BCS c++ App That Creates Eclipse c++ Project And Class

This application accepts a workspace path, family id and class name to create a fully functional Eclipse Oxygen c++ project.

After this application executes the developer should import the newly created project into the Eclipse Oxygen IDE for c++ and continue developing the application.

Initially all libraries for GTK3+ (via gtkmm), Boost and other capabilities are available as well as some custom routines which are useful for in the design and coding of c++ applications.

What is generated is the complete project development environment and the source code for the mainline as well as aforementioned class.  This is accomplished by using a completed project as a template  while simultaneously creating and naming all component parts based on the family id and the class name provided.

Below is the structure to suppling input to the application.

struct gen_params {
	string projHome = "/home/archman/workspace/cpp/";
	string famId = "Gen01";
	string clas = "cl01";

Here is the main flow for accomplishing this task.

void utils::gen02(gen_params gp) {
	cout << "In Gen 02" << endl;
	utils::forceDirectories(gp.td + "Debug");
	utils::forceDirectories(gp.td + "src");
	utils::forceDirectories(gp.td + ".settings");
			gp.td + ".cproject");
			gp.td + ".project");
	utils::fileCopy("/home/archman/workspace/cpp/skelp/.settings/language.settings.xml", gp.td + ".settings/language.settings.xml");
	utils::fileCopy("/home/archman/workspace/cpp/skelp/Debug/makefile", gp.td +"Debug/makefile");
	utils::fileCopy("/home/archman/workspace/cpp/skelp/Debug/objects.mk", gp.td +"Debug/objects.mk");
	utils::fileCopy("/home/archman/workspace/cpp/skelp/Debug/sources.mk", gp.td +"Debug/sources.mk");
	utils::forceDirectories(gp.td + "Debug/src/");
	utils::fileCopy("/home/archman/workspace/cpp/skelp/Debug/src/subdir.mk", gp.td +"Debug/src/subdir.mk");
	mod_rec mr;
	utils::init_repl(mr, gp);
	string str[sizeOfStringArray];
	int lcnt;
	lcnt = utils::fin("/home/archman/workspace/cpp/skelp/src/skelp.cpp", str);
	utils::upd(mr, str, lcnt);
	utils::fot(gp.td + "src/" + gp.famId + "p.cpp", str, lcnt);
	lcnt = utils::fin("/home/archman/workspace/cpp/skelp/src/skelh.h", str);
	utils::upd(mr, str, lcnt);
	utils::fot(gp.td + "src/" + gp.famId + "h.h", str, lcnt);
	lcnt = utils::fin("/home/archman/workspace/cpp/skelp/src/skelh.cpp", str);
	utils::upd(mr, str, lcnt);
	utils::fot(gp.td + "src/" + gp.famId + "h.cpp", str, lcnt);

The following structure identifies the replacement values from the skeleton template to the newly generated source code.

void utils::init_repl(mod_rec& mr, gen_params gp) {
	mr.numPair = 3;
	mr.mp[0].from = "skelp";
	mr.mp[0].to = gp.famId + "p";
	mr.mp[1].from = "skelh";
	mr.mp[1].to = gp.famId + "h";
	mr.mp[2].from = "SKELH";
	mr.mp[2].to = boost::to_upper_copy(gp.famId + "h");
	mr.mp[3].from = "utils";
	mr.mp[3].to = gp.clas;

The workhorse to the application is the section of code listed below.

void utils::upd(mod_rec rmrp, string stv[sizeOfStringArray], int cnt) {
	int ii = rmrp.numPair;
	string rline;
	int j = 0;
	while (j < cnt) {
		int i = 0;
		while (i <= ii) {
			boost::replace_all(stv[j], rmrp.mp[i].from, rmrp.mp[i].to);
		rline = stv[j];

The initial loop goes through each line of source code in the subject file. The innermost loop iterates from the first replacement pair until the last replacement pair is processed. This process is repeated until all lines in the subject source code is processed.
