# Using the LabVIEW Compare Tool with Source Control Providers

Version:

A source control provider is a piece of third-party software that enables you to share files among multiple users, improve security and quality, and track changes to shared projects. You can use the LabVIEW Compare Tool to display the differences between the local copy of a selected file and the version in source control.

Before beginning this task, make sure the computer on which you are running LabVIEW includes a source control provider.

Complete the following steps to configure a source control provider to use the LabVIEW Compare Tool as the default application to compare two versions of a file:

1. Direct the source control provider to LabVIEW Compare.exe. By default, LabVIEW installs LabVIEW Compare.exe in C:\Program Files\National Instruments\[Product]\LabVIEW Compare.exe.
2. Enter arguments in the source control provider to configure LabVIEW Compare.exe to perform different operations. The following table lists available arguments.
Argument Description
-alias1 Changes the display name of the first file. You may consider changing the display name of the file if the filename is randomly generated. Specifying a meaningful display name helps you to keep track of the version of the file.
-alias2 Changes the display name of the second file. You may consider changing the display name of the file if the filename is randomly generated. Specifying a meaningful display name helps you to keep track of the version of the file.
-usePreferences Specifies whether to use the default settings in the LabVIEW Compare Tool. The value for this argument can be only TRUE or FALSE. If you do not use this argument, the tool uses the default settings.
-exclude Specifies the types of differences to ignore.
-newprocess Opens the comparison in a separate window.

For example, you can use the following command to configure the source control provider to use the LabVIEW Compare Tool.

"C:\Program Files\National Instruments\LabVIEW Comms x.x\LabVIEW Compare.exe" $1$2 -alias1 TestFile -usePreferences true -exclude Diagram.Comments -newprocess

where

• $1 and$2 are variables the source control provider defines for the paths to the files you want to compare.
• -alias1 TestFile changes the display name of the first file to TestFile.
• -usePreferences true uses the default settings in the LabVIEW Compare Tool.
• -exclude Diagram.Comments configures the tool to not detect or display differences of comments on the diagram.
• -newprocess opens the comparison in a separate window.
3. (Optional) Complete any remaining steps to configure the source control provider. For example, some source control providers allow you to specify comparison tools for particular file extensions. You can specify LabVIEW Compare.exe for files with the .gvi, .gmrd, .gcdl, and .lvtype extensions. Consult the documentation for the source control provider for more configuration information.
