[[!template text="""I think of it as a text pattern""" start="00:01:05.160" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""that has some extended meaning.""" start="00:01:06.800" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""When you see the pattern in the text,""" start="00:01:08.920" video="mainVideo-buttons" id="subtitle"]]

[[!template text="""When you press the button,""" start="00:01:12.800" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""something related to that meaning happens.""" start="00:01:13.880" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""It can be jumping to some place,""" start="00:01:16.880" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""opening an external tool, doing some computation.""" start="00:01:19.000" video="mainVideo-buttons" id="subtitle"]]

[[!template text="""associated with the pattern.""" start="00:01:24.160" video="mainVideo-buttons" id="subtitle"]]
[[!template new="1" text="""To make it clear, let's look at some examples.""" start="00:01:29.920" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""Let's start with something that is maybe so obvious""" start="00:01:33.320" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""that you don't even think of it as a pattern: a file name.""" start="00:01:36.080" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""When you see such a string in text,""" start="00:01:39.600" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""you will naturally associate it with a file on disk,""" start="00:01:41.360" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""and if you would click on it,""" start="00:01:45.360" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""you would probably expect that file to open.""" start="00:01:46.720" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""In the first sentence on the slide,""" start="00:01:52.680" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""you might recognize the file name""" start="00:01:55.120" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""for the bash initialization file, ~/.bashrc.""" start="00:01:56.840" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""Hyperbole comes with built-in support""" start="00:02:01.760" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""for recognizing files and directory path names""" start="00:02:03.840" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""as implicit button types in text.""" start="00:02:06.520" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""For Hyperbole to take action on the button type,""" start="00:02:08.680" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""you move the cursor within the button""" start="00:02:11.760" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""and press M-RET or use a mouse click.""" start="00:02:13.440" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""So let's try that.""" start="00:02:16.320" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""Similar for the path, /usr/local in the next sentence.""" start="00:02:22.360" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""That will open the corresponding""" start="00:02:27.720" video="mainVideo-buttons" id="subtitle"]]

[[!template new="1" text="""Other examples of built-in implicit button types""" start="00:02:37.080" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""that Hyperbole recognizes are email addresses,""" start="00:02:39.760" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""web addresses, requests for comment documents""" start="00:02:43.720" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""in the form of RFC followed by a number,""" start="00:02:47.320" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""GNU debbugs issues, plus many more.""" start="00:02:50.120" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""These are some examples""" start="00:02:53.040" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""of implicit button types with built-in support.""" start="00:02:55.360" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""I list them here to give you an idea""" start="00:02:58.080" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""how the text pattern in itself is enough""" start="00:02:59.920" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""for the system to recognize it""" start="00:03:02.480" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""as something actionable.""" start="00:03:03.960" video="mainVideo-buttons" id="subtitle"]]
[[!template new="1" text="""So as shown, Hyperbole has built-in support""" start="00:03:10.120" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""for implicit buttons.""" start="00:03:12.480" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""There's only one problem here.""" start="00:03:14.040" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""The behavior is predefined.""" start="00:03:16.120" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""There is of course a trade off.""" start="00:03:17.920" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""It is convenient to get""" start="00:03:20.240" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""many button types out of the box""" start="00:03:21.560" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""with likely good standard behavior""" start="00:03:23.480" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""and that works in many places.""" start="00:03:25.520" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""But what if you would want to create""" start="00:03:27.680" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""your own completely new mapping,""" start="00:03:29.360" video="mainVideo-buttons" id="subtitle"]]

[[!template text="""It is here that Hyperbole's support for creating""" start="00:03:32.880" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""new implicit button types comes in.""" start="00:03:38.120" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""For the full pattern matching button type,""" start="00:03:41.280" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""like for the filename and examples we just looked at,""" start="00:03:43.360" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""you need to define the implicit button""" start="00:03:46.720" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""using the macro, `defib`.""" start="00:03:48.755" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""The downside of that is""" start="00:03:50.920" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""you need to code at the elisp level.""" start="00:03:53.280" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""However, if you are creating a new pattern""" start="00:03:54.920" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""that has well-defined delimiters,""" start="00:03:57.240" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""there is support for that in an easier way.""" start="00:03:59.120" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""These support functions, or rather macros,""" start="00:04:01.360" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""are `defil` and `defal`.""" start="00:04:03.800" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""We will look at those macros soon,""" start="00:04:06.240" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""but first, my definition of personal data.""" start="00:04:08.440" video="mainVideo-buttons" id="subtitle"]]
[[!template new="1" text="""I think of personal data as something""" start="00:04:13.400" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""that you would like to link to,""" start="00:04:18.200" video="mainVideo-buttons" id="subtitle"]]

[[!template text="""supported by any known tool.""" start="00:04:21.440" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""It might be stored on a web server, local storage,""" start="00:04:23.360" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""or could even be some computation""" start="00:04:26.920" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""rather than a link.""" start="00:04:28.680" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""What all these cases have in common is that""" start="00:04:29.400" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""you want to be able to reference it""" start="00:04:32.200" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""in a short, and for you, descriptive way.""" start="00:04:34.240" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""So when you write text, you can use""" start="00:04:36.640" video="mainVideo-buttons" id="subtitle"]]

[[!template new="1" text="""This might be a bit abstract,""" start="00:04:44.480" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""so let's look at an example.""" start="00:04:46.600" video="mainVideo-buttons" id="subtitle"]]
[[!template text="""Suppose you have a flat file structure""" start="00:04:48.080" video="mainVideo-buttons" id="subtitle"]]

[[!template text="""In the data folder, we have two files""" start="00:04:54.520" video="mainVideo-buttons" id="subtitle"]]

[[!template text="""To make the pattern stand out in text,""" start="00:05:10.920" video="mainVideo-buttons" id="subtitle"]]
