In my previous episode I discussed how to use the book.
I gave you the nitty and the gritty.
I gave it to you in excruciating detail.
I think it took me about an hour when all I really should have said was download
the book, start writing the book, put it in the pan dock and you're done.
That's that episode, pretty much summarized.
But gosh, there's so much more about the book to talk about because there's kind of the
why of the book.
I mean, that was the how of the book, but there's this why question that keeps burning
people, because I mean, even today I see projects migrating away from dock book for
something simpler, something that they perceive to be simpler, such as markdown or ask
e-dock or restructured text.
And I'm not the kind of person, at least in this case, to say that those are bad alternatives
because I've actually used those alternatives quite frequently myself.
I use them to this day, to be honest.
There are many times where I'm making notes or writing down a recipe or something.
I'm not going to do that in dock book.
I'm not going to write a whole article on how to make cinnamon sticky buns.
You know, I mean, I just want something quick and easy.
So I write that in markdown.
And it also helps that my next cloud installation can parse that markdown into something pretty.
And so it kind of all integrates with the notes app of next cloud, which is a great
one.
You should check it out.
So markdown is a valid thing.
It's not the most valid thing, but it's a valid thing, restructured text, great.
Ask e-dock actually, I've never used it, but let's ignore that fact for now since I'm
going to be commenting on it in this episode.
So dock book is great.
It just might not always be the thing that you want to use.
And I think that's understandable, and I think that's totally valid.
And I think it's something important to remember.
So this is not an episode on why dock book is the best, and it's the only thing you should
use.
It's simply why is dock book still relevant?
So let me tell you how I found dock book.
I found when I first had started using Linux, one of the first purchases that I made was
a Slackware DVD and a Slack book, or I think it was just called Slackware Essentials or something
like that.
And that book has gone with me so far.
I mean, that thing has been in my gym bag, my gym bag that held all my books for years
and years and years.
It's gone to me with me, with me, to jobs, many different places.
It's been all over the place.
It's no longer something that I own because I had to move, and it wouldn't fit in my suitcase.
No physical books fit in my suitcase.
There were no physical books traveling with me.
But in investigating how the Slack book was written, I saw that it was written in something
called SGML and processed with something I think it was called Jade.
And researching that further led me to the later incarnation, I guess, of those tools
or something called Docbook.
And Docbook was just this set of rules, really, written by a guy named Norman Walsh, and
people seemed to use it for technical documentation.
So I thought, you know what?
It's a good thing to learn.
So I started learning it, and I started using it, and I actually really, really liked it.
And I liked it, I think, to be fair.
I liked it because it was the only thing that I knew of at the time.
And to be fair, again, it might have actually been the only thing at the time.
I remember distinctly hearing about what I gathered was a new concept when I started
going to technical conferences, this markdown idea, and no one seemed to know what this
markdown idea was.
So I kind of got the impression that it was just coming out.
And I could look that up.
I guess I could look when markdown hit the world scene.
But I really think that I might have been there for sort of the birth of markdown.
And by there, I just mean sort of in the tech scene.
So I learned about Doc Book.
I loved it.
I didn't really know of any other alternative other than word processors.
And I knew that I hated word processors.
So now let me give you a little bit of history about myself with word processors.
So word processors I didn't actually use early on.
I just used this handoff computer that my dad didn't want to use anymore because it was
too old and too clunky.
And the word processor on it, such as it was, was kind of like this command liney thing
that you would, and you tagged things, and then when you printed it out, those tags would
turn into formatting options.
So my very, very first experience with the idea of, oh my gosh, I can type stuff into
a computer and then print it out, and I don't have to do it with handwriting, was this
program that, I mean, I don't know what it was, I don't remember.
But it was running, you know, kind of in a, you know, it was like a black screen with
like, just, you know, plain text, like console text, it wasn't like a font or anything.
You know, and that was how you did it.
So I was very used to this idea of being explicit in how I want my presentation to end
up.
And then when word processors kind of got introduced to me, I thought, okay, well, this is
kind of cool.
There's a lot of menus here.
I don't really like that, but, okay, this is kind of interesting.
And I kind of fell into it and I started using it because you think, you know, in your
foolish youth, you think, well, I should learn this stuff because all my teachers tell
me that this is the big thing in the business world and I guess that's what I'm going to
do.
And so you're like learning all this stuff and, you know, within two days you know more
than the teacher, that sort of thing, we've all been there.
