chomp

chomp(str) removes trailing newline characters (\n, \r\n, and \r) from the end of a string. It does not affect newlines in the middle of the string.

Signature

chomp(str string) string

Example

Read a version file and strip the trailing newline before using it in a command:

computed "version" {
  description = "Application version from the VERSION file"
  expression  = chomp(file("VERSION"))
}

task "tag" {
  description = "Tag the current commit with the version"
  commands = [
    "git tag v${computed.version}",
    "git push origin v${computed.version}",
  ]
}

file("VERSION") reads the file contents including any trailing newline. chomp removes it so the version is clean for use in the git tag.

Notes

chomp removes only trailing newlines, not spaces or tabs. Use trimspace to strip all whitespace.
If the string does not end with a newline, it is returned unchanged.
