Hi,
Here is how you can parse Pd patches into rows of atoms in three languages using regular expressions:
/*** Javascript ***/
var lines_re = new RegExp("(#((.|\r|\n)*?)[^\\\\])\r{0,1}\n{0,1};\r{0,1}\n", "gi");
for (pdline = lines_re.exec(patchtext)) {
var atoms = pdline[1].split(/ |\r\n?|\n/);
}
### Python ###
lines_re = re.compile("(#(.*?)[^\\\])\r{0,1}\n{0,1};\r{0,1}\n", re.MULTILINE | re.DOTALL)
split_re = re.compile(" |\r\n?|\n", re.MULTILINE)
for found in lines_re.finditer(patch):
line = found.group(1)
atoms = split_re.split(line)
/*** Java ***/
private static final String line_re = "(#((.|\r|\n)*?)[^\\\\])\r{0,1}\n{0,1};\r{0,1}\n";
private static final String token_re = " |\r\n?|\n";
Pattern pattern = Pattern.compile(line_re, Pattern.MULTILINE); Pattern token_pattern = Pattern.compile(token_re, Pattern.MULTILINE); Matcher matcher = pattern.matcher(patchtext); ArrayList<String[]> atomlines = new ArrayList<String[]>(); while (matcher.find()) { String[] s = token_pattern.split(matcher.group(1)); atomlines.add(token_pattern.split(matcher.group(1))); }
Also here is a regular expression for matching dollar args:
/(?:\\{0,1}\$)(\d+)/g;
Hopefully this is useful to someone else.
Cheers,
Chris.

It will be :)

Sounds very useful, and would be great to have on the wiki, anywhere
in the docs/developer section, for example.

Hi Hans,
Excellent, I will put it in there. Sorry to be dense, but could you provide me with a link to the page in this wiki you speak of? Or is that the Plone thing?
Cheers,

Sorry, I mean most of puredata info is a wiki, including the /docs/
section. You could just add a wiki page to the root, for example:

Looking at things from a more basic level, you can come up with a more
direct solution... It may sound small in theory, but it in practice,
it can change entire economies. - Amy Smith

Works for me, I just quickly converted it to MoinMoin syntax like the
rest of the docs in that section.
