• Discord : https://discordapp.com/
• Python 3.6 : https://www.python.org/downloads/

3. Dependencies

You'll need to have the following Python libraries installed in order to use these hook scripts. They can be installed with the pip install <libraryname> command-line command.

• subprocess library : pip install subprocess
• sys library : (included in Python)

4. Hook Scripts

4.1. Post-commit

4.1.1. What It Does

After a commit is made to the specified repository, this hook script posts a message to Discord server channel, which is specified through a webhook. The message contains the name of the repository, the revision number, the name of the user who committed, the commit message, and the changelist. The hook script will automagically truncate commit messages longer than 200 characters and changelists longer than 1700 characters in order to abide by Discord's maximum character limit of 2000.

4.1.2. Usage Examples

Below are a few examples of what the message looks like in multiple scenarios.

4.1.3. How To Use

1. In VisualSVN, open your repository's Properties page.

2. Navigate to the Hooks tab and double-click the "Post-commit hook" property.

3. Copy the contents of scr/post-commit.cmd and paste them into the hook dialog's text box.

4. Change pythonw_file_path to point to the location of pythonw.exe in your Python installation directory.

5. Download scr/post-commit.py, then change hook_script_file_path to point to the file path to which you downloaded post-commit.py.

6. Change reponame to the name of the repository as set in VisualSVN.

7. In your Discord server, create a webhook in the channel in which the commit messages should be posted, copy the URL, then change discord_webhook_url to that URL.

NOTE: The Python hook script will override any username and avatar you specify in the Discord webhook dialog. With that said, the script can easily be changed if you don't want it to do this.

8. Click OK to accept the changes in the hook dialog, then click Apply and OK to accept the changes in the Properties dialog.

9. Open post-commit.py in a text editor.

10. Change the value of reporootdir to point to the root directory in which your Subversion repositories are stored. Don't forget to use double-backslashes in the file path! Also, make sure there's a (double-)backslash at the end of the file path so the repository's full file path can be assembled correctly.

EXAMPLE: reporootdir = "Y:\\Repositories\\"

11. Change the value of svnlook to point to the location of svnlook.exe, which can be found in VisualSVN's installation directory.

EXAMPLE: svnlook = "C:\\Program Files\\VisualSVN Server\\bin\\svnlook.exe"

12. Optionally, change the value of botavatarurl to the URL of your own custom image to use for the avatar of the bot that'll post the commit message.

EXAMPLE: botavatarurl = "https://i.imgur.com/Pi5ICIR.jpg"

13. Finally, save and close the file and try out the hook with a test commit to the repository for which you configured it!
