I assume I'll have to make my own as well? I'm currently using the one for Python, which works, but... meh. I searched around here and google but didn't really get anywhere, can someone point me to some info about writing a custom lexer? Thanks! Custom syntax highlight using RegExp (AlexAndrei) http://pnotepad.org/forums/topic/5095#post-7440 Thu, 28 Oct 2010 23:26:02 +0000 AlexAndrei 7440@http://pnotepad.org/forums/ Hello, I would need some help with a way to have a custom syntax highlight, using regular expression. I work a lot with software generated traces, that have various messages with common prefixes and suffixes. Something like: (A|B)_(.+)_(request|confirm) A_message1_request B_message2_confirm etc Is there a way to define for example two classes of keywords, one for _request messages, one for _confirm messages, with different styles, and using regular expressions ? I could enter all messages by hand, but there are quite many, and also they change in time. Thank you in advance! PS: Using PN 2.1.5 + PyPN 1.12. A PyPN method would also be acceptable, but I would prefer to avoid it for now. Regards, Alex Must lexer tokens be surrounded by whitespace?

I'd like to write a PN lexer for BBC BASIC, but it has unusual requirements: keywords do not (necessarily) need to be surrounded by whitespace. For example the following is legal syntax in BBC BASIC (although not encouraged!): x = DEGACSCOSPI where 'DEG', 'ACS', 'COS' and 'PI' are all separate keywords! Can a custom PN lexer handle this situation, and if so where can I find out how to write it?

Was about to write a lexer for scintilla, and use notepad++, but then found PN and prefer the interface!! So, before I embark on creating a lexer - is it actually possible in the existing lexers to define keywords with spaces in? Many thanks....

I'm creating schemedef for the Euphoria programming language. What is the lexer and how can I make my own? 2. I used vhdl lexer but for some reason the following tags don't have any effect. Why? <stringtype id="1" start="'" end="'" multiline="false" escape="\" /> <comments><line start="--" /></comments> 3. I would like to have different syntax coloring for euphoria_keywords and euphoria_datatypes. Is it possible? 4. The following setting makes single minus char act like a number: <numbers start="[-#0-9]" content="[#0-9a-f.x]" /> Why? It should be syntax colored to number only if following chars contains numbers or #. Here's what I've achieved so far: euphoria.schemedef <?xml version="1.0" ?> <Scheme> <keyword-classes> <keyword-class name="euphoria_keywords"> and end include to by exit not type constant for or while do function procedure with else global return without elsif if then xor as </keyword-class> <keyword-class name="euphoria_datatypes"> atom integer sequence object </keyword-class> </keyword-classes> <schemedef name="euphoria" title="Euphoria" author="Tapani Talvitie" url="http://www.pnotepad.org/" version="1" casesensitive="true" braces="{[()]}">  <lexer name="vhdl" /> <strings>  <stringtype id="0" start=""" end=""" multiline="false" escape="\" /> <stringtype id="1" start="'" end="'" multiline="false" escape="\" /> </strings> <identifiers start="[a-zA-Z]" /> <comments> <line start="--" /> </comments> <numbers start="[-#0-9]" content="[#0-9a-f.x]" /> <use-styles> <style name="Default" key="32" fore="000000" bold="false" /> <style name="Line Comment" key="1" class="comment" fore="007f00" bold="false" /> <style name="Keywords" key="5" class="keyword" fore="00008b" bold="true" /> <style name="String" key="10" class="string" fore="800080" bold="false" /> <style name="String 2" key="11" class="string" fore="800080" bold="false" /> <style name="Number" key="4" class="number" fore="800080" bold="false" /> <style name="Identifier" key="3" fore="000000" bold="false" /> </use-styles> <use-keywords> <keyword key="0" name="Keywords" class="euphoria_keywords" /> <keyword key="1" name="Keywords" class="euphoria_datatypes" /> </use-keywords> </schemedef> </Scheme> Best Regards, -- Tapani Talvitie D scheme / making portable (bcat) http://pnotepad.org/forums/topic/139#post-510 Sat, 11 Nov 2006 02:54:07 +0000 bcat 510@http://pnotepad.org/forums/ Hi simon. I just wanted to let you know that there are a couple problems with the D scheme in 2.0.7.610. 1) The .d extension isn't associated with the D scheme, so D files come up as plain text by default. 2) The keyword list is incorrect. Here's an updated version from the language spec: abstract alias align asm assert auto body bool break byte case cast catch cdouble cent cfloat char class const continue creal dchar debug default delegate delete deprecated do double else enum export extern false final finally float for foreach foreach_reverse function goto idouble if ifloat import in inout int interface invariant ireal is lazy long mixin module new null out override package pragma private protected public real return scope short static struct super switch synchronized template this throw true try typedef typeid typeof ubyte ucent uint ulong union unittest ushort version void volatile wchar while with 3) The line/stream/box comment menu items don't work. Line comments should start with <code>//</code>. Stream comments should be within <code>/* ... */</code>. What are box comments? 4) <code>/+ ... +/</code> style nested comments are not supported at all. Question about auto-(complete|closing) (jp) http://pnotepad.org/forums/topic/46#post-180 Thu, 13 Apr 2006 06:16:07 +0000 jp 180@http://pnotepad.org/forums/ Hello, I've just found this piece of quality software and it's just what I've been looking for, except for one little feature. This might have been already implemented (at least the lexer has the required functionality afaik), but I was unable to find any solution for this with a quick look-around; is there a way to enable a auto-(complete|closing) of tags, brackets and such? As in, if I'd type in a , after I've input the closing bracket (>), the pn would automatically insert the closing tag after the cursor? You know what I'm talking about don't you? Sorry if my explanation is a bit odd but I didn't figure out any better way to express myself after a 14h workday. :) The feature I'm talking is like those text clips you have in editor expect that the functionality is automated. I'm not talking about code-completion a l� VS or any other bloat IDEs like with method-dropdowns or such.
