parse-ipr
Project home

Even with IntelliJ, it is often convenient to have a shell (or a command prompt) so that you can launch your program with various parameters. However, to do that, you have to set the CLASSPATH variable correctly, I used to do this by writing a little shell script, but then you have to maintain it as you add/remove libraries. All of those add up to a lot of efforts.

This little tool makes this process painless by:

1. reading IntelliJ's .ipr file (which contains paths to all the important directories/jar files)
2. formatting the contents into ';' or ':' separeted CLASSPATH variable style, and then
3. printing that out to stdout (possibly into a few different formats for different flavors of shell.)

You can then write a little wrapper script to set the output to the variable. This last step usually depends on your environment and shell, but I have the following shell script:

#!/usr/bin/bash
eval $(java -jar parse-ipr.jar -sh "$@")

And the following alias:

alias parse-ipr=". ~/bin/parse-ipr"

With these, I only need to type "parse-ipr" in the directory that contains *.ipr and it sets the CLASSPATH variable correctly.

On Windows, you can do:

java -jar parse-ipr.jar -batch %* > ./tmp.bat
./tmp.bat

Cygwin users can use orthogonal -cygwin option to get CLASSPATH in the Unix format, such as:

eval $(java -jar parse-ipr.jar -sh -cygwin "$@")

Try java -jar parse-ipr.jar --help for the list of complete options.

Usage

When invoked without any argument, it assumes that a file with the .ipr extension is in the current directory.

If arguments are specified, they will be treated as directory names that contain *.ipr, or the name of the .ipr file.
