How Can LabVIEW Projects Be Managed Using Git Tools?

Issue Details

• I have been using TortoiseSVN to manage my LabVIEW code, but am considering switching to Git. To what extent can LabVIEW projects be effectively managed using Git tools?
• I would like to better understand the different Git and CI/CD tools that can be used to manage my LabVIEW projects.
• What are the main benefits of using Git tools with my LabVIEW code?

Solution

Git is considered the most widely used distributed version control system, offering robust features for collaborative development, merging and integration with Continuous Integration and Deployment (CI/CD) pipelines. It is also increasingly supported in LabVIEW environments.

LabVIEW projects can be effectively managed using Git, as it provides supports for the following key features:

1. Version Control

   Git is able to track the changes made to LabVIEW files such as .vi, .lvproj and .ctl. Although these files are binary, Git can still maintain a complete history of modifications. 

2. Branching and Merging

   One of Git's biggest advantages is its powerful branching model. It can isolate new features or bug fixes in separate branches and merge them back into the main codebase when ready. For more information, refer to [External] Why Use Branches?

3. Visual Diff and Merge Tools

   LabVIEW provides tools like LVCompare and LVMerge, which allows user to visually compare and merge changes in .vi files. These tools can be integrated into Git workflows to handle binary file differences more effectively.

For instructions on how to use LVCompare, refer to Compare Two VIs in LabVIEW. For instructions on how to use LVMerge, refer to Configuring Source Control with LVMerge.exe.

4. CI/CD Integration

   Git repositories can be connected to platforms like GitHub Actions, GitLab CI, or Azure DevOps. This enables automated testing, building and deployment of LabVIEW applications.

Additional Information

For those interested in implementing CI/CD workflows with LabVIEW and Git, refer to LabVIEW Continuous Integration With Jenkins/GitHub. This resource explains how to visualize code differences during pull requests and integrate LabVIEW projects with platforms such as Jenkins and GitHub.
