Svn compare files

If you like what you are reading, please consider buying us a coffee or 2 as a token of appreciation. We are thankful for your never ending support. After preprocessing the input files, it runs the Linux tools meld, gvimdiff, tkdiff, or kompare on these intermediate files.

Amin I was just about to suggest the same when I saw your comment. I will not bore you with what has to be done with the second file.

Do any of these or any program offer both line level and word level merging in a graphic environment? Hey Aaron, thanks for the article. Do you have any benchmark comparing the software? I am asking because I use Meld and making a diff of a Mb SQL file just take forever, a little better if I turn off the syntax coloring but still take forever….

I mean, Kdiff3 is probably the best merge-tool available for any version control environment and I do use it roughly weekly. However, after using it for 10 years, I still find its GUI barely usable. I would describe it as best tool for file merging despite horrific GUI. It can even be run as stand-alone diff tool. It is available for all platforms. Have a question or suggestion?

Use just svn diff to display local modifications in a working copy. If a --revision -r option is specified in this scenario, though, it means:. By default, svn diff ignores the ancestry of files and merely compares the contents of the two files being compared. If you use --notice-ancestry , the ancestry of the paths in question will be taken into consideration when comparing revisions i. Compare BASE and your working copy one of the most popular uses of svn diff :. If you want to see the difference between two revisions which are already committed, use the Revision Log dialog and select the two revisions you want to compare using the usual Ctrl -modifier.

Then select Compare revisions from the context menu. If you did this from the revision log for a folder, a Compare Revisions dialog appears, showing a list of changed files in that folder. If you want to see the changes made to all files in a particular revision in one view, you can use Unified-Diff output GNU patch format.

This shows only the differences with a few lines of context. It is harder to read than a visual file compare, but will show all the changes together. From the Revision Log dialog select the revision of interest, then select Show Differences as Unified-Diff from the context menu. If you want to see the differences between two different files, you can do that directly in explorer by selecting both files using the usual Ctrl -modifier.

If you want to see the differences between a file in your working copy, and a file in any Subversion repository, you can do that directly in explorer by selecting the file then holding down the Shift key whilst right clicking to obtain the context menu. You can do the same thing for a working copy folder. TortoiseMerge shows these differences in the same way as it shows a patch file - a list of changed files which you can view one at a time.

If you want to see not only the differences but also the author, revision and date that changes were made, you can combine the diff and blame reports from within the revision log dialog. The built-in tools supplied with TortoiseSVN do not support viewing differences between directory hierarchies. But if you have an external tool which does support that feature, you can use that instead.

If you have configured a third party diff tool, you can use Shift when selecting the Diff command to use the alternate tool. Sometimes in the life of a project you might change the line endings from CRLF to LF , or you may change the indentation of a section. Unfortunately this will mark a large number of lines as changed, even though there is no change to the meaning of the code. The options here will help to manage these changes when it comes to comparing and applying differences.

You will see these settings in the Merge and Blame dialogs, as well as in the settings for TortoiseMerge. Ignore line endings excludes changes which are due solely to difference in line-end style.

Ignore whitespace changes excludes changes which are due solely to a change in the amount or type of whitespace, e. Adding whitespace where there was none before, or removing a whitespace completely is still shown as a change. Ignore all whitespaces excludes all whitespace-only changes.

This dialog shows a list of all files which have changed and allows you to compare or blame them individually using context menu. You can export a change tree , which is useful if you need to send someone else your project tree structure, but containing only the files which have changed.

You will be prompted for a location to save the change tree. The button at the top allows you to change the direction of comparison. You can show the changes need to get from A to B, or if you prefer, from B to A. The buttons with the revision numbers on can be used to change to a different revision range.

When you change the range, the list of items which differ between the two revisions will be updated automatically. If the list of filenames is very long, you can use the search box to reduce the list to filenames containing specific text. Note that a simple text search is used, so if you want to restrict the list to C source files you should enter. There are many tools available for diffing text files, including our own TortoiseMerge, but we often find ourselves wanting to see how an image file has changed too.