And give it about five or seven years and I go to open up a file that I'd done and suddenly
the thing won't work anymore.
Thing is, things deprecated.
The whole file format doesn't work.
There's no application on the face of the planet that will open that file format.
Why?
The file format was closed and the application that gave birth to that format has closed
its doors and it no longer works or it's updated and decided out of that old format
who cares about that.
Nobody used that anyway.
We'll just do this new one.
That happened to me about five different times.
I swear to you and I've heard other hosts on HPR and in other podcasts say similar
things.
And in the Fedora project, I know a couple of people who kind of overheard idly say,
like, oh yeah, I remember back in the day when I was using this and that got deprecated.
And that's like, I feel like that there's a not insignificant number of people who have
been pushed towards open source from that very experience.
It's the idea that just something as simple as a word processor document has been, has
given us so much trouble that we won't touch word processors anymore.
And I'm boldly and proudly one of those people.
I will not touch a word processor except in very rare.
I might not actually touch it.
I can't remember the last time that I've authentically used a word processor and I just
don't do it.
So Docbook was very exciting to me because it was plain text.
So I knew it would open because I mean you go online and you look at BBS postings from
1983 and they still open.
They still work.
There's nothing deprecated about it.
And the ASCII art that they include is still there.
It's still exactly as it was before, you know.
That's powerful stuff.
So I knew plain text was good for longevity and this Docbook stuff just seemed so exciting
because I thought I could do this Docbook and then put it through a processor and it will
translate all the tags for me and then I can have output in any format that I want, including
plain text without all the tags.
But it'll still maintain that structure.
So that was really exciting and I absolutely loved it.
And then later when I found out about Markdown I thought wow that's a really powerful idea
now because Markdown doesn't have all those tags.
It's just a way for us to all sort of agree, hey we're going to write plain text but we're
all going to agree we're going to do a gentleman's agreement here that we'll all do it in the
same way.
We'll do it in a predictable and repeatable way.
So instead of just doing a chapter heading we'll put a hash in front of the chapter.
And if it's a section within a chapter we'll do two hashes.
And then another section within that section we'll do three.
It's very, as I said in the last episode, maybe not intuitive but once you see what
it's, you see the structure you kind of, you see the logic in it.
And the same maybe true for Docbook but Docbook's a lot more verbose than just hey put a hash
in front of your header and that's now you've got a chapter heading and we'll even parse
that as a chapter heading and we'll put it in your table of contents for you if you want
us to.
It's a powerful stuff and that's very appealing and it's very attractive and very exciting.
And hey I'll admit it I've flirted with Markdown I've tried it you know I spend a little
bit of time with Markdown just like everybody else.
No but seriously I do use it still.
I think the problem is that the way that Markdown has kind of talked about in a lot of
communities is like it is the end of all other formats you know it's like this great
thing and it's simple and it's so it doesn't need to be that complex.
Because it's Markdown or it's Restructured Text or it's Ask You Doc and we do it right
because we're simple and we're minimalist and you can learn this in an afternoon.
And yeah that's true sure I mean you I will admit you have one page print out of a
Markdown cheat sheet and you're probably good to go you'll probably be writing a document
within within the hour definitely because it is just there's there's no declarations
there's no there's no namespacing there's no tags it's just it's like hey if you want
to do a chapter heading you do this if you want to do a section heading you do that that's
all very easy but then you do have to stop now mind you when you're doing your URLs right
because you might think well this will be easy I just do a you are oh wait how do I do
an embed like an actual how do I make a word a hyperlink like I know that it'll automatically
link HTTP colon slash slash but how I want I don't want to I don't want the readers see
the HTTP slash slash I want them to just see food when they click on food it'll take them
to example dot com and so you have to look that up and square bracket food square bracket
parenthesis HTTP colon slash slash example dot com close parentheses and now that works
and and again looking at it after the fact you're like yet I see what they did there square
brackets was the term parentheses was the sort of the expansion of that term which parentheses
kind of are used for in real life anyway so it totally makes sense and it reads well it reads
as if though it was plain text that you probably wouldn't write it exactly that way in real
life you would probably put like food space parentheses example dot com close parentheses
and that would be like the totally natural way to do it so mark down is doing a little bit
of scoping there with the square brackets but it's still it's all within the same realm
it's it's within the same within that margin of like yeah I could get used to that and
you do get used to it you get used to it very quickly and that's the the power of mark
down the problem with mark down though I I would argue first of all is that you show
me a person who has used mark down and has not fallen back on html it can't be done you
won't be able to find anybody under the sun who's who's done that I mean not anyone sure
I mean someone has written a read me dot md file forget hub or get lab and have they have
not had to use an html tag but I'm saying someone who's really working in mark down it's
