#+end_src

To select fonts using a GUI, =gtk2fontsel= can be used:
#+begin_src bash
  yay -S gtk2fontsel
#+end_src

* =emacs= and =vim= - Text Editors
** Neovim
I use [[https://github.com/neovim/neovim][Neovim]] for all the small edits.

Installation:
#+begin_src bash
  yay -S neovim
#+end_src

The Neovim configuration can be found [[file:vim.org][here]].

Then install the plugin manager [[https://github.com/junegunn/vim-plug][plug]]:
#+begin_src bash
  sh -c 'curl -fLo "${XDG_DATA_HOME:-$HOME/.local/share}"/nvim/site/autoload/plug.vim --create-dirs \
      https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim'
#+end_src

And to install/setup all the plugins:
#+begin_src bash
  nvim +PlugInstall
  nvim +UpdateRemotePlugins
#+end_src

** Emacs
I use [[https://www.gnu.org/software/emacs/][Emacs]] and the [[https://github.com/hlissner/doom-emacs][Doom]] framework.

Install Emacs:
#+begin_src bash
  yay -S emacs
#+end_src

And then the Doom framework:
#+begin_src bash
  git clone --depth 1 https://github.com/hlissner/doom-emacs ~/.emacs.d
  ~/.emacs.d/bin/doom install
#+end_src

The Emacs configuration can be found [[./doom.org][here]].

SpellCheck with Aspell:
#+begin_src bash
  yay -S aspell aspell-en aspell-fr
#+end_src

* SSH setup
Generate a new SSH key:
#+begin_src bash
  ssh-keygen -t rsa -b 4096 -C "dehaeze.thomas@gmail.com"
#+end_src

Start the ssh-agent in the background:
#+begin_src bash
  eval "$(ssh-agent -s)"
#+end_src

Add the SSH key to the ssh-agent:
#+begin_src bash
  ssh-add ~/.ssh/id_rsa
#+end_src

* GnuPG
https://gnupg.org/

Install the gnupg package:
#+begin_src bash
  yay -S gnupg
#+end_src

Create a key pair:
#+begin_src bash
  gpg --full-gen-key
#+end_src

To configure the =gpg-agent= to cache the passphrase, edit the following file =~/.gnupg/gpg-agent.conf=:
#+begin_src conf
  default-cache-ttl 60480000
  max-cache-ttl 60480000
#+end_src

Install =Gnome-Keyring= to automatically unlock the GnuPG keys:
#+begin_src bash
  yay -S gnome-keyring
#+end_src

* =rofi= - Application Launcher
[[https://github.com/DaveDavenport/rofi][Rofi]] is a very nice alternative to [[https://tools.suckless.org/dmenu/][dmenu]].

Installation:
#+begin_src bash
  yay -S dmenu rofi rofi-calc
#+end_src

To be able to run sudo commands with =rofi= ([[https://github.com/DaveDavenport/rofi/issues/584#issuecomment-384555551][github issue]]), the command =sudo -A= can be used: it opens a =rofi= prompt to ask for the password.

For that to work, we need to add the following code to =~/.profile=:
#+begin_src bash
  export SUDO_ASKPASS=~/.local/bin/askpass-rofi
#+end_src

The =askpass= script is:
#+begin_src bash
  #!/bin/sh

  rofi -dmenu \
       -password \
       -no-fixed-num-lines \
       -p "$(printf "$1" | sed s/://)"
#+end_src

* =pass= - Password Manager
https://www.passwordstore.org/

Installation:
#+begin_src bash
  yay -S pass
#+end_src

Initialize the password store as a git repository
#+begin_src bash
  pass git init
  pass git remote add origin https://github.com/tdehaeze/pass.git
#+end_src

Gui Manager: [[https://github.com/IJHack/qtpass][qtpass]]
#+begin_src bash
  yay -S qtpass
#+end_src

Integration with Rofi: [[https://github.com/carnager/rofi-pass][rofi-pass]]
#+begin_src bash
  yay -S rofi-pass
#+end_src
Then we can add a shortcut to =rofi-pass= on i3 config.

