Assist - rescan code vs caching in files.... [message #18093]

Seeking for advice Smile

Assist++ has quite complex mechanism that stores parsed information into files (in 'cfg' directory) when theide exists and reloads it from there on theide start.

Recently I have started to worry if this is a good idea.

Well, the primary reason to worry is that the mechanism for storing and retrieving is quite complex and fragile.

Maybe it would be OK to rescan the code each time theide starts?

So the question is:

- if you load "ide" package, how long it takes initial start sequence (most of it is spent loading assist++ from file cache).

- can you compare this to invoking "Assist/Rescan code"?

First time opening "ide" package:
14s (src files uncached, and probably not scanned)
Rescan:
4s (since here src files are probably cached by OS in RAM)
Exit+Reopen IDE:
1s
Rescan:
4s

BTW, what about full rescan after start of IDE in the background?
In case that one will take around 10-30s even with more intelligent parser, I think that's perfectly acceptable solution, I usually stare into the source files for more than a minute or two before I catch up where I left and start to write something.

edit: the important thing is to let me "stare" at them, that's the reason why it should run in background. The current modal foreground rescan or load after opening package annoys me. It's just 1-5s, but can be zero in ideal world of background scanning Smile

Well, I am afraid that making more inteligent caching system is much easier than scanning in background Wink

Moreover, I believe that in process of "staring", you would soon start requiring class browser....

Well, I think I will fix the caching Smile

I don't know if it is worth to put an effort in the caching. After all you don't open a project every 5 minutes. And with the caching there could be problems with updates of the code from outside TheIDE, couldn't there?

Not really. Compared to other assist++ problems, this one is trivial Smile
