Testing:
fnmatch.translate('./Testfile [comment] some text.*')
'(?s:\\.\\/Testfile\\ [comment]\\ some\\ text\\..*)\\Z'
fnmatch.translate('./Testfile [comment? some text.*')
'(?s:\\.\\/Testfile\\ \\[comment.\\ some\\ text\\..*)\\Z'
It seems it translates [comments] as a set of valid characters to look
for and doesn't care about the [] characters, which is what breaks it, I
assume.
? translates into RegEx .
* translates into RegEx .*
And escaping doesn't work either, because:
https://docs.python.org/3/library/glob.html#glob.escape demonstrates a
way of escaping that works:
glob('./Testfile [[]comment]*')
fnmatch.translate('./Testfile [comment\] some text.*')
'(?s:\\.\\/Testfile\\ [comment\\\\]\\ some\\ text\\..*)\\Z'
...the \ is replaced with \\ which breaks the pattern since it is no
longer a real escape character but an escaped escape character, if that
makes sense.
When the file name has a non working RegEx set, e.g., './Testfile
comment]*' it works.
Yes, easy to say "don't write that into file names," but I don't make the
rules.
I guess I have to write my own.
Oh, well...
