How can I change the syntax highlighting in vim for C/C++/PHP in particular?
Can I also change the background color so it won't be the same as the shell's?
Before you start installing various plugins, check out pre-installed color schemes that ships with your Vim. In my case I have many of them:
# rpm -ql vim vim-common | grep color
/usr/share/vim/vim72/colors
/usr/share/vim/vim72/colors/README.txt
/usr/share/vim/vim72/colors/blue.vim
/usr/share/vim/vim72/colors/darkblue.vim
/usr/share/vim/vim72/colors/default.vim
/usr/share/vim/vim72/colors/delek.vim
/usr/share/vim/vim72/colors/desert.vim
/usr/share/vim/vim72/colors/elflord.vim
/usr/share/vim/vim72/colors/evening.vim
/usr/share/vim/vim72/colors/koehler.vim
/usr/share/vim/vim72/colors/morning.vim
/usr/share/vim/vim72/colors/murphy.vim
/usr/share/vim/vim72/colors/pablo.vim
/usr/share/vim/vim72/colors/peachpuff.vim
/usr/share/vim/vim72/colors/ron.vim
/usr/share/vim/vim72/colors/shine.vim
/usr/share/vim/vim72/colors/slate.vim
/usr/share/vim/vim72/colors/torte.vim
/usr/share/vim/vim72/colors/zellner.vim
/usr/share/vim/vim72/ftplugin/dircolors.vim
/usr/share/vim/vim72/syntax/colortest.vim
/usr/share/vim/vim72/syntax/dircolors.vim
/usr/share/vim/vim72/syntax/syncolor.vim
/usr/share/vim/vimfiles/after/colors
/usr/share/vim/vimfiles/colors
To change it just use this:
colorscheme darkblue
Also you can download color schemes and just drop them into your VIMRC subdirectory "colors" and load them the same way. I like this one for example: http://ethanschoonover.com/solarized
And of course, you can modify those color schemes. Just copy the "default.vim" (or the one you like) to your VIMRC/colors and edit it to change colors you want.
You have to give it a syntax file to load and play around with it:
http://www.vim.org/scripts/script.php?script_id=1571
To enable it (in case you don't know) its :set syntax

I'm looking to customize the selection color in zsh history and found one example.
zstyle ':completion:*' list-colors 'ma=48;2;76;86;106'
It works, and I can tinker with the numbers to make changes, but I can't find an explanation for ma=.
What is ma=?
What is the format for ma=?
Is there another approach other than ma= to adjust the color?
ma= sets the color for the currently selected completion. See here for more info: https://zsh.sourceforge.io/Doc/Release/Zsh-Modules.html#Colored-completion-listings
Is there another approach other than ma= to adjust the color?
The link above explains how to adjust them by hand. However, this can be a rather tedious task, which is why I decided to write a Zsh plugin that does it for you: Z Colors takes the value of your $LS_COLORS and generates from it
completion colors,
syntax highlighting colors and
Git colors.
However, if you do want to go the manual route, have a look at its source code to see how I solved this problem. It’s completely free and open source.
How can I change the directories colors that appears as options for the autocomplete in zsh Powerlevel10k ?
As you can see in the image they don't really stand out very well with a dark background color.
I've tried to dig in the .oh-my-zsh/custom/themes/powerlevel10k/config but to no avail.
Thanks to Roman's answer, and after finding this post (so this question might be a duplicate) I have simply:
Created a ~/.dircolors (could be any path you'd like) file and copied the standard LS colors to it by doing
dircolors --print-database > ~/.dircolors
Found the line that deal with the directories' LS color and changed it (of course you can change to any color you'd like), i.e.
DIR 01;34
To this:
DIR 01;36
Sourced the new .dircolors file in my .zshrc by adding:
d=~/.dircolors
test -r $d && eval "$(dircolors $d)"
From their official docs, https://github.com/romkatv/powerlevel10k/blob/master/README.md#directory-is-difficult-to-see-in-prompt-when-using-rainbow-style.
for i in {0..255}; do print -Pn "%K{$i} %k%F{$i}${(l:3::0:)i}%f " ${${(M)$((i%6)):#3}:+$'\n'}; done
Execute this in your terminal to see the color code as well.
I am using Prezto + zsh as my shell. I would like to change the color of
directories when I ls my directory. For instance, here is what I currently
have:
Obviously, this is no fun, as I’m hardly able to read my directories because the
blue is so dark. I’d like to change it to white or orange or something lighter.
This dark blue is specific only to directories. Files show up in a nice white
text. Where and what settings must I find to change this?
Update
I've seen this answer still getting attention, so here's an update. Instead of messing with individual colours as below, simply adjust the Minimum Contrast within Preferences ... -> Profiles -> Colors. I set mine to 60.
Original answer
The easier way to do this is to change the colour scheme of your terminal. For example if you are using iTerm2 on a Mac then:
Launch iTerm2
type CMD+i
In the "Colors" tab, change the setting for "Blue" (and potentially the "Bright" equivalient)
In the "General" tab, click "Copy Current Settings to Selected Profile"
If you want to revert back to the defaults you can always select a value from the "Color presets..." dropdown in the "Colors" tab.
Do the equivalent in your favourite terminal if you don't use iTerm2 on a Mac.
