• Are there web search engines with exact match or regex capabilities (for related terms)?

  - by naxa

  Every once in a while I come upon a situation when google's way of searching results in too broad results even if I enclose my search terms in quotation marks. For example now I've tried to find pages that contain both "py.path" and "path.py" without much success. I'm currently aware of engines|sites like Google Code Search for searching actual code and (apparently) Stackoverflow for searching QAs, symbolhound that lets me find symbols, and also wikipedia is often a good place to find lists of symbols. But none of these seems to perform very good in matching exactly on search term pairs (or tuples) and use a broad-enough segment of the web. Is there a website that is good with exactly finding search term pairs? (Why not?)

• Replace character between strings

  - by trembon

  Maybe it's just too late for me to do this, but I'm trying to replace a character between 2 string with regex in PHP. Example string: other | text [tag]text|more text|and more[/tag] end | text My goal is to replace | with <br/> between [tag] and [/tag]. Tried with this, seems it wasn't that easy though: /<td>(\|)<td>/gsi Searched a bit, but couldn't make out an answer with the stuff I found. Hope you can help, thanks

• How to ensure structures are completly initialized (by name) in GCC?

  - by Steven Spark

  How do I ensure each and every field of my structures are initialized in GCC when using designated initializers? (I'm especially interested in function pointers.) (I'm using C not C++.) Here is an example: typedef struct { int a; int b; } foo_t; typedef struct { void (*Start)(void); void (*Stop)(void); } bar_t; foo_t fooo = { 5 }; foo_t food = { .b=4 }; bar_t baro = { NULL }; bar_t bard = { .Start = NULL }; -Wmissing-field-initializers does not help at all. It works for fooo only in GCC (mingw 4.7.3, 4.8.1), and clang does only marginally better (no warnings for food and bard). I'm sure there is a reason for not producing warnings for designated initializer (even when I explicitly ask for them) but I want/need them. I do not want to initialize structures based on order/position because that is more error prone (for example swapping Start and Stop won't even give any warning). And neither gcc nor clang will give any warning that I failed to explicitly initialize a field (when initializing by name). I also don't want to litter my code with if(x.y==NULL) lines for multiple reasons, one of which is I want compile time warnings and not runtime errors. At least splint will give me warnings on all 4 cases, but unfortunately I cannot use splint all the time (it chokes on some of the code (fails to parse some C99, GCC extensions)). Note: If I'm using a real function instead of NULL GCC will also show a warning for baro (but not bard). I searched google and stack overflow but only found related questions and have not found answer for this specific problem. The best match I have found is 'Ensure that all elements in a structure are initialized' Ensure that all elements in a structure are initialized Which asks pretty much the same question, but has no satisfying answer. Is there a better way dealing with this that I have not mentioned? (Maybe other code analysis tool? Preferably something (free) that can be integrated into Eclipse or Visual Studio...)

• Gedit adds line at end of page

  - by Sam

  The answer to this must be somewhere but I'm not finding it -- can anyone help me understand why in Gedit, if I have a page of code there is no extra trailing blank line, but then when I do a file comparison for my svn commit it shows an extra line being added at the end of the file? I have a feeling that Gedit is automatically adding an ending line break. But why, I have no idea...

• Role of OSI layers when we open a url in browser?

  - by user2715898

  I have searched on this topic a lot but I am not able to understand how and where OSI layers (Application, Presentation, Session, Transport, Network, Datalink, Physical) come into picture in the whole process of opening a webpage in browser. I have read this - http://stackoverflow.com/questions/2092527/what-happens-when-you-type-in-a-url-in-browser?lq=1 and I know all the functions of all the layers that are there in OSI model. Also, do we use OSI model or TCP/IP in the whole process? Basically I am having problem linking all the things together. And please forgive me if there are resources out there that explain this concept. You can definitely point to them.

• Static variables within functions in C++ - allocated even if function doesn't run?

  - by John C

  I've been reading up on C++ on the Internet, and here's one thing that I haven't been quite able to find an answer to. I know that static variables used within functions are akin to globals, and that subsequent invocations of that function will have the static variable retain its value between calls. However, if the function is never claled, does the static variable get allocated? Thanks

• How to get number of entries in a Lua table?

  - by romkyns

  Sounds like a "let me google it for you" question, but somehow I can't find an answer. The Lua # operator only counts entries with integer keys, and so does table.getn: tbl = {} tbl["test"] = 47 tbl[1] = 48 print(#tbl, table.getn(tbl)) -- prints "1 1" count = 0 for _ in pairs(tbl) do count = count + 1 end print count -- prints "2" How do I get the number of all entries?
