Probably you just need to tell vim that you have a dark background:

    :set background=dark

This should change the highlighting to something better readable.

Take a look at `syncolor.vim`. You&#39;ll find it in `/usr/share/vim/vim{version}/syntax/`.

Excerpt:

    &quot; There are two sets of defaults: for a dark and a light background.
    if &amp;background == &quot;dark&quot;
      SynColor Comment	term=bold cterm=NONE ctermfg=Cyan ctermbg=NONE gui=NONE guifg=#80a0ff guibg=NONE
      SynColor Constant	term=underline cterm=NONE ctermfg=Magenta ctermbg=NONE gui=NONE guifg=#ffa0a0 guibg=NONE
      SynColor Special	term=bold cterm=NONE ctermfg=LightRed ctermbg=NONE gui=NONE guifg=Orange guibg=NONE

So the first `SynColor` line looks of interest. I confess I don&#39;t know if you can override this, as opposed to changing this file.

If you want to change the color of a comment without changing the background, you can use the `highlight` command. [Vim documentation on :highlight](http://vimdoc.sourceforge.net/htmldoc/syntax.html#:highlight)

For example, `:hi Comment term=bold ctermfg=Cyan guifg=#80a0ff gui=bold
`

[$VIMRUNTIME/colors/README.txt][1] (on my system, /usr/share/vim/vim72/colors)


  [1]: http://www.linuxquestions.org/questions/programming-9/vim-syntax-highlighting-625734/

You can set `colorsheme` to `desert`. Default in e.g. Ubuntu 16.04

best way is to change colorscheme to another (lighter) one:

in navigation mode type:

:colorscheme &lt;kbd&gt;space&lt;/kbd&gt; &lt;kbd&gt;Ctl&lt;/kbd&gt;+&lt;kbd&gt;D&lt;/kbd&gt;

and then type the scheme name &lt;kbd&gt;Enter&lt;/kbd&gt;



What should be used and when? Or is it always better to use UTF-8? Or [ISO-8859-1][1] still has importance in specific conditions?

Is the haracter set related to geographic region?

----------

Is there a benefit to using the code `@charset &quot;utf-8&quot;;`?

Or like this `&lt;link type=&quot;text/css; charset=utf-8&quot; rel=&quot;stylesheet&quot; href=&quot;..&quot; /&gt;`

at the top of the CSS file?

I found for this

&gt; If [Dreamweaver][2] adds the tag when you
&gt; add embedded style to the document,
&gt; that is a bug in Dreamweaver. From the
&gt; W3C FAQ:
&gt;
&gt; &quot;For style declarations embedded in a
&gt; document, @charset rules are not
&gt; needed and must not be used.&quot;
&gt;
&gt; The charset specification is a part of
&gt; CSS since version 2.0 (may 1998), so
&gt; if you have a charset specification in
&gt; a CSS file and Safari can&#39;t handle it,
&gt; that&#39;s a bug in Safari.

And add **accept-charset** in the form:

    &lt;form action=&quot;/action&quot; method=&quot;post&quot; accept-charset=&quot;utf-8&quot;&gt;

And what should be used if I use the XHTML doctype?

    &lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?&gt;

or

    &lt;meta http-equiv=&quot;Content-Type&quot; content=&quot;text/html; charset=UTF-8&quot; /&gt;

I have to send out massEmails to all users of a website. I want to use a thread pool for each email that is sent out. Currently I have set the values to :

    &lt;property name=&quot;corePoolSize&quot; value=&quot;500&quot; /&gt;
    &lt;property name=&quot;maxPoolSize&quot; value=&quot;1000&quot; /&gt;

What is the difference between the two and will it scale. Currently I have approx. 10000 users.

I write a lot of shell scripts and I am constantly having to enter in filepaths. I am wondering if anyone knows of a way to get Vim to autocomplete filepaths while in insert mode, just like when you are in your favorite shell you tab to complete the path of the directory or file. 

Extra credit if you can get &lt;kbd&gt;CTRL&lt;/kbd&gt;&lt;kbd&gt;D&lt;/kbd&gt; functionality of the shell into Vim insert mode (i.e. to see what files/directories are in the current path).

When in Vim insert mode, is there a way to add filepath autocompletion?

I would like to delete every other line from a Vim buffer, starting with the second one, i.e., lines&#160;2,&#160;4,&#160;6, etc. For example, if the buffer’s contents is:

    aaa
    bbb
    ccc
    ddd
    eee
    fff

then, after the desired line removal, it should become:

    aaa
    ccc
    eee

Which Vim commands can be used to automate this operation?

I was trying to switch from a tab to another tab (which may not be adjacent to the previous tab) in VIM. Is there any shortcut for that, like we have &lt;kbd&gt;Ctrl&lt;/kbd&gt;-&lt;kbd&gt;p&lt;/kbd&gt;/&lt;kbd&gt;Ctrl&lt;/kbd&gt;-&lt;kbd&gt;n&lt;/kbd&gt; for switching to adjacent tabs? 

Also, I was trying to write a key mapping which will give a variable as input to a function and do the operation. For instance, let&#39;s say I press &lt;kbd&gt;Ctrl&lt;/kbd&gt;-&lt;kbd&gt;5&lt;/kbd&gt; and a function (written by the user) will be called and given as input 5, and the cursor will go to tab 5 (if there is any 5th tab opened).

Can you please suggest how this can be done?

I want to create a `System.Drawing.Color` from a value like `#FF00FF` or `FF00FF` without needing to write code for that. There is any .NET built-in parser for that?

How to create a System.Drawing.Color from its hexadecimal RGB string?

