Gdb

Gdb dashboard

https://github.com/cyrus-and/gdb-dashboard

https://github.com/cyrus-and/gdb-dashboard/wiki/Support-older-GDB-versions

GDB dashboard requires at least GDB 7.7 compiled with Python 2.7 in order to work properly.
If it is really impossible to use an up-to-date version, the following script will patch the dashboard and add the missing pieces (some features may suffer from this):

mkdir -p ~/.gdbinit.d/
wget 'https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=blob_plain;f=gdb/python/lib/gdb/FrameDecorator.py;hb=4bd8fc3a1362970d9800a263987af8093798338b' -O ~/.gdbinit.d/FrameDecorator.py
sed -i '1s/^/python gdb.COMPLETE_EXPRESSION = gdb.COMPLETE_SYMBOL\n/' .gdbinit
sed -i "s/gdb_breakpoint.temporary/None/g" .gdbinit
cat >>~/.gdbinit <<EOF
python
import imp
gdb.FrameDecorator = imp.new_module('FrameDecorator')
gdb.FrameDecorator.FrameDecorator = FrameDecorator
end
EOF

Git

Check trailing whitespaces when committing

Save this script as .git/hooks/pre-commit

#!/bin/bash

# Get `Git commit` file list
git diff --cached --name-only --diff-filter=ACM | while read file; do
    if [ -f "$file" ]; then
        file_type=$(file -b "$file")
        if echo "$file_type" | grep -q "text"; then
            has_trailing_whitespace=$(grep -n -E '[[:space:]]+$' "$file")
            # Exit and print line if there's trailing whitespace
            if [ -n "$has_trailing_whitespace" ]; then
                echo "Warning: $file has lines with trailing whitespace."
                echo $has_trailing_whitespace
                exit 1
            fi
        else
            continue
        fi
    fi
done

Ps. Although there are some defects, it can be used for the time being without any major issues. I tried to add it to the project using the ‘-f’ option in ‘git add’ but it didn’t succeed. However, manually adding it to the project seems to be fine as well. And it has only been tested in Git Bash on Windows.
