Wanna clean dock on your Mac 🍎? Add spacers between irrelevant apps and clear the clutter!

Hasan Nadeem — Wed, 27 Jul 2022 21:09:05 +0000

You can add spacers(either small or default sized blank icon) between apps on your dock and put relevant apps together for quicker access. 💭

Hit the following command on your favorite terminal and VOILA! 🎉🎉🎉

defaults write com.apple.dock persistent-apps -array-add '{"tile-type"="small-spacer-tile";}'; killall Dock

the killall Dock will kinda restart your dock and add small sized spacers on the most right side. You can drag those spacers wherever you want to on your dock.

Instead of small-spacer-tile you can try spacer-tile in the aforementioned command and the default sized spacer will appear on the dock.

You can remove the spacers pretty easily. Check the following screenshot.

Ruby/Rails Machine Setup Guide

1- IDE

We prefer to use sublime/VS Code for development(you can opt for any IDE though, but that will mean no support from seniors for any issues relating it and that might lead to un-neccessary time waste thats why it is highly preferred to not use any other IDEs). You are encouraged to use sublime or VSCode.

Sublime:

Install Sublime3 (google or use this link)
Here we will outline some basic configuration for sublime3 we usually use.

i- Settings Tweaks
In sublime go to preferences->settings and place these in user settings tab along with other settings.
Don't mess with default settings tab

{
  "auto_complete_commit_on_tab": true,
    "auto_complete_triggers":
    [
        {
            "characters": "b4",
            "selector": "text.html"
        }
    ],
    "auto_indent": true,
    "caret_style": "phase",
    "color_scheme": "Packages/Color Scheme - Default/Monokai.sublime-color-scheme",
    "draw_minimap_border": true,
    "draw_white_space": "all",
    "enable_tab_scrolling": false,
    "ensure_newline_at_eof_on_save": true,
    "file_exclude_patterns":
    [
        "*.pyc",
        "*.pyo",
        "*.exe",
        "*.dll",
        "*.obj",
        "*.o",
        "*.a",
        "*.lib",
        "*.so",
        "*.dylib",
        "*.ncb",
        "*.sdf",
        "*.suo",
        "*.pdb",
        "*.idb",
        "*.class",
        "*.psd",
        "*.db",
        "*.beam",
        ".DS_Store",
        ".tags"
    ],
    "folder_exclude_patterns":
    [
        ".svn",
        ".git",
        ".hg",
        "CVS",
        ".sass-cache"
    ],
    "font_options":
    [
        "gray_antialias"
    ],
    "font_size": 15,
    "gutter": true,
    "highlight_line": true,
    "highlight_modified_tabs": true,

        "SublimeLinter-contrib-eslint_d",
        "SublimeLinter-eslint",
        "Vintage"
    ],
    "line_numbers": true,
    "line_padding_top": 0,
    "mouse_wheel_switches_tabs": false,
    "overlay_scroll_bars": "enabled",
    "preview_on_click": true,
    "rulers":
    [
        120
    ],
    "scroll_past_end": false,
    "show_tab_close_buttons": false,
    "tab_size": 2,
    "theme": "Adaptive.sublime-theme",
    "translate_tabs_to_spaces": true,
    "trim_automatic_white_space": true,
    "trim_trailing_white_space_on_save": true,
    "use_tab_stops": true,
    "wide_caret": true,
    "word_separators": "./\\()\"'-:,.;<>@#$%^&*|+=[]{}`",
    "indent_using_spaces": true,
    "index_files": true,
    "line_padding_bottom": 2,
    "line_padding_top": 0,
    "rulers":
    [
        90,
        100,
        120
    ],
    "show_sidebar_on_save": false,
    "spell_check": true,
    "tab_width": 2,
    "word_wrap": false
}

Have an eye for any redundency in settings and replace that if there is any.

