windows - How to make AppVeyor use different versions of Emacs? -

-



i want use different versions of emacs. think have build matrix feature. have searched around , cannot find how done.

i going use choco install packages. default version emacs24. emacs25 available via unofficial package.

i want install different versions of same software , run simultaneous builds.

here wishful attempt of (this doesn't work way):

matrix:   - emacs: "24"   - emacs: "25"  install:   - ps : switch($emacs){ "24" {choco install emacs} "25" {choco install emacs64} default {echo "emacs install fail"}}   - refreshenv  build_script:   - script

thanks in advance.

emacs environment variable (not local one). yaml syntax require environment tag before matrix. can create configuration in ui , press export yaml button if not sure. , not space between ps , :. other config good. here fixed one:

environment:   matrix:   - emacs: 24   - emacs: 25  install:   - ps: switch($env:emacs){ 24 {choco install emacs} 25 {choco install emacs64} default {echo "emacs install fail"}}   - refreshenv

side note: recommend throw "emacs install fail" instead of echo.
