+  * comments: this editor features display line wrap
+
+NOTE:
+
+[SiSU parses files with long lines or line breaks,
+but, display linewrap (without line-breaks) is a
+convenient editor feature to have for sisu markup]

+;;; Commentary:
+
+;; SiSU (https://www.sisudoc.org/) is a document structuring and
+;; publishing framework.  This package provides an Emacs major mode
+;; for SiSU markup, as used by the spine parser (in D) which has a different
+;; header (based on yaml) from the original sisu parser (in Ruby) which has
+;; bespoke headers.
+
+;; When this package is installed, files ending in ".sst" are automatically
+;; associated with sisu-spine-mode.  If a file doesn't have a
+;; .sst extension, add a first line:
+;; # -*- sisuSpine -*-
+
+;; The documentation for the "Structure Of The Hierarchy Text" can be
+;; found in the sisustring for the sisu-spine-mode function.

+
+	---
+	import arsd.cgi;
+
+	// Instead of writing your own main(), you should write a function
+	// that takes a Cgi param, and use mixin GenericMain
+	// for maximum compatibility with different web servers.
+	void hello(Cgi cgi) {
+		cgi.setResponseContentType("text/plain");
+
+		if("name" in cgi.get)
+			cgi.write("Hello, " ~ cgi.get["name"]);
+		else
+			cgi.write("Hello, world!");
+	}
+
+	mixin GenericMain!hello;
+	---
+
+	Test on console (works in any interface mode):
+	$(CONSOLE
+		$ ./cgi_hello GET / name=whatever
+	)
+
+	If using http version (default on `dub` builds, or on custom builds when passing `-version=embedded_httpd` to dmd):
+	$(CONSOLE
+		$ ./cgi_hello --port 8080
+		# now you can go to http://localhost:8080/?name=whatever
+	)
+
+
+	Compile_versions:
+
+	If you are using `dub`, use:
+
+	```sdlang
+	subConfiguration "arsd-official:cgi" "VALUE_HERE"
+	```
+
+	or to dub.json:
+
+	```json
+        	"subConfigurations": {"arsd-official:cgi": "VALUE_HERE"}
+	```
+
+	to change versions. The possible options for `VALUE_HERE` are:
+
+	$(LIST
+		* `embedded_httpd` for the embedded httpd version (built-in web server). This is the default.
+		* `cgi` for traditional cgi binaries.
+		* `fastcgi` for FastCGI builds.
+		* `scgi` for SCGI builds.
+	)
+
+	With dmd, use:
+
+	$(TABLE_ROWS
+
+		* + Interfaces
+		  + (mutually exclusive)
+
+		* - `-version=plain_cgi`
+			- The default building the module alone without dub - a traditional, plain CGI executable will be generated.
+		* - `-version=embedded_httpd`
+			- A HTTP server will be embedded in the generated executable. This is default when building with dub.
+		* - `-version=fastcgi`
+			- A FastCGI executable will be generated.
+		* - `-version=scgi`
+			- A SCGI (SimpleCGI) executable will be generated.
+
+		* - `-version=embedded_httpd_threads`
+			- The embedded HTTP server will use a single process with a thread pool. (use instead of plain `embedded_httpd` if you want this specific implementation)
+		* - `-version=embedded_httpd_processes`
+			- The embedded HTTP server will use a prefork style process pool. (use instead of plain `embedded_httpd` if you want this specific implementation)
+		* - `-version=embedded_httpd_processes_accept_after_fork`
+			- It will call accept() in each child process, after forking. This is currently the only option, though I am experimenting with other ideas. You probably should NOT specify this right now.
+
+		* + Tweaks
+		  + (can be used together with others)
+
+		* - `-version=cgi_with_websocket`
+			- The CGI class has websocket server support.
+
+		* - `-version=with_openssl`
+			- not currently used
+		* - `-version=cgi_embedded_sessions`
+			- The session server will be embedded in the cgi.d server process
+		* - `-version=cgi_session_server_process`
+			- The session will be provided in a separate process, provided by cgi.d.
+	)
+
+	Compile_and_run:
+	
+	For CGI, `dmd yourfile.d cgi.d` then put the executable in your cgi-bin directory.
+
+	For FastCGI: `dmd yourfile.d cgi.d -version=fastcgi` and run it. spawn-fcgi helps on nginx. You can put the file in the directory for Apache. On IIS, run it with a port on the command line (this causes it to call FCGX_OpenSocket, which can work on nginx too).
+
+	For SCGI: `dmd yourfile.d cgi.d -version=scgi` and run the executable, providing a port number on the command line.
+
+	For an embedded HTTP server, run `dmd yourfile.d cgi.d -version=embedded_httpd` and run the generated program. It listens on port 8085 by default. You can change this on the command line with the --port option when running your program.
+
+	You can also simulate a request by passing parameters on the command line, like:
+
+	$(CONSOLE
+	./yourprogram GET / name=adr
+	)
+
+	And it will print the result to stdout.
+
+	CGI_Setup_tips:
+
+	On Apache, you may do `SetHandler cgi-script` in your `.htaccess` file.
+
+	Integration_tips:
+
+	cgi.d works well with dom.d for generating html. You may also use web.d for other utilities and automatic api wrapping.
+
+	dom.d usage:
+
+	---
+		import arsd.cgi;
+		import arsd.dom;
+
+		void hello_dom(Cgi cgi) {
+			auto document = new Document();
+
+			static import std.file;
+			// parse the file in strict mode, requiring it to be well-formed UTF-8 XHTML
+			// (You'll appreciate this if you've ever had to deal with a missing </div>
+			// or something in a php or erb template before that would randomly mess up
+			// the output in your browser. Just check it and throw an exception early!)
+			//
+			// You could also hard-code a template or load one at compile time with an
+			// import expression, but you might appreciate making it a regular file
+			// because that means it can be more easily edited by the frontend team and
+			// they can see their changes without needing to recompile the program.
+			//
+			// Note on CTFE: if you do choose to load a static file at compile time,
+			// you *can* parse it in CTFE using enum, which will cause it to throw at
+			// compile time, which is kinda cool too. Be careful in modifying that document,
+			// though, as it will be a static instance. You might want to clone on on demand,
+			// or perhaps modify it lazily as you print it out. (Try element.tree, it returns
+			// a range of elements which you could send through std.algorithm functions. But
+			// since my selector implementation doesn't work on that level yet, you'll find that
+			// harder to use. Of course, you could make a static list of matching elements and
+			// then use a simple e is e2 predicate... :) )
+			document.parseUtf8(std.file.read("your_template.html"), true, true);
+
+			// fill in data using DOM functions, so placing it is in the hands of HTML
+			// and it will be properly encoded as text too.
+			//
+			// Plain html templates can't run server side logic, but I think that's a
+			// good thing - it keeps them simple. You may choose to extend the html,
+			// but I think it is best to try to stick to standard elements and fill them
+			// in with requested data with IDs or class names. A further benefit of
+			// this is the designer can also highlight data based on sources in the CSS.
+			//
+			// However, all of dom.d is available, so you can format your data however
+			// you like. You can do partial templates with innerHTML too, or perhaps better,
+			// injecting cloned nodes from a partial document.
+			//
+			// There's a lot of possibilities.
+			document["#name"].innerText = cgi.request("name", "default name");
+
+			// send the document to the browser. The second argument to `cgi.write`
+			// indicates that this is all the data at once, enabling a few small
+			// optimizations.
+			cgi.write(document.toString(), true);

