Hi Volodya,

Thank you, that was exactly the kind of “cleaner” solution I was looking for. Would be great to get documented for future reference J

local GIT_BRANCH = [ SHELL "git rev-parse --abbrev-ref HEAD" : strip-eol ] ;

local GIT_HEAD = [ SHELL "git rev-parse --short HEAD" : strip-eol ] ;

echo "Git branch $(GIT_BRANCH) @ $(GIT_HEAD)" ;

Outputs:

Git branch develop @ 77f43d5

BR,

Martin

Could you try:

    local GIT_BRANCH = [ SHELL "git rev-parse --abbrev-head HEAD" : strip-eol ] ;

I'll get this documented.

I ended up with this, which seems to work as expected.. Thanks for pointing me in right direction, I thought it was a bug that linefeed was captured.

local GIT_BRANCH = [ SHELL "git rev-parse --abbrev-ref HEAD | tr -d '\n'" ] ;
echo "before$(GIT_BRANCH)after" ;

BR,
Martin