Integration with Git: [[https://github.com/languitar/pass-git-helper][pass-git-helper]]
#+begin_src bash
  yay -S pass-git-helper
#+end_src

First, add the relation between repository addresses and entries in =pass=. This is done in the following config file =.config/pass-git-helper/git-pass-mapping.ini=:
#+begin_src
[github.com*]
target=github.com/tdehaeze
#+end_src

Then, add the credential helper on the git configuration file =~/.gitconfig= and add the default username for the repositories adresses.
#+begin_src
[credential]
    helper = !pass-git-helper $@

[credential "https://github.com"]
    username = tdehaeze
#+end_src

** Integration with other programs
Integrate pass in other programs is usually very easy, here are few examples:
- =~/.msmtprc=:
  - =passwordeval "pass email/dehaeze.thomas@gmail.com"=
- =~/.mbsyncrc=
  - =PassCmd "pass email/dehaeze.thomas@gmail.com"=

** Alternative - Bitwarden

* =buku= - Bookmark Manager
https://github.com/jarun/Buku

** Installation
#+begin_src bash

#+end_src

** Integration with Rofi
https://github.com/carnager/buku_run

*** Installation
#+begin_src bash
  wget https://raw.githubusercontent.com/carnager/buku_run/master/buku_run -o ~/.local/bin/buku_run
  chmod +x ~/.local/bin/buku_run
#+end_src

*** Configuration
The configuration file is here: =~/.config/buku_run/config=

** Integration with qutebrowser
[[*Integration with Buku][Integration with Buku]]

** Synchronization with a git repository
The database is stored in =~/.local/share/buku/bookmarks.db=.

We initialize a git repository in this folder:
#+begin_src bash
  cd ~/.local/share/buku/bookmarks.db
  git init
#+end_src

Then we create a script that will automatically add =bookmarks.db= and push to some repository: =buku_git_push=.

To automatically run the script every day, a systemd unit is used: =~/.config/systemd/user/bukugit.timer= and =~/.config/systemd/user/bukugit.service=

#+begin_src bash
  systemctl --user start --now bukugit.timer
#+end_src

** Import Bookmarks from Firefox and Chrome
From Firefox, export the bookmarks as html file.
Then import the bookmark file using =buku -i bookmarks.html=.
This will add a tag with current date to all bookmarks imported.
To remove them, use: =buku --replace '2018dec20' ''=

** Web Interface
Run:
#+begin_src bash
  bukuserver run --host 127.0.0.1 --port 5001
#+end_src

And then browse to http://127.0.0.1:5001.

** Configuration
https://hugo.md/post/the-perfect-weechat-setup-2/
https://robots.thoughtbot.com/weechat-for-slacks-irc-gateway

Use the command =/fset=

** Multi-line messages
Solution is provided here: https://github.com/wee-slack/wee-slack/issues/118
It uses [[https://weechat.org/scripts/source/multiline.pl.html/][multiline.pl]] script.
Then alt-enter is bound to insert a new line:
#+begin_src conf
  /set plugins.var.perl.multiline.magic_paste_only on
  /key bind meta-ctrl-M /input insert \x0a
#+end_src

And enter is bound to =magic_enter= that directly sends the message if its one line, and if its multiple line, waits a little bit and then sends the message:
#+begin_src conf
  /key bind ctrl-M /input magic_enter
#+end_src

** Send message using =$EDITOR=
https://github.com/keith/edit-weechat
#+begin_src bash
  mkdir -p ~/.weechat/python/autoload
  cd ~/.weechat/python/autoload
  wget https://raw.githubusercontent.com/keith/edit-weechat/master/edit.py
#+end_src

Then, on weechat, type =/edit=.

** Slack Integration
https://github.com/wee-slack/wee-slack

*** Installation
#+begin_src bash
  yay -S python2-websocket-client
#+end_src


#+begin_src bash
  cd ~/.weechat/python
  wget https://raw.githubusercontent.com/wee-slack/wee-slack/master/wee_slack.py
  ln -s ../wee_slack.py autoload
#+end_src

*** Add your Slack API key(s)
Log in to Slack:
#+begin_src conf
  /slack register
#+end_src
This command prints a link you should open in your browser to authorize WeeChat with Slack. Once you've accomplished this, copy the "code" portion of the URL in the browser and pass it to this command:

#+begin_src conf
  /slack register [CODE_FROM_URL]
#+end_src

Your Slack team is now added, and you can complete setup by restarting the wee-slack script.
#+begin_src conf
  /python reload slack
#+end_src

If you don't want to store your API token in plaintext you can use the secure features of weechat:
#+begin_src conf
