Lamina PDF

invalid-command-line

All codes

  • Type: error
  • Kind: usage (the caller misused the API)

What happened

The command line didn’t parse: a command or flag laminapdf doesn’t have, a missing argument, a value of the wrong form, or - (standard input) named as more than one input.

Why

The CLI checks its whole command line before it reads any file, so a typo never runs half a command. Exit code 2 tells a script that the call itself was wrong, not the document.

How to fix

Run the command with --help to see its arguments, and laminapdf --help for the commands. Read standard input at most once per command.

Example

Terminal window
$ laminapdf info --pages 1 report.pdf
error[invalid-command-line]: unexpected argument '--pages' found


Usage: laminapdf info [OPTIONS] <INPUT>


For more information, try '--help'.
$ echo $?
2

With --json, the line on standard error has the message “the command line doesn’t parse” and the parser’s finding in data.detail.

Data fields

Which field is there depends on what was wrong:

  • detail: when the parser refused the line, the kind of problem it found, such as UnknownArgument or MissingRequiredArgument.
  • argument: when a value parsed but means nothing, the value given: the angle of pages rotate, a help topic or a --fields key (untrusted: caller text, never in the message).
