Formatter for IDL and Xtend

[dlime]

Hello! I'm facing this issue:
I have many IDL and Xtend files that I would like to include to the spotless auto formatter task.
I'm planning to define a custom XML file, similar to the Eclipse ones, in order to give formatting rules.

For now the only thing that I can do is this:

format 'IDL', {
    target '**/*.idl'
    trimTrailingWhitespace()
    endWithNewline()
}

I'm looking forward to do this:

format 'IDL', {
    target '**/*.idl'
    eclipse().configFile 'spotless.eclipseformat.xml'
    trimTrailingWhitespace()
    endWithNewline()
}

Right now this will throw the following error:

Could not find method eclipse() for arguments [] on object of type com.diffplug.gradle.spotless.FormatExtension.

Any ideas or suggestions for formatting non Java files with a custom XML file?

format 'language' only has generic formatters.

Language-specific formatters are only available in language-specific blocks, java {, groovy {, scala {, etc.

to fix your example, you could do:

java {
    target '**/*.idl'
    eclipse().configFile 'spotless.eclipseformat.xml'
}

But I'd be very surprised if the standard eclipse code formatter from JDT can also format xtend and IDL.

I think you'll probably need to create a new FormatterStep. You can do so in a separate project or in your buildscript, and we'd love a PR which includes your new features:

Thanks for suggestion! I was thinking to create my own XML file for formatting IDL/Xtend (I saw that I can define it with Checkstyle and then converting it to Eclipse)
I'll keep you updated:)
