Perl language syntax highlighting troubles (bug or limitation ?)
-
check line 111 - it defines the lexer_name
-
OOPS, yours :== self.lexer_name, mine :== self_lexer_name, I am really a dumb when dealing with OO programming, can’t realize that ‘self’ is the current object and of course separated by a dot.
Colour has changed for q* keywords and there text (black on dark blue, can’t read but now just need to ajust the colors).
No change for here docs, but don’t know if I properly set the colors, have to check.Send you a screen copy in a few minutes.

All right, nearly done: with the following regexp in your python code:
regexes[(1, (255,0,128))] = (r'\bq[rwqx]{0,1}\b([^\h]).*?\1|(\bq[rwqx]{0,1}\b\h+(\w).*?\3)', [0]) regexes[(2, (255,0,128))] = (r'\bq[rwqx]{0,1}\b\h*(\(.+?\)|\[.+?\]|\{.+?\})', [0]) regexes[(3, (0,0,0))] = (r'(?s)((<<)"*(\w+?)"*;.*?\3)', [2]) regexes[(4, (0,0,0))] = (r'(?s)((<<)\h+"(\w+?)";.*?\3)', [2,3])I get the following colors:
Q* colors are good {well I might have an uggly taste in colors but at least they match ;-)) }
Would you have any clue about why the here docs= are still not handled properly ? They should be black, I think.
-
the regexes assumes double quotes and semicolon directly attached to EOT.
Likeprint << "EOT"; --------------------- separation line ------------------ EOTIs there a rule how this is specified?
-
I think I found why.
Your regexp says :
r'(?s)((<<)"*(\w+?)"*;.*?\3)'
would not it be better if :
r'(?s)(\h*(<<)\h*"*(\w+?)"*\h*;.*?\3)'???
To answer your question:
Perl allows
- <<TEXT,
- << TEXT
- <<‘TEXT’ / << ‘TEXT’
- <<“TEXT” / << “TEXT”
meanings differ in each case…
-
To be honest - I’m not a regex expert at all :-D
If you, as a perl developer, say so I would absolutely believe it is :-) -
In your Python regexp, what’s the meaning of:
- “\3”
- “, [2]” and “[2,3]” ?
If I can understand what I think I could translate a Perl regex code into python (for this case at least).
-
What about using this
(?s)((<<)\h+(["|'])(\w+?)\3\h*;.*?\4) -
- is the boost:regex convention to denote match group 3
and - defines which match group actually should be painted
Like if you have:
r'(word1)(word2)(word3)', [2,3]would mean that only word2 and word3 would be painted
whereas if you would specifyr'(word1)(word2)(word3)', [0]everything would be colored.
Does this makes sense to you?

I don’t understand your regexp syntax. Perhaps too ‘pythonized’ for me.
(?s) : what does it mean ? is it ‘s///’ ? or really a non capturing group of ‘s’ ???
\3 \4 : are they $3 $4, I don’t think as I can’t see a 4th accumulator -
(?s) is a modifier telling the engine that the dot matches line endings
and yes, the engine uses \1 and $1Here the link to the documentation - maybe easier for you.
-
ooppps
(?s)((<<)\h+(["|'])(\w+?)\3\h*;.*?\3):-D
-
This post is deleted! -
Ok
another one: in Python you must say["|']instead of Perl["'](‘either one of the set’) ? Is that what it means ? -
No, afaik non-capturing group is (?:pattern)
This, (?s), just tells the engine that the dot.is matching
EOLs like\r\n- if I’m right. -
Just for clarification, the python script does NOT use the python regex engine instead
it uses the one notepad++ offers, the boost::regex.
Yes, you can use the enumeration without the pipe but makes it more visible for me with
the pipe sign. Or is there a difference if used with pipe sign or without? -
or maybe this one might be even better
(?s)(<<)\h+(["'])(\w+?)\2\h*;.*?\3 -

I have no idea why this happens sometimes.
By the way, now that you have installed pythonscript plugin would you mind
clicking Plugins->Python Script->Scripts->Samples->RegexTester ?I know not everyone is recommending it but, personally, I love it.
-
AFAIK, at least in Perl, ["|'] means double-quote OR pipre OR simple-quote, everything between square brakets is literal. Also true in “awk” and C regexp I think.
I don’t know for Python.
