where is the option "parse while typiing"?
Menu->settings->Editor->CodeCompletion.
If some piece of memory should be reused, turn them to variables (or const variables).
If some piece of operations should be reused, turn them to functions.
If they happened together, then turn them to classes.

hi,I encouter that the parser can not parse in real-time even I enable "parse while typing".

edit:
     update to the latest svn without any change.

Yes, I can confirm this bug.
If some piece of memory should be reused, turn them to variables (or const variables).
If some piece of operations should be reused, turn them to functions.
If they happened together, then turn them to classes.

the reason is simple.
the variable needParse's scope is function scope.when it (needParse) leave the functioin body.it will be destroyed.so it will be false again when the carect is in different line.

Oh, look this screenshot.
Code
#include <iostream>
#include <string>

using namespace std;

int main()
{
    basic_string<wchar_t> ws;
    ws.
    return 0;
}
@Loaden
This works fine here, rev 6083.
You can see the screen shot below:

If you drag the scroll bar prompt window, you will find many non-basic_string <T> function, it seems from iostream.

you can not use variable name ws here.because it has been defined in istream.tcc which belong to gcc files.


Note:

try another name e.g. wsss,you will get the answer.

Good! So, this is not a problem. :wink:

Just a reminder:

@morten

This is a big bug, should be fixed soon.

Re: The 12 January 2010 build (6080) is out.

Below code works fine.
Code
#include <iostream>
#include <string>

int main()
{
    std::wstring ws;
    ws.
    return 0;
}

I don't get it. m_NeedReparse was used just there. So what's wrong with this piece of code:
Code
    Parser* parser = m_NativeParser.GetParserPtr();
    bool needReparse = false;
    if (   parser && parser->Options().whileTyping
        && (   (event.GetModificationType() & wxSCI_MOD_INSERTTEXT)
            || (event.GetModificationType() & wxSCI_MOD_DELETETEXT) ) )
    {
        needReparse = true;
    }
    if (control->GetCurrentLine() != m_CurrentLine)
    {
        if (parser && needReparse)
            parser->Reparse(editor->GetFilename());
        else
            FindFunctionAndUpdate(control->GetCurrentLine());
    }
It will trigger the re-parse correctly in the case a parser is present, the option is enabled and a char was inserted/deleted.

So...?! (I am a bit sick, so probably you should explain slowly... ;-)).

Done in my local copy. Will commit in a while... probably after blueshake answered the other question which may require some modifications, too.

see the codes below,in the new codes,it declare a new variable needReparse ,not m_NeedReparse.
    Parser* parser = m_NativeParser.GetParserPtr();
    bool needReparse = false;
    if (   parser && parser->Options().whileTyping
        && (   (event.GetModificationType() & wxSCI_MOD_INSERTTEXT)

To make it clear, why the current code does not work:

needReparse is set to true whenever text is inserted or deleted, but the reparsing is only triggered if we leave the current line.
This does normally (never ?) happen inside the same event, so we have to remember whether a reparse is needed, either with a member-variable or a static local variable.
