When using Boost::spirit, I have an issue with assist++ scanner : it get's stuck in Boost headers.
So if I want to be able to use Assis++, I have to comment Boost header #include, launch rescan of all files, uncomment the boost headers #include

As BLITZ can be disabled on certain files using
#pragma BLITZ_PROHIBIT


Maybe Assist++ scanning could be disable using something like
#pragma ASSIST_SCAN_PROHIBIT

Hello,

I found missing documentation page that speaks about your problem. The assist parsing can be turn off by following macros (part of missing documentation):
5. Assist++ C++ parser directives
Assist supports simple directives that are passed to it via '//' comments that can be used in cases that original code is confusing:
//$-
Code past this directive will not be passed to parser.
//$+
Code past this directive will be passed to parser (stops //$-).
//$ code
example: //$ void Foo(Bar&)
Code will be passed to parser (adds code that is not part of compiled sources)


The documentation page will be available tomorrow and it will be bundled with TheIDE. I hope my message will help you to deal with your problem.

Sincerely,
Klugier

Hi Klugier,

I was filled with hope when I saw you're answer thinking i've ignored this for so long... but it doesn't work Crying or Very Sad Crying or Very Sad Crying or Very Sad Crying or Very Sad Crying or Very Sad Crying or Very Sad
I even tried the other way around Confused

Hello,

I took some time to find out why it doesn't work in my case, and I think I found a candidate
//$+ and //$- work when parsing the code of a file
But .... the list of files is extracted from the package files and file #include without taking into account the //$+ and //$-
The function that does this extract seems to be (Is this correct ??) : ide/Browser/Base.cpp
BaseInfoSync(Progress& pi)


So the following code does not behave as I expected : I thought the includes (and the included files) would not be processed by assist++
//$-
#include <boost/config/warning_disable.hpp>
#include <boost/spirit/include/qi.hpp>
#include <boost/spirit/include/phoenix_core.hpp>
#include <boost/spirit/include/phoenix_operator.hpp>
#include <boost/spirit/include/phoenix_fusion.hpp>
#include <boost/spirit/include/phoenix_stl.hpp>
#include <boost/spirit/include/phoenix_object.hpp>
#include <boost/spirit/include/phoenix_bind.hpp>
#include <boost/fusion/include/adapt_struct.hpp>
#include <boost/variant/recursive_variant.hpp>
#include <boost/foreach.hpp>
//$+


Maybe the file should be preprocessed by :
CppBase/Pre.cpp
SrcFile PreProcess(Stream& in, Parser& parser)

Before extracting the list of files to be processed by Assist++

Well I finally found some time to look into this problem and actually found something that works.

Code is just a first quick try, but before going further I would like to share it first and have some return on it.

* in uppsrc/CppBase/CppBase.h

const char *SkipString(const char *s);

void RemoveComments(String& l, bool& incomment);
void RemoveDirectives(String& l, bool& inDirective);    // ======= ADDED THIS LINE  ============

String GetStdDefs();


* in uppsrc/CppBase/ppFile.cpp
Added the following function:
void RemoveDirectives(String& l, bool& inDirective)
{
	int q = -1;
	int w = -1;
	if(inDirective)
		q = w = 0;
	else {
		const char *s = l;
		while(*s) {
			if(*s == '\"')
				s = SkipString(s);
			else
			if(s[0] == '/' && s[1] == '/' && s[2] == '$' && s[3] == '-') {
				q = int(s - ~l);
				break;
			}
			else
				s++;
		}
		if(q >= 0)
			w = q + 4;
	}
	while(q >= 0) {
		int eq = l.Find("//$+", w);
		if(eq < 0) {
			inDirective = true;
			SetSpaces(l, q, l.GetCount() - q);
			return;
		}
		SetSpaces(l, q, eq + 4 - q);
		inDirective = false;
		q = l.Find("//$+");
		w = q + 4;
	}
}


* Modified ppFile::parse() method
void PPFile::Parse(Stream& in)
{
	LTIMING("PPFile::Parse");
	for(int i = 0; i < ppmacro.GetCount(); i++)
		sAllMacros.Unlink(ppmacro[i]);
	ppmacro.Clear();
	item.Clear();
	includes.Clear();
	bool was_using = false;
	bool was_namespace = false;
	int  level = 0;
	bool incomment = false;
	bool inDirective = false;     ========== line added ===========
	Vector<int> namespace_block;
	bool next_segment = true;
	Index<int> local_segments;
	keywords.Clear();
	int linei = 0;
	Md5Stream md5;
	while(!in.IsEof()) {
		String l = in.GetLine();
		while(*l.Last() == '\\' && !in.IsEof()) {
			l.Trim(l.GetLength() - 1);
			l.Cat(in.GetLine());
		}
		RemoveDirectives(l, inDirective);       ========== line added =========
		RemoveComments(l, incomment);
		try {
			CParser p(l);

I have now fixed the original issue (parser does not get stuck there anymore) and also implement a little bit more polished version of directives to remove #includes.

Well I checked latest SVN version :

* Without //$- //$+ : scanner still gets stuck in boost headers
* With //$- //$+ : everything is OK

So for me it's all good since I don't need to scan the boost headers.

Thank's for makng the changes to ide

We really need that to work... Where does it get stuck? (Perhaps send screenshot of progress....)

What is the version of boost?

It always get's stuck on the same file

Please check and report the svn version of theide as an infinite loop is exactly what I have fixed...

I just checked with latest svn version (13596) and it works now !!! Smile

Many Many Thank's, this was very annoying


My previous test, which did not work, was made with svn 13591

The boost version used is : 1.63.0

I am on linux (fedora) and compile with CLANG

Linux version 4.13.16-100.fc25.x86_64 (mockbuild@bkernel01.phx2.fedoraproject.org) (gcc version 6.4.1 20170727 (Red Hat 6.4.1-1) (GCC)) #1 SMP Mon
