[[!template text="""that was difficult for me to replace.""" start="00:00:23.280" video="mainVideo-detached" id="subtitle"]]
[[!template new="1" text="""The problem for me was running shell commands""" start="00:00:27.120" video="mainVideo-detached" id="subtitle"]]
[[!template text="""in sub-processes of Emacs,""" start="00:00:30.120" video="mainVideo-detached" id="subtitle"]]

[[!template text="""using an external terminal.""" start="00:00:34.880" video="mainVideo-detached" id="subtitle"]]
[[!template text="""These situations,""" start="00:00:38.000" video="mainVideo-detached" id="subtitle"]]
[[!template text="""often revolved around long-running shell commands,""" start="00:00:39.688" video="mainVideo-detached" id="subtitle"]]
[[!template text="""either on my local machine""" start="00:00:43.354" video="mainVideo-detached" id="subtitle"]]

[[!template text="""When I was on a remote host,""" start="00:00:48.600" video="mainVideo-detached" id="subtitle"]]
[[!template text="""I would also rely on using the program tmux""" start="00:00:50.240" video="mainVideo-detached" id="subtitle"]]

[[!template text="""My main concern at the time""" start="00:00:57.280" video="mainVideo-detached" id="subtitle"]]
[[!template text="""was that I didn't want to having to avoid""" start="00:00:59.621" video="mainVideo-detached" id="subtitle"]]
[[!template text="""restarting Emacs,""" start="00:01:01.954" video="mainVideo-detached" id="subtitle"]]
[[!template text="""because I needed to wait for a process to complete.""" start="00:01:03.440" video="mainVideo-detached" id="subtitle"]]
[[!template text="""However, there was of course a lot of things""" start="00:01:07.800" video="mainVideo-detached" id="subtitle"]]
[[!template text="""I was missing out on by not using Emacs.""" start="00:01:11.200" video="mainVideo-detached" id="subtitle"]]
[[!template new="1" text="""Therefore, my solution to resolving""" start="00:01:15.800" video="mainVideo-detached" id="subtitle"]]
[[!template text="""the issue of occasionally having to leave Emacs""" start="00:01:19.760" video="mainVideo-detached" id="subtitle"]]
[[!template text="""led me down the path of developing the package""" start="00:01:22.840" video="mainVideo-detached" id="subtitle"]]
[[!template text="""Detached.""" start="00:01:26.188" video="mainVideo-detached" id="subtitle"]]
[[!template text="""The package allows Emacs to delegate""" start="00:01:28.321" video="mainVideo-detached" id="subtitle"]]
[[!template text="""the responsibility of creating processes""" start="00:01:31.160" video="mainVideo-detached" id="subtitle"]]

[[!template text="""It also makes sure to write""" start="00:01:36.840" video="mainVideo-detached" id="subtitle"]]
[[!template text="""the output of the process to a file,""" start="00:01:39.121" video="mainVideo-detached" id="subtitle"]]
[[!template text="""which we will see later on how that is being used.""" start="00:01:44.421" video="mainVideo-detached" id="subtitle"]]
[[!template text="""The package makes Emacs capable of""" start="00:01:48.254" video="mainVideo-detached" id="subtitle"]]
[[!template text="""attaching to these processes""" start="00:01:50.800" video="mainVideo-detached" id="subtitle"]]
[[!template text="""as well as managing them.""" start="00:01:53.120" video="mainVideo-detached" id="subtitle"]]
[[!template text="""In the package, each process is called a session,""" start="00:01:55.280" video="mainVideo-detached" id="subtitle"]]
[[!template text="""and inside of Emacs that is just""" start="00:01:58.880" video="mainVideo-detached" id="subtitle"]]
[[!template text="""an object with properties""" start="00:02:01.040" video="mainVideo-detached" id="subtitle"]]

[[!template text="""what working directory is used,""" start="00:02:04.688" video="mainVideo-detached" id="subtitle"]]
[[!template text="""where the output is stored, etc.""" start="00:02:06.720" video="mainVideo-detached" id="subtitle"]]
[[!template text="""The important aspect is also that""" start="00:02:10.240" video="mainVideo-detached" id="subtitle"]]
[[!template text="""these objects are being persistent,""" start="00:02:12.480" video="mainVideo-detached" id="subtitle"]]
[[!template text="""so they are stored over time.""" start="00:02:16.840" video="mainVideo-detached" id="subtitle"]]
[[!template text="""Today, I'm going to walk you through""" start="00:02:20.221" video="mainVideo-detached" id="subtitle"]]
[[!template text="""how I use the package and what advantages""" start="00:02:22.920" video="mainVideo-detached" id="subtitle"]]

[[!template new="1" text="""I'm going to start by opening up M-x shell,""" start="00:02:30.840" video="mainVideo-detached" id="subtitle"]]

