ZSH Sorting Associative Arrays

As I dive into ZSH more and more and start to put more hours into zshbop, I’m finding it harder to locate good ZSH documentation. I got stuck with an associative array being unsorted, why? I started to document all of the scripts and commands I’ve created and used the following format.

help_files[gcp]='GIT commit then push!'

This makes it super easy to explain all of the scripts and functions I have without having to place them all in one help file. I just use the associative array just above the function I’m writing.

The problem is that they’re unordered as I create them as needed. This results in the help file spewing the following out.

-- Help Command Categories --

  help php                       - PHP related commands
  help wordpress                 - WordPress related commands
  help ssh                       - SSH related commands
  help nginx                     - Nginx related commands
  help software                  - Software related commands
  help software_description      - -- To install, run software <cmd>
  help ubuntu                    - Ubuntu OS related commands
  help mail                      - All mail related commands
  help git                       - Git related commands
  help mysql                     - MySQL related commands
  help linux                     - Linux related commands
  help core                      - Core commands

It’s super ugly. So I started to look at trying to sort the associate array somehow. I first thought I could actually sort the array data, take out the data and then put it back in. But I thought that was too much work, and I wouldn’t understand the code as it was a copy and paste snippet I found on Stack Overflow.

I started to use ZSH substitution modifiers, which I had already been using for creating my command categories and other help verbiage. Here’s an example of listing all of the category commands.

help_files[nginx]='Nginx related commands'
help_files[php]='PHP related commands'
help_files[mail]='All mail related commands'
help_files[ubuntu]='Ubuntu OS related commands'

for key value in ${(kv)help_files}; do
        printf '%s\n' "  help ${(r:25:)key} - $value"

This works out well and the output is what you see in the previous code snippet. It’s just not sorted.

So I tried to work with ZSH substitutions but I couldn’t figure out how to return a key and values while also sorting. I couldn’t use (okv) this broke and I don’t know why. Still learning….

So instead I just grabbed the key, and sorted it. Then passed the kay to the array to print out the value. So easy.

        for key in ${(kon)help_zshbop}; do
                printf '%s\n' "  zshbop ${(r:25:)key} - help_zshbop[$key]"

Windows 10, ZSH, Putty, Powerline Fonts and Screen

I recently was setting up my Windows 10 desktop machine with Putty so I could access some servers. I use the ZSH shell with OMZ and the Powerline9k theme. I use the following article to set up Putty and grab the appropriate fonts for Windows 10 that were patched.


There were some additional options on the following blog article that were required.

Oh My ZSH! with PuTTY

Everything was working great until I was having issues with powerline font’s not showing correctly when using screen.

Running the powerline echo test below resulted in hashed blocks.

echo “\ue0b0 \u00b1 \ue0a0 \u27a6 \u2718 \u26a1 \u2699”

echo "\ue0b0 \u00b1 \ue0a0 \u27a6 \u2718 \u26a1 \u2699"

Turns out I didn’t have my locale set in my shell environment.

export LANG=”C.UTF-8″

export LANG="C.UTF-8"

Once I had the appropriate locale set, everything worked fine.
