Hi, I’m trying to create a syntax-based Fold command, so far the command works well when all markers are balanced, it works by level too:
but fails when at least one marker is not matched:
def get_folds(self, level: int, regex: str, ignore: str) -> [sublime.Region]:
text = self.view.substr(sublime.Region(0, self.view.size()))
# regex contains two named groups, start and end
markers = ((m.groupdict(), sublime.Region(*m.span()))
for m in finditer(regex, text)
if not self.view.match_selector(m.start(), ignore))
i = 0
regions = []
matched = True
for g, r in markers:
# found a start marker
if g['start']:
i += 1
# found an end marker
elif g['end']:
i -= 1
# found a start marker at level
# take the position after the marker
if i == level and matched:
x = r
matched = False
# found an end marker at level
# take the position before the marker
elif i == level - 1 and not matched:
regions.append(sublime.Region(x.b, r.a))
matched = True
return regions
how can i change the algorithm to not fail when markers are not balanced ?