The answer depends on your ls. BSD ls uses the environment variable LSCOLORS; coreutils ls uses LS_COLORS instead. See your man page.
The utility module of Prezto uses dircolors (if available) to customize the colors of coreutils ls, which also comes with coreutils. So if you have coreutils, then you can use dircolors to provide actually human-readable color definitions. Read the man page of dircolors for details. Prezto reads from $HOME/.dir_colors by default, otherwise it just use the default colors defined by dircolors. You can of course specify other locations by editing on top of Prezto.
For BSD ls, there's probably no utility comparable to dircolors, so one has to manually define LSCOLORS. See the ENVIRONMENT section of the man page on its format, which should be pretty clear. An example is LSCOLORS='exfxcxdxbxGxDxabagacad', used by Prezto by default. To have it take effect, put it in runcoms, after loading Prezto's utility module.
I may be late to the party but I found the answer here: https://github.com/sorin-ionescu/prezto/issues/1539
Run in the Terminal or add to your .zshrc file
export LSCOLORS="ExGxBxDxCxEgEdxbxgxcxd"
OK, so I'm using this little fancy cutting edge technology called zsh-syntax-highlighting and although I'm overall happy with the result I don't know how to set styles to anything but 8 basic colors (black, red, green, yellow, blue, magenta, cyan, white), e.g.
#works
ZSH_HIGHLIGHT_STYLES[path]='fg=red'
ZSH_HIGHLIGHT_STYLES[path]='fg=1'
#doesn't work
ZSH_HIGHLIGHT_STYLES[path]='fg=31m'
ZSH_HIGHLIGHT_STYLES[path]='fg=\e[31m'
ZSH_HIGHLIGHT_STYLES[path]='fg=%{\e[31m%}'
ZSH_HIGHLIGHT_STYLES[path]='31m'
ZSH_HIGHLIGHT_STYLES[path]='\e[31m'
ZSH_HIGHLIGHT_STYLES[path]='%{\e[31m%}'
ZSH_HIGHLIGHT_STYLES[path]='%{\e[1;38;5;118m%}'
So, how do I set more fancy colors for this zshzle plugin?
As you pointed out in the comment to chepner answer terminator is a fork of gnome-terminal and it still uses a lot of functions from gnome. In fact it seems that the whole terminator VTE widget comes from gnome and gnome-terminal by defaults "supports" only 8 basic colors. You can check that with echotc Co command. It will return 8 for both of them and for xterm too (although in xterm case this is true and only 8 colors), so basically all 3 terminal emulators you tried so far.
Now, you noted that teminator (and gnome-terminal) can in fact display more colors, but this is only because it more or less processes all those special color codes without paying attention to TERM settings what does not obey standards but well, this is gnome. Anyway to make long story short you need to set TERM environment variable to something like xterm-256color and check again with echotc Co - you should now see 256, and your ZSH_HIGHLIGHT_STYLES[path]='fg=217' should work as well.
To always start with 256 colors you can put into you .zshrc
[[ "$TERM" == "xterm" ]] && export TERM=xterm-256color
and if you have any gnome shortcuts with terminator then change them as follows
terminator -e "TERM=xterm-256color pine"
http://zsh.sourceforge.net/Doc/Release/Zsh-Line-Editor.html#Character-Highlighting suggests that the value for fg be a single integer from 0 to 255:
ZSH_HIGHLIGHT_STYLES[path]='fg=167' # Whatever color 167 is in the 256-color palette.
I Notice you are using [path], it could be that a custom path with it's own color setting is interfering with your highlight setting. Try testing with a different item such as [command]:
ZSH_HIGHLIGHT_STYLES[command]='fg=222'
I tried the above line and it works for me. I tried using the same value for path already knowing my custom prompt has its own colors and my prompts custom colors won out over the highlight.
I use a ZSH helper called Oh-My-ZSH so the following may be a bit different or not apply to you:
Make sure you are changing the color definition after the highlight plugin is loaded. On my setup it will actually generate an error but since I only tested on my syetem (OSX10,9, ZSH 5.0.7, Oh-My-ZSH, iTerm v2) your experience may be different.
Doesn't work:
ZSH_HIGHLIGHT_STYLES[command]='fg=222'
...
plugins=(git osx jim colorize zsh-syntax-highlighting)
Does work:
plugins=(git osx jim colorize zsh-syntax-highlighting)
...
ZSH_HIGHLIGHT_STYLES[command]='fg=222'
By default PHPUnit does not use colour output. One can add the --colors flag to the phpunit command or add colors="true" to the config file.
I'd like to have colors by default and hence have the setting in my config file. This is nice since I can then run phpunit rather than phpunit --colors most of the time. However I do have one place where the terminal does not support color output. When colors are enabled there, it makes the output less readable.
Is it possible to keep colors on by default and disable it for this specific terminal? There appears to be no --no-colors flag or similar. And ideally I'd not have to specify this anywhere to begin with, and be able to specify something like colors="auto", which then detects if the terminal supports ANSI colors or not.
If you are working under a unix like terminal you could add the following to your .bash_profile
alias phpunitc='phpunit --colors'
In this way you could have colors calling phpunitc, and no colors calling phpunit (this would require that you remove the colors="true" setting from the configuration file).
