Usage: tool <command> [options] [arguments]
Example:
tool build --portmidi orca
Commands:
build <target>
Compiles the livecoding environment or the CLI tool.
Targets: orca, cli
Output: build/<target>
clean
Removes build/
info
Prints information about the detected build environment.
help
Prints this message and exits.
Options:
-c <name> Use a specific compiler binary. Default: \$CC, or cc
-d Build with debug features. Output changed to:
build/debug/<target>
--harden Enable compiler safeguards like -fstack-protector.
You should probably do this if you plan to give the
compiled binary to other people.
--static Build static binary.
--pie Enable PIE (ASLR).
Note: --pie and --static cannot be mixed.
-s Print statistics about compile time and binary size.
-v Print important commands as they're executed.
-h or --help Print this message and exit.
Optional Features:
--portmidi Enable or disable hardware MIDI output support with
--no-portmidi PortMidi. Note: PortMidi has memory leaks and bugs.
Default: disabled.
--mouse Enable or disable mouse features in the livecoding
--no-mouse environment.
Default: enabled.
