<h1>The h Programming Language</h1>
<p><big>A simple, fast, open-source, complete and safe language for developing modern software for the web</big></p>
<hr />
<h2>Example Program</h2>
<code><pre>h</pre></code>
<p>Outputs:</p>
<code><pre>h</pre></code>
<hr />
<h2>Fast Compilation</h2>
<p>h compiles hundreds of characters of source per second. I didn't really test how fast it is, but when I was testing it the speed was fast enough that I didn't care to profile it.</p>
<hr />
<h2>Safety</h2>
<p>h is completely memory safe with no garbage collector or heap allocations. It does not allow memory leaks to happen, nor do any programs in h have the possibility to allocate memory.</p>
<ul>
<li>No null</li>
<li>Completely deterministic behavior</li>
<li>No mutable state</li>
<li>No persistence</li>
<li>All functions are pure functions</li>
<li>No sandboxing required</li>
</ul>
<hr />
<h2>Zero* Dependencies</h2>
<p>h generates <a href="http://webassembly.org">WebAssembly</a>, so every binary produced by the compiler is completely dependency free save a single system call: <code>h.h</code>. This allows for modern, future-proof code that will work on all platforms.</p>
<hr />
<h2>Simple</h2>
<p>h has a <a href="https://github.com/Xe/x/blob/master/h/h.peg">simple grammar</a> that gzips to 117 bytes. Creating a runtime environment for h is so trivial just about anyone can do it.</p>
<hr />
<h2>Platform Support</h2>
<p>h supports the following platforms:</p>
<ul>
<li>Google Chrome</li>
<li>Electron</li>
<li>Chromium Embedded Framework</li>
<li>Microsoft Edge</li>
<li>Olin</li>
</ul>
<hr />
<h2>International Out of the Box</h2>
<p>h supports multiple written and spoken languages with true contextual awareness. It not only supports the Latin <code>h</code> as input, it also accepts the <a href="http://lojban.org">Lojbanic</a> <code>'</code> as well. This allows for full 100% internationalization into Lojban should your project needs require it.</p>
<hr />
<h2>Testimonials</h2>
<p>Not convinced? Take the word of people we probably didn't pay for their opinion.</p>
<ul>
<li>I don't see the point of this.</li>
<li>This solves all my problems. All of them. Just not in the way I expected it to.</li>
<li>Yes.</li>
<li>Perfect.</li>
<li>h is the backbone of my startup.</li>
</ul>
<hr />
<h2>Open-Source</h2>
<p>The h compiler and default runtime are <a href="https://github.com/Xe/x/tree/master/cmd/h">open-source</a> free software sent out into the <a href="https://creativecommons.org/choose/zero/">Public Domain</a>. You can use h for any purpose at all with no limitations or restrictions.</p>

<h1>Frequently Asked Questions</h1>
<h2>What are the instructions of h?</h2>
<p>h supports the following instructions:</p>
<ul>
<li><code>h</code></li>
<li><code>'</code></li>
</ul>
<p>All valid h instructions must be separated by a space (<code>\0x20</code> or the spacebar on your computer). No other forms of whitespace are permitted. Any other characters will render your program <a href="http://jbovlaste.lojban.org/dict/gentoldra">gentoldra</a>.</p>
<h2>How do I install and use h?</h2>
<p>With any computer running <a href="https://golang.org">Go</a> 1.11 or higher:</p>
<code><pre>go get -u -v within.website/x/cmd/h</pre></code>
Usage is simple:
<code><pre>Usage of h:
-config string
configuration file, if set (see flagconfyg(4))
-koan
if true, print the h koan and then exit
-license
show software licenses?
-manpage
generate a manpage template?
-max-playground-bytes int
how many bytes of data should users be allowed to
post to the playground? (default 75)
-o string
if specified, write the webassembly binary created
by -p here
-o-wat string
if specified, write the uncompiled webassembly
created by -p here
-p string
h program to compile/run
-port string
HTTP port to listen on
-v if true, print the version of h and then exit</pre></code>
<h2>What version is h?</h2>
<p>Version 1.0, this will hopefully be the only release.</p>
<h2>What is the h koan?</h2>
<p>And Jesus said unto the theologians, "Who do you say that I am?"</p>
<p>They replied: "You are the eschatological manifestation of the ground of our being, the kerygma of which we find the ultimate meaning in our interpersonal relationships."</p>
<p>And Jesus said "...What?"</p>
<p>Some time passed and one of them spoke "h".</p>
<p>Jesus was enlightened.</p>
<h2>Why?</h2>
<p>That's a good question. The following blogposts may help you understand this more:</p>
<ul>
<li><a href="https://christine.website/blog/the-origin-of-h-2015-12-14">The Origin of h</a></li>
<li><a href="https://christine.website/blog/formal-grammar-of-h-2019-05-19">A Formal Grammar of h</a></li>
</ul>
<h2>Who wrote h?</h2>
<p><a href="https://christine.website">Within</a></p>
