Line Count in my Qt Project.
-
I had some time during breakfast :-)
#include <QCoreApplication> #include <QDir> #include <QFile> #include <QTextStream> #include <QVector> int countLines(QString path){ QFile f(path); int cnt = 0; if(f.open(QIODevice::ReadOnly | QIODevice::Text)){ QTextStream read(&f); while(!read.atEnd()){ read.readLine(); cnt++; } } f.close(); return cnt; } int parseDir(QString path){ int cnt = 0; QDir dir(path); QStringList dirs = dir.entryList(QDir::AllDirs |QDir::NoDotAndDotDot); QStringList file = dir.entryList(QDir::Files); for(QString dir : dirs){ cnt += parseDir(path + "/"+dir); } for(QString s : file){ if(s.splitRef('.').last() == "h" || s.splitRef('.').last() == "cpp") cnt += countLines(path + "/"+s); } return cnt; } int main(int argc, char *argv[]) { QCoreApplication a(argc, argv); int count = 0; count += PathDir(a.arguments().last()); QTextStream out(stdout); out << "Lines in project: " << a.arguments().last() << ": "<< endl <<count << endl; return a.exec(); }@J.Hilk Well, it is a bit more complex :-) For example your version counts empty lines and comment lines.

@jsulm well obviously :-P
but that could be addressed e.g:int countLines(QString path){ QFile f(path); int cnt = 0; if(f.open(QIODevice::ReadOnly | QIODevice::Text)){ QTextStream read(&f); QString line; bool comment = false; while(!read.atEnd()){ line = read.readLine(); line = line.simplified(); line.replace(" ",""); if(line.size() >0){ if(line.leftRef(2) != "//"){ if(line.contains("/*")) comment = true; if(line.contains("*/")) comment = false; if(!comment) cnt++; } } } } f.close(); return cnt; } -
Thanks All for the help.
Moving to solved. -

find and grep...find and grep
@Kent-Dorfman would you like to elaborate a bit more?
-
find . -iname \*.h -o -iname \*.cpp -exec grep \\\; {} \; | wc -lWould find all the .h and .cpp find in the current directory, and count the number of lines with a semicolon. For the most things, that's probably a pretty useful count of code LOC, and requires no extra tools to be installed.

This don't do the folder search recursive right. ?Pradeep Nimbalkar.
Upvote the answer(s) that helped you to solve the issue...
Keep code clean. -

yes, the default behaviour of find "in unix" is recursive. grep is a pattern matcher. I use
find . -type f -iname \*.h -o -iname \*.hpp -o \ -iname \*.c -o -iname \*.cc -o -iname \*.cxx \ -o -iname \*.cpp | \ xargs -n 1 egrep -v "^[ \t]*$" | wc -lprints total of all target file lines (found recursively). ignores blank lines

Hi @Kent-Dorfman
Cool, Linux commands are always awesome.
I just Added*.qmlto the command so i can include qml also for the line count.find . -type f -iname \*.h -o -iname \*.hpp -o -iname \*.qml -o \ -iname \*.c -o -iname \*.cc -o -iname \*.cxx \ -o -iname \*.cpp | \ xargs -n 1 egrep -v "^[ \t]*$" | wc -lThanks a lot again
@mrjj @Eddy @jsulm @J-Hilk @Kent-Dorfman @aha_1980 @wrosecrans .Have a great day.
