this is off the hook!
HAI CAN HAS STDIO? PLZ OPEN FILE "LOLCATS.TXT"? AWSUM THX VISIBLE FILE O NOES INVISIBLE "ERROR!" KTHXBYE
they actually have a few test interpreters for it and more examples here.
today, i wanted to try out my test arabic gtk program to see if behdad’s new changes to pango magically fixed the renown arabic shaping issue [in short, it had nothing to do with it]. anyway, i discovered that i needed to install libquran, and to make a long story short, my test program, which used to work before, segfaulted. i ran gdb and valgrind only to find the segfault happening within libquran at the closing of the configuration file (noting this libquran code hasn’t been changed in 3 years now).
i looked at the source, and discovered that the file pointer was becoming null after a call to getline. i tried to see if i could reproduce this in a smaller test program, and i discovered that i indeed could -
#include <stdio.h>
int main(void){
int n = 0;
char* tmp;
FILE* fp = fopen("./testfile", "r");
getline(&tmp, &n, fp);
printf("got a str of: %s\n", tmp);
printf("now fp is: %s\n", (fp==NULL)? "null" : "not null");
fclose(fp);
free(tmp);
return 0;
}
the program displayed the first line from testfile, but unexpectedly displayed that fp is null and segfaulted at the fclose. checking the return from getline, i see that it returns successfully (the number of characters it read).
while i got around this problem by modifying the library to do a malloc followed by an fgets, i am just confused -this library code hasn’t been touched in 3 years, it used to work before, and i just repulled it from cvs when i discovered this. so why is it broken now? the only thing that i can think of being different is that my box now runs a 64 bit version of linux, but would that break it?
any ideas?
one of my coworkers sent me this today. pretty funny that they blatantly ripped off the images and such. on a similar note, it seems as though there’s way too much red tape to go through in order to get something like this officially done.
today, i went to the supermarket to buy some stuff, and i picked up a 12 pack of pepsi on the way out. when i looked at my receipt, i noticed that there was an additional tax of $0.48 for the pepsi, separate from the overall tax at the bottom (not sure if it is included in the overall x% tax that you pay at the end or not, but regardless, it is more).
oddly enough, i could buy 1.92 cans of pepsi for the amount of the tax. actually, for the total of $3.98, i could have bought 15.92 cans from the vending machine at work… (although ideally, i should stop drinking pepsi altogether).
i’ve recently been playing more and more with ruby and i really like it. at the same time, i’ve been loving launchy, an open source application launcher for windows (currently using it on my work laptop).
since i love launchy so much, i started to wonder, “why not write something similar for linux?” – now i know one will say that deskbar does the job, but its not quite the same. so anyway, because i wanted transparency and so on, i decided to look into cairo, and the rcairo ruby bindings.
here’s a screenshot of what i’ve been playing with so far:
note the very right side is the part showing of my open gvim window. while i have yet to organize the code and start writing it for real, the ruby file i have is a proof of concept of all the required pieces i can think of (cairo wise anyway) working together.
