My guess is that it is a problem with the compiler options you are using, the compiler itself, or the file system. I just now compiled both versions (with optimizations on) and ran them against a 92,000 line text file: c++ version: 113 ms c version: 179 ms And I suspect that the reason that … Read more
Open the search dialog box and write :- Find: ^.*$ Replace: $0\n$0
Find \R and replace with empty string. \R matches multiple linebreak styles, including most common \r\n and \n. Search Mode must be set to Regular expression.
Use tail: tail -n+3 file from the man page: -n, –lines=K output the last K lines, instead of the last 10; or use -n +K to output lines starting with the Kth
lines_per_file = 300 smallfile = None with open(‘really_big_file.txt’) as bigfile: for lineno, line in enumerate(bigfile): if lineno % lines_per_file == 0: if smallfile: smallfile.close() small_filename=”small_file_{}.txt”.format(lineno + lines_per_file) smallfile = open(small_filename, “w”) smallfile.write(line) if smallfile: smallfile.close()
Most of the answers already here seem to follow the general idea that: find the intersection of two straight lines passing the given points. determine if the intersection belong to both line segments. But when intersection does not occur often, a better way probably is to reverse these steps: express the straight lines in the … Read more
I found a nice one liner here >> http://www.pixelchef.net/remove-empty-lines-file-powershell. Just tested it out with several blanks lines including newlines only as well as lines with just spaces, just tabs, and combinations. (gc file.txt) | ? {$_.trim() -ne “” } | set-content file.txt See the original for some notes about the code. Nice 🙂
Ctrl+Shift+F will format a file in Eclipse, breaking long lines into multiple lines and nicely word-wrapping comments. You can also highlight just a section of text and format that. I realize this is not an automatic soft/hard word wrap, but I don’t think the question was asking for anything fancy.
You just have to set a number of lines in your TextView like this: android:maxLines = “10” and you must also add: android:minLines=”1″ The rest of this not necessary if you are not using scrolling and a property which says that this TextView should be scrollable vertically: android:scrollbars = “vertical” And in your Java-code: yourTextView.setMovementMethod(new … Read more
When working with XNA, everything (even 2d primitives) have to be expressed in a way that a 3d card can understand, which means that a line is just a set of vertices. MSDN has a pretty good walkthrough here: http://msdn.microsoft.com/en-us/library/bb196414.aspx#ID2EEF You’ll find that it takes more code to render a primitive line than it would … Read more
