#
Tool to print out a parse tree of files in an easy-to-read format. Usage:
nomsu tools/parse.nom file1 file2 directory1 ...
use "lib/os.nom"
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
externally (print tree %t at indent %indent) means:
if %t.type is:
"Action":
say "\(%indent)Action (\(%t.stub)):"
if %t.target:
say "\%indent Target:"
print tree %t.target at indent "\%indent "
for %arg in %t:
if (%arg is syntax tree):
print tree %arg at indent "\%indent "
"Number":
say "\%indent\(%t.1)"
"Var":
say "\(%indent)%\(%t.1)"
else:
say "\%indent\(%t.type):"
for %arg in %t:
when:
(%arg is syntax tree):
print tree %arg at indent "\%indent "
else:
say "\%indent \(quote %arg)"
for %path in (command line args):
for %filename in (files for %path):
if (%filename == "-"): %filename = "stdin"
unless ((%filename == "stdin") or (%filename::matches "%.nom$")):
do next %filename
%text = (read file %filename)
%nomsu = (NomsuCode from (Source %filename 1 (size of %text)) %text)
%tree = (%nomsu parsed)
print tree %tree at indent ""
