Vimscript - Programmatically get colors from colorscheme - editor

I'm trying to create an autocmd in Vimscript which sets a few attributes of the colorscheme as I want them. Specifically, I'm trying to make the NonText background have the same color as the regular background.
The problem is, I have no idea how to get a colorscheme's background color from within vimscript.
Anyone have any ideas?
Edit:
So here's what I'm trying to achieve. Actually a few things:
Originally, I was trying to hide the "~" that's in front of all non-existant lines. Someone suggested setting it as the same color as the background, so I added an autocmd that did this: hi NonText guifg=bg.
After doing that, I realized that some colorschems have a different background color for the regular lines and the "non-existant" part of the buffer. This is a problem, since my autocmd sets the NonText color to be the same as the regular background, not the special "non-existant" background.
Also, I decided that even without the whole "get rid of the ~" issue, I don't like it when the non-existant parts of buffers are a different color.
Lastly, I'm trying to learn about vim colorschemes in general, since I'm planning to write a plugin that will need some other tricks like figuring out the colors from schemes.

There are two approaches here:
Use hi NonText. Not alone, but with :redir, of course. I won’t describe it more verbose because I personally don’t like any solution using :redir for a number of reasons (they are: 1. requires parsing 2. no nested redirections 3. no way to know whether redirection is active).
Use synIDattr() and hlID():
let bgcolor=synIDattr(hlID('NonText'), 'bg#')
will assign something in form "#rrggbb" (just "N" in terminal) to variable bgcolor, or -1 if background was not defined for this group. You can use this to construct :hi command (regular background should be defined in Normal group).
Just use
hi link NonText Ignore
. Works unless your colorscheme has redefined Ignore group so that it actually is shown.

hi NonText guibg=bg
How about that?
EDIT after clarification from the OP:
Okey, let's go from the start. For now I'd put writing of a plugin on hold for a while until you get acquinted with the basic Vim settings and language. The characters, one of which is the ~ you're trying to hide, are so called list characters, and they can be defined in the listchars option. What yours are you can see by set listchars?. They can also be turned on/off (visible or invisible, I mean) by either set list / set nolist, or toggled on/off with set invlist.
The NonText highlighting group is the one that "covers" the display of those characters, but really the way to turn them on/off is via the setting, not via overwriting the background/foreground color of that group. Therefore my original confusion over your intentions. There is also a highlighting group SpecialKey that you might also find interesting, since it cover some cases.

How to copy class and function name in Blackfire report

When I am copy-pasting method name from Blackfire profile, I am getting a reversed string like this:
sgnitsiLredivorPdaol::yrotisopeRresopmoC\yrotisopeR\resopmoC
What is intended way to copy a proper method name (not reversed)?
Why does Blackfire has such behaviour? Is this some kind of stupid joke or copy-paste protection?
This is indeed a UX issue we currently have in Blackfire, let me explain it to you:
We want to display the end of the namespace/classname value in this part of the interface
We want to have a text-overflow ellipsis on the left part of the value.
Unfortunately, using text-overflow: ellipsis on the left of the text is not supported by modern browsers at the moment.
There are two ways to do that: Either know the width of the text, work with a fixed width column and truncate programmatically or use a hack, revert the letters, change the text direction from left-to-right to right-to-left locally and use traditional text-overflow.
As we deal with a resizable UI here, we chose the second option, and this is the one that provide the better experience at the moment. However, as you notice, this issue remains.
We're thinking about a fix for this issue. It might be with the Clipboard API.
In the meantime, here's the way you can copy/paste the value :
Just expand a node and copy from the inner box, see:
Hope it helps you until we find a better solution.

Add alternative text to a phrase in a document file

I use LibreOffice Writer and I want to insert an alternative text to a specific phrase in the document, how can I do it?
Example if we have an image in the document we can make double left click and add the alternative text like this:
Is it possible to make the same if we select a whole phrase of text? If yes how? And if No is there any other proposal?
The alternative text in 'word'/odt documents is actually intended as the 'alt' attribute in HTML (web) pages:
The alt attribute provides alternative information for an image if a
user for some reason cannot view it (because of slow connection, an
error in the src attribute, or if the user uses a screen reader).
(http://www.w3schools.com/tags/att_img_alt.asp)
It's only purpuse is thus to provide the user with information in case he/she can not view the image. Since having alternative text in case some text cannot be displayed is, well, silly, this 'alt' attribute is not defined for pieces of text. Alternatively, you could have a hyperlink pointing to nothing ("#"), which does provide a tooltip attribute.
What is it that you're intending to achieve anyway? It's not going to show up on any prints, which is the intended purpose of Writer... Footnotes (for prints) or Comments (for communication with co-editors) might suit you better.

