Syntax error on parseArger generated script

[DimitriGilbert]

I wanted to try your compiler on the script generated by my tool parseArger but unfortunatly, I get this error when trying to build :
Error: syntax error: expected ]to close conditional expression, found-. (line: 8, column: 39)

The command I use to build :
docker run -v .:/bunster ghcr.io/yassinebenaid/bunster:latest bunster build hello-world.sh -o hi

and the bash script I try to compile

#!/bin/bash

if [ -t 1 ]; then # Check if stdout is a terminal
	ncolors=$(tput colors 2>/dev/null)
	if [ -n "$ncolors" ] && [ "$ncolors" -ge 8 ]; then
		_has_colors=1
	fi

echo "$output"

to try it ./hello-world.sh Yassine --greet "Salam alaykum" --exclam

and if you want to generate the parsing code with parseArger

parseArger generate --output hello-world.sh --help-message "Hi" \
  --pos 'person "who to greet"' \
  --opt 'greet "how to greet" --default-value "Hello"' \
  --flag 'exclam "!"'

I am concious it might be very much an edge case but I like the idea of being able to compile my bash scripts !

Are there pit falls I should avoid for Bunster to work best ?

[yassinebenaid]

There is nothing wrong with your script or the commands you ran.

The issue is that bunster is in its early stages of development. Not all features in your script are supported.

To learn more about what features are supported by bunster, please read this document.

However, This is temporary. I'm doing my best to add support for all remaining features.

[DimitriGilbert]

No worries, you get my ⭐ , I want to see where this is going :)

best of luck in this
