joinEnv - Just like joinPath but with ; for windows else :

[solvingj]

Description

Title basically says it all. Once it's possible to prepend paths to the PATH via env (ideally fixed in #2034) , it should have a native cross-platform syntax for doing it cleanly on windows or posix platforms.

env:
    PATH: "{{joinEnv "{{.TASKFILE_DIR}}/tools/bin" .PATH}}"

or perhaps

env:
    BIN_DIR: "{{joinPath {{.TASKFILE_DIR}} "tools" "bin"}}"
    PATH: "{{joinEnv .BIN_DIR .PATH}}"

Additionally, or alternatively, add a special variable: PATHSEP for platform specific path separation in env vars.

env:
    PATH: "{{{{.TASKFILE_DIR}}/tools/bin{{.PATHSEP}}{{.PATH}}"

This sounds like an easy one. Open for community pull requests.

Happy with this too. A couple of implementation notes:

• Separators
  • Windows uses ;
  • Linux/MacOS use :
• I think there is no harm in a "join" function and a variable being added.
• PATHSEP is highly ambiguous. Something like PATH_ENV_SEPARATOR
  • I prefer clarity over short names
  • _ as a word separator in var names
• Same for joinEnv. This should be something like joinPathEnv
  • Same reasons for naming as the variable
  • Naming lines up with the variable
• We don't actually have a FILEPATH_SEPARATOR
  • This could be added for parity
  • Add both to the templating reference docs under system variables.

Agh... there's a func in there defined as os() which breaks importing os.PathListSep. How you want me to deal with it? Rename os()/arch() to goos()/goarch() perhaps?

I'm interested in working on this issue. Could you provide more context about what you're looking for? Any additional details about requirements or constraints would be helpful.

Thanks but the work is done. The implementation details were essentially obvious and confirmed by @andreynering and @pd93 . It's just a matter of them finding time to review and merge.
