Summary : SQLite is a C library that implements an embeddable SQL database engine
Name : sqlite
Version : 3.6.4
Release : 1
License : Public Domain
Vendor : Sqlite
Packager : Kannaiyan
Group : System/Libraries
Source : %{name}-%{version}.tar.gz
BuildRoot : %{_tmppath}/%{name}

%Description
SQLite is a software library that implements a self-contained, serverless,
zero-configuration, transactional SQL database engine.
Programs that link with the SQLite library can have SQL database access
without running a separate RDBMS process. The distribution comes with a
standalone command-line access program (sqlite) that can be used to
administer an SQLite database and which serves as an example of how to
use the SQLite library.

Pattern Matching with PCRE Library

Pattern matching is wonderful with Perl and when it is comes to C it is nice to build wonderful applications.

#include <ctype.h>
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <time.h>
#include <locale.h>
#include <errno.h>
#include <pcre.h>

int main(int argc,char *argv[])
{
pcre *re;
char cgets[250];
const char *error;
int erroffset;
int retexec;
re = pcre_compile("^(gnayiru|thingal|chevvai|budhan|viyazhan|velli|sani)$",0,&error,&erroffset,NULL);
if( re )
{
while(1){
printf("Enter the details you wish to match:");
fgets(cgets,250,stdin);
cgets[strlen(cgets)-1] = '\0';
retexec = pcre_exec(re,NULL,cgets,strlen(cgets),0,PCRE_PARTIAL,NULL,0);
switch( retexec)
{
case PCRE_ERROR_NOMATCH:
printf("No Matches\n");
break;
case PCRE_ERROR_PARTIAL:
printf("Partial Match\n");
break;
case 0:
printf("Perfect Match\n");
break;
default:
printf("Error Code: %d\n",retexec);
break;
}
}
} else {
printf("Error in Regex Compilation");
}
}


Output here:

Getting DNS SRV Records for voip through PHP

It is important for the internet service to automatically locate the services at the moment. Just use this code to get the voip protocols service records from the DNS servers.

#!/usr/bin/php
< ?php


$domain = "pulver.com";

$voipprotocol = array("sip","iax");
$transportproto = array("udp","tcp");

foreach($voipprotocol as $voipprot)
{
foreach($transportproto as $trprot)
{
$voipdomain = "_" . $voipprot . "._" . $trprot . "." . $domain;
echo "Searching $voipdomain\n";
$rootinfo = dns_get_record($voipdomain,DNS_ALL, $nsinfo, $addinfo);
//print_r($rootinfo);
foreach($rootinfo as $srootinfo)
echo strtoupper($voipprot) . " " . strtoupper($trprot) . " HOST: " .
$srootinfo['target'] . ":" . $srootinfo['port'] . "\n";
}
}

?>

You can download using svn with the following command,

svn co http://codeoftheday.googlecode.com/svn/trunk/18Aug2007

Do Let me know if there are any improvements done, will keep updated.

Enjoy.

If you want to get this done under C, you can look into the ruli library.

Convert header file tree to source file tree - Shell Script

It is usual practice to write header files first and then the source code. We usually need to go back an forth to get the header file name to start to go with the coding for enterprise projects.

Using the following command, you can convert the header tree to source tree.

find ./include -ls | awk '{print($3,$11);}' | cut -c1,11- | awk '{print($2,$1)}' | sed -e 's/^\.\/include//g' | awk '{if( $2 != "" ) print($1,$2);}' | awk '{if($2 == "d") printf("\"mkdir -p ./src%s\"\n",$1); else{ sub(/\.h$/,".cpp",$1); printf("\"touch ./src%s\"\n",$1);}}' | xargs | /bin/sh

replace .cpp with the extension you want.

It looks like

./include
|----dir1
|------- dir2
|-----------file.h
etc.,

./src
|--------dir1
|-----------dir2
|------------ file.cpp

All header files will replaced with their equivalent name in .c or .cpp with the extension you supply in the command.


Enjoy.

Find and Replace string in files under linux directory tree - Linux Shell Script

This is one of most used command in linux to replace the string in files.

find . -name "*.cpp" | xargs grep -l stringtofind | xargs sed -i s/stringtofind/stringtoreplace/

Code to generate Unique Random Numbers - PHP

I was looking for a Unique Random Number with different length to use it for one of the calling card company. This PHP script just rocks. Enjoy, download the code from svn rather than copy and paste.

#!/usr/bin/php

function generateuniquenumbers($len,$count,$includezero=1)
{

if( strlen($count) > $len )
{
echo "Looks something funny in the parameter which you have supplied. \n";
return ;
}
echo "Generating " . $count . " numbers with length " . $len . "\n";
$mult = 0;
$fract = 0;
$numbers[] = "";
mt_srand(10);
if( $len > 9 )
{
$mult = (int)($len/9);
$fract = (int) $len % 9;
} else {
$fract = $len;
}
if( $fract > 0 )
{
$minfract = "";
$maxfract = "";
for($m=0; $m<$fract; $m++)
{
if($includezero)
$minfract = "0";
else
$minfract .= "1";
$maxfract .= "9";
}
}

for($numcount=0;$numcount<$count;$numcount++)
{
$curnumber = "";
for($i=0;$i<$mult;$i++)
{
if( $includezero )
$currand = mt_rand(0,999999999);
else
$currand = mt_rand(111111111,999999999);
if( strlen($currand) <>
{
$templen = strlen($currand);
for( $pad = 9 - $templen; $pad > 0; $pad--)
$curnumber .= "0";
}
$curnumber .= $currand;
}
if( $fract > 0 )
{
$currand = mt_rand($minfract,$maxfract);
if( strlen($currand) <>
{
$templen = strlen($currand);
for( $pad=strlen($maxfract)-$templen;$pad > 0;$pad--)
$curnumber .= "0";
}
$curnumber .= $currand;
}
if( !in_array($curnumber,$numbers) )
{
$numbers[] = $curnumber;
}
else
$numcount --;
}
return $numbers;
}

$ncount = 20;
$nlength = 20;

$numbers = generateuniquenumbers($nlength,$ncount,0);

for($k=1;$k<=$ncount;$k++)
echo $numbers[$k] . "\n";

?>