Amending Translation Values in CRM 2011 Outside of the Translation Files

I have received a requirement to amend the translations of the 'Add new..' and 'Add existing..' buttons in French. A typical default button is shown below:
The desired new translations are essentially to remove the gender neutrality (if my rather poor school French is correct!). So rather than 'Ajouter un(e)' we have 'Ajouter un'.
Unfortunately these button labels are not included in the standard translations file (Settings -> Customisations -> Export Translations).
Are there any other options available? Given the nature of the requirement, I am happy to consider pretty much any kind of hack. CRM must be generating these values from somewhere, any ideas where they are hidden?
Note: I profoundly disagree with this requirement for fairly obvious reasons and I am sure most people reading this question will as well. However, requirements are what they are and sometimes customers/clients just will not budge. This is one of those cases.
You can define the labels for CRM Ribbon controls. See Use Localized Labels with Ribbons.
In order to make this work, you need to export the ribbon definitions and identify where these controls are defined.
You should be able to define a CustomAction to override the definition of the existing control but include the label text you want to have instead of the default label text. See Define Custom Actions to Modify the Ribbon.
If you are already experienced with customizing the ribbon this shouldn't be too hard, but there is a signifcant learning curve when it comes to customizing the ribbon.

auto_complete_for: prevent the first item from being auto-selected

The auto_complete_for dealio from script.aculo.us is great an all, but is there a way for me to selectively disable the fact that it always auto-selects the first item in the list?
The problem is that, if I want to type my own entry that is new, and novel, I don't want the first item in the list to be auto-selected. The reason is because when I TAB out of the field, it selects, and fills the text box with that first item.
I got around that, somewhat, by making the first item in the list the same as what I'm typing, but that's not perfect either, because the auto_complete list doesn't always update with every keystroke, depending on how fast I type. I've tried setting the list refresh rate to the lowest value (1 millisecond) but no go.
What I really want is an option in "auto_complete_for" that doesn't select that first item at all - the same way that Google Instant doesn't automatically select the first suggested search phrase - you have to arrow-down to select one.
Maybe I can do this via an HTML option that I'm missing?
Looking at the source, there doesn't appear to be an option for that, but I bet if you changed line 284 of controls.js to this.index = -1; it would do what you want.
Otherwise, it might be time to look for a different autocomplete widget.
If your requirements are too far away from the available plugin, then I guess there is no point in tinkering around. Its best to write your own JS code.
You might want to consider this: https://github.com/laktek/jQuery-Smart-Auto-Complete
or this : https://github.com/reinh/jquery-autocomplete
I'll add another alternative that works great with Rails 3:
http://github.com/crowdint/rails3-jquery-autocomplete
I recently implemented auto complete for more than a field for Rails 2.0.2.
The plugin I used is:- https://github.com/david-kerins/auto_complete . Not sure if it supports Rails 3.
I have also encountered issues on implementing the above scenario and have posted questions( Implementing auto complete for more than one field in Rails ; Implementing a OnClick kind of functionality and formatting wrt Rails Partial-Views ) on stackoverflow for the same, I have been lucky on getting things working for me based on my requirement.
Kindly refer to these questions, they might have relevance to your requirement.

special character coming when i am using & and p

I dont know what exactly i have to type in title for this ,i tried my best
anyway coming to topic
I am making one acc checker for that purpose ,i am sending user and pass from my bsskinedit1 and bsskinedit2
here is my code
s:='http:\\site.com..premlogin='+bsskinedit.text+'&password='+bsskinedit2.text
but it giving some error ,then i used showmessage whats wrong with it then i came with strange result
see below
observer after 4 & and p combining together and appearing as a some new symbol :(
can any one tell me why its coming like this ?
Your code (where you build the URL) is most likely correct (I guess the above has some typos?!), but when you display the URL in a label for instance, the & character is treated as indicator for an accelerator key.
By Windows design, accelerator keys
enable the user to access a menu
command from the keyboard by pressing
Alt along the appropriate letter,
indicated in your code by the
preceding ampersand (&). The character
after the and sign (&) appears
underlined in the menu.
If you want to display the & character itself, you have to set your string variable to &&.
By placing two ampesands together - you state that the character following the first one is not used as the accelerator - rather you actually want to get it (only one) displayed.
Just use your debugger if you want to see the real value that your string variables have, don't output them to a message box or the like... It may have side effects, as you can see.
Regarding the URL you build: I can't possibly know how it has to be correctly, but at least you should use the right slashes!
s := 'http://site.com...'
(All quotes from delphi.about.com)
In addition to what Mef said, you can use OutputDebugString to add your string to the event log in its raw form, so you don't need to modify it before displaying it. Delphi should capture those strings automatically if you're running from the debugger. If you aren't running it from Delphi you can use DebugView instead, which captures the messages from any running applications.
