<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> |
