Comparing the contents of two files in Sublime Tex

Question

I have two cloned repositories of two very similar open-source projects, which I have been working on in different instances in Sublime Text 2 to arrive at my desired result. Code from both of these projects was used. I have been using Git as version control for my project, but have not included the original projects. Thus, I would like to be able to quickly compare the contents of two files of the original project and compare the differences between them and my project.

I was hoping that Sublime Text 2 would have a "Compare File" feature, but I can't seem to find anything related to it in the settings or online. A third-party ST2 package to accomplish this task would also work well. Is such a task possible to do within the ST2 text editor?

Answer 1

UPDATE OCTOBER 2017 I never knew this feature existed in Sublime Text, but the interface appears to have changed slightly from the previous answer - at least on OS X. Here are the detailed steps I followed:

1. In the Menu Bar click File -> Open...
2. Navigate to the FOLDER that contains the files to be compared and with the FOLDER selected, click the Open button, this makes the FOLDERS sidebar appear
3. In the FOLDERS sidebar, click on the first file to be compared
4. Hold the Ctrl on Windows or ⌘ on OS X, and click the second file
5. With both files selected, right click on one and select Diff Files...

This opens a new tab showing the comparison. The first file in red, the second in green.

Answer 2

Compare Side-By-Side looks like the most convenient to me though it's not the most popular:

UPD: I need to add that this plugin can freeze ST while comparing big files. It is certainly not the best decision if you are going to compare large texts.

Answer 3

You can actually compare files natively right in Sublime Text.

1. Navigate to the folder containing them through Open Folder... or in a project
2. Select the two files (ie, by holding Ctrl on Windows or ⌘ on macOS) you want to compare in the sidebar
3. Right click and select the Diff files... option.