a classic classic trope that they're going to fall back on html eventually and once
you start falling back on html then you almost you know it kind of it's an illusion shattering
moment because everything was going so well and then suddenly you're typing out tags
again and then you're just like wait well so why am I using mark down again and that's
what happens I I've seen it happen several times because at my just my previous job we
had to juggle several formats and one of them was mark down and it would every single
time every single time someone would be writing something about this plugin that they'd
written for you know the 3d stuff and and and they would be trying to do something and
it wouldn't it just mark down just would not the processor for mark down processors for
mark down just they're not smart enough or the processors are processors right the the
mark down spec itself just doesn't have an allowance for certain certain things I can
give you an example and this may be like a painfully common example maybe maybe you've seen
people complain about this online already and there's probably an answer out there someone's
probably already sort of come up with a solution or whatever well there's a solution but
I mean someone's probably explained this one away but I'm going to cite it anyway just
because it is a pretty common thing and I feel like it's representative of some of the quirks
so let's say that you're writing a mark down file so you've got your hash and then this is
mark down okay so there's your chapter heading cool that's easy and then you've got your
paragraph so that's just complete you know all the way to the left and you just let's see
what this mark down does and then you start a bullet a numbered list rather so you want a list
that says one two three four five six with six items but on the third item you want to have a code
block that's a pretty common thing especially in the technical world right you mean you if you're
describing how to use a software for instance on Linux especially you might want to have a code
block in your bullet list in fact it might be something so common that you that's the main
thing that you want to do with mark down because maybe you're writing about a command line application
so yeah it could be super common so we'll do a one dot and then this is item one and then one
dot this is item two and one dot this is item three mark down it doesn't matter the numbers that
you use as long as it's an integer and a dot and that's it'll it'll order it correctly so this
is line three of the list and it's going to have a code sample so now as we all know
the code insertion method for mark down is four spaces from the left margin so one two three four
so now your four spaces in and you do I don't know dollar sign hello world and then you go to
the next line all the way back to the left margin one dot this is the fourth item one dot fifth item
one dot six item okay you render that and the hello world item will not be a code block it'll
just be part of the previous line so it doesn't even see really that it was supposed to be a block
within that list so then maybe you say okay well that didn't work so you do you you buffer it
with some blank lines so we go back in and we put a return after oops after the third item
and a return after the code block and so now we got one one one blank line and then our code
block four spaces in and then space within a blank line and then one one one so render that
and it does that but now the code block is not a code block it's just a paragraph in the middle of
the or map might be a code block actually but now the list does not continue into sequentially so
it's one two three code block one two three that's not what you wanted you wanted one two three
code block four five six okay so you open it back up you fiddle around with it you complain you
look it up on line on forums and finally you realize that the answer to all of your problems
is to do the blank line after the third item and then one two three four five six seven
spaces and then the XML HTML code rather code tag HTML tag code and then dollar sign hello world
and then close the code tag and then close the code tag and then continue with your
blank line and then continue with your list so now I'm going to pipe that through will not
literally pipe I'm going to send that through pan doc and end up with a test dot let's just do
PDF for rendering nope can't do that let's do HTML instead there we go um
and then let's look at that in something let's use conqueror
and you've got one two three and then the code block and four five six so it completely worked it
totally worked um and it only worked because you used probably some magical number of spaces I'm
not even sure if that actually matters that was just that's where I ended up let's put it that way
and then you used HTML and that happens all the time I've never seen a person seriously using
markdown who has not had to fall back on HTML tags and you think well that's not that big of a
deal because everybody knows HTML blah blah blah but I mean that's actually exactly the the point
of markdown is that you're you're it's supposed to be plain text that then gets parsed into something
into many other formats so if we're falling back on HTML for every time it's important then why
are we using markdown honestly um restructured text does a lot to answer those problems and I don't
know if markdown is something that just isn't maintained anymore or if it's just had so many
forks at this point that the original maintainer just doesn't care I don't know I don't know why
markdown is it's kind of lacking in the ways that it is or maybe it's feature complete in the
eyes of the maintainer any D just doesn't feel the need to make it more complex with with different
use cases but um restructured text which is used by Python the Python community does a lot of
their documentation restructured text with with Python's finks and and that works really well
but it's like looking at it if I had to put it on a scale between or a spectrums between
