ProcessPatches (gradle-patching 2020.10.08-4214 API)

com.brambolt.gradle.patching.tasks.ProcessPatches

Applies the unified diff patches found at patches and ending with the diffExtension (.diff by default) to the content at the content path and writes the results to the destination path.

The patch path can identify a file, in which case the content path must also identify a file and the diffExtension is ignored, or a directory in which case the content path must also identify a directory. If these paths identify files then the result will be a file with the same name as the content file, placed in the destination directory.

If patches and content are directories then the task will look for all patches with the diffExtension under the source directory, and apply the patches to files with the identical relative paths under the content directory.

In other words, the patches must be named the same as the content files, with the diff extension added. These match and produce the result:
```
     ${patches}/a/b/c/d/e.txt.diff
     ${content}/a/b/c/d/e.txt
     ${destination}/a/b/c/d/e.txt
 
```
When the patch task is applied with the structure given in the example above, the unified diff patch in e.txt.diff is going to be applied to e.txt, and this generates the file with the same name in the destination directory.
The diff utils library works on a line-by-line basis. The task therefore has to split the input files on newlines and recombine after patch processing. There is no attempt to produce exactly the same line endings. In particular, the output files will include always newlines before EOF, irrespective of whether the input data does or not.

- Property Detail
  - java.nio.charset.Charset charset
    
    The character set in use, UTF-8 by default.
  - java.lang.Object content
    
    The content to apply the patch(es) to. Can be a string path, a file object or a closure producing either.
  - java.lang.Object destination
    
    The directory (not file) to write the patched content into.
  - java.lang.String diffExtension
    
    The extension identifying the patch files. Set this property to a different value like .patch for example, to instruct the patching logic to look for files with an extension other than .patch.
  - java.lang.Object patch
    
    The patch to apply - syntactic sugar for using with single patches. Use either patch or patches, it does not matter which, if both are used then patch will be ignored.
  - java.lang.Object patches
    
    The patch(es) to apply. Can be a string path, a file object or a closure producting either.
- Method Detail
  - @org.gradle.api.tasks.TaskAction void apply()
    
    Applies the patches to the content.
  - @java.lang.Override org.gradle.api.Task configure(groovy.lang.Closure closure)
    
    Task configuration. If the processResources task is available then its destination directory is set as the default destination directory.
    Parameters:
    closure - The configuration closure
    Returns:
    The configured task
  - java.io.File findDefaultDestinationDir()
    
    Looks up the destination directory of the processResources task, if available, or returns null.
