is a fork of the [shell] external from Günter Geiger's ggee library.
It provides a way to execute commands from Pd. Its goal is to give more fine-grained control over the process it manages. Unlike the original [shell] external, [command] executes commands directly and does not wrap them into a shell. This means shell features cannot be used with [command]. However, they can be used in shell scripts that can be executed with [command].
- runs asynchronously (without blocking Pd)
killmethod for sending SIGINT to currently running command.sendmethod for sending data to STDIN of currently running command.envmethod for setting environment variables.- separate outlet for STDERR of command.
- reports exit code on left-most outlet.
- uses dedicated method
execfor command execution to avoid conflicts between command and method names. - searches relative to patch instead of relative to Pd when calling commands with relative path. This makes projects using custom scripts or binaries more portable.
-bflag for binary output. This can be used to bypass FUDI parsing. Useful for cases when characters like leading or trailing spaces should be kept.-sflag for synchronous mode. When enabled, command execution blocks Pd while maintaining depth-first order.
