regex - Regular Expression for nested tags (Wikimedia content) -

-

has not regex in a while, and will rust slightly.

I am trying to extract categories from Wikipedia entry. What I need is a personal string contained in a pattern that starts with two open brackets and ends with two closed parentheses. is.

This query works most of the time - 

  (? [? & Lt; grade & gt; * [^ \] #]) ( [\]]

But there are problems when they have a comma (',') in the closing brackets.

Its unfortunate result is that when the following text is parse 

  lower = = [[Seattle, Washington]], [[United States | United States]] |

This category " "Removes the following for 

  Seattle, Washington]], [[Joint United States | USA]

Clearly, the comma is blocking it and it is getting the next set. The best way to capture each value between open and closed double brackets. What is the problem?

The problem is not a comma, the problem is that . * Match will be "]] [[" Just with something else * is greedy - it will be as matchable as possible. -Lalachi Sons Karan can use has been suggested that (as), or . * [^ \]] * - Change anything of the greedy match leaving closing the bracket should also do the trick.

In addition, these are not "nested" tags - this will be [[tags [[inside]]] tags]] . Probably not what you want because I do not think this means in Wikimedia markup.

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
