Running Bundle without install Postgresql

When you use the gem PG in your Ruby or Rails project, usually is necessary install Postgresql before install the gems. But, if your DB is running in a docker, you does not need the Postgresql running local.

So, you need install a lib called 'libpq' on Mac OS before install PG gem. After this you can remove them. Command: brew install libpq

If you are using Debian, execute sudo apt-get install libpq-dev

*** If you don't use brew:

1. Install gem PG by the litle native app Postgres.app. To install access 
https://postgresapp.com/. After installation, execute the and can close them.

$ gem install pg -v <gem version `0.20.0`> -- --with-pg-config=/Applications/Postgres.app/Contents/Versions/9.4/bin/pg_config

Done!

PS.: To use PSQL, creates a symbolic link like bellow:


$ ln -s /Applications/Postgres.app/Contents/Versions/latest/bin/psql /usr/local/bin/psql

$ PGPASSWORD=<your-password> psql -h localhost -p 5432 -U postgres -c "\list"

Done again!

Manage your framework versions in a simple way

To install ASDF, follow the manuals and steps bellow...

$ git clone https://github.com/asdf-vm/asdf.git ~/.asdf --branch v0.4.3

# Add the two lines bellow on your terminal load file (e. .bashrc, .zshrc)
. $HOME/.asdf/asdf.sh
. $HOME/.asdf/completions/asdf.bash

# Adding plugins for ruby and nodejs
$ asdf plugin-add ruby https://github.com/asdf-vm/asdf-ruby.git
$ asdf plugin-add nodejs https://github.com/asdf-vm/asdf-nodejs.git

* I do not recommend you migrate ruby version from RVM, because is fast to install ruby versions.

# To install the tools ruby and nodejs, follow bellow steps

# Ruby

$ asdf install ruby 2.2.9

# Set ruby version locally - asdf <global | local> ruby <version>
$ asdf local ruby 2.2.9

$ ruby --version # ruby 2.2.9p480 (2017-12-15 revision 61259) [x86_64-darwin17]

# Nodejs

# (slow)Imports NodeJS release team's OpenPGP keys to main keyring
$ brew install gpg

** For debian, executes:

    $ sudo apt-get install gpg dirmngr

$ bash ~/.asdf/plugins/nodejs/bin/import-release-team-keyring
$ asdf install nodejs 8.10.0

** When install or update a new version and receive the error: No public key. Executes:

$ bash ~/.asdf/plugins/nodejs/bin/import-release-team-keyring

If does not work, try:

$ gpg --keyserver pool.sks-keyservers.net --recv-keys <key-that-has-error>


# Common commands

# Set a local tool version
$ asdf local <name> <version>

# List details of tools
$ asdf current

# Set a tool version
$ asdf local <name> <version>

# List the versions of a tool
$ asdf list <name>

# Detail of environment

When you set a version GLOBAL, this is set in ~/.tool-versions
Otherwise, if you set LOCAL, a file called .tool-versions will be saved in that folder.
I prefer always to use LOCAL.

Making Git diff beautiful

# Access https://github.com/so-fancy/diff-so-fancy

# To install
$ brew install diff-so-fancy

# Configure local git to use them
$ git config --global core.pager "diff-so-fancy | less --tabs=4 -RFX"

Done! $ git diff
