Contribute a wrapper script, When compare two git project, can read both .gitignore.

[zw963]

Ever I hope bc3 have function to support .gitignore, but I find a bc3 3.38 support -filters argument. it can be utilize to add git ignore list to bc3 filters list.

It not good, and not elegance, but enough. ; )

#!/bin/sh

filename=$(realpath -es "$@")
gitignore=$(echo "$filename" |xargs -d"\n" -n1 sh -c '[ -d "$@" ] && [ -s "$@/.gitignore" ] && echo "$@/.gitignore"' sh)
[ "$gitignore" ] && git_filter=$(IFS=$'\n' ; cat $gitignore |sort|uniq|sed 's/^/-/'|tr '\n' ';')
base_filter="-#*#;-*~;-.#*.*;-.git/;-.gitignore"
filter="$git_filter$base_filter"

BCompare -filters=$filter "$@"

saved as a script, named bc3 in your path.
