44 |
common superclass for (smalltalk-) syntax highlighting. |
3599 | 45 |
|
46 |
This will parse the source code and update the local copy of the |
|
47 |
sourceText (in that instvar) by changing emphasis and color, |
|
48 |
as syntax elements are encountered. |
|
49 |
This is done by redefining appropriate markXXX methods, which are |
|
50 |
called by the parser whenever an interesting syntactic construct is encountered. |
|
51 |
These methods are no-ops in the Parser class, but redefined here to update |
|
52 |
the colorization of sourceText. |
|
4200 | 53 |
|
54 |
Caveat: |
|
55 |
used to be a smalltalk syntax highlighter and therefore (wrongly) subclassed Parser. |
|
56 |
However, over time, much functionality was added, which is of use for other languages also |
|
57 |
and this class will therefore be changed to use composition and have parsing delegated. |
|
58 |
to be independent of the language and to not inherit stuff, which is not needed. |
