Install Ruby

Ruby Version Manager

brew install rbenv ruby-build

# Add rbenv to bash/zsh (.bash_profile/.zshrc) so that it loads every time you open a terminal
echo 'if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi' >> ~/.bash_profile
source ~/.bash_profile

echo 'if which rbenv > /dev/null; then eval "$(rbenv init - zsh)"; fi' >> ~/.zshrc
source ~/.zshrc

# If you're using Zsh
echo 'export PATH="$HOME/.gem/ruby/2.7.2/bin:$PATH"' >> ~/.zshrc
echo 'export PATH="/usr/local/opt/ruby/bin:$PATH"' >> ~/.zshrc

# If you're using Bash
echo 'export PATH="$HOME/.gem/ruby/2.7.2/bin:$PATH"' >> ~/.bash_profile

# Install Ruby
rbenv install 2.7.2
rbenv global 2.7.2
ruby -v

rbenv rehash

# to check outdated gems
gem outdated

#update all outdated gems
sudo gem update

# delete older gems
sudo gem cleanup

The first thing you want to do after installing a new Ruby version is to install Bundler.
This tool will allow you to set up separate environments for your different Ruby projects, so their required gem versions won't conflict with each other.
Install Bundler with:

gem install bundler

In a new Ruby project directory, create a new Gemfile with: like venv of python environment
bundle init

Make ls, ll commands colorful

exa
```
brew install exa
```

LSD --> I liked this one

brew install lsd
alias ll='lsd -la'
alias ls='lsd'

colorls --> slower compared to other plugins
```
$sudo gem install colorls
```

Snapshots of my configurations:

+ — uncommitted changes in the index;

Smart cd command

zoxide

fzf

brew install zoxide
brew install fzf
# add following at the end of zshrc file
eval "$(zoxide init --cmd cd zsh)"

powerlevel10k configuration

To configure powerlevel10k, execute following command and choose suitable options for you

p10k configure

This will generate following files and you can have multiple files for each of the config

mv ~/.p10k.zsh ~/.p10k.zsh.config1

To use desired config

cp ~/.p10k.zsh.config1 ~/.p10k.zsh

Restart the terminal.

Other customizations you can try:

⬆️

iterm2 color theme

The color scheme I have used in above iterm2 snapshots is here

If you need different color schemes then you can ref

Download the colorscheme file
double click on it, iterm2 will import it.

Terminal File Manager

Installation:

brew install nnn

OR
Refer installation instructions from here
OR
This will add icons to directories and files
Note: Nerd fonts should be installed and configured.

wget https://github.com/jarun/nnn/archive/refs/heads/master.zip
tar -zxvf master.zip
cd nnn-master/
# Not Zero, but Alphabet O, you will get binary nnn in same folder and you can move this bonary to the place you want and use it.
sudo make O_NERD=1

# Since I have install nnn with homebrew and it does not give any colors and icons, so  compiled it manually and replaced nnn binary file
sudo cp nnn /usr/local/Cellar/nnn/4.0/bin/
alias nnn='nnn -de'

Plugins

curl -Ls https://raw.githubusercontent.com/jarun/nnn/master/plugins/getplugs | sh

Plugins are installed to ${XDG_CONFIG_HOME:-$HOME/.config}/nnn/plugins.

Add active plugin list to .zshrc/.bashrc file

export NNN_PLUG='f:finder;o:fzopen;p:mocplay;d:diffs;t:nmount;v:imgview'

Uniform commit message format

commitizen

In case if you want to change message prompt and add additional types then edit following file

Add following code at the end of files /usr/local/lib/python3.11/site-packages/commitizen/defaults.py and /usr/local/Cellar/commitizen/3.5.4/libexec/lib/python3.11/site-packages/commitizen/defaults.py.

version_parser = r"(?P<version>([0-9]+)\.([0-9]+)\.([0-9]+)(?:-([0-9A-Za-z-]+(?:\.[0-9A-Za-z-]+)*))?(?:\+[0-9A-Za-z-]+)?(\w+)?)"

For "conventional_commits" type template
commitizen-version --> replace version number
File: /usr/local/lib/python3.11/site-packages/commitizen/cz/conventional_commits/conventional_commits.py, /usr/local/Cellar/commitizen//libexec/lib/python3.11/site-packages/commitizen/cz/conventional_commits/conventional_commits.py

This has one downside that, for every commitizen upgrade, need to change ^^ files manually

cp /usr/local/lib/python3.11/site-packages/commitizen/cz/conventional_commits/conventional_commits.py /usr/local/Cellar/commitizen/$(cz version)/libexec/lib/python3.11/site-packages/commitizen/cz/conventional_commits/conventional_commits.py

cat <<"EOT" >> /usr/local/Cellar/commitizen/$(cz version)libexec/lib/python3.11/site-packages/commitizen/defaults.py

version_parser = r"(?P<version>([0-9]+)\.([0-9]+)\.([0-9]+)(?:-([0-9A-Za-z-]+(?:\.[0-9A-Za-z-]+)*))?(?:\+[0-9A-Za-z-]+)?(\w+)?)"
EOT

class: class ConventionalCommitsCz(BaseCommitizen)
method: def questions(self)
 "choices": [
 // other existing choices, NOTE: key should be of single character and should not be used by existing choices
 {
    "value": "chore",
    "name": (
        "chor: changes that do not relate to a fix or feature and "
        "don't modify src or test files (for example updating dependencies)"
    ),
    "key": "h",
},
{
    "value": "revert",
    "name": (
        "revert: reverts a previous commit"
    ),
    "key": "z",
},

Similarly scope and subject can be modified.