+
+	Guide_for_PHP_users:
+		If you are coming from PHP, here's a quick guide to help you get started:
+
+		$(SIDE_BY_SIDE
+			$(COLUMN
+				```php
+				<?php
+					$foo = $_POST["foo"];
+					$bar = $_GET["bar"];
+					$baz = $_COOKIE["baz"];
+
+					$user_ip = $_SERVER["REMOTE_ADDR"];
+					$host = $_SERVER["HTTP_HOST"];
+					$path = $_SERVER["PATH_INFO"];
+
+					setcookie("baz", "some value");
+
+					echo "hello!";
+				?>
+				```
+			)
+			$(COLUMN
+				---
+				import arsd.cgi;
+				void app(Cgi cgi) {
+					string foo = cgi.post["foo"];
+					string bar = cgi.get["bar"];
+					string baz = cgi.cookies["baz"];
+
+					string user_ip = cgi.remoteAddress;
+					string host = cgi.host;
+					string path = cgi.pathInfo;
+
+					cgi.setCookie("baz", "some value");
+
+					cgi.write("hello!");
+				}
+
+				mixin GenericMain!app
+				---
+			)
+		)
+
+		$(H3 Array elements)
+
+
+		In PHP, you can give a form element a name like `"something[]"`, and then
+		`$_POST["something"]` gives an array. In D, you can use whatever name
+		you want, and access an array of values with the `cgi.getArray["name"]` and
+		`cgi.postArray["name"]` members.
+
+		$(H3 Databases)
+
+		PHP has a lot of stuff in its standard library. cgi.d doesn't include most
+		of these, but the rest of my arsd repository has much of it. For example,
+		to access a MySQL database, download `database.d` and `mysql.d` from my
+		github repo, and try this code (assuming, of course, your database is
+		set up):
+
+		---
+		import arsd.cgi;
+		import arsd.mysql;
+
+		void app(Cgi cgi) {
+			auto database = new MySql("localhost", "username", "password", "database_name");
+			foreach(row; mysql.query("SELECT count(id) FROM people"))
+				cgi.write(row[0] ~ " people in database");
+		}
+
+		mixin GenericMain!app;
+		---
+
+		Similar modules are available for PostgreSQL, Microsoft SQL Server, and SQLite databases,
+		implementing the same basic interface.
+
+	See_Also:
+
+	You may also want to see [arsd.dom], [arsd.web], and [arsd.html] for more code for making
+	web applications.
+
+	For working with json, try [arsd.jsvar].
+	
+	[arsd.database], [arsd.mysql], [arsd.postgres], [arsd.mssql], and [arsd.sqlite] can help in
+	accessing databases.
+
+	If you are looking to access a web application via HTTP, try [std.net.curl], [arsd.curl], or [arsd.http2].

