Setting System Variables (Environment Variables)

This page describes how to set a System Variable / Environment Variable in JuliaWin.

JuliaWin Base

The base script (See activate-juliawin-environment.bat) defines...

Variables for Juliawin internal use:

• juliawin_home = absolute path of base directory
• juliawin_bin = %juliawin_home%\bin
• juliawin_packages = %juliawin_home%\packages
• juliawin_userdata = %juliawin_home%\userdata
• juliawin_sh = %juliawin_packages%\git\bin\sh.exe, or %PROGRAMFILES<(x86)>%\Git\bin\sh.exe, or sh.exe relative to where git
• juliawin_activated = 1

Variables for internally wrapped programs:

• JULIA_DEPOT_PATH = %juliawin_userdata%\.julia
• CONDA_JL_HOME = %juliawin_packages%\conda
• PYTHON = set to empty by making use of %JULIA_DEPOT_PATH%\config\startup.jl (since cmd can't set empty variables)

Paths added to PATH:

• %juliawin_packages%\julia\bin
• %juliawin_packages%\curl\bin
• %juliawin_packages%\vscode

User Controlled System Variables

The user may edit userdata\startup.cmd or userdata\startup.bat as an auxiliary batch file to set the environment.
This allows the user to update the path, add more variables, or run any custom code required before launching Julia or other binaries. For the implementation, see https://github.com/heetbeet/juliawin/issues/64.
