I want to be able to have two Haml elements on the same line. For example:
%h1 %a{:href => '/'} Professio.
That doesn't work. How would I get something like this to work without borking?

I use the command line sqlite3 executable to check queries I make from my code.
Is there a way to read in pragma statements or other session setup (".mode csv" for example) when the executable starts up?
I know I can do a ".read " once I'm in, but that's tedious.
Hello everyone,
How can I get the file name and line number in python script.
Exactly the file information we get from an exception traceback. In this case without raising an exception.
Hi,
I am using the code from this tutorial to parse a CSV file and add the contents to a database table. How would I ignore the first line of the CSV file? The controller code is below:
def csv_import
@parsed_file=CSV::Reader.parse(params[:dump][:file])
n = 0
@parsed_file.each do |row|
s = Student.new
s.name = row[0]
s.cid = row[1]
s.year_id = find_year_id_from_year_title(row[2])
if s.save
n = n+1
GC.start if n%50==0
end
flash.now[:message] = "CSV Import Successful, #{n} new students added to the database."
end
redirect_to(students_url)
end
Hi,
I'm using this code now
echo $form-input('username');
How do I make sure the label shows up on a different line than the input field?
I managed to imitate what I'm trying to do, just want to make sure that I'm using it the right way.
echo $form-label('username', 'Username');
echo $form-input('username', array('label' = 'false'));
Thanks,
Tee
Is there any plugin to some IDE that show the number of times a line is run in the code?
Eclipse's ECLemma does not seem to have a setting to show execution times at the left-hand-side bar, like in the service WebCat.
Hi, I am wondering what this line of code mean?
b = (gen_rand_uniform()>0.5)?1:0;
The gren_rand_uniform() is a function to generate random 0 and 1 numbers. However I don't get the meaning for >0.5 and 1:0.
I know this is supposed to be a basic question, please bear with me.
Thanks!

I am pulling data into my iphone application using xml. The xml value is then placed in a variable.
example variable:
123 London road \n London \n England
The variable is then set as a label.
I want the line breaks to appear in the label, instead it is printing \n.
If i manually set the label value
locationLabel.text = @"123 London road \n London \n England"
It works as i want it to.
Can anyone explain this?
I am trying to get a table of icons appear on the same line as the header.
In the HTML below, the icons appear on a separate line.
I tried using 'top' attribute to move the table, but this is not a good solution because then there's an ugly space between the icons table and the rest of the document. How can I fix this?
<html>
<head>
<style type="text/css">
#action-icons
{
float:right;
position:relative;
border:0;
}
</style>
</head>
<body>
<h1 class="edit">Bla bla</h1>
<table id="action-icons">
<tbody>
<tr>
<td><img width="64" height="64"/></td>
<td><img width="60" height="60"/></td>
</tr>
<tr>
<td><img width="36" height="36"/></td>
<td><img width="36" height="36"/></td>
</tr>
</tbody>
</table>
<table width="100%" class="tasksgrid">

<tr>

<th class='taskcell'>Two</th>

I am trying to create a Exception class to get and send errors from client to server. I want to catch exception in javascript function and push the details to the web service to write to database.

I have dictionary like
d = {'user_id':1, 'user':'user1', 'group_id':3, 'group_name':'ordinary users'}
and "mapping" dictionary like:
m = {'user_id':'uid', 'group_id':'gid', 'group_name':'group'}
All i want to "replace" keys in first dictionary with keys from second (e.g. replace 'user_id' with 'uid', etc.)
I know that keys are immutable and i know how to do it with 'if/else' statement.
But maybe there is way to do it in one line expression?
I have a bunch of text files where I want to add a line ending after each period.
I'm wondering if there is a way to do this by doing replacing all periods with a \n\n, assuming I have the right encoding (unix).
Anyone know how I would do this? Replace .'s with \n\n and then save as a different file?
Thanks!
Hello:
How can I break long lines when writing c++ code in vim? For example, if I have something like

:56:25: warning: missing terminating " character
:56: error: missing terminating " character
:57: error: stray ‘\’ in program
:57:37: warning: missing terminating " character
:57: error: missing terminating " character

I'm trying to read a comment that is stored in a mysql table. For some reason I always get a parse error on the last line of the file even if the last line is blank. I'm not sure if it's relevant but the connect.php works for putting the comment into the database. I'm using wampserver to host it and coding it by hand.
I think that's it's something to do with the while loop, when I comment out the while(){ and the } near the end I just get a few missing variable errors as you would expect. I'm quite new to php coding so I'm pretty sure the problem will be something simple that I've either missed or not understood properly.
Anyway, here's my code:
<?php
include "connect.php";
?>
<?php
$sql = "SELECT * FROM main";
$result = mysql_query($sql) or die("Could not get posts from table");
while($rows=mysql_fetch_array($result)){
?>
<table bgcolor="green" align="center">
<tr>
<td></td>
</tr>
<tr>
<td><strong> <? echo $rows['name']; ?> </strong></td>
</tr>
<tr>
<td> <? echo $rows['email']; ?> </td>
</tr>
<tr>
<td> <? echo $rows['comment']; ?> </td>
</tr>
</table>
<?
}
?>
Thanks for the help. :)
Is there a way to reconstruct the command line arguments passed to Java within a Java program, including the JVM options and classpath option?
I have a Java program that needs to restart the JVM and manipulate its bootclasspath (i.e. trying to override some system classes). I use the libc system method to invoke the new JVM.
I'm open for better approaches, but Java agents isn't an option.
Hello,
I am using a regular expression search to match up and replace some text. The text can span multiple lines (may or may not have line breaks).
Currently I have this:

Get-ChildItem -exclude *.bak | Where-Object {$_.Attributes -ne "Directory"} |ForEach-Object {
$text = [string]::Join("`n", (Get-Content $_))
$text -replace $RegEx ,"REPLACED"}

How can view the execution line used by netbean v6.8 to execute my java application when I press the run program button (right pointing green arrow)? I'm looking for something like:
java -cp build/class Main
I'm trying to make the jump to java IDE developement from 15 years writing c and c++ with vi. I'm starting with netbean since it seems to have the best vi key bindings.
Lets us consider the following program :
#include <stdlib.h>
int main(int argc, char **argv){
int a,b;
if (argc != 3)
return -1;
a = atoi(argv[1]);
b = atoi(argv[2]);
a = b ? a/b : 0;
return a;
}
The task is to crash the program by providing arguments in command-line.
