QAST tree visualizer
q command line script that parses out QAST trees from a program and makes an HTML file from them.
The HTML page provides these extra features unavailable in plain
raku --target=ast and
raku --target=optimize output:
Control-click on individual tree nodes to collapse/expand them
Color coding: of sunk nodes,
QAST::Want alternatives, static and non-static
Usage: q a '[<args> ...]' q o '[<args> ...]'
$ q a raku -e 'say "hello"' > out.html; google-chrome out.html
a stands for
--target=ast and the args that follow is a
raku invocation to run the script (the
--target=ast argument will be inserted automatically).
The script will parse QAST generated by the given
raku program and output an HTML file to STDOUT. View the file in any browser to examine the QAST tree.
$ q o raku -e 'say "hello"' > out.html; google-chrome out.html
o stands for
--target=optimize . Same as
a , except parses
--target=optimize QAST. Once again, you don't need to manually specify
$ q z raku -e 'say "hello"'
Just runs the raku command as is. Mnemonic: "zero". This command exists simply to easily switch between
a`/`o runs and plain raku runs.