+	import core.runtime;
+	auto args = Runtime.args();
+
+	we can call the app a few ways:
+
+	1) set up the environment variables and call the app (manually simulating CGI)
+	2) simulate a call automatically:
+		./app method 'uri'
+
+		for example:
+			./app get /path?arg arg2=something
+
+	  Anything on the uri is treated as query string etc
+
+	  on get method, further args are appended to the query string (encoded automatically)
+	  on post method, further args are done as post
+
+
+	  @name means import from file "name". if name == -, it uses stdin
+	  (so info=@- means set info to the value of stdin)
+
+
+	  Other arguments include:
+	  	--cookie name=value (these are all concated together)
+		--header 'X-Something: cool'
+		--referrer 'something'
+		--port 80
+		--remote-address some.ip.address.here
+		--https yes
+		--user-agent 'something'
+		--userpass 'user:pass'
+		--authorization 'Basic base64encoded_user:pass'
+		--accept 'content' // FIXME: better example
+		--last-event-id 'something'
+		--host 'something.com'
+
+	  Non-simulation arguments:
+	  	--port xxx listening port for non-cgi things (valid for the cgi interfaces)
+		--listening-host  the ip address the application should listen on, or if you want to use unix domain sockets, it is here you can set them: `--listening-host unix:filename` or, on Linux, `--listening-host abstract:name`.

+			For small files, cgi.d will buffer the uploaded file in memory, and make it

+
+			I find the file is very large, it is undesirable to eat that much memory just

+			to the constructor so they are accepted, cgi.d will write the content to a temporary
+			file that you can re-read later.
+
+			You can override this behavior by subclassing Cgi and overriding the protected
+			handlePostChunk method. Note that the object is not initialized when you
+			write that method - the http headers are available, but the cgi.post method
+			is not. You may parse the file as it streams in using this method.
+
+
+			Anyway, if the file is small enough to be in memory, contentInMemory will be
+			set to true, and the content is available in the content member.
+
+			If not, contentInMemory will be set to false, and the content saved in a file,
+			whose name will be available in the contentFilename member.
+
+
+			Tip: if you know you are always dealing with small files, and want the convenience
+			of ignoring this member, construct Cgi with a small maxContentLength. Then, if
+			a large file comes in, it simply throws an exception (and HTTP error response)
+			instead of trying to handle it.
+

+		just so TLS stuff doesn't randomly change in the middle. but I could
+		specify if you yield all bets are off.
+
+		when the request is finished, if there's more data buffered, it just
+		keeps going. if there is no more data buffered, it epoll ctls to 
+		get triggered when more data comes in. all one shot.
+
+		when a connection is closed, the fiber returns and is then reset
+		and added to the free list. if the free list is full, the fiber is
+		just freed, this means it will balloon to a certain size but not generally
+		grow beyond that unless the activity keeps going.
+
+		256 KB stack i thnk per fiber. 4,000 active fibers per gigabyte of memory.
+
+	So the fiber has its own magic methods to read and write. if they would block, it registers
+	for epoll and yields. when it returns, it read/writes and then returns back normal control.
+
+	basically you issue the command and it tells you when it is done
+
+	it needs to DEL the epoll thing when it is closed. add it when opened. mod it when anther thing issued

