+[[!meta title="Play and control your music with Emacs - Damien Cassou"]]
+
+- Hi everyone.  In this lightening talk, I would like to present
+  MPDel, which is a user interface for MPD, the Music Player Daemon,
+  that's implemented in Emacs Lisp and runs entirely within Emacs.  So
+  it relies on Music Player Daemon, which is quite old because it's a
+  sixteen years old project serving music with many different clients.
+  So if I look at clients of MPD you see there are all different kinds
+  so this ?android? projects or web projects or GTK projects and a
+  curses project, web projects, so yeah many different kinds of
+  clients.  MPDel is implemented in Emacs Lisp, it's divided into
+  three parts.  So there is a library libmpdel, which is it's own
+  project.  That's doesn't propose any user interface, but instead it
+  proposes a set of primitive functions to build user interfaces on
+  top.  Then you have the screenshot here on top of the MPDel, so it's
+  mostly tabulated lists based, and then you have another UI which is
+  based on ?IV?, and I will present ?the? two user interfaces in this
+  context of this project.  So let's start the video by navigating the
+  music database.  So it's a simple job to get the list of all your
+  artists.  You can navigate with ?turned-out? shortcuts.  And you
+  have isearch obviously ?for? imenu, and so I can go to ?pink? sites
+  with quick shortcuts.  When you select your artists you can go to
+  which album by pressing return, and to go from an album to a
+  particular artist's songs, you also press return.
+
+- So that is going ?deep? from the album to the artist and from the
+  artist to the songs, and with carrots or shift-6 on my keyboard you
+  go up to the parent from the song to the albums, and from the albums
+  to the artists.  So the next thing we can see is the playlists, so
+  on the left you have the database, and on the right I will put the
+  playlist.  So for now there is nothing to listen to, and I will add
+  things in these lists, so we can add either artists, albums or
+  individual songs, so let's add one of my favorite songs, ?So equals?
+  from Pink Floyd.  So you can add it to the playlist, or add it
+  immediately stop playing it, so this time I want to immediately play
+  it, so I press P for play.
+
+- And then I will press the carrot to go back to the artists and add
+  some more music, I will add an album by Dire Straits.  So if I press
+  P now it will add all the album and also start with the first song,
+  but because I don't want to interrupt ?ecos? I will just press a to
+  add all the songs from this album.  What we want to do now is
+  manipulate the playlists, so for now ?ecos? has started playing and
+  I can modify the playlist to decide what will be next, so by default
+  it's Sultans of Swing, but I can change that for prioritization for
+  example.
+
+- Like that, so I can move one song, I can also mark multiple songs
+  and move them around.
+
+- It's also possible to play the next song and the previous song so
+  you have M-n to play the next. And M-p to play the previous one.  If
+  you wanted to delete a few songs from your album you can select them
+  and then press k for deletion, and then they are removed from the
+  database, not from the database, but only from the playlists.  With
+  t you can toggle the mark, so if I want to select everything by
+  ?except ...? I can just press t.  And t again to ??, if I want to
+  select everything I can always press t when nothing is marked, so I
+  can erase everything at once.
+
+- Something I can do now is display some information about the
+  currently played song, so I can press v wherever I am to get the
+  list of songs.  It's very important to notice that whatever view you
+  are in the shortcuts are always the same, so if I go back to the
+  navigator with n, I can press ?? information about the current song,
+  so v here, which ?? about the current song.  So you see that there
+  is the time, and the album and artist and ?? status, so if I pause
+  the music, it ?? pause.  And backplaying.  I can move forward and
+  move backward with M-s and M-v, I can do that slowly or fast with
+  different shortcuts, and from the current song you can press carrots
+  to go to the parents, so it's exactly the same shortcut as how we
+  were navigating from the songs to the albums and from the albums to
+  the artists, so it's carrots, and you go from the song to its album
+  and then from the album to the artist.
+
+- I tried when designing the shortcuts to make the keybindings do
+  always the same thing wherever you are, so if I press M-f now I will
+  fast-forward the current song, so the same shortcuts work the same
+  everywhere.  And if I press ?....? Another way to control the
+  current playlists or stop playlists is to use the Ivy based
+  interface so it doesn't pop up any buffer, but you can still
+  navigate your database and select the songs to play.  So if I start
+  the interface I get the list of all my artists in the minibuffer, so
+  I can choose for example MCC artists and the ?? ?king? and the song
+  I will pick this one for example, and there are many things I can do
+  from here, so I can add to the current playlist I can start playing
+  immediately, I can start and stop playlists, so let's see I just p
+  for playing it immediately.
+
+- So MPDel is mostly based on tabulated lists, which I really liked.
+  And after I implemented MPDel, I liked that kind of view so much I
+  decided to use the views for other kinds of packages, so I
+  implemented a database navigator, and also a network manager client
+  using tabulated lists, and I realized that all of those libraries
+  and tools they were sharing the same kind of code.  So I decided to
+  abstract away from all of those and I created navigel which makes it
+  very easy to implement tabulated lists if you have a model of your
+  domain data that you want to navigate.
+
+- There is a lightening talk at EmacsConf about navigel so I encourage
+  you to have a look at it if you're interested in how I reimplemented
+  MPDel so that it's much simpler, and how I implemented all the other
+  packages.  This is the end of my talk, I hope you liked it.  And
+  happy EmacsConf.

+#TITLE Restclient and org-mode for Api Documentation and Testing - Mackenzie Bligh
+
+- Hi everyone, my name is Mack, I am a back-end software engineer with
+  ?Tarot? in San Francisco, and I'd like to talk to you today about
+  how I integrate Emacs with RestClient and Org-mode into my daily
+  workflow for documenting and testing APIs.  All of the materials for
+  this talk can be found in EmacsConf 2019 repo with the url here
+  <https://github.com/mack1070101/emacs-conf-2019>.  This example uses
+  restclient.el, which is a domain specific language for working with
+  restful APIs and OBRestClient to provide the wrappers for Org-mode,
+  however these are just the wrappers for what I use, the principles I
+  demo here can work with any set of programming languages that's
+  supported by Org-mode and has network calls.
+
+- So I find this way of writing documentation great because it helps
+  people get into using Emacs and provides a shallow learning curve
+  without being overwhelming of how to use Emacs.  The second thing
+  that's great about it is it helps support maintenance of
+  documentation, because the documentation itself is actually used to
+  interact with APIs.  Therefore it's providing utility to developers
+  and they can use it and maintain it all at the same time.  As an
+  added benefit you have full Org-mode support for task management
+  doing things like exporting to other formats, building scripts via
+  tangling, as well as writing very complex API interactions by
+  feeding the output of one API into the input of another API.
+
+- I tend to favor using ELisp for simple things like building
+  requests, log in strings, things like that as you'll see.  I do try
+  to avoid using languages or tooling that aren't integrated with
+  Emacs, however if it makes my life easier I'll use ubiquitous tools
+  like curl and jq as needed.  I've included a mock server that I
+  already have running here, and you can find details about how to get
+  that set up if you're interested in the repo and link up above.  So
+  let's jump right in.
+
+- Here is provided a sample document for a stock trading
+  application.  We've got
+
+To be completed later.
