  • Example compilers

    - by saf
    I'm searching for the source code of a compiler capable of creating Win32 programs from an input program in a programming language (It doesn't matter which, maybe the simpler the better) Yet I can't find anything right for me and huge compilers like GCC make me extremely confused as they have so many features that I don't know where to start. Is there an OpenSource Win32 micro-compiler for some programming language out there I could take a look at?

  • NAN mixing float and GLFloat?

    - by carrots
    This often returns NAN ("Not A Number") depending on input: #define PI 3.1415f GLfloat sineEaseIn(GLfloat ratio) { return 1.0f-cosf(ratio * (PI / 2.0f)); } I tried making PI a few digits smaller to see if that would help. No dice. Then I thought it might be a datatype mismatch, but float and glfloat seem to be equivalent: gl.h typedef float GLfloat; math.h extern float cosf( float ); Is this a casting issue?

  • Perl: Edit hyperlinks in nested tags that aren't on separate lines

    - by user305801
    I have an interesting problem. I wrote the following perl script to recursively loop through a directory and in all html files for img/script/a tags do the following: Convert the entire url to lowercase Replace spaces and %20 with underscores The script works great except when an image tag in wrapped with an anchor tag. Is there a way to modify the current script to also be able to manipulate the links for nested tags that are not on separate lines? Basically if I have <a href="..."><img src="..."></a> the script will only change the link in the anchor tag but skip the img tag. #!/usr/bin/perl use File::Find; $input="/var/www/tecnew/"; sub process { if (-T and m/.+\.(htm|html)/i) { #print "htm/html: $_\n"; open(FILE,"+<$_") or die "couldn't open file $!\n"; $out = ''; while(<FILE>) { $cur_line = $_; if($cur_line =~ m/<a.*>/i) { print "cur_line (unaltered) $cur_line\n"; $cur_line =~ /(^.* href=\")(.+?)(\".*$)/i; $beg = $1; $link = html_clean($2); $end = $3; $cur_line = $beg.$link.$end; print "cur_line (altered) $cur_line\n"; } if($cur_line =~ m/(<img.*>|<script.*>)/i) { print "cur_line (unaltered) $cur_line\n"; $cur_line =~ /(^.* src=\")(.+?)(\".*$)/i; $beg = $1; $link = html_clean($2); $end = $3; $cur_line = $beg.$link.$end; print "cur_line (altered) $cur_line\n"; } $out .= $cur_line; } seek(FILE, 0, 0) or die "can't seek to start of file: $!"; print FILE $out or die "can't print to file: $1"; truncate(FILE, tell(FILE)) or die "can't truncate file: $!"; close(FILE) or die "can't close file: $!"; } } find(\&process, $input); sub html_clean { my($input_string) = @_; $input_string = lc($input_string); $input_string =~ s/%20|\s/_/g; return $input_string; }

  • XNA/C# Game Settings (Menu?)

    - by PCAddict
    It's my first time trying to make anything really interesting in C# and I was trying to make a simple form or game screen where the user could define a custom resolution/screen ratio etc. or to automatically detect the max screen size/ratio and output? its my first game, so I was wondering if it was possible or if there would be any major issues with such, rather than just setting it to 1366x768 (the resolution of all of my computers). Thanks in advance for any assistance.

  • In paragraph form field with label underneath

    - by aslum
    I'd like to have an input box in the middle of a paragraph, with the label in smaller text underneath it. Kind of like: Hello [________________], This is to inform you (Customer Name) that the [____________] you ordered is no longer (Item Name) available. I thought it would be pretty easy to do, but my brain doesn't appear to be working today. Is it possible to do this with just CSS, and in a simple enough manner that it can be adapted to different forms easily?

  • Wordpress as CMS, Without Using It As Website Platform

    - by swt
    What is the best method, if there is one, of using Wordpress as a CMS for users to input data while not actually building the website on the Wordpress platform? One possible solution I've found is using a PHP class called "WPGet" (http://peter.upfold.org.uk/projects/wpget) which fetches directly from the database.