[[!template text="""Instead of pressing return,""" start="00:02:46.920" video="mainVideo-detached" id="subtitle"]]
[[!template text="""I'll simply press shift return""" start="00:02:48.354" video="mainVideo-detached" id="subtitle"]]
[[!template text="""to let Emacs delegate the execution""" start="00:02:50.240" video="mainVideo-detached" id="subtitle"]]
[[!template text="""to the dtach program.""" start="00:02:52.600" video="mainVideo-detached" id="subtitle"]]
[[!template text="""Emacs will immediately attach itself to the process,""" start="00:02:54.920" video="mainVideo-detached" id="subtitle"]]
[[!template text="""and we therefore don't perceive any difference""" start="00:02:57.600" video="mainVideo-detached" id="subtitle"]]
[[!template text="""from when running the command as a subprocess.""" start="00:03:00.960" video="mainVideo-detached" id="subtitle"]]
[[!template text="""We now have the option though""" start="00:03:04.480" video="mainVideo-detached" id="subtitle"]]
[[!template text="""to detach from the session,""" start="00:03:06.588" video="mainVideo-detached" id="subtitle"]]
[[!template text="""and later on we can of course""" start="00:03:09.800" video="mainVideo-detached" id="subtitle"]]
[[!template text="""reattach Emacs to the session.""" start="00:03:12.080" video="mainVideo-detached" id="subtitle"]]
[[!template text="""For me, this addresses the core""" start="00:03:17.154" video="mainVideo-detached" id="subtitle"]]

[[!template text="""But let’s see what’s more""" start="00:03:23.800" video="mainVideo-detached" id="subtitle"]]
[[!template text="""the new workflow inside of Emacs can bring.""" start="00:03:25.040" video="mainVideo-detached" id="subtitle"]]
[[!template new="1" text="""The package supports multiple user interfaces""" start="00:03:30.800" video="mainVideo-detached" id="subtitle"]]
[[!template text="""such as Eshell and Compile.""" start="00:03:35.720" video="mainVideo-detached" id="subtitle"]]
[[!template text="""I will therefore switch to the Detached project,""" start="00:03:39.840" video="mainVideo-detached" id="subtitle"]]

[[!template text="""I will run it with detached-compile""" start="00:03:49.440" video="mainVideo-detached" id="subtitle"]]
[[!template text="""with the difference that""" start="00:03:54.040" video="mainVideo-detached" id="subtitle"]]
[[!template text="""I can detach from the compilation.""" start="00:03:55.800" video="mainVideo-detached" id="subtitle"]]
[[!template text="""One benefit of this new workflow is that""" start="00:03:59.800" video="mainVideo-detached" id="subtitle"]]
[[!template text="""I can get a system notification shown up here""" start="00:04:05.000" video="mainVideo-detached" id="subtitle"]]

[[!template text="""but then risking having forgotten it.""" start="00:04:19.040" video="mainVideo-detached" id="subtitle"]]
[[!template new="1" text="""How do we then see the output of a session?""" start="00:04:27.854" video="mainVideo-detached" id="subtitle"]]

[[!template text="""the command that we just built,""" start="00:04:42.954" video="mainVideo-detached" id="subtitle"]]

[[!template text="""If I press enter,""" start="00:04:54.480" video="mainVideo-detached" id="subtitle"]]
[[!template text="""we will get the output of the session here.""" start="00:05:01.521" video="mainVideo-detached" id="subtitle"]]
[[!template text="""And since it was run using compile,""" start="00:05:04.440" video="mainVideo-detached" id="subtitle"]]
[[!template text="""we also have compilation mode enabled here,""" start="00:05:07.200" video="mainVideo-detached" id="subtitle"]]

[[!template text="""potential warnings or errors.""" start="00:05:14.288" video="mainVideo-detached" id="subtitle"]]

[[!template new="1" text="""One thing that""" start="00:05:21.440" video="mainVideo-detached" id="subtitle"]]
[[!template text="""I have prepared here is that""" start="00:05:26.721" video="mainVideo-detached" id="subtitle"]]
[[!template text="""if I open up the user interface,""" start="00:05:28.920" video="mainVideo-detached" id="subtitle"]]
[[!template text="""we only see two sessions,""" start="00:05:32.240" video="mainVideo-detached" id="subtitle"]]

[[!template text="""running on the main branch.""" start="00:05:57.040" video="mainVideo-detached" id="subtitle"]]

[[!template text="""that you might have that.""" start="00:06:02.760" video="mainVideo-detached" id="subtitle"]]

[[!template text="""we can just mark these two and check,""" start="00:06:10.920" video="mainVideo-detached" id="subtitle"]]
[[!template text="""does this warning exist on the main branch or not?""" start="00:06:14.760" video="mainVideo-detached" id="subtitle"]]

[[!template new="1" text="""Now, another benefit, in my opinion,""" start="00:06:34.040" video="mainVideo-detached" id="subtitle"]]

[[!template text="""even more input needed to distinguish sessions.""" start="00:07:06.880" video="mainVideo-detached" id="subtitle"]]
[[!template text="""So, what I typically do then is""" start="00:07:16.880" video="mainVideo-detached" id="subtitle"]]
[[!template text="""press A to annotate the session,""" start="00:07:19.600" video="mainVideo-detached" id="subtitle"]]