dockbook and and markdown um then it would be maybe sort of well somewhere in the middle um
and it kind of you know you look at it and it's like yep that's that looks like plain text I mean
the chapter headings are are underlined with dashes so that delimits those and paragraphs look
normal and the code blocks are prefaced with this weird the sort of dot dot code colon sort of thing
and then it's indented in a funky way I see what they're going for there and they're kind of labelling
it so I understand what that means but there yeah there are a lot of like weird little markup
things that you have to do in restructured text to to to to be to have valid restructured text RST
so it is it's it's it's better I would say but it's not I wouldn't say it was perfect because
because there are quirks to it as well I have found and a lot of times once again you kind of end
up falling back on html because that's just kind of in the end what works best and so if you're
using html I just I keep asking myself why are we using the the markdown type formats then why
don't we just use html and get it over with so asky dock I've never used so I actually can't
complain about asky dock although if I use it for a day I'm sure I could find something although
maybe not maybe it's great you know I mean it has been highly regarded by many people I actually
know some people who write an asky dock and then I think translate it over to dockbook and and
that's totally valid I've actually done that before myself not not asky dock I've done it with I
think plain text actually I used to write and plain text and then process it into dockbook and
then go through and correct all the dockbook tags point being is that I don't believe that these
quote-unquote simplified methods are actually all that simplified and especially that that
becomes especially true if you start actually caring about the style which again is true of dockbook
as well but I just find people saying oh markdown and re-chartored text and asky dock they're so simple
you'll never you know you'll never look back and it's kind of like well I've been down that road
and I have looked back because I've been to some place where I I'm super super happy with the
workflow with the tool chain until I decide well I would really rather that the color of that
heading to be red instead of black and then it's just you think well that's super simple I can
just do this nope that doesn't work well okay I can do this nope that doesn't work if it gets
at the template file okay well I'll do that well now you have to learn dock utles or something
like that you know it's just it it becomes this big big project and at that point the simplicity
of the format basically falls apart for me and I think well there's no point to it anymore now I
might as well use something that is highly structured and I'll just keep using that because the
there's no there's no advantage to this other thing yet so my default is dockbook obviously but
it might not be your default should it be your default well yes it should so as I think I might
have mentioned briefly in the previous episode or I might not have dockbook has a lot of what
would be called semantic information and that is to say that in HTML for instance or even you know
like in markdown let's do markdown because I'm picking on markdown in in markdown you might be
typing something and you might think okay well there's this thing here there's this variable name
an environment variable specifically and I want to I want to somehow separate that from the
rest of the text and that's a pretty natural thing for us to try to do for one reason or another
sometimes we want to do it just because we feel who this is a super important term I want to make
it blink and other times we think well it really is confusing if this thing is not highlighted in
some way people will not understand where the invariant the environment variable begins and
where the rest of my text ends or the environment variable ends and where the rest of my text begins
so so you might want to do limit that some some way separate that some way from the rest of the
the the document so you might go in there and give it two asterisks to make it bold or you
might go in there and give it two back ticks to make it a code sort of thing and that's fine
and that kind of works and it produces on the you know once you render that through your processor
it it makes that environment variable name bold or monotype or whatever it does monospace whatever
and that's great and and that's down to you know styling and stuff like that but but but you've
got and even in the source code you do have some indication hey this word is special it's either
got asterisks asterisks around it or it's got back ticks around it or or three quotes I think is
what it is and restructured text of three single quotes so or maybe it's two back ticks and I don't
know but it's it does have something there but in doc book you could say okay I want this
environment variable to be separate from the rest of the text and give it an in var tag e in
v a r tag now you know exactly what that environment variable is not just by looking and saying oh
yeah it's got some asterisks around it you know that it's an environment variable because it is
tagged as such the same the same goes for a lot of different things key combinations like control
c control x control control z control x I said that already if anything like that you can tag
that stuff in doc book as a keyboard combination a key combo and then you can tell exactly what
what that is is it a what kind of key is it is it a is it a is it the thing that is literally
printed on the key or is it some other kind of key you know you can get really really specific
with the data that is contained in your document and there are two great reasons three great
reasons for that one is consistency consistency and documentation especially technical documentation
but also other kinds of documentation it's really really important people want to see things
we when you read something and it's consistently laid out or or or or processed or rendered or
