ERR_PARSE_ARGS_UNKNOWN_OPTION

Error message

Unknown error while parsing arguments

What it means

icongenie's get-argv wraps util.parseArgs for commands like `icongenie generate`/`profile`. On parse failure, __warn logs the full error, prints the parseArgs message for ERR_PARSE_ARGS_UNKNOWN_OPTION (unknown flag) or this generic fallback, and exits 1. This is icongenie's variant of the shared get-argv pattern across Quasar packages.

Solutions

1. Run `icongenie --help` or `icongenie generate --help` for the exact option list
2. Fix the typo or remove the unsupported flag (e.g. --qualty -> --quality)
3. Verify flags against current icongenie docs for your installed version
4. Quote paths/values containing spaces so tokens parse correctly

Example fix

// before
icongenie generate --qualty 90
// after
icongenie generate --quality 90

// check icongenie's accepted options before invoking
const { execSync } = require('node:child_process')
const help = execSync('icongenie generate --help').toString()
const flag = '--quality'
if (!help.includes(flag)) {
  throw new Error(`Flag ${flag} is not supported by 'icongenie generate'`)
}

When it happens

Trigger: Invoking icongenie with a flag not registered for that subcommand — e.g. `icongenie generate --qualty 90` (typo for --quality) or a profile-related flag on the wrong subcommand.

Common situations: Typos in long option names; reusing flags from `quasar dev` or other packages; stale flags from older icongenie versions documented in old tutorials; copy-paste errors that merge two flags together.