I&#39;m trying to color parts of a string to be appended to a RichTextBox. I have a string built from different strings.

    string temp = &quot;[&quot; + DateTime.Now.ToShortTimeString() + &quot;] &quot; +
                  userid + &quot; &quot; + message + Environment.NewLine;

This is what the message would look like once it is constructed.

&gt; [9:23pm] User: my message here.

I want everything within and including the brackets [9:23] to be one color, &#39;user&#39; to be another color and the message to be another color. Then I&#39;d like the string appended to my RichTextBox.

How can I accomplish this?

Color different parts of a RichTextBox string

I have the following HTML:

    &lt;div class=&quot;menu&quot;&gt;
        &lt;a class=&quot;main-nav-item&quot; href=&quot;home&quot;&gt;home&lt;/a&gt;
        &lt;a class=&quot;main-nav-item-current&quot; href=&quot;business&quot;&gt;business&lt;/a&gt;
        &lt;a class=&quot;main-nav-item&quot; href=&quot;about-me&quot;&gt;about me&lt;/a&gt;
    &lt;/div&gt;

In CSS, I want to set the `a:hover` for these menu items to a particular color. So I write:

    .menu a:hover
    {
        color:#DDD;
    }

But, I want to set this `a:hover` color only for those `&lt;a&gt;` tags with the class *main-nav-item* and not the *main-nav-item-current*, because it has a different color and shouldn&#39;t change on hover. All `&lt;a&gt;` tags within the *menu* div should change color on hover except the one with the *current* class.

How can I do it using CSS?

I tried something like

    .menu a:hover .main-nav-item
    {
        color:#DDD;
    }

thinking that only ones with main-nav-item class will change color on hover, and not the current one. But it is not working.

I am looking for an &quot;**eyedropper**&quot; tool, that gives me the hex value of the pixel the mouse cursor is under, in JavaScript for a CMS.

For Firefox, there is the excellent [**ColorZilla**][2] extension that does exactly that. However, it&#39;s FF only of course, and I would really like to deliver the tool along with the CMS.

A dutch developer has had the [**very clever idea**][1] of using a combination of Ajax and PHP&#39;s `imagecolorat()` to find out the Pixel colour on an image. **But that limits the range to images I can access server side**, and I&#39;m really dreaming of a universal tool. 

I will work with one of these approaches, but would much prefer a cross-browser, Javascript or Flash based way that requires no server-side fiddling and no installing of extensions.

I am also interested in any IE specific solutions that do what ColorZilla can do - I could live with supporting IE and FF only, though a cross browser solution would of course be ideal.

Is there a way to change the color of an axis (not the ticks) in matplotlib? I have been looking through the docs for Axes, Axis, and Artist, but no luck; the matplotlib gallery also has no hint.
Any idea?

I need to highlight source code in LaTeX. The package `listings` seems to be the best choice for most use-cases and for me it was, until now.

However, now I need more flexibility. Generally, what I’m looking for is a *real* lexer. In particular, I need (for an own language definition) to define (and highlight!) own number styles. `listings` does not allow highlighting numbers in code. However, I need to produce something like this:

![Required result][]

`listings` also cannot cope with arbitrary delimiters for strings. Consider the following valid Ruby code:

    s = %q!this is a string.!

Here, `!` can be replaced by almost *any* delimiter.

(That `listings` cannot handle Unicode is also quite vexing, but that’s another issue.)

**Ideally, I am looking for an extension of `listings` that allows me to provide more complex lexing rules. But barring that, I am also searching for viable alternatives.**

[Other threads](https://stackoverflow.com/questions/300521/latex-package-to-do-syntax-highlighting-of-code-in-various-languages/1452086#1452086) have suggested using [Pygments](http://pygments.org/) which can produce LaTeX output. There’s even a package – [`texments`](http://www.ctan.org/tex-archive/macros/latex/contrib/texments/) – to ease the transition.

However, this sorely lacks features. In particular, I am interested in `listings`-style line numbering, source code line references, and the possibility of embedding LaTeX in source code (options `texcl` and `mathescape` in `listings`).

As an example, here’s a source code typeset with `listings` which shows some of the things that a replacement should also provide:

&lt;sup&gt;&lt;sub&gt;[“Sideways addition” modified from Bit Twiddling Hacks]&lt;/sub&gt;&lt;/sup&gt;

I find that in various situations Objective-C code in Xcode 3.1 (Leopard) can fail to get appropriate syntax coloring after typing or lose coloring that it had.

This isn&#39;t just a &quot;refresh&quot; issue with new custom symbols -- but affects Cocoa framework symbols as well.

Sometimes CMD-a to select all text on the code page will make the coloring (re)appear, sometimes double-clicking on a line to select it will work, sometimes I have to add/delete a space in a symbol to get that symbol to (re)color. Rebuilding, or closing/reopening the project may or may not work.

Is this a known issue with Xcode? For something so annoying to me, I&#39;m not finding the plentiful discussions of it on SO and elsewhere I&#39;d expect.

And is there any command to force global syntax recoloring?

I would like rainbow parens for editing Clojure in Emacs and since [VI does this][1] I assume that in Emacs it should be something like M-x butterfly or something :)

How do I get &quot;rainbow parentheses&quot; in emacs?

You can *set* the Vim color scheme by issuing

    :colorscheme SCHEME_NAME

but, oddly enough, you can&#39;t get the currently used scheme by issuing

    :colorscheme

as this results in &quot;`E471: Argument required`&quot;. I also don&#39;t see the color scheme listed in the output of `:set`.

So how do you go about figuring out the current color scheme in use (other than manually switching the themes until you recognize it)?
