This is an example how to write a highlighter from scratch.
|
|
|
|
See the units for each example highlighter.
|
|
|
|
This is NOT about extending the IDE. This is about SynEdit and it's Highlighter only.
|
|
Therefore this does not include:
|
|
- registration in the component pallette.
|
|
- Using the Object Inspector
|
|
Those steps are the same as they would be for any other self writen componont.