whatever that makes you think that there's some form of professionality professionalism in that
document you know they've they've actually taken the time to make sure that when they said control
c yes on the page on the page that I've just turned the previous page it was you know it looked
like this and now when I turn the page and control c is there again it still looks like that every
time I see control c it's exactly like that or every time I see an environment variable it is
it is styled the same way so there's there's a virtue there to to making sure that you're using
the same tag for the same kinds of elements ensure you could do that and mark down as well or whatever
but with with doc book you're you're you're doing it because of the tag itself rather than just
remembering okay every time I use a keyboard one I'll do two asterisks every time I do any kind
of variable name I'll do the two backticks and that's how it will be no with doc book you've got
specific tag types around specific terminology or specific uh yeah words or letters or whatever
and then in your styling you can do whatever you want to with that and it won't matter
because it's got a tag especially for it and we were really bad about that with html you know we
we very frequently I see source code in html it just abuses term tags you know they just they just
they don't really know maybe there's not a tag for something but they want to so they just
repurpose tags you know well nobody uses the e m tag in my business so I'll just I'll repurpose
it in my CSS and anything that is the e m tag will we won't italicize it we'll just use it to do
such and such instead and you know I've seen that all over the place so doc book avoids that kind
of thing because it's got a tag for so many different things and that's great and heck I mean
as xml so you can actually add your own tags I mean doc book frowns upon that because they're they
they say if you modify doc book you're not using doc book but I mean you could add your own you could
bring in your own name namespace and have your own tags so that's a possibility and that kind of
speaks to the next benefit of all this which is the semantic meaning of data you know the actual
fact the fact that the actual term itself is of a certain kind so maybe it's a product name or
maybe it's a vendor name or something like that it becomes meaningful now because it is tagged
in certain way and so now you're not searching just by what did we do to our product names do we
make them emphasis yeah I think so okay well let's look for all the emphasis tags and then within
those emphasis tags we'll look for all the product all the the business names or whatever we're
looking for this time you you actually know what you're looking for because it is tagged in a certain
way and here's a true story from New Zealand it's quite quite funny but it's it's I swear it is a
true story there was a company called telecom or yeah telecom or something like that telecom
and they got bought by a company called Spark so for about three days on the internet all their
public documentation and their website and everything everywhere every time the word telecommunication
appeared instead of saying telecommunication it said spark communication I mean you can see
exactly what some code monkey did they did a find and replace on the the business name telecom or
telecom and completely didn't think of the fact that telecom was a very very common prefix in their
industry for the word from which it comes telecommunications and so when they did a find and replace
blindly on every document in their business they turned every instance of the actual word telecommunication
into spark communication and it was hilarious and embarrassing and and you could just completely see
people just you it was just a face palm a moment you know it was just like yeah I see what you did
there and I think you should have maybe thought about that first and I can only imagine like when
someone found out what they had done it must have been just really hoping that nobody noticed but
yeah I mean that's the kind of thing that that that can happen when you have no idea what the
content of your document is so with doc book you can actually tell you know you can identify
what the content is rather than just having random words in it and maybe that's important to you
maybe it's not but that's the third thing which is um I don't know I think of it as future
proofing but I guess technically it's it's not really but in a way it's it's opening yourself up
for future uses of data that you might not actually consider yet so for instance
five years ago maybe or not 10 years ago 10 years ago there was no real concept
of of this of the idea that that in a web page you might have a phone number and you might want
to make that phone number clickable because why would any why why would that be something like
why would you need to click a phone number phone number you use on your phone you don't use it on
the web and then suddenly smartphones started coming out and people started actually interacting
with the web on their smartphones and it became almost a problem that no one could identify where
a phone number was versus a date or a zip code post code whatever um and they thought oh man
wouldn't it be neat if we had a tag for this and of course such a tag has since come about and now
we can tag things as a telephone number you can click it and it goes to your cell phone telephone
app and and you can dial it without actually you know pressing the buttons you just clicked on
a number but if we if we think of that really broadly outside of that specific example I mean the
same can be true for for documentation uh that you're writing right now there may be concepts in
there that you'll never think you know why would I possibly need to do this with with all of this
all with all of these words they're just words but I mean at some point you might find that
that that some of that data becomes important if identified and with something as explicit
and verbose as doc book is you're kind of doing that inherently you know you're actually