This will make indentation more easy, as indentation is one of the most important things for code quality and useability.

ii- Sublime Package Control
Install package control following:
This link

After that, you can access package control in preferences and install any package you need(Like gitgutter, A file icon, beautifyruby, brackethighlighter etc).

Here is the list of some handy packages in sublime, you can install them in some spare time. Not required but helpful for development.
iii- Useful Sublime Packages:

A File Icon
All Autocomplete
Better CoffeeScript

VSCode:

Download and install VSCode from here

Recommended settings for VSCode:

    "ruby.useLanguageServer": true,
    "ruby.format": "rubocop",
    "ruby.intellisense": "rubyLocate",
    "ruby.useBundler": true,
    "ruby.rubocop.useBundler": true,
    "[ruby]": {
        "editor.defaultFormatter": "misogi.ruby-rubocop"
    },
    "editor.tabSize": 2,
    "files.insertFinalNewline": true,
    "telemetry.enableTelemetry": false,
    "window.titleBarStyle": "custom",
    "files.trimTrailingWhitespace": true,

Add these settings in File > Preferences > Settings (open the settings in json)

Following are some recommended extension for VScode. Please run the following commands on terminal for installing the extensions:

code --install-extension castwide.solargraph
code --install-extension dbaeumer.vscode-eslint
code --install-extension donjayamanne.githistory
code --install-extension eamodio.gitlens
code --install-extension HookyQR.beautify
code --install-extension IBM.output-colorizer
code --install-extension mhutchie.git-graph
code --install-extension misogi.ruby-rubocop
code --install-extension rebornix.ruby
code --install-extension wheredoesyourmindgo.gruvbox-concoctis
code --install-extension wingrunr21.vscode-ruby

You can install these through command line, one by one using the command: code --install-extension $EXT_NAME.

2- Ruby environment/version manager with Rails Setup

Link for Ruby/Rails/Rbenv/Postgres Setup
Note: Please do the following while going through the above article.

Please install and use RBENV. Skip RVM
Please install Ruby version 2.6+ / Rails version 6 / Postgres version 11
Please set the Postgres username to postgres with password postgres - MUST
Please skip Configuring Git

3- Database

It is preferred to use postgresql dbms for development, as it is a de-facto standard in most rails applications. Books may be using sqlite 3 but it is encouraged to use postgresql.

TIP: If you keep an eye on what these commands actually are doing, that will be beneficial for you. Like you can give 2-4 mins on reading about apt-get and what it actually does, give 2 minutes to read about sudo or any new command like curl if you don't know about it, this will help you grip ubuntu/linux quickly.

Terminal

For Fancy/Pretty Diff -> https://github.com/so-fancy/diff-so-fancy
For common git aliases, run the following commands on terminal:

git config --global alias.co checkout
git config --global alias.br branch
git config --global alias.ci commit
git config --global alias.st status

rbenv: bundle: command not found

Hasan Nadeem — Wed, 13 Jan 2021 19:49:03 +0000

For those using RBENV for managing ruby versions, whenever you install a different ruby version and then you'll be faced with the following error(not 100% same lol):

rbenv: bundle: command not found

The `bundle' command exists in these Ruby versions:
  2.3.3
  2.4.4
  2.5.7
  2.6.5
  2.7.0

Both these commands will be helpful in fixing the issue.

gem update --system

bundle update --bundler

Running Rails Console Commands on Terminal

Hasan Nadeem — Fri, 08 Jan 2021 12:32:13 +0000

Wherever you are unable to run the rails console directly we can use something else. I found that to be helpful since I didn't have admin rights on the EC2 terminal but I had to play with rails console for Staging Environment

bundle exec rails runner "_rails command_" -e $(ENVIRONMENT)

is that helpful command which helped me in running rails commands for the staging environment. We should definitely avoid using it as much as possible but there are scenarios where playing with rails console is our only choice.

Example commands:

bundle exec rails runner "puts Cart.where(tenant_id: 3).destroy_all" -e staging
