removeEnters


#Purpose to remove the Enters from the Windows Clipboard while
#copy pasting large bunches of text from pdf files
#tested on WinXP and WinVista. Hint put a shortcut on the Desktop and assign keyboard
#shortcuts mine is AltGr + R

package removeEnters ;
use strict ;
use warnings ;

use Win32::Clipboard ;

main(); #action !!!

sub main
{
local $/; # enable localized slurp mode
my $text = Win32::Clipboard::Get(); #get the text from the clipboard

#added the logic to remove the enters only in paragraphs
#todo what about the enters after lists ?! requires some backtracking
$text =~s/\r\n([a-z])/ $1/g ; #remove the enters out of it
$text=~s/(—End—|ATTENTION)/\n\n$1\n/g ;
print "the text is \n" ;

setting up Drupal development environment on Windows XP

1. Download and install WAMP
- http://www.wampserver.com/en/download.php (or google download WAMP
2. Download and install Drupal
- Start with tutorial --- http://drupal.org/node/176025
- http://drupal.org/files/projects/drupal-x.x.tar.gz , choose version , download
- unzip the folder to C:\wamp\www , so that the following folder C:\wamp\www\drupal-5.2
structure should be available
3. Start the WAMP
Start - Programs - WAMP Server - start Wamp Server
- check functionality firefox http://localhost/
- start sqllite manager firefox http://localhost/sqlitemanager/
- login with the default root for the database cd "C:\wamp\mysql\bin" , mysql -u root mysql
4. Create the database (C:\wamp\www\drupal-5.2\INSTALL.mysql.txt
- logon to mysql CLI mysql -u root -p

NOTE: THE COMMAND ENDS AT THE MYSQL PROMT WITH ; NOT SIMPLY ENTER
- command to create the database
GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER, CREATE
TEMPORARY TABLES, LOCK TABLES
ON first.*
TO 'username'@'localhost' IDENTIFIED BY 'pass';

Query OK, 0 rows affected (0.01 sec)

- flush the previliges
FLUSH PRIVILEGES;

Query OK, 0 rows affected (0.01 sec)

5. Run the install script

firefox http://localhost/drupal-5.2/install.php?profile=default

6. Create the database for the Drupal installation
- in the mysql prompt -- create database dbDrupal;
- show all created databases --- show databases;
-
7. Fill up the textfields on the site with the data used so far:
Database name: dbdrupal
Database username: username
Database password: pass
press Save configuration : You should see the
Drupal installation complete

8. Procede with http://localhost/drupal-5.2/
- check the Drupal status http://localhost/drupal-5.2/?q=admin/logs/status
- some problems are displayed , click on files , click on create the following structure is created C:\wamp\www\drupal-5.2\files

9. How to change the password for a user in mysql prompt
mysql default username is root and default pass is mysql
so one has to login with the following command mysql -u root and type the password mysql when prompt
SET PASSWORD FOR 'root'@'localhost' = PASSWORD('newVerySecrtePass');

10. Annoyed for searchiing for the path of mysql -- add C:\wamp\mysql\bin to the path

11. Go to http://localhost/drupal-5.2/
- Configure your website
- create admin root , pass Extremely secret
- go to administration section , configure other users
-

edit locally , run on the server

This is constrained implementation of an broader idea. First the idea consisting of the following:
- to be able to work locally (e.g. on a Windows PC with TextPad )on an entire project of any type of source files - e.g. Perl, Java , C++ , etc.
- to be able to check for syntax errors with one keyboard shortcut on the server environment - e.g. one shortcut would upload the entire project on the server and call the syntax checking command, as well as get the possible errors or success messages and bring them back to the TextPad's environment for jump to error line
- to be able to run the whole project (with any possible parameters ) with receiving any possible ok and / or error messages

So far my implementation is combariably small , but it works using winscp as the file transfer and server side command execution tool.

Any thoughts would be appreciated ... Code:

#=============================PERL_TOOL_FOR_CALLING_WINSC_START
package upDown ;
use warnings ;
use strict ;
#Docs at the end ..


sub main
{
my $self = shift ;
my $cmd ="winscp /console userName\@server.com /script=winscp_scripit.pl" ;
`$cmd` ;
for ( "./ok.log" , "./error.log" )
{ dumpFile($self , $_ );
}
} #of main

sub dumpFile
{
my $self = shift ;
my $file = shift ;
open (FILE,$file);
my @rows = ;
foreach my $line (@rows) { print "$line" ; }
close (FILE);
}

main(); #action!!!


1;

__END__

#Purpose:
# Upload the code file , run the command on the server
# Download the command results , echo them from this script
#to be captured by the TextPad for jumping to the error row
#PREREQUISITES Windows + winscp + configured session
#Textpad + configured the following option Ctrl + 7 , perl $FileName
#Capture output , Regex: ^.+at (.+) line ([0-9]+)[.,]? , $FileDir , $
#TODO :
# - parametrize the code file name
# - how about a whole file folder project - e.g. uploading recursively ....
# - parametrize session name
#=============================PERL_TOOL_FOR_CALLING_WINSC_END
#=============================WINSCP_SCRIPT_START
#winscp_scripit.pl
#Note: the *. pl fileext is just for the Perl syntax highlighting ... you should have winscp in your path
#This file should be in the same dir as the Perl tool
# Automatically answer all prompts negatively not to stall
# the script on errors
option batch on
# Enable overwrite confirmations that conflict with the previous
option confirm on
# Change remote directory
cd /home8/24/userName/var
# Force ASCII mode transfer
option transfer ASCII
#upload the file
put C:\temp\temp\sendPerlMail.pl
call perl sendPerlMail.pl 1>ok.log 2>error.log
# Download file to the local directory d:\
#get both the logs \ to the end of the folders!!!
get ok.log C:\temp\temp\
get error.log C:\temp\temp\
#delete the logs
call rm -f error.log
call rm -f ok.log
# Disconnect
close
# Exit WinSCP
exit
