Thanks. But the only list I see in the Python lexer is the list of
actual Python keywords. I assume method and function names are read
from the API file.
But what if I want to add additional words to highlight that are not
keywords? The two examples I gave, for instance, are 'self' and
exception names, neither of which are keywords and both of which I'd
like to highlight differently than keywords. So is there a way for me
to define new lists of words, such as one for exceptions?
The C++ code of a lexer says how many keyword lists are defined/used
by that lexer - so adding a new list just by changing the .properties
file is not going to happen *in general*.
Internally, a generic lexer will do tokenizing based on the rules of
that language. When it has identified a token that *could* be a
"keyword" in that language, it will typically check this against the
various "keyword" lists from its .properties file.
This is the sense of the "keywords" we are talking about here - which
may or may not bear a close resemblance to the "keywords" defined by a
language's grammar. This process can also be somewhat different from
what I have described, e.g., because of rules about shortest/longest
matching etc.
Anyway, if the .properties file already has a "keyword" list that
matches what you want in terms of appearance (font, color, weight),
and your desired new entry *could* be in that list based on the
tokenizing rules, then adding to that list will probably work.
But I think this is about the limit of what you can do without hacking
said lexer to define *new* keyword lists. YMMV.
As it happens, the Python lexer seems to define an additional keyword
class it refers to as "Highlighted identifiers"... to use this, just
edit your python.properties and add something like
keywords2.$(file.patterns.py)=self MyException
Note that this will use style# 14 for coloring info when the tokens
self or MyException are encountered in Python source.
Since Neil is "Mr Python" around here, he might have other comments to
add regarding the intended use of this feature of the Python lexer.
