A second pass over those search results throw out bad hits. I recalled that the cache of the header files will not be cleared if they are not touched. But i found that if i do this, for example, // some codes here declare the type of variable foo foo. I had to wait a long time before getting the completions for the first time which could be predicted because there're really many header files. But if i deleted the line above, and re-type "foo.", and get completions again. It will still cost a long time. I'm confused because this file have only several lines, so i don't think re-analyze this file is time consuming. But since other files are not touched at all, they do not need to be re-analyzed, right? > > For most of the analyzer, however, it collects all the datatypes and > names spaces into one big cache.

I think this is a good idea since if i can control when to analyzing, i can also use it when i need recent changes to take effects. Would you mind to provide more details about this or share some configurations of yourself? It will be greatly helpful to me because the main problems i encountered now is that it takes too long before the completions show up. I think most of the time 2-3 seconds is a more reasonable period and i'm willing to use some spaces, for example, the cache can be much larger or something else to optimize the efficiency ( I don't know exactly if this can be done i just use this as an example). CEDET is a great tool, but it will be better if faster. :) > Eric > -- Zhiqiu Kong (孔直秋) |
