I was surprised when Travis failed to run my builds because Elixir isn’t supported - it is trivial enough to install the language tools via Chocolatey during the build without requiring explicit support.
In any case, this should be trivial to add, and would benefit a lot of community tools in Elixir that currently lack good Windows testing. Adding support is as simple as the following shell script:
choco install erlang choco install elixir export MIX_ENV=test export PATH=/C/ProgramData/chocolatey/lib/Elixir/bin:/C/ProgramData/chocolatey/bin:$PATH refreshenv
Here’s hoping we can get support soon!
