Wed Sep 25 07:01:07 UTC 2024: ## New Mercurial Extension Allows for Dynamic Usernames Based on Directory

**[City, State] – [Date]** – A new Mercurial extension, “mercurial-dynamic-username,” allows developers to use different commit usernames based on the directory tree they are working in. This means you can commit as “John Smith” in projects under your ~/work directory and as “Johny” for code located in ~/hobby, all without having to manually change your username every time.

The extension is easy to install using pip: `pip install mercurial-dynamic-username`. Once installed, you configure it through your ~/.hgrc file, defining username-directory pairings within the [dynamic_username] section. For example, you could set the following:

“`
[dynamic_username]
.location = ~/work
.username = John Smith
.location = ~/hobby
.username = Johny
“`

The extension prioritizes the longest matching directory path. So, if your repository is located at ~/work/libs/veryimportant, it will use the “John Smith” username defined for ~/work, even though it’s also a subdirectory of the longer path /home/littlejohny/work.

The developer behind the extension notes that this approach currently overrides the default username specified in the [ui] section of your .hgrc file. While the extension doesn’t currently prioritize per-repository usernames, the developer is open to implementing this feature in the future.

This extension is a powerful tool for developers working on multiple projects with different identities or collaborating on projects with multiple contributors. The dynamic username functionality eliminates the need to constantly switch usernames, simplifying the commit process and ensuring consistent project attribution.

To learn more about the extension and its installation process, visit the project’s documentation on the Mercurial Wiki: [Link to Mercurial Wiki Page]. You can also find the latest development updates and contribute to the project on Heptapod: [Link to Heptapod Project Page].
