Highlighter for SynEdit

[paulee32]

Hello,

for TSynEdit, I would like to implement a custom Highlighter, but I fail.
I have compile the helper tool SynGen, that output, I have modified a little bit:
I would like highlight comments, and block of:
@mainpage    and
@end

The strings in TSynEdit dont be colored. when the @ sign is moved, then they will be colored.
So, How can I use @mainpage ?

here is the grammar.msg file:

Code: Pascal  [Select][+][-]

1. TSynHelpNdocSyn
2. tk
3. IdentStart '@','_', 'a'..'z', 'A'..'Z':: '_', '0'..'9', 'a'..'z', 'A'..'Z'::
4.  
5. TOKENTYPES
6. Identifier
7. Comment      Style=[fsItalic]|Foreground=clGreen
8. Key          Style=[]|Foreground=clBlue

11.  
12. KEYS
13. '@mainpage'
14. '@end'

Hi.

I haven't hear about "SynGen". Maybe it's only for Delphi Synedit.   

Lazarus SynEdit is incompatible with Delphi SynEdit since a long time ago.

I recommend to use SynFacilSyn for Lazarus SynEdit: https://github.com/t-edson/SynFacilSyn . It has a detailed documentation.

Moreover if you want to add completion code, you can use SynFacilCompletion: https://github.com/t-edson/SynFacilCompletion. It's 100% compatible with SynFacilSyn.

Hello,

I search the Internet via Google, and found a hint, to use SynGeneralHighlighter.
This component is indeed under the Palette of SynEdit's Highlighters.

I can put keywords into a StringList, and I have the possibility, to set the FG/BG color of the keywords.
But the Problem is, that the Sign "@" will not be recognize.

So, the keyword "@mainpage"  will not be parsed or colored.
Only "mainpage" as keyword is accepted.

Has someone an Idea, how to use the @ with keyword(s) ?

There is a tutorial: https://wiki.lazarus.freepascal.org/SynEdit_Highlighter

Thank You @all,

I get it done.
The simplest thing was to rename the classname of TSynGeneral to my highlighter,
and do little bit modifications.

You can easily do some similar in SynFacilCompletion.

In the picture you can see a sample XML to set syntax, coloring, folding and completion
