How to Combine Two Projects in Mercurial
If you’re working on multiple projects simultaneously, managing them effectively can become a challenge. You may find yourself wanting to combine two separate Mercurial repositories into one cohesive unit. This post walks you through the steps to merge these projects while keeping them organized in subdirectories, and it also discusses whether this is a good idea or not.
The Problem at Hand
You have two distinct Mercurial repositories and you believe that merging them makes sense for your workflow. This leads to two key questions:
- How do I merge the two projects?
- Is this a good idea, or should I keep them separate?
Merging repositories can streamline your development process, but it’s essential to understand the implications before diving in.
Step-by-Step Solution
Combining your two Mercurial repositories is a straightforward process when you follow these steps. Let’s break it down:
1. Clone One Repository
To start the merging process, you need to clone one of your existing repositories. This will serve as the base for your new combined repository. You can do this using the following command:
hg clone first_repository
2. Pull the Other Repository
Next, you’ll want to pull the content of the second repository into the cloned repository. This is done using the pull command with a crucial -f (force) flag, which allows pulling content from an unrelated repository. Here’s the command:
hg pull -f other_repository
Understanding the Force Flag
The -f flag is important in this case as it instructs Mercurial to ignore the fact that the two repositories are from different sources. This is what enables you to combine the content successfully.

Is Merging a Good Idea?
Before you commit to this merging process, consider the following factors:
- Project Interdependence: If your two projects are closely related or rely on each other’s code, merging can simplify management.
- Isolation: If the projects are distinctly separate, maintaining them as individual repositories might be beneficial for clarity and organization.
- Future Scalability: Think about how your projects may grow. Merging now could complicate things if you’re planning to expand either project significantly.
Ultimately, the decision to merge should align with your project’s needs and your workflow preferences.
Conclusion
Combining two projects in Mercurial can be a seamless process when you take the right steps. By cloning a repository and pulling content from another, you can create a unified project structure that helps streamline your development tasks. However, weigh the benefits and drawbacks to ensure that this merging approach truly meets your needs.
Remember, good repository management can lead to better productivity, and understanding the tools at your disposal is essential for any developer.