+import core.thread;
+/+
+	cgi.d now uses a hybrid of event i/o and threads at the top level.
+
+	Top level thread is responsible for accepting sockets and selecting on them.
+
+	It then indicates to a child that a request is pending, and any random worker
+	thread that is free handles it. It goes into blocking mode and handles that
+	http request to completion.
+
+	At that point, it goes back into the waiting queue.
+
+
+	This concept is only implemented on Linux. On all other systems, it still
+	uses the worker threads and semaphores (which is perfectly fine for a lot of
+	things! Just having a great number of keep-alive connections will break that.)
+
+
+	So the algorithm is:
+
+	select(accept, event, pending)
+		if accept -> send socket to free thread, if any. if not, add socket to queue
+		if event -> send the signaling thread a socket from the queue, if not, mark it free
+			- event might block until it can be *written* to. it is a fifo sending socket fds!
+
+	A worker only does one http request at a time, then signals its availability back to the boss.
+
+	The socket the worker was just doing should be added to the one-off epoll read. If it is closed,
+	great, we can get rid of it. Otherwise, it is considered `pending`. The *kernel* manages that; the
+	actual FD will not be kept out here.
+
+	So:
+		queue = sockets we know are ready to read now, but no worker thread is available
+		idle list = worker threads not doing anything else. they signal back and forth
+
+	the workers all read off the event fd. This is the semaphore wait
+
+	the boss waits on accept or other sockets read events (one off! and level triggered). If anything happens wrt ready read,
+	it puts it in the queue and writes to the event fd.
+
+	The child could put the socket back in the epoll thing itself.
+
+	The child needs to be able to gracefully handle being given a socket that just closed with no work.

+	Here's the way the RPC interface works:
+
+	You define the interface that lists the functions you can call on the remote process.
+	The interface may also have static methods for convenience. These forward to a singleton
+	instance of an auto-generated class, which actually sends the args over the pipe.
+
+	An impl class actually implements it. A receiving server deserializes down the pipe and
+	calls methods on the class.
+
+	I went with the interface to get some nice compiler checking and documentation stuff.
+
+	I could have skipped the interface and just implemented it all from the server class definition
+	itself, but then the usage may call the method instead of rpcing it; I just like having the user
+	interface and the implementation separate so you aren't tempted to `new impl` to call the methods.
+
+
+	I fiddled with newlines in the mixin string to ensure the assert line numbers matched up to the source code line number. Idk why dmd didn't do this automatically, but it was important to me.

+
+	But arrays and structs are a bit different. Arrays come from the cgi array. Thus
+	they are passed
+
+	arr=foo&arr=bar <-- notice the same name.
+
+	Structs are first declared with an empty thing, then have their members set individually,
+	with dot notation. The members are not required, just the initial declaration.
+
+	struct Foo {
+		int a;
+		string b;
+	}
+	void test(Foo foo){}
+
+	foo&foo.a=5&foo.b=str <-- the first foo declares the arg, the others set the members
+
+	Arrays of structs use this declaration.
+
+	void test(Foo[] foo) {}
+
+	foo&foo.a=5&foo.b=bar&foo&foo.a=9
+
+	You can use a hidden input field in HTML forms to achieve this. The value of the naked name
+	declaration is ignored.
+
+	Mind that order matters! The declaration MUST come first in the string.
+
+	Arrays of struct members follow this rule recursively.
+
+	struct Foo {
+		int[] a;
+	}
+
+	foo&foo.a=1&foo.a=2&foo&foo.a=1
+
+
+	Associative arrays are formatted with brackets, after a declaration, like structs:
+
+	foo&foo[key]=value&foo[other_key]=value
+
+
+	Note: for maximum compatibility with outside code, keep your types simple. Some libraries
+	do not support the strict ordering requirements to work with these struct protocols.
+
+	FIXME: also perhaps accept application/json to better work with outside trash.
+
+
+	Return values are also auto-formatted according to user-requested type:
+		for json, it loops over and converts.
+		for html, basic types are strings. Arrays are <ol>. Structs are <dl>. Arrays of structs are tables!

