Requires:

php >= 5.3

There are no other dependencies.

Install

composer global require davidrjonas/composer-lock-diff:^1.0

# With zsh, run `rehash` to make it known to the shell.

# try it
composer-lock-diff --help

If composer-lock-diff is not found, make sure ~/.composer/vendor/bin is in your $PATH env variable. For more information on how to do that see this question on Stack Overflow.

composer-lock-diff

Or from vim, to insert the output into the commit message, type :r!composer-lock-diff.

Options

--path, -p: Base to with which to prefix paths. Default "./"
--from: The file^, git ref, or git ref with filename to compare from (HEAD:composer.lock)
--to: The file^, git ref, or git ref with filename to compare to (composer.lock)
--md: Markdown table output
--json: json output
--pretty: pretty output when combined with --json (>=5.4 only)
--no-links: Don't include Compare links in plain text or any links in markdown
--only-prod: Only include changes from packages

Development

New features are always welcome! Follow these guidelines

Try to match the style of the code that already exists, even if it isn't your style (sorry!).
Make sure there is a way to test the feature.
Test with PHP 5.3 (I'm serious!), >=5.4<7, 7.current. Docker is helpful, particularly for the older versions. Just run the ubuntu:12.04 image and install php for 5.3 and 14.04 for 5.6. I can help if you're having trouble.

The Makefile has some test cases. Run make | less and inspect the output. If you need specific versions or more information, continue reading.

To run using the test data manually simply point the --to and --from args at the lock files,

php ./composer-lock-diff --from ./test-data/composer.from.lock --to ./test-data/composer.to.lock

Docker is very helpful for targeting a specific version of php and/or composer,

docker run --rm -it -v "$PWD":/src -w /src php:7.4.2 \
  php ./composer-lock-diff --from ./test-data/composer.from.lock --to ./test-data/composer.to.lock

Sometimes you want to test the git related functions. To do that first I make a temporary repo. Then I copy into it test-data/composer.from.lock as composer.lock to set the previous state and test-data/composer.to.json as composer.json for the future state. I commit those then run composer-lock-diff with the options I want to test and visually inspect the results.

mkdir tmp && cd tmp
git init
cp ../test-data/composer.to.json composer.json
cp ../test-data/composer.from.lock composer.lock
git add .
git commit -m "initial"

composer update
# or
docker run --rm -it -v "$PWD":/src -w /src composer:latest php composer update

php ../composer-lock-diff

# or, if you want to use docker, you'll need git
cd ..
docker run --rm -it -v "$PWD":/src -w /src php:7.4.2 bash
apt-get update && apt-get install -y git
# You may want composer as well,
curl -OL https://getcomposer.org/download/1.9.3/composer.phar
cd tmp
php ../composer.phar update
php ../composer-lock-diff

Add a test case to test-data/

Make a new, temporary git repo in ./tmp
Copy ../test-data/composer.from.json as composer.json and ../test-data/composer.from.lock as composer.lock.
Commit them.
Run composer install
Add your pre case to composer.json. Use an exact version.
Run composer update.
The generated composer.lock should look similar to ../test-data/composer.from.lock but there will be differences due to transient dependencies. No real way around that. Use composer-lock-diff to make sure none of the named packages change versions and your new case is there.
Copy composer.json to ../test-data/composer.from.json and composer.lock to composer.from.lock.
Copy ../test-data/composer.to.json as composer.json.
Add your post case to composer.json. Again, exact versions are best.
Generate a new lock file.
Use composer-lock-diff to test your feature.
When you're happy with it, copy composer.json to ../test-data/composer.to.json and composer.lock to ../test-data/composer.to.lock.

Test Cases

See Makefile.

comopser-lock-diff # no args
composer-lock-diff --from ./test-data/composer.from.lock --to ./test-data/composer.to.lock
composer-lock-diff --path ./test-data/
composer-lock-diff --from <git ref> # this gets tested with 'no args'
composer-lock-diff --from <git ref with filename>
composer-lock-diff --to <git ref>
composer-lock-diff --to <git ref with filename>
composer-lock-diff --only-dev
composer-lock-diff --only-prod
composer-lock-diff --no-links
composer-lock-diff --json
composer-lock-diff --json --pretty
composer-lock-diff --md
composer-lock-diff --md --no-links

If anyone can help test with Windows that would be very much appreciated!