classifying the data that you're typing into your document rather than just typing data into
the document and just saying ah the reader will the reader can just figure out the the context of
all or the the the the type of all of this type and I mean they can and that's great but that's a
human that's the human reading the words what about the computer that's going to read the words
at some point and that's why doc book to me is is really a clever system so why am I even talking
about doc book or markdown or restructured text or ask you doc at all and that is an important
question because a lot of people are just thinking well I don't even want to get involved I'm just
going to write in plain text or I'm going to write in a word processor so first of all word
processors today are writing in XML you don't know it you don't want to think about it but it is
that's what's happening underneath the underneath all that fancy gooey stuff that you're looking at
it's it's most of the word processors are yeah generating XML and you can look inside certainly
of an ODT it's just a zip file you can unzip it and look right at it it's a bunch of XML you can
look it's inside of a an EPUB and certainly that's got a bunch of HTML in it I think a little bit
of XML for that that index part and then you can I think doc X is famously XML as well I'm pretty
sure I mean I could be wrong I haven't really dealt with doc X in any recent time but I'm pretty
sure that's what the X actually stands for is XML so XML is is here to stay man but I mean really
it's it's it's it's something that we're all using secretly anyway but aside from that
technicality the important thing here actually whether you're using doc book or markdown or
researcher texture ask you docs is structure and predictability a long time ago I was trying to
get rid of all my physical books because they were heavy and I was tired of carrying them around
so I wanted them all really on my computer because I didn't have an e-reader at that time so I
thought if I just get these books into some format that I can have them on my computer they'll
be easier to carry around and at the time this was a very long time ago that was really hard to do
because the publishing industry hadn't really jumped on board the whole concept of let's do this
digitally yet in fact it's pretty arguable that they still have yet to figure that out luckily it
doesn't really matter because there are enough independent publishers at this point to really
make that almost a moot point for for what I'm interested in but at the time I thought okay well
I'll just I'll take pictures of them on a digital camera and then I'll load them in and that's
what I'll do and yeah I had a digital camera even that long ago because I was in film school at
the time so it kind of worked out so I thought well that's what I'll do that'll be great
you know to make my own little PDFs and I actually did that almost to a whole book
and the resulting PDF file was something like 200 megabytes or something insane like that because
they were all like PNGs so I made them all JPEGs and I I spent like a week trying to figure out how
to process you know 200 images because I wasn't doing Linux yet so I had no idea how to do that
finally sort of figured it out anyway long story short it was not working well for me eventually
I found that some people were doing that like on Gutenberg like you could find lots of books on
Gutenberg and they were in HTML and I think well I don't think I know TXT and HTML formats at
that time I don't think there was any kind of ebook format really I mean there may have been
something but certainly nothing I was familiar with and so I did I I've read a lot of books
from Gutenberg so and and that was just plain text but one thing I was I started to notice
about plain text was that it wasn't predictable so once I got savvy on Linux and figured out oh
I could script stuff cool so I went to go take some of my plain text books and and process them into
some other formats you know like HTML let's say I don't actually remember but let's say it was
HTML and I was finding that you know in one file the chapter headings would be chapter one
Foo and then in the next file it would just be one dot space Foo and then in the next file there
would be no chapter numbers at all it would just be Foo you know and and then maybe in the next
file it would be chapter one hard to carriage return Foo so there was no predictability about what
I was going to see in one text file to the next and that meant that there was no way to script some
kind of process to say hey when you see the word chapter make that whole line and H1 elements
or whatever and then when you see I don't know something else do something else with it you
know you could not do that it was not scriptable because no file was the same so when I found out
about will certainly doc book but but even even later when I found out about markdown and stuff
and kind of realized that it was imposing a kind of an agreement on how we were going to format
things then I realized the true power of of structure of of giving your data some kind of
predictable scriptable structure where we can say yes we know exactly what we're going to expect
in this data file because we've been told it is a book so we know that there will be headings
and we know that there will be sections and we will know that there will be URLs at some points
and maybe places to drop in images by our processor all that kind of thing all of that stuff becomes
very very predictable and you can reproduce the same set of processes across several several
several different files that's the power of structure and it's why you should be using
markdown restructured text asky doc and frankly probably doc book that's all for me about
doc book folks thanks for listening I hope you found it interesting and you should try doc book
out it's really quite quite cool it's a lot of fun and once you start getting into styling it
with XSL it's just super super satisfying and you know what best part about it it'll keep you out
of those word processors that's what I really care about talk to you next time
