Hi all,
I work a lot with java code, that uses some DSL inside strings, like
myJavaMethod("from x : V with x.count < 17 reportSet x end");
Is there a way to extend the usual syntax coloring for java with some
basic highlighting inside java string literals?
For now, I would be fully satisfied with making a fixed set of DSL
keywords bold inside strings. In the example above, those are "from",
"with", "reportSet" and "end".
I had a brief look at the JDT docs, and if I understand correctly, the
coloring is done by some lexer (aka RuleBasedScanner) returning a token
list, and the color for each token is determined by some IColorManager.
And of course, for a java lexer a string literal is one single token, so
any highlighting inside string literals is impossible.
Please tell me that I am either totally wrong, or that I'm right but the
thing I want to do is still easily possible. ;-)
I appreciate any pointers!
Tassilo
