programming languages - Why do you or do you not implement using polyglot solutions? -

-

polyglot, or multiple language, solutions allow apply languages problems best suited for. yet, @ least in experience, software shops tend want apply "super" language aspects of problem trying solve. sticking language come "hell or high water" if language available solves problem , naturally. why or not implement using polyglot solutions?

i advocate more 1 language in solution space (actually, more 2 since sql part of many projects). if client likes language explicit typing , large pool of talent, advocate use of scripting languages administrative, testing, data scrubbing, etc.

the advantages of many-language boil down "right tool job."

there legitimate disadvantages, though:

  • harder have collective code ownership (not versed in languages)
  • integration problems (diminished in managed platforms)
  • increased runtime overhead infrastructure libraries (this significant)
  • increased tooling costs (ides, analysis tools, etc.)
  • cognitive "bumps" when switching 1 another. double-edged sword: well-versed, different paradigms complementary , when problem arises in 1 there "but in x solve z!" , problems solved rapidly. however, don't quite grok paradigms, there can real slow-down when trying comprehend "what this?"

i think should said if you're going go many languages, in opinion should go languages different approaches. don't think gain in terms of problem-solving having, say, both c# , vb on project. think in addition mainstream language, want have scripting language (high productivity smaller , one-off tasks) , language different cognitive style (haskell, prolog, lisp, etc.).

right now, have tool tip pops when hover on edit box. problem tool tip contains multiple error messages , in 1 long line. need have each error message on own line. error messages contained in cstring new line seperating them. my existing code below. bool ontooltiptext(uint, nmhdr* pnmhdr, lresult* presult) { assert(pnmhdr->code == ttn_needtexta || pnmhdr->code == ttn_needtextw); // need handle both ansi , unicode versions of message tooltiptexta* pttta = (tooltiptexta*)pnmhdr; tooltiptextw* ptttw = (tooltiptextw*)pnmhdr; // tchar szfulltext[256]; cstring strtiptext=_t(""); uint nid = pnmhdr->idfrom; if (pnmhdr->code == ttn_needtexta && (pttta->uflags & ttf_idishwnd) || pnmhdr->code == ttn_needtextw && (ptttw->uflags & ttf_idishwnd)) { // idfrom hwnd of tool nid = ::getdlgctrlid((hwnd)nid); } //m_errprojaccel[ch] contains 1 or more error messages each...
