cross platform recipe

[choupaland]

Hi,

I try to do cross platform justfile

i find a way with this

shell_executor := if os_family() == "windows" { "powershell.exe -c" } else { "sh -c" }
#set windows-powershell := true # need on windows because never set by default powershell ...

build_execute := if os_family() == "windows" { "just _build_windows" } else { "just _build_linux" }
build:
  @echo 'Build start!';
  {{ build_execute }};
  @echo 'Build end!';


_build_windows:
  {{ shell_executor }} \
  Set-Variable -Name step -Value "build"; \
  echo "$step WINDOWS Begin!" ; \
  cd ./scripts/build/6uhrmittag ; \
  .\build.bat ; \
  echo "$step WINDOWS  end!";

_build_windows_cmd:
  {{ shell_executor }} \
  @echo off; \
  set step="build"; \
  echo '%step% WINDOWS Begin!' ; \
  cd ./scripts/build/6uhrmittag ; \
  .\build.bat ; \
  echo '%step% WINDOWS  end!';

_build_linux:
  {{ shell_executor }} \
  step="build"; \
  echo '${step} LINUX Begin!' ; \
  cd ./boilr_6uhrmittag/ ; \
  make build ; \
  echo '${step} LINUX  end!';

I need do to this condition for ALL my command
build_execute := if os_family() == "windows" { "just _build_windows" } else { "just _build_linux" }

is it the only way ?

Best regards.

can i do this?

build_execute := if os_family() == "windows" { "_build_windows" } else { "_build_linux" }
build:
  @echo 'Build start!';
  @just {{ build_execute }};
  @echo 'Build end!' ;

Unfortunately it is the only way at the moment. The feature that would make this easier, allowing to specify different recipes for different OSs, is blocked on #604. Sorry I don't have better news!

You could avoid the \ if you use shebang recipes:

_build_linux:
  #!/usr/bin/env sh
  step="build"
  echo '${step} LINUX Begin!'
  cd ./boilr_6uhrmittag/
  make build
  echo '${step} LINUX  end!'
