one-line bug in templatablepattern.py

[jkmnt]

Description

• [ -] Source branch in your fork has meaningful name (not main)

Fixes Issue:

The templatablepattern.py contained the bug:

    def read(self):
        if self._until_after:
            result += self._input.readUntilAfter(self._until_after) # should be self._until_pattern

the self._until_after is bool flag, while the readUntilAfter accepts the regexp.
The same code in templatablepattern.js uses the this._until_pattern correctly.

The fact that this doesn't cause test failures means this code must not be exercised in Python.

Ah, I see. You discovered this as part of porting the HTML beautifier.
