Thought I would post this if anyone was interested. This is not on Package Control; I am only feeling out interest (if any). Though the core code is pretty stable, some of the new version control features can be considered beta.
There are a number of diff plugins available, so if there is no interest here, that is fine. I have been using the plugin for personal use for a while (though it is still evolving), and recently, after adding some new features, I thought I would offer it in its own repo to see if anyone other than myself would like to use this.
I have used a number of diff plugins (some very good), but all lacked what I wanted for the way I work...so, I wrote my own. This is not meant to allow merging, nor will it moving forward; just diffing. So let's get to the plugin:
EasyDiff is a plugin driven from the context menu (I found this more intuitive for the way I work). I wanted to quickly diff selections, multi-selection, clipboard comments, and files. Then overtime, I wanted to quickly diff files in my SVN repos and Git repos without having to go back to explorer or finder etc. I found the command palette too cumbersome, so I wanted to use the context menu. But when I selected something for the left side compare, I wanted to visually be able to see what was on the left side in case I got distracted and forgot. So EasyDiff solves this by creating a dynamic context menu in your user folder. When you pick a file for left side compare, the file name shows up in the context menu. Same with selections and clipboard.
Version control was a recent addition. I wanted to be able to see my current changes to be committed, or look at the diff of the last revision. And I wanted to be able to do this on the Git and SVN since I use them both. So EasyDiff has a wrapper around the git binary, and the svn binary (by default it assumes git and svn are in the PATH; you can point EasyDiff at the binary if you need to). I am sure someone will probably discover some small detail I have overlooked, but so far, they seem to work fine. If you don't use Git or SVN or either, you can selectively disable the menu items in the settings file. I will probably add Mercurial down the line; I just don't use it much.
Allows comparing views, selections, multi-selections, and clipboard combinations.
Dynamic context menus for selecting left side and right side compare. Dynamic menus show what file is on left
Compares current working copy against last committed revision in git and svn (must configure binary paths)
Shows diff of last commit in git and svn
Shows diff of staged commits for git
View diffs in a view buffer or output panel
You can selectively disable version control menus if you don't want to see them.
Feel free to tell me you like it, hate it, won't use it, make suggestions, or simply let this thread sink to the bottom of the feed.
