awk-scss-mod.md

I'm trying to write a program that replaces a scss function call and doubles the input e.g.

input

.color {
  margin: spacing(1.5);
}

.test {
  margin: spacing(2) spacing(3);
}

output

.color {
  margin: spacing(3);
}

.test {
  margin: spacing(4) spacing(6);
}

This almost works

gawk '{
  line = $0
  if (match(line, /spacing\(/)) {
    print gensub(/spacing\(([0-9\.]+)\)/, "spacing(\\1 * 2)", "g", line)
  } else {
    print line
  }
}' ./test.scss > ./test2.scss
// test2.scss

.color {
  margin: spacing(1.5 * 2);
}

.test {
  margin: spacing(2 * 2) spacing(3 * 2);
}
  • Can you multiply by two rather than appending " * 2" to the match?
  • How can you run on all **/*.scss files and replace them?
