1# UNK I/index.lh \ No newline at end of file

3## a very small static site generator
4
5**UNK** is an experiment in minimalism.
6It is a templating static site generator
7with an included markup language
8that all fits with 1000 bytes.
9There are three main scripts:
10
11- **UNK**, a bash script that applies the template
12 to each page and publishes them to the output dir,
13- **LHT**, an awk script that serves as a (very) basic
14 markup language, and
15- **TM**, the default template script for **UNK**.
16
17**UNK** and **LHT** are 250 bytes each, for a total of 500 bytes.
18**TM** takes up the remaining 500 bytes
19of the target 1000 bytes.
20You are, of course, free to make the template file as large
21and involved as you like.
22
23# DETAILS
24
25## unk
26
27**UNK** takes a set of files in a directory, applies a template to them,
28and output them into another directory as HTML files ready for a server.
29To keep a very small size, **UNK** delegates most file processing to **TM**,
30the main template. It delegates by using an idea found in
31[shab](https://github.com/zimbatm/shab):
32each input file is read as a `heredoc`, which enables
33shell interpolation.
34So the template, as opposed to the engine,
35can do all the heavy-lifting of index generation and navigation and such.
36
37Content goes into the following (hard-coded) directories:
38
39- **I/**, for written (*__i__nput*) content (the pages of the site),
40- **S/**, for ***s***tatic content (css, images, etc.), &
41- **O/**, for the (*__o__utput*) website, ready for `rsync`ing
42 to a server.
43
44If there is no **TM** in the directory where **UNK** is run,
45one will be created that will simply `cat` the file being processed.
46
47The following variables are made available to **TM**:
48
49- **FN**: the *FileName* (with directories removed)
50 of the file being processed
51- **TT**: the *TiTle* (the first line) of the file
52- **BD**: the *BoDy* (the rest) of the file
53
54as well as this function:
55
56- **X**, for *eXpand*: the `shab` stand-in.
57 It is much simpler than `shab`, and will fail if the template
58 (or if it nests templates, one of the nested ones)
59 has a `ZZ` on a line by itself, due to its `heredoc` nature.
60
61and these aliases (though they're more an artefact of saving space
62in the script, but they can be used in templates):
63
64- **c**: `cat`
65- **q**: `test`
66- **e**: `echo`
67
68As mentioned above, templates can be nested.
69Simply call another template from **TM** with the **X** function.
70
71## lht
72
73**LHT** stands for *Less HyperText*,
74because that's what you're writing when you're writing it
75(though not much less than HTML).
76Basically,
77blank lines are interpreted as `<p>` tag breaks,
78unless the previous source paragraph started with `<` and ended with `>`.
79It also has support for three inline spans:
80
81- `*em*` or `_em_` as *em*
82- `**strong**` or `__strong__` as **strong**
83- `` `code` `` as `code`.
84
85Everything else is just HTML.
86
87**LHT** was inspired, in part, by
88[Writing HTML in HTML](http://john.ankarstrom.se/html) by John Ankarstrom,
89as well as some other articles I can't think of right now.
90I liked the idea, but some tags in HTML are just annoying to write
91over and over, and take me out of the flow of writing prose.
92So I fixed those few tags.
93**The inline tags are definitely subject to change.**
94
95# Why?
96
97I was bored and decided I'd try to write a static site generator
98that could fit in a [toot] (500 characters).
99I [wrote][1] [a few][2] [of them][3],
100making them smaller and smaller each time.
101By the end, I was left with a *tiny* script
102that delegated almost *all* the work to the template file.
103That script became **UNK** in this repo.

109
110I was feeling pretty high on my horse after writing the tiny SSG,
111so I thought,
112*[maybe I could try for a tootable Markdown converter next][4]* --
113boy, was I wrong about that.
114Markdown is *way* too complicated to fit in 500 bytes.
115So I just wrote the Really Important Parts: `<p>` and some inlines.

129## Why this license?
130
131I was going to go with a stricter license like the GPL,
132but realized that
133
1341. this software isn't so important or time-consuming that I need
135 others to credit me or redistribute the project under the same terms, and
1362. the GPL is *way* too long for a project like this.
137 It's over 35 times *bigger* than the entirety of this project,
138 not counting the content or this README.
139 It would weigh down the entire undertaking.
140 The WTFPL, by contrast, is a trim 443 characters,
141 which is right in keeping with the smallness of this project.
