SourceTree- VBA Macros via xltrail

jkeeney

I have been developing some VBA Macros in Excel and I would like to use revision control to help manage the development.

I have discovered https://www.xltrail.com/client which is an open source Git command line extension: git-diff and git-merge.

It seems to work great from the git command line. However, I am used to using SourceTree. Anyone know how I can merge these two together?

Under git I tried system git instead of embedded. I also tried playing around with the external diff/merge options. I couldn't seem to get it right.

xltrail added the following to my .git/config file if this helps.

[diff "xltrail"]
command = git-xltrail-diff.exe
[merge "xltrail"]
name = xltrail merge driver for Excel workbooks
driver = git-xltrail-merge.exe %P %O %A %B

I am a beginner with Git and SourceTree. Any help would be greatly appreciated.

Hello! Sourcetree doesn't currently support doing this as we explicitly disallow external diff drivers for specific file types. However, I don't see why we couldn't support this as it's a pretty small change for us to make.

For what it is worth, that would be a huge help to me.

SourceTree is a critical part of my development for all of the other languages I code in. Being able to use SourceTree for my VBA development would be a huge win.

I still use it, but not being able to use diff and merge limits its usefulness.

Thanks for considering this!

Hey, just wanted to throw my support in for this as well! It would be so nice to be able to use xltrail + Sourcetree's diff viewer.

Just to provide an update on this one -- it's going to take a bit longer than expected due to xltrail not producing a standard git diff:

It ignores most diff command switches such as color formatting and mnemonicprefix
It outputs as if there are multiple files (which is OK), but doesn't add an additional diff header

Thanks for your patience!

Thanks for the update!

Not trying to hold you to anything. However, do you have an idea if this might be on the order of weeks, months, etc.?

Mike Corsaro

Probably in the 2.7 release, which will be coming in the next few weeks.

Daniel Shunfenthal

A couple weeks is pretty good, thanks!

Should those issues be brought up to them? Or do you think you can handle it on your end?

As an aside, I would've thought color formatting is handled by SourceTree?

Hi @Mike Corsaro I am one of the maintainers of git-xltrail. I see that it now works with SourceTree 3.0.12. However, I can only see it working in the case of uncommitted changes, not for already committed changes. Is there a simple reason for why that is? We're happy to do changes on our side as per your suggestion but I was wondering if the current behaviour was expected. Thanks for a quick feedback!

I wrote a short blog post about how to use SourceTree with git-xltrail: https://dev.to/fzumstein/how-to-diff-excel-vba-code-in-sourcetree-git-client-36k

@Mike Corsaro @fzumstein What follows isn't technically an answer, but I figured it would make sense to keep a related beginner xltrail/sourcetree question in the same (and only similar) thread.

Along similar lines to OP I'm a relative beginner with Git, xltrail, and SourceTree, and I've been playing around with using these tools to manage some xlsm files.

Everything seemed to be working swimmingly, but I ran into some trouble when I edited a VBA module in one of my xlsm files and then observed it in Sourcetree.

When I try to stage or discard lines/hunk, I get the following error:

The content of that file is:

diff --git a/diff_results.xlsm b/diff_results.xlsm

--- a/diff_results.xlsm

+++ b/diff_results.xlsm

' Return code?

Call RunPowerShell(cmd, "CompareResults")

[31m-' dummy comment added

[32m+' dummy comment revised after being added

End Sub

Sub CallCompareResults()

I verified that I could discard hunk with a change to a simple text file, so I think my basic sourcetree and repo setup is right. Perhaps xltrail doesn't support patching like this? Or might something else be the problem?

Just to minimize confusion: We have renamed git-xltrail into Git XL and hence all commands are now "git xl" instead of "git xltrail". Everything else stays the same, but during upgrading it might be best to completely uninstall git-xltrail before you upgrade to git-xl.
