtime and runs on any Windows 10 or 11. - Linux (Void, Fedora…): build the same way. You can also build a static
Linux binary from Windows with
cargo linux: it lands intarget/x86_64-unknown-linux-musl/release/cumulusand runs on any distribution.
Keys
The plan for the everyday keys (all of them are in DESIGN.md):
| Keys | What they do |
|---|---|
hjkl |
move to the nearest node that way |
gh gj gk gl |
parent, next sibling, previous sibling, first child |
o O a |
new sibling below / above, new child |
i or Enter |
edit the title |
dd x |
delete the branch / just the node |
u Ctrl-r |
undo / redo |
za zf zi |
fold, auto-fold, focus |
+ - |
zoom in / out |
C M v |
connect, move, select |
<Space> |
the action menu |
: ? |
command line, help |
After the first key of a sequence (g, z, d, <Space>…), a popup lists
what can follow.
Development
cargo test # run the tests
cargo lint # clippy, treating warnings as errors
cargo fmt # format the code
While the app is being built, the examples try out each part:
cargo run --example canvas # the canvas, vim keys, which-key, :commands
cargo test show_canvas -- --ignored --nocapture # print it at each zoom, as text
