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:

{Edit Environment dialog}

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.
