trimspace

trimspace(str) removes all leading and trailing whitespace characters from str, including spaces, tabs, and newlines.

Signature

trimspace(str string) string

Example

Read a project name from a configuration file and strip any accidental whitespace before using it in commands:

computed "project" {
  description = "Project name from the config file"
  expression  = trimspace(file(".project"))
}

task "build" {
  description = "Build the Docker image with the project name"
  commands = [
    "docker build -t ${computed.project}:latest .",
  ]
}

If .project contains myapp\n, computed.project becomes myapp.

Notes

trimspace removes whitespace from both ends. It does not affect whitespace in the middle of the string.
To remove only trailing newlines, use chomp.
To remove a specific set of characters, use trim.
