I'v write something to do this thing, you can change it to a custom filter:
import re
import cgi
re_string = re.compile(r'(?P<htmlchars>[<&>])|(?P<space>^[
\t]+)|(?P<lineend>\r\n|\r|\n)|(?P<protocal>\b((http|ftp)://.*?))(\s|$)',
re.S|re.M|re.I)
def plaintext2html(text, tabstop=4):
def do_sub(m):
c = m.groupdict()
if c['htmlchars']:
return cgi.escape(c['htmlchars'])
if c['lineend']:
return '<br>'
elif c['space']:
t = m.group().replace('\t', ' '*tabstop)
t = t.replace(' ', ' ')
return t
elif c['space'] == '\t':
return ' '*tabstop;
else:
last = m.groups()[-1]
if last in ['\n', '\r', '\r\n']:
last = '<br>'
return '<a href="%s">%s</a>%s' % (c['protocal'],
c['protocal'], last)
return re.sub(re_string, do_sub, text)
