docker-intellij-format

Docker container to run the IntelliJ formatter on your groovy files.

Usage

$ docker run --rm intellij-format -h
IntelliJ IDEA 2018.2.5, build IC-182.4892.20 Formatter
Usage: format [-h] [-r|-R] [-s|-settings settingsPath] path1 path2...
  -h|-help       Show a help message and exit.
  -s|-settings   A path to Intellij IDEA code style settings .xml file.
  -r|-R          Scan directories recursively.
  -m|-mask       A comma-separated list of file masks.
  path<n>        A path to a file or a directory.

Formatting your files

Use the --user option to preserve your files ownership and the --volume option to mount your current directory in the container.

• Format a single HelloWorld.groovy groovy file:

$ docker run --rm --user $(id -u):$(id -g) --volume $(pwd):/data intellij-format HelloWorld.groovy

• Format all the groovy files in the current directory recursively:

$ docker run --rm --user $(id -u):$(id -g) --volume $(pwd):/data intellij-format -r -m *.groovy .

Building the image

$ docker build -t intellij-format .

Code style settings

By default, the IntelliJ formatter will use the code style settings configured in the file groovy-code-style.xml.

This file can be generated directly from IntelliJ by following this documentation: Copying Code Style Settings

Since this code style settings file is copied during the build of the image, any modification to it must be followed by a re-build of the container to be applied. This mechanism allows for a versionning of the code style settings with the repository.
