Command Syntax

treemand <cli> [flags]
treemand version
treemand cache [clear|list]

Global Flags

Subcommands

version

Print version, git commit, and build date.

treemand version
# treemand v0.3.0 (abc1234) built 2026-01-01

cache

Manage the discovery cache (~/.treemand/cache.db).

treemand cache list           # List cached entries with age and size
treemand cache clear <cli>    # Remove one CLI's cached entry
treemand cache clear          # Remove all cached entries

Output Formats

treemand supports three output modes. The default is a colored tree for terminals; JSON and YAML are intended for scripting, diffing, and tool integration.

treemand git                     # colored text tree (default)
treemand --output=json git       # full tree as JSON
treemand --output=yaml git       # full tree as YAML (same structure)

JSON / YAML Schema

Both JSON and YAML output share the same structure:

{
  "name": "git",
  "description": "the stupid content tracker",
  "flags": [
    {"name": "--version", "value_type": "bool", "description": "Print version"}
  ],
  "positionals": [],
  "children": [
    {
      "name": "commit",
      "description": "Record changes to the repository",
      "flags": [
        {"name": "--message", "value_type": "string", "description": "Commit message"},
        {"name": "--all", "value_type": "bool", "description": "Stage modified files"}
      ],
      "positionals": [
        {"name": "pathspec", "required": false}
      ],
      "children": []
    }
  ]
}

Pipe JSON to jq for extraction:

treemand --output=json git | jq '.children[].name'       # list subcommands
treemand --output=json git | jq '.children[] | select(.name == "commit") | .flags[].name'

Tree Display Styles

treemand supports four presentation styles. In the TUI, press T to cycle through them; from the command line, use --tree-style:

default — icon-prefixed tree with inline flag pills

▼ git  the stupid content tracker
├── ▼ remote [--verbose]  Manage set of tracked repositories
│   ├── • add <name> <url>  Add a remote
│   └── • remove <name>  Remove a remote
├── • commit [--message=<string>, --all]  Record changes
└── • status [--short, --branch]  Show working tree status

columns — name · description alignment

  git                · the stupid content tracker
    remote           · Manage set of tracked repositories
      add            · Add a remote
      remove         · Remove a remote
    commit           · Record changes
    status           · Show working tree status

compact — maximum density (no icons, no flags)

  git
    remote
      add
      remove
    commit
    status

graph — classic tree connectors

└── git
    ├── remote
    │   ├── add
    │   └── remove
    ├── commit
    └── status

Non-Interactive Output

The default output is a Unicode tree with icons:

Use --icons=ascii for terminals without Unicode, or --icons=nerd for Nerd Font glyphs.

Interactive TUI (-i)

treemand -i git

What the TUI Does

The TUI lets you explore a CLI’s command tree and assemble a specific command interactively. The workflow:

1. Browse — navigate subcommands with ↓/↑ (or j/k)
2. Expand — press → to open a node; press again to enter children
3. Pick a command — press Enter to set it in the preview bar
4. Add flags — press f to open the flag picker, or Enter on a flag row
5. Fill positionals — press Enter on a positional to open an input prompt
6. Copy or run — press Ctrl+E to copy the assembled command or run it

The preview bar at the top updates live as you build the command.

Layout

┌─ ► git remote add ────────────────────────────────────┐
│   (live command preview — updates as you pick items)  │
└───────────────────────────────────────────────────────┘
┌─ Tree: git ───────────────┐┌─ Help: remote ───────────┐
│ ▼ git                     ││ Manage set of tracked    │
│   ▼ remote                ││ repositories.            │
│ ► • add <name> <url>      ││                          │
│   • remove <name>         ││ --verbose (-v)           │
│   • get-url <name>        ││   Be verbose             │
└───────────────────────────┘└──────────────────────────┘
  git remote add  [arrows]  ←:collapse  →:expand  H:help  q:quit

Keyboard Controls

Navigation

This matches the VS Code / macOS Finder tree model. To collapse a node and move to its sibling: press ← (collapse), then ↓ (next sibling).

Toggle navigation scheme with Ctrl+S (cycles: arrows → vim → WASD).

Tree Operations

Building Commands

View Controls

Mouse

Flags Modal (f)

Press f on any command node to open an interactive flag selector:

• Browse all flags for the current command (own + inherited)
• Search by typing to filter the flag list
• Press Enter on a boolean flag to add it directly
• Press Enter on a value flag (e.g. --message=<string>) to open an input prompt
• Already-added flags are marked with a checkmark

Positionals

When a command has positional arguments (e.g. git remote add <name> <url>), navigate to the positional row and press Enter to open an input prompt. The value is appended to the preview bar.

Caching

Discovery results are cached in an SQLite database:

treemand --no-cache docker           # skip the cache for this run
treemand cache list                  # show cached CLIs
treemand cache clear git             # clear one entry

Discovery Strategies

help (default)

Recursively runs <cli> --help / <cli> <subcmd> --help to build the tree. Falls back to <cli> help <subcmd>, man page lookup, and error output mining.

man

Parses the man page for the CLI (if available) using man <cli> and stripping groff formatting. Provides richer descriptions than --help for many Unix tools.

completions

Uses shell completion output (<cli> __complete, <cli> completion) to enumerate subcommands without executing --help for every node.

treemand -s help git          # default
treemand -s man git           # man page parser
treemand -s help,man git      # combine strategies, merge results

Configuration

treemand reads ~/.config/treemand/config.yaml or ~/.treemand/config.yaml:

icons: ascii          # unicode (default) | ascii | nerd
desc_line_length: 80  # max chars before description is truncated
stub_threshold: 50    # subcommand count before switching to stub nodes

colors:
  subcmd: "#5EA4F5"
  flag: "#50FA7B"

Precedence: CLI flags > environment variables > config file > defaults.
