Batch edit environment settings
You can change the environment variable values for build or run environments either for a particular project or globally for all projects in the Edit Environment dialog:
- To change values globally, select Change in the global environment preferences.
- To change values for a project, select Batch Edit in the project, build, or run environment settings.
Use the following syntax to enter environment variable names and values: <VARIABLE>=<VALUE>
.
To remove a variable value from the environment, enter the variable name. For example, TEST
sets the value of the TEST
variable empty when building or running the project.
To add a variable value to the environment, enter the variable name and value, separated by the equals sign. For example, the following line prepends the /opt/bin
folder to the existing PATH:
- On Windows:
PATH=C:\opt\bin;${PATH}
- On Linux:
PATH=/opt/bin:${PATH}
To add or remove several variables, place them on separate lines. The order is important. If you remove a value on a line, you cannot refer to it on the following lines. However, you can remove a value after you have referred to it on an earlier line.
To temporarily disable a variable, add a hash character (#) to the beginning of the line.
