ANSI colour escape codes crash argbash parser about argbash HOT 4 CLOSED

Actually, here's an even smaller reproducer:

#!/bin/bash
#
# This is a rather minimal example Argbash potential
# Example taken from http://argbash.readthedocs.io/en/stable/example.html
#
# ARG_OPTIONAL_SINGLE([option], [o], [optional argument help msg])
# ARG_OPTIONAL_BOOLEAN([print], , [boolean optional argument help msg])
# ARG_POSITIONAL_SINGLE([positional-arg], [positional argument help  msg], )
# ARG_HELP([The general script's help msg])
# ARGBASH_GO

# [ <-- needed because of Argbash


 local color_debug="\\x1b[35m"

# ] <-- needed because of Argbash

Looks like the parser doesn't like bash colour codes.

The square brackets in your script have to match (i.e. every opening square bracket [ has to be followed at some point by a closing square bracket ]).

There is a workaround — if you need constructs s.a. red=$'\e[0;91m', you can put the matching square bracket behind a comment, i.e. red=$'\e[0;91m' # match square bracket: ].

So you can simply add a comment as such

#!/bin/bash
#
# This is a rather minimal example Argbash potential
# Example taken from http://argbash.readthedocs.io/en/stable/example.html
#
# ARG_OPTIONAL_SINGLE([option], [o], [optional argument help msg])
# ARG_OPTIONAL_BOOLEAN([print], , [boolean optional argument help msg])
# ARG_POSITIONAL_SINGLE([positional-arg], [positional argument help  msg], )
# ARG_HELP([The general script's help msg])
# ARGBASH_GO

# [ <-- needed because of Argbash


 local color_debug="\\x1b[35m" #]

# ] <-- needed because of Argbash

Thanks for the reference. It's nice and all, but it doesn't solve the issue that I didn't know to look there when the parser crashed 👍

This is a technical limitation of the underlying technology. I know that this is a pain, and sorry for that, it is at least on the first page of the documentation under section Limitations.
