bare-tui-paparam

A menu/form helper for any paparam CLI. Your tool already describes its whole surface in paparam — flags, args, subcommands, choices, defaults, descriptions. Add one line and mytool --menu drops the user into a filterable command picker, then a real terminal form for the command they chose, and finishes by handing you a result in the exact shape paparam's parse() returns.

              cmd.parse(argv, { run:false })   ← paparam validates; no runner fires
                      │
                      ▼
        onComplete(result, { argv })   ← result is paparam's parse() shape

The forms are generated from your real flag/arg metadata (a flag with .choices() becomes a picker, a boolean becomes a checkbox, defaults are prefilled, repeatables become editable lists). The argv it assembles is run through your own command with { run: false } — so paparam itself validates it (unknown flag, missing arg, bad choice, your own validate() checks) and yields the canonical result without executing your runner until you say so.

Built on bare-tui and bare-tui-form (forms from JSON Schema, rendered through its hardening).

Want AI assist?

Install the optional bare-tui-paparam-ai package. It re-exports everything here and adds:

• --find — type your goal in plain language; one AI call routes it to the right command, then shows that command's form.
• --hi — full agentic assist: the model curates which fields to ask and drip-feeds questions.
• AI-backed in-form help — press F1 / ctrl+k mid-form to ask a question.

Upgrading is a one-line import change — your --menu / runMenu code keeps working unchanged:

// before — no network
const { isMenuMode, runMenu } = require('bare-tui-paparam')
// after — AI tiers light up; menu code is untouched
const { isMenuMode, runMenu, isInteractiveHelp, runWithConfirm } = require('bare-tui-paparam-ai')

Install

npm install bare-tui-paparam bare-tui paparam

Runs on Bare

Quick start

const { command, flag, arg } = require('paparam')
const { isMenuMode, runMenu } = require('bare-tui-paparam')

const cmd = command(
  'run',
  arg('<link>', 'pear:// link or path to run'),
  flag('--store|-s [path]', 'storage path').default('./store'),
  flag('--mode|-m [mode]', 'how to run').choices(['terminal', 'desktop']),
  function run(c) {
    /* your real runner */
  }
)

if (isMenuMode(Bare.argv)) {
  // menu → pick a command → fill the form → confirm → run for real
  runMenu(cmd, { onComplete: (result, { argv }) => cmd.parse(argv) })
} else {
  cmd.parse(Bare.argv.slice(2)) // the normal CLI
}

Run it: bare mytool.js --menu. See examples/orbital-menu.js for a large multi-command tool exercising every field type.

Entry points

• isMenuMode(argv, flag = '--menu') → did the user pass --menu?
• menuHelp(command, opts) → run the menu TUI; resolves the MenuApp (read app.confirmed).
• runMenu(command, opts) → menuHelp + confirm + run-for-real (or your onComplete).
• buildMenuApp(command, opts, extras?) → construct a MenuApp without running the TUI (embedding / tests).

Options

• uiSchema — display hints per field ({ flag: { 'ui:widget': 'file' | 'directory' 'textarea' | 'password' } }). Path-like fields are auto-detected; this covers the ones a name/description doesn't reveal.
• validators — { <flag-or-arg name>: (value, { values }) => err | null }.
• validateSubmission — (result) => err | null, the final whole-submission gate.
• fieldHelp — { <flag-or-arg name>: 'a note' }. Drives the offline per-field help (F1 / ctrl+k shows the note for the focused field). You can also author these on the command itself with paparam's .hint('…').
• helpKeys — override the help keys (default ['f1', 'ctrl+k']).
• onComplete — (result, { argv }) => any, runs after the TUI exits instead of the default command.parse.