+	Serves a REST object, similar to a Ruby on Rails resource.
+
+	You put data members in your class. cgi.d will automatically make something out of those.
+
+	It will call your constructor with the ID from the URL. This may be null.
+	It will then populate the data members from the request.
+	It will then call a method, if present, telling what happened. You don't need to write these!
+	It finally returns a reply.
+
+	Your methods are passed a list of fields it actually set.
+
+	The URL mapping - despite my general skepticism of the wisdom - matches up with what most REST
+	APIs I have used seem to follow. (I REALLY want to put trailing slashes on it though. Works better
+	with relative linking. But meh.)
+
+	GET /items -> index. all values not set.
+	GET /items/id -> get. only ID will be set, other params ignored.
+	POST /items -> create. values set as given
+	PUT /items/id -> replace. values set as given
+		or POST /items/id with cgi.post["_method"] (thus urlencoded or multipart content-type) set to "PUT" to work around browser/html limitation
+		a GET with cgi.get["_method"] (in the url) set to "PUT" will render a form.
+	PATCH /items/id -> update. values set as given, list of changed fields passed
+		or POST /items/id with cgi.post["_method"] == "PATCH"
+	DELETE /items/id -> destroy. only ID guaranteed to be set
+		or POST /items/id with cgi.post["_method"] == "DELETE"
+
+	Following the stupid convention, there will never be a trailing slash here, and if it is there, it will
+	redirect you away from it.
+
+	API clients should set the `Accept` HTTP header to application/json or the cgi.get["_format"] = "json" var.
+
+	I will also let you change the default, if you must.
+
+	// One add-on is validation. You can issue a HTTP GET to a resource with _method = VALIDATE to check potential changes.
+
+	You can define sub-resources on your object inside the object. These sub-resources are also REST objects
+	that follow the same thing. They may be individual resources or collections themselves.
+
+	Your class is expected to have at least the following methods:
+
+	FIXME: i kinda wanna add a routes object to the initialize call
+
+	create
+		Create returns the new address on success, some code on failure.
+	show
+	index
+	update
+	remove
+
+	You will want to be able to customize the HTTP, HTML, and JSON returns but generally shouldn't have to - the defaults
+	should usually work. The returned JSON will include a field "href" on all returned objects along with "id". Or omething like that.
+
+	Usage of this function will add a dependency on [arsd.dom] and [arsd.jsvar].
+
+	NOT IMPLEMENTED
+
+
+	Really, a collection is a resource with a bunch of subresources.
+
+		GET /items
+			index because it is GET on the top resource
+
+		GET /items/foo
+			item but different than items?
+
+		class Items {
+
+		}
+
+	... but meh, a collection can be automated. not worth making it
+	a separate thing, let's look at a real example. Users has many
+	items and a virtual one, /users/current.
+
+	the individual users have properties and two sub-resources:
+	session, which is just one, and comments, a collection.
+
+	class User : RestObject!() { // no parent
+		int id;
+		string name;
+
+		// the default implementations of the urlId ones is to call load(that_id) then call the arg-less one.
+		// but you can override them to do it differently.
+
+		// any member which is of type RestObject can be linked automatically via href btw.
+
+		void show() {}
+		void show(string urlId) {} // automated! GET of this specific thing
+		void create() {} // POST on a parent collection - this is called from a collection class after the members are updated
+		void replace(string urlId) {} // this is the PUT; really, it just updates all fields.
+		void update(string urlId, string[] fieldList) {} // PATCH, it updates some fields.
+		void remove(string urlId) {} // DELETE
+
+		void load(string urlId) {} // the default implementation of show() populates the id, then
+
+		this() {}
+
+		mixin Subresource!Session;
+		mixin Subresource!Comment;
+	}
+
+	class Session : RestObject!() {
+		// the parent object may not be fully constructed/loaded
+		this(User parent) {}
+
+	}
+
+	class Comment : CollectionOf!Comment {
+		this(User parent) {}
+	}
+
+	class Users : CollectionOf!User {
+		// but you don't strictly need ANYTHING on a collection; it will just... collect. Implement the subobjects.
+		void index() {} // GET on this specific thing; just like show really, just different name for the different semantics.
+		User create() {} // You MAY implement this, but the default is to create a new object, populate it from args, and then call create() on the child

+
+1~ Summary
+
+To get you started, the first paragraph following a section or chapter heading.
+
+Spine / SiSU documents minimum requirements:
+
+_* a header containing document metadata that must at least contain the fields Title and Creator Author.
+
+_* text body, identified as starting by the A~ marker at the start of a line, followed  by at least one level 1~ section heading with the text that follows it.~{ the document provided here would be a valid Spine document, and this text contained within the tilde and curly braces delimiters would be the first footnote/endnote }~
+
+To generate this document to have html and epub output for example you would run:
+
+``` code
+spine --html --epub --output=/tmp/spine-sample-output %s
+```
+
+1~ Conclusion
+
+This sample pod is provided to get you started.
+
+Good luck and good speed.
