Syntax coloring is done in two steps:
1. colorize based on simple tokens, like keywords, string literals, etc.
2. colorize based on the semantic of names (functions, typedefs, etc.)
The second step requires building an AST (abstract syntax tree) from the
source and resolving the names to their "bindings", ie. their semantic
meaning. In the presence of syntax (or other) errors, this name
resolution may fail and therefore no coloring will be applied.

Thank for your reply.
Well then, syntax coloring based on the semantic would be easy to get
some problems in various situations.
In fact, even if simple project and syntax is rights, the coloring was
not applied.
for example, I included glib.h into my C make project to use ADT such
GSList, GHashTable. but no coloring was applied for typedefs such
GSList, GHashTable.
this is certain bugs.
in another side, the semantic coloring can't work in real time while
writting codes on just a line. then where is I can get the convenience
from syntax coloring? just in the time read sources?
change back to the first purpose of syntax coloring and even code assist
what should do in coding time is certain.
thank you.

Hi,
I do not know if Misoullee's problem has been solved, but I have run into a similar issue as well.
I use eclipse IDE primarily for editing only, not even building or debugging. In our project, not all symbol errors wil be resolved, simply because, not all the source is owned/visible to us.
However the syntx coloring not working for unresolved symbols is reducing my concentration and efficiency. For e.g. I have set function calls to be highlighted in bold. The functions which are not resolved are not highlighted, and when I hover my mouse pointer over the function, it says "Function XYZ could not be resolved"
My question is -- as long as the eclipse IDE figures out that it is a function, why not apply the coloring, no matter whether it is resolved or not?
