Hi,<br>
<br>
I'm developing an IDE which uses clang API (clang-c/Index.h).
Eventually I intend to implement<br>
Syntax highlighting, indentation, diagnostics and code completion.
So clang is just perfect.<br>
<br>
My 2 questions are :<br>
<br>
Its seems that in the API, the only option is
clang_parseTranslationUnit/clang_<b>re</b>parseTranslationUnit.<br>
The thing is, that those functions receive as a parameter either a
file name on a disk or a file name<br>
in memory in a form of const char* pointer and length. The open file
in my IDE is not stored in that<br>
straightforward way in the memory (or I guess any other text editor)
so is there a way to feed the parser from a byte stream of any sort?<br></div></blockquote><div><br></div>No, there isn't. You'll need to copy your data into a const char* buffer to use libclang.</div><div><br><blockquote type="cite"><div bgcolor="#FFFFFF" text="#000000">
The second question is: Currently I try to implement syntax
highlighting, which means that <br>
for every press of a key (pretty much) in the editor I need to re
parse and tokenize the entire file, so that I'll get the updated
information on how and what to highlight. While clang performs those
action <br>
quite fast, and for diagnostics and code completion this totally
acceptable, I do feel that its a bit of an overkill for syntax
lighting where simple (and maybe partial or incremental) tokinizing
of an input<br>
buffer would be sufficient.<br>
Is there something I'm missing? Are t there are other clang methods
that I can use ?<br></div></blockquote></div><div><br></div>There aren't any other libclang methods to use. Generally, we suggest that you implement a bit more logic on the client side to avoid calling clang_reparseTranslationUnit that often. For example, wait until the user has typed enter/return or some closing character like }, ), or ].<div><br><div><span class="Apple-tab-span" style="white-space:pre"> </span>- Doug</div></div></body></html>
