## Installation

- With ansible:

  ```bash
  bash dev/add_community.general.sh # only if community.general is not installed
  ansible-playbook -v -i <hosts file> ansible/playbooks/setup.yml
  ```

  This playbook can be tested [with a docker container](dev/README.md)

  Use `-e fix_annoyances=true` to fix some small annoyances (only run once)

- Manually (this only installs the zsh configuration):

  ```bash
  git clone https://git.decapod.one/brethil/dotfiles ~/.dotfiles
  echo 'DOTFILES=~/.dotfiles' >> ~/.zshrc
  echo 'source $DOTFILES/brethil_dotfile.sh'
  ```

A self-update mechanism is included. It asks for confirmation to pull the latest changes
from the git repo every two weeks. This also updates the git-sourced repositories installed
by the install script. The self-update routine can be called manually by calling

    dotfiles_selfupdate

If you do not want to run the installer script, you can just add source `brethil_dotfile.sh`
in your `.zshrc`. This requires antibody installed.

### Available Functions

0.  `cheat`: show cheat sheet for commands using cheat.sh (`cheat <commandname>`)
1.  Quickly edit/reload profile (`esource`/`resource`)
2.  `dockertags` list all tags for a given docker image
3.  `color` to print colored text (see 3. in the Misc section):

        color $Red "This will be printed in red"
        color $Yellow "This will be printed in red"

4.  `mecp` to copy files back to the machine from wich you are ssh-ing.
    For this to work an ssh tunnel with `Remoteforward` is needed:

         ssh -R 22:localhost:2222 YOURHOSTNAMEHERE

    or specify this in `~/.ssh/config` for a persistent configuration:

        Host YOURHOSTNAMEHERE
        Remoteforward 2222 localhost:22

    This can be enabled in `~/.ssh/config` globally for all hosts by uncommenting the relevant `Host * Remoteforward`.
    You might have to manually edit the username in the `mecp` definition in `functions.sh` if this is
    different between the two machines. `mecp` copies by default on the local machine on `~/Desktop/`

5.  Many more. Use `list_functions` to list defined functions and a small description

### Files/Folders

1. `~/bin`, `~/git`, `~/projects` folders
2. ssh config (`~/.ssh/config`):
   - Create ssh keys if not defined already
   - Keep connections alive by increasing timeout time
   - Include multiplexer to allow quick multiple connections to the same host
   - (Optional: Compression, this should allow more responsive shells with slow connections,
     but will slow things down when copying large files. My suggestion is to have compression enabled
     on a by-host basis in `~/.ssh/config`)
3. `brethil.zsh-theme`, `brethil-minimal.zsh-themes`, themes for oh-my-zsh.
4. `~/.dotfiles_functions`, `~/.dotfiles_aliases` are sourced by this dotfiles, allowing for custom functions/aliases
5. useful_commands contains a list of useful commands (the first rule of the tautology club...)

### Misc

1.  Colored output (via `grc`) for several commands.
2.  Easy names for ANSI color escapes (Black, Red, Green, Yellow, Blue, Cyan, Purple, White, CLEAR), for example:

        echo -e "${Green}This text will be green${CLEAR}"

    will result in green text. Use `$CLEAR` to clear previous escape sequences add B before the variable (check `colors.sh`)
    name to use **bold** and U to underline (examples: `$BRed`, `$UBlack` for bold red and underlined black)

3.  Autoupdate script running every two weeks, autoupdate function: `dotfiles_selfupdate` (or `git pull` from `$DOTFILES`folder)
4.  Automatic fix of the`SSH_AUTH_SOCK`environment variable:`~/.ssh/rc` is installed run on every ssh login,
    and updates a symlink pointing (`~/.ssh/ssh_auth_sock`). `SSH_AUTH_SOCK`points to this (set in`brethil_dotfile.sh`).
    The idea is that if the user is logging in using `ssh -A`, and using tmux, it will be possible to use
    the remote socket over different sessions by always using the symlink.
