Using grep and regular expression to find class references in a c++ file
I'm trying to math all class references in a C++ file using grep with regular expression. I'm trying to know if a specific include is usuless or not, so I have to know if there is a refence in cpp.
I wrote this RE that searches for a reference from class ABCZ, but unfortunately it isn't working as I espected:
^[^(\/\*)(\/\/)] don't math comments in the begging of the line ( // or /* )
.* followed by any character
[^a-zA-Z] do not accept any caracter before the one I'm searching (like defABCZ)
[]* any white space (I can have something like ABCZ var; )
[\*\(\<:;,{& ] followed by ( * < : ; , & { (I cant get #define "ABCZ.h" or ABCZdef for example)
Well, I can get patterns like this:
Quote:
class Test: public ABCZ{
class Test: public ABCZ {
class Test : public ABCZ<T>
class NameSpace::Test : public ABCZ<T>
ABCZ var = ABCZ();
ABCZ* var = new ABCZ();
ABCZ* var = new ABCZ<T>();
teste = ABCZ(var);
teste = ABCZ(var, otherVar);
teste = ABCZ(var,otherVar);
teste = ABCZ();
funct(*ABCZ av);
struct(ABCZ, BBBB, CCCC);
const ABCZ& getNot_before(void) const;
That's all right, they are all acceptable patterns. But these I'm missing, and they are all acceptable too:
#include "ABCZ.h"
//ABCZ var = ABCZ();
ABCZdef a = ABCZdef();
DefABCZ a = DefABCZ();
ABCZdef a = ABCZdef();
/*ABCZ var = ABCZ();
I don't know if I'm missing any other patterns, if I am, please tell me =p
What am I doing wrong?
I'll be very grateful if someone answer me
Thanks in advance

I suspect this is commonly done, but haven't found the right combination of search terms to find the answer.
I want to grep for lines in .cpp files that contain only 1 '=' sign in an if statement. e.g.,
if (a = b) -- find this
if (a==b) -- don't find this
My attempt:

zgrep
ZGREP(1) General Commands Manual ZGREP(1)NAME
zgrep - search possibly compressed files for a regular expression
SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename...
DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code:
(-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the
standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep.
If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.
EXIT CODE
2 - An option that is not supported was specified.
