While this isn't a total answer, I can point out a few things.
In particular, tclsh
is quite happy under Windows; it's a major supported platform. The main problem that could happen in practice is if you pass a filename with a space in it (this is distinctly more likely under Windows than on a Unix due to differences in community practice). However, the execute()
as you have written it has no problems. Well, as long as tclsh
is located on the PATH
.
The other main option for integrating Tcl script execution with Qt is to link your program against the Tcl binary library and use that. Tcl's API is aimed at C, so it should be pretty simple to use from C++ (if a little clunky from a C++ perspective):
// This holds the description of the API
#include "tcl.h"
// Initialize the Tcl library; *call only once*
Tcl_FindExecutable(NULL);
// Make an evaluation context
Tcl_Interp *interp = Tcl_CreateInterp();
// Execute a script loaded from a file (or whatever)
int resultCode = Tcl_Eval(interp, "source test.tcl");
// Check if an error happened and print the error if it did
if (resultCode == TCL_ERROR) {
std::cerr << "ERROR: " << Tcl_GetString(Tcl_GetObjResult(interp)) << std::endl;
}
// Squelch the evaluation context
Tcl_DeleteInterp(interp);
I'm not a particularly great C++ coder, but this should give the idea. I have no idea about QProcess::execute()
vs std::system()
.
