Viewing Differences in Source Control Files—Perforce Helix Core

One of the benefits of Lingo's integrated source control is that you can view the history and differences for a particular file.

Ways to View Differences Between Files

You can view differences between files in the following ways:

• Two Versions of Same Source Control File (History/Roll Back) You can view code and content differences between two source control versions of the same file. This is useful if you need to roll back to an earlier version of a file. See Rolling Back to an Earlier Version of a File—Perforce Helix Core and Getting the Latest Version of Source Control Files—Perforce Helix Core.

  Example You have been working on translating a particular file for a few days. Each day you check out the latest version of that file from source control, make your changes, and check the file back in to source control at the end of the day. At a certain point, you determine that you need to "roll back" to an earlier version of the file, using it to replace the latest version. Therefore, you use this feature to view the highlighted differences between the current version and an older version of the file. Once you have identified the older version that you want to use, you can perform a "get" of that version.

• Local Versus Source Control Version of a File You can view code and content differences between the local version of a file and the source control version of that file.

  Example You check out a topic from source control and then make changes to some of the translations in your local copy of that file. You save your changes. Later that day, you want to revisit the new translations, but you cannot remember exactly which translations you added and which were there before. Therefore, you use this feature to highlight the text differences between your local version of the file and the version stored in the source control application. The new text is highlighted on the side displaying the local version of the file.
