Custom Action to create archive of modified files
Asked by Gabe Shackle:

I'm looking to create a custom action that will generate an archive file containing only the modified files within a specific commit. Here is the working git call:

```
git archive -o update.zip HEAD $(git diff-tree --no-commit-id --name-only -r COMMITID)
```

This works fine on the mac side and also when called directly from the command line but fails when called via a batch file. I suspect there is some kind of syntax issue specifically related to writing this call within a batch file but I'm unable to figure it out. The error generated is:

unknown option \`no-commit-id\`

I noticed that if I remove the no-commit-id and name-only options the error becomes:

fatal: path not found: $(git

Any help would be greatly appreciated!

```
setlocal enabledelayedexpansionset output=for /f "delims=" %%a in ('git diff-tree --no-commit-id --name-only -r %1^^') do ( set output=!output! "%%a" )git archive -o update.zip HEAD %output%endlocal
```

body: This doesn't work for the last commit. Let's say I merge some Release branch to Master and then I want to export all files that were merged. In a zip file I get full repository :/ But if I try to export some earlier commit, then I get just the files I need.

body: Here's a solution using 7zip with a Custom Action (Settings \> Custom Actions \> Add):

Menu caption: \> dist.zip

\[ \] Open in a separate window  
\[ \] Show Full Output  
\[X\] Run command silently

Script to run: X:\\Your\\path\\to\\7-Zip\\7z.exe

Parameters: a $REPO\\dist.zip $FILE

(Restart SourceTree after creation for the changes to take effect!)

This action works from the context menu for Unstaged Files and changed files in commits from the Log / History (even with multiple files / multiple commits selected) and will add those files to a "dist.zip" in the repo root. Just note that the file will not be deleted before adding files, so if you want to start from scratch, remember to delete the zip file first.

This has made it so much easier to update live systems with just the files that have changed, in projects where there's no build system involved. I wonder how I was able to live so long without it. :-)

body: Git native command do generate archive from one old commit to last commit:  

```
git archive -o c:/maj.zip HEAD $(git diff --name-only HASHONLINE HEAD)
```

comments: author: Seth
body: That is not a git command, it is a bash script using two separate native commands.


author: Baptiste Menadier
body: I may misunderstand something, but i don't understand how people update their project in production when using git as versioning tool without this command.

comments: author: Seth
body: Two options:

1) Deploy the entire project, not just differences

2) Use that command (or something similar) without SourceTree.


author: Gabe Shackle
body: I've created a Gist that has the Mac and PC versions of the export script: <https://gist.github.com/hereswhatidid/8876881>


author: Baptiste Menadier
body: Why is there no option to do it from sourcetree native commands ? We need it when pushing on production... What are the files modified since last release ?

comments: author: Seth
body: There is no way to do it from SourceTree native commands because there is no way to do it with git native commands.

You should be able to put the script in Gabe's answer in a script file, and run that script from a SourceTree custom action.


author: Seth
body: So to be clear, you are putting the command in a batch file, and you are going to run the batch file from SourceTree's custom action?