Add revert and chore in schema patters as well

    def schema_pattern(self) -> str:
        PATTERN = (
            r"(?s)"  # To explictly make . match new line
            r"(build|ci|chore|docs|feat|fix|perf|refactor|style|test|chore|revert|bump)"  # type
            r"(\(\S+\))?!?:"  # scope
            r"( [^\n\r]+)"  # subject
            r"((\n\n.*)|(\s*))?$"
        )
        return PATTERN

Fig Autocomplete

brew install --cask fig

You can opt-out of all telemetry and crash reporting by running:

fig settings telemetry.disabled true

Requires an emailId for the setup. 😒

nushell

if you work with lots of json, yaml, toml, xml, csv, ini, data files, then I would suggest this shell than any other shell, it gives you so many options to make your life easy.
It is a structured shell like PowerShell.
Nu views data functionally.
Rather than using mutation, pipelines act as a means to load, change, and save data without mutable state.
If you are used to any previous shell then this would help you get started: https://www.nushell.sh/book/nushell_map.html, https://www.nushell.sh/book/nushell_operator_map.html
Some of the programming language option on shell prompt: https://www.nushell.sh/book/nushell_map_imperative.html

# Linux and macOS
brew install nushell
# Windows
winget install nushell

After installing, launch Nu by typing nu

Python setup

pyenv manages multiple versions of Python itself.
virtualenv/venv manages virtual environments for a specific Python version.
pyenv-virtualenv manages virtual environments for across varying versions of Python.

brew install python@3
pip install --upgrade setuptools
python -m ensurepip --upgrade
pip install --upgrade pip

info:

Python has been installed as
  /usr/local/bin/python3

Unversioned symlinks `python`, `python-config`, `pip` etc. pointing to
`python3`, `python3-config`, `pip3` etc., respectively, have been installed into
  /usr/local/opt/python/libexec/bin

If you need Homebrew's Python 2.7 run
  brew install python@2

You can install Python packages with
  pip3 install <package>
They will install into the site-package directory
  /usr/local/lib/python3.7/site-packages

brew install python@2

Multiple python versions on local machine

# install py environment manager
brew install pyenv
# identify versions available
pyenv install --list
# Install python
pyenv install <python-version>
# verify installed version
pyenv versions
# To set global python version
pyenv global <python-version>
# To set local version, this is helpful when you have multiple projects depends on different python versions but at the same time, you do not want to change your global python version
pyenv local <python-version>
# check python version
python -version
# Once you close the terminal or open new terminal tab, this may not work, we need to initialize everytime we start a bash/zsh sessions
# add following in .zshrc or .bashrc file, similar to rbenv(ruby environment)
eval "$(pyenv init -)"
# installation location
ls ~/.pyenv/versions/
# To remove any python version
pyenv uninstall <python-version>
# To check installed python versions
pyenv versions

Virtual Environment for python

It offers flexibility in isolating multiple python environment and does not interfer with other virtual environment
Package installed in one virtual environment will not be visible in other virtual environment
Package installed in virtual environment will not be installed system wide hence it will not be available to all programs which uses system python setup.

System python installation path
/System/Library/Frameworks/Python.framework/

Homebrew installed python path
/usr/local/Cellar/python/<version>/

Let us use python3 for virtual environment
pip3 install virtualenv
OR upgrade
pip install --upgrade virtualenv

Setup virtual environment at any location, lets setup at home directory

virtualenv -p python3 ~/virtEnvPy3
python3 -m pip install --upgrade setuptools
virtualenv --upgrade-embed-wheels

Activate virtual environment

cd ~/virtEnvPy3
source bin/activate

Install any package for above virtual environment from terminal
pip install flask

Deactivate environment deactivate

on similar line we can create virtual environment for python2 as well

Now, if you want to extract which all packages you installed

pip2 freeze > requirements-2.txt
# OR
pip3 freeze > requirements-3.txt

If you want to install all packages from requirements.txt

pip2 install -r requirements.txt
#OR
pip3 install --user -r requirements.txt
# pip3 install help
# --user --> Install to the Python user install directory for your platform.  
# Typically ~/.local/, or %APPDATA%\Python on Windows.  
# (See the Python documentation for site.USER_BASE for full details.

Use pyenv along with venv [preferred if you have multiple projects with different python versions]

This is possible with pyenv-virtualenv plugin.
Installation of pyenv-virtualenv plugin, for more refer respective github page:

brew install pyenv-virtualenv
# Add following to .zshrc/,bashrc file
eval "$(pyenv virtualenv-init -)"

Create a virtual environment, make sure you have installed python-version from pyenv. This creates .python-version file to project folder.
pyenv virtualenv <python-version> <environment/project_name> e.g. pyenv virtualenv 3.11.9 LLM-demo

If you need all site-packages from parent python version to be available in virtual env then

pyenv virtualenv --system-site-packages <python-version> <environment/project_name>

Activate Virtual env pyenv local <environment_name>LLM-demo e.g. pyenv local LLM-demo

Verify

pyenv which python
pyenv which pip

GO setup

brew install golang or brew install go check version go version

Environment variables

Your Go working directory (GOPATH) is where you store your Go code/additional libraries. It is not mandatory to have your code at go-workspace. It can be any path you choose but must be separate from your Go installation directory (GOROOT).

mkdir ${HOME}/go-workspace
# GO projects/program will be stored
mkdir ${HOME}/go-workspace/src
# packaged object will be stored  
mkdir ${HOME}/go-workspace/pkg
# compiled binary files will be stored  
mkdir ${HOME}/go-workspace/bin

export GOPATH="${HOME}/go-workspace"
