New syntax highlighting lexer (Motorola 68000 asm)
Folco:
Hi,
I have used this page to write a lexer for my favorite language : http://wiki.codeblocks.org/index.php?title=Creating_a_custom_lexer_for_Code::Blocks_editor
The explanations help a lot, but there is still one thing that I don't understand. The full lexer is here : http://www.mirari.fr/6VIJ
What I don't understand it the index that I must put in the <Keywords> field :
<Set index="0" .../>, <Set index="1" .../> and <Set index="2" .../>
==> I don't understand to what "0", "1" and "2" refers to ?
As says the Wiki doc, I have downloaded Scite sources, looked at .properties files, but it didn't help me :(
In my case, the instructions are not in the right color and style (I wanted them bold).
Could someone give me some tip to me be able to complete this lexer ?
Thanx in advance. :)

Nobody can help me ?
I didn't find an already existing lexer. I didn't find a scintilla forum, I didn't find anything in the scintilla or scite doc, in the linux packages or in their sites...
If someone could show me some documentation, it would be very helpful !
Folco:
I have succeed in doing a lexer which works quite fine ! http://www.mirari.fr/Nyp2
But there is still something I can't do : in asm 68k, hexa number are written $12AB, binaries %1010, integer are prefixed with '#' : #$ABCD.
I don't know how to say to the lexer that '$', '%' and '#' must be considered as numbers.
An idea ?
BTW, I have configured C::B to have tabs of eight chars, my .sample file contains tabs, but the preview uses 4-chars tabulations, not what the user have defined (it's a bug ??).
Is there a mean to change indentation size when using a specific syntax highlighting ?
I would also want to make some regular expressions to be considered as symbols or other things : [a-zA-Z]+[ @ ][a-zA-Z]. A mean to do that ?

Here a permanent link where you can download "Asm Motorola 68k" syntax highlighting : http://www.mirari.fr/fgP1

For those who would be interested in writing their own lexer, you can find some documentation in the sources of Scintilla shipped with Code::Blocks.
The SetIndex values are defined in a table at the end of the .cpp files which handle coloration. These files are in src/sdk/wxscintilla/src/scintilla/lexers/Lex*.cxx.
For the asm files, this table is used :
--- Code: ---static const char * const asmWordListDesc[] = {
"CPU instructions",
"FPU instructions",
"Registers",
"Directives",
"Directive operands",
"Extended instructions",
0
};
--- End code ---
The Index number (the "magic" number I was asking about in post #0) must follow this table :
0 for CPU Instructions
1 for FPU
2 for Registers
etc...
Quite simple, when you know where the informations are. :D
