Travis configuration of phpcs for only current commit files

Question

I am configuring phpcs in Travis.
In order to check PHP code standard on commit push with travis CI.

I am using following script

script:
- phpcs --standard=PSR2  $(find ./ -name '*.php')

But this script checks each .php file. I need Travis to check only the current committed files.

Does someone has any solution for this case? Thanks in advance.

What you could try is the following:

get last commit id: (How to get the last commit ID of a remote repo using curl-like command?)

git log --format="%H" -n 1

Then get files in last commit: (How to list all the files in a commit?)

git diff-tree --no-commit-id --name-only -r `git log --format="%H" -n 1`

You can see that previous command is used here. The first part before backtits needs a commit id to list files from. This commit id is found with the first command.

And then if you want only php files you can use grep :

git diff-tree --no-commit-id --name-only -r `git log --format="%H" -n 1` | grep .php

Output on one of my php project:

app/Http/Controllers/BarterController.php
app/Http/Controllers/HomeController.php
app/Talk.php
resources/views/profiles/index.blade.php
resources/views/talks/show-comments.blade.php

Simply replace your command $(find ./ -name '*.php') with the one I gave above and it should work. Your command would become the following:

phpcs --standard=PSR2 $(git diff-tree --no-commit-id --name-only -r `git log --format="%H" -n 1` | grep .php)
