Runscript

Runscript is a tool like make which manages run commands. Runscript can also handle building, but it doesn't track file update times (yet?), so you may still want to use make for that (but you can call it from runscript).

For an example of a useful runscript, see the runfile for this repository.

How to install

Binaries are available from the releases page. Alternatively, you can use cargo to build and install it. Supporting package managers is difficult, so I'm not going to try doing it until this gets real use.

Cargo

If you have cargo, and are fine with building from source, runscript is on crates.io

cargo install runscript

How it works

When run is executed, it looks for a file run in the current working directory (other files can be specified). It searches this runfile for scripts, which look like the following:

#target phase
commands
#/

target can be - for the default target, # for the global target, or anything else for a named target (matching the regex [A-Za-z0-9_]*).

phase can be one of the following sets of characters:

The phases that are executed depend on flags passed to run.

If multiple phase flags are passed, the one provided last is used.

commands is a newline-separated list of terminal commands to be executed. In other words, a shell script. Not all script features are currently supported, however. A list of supported features follows:

• Commands and arguments
• Argument interpolation:
  • *.run glob matching (only *, ?, **, {})
  • $VAR environment variables
  • $(echo) internal subcommands
  • $1 positional arguments
  • $@ all positional arguments
• Single and double-quoted arguments
• Command chaining by &&, ||, and | (no ;, just use newlines)
• VAR=val Environment variable setting (with interpolation)
