README

See what packages have changed after you run composer update by comparing composer.lock to the the git HEAD.

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.

Usage

composer update
# don't commit yet!
composer-lock-diff

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

Options

• -h, --help: Print this message
• -p, --path: Base to with which to prefix paths. Default "./"
  E.g. -p app would look for HEAD:app/composer.lock and app/composer.lock
• --from: The file^, git ref, or git ref with filename to compare from (git: HEAD:composer.lock, svn: composer.lock@BASE)
• --to: The file^, git ref, or git ref with filename to compare to (composer.lock)
• --json: Format output as JSON
• --pretty: Pretty print JSON output (PHP >= 5.4.0)
• --md: Use markdown instead of plain text
• --no-links: Don't include Compare links in plain text or any links in markdown
• --only-prod: Only include changes from packages
• --only-dev: Only include changes from packages-dev
• --vcs: Force vcs (git, svn, ...). Default: attempt to auto-detect

^ File includes anything available as a protocol stream wrapper such as URLs.

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!
