diff-to-html
Displays diffs in a convenient html page.
- Useful when dealing with large validation text files or directory structures in automated builds, e.g. on Jenkins.
- Collapsible diff sections for each file make the result easy to read when comparing directories
- Inline-diff (character-wise) helps you to easily identify changes (optionally line-wise)
- Pure Java solution
Example outputs:
Usage
Install:
$ ./gradlew installDist
To compare two directories (or files), e.g. dir1 and dir2, use the fat jar
$ java -jar build/libs/diff-to-html-1.1.jar dir1 dir2
or the start script
$ ./build/install/diff-to-html/scripts/diff-to-html dir1 dir2
which will give you something like

Directories differ!

-crlf,--ignore-line-endings ignore line endings, i.e. normalize CRLF /
LF while comparing files
-or,--only-reports always exits with zero
-iu,--ignore-unique ignore unique files
-de,--detect-encoding tries to determine encoding type
-u,--unified <arg> output <arg> (default 3) lines of unified
context
-fs,--max-size-diff <arg> no textual diff if file size differs too
much
-id,--line-diff generate line-wise diffs (default: inline /
character-wise)
