| <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 | |||
