Customizing Powerleve10k prompt - zsh

I just added the Powerlevel10k theme to my zsh and i'm trying to configure certain parts.
It currently looks like this:
The ~/.p10k.zsh has a lot of configurations done and I've been trying to change certain things but i'm not there yet.
I don't want to print the whole path on the left prompt, just the directory. Also, not sure what those numbers indicate in the git section. And the right prompt is displaying my ruby version, although I haven't used Ruby in ages and want to change it to a different setting.
I've tried adding a PS1=... to .zshrc but it seems to be overriden by the P10K config file.
Any suggestions?

Display only the last directory segment
Open ~/.p10k.zsh.
Search for POWERLEVEL9K_SHORTEN_STRATEGY.
Change the value of this parameter to truncate_to_last.
Alternatively, change the value of POWERLEVEL9K_DIR_MAX_LENGTH to 1. This will maximally shorten current directory while keeping the transformation reversible. You can restore the original directory by copy-pasting the shortened directory to the command line and pressing TAB.
Ruby version
Powerlevel10k has several prompt segments that can display Ruby version. By default only those are enabled that display Ruby version when it has been manually overridden by some tool (e.g., rbenv or asdf).
To remove Ruby version from prompt:
Open ~/.p10k.zsh.
Search for POWERLEVEL9K_RIGHT_PROMPT_SEGMENTS.
Remove or comment out the following elements: rbenv, rvm and asdf.
Alternatively (and perhaps preferably), find out which tool is overriding Ruby version for you and remove the override if you no longer need it.

shorten dir segment to show only deepest directory
To show only last n significant path segments, you can set following in your config .zshrc, e.g n=1 means show only last folder in present working directory:
POWERLEVEL9K_SHORTEN_DIR_LENGTH=1
See https://stackoverflow.com/a/49027654
explain Git symbols
The question/exclamation mark in Git segment (vcs segment, next to path) means the number of files untracked (?) and unstaged (!). For detailed description see What do different symbols in Git status mean?
change version segment
You can change the version segment (on the right of prompt) to reflect another tool. For example to replace shown ruby version by python version replace the element within right promt elements in your config .zshrc:
POWERLEVEL9K_RIGHT_PROMPT_ELEMENTS=(rbenv)
by
POWERLEVEL9K_RIGHT_PROMPT_ELEMENTS=(pyenv)

ZSH - print java version in right prompt

I have a daily use case where I need to work with projects on different version of Java (8, 11, ...).
I would like to have it displayed in the right side prompt in my shell (ZSH with Oh-My-Zsh). I know of a dummy way (computationally expensive) to do it (just java --version to var and display it). I would like it to have it cached until I don't source a file (which is a specific project file that sets the new env vars for different java versions).
Do you have any ideas how to do this efficiently?
Br,
Stjepan
The PROMPT and RPROMPT variables can have both static and dynamic parts, so you can set the version there when you source the project file, and it will only be calculated one time. The trick is to get the quoting right.
This line goes in the project file that sets the env variables, somewhere after setting PATH to include the preferred java executable:
RPROMPT="${${=$(java --version)}[1,3]}"
The pieces:
RPROMPT= - variable for the right-side prompt.
"..." - the critical part. Variables in double quotes will be expanded then and there, so the commands within this will only be executed when the project file is sourced.
${...[1,3]} - selects the first three words of the enclosed expression. On my system, java --version returns three lines of data, which is way too big for a prompt; this reduces it to something manageable.
${=...} - splits the enclosed value into words.
$(java --version) - jre version info.

Why plugin z of zsh is not active inside the .zshrc?

I installed oh my zsh and zsh auto suggestion. Then I read here (https://www.sitepoint.com/zsh-tips-tricks/) about z zsh, an interesting plugin. And I really wanted to install it. So I put the plugin inside my .zshrc file. But the plugin feature is not active, it's not yellow like source command or alias (and those are properly working). I tried to change place of the plugin line (after / before source), but it didn't work. I did'nt understand the first line. My .zshrc, if someone could help...:
export PATH=$HOME/bin:/usr/local/bin:$PATH
export ZSH="/home/yanalolux/.oh-my-zsh"
ZSH_THEME="ys"
. /home/yanalolux/z.sh
source $ZSH/oh-my-zsh.sh
plugins=(z zsh-autosuggestions)
plugins=(zsh-autosuggestions)
In your .zshrc you have the following two lines:
plugins=(z zsh-autosuggestions)
plugins=(zsh-autosuggestions)
The second line remove the z plugin. You should have only one line with:
plugins=(z zsh-autosuggestions)
According to the ZSH-z plugin Github homepage:
ZSH-z is a command line tool that allows you to jump quickly to directories that you have visited frequently in the past, or recently -- but most often a combination of the two (a concept known as "frecency"). It works by keeping track of when you go to directories and how much time you spend in them. It is then in the position to guess where you want to go when you type a partial string, e.g. z src might take you to ~/src/zsh.

GNAT Metric and RTL files

For running GNAT metric (for Windows, GPL 2017 or CE 2018) I'd like to include the RTL sources as well. There is a "-a" switch but it seems to be ineffective. When I'm forcing visibility of RTL sources, only ada.ads and system.ads are processed. Guessing it is a "crunched name" issue (RTL file names forced to 8 character names) I've tried other tricks without success.
My question is: is there a way to get the RTL source metrics (of the source files actually used) with GNAT Metric?
I'm using the command
gnatmetric -a -xs -nt -j0 -Pmyproj.gpr -U somemain.adb
TIA
In the meantime I've found a workaround by using the gnathtml.pl script.
I've customized the script a bit by removing the H1 headers.
The result is a few hundreds of HTML files with the sources of units actually used: the script does find all dependencies, recursively, through the .ali files - including the RTL.
Then I group the HTML files together, convert them back to text files, pass them through Adalog's Normalize tool for removing comments and empty lines, count lines with the wc command, and the job is done.

How to change to the next above directory

I really would like to know how to change directory to the next file, using 2 dots (/..).
I can go back to previous directory but how to do something like that to go to the next directory WITHOUT THE NAME OF THE FILE PLEASE!
I know it is possbile with the name of the folder but my answer is different, please let me know.
What O.S are you using? In linux ubuntu/Debian distributions (and probably in windows, not sure), you can enter the first child directory by simply typingcd */, this will change your current directory to the first child directory available in alphabetical order, example:
-/home
-alan
-desktop
-music
-alex
-documents
-pictures
-lisa
Assuming your in /home, if you write cd */ in the terminal you will be in /home/alan, because -alan is the first folder/directory available.

Changing directory color with zsh + Prezto

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"
