Grep xcov result into variable at fastfile - grep

Question

I'm using fastlane but I don't want to use xcov slack feature, I'm compiling all the info onto the same slack notification further sent.
lane :run_my_stuff do
xcov(project: "my-app.xcodeproj",
scheme: "my_scheme",
output_directory: "xcov_output",
only_project_targets: true)
$coverage=sh("grep \"(\d+.\d+\%)\"")
slack(message: "🍏",
success: true,
slack_url: "https://hooks.slack.com/services/xxxxxxxx...",
default_payloads: [],
link_names: true,
attachment_properties: {
fields: [{
title: "Coverage",
value: $coverage
}
]
})
end
This doesn't work but I believe it shows what I'm trying to achieve. I also tried to use:
$coverage=sh("cat xcov_report/index.html | grep '\d\+.\d\+\%' | head -1")

Answer 1

I figured out what was wrong w/ my code. Several things (sigh)
There is no need for dollar sign
coverage=sh("cat xcov_output/index.html | grep '\\d\\+.\\d\\+\\%' -o | head -1")
The folder in which I was wasn't the same I thought. So I changed the output path to fastlane/xcov_output
The escaping at the regular expression was not enough. So I doubled it
End
xcov(project: "my-app.xcodeproj",
scheme: "MOCK",
output_directory: "fastlane/xcov_output",
only_project_targets: true)
release_notes=sh("git tag -l --format='%(contents)' $(git describe $(git rev-list --tags --max-count=1))")
coverage=sh("cat xcov_output/index.html | grep '\\d\\+.\\d\\+\\%' -o | head -1")
slack(message: "🍏 b(#{number_of_commits}) <#XXXXX>",
success: true,
slack_url: "https://hooks.slack.com/services/...",
default_payloads: [],
link_names: true,
attachment_properties: {
fields: [
{
title: "Release notes",
value: release_notes
},
{
title: "Environment",
value: environment.capitalize
},
{
title: "Coverage",
value: coverage
}
]
}
)
