Having a trail of your coding flow can be handy or will explain the longing question about 'what was i thinking' when resolving problems of https://adventofcode.com/

Warning: this script needs Rust (unfortunately) installed

#!/usr/bin/env bash
### File : watcher.bash
### Location : somewhere outside project dir
### Install : `cargo install cargo-watch`
### Then run : `cargo watch --shell ../watcher.bash`
echo "===== watcher.bash ====="
echo ""
# Show user updates
git status
# Add files in the source directory
git add src
# Make sure other files already in the repo to get added during this commit.
git commit -am "`date +%Y-%m-%dT%H:%m`"

More sugar

Add this to the end of the file to make your Rust code clearer

# Format code after commit to inform the user (trusting his/her editor)
cargo fmt
cargo build
if [ $? -eq 0 ]
then
 cargo test
 if [ $? -eq 0 ]
 then
 # Run your project
 exec cargo run
 else
 echo "Test failed"
 fi
else
 echo "Build failed"
fi
echo "----- done -----"
exit 0
