+# Opossum Web Browser
+
+Basic portable Web browser; only needs a Go compiler to compile, no C dependencies
+
+Supported features:
+
+- rudimentary CSS/HTML5 support, large parts like float/flex layout are just stub implementations
+- Server-side rendered websites
+- Images (pre-loaded all at once though)
+- TLS
+- experimental JS/DOM without AJAX can be activated (basically script tags are evaluated)
+
+# Install
+
+## Plan 9
+
+You can download a tarball with the binary at http://psilva.sdf.org/opossum-plan9-amd64.tgz
+
+To compile the source Go 1.15 is needed. Probably `$GOPROXY` should be set to `https://proxy.golang.org`
+
+```
+cd cmd/browse
+go run .
+```
+
+## macOS
+
+Requirements:
+
+- Go
+- Plan9Port
+
+```
+cd cmd/browse
+go run .
+```
+
+## TODO
+
+- load images on the fly
+- implement more parts of HTML5 and CSS
+- create a widget for div/span
+- clean up code, support webfs, snarf, file downloads
\ No newline at end of file

+ /*
+ * Attributes in the DOM are tricky:
+ *
+ * - there are the 8 basic get/set/has/removeAttribute{NS} methods+ *
+ * - but many HTML attributes are also 'reflected' through IDL
+ * attributes which means that they can be queried and set through
+ * regular properties of the element. There is just one attribute
+ * value, but two ways to get and set it.
+ *
+ * - Different HTML element types have different sets of reflected
+ attributes.
+ *
+ * - attributes can also be queried and set through the .attributes
+ * property of an element. This property behaves like an array of
+ * Attr objects. The value property of each Attr is writeable, so
+ * this is a third way to read and write attributes.
+ *
+ * - for efficiency, we really want to store attributes in some kind
+ * of name->attr map. But the attributes[] array is an array, not a
+ * map, which is kind of unnatural.
+ *
+ * - When using namespaces and prefixes, and mixing the NS methods
+ * with the non-NS methods, it is apparently actually possible for
+ * an attributes[] array to have more than one attribute with the
+ * same qualified name. And certain methods must operate on only
+ * the first attribute with such a name. So for these methods, an
+ * inefficient array-like data structure would be easier to
+ * implement.
+ *
+ * - The attributes[] array is live, not a snapshot, so changes to the
+ * attributes must be immediately visible through existing arrays.
+ *
+ * - When attributes are queried and set through IDL properties
+ * (instead of the get/setAttributes() method or the attributes[]
+ * array) they may be subject to type conversions, URL
+ * normalization, etc., so some extra processing is required in that
+ * case.
+ *
+ * - But access through IDL properties is probably the most common
+ * case, so we'd like that to be as fast as possible.
+ *
+ * - We can't just store attribute values in their parsed idl form,
+ * because setAttribute() has to return whatever string is passed to
+ * getAttribute even if it is not a legal, parseable value. So
+ * attribute values must be stored in unparsed string form.
+ *
+ * - We need to be able to send change notifications or mutation
+ * events of some sort to the renderer whenever an attribute value
+ * changes, regardless of the way in which it changes.
+ *
+ * - Some attributes, such as id and class affect other parts of the
+ * DOM API, like getElementById and getElementsByClassName and so
+ * for efficiency, we need to specially track changes to these
+ * special attributes.
+ *
+ * - Some attributes like class have different names (className) when
+ * reflected.
+ *
+ * - Attributes whose names begin with the string 'data-' are treated
+ specially.
+ *
+ * - Reflected attributes that have a boolean type in IDL have special
+ * behavior: setting them to false (in IDL) is the same as removing
+ * them with removeAttribute()
+ *
+ * - numeric attributes (like HTMLElement.tabIndex) can have default
+ * values that must be returned by the idl getter even if the
+ * content attribute does not exist. (The default tabIndex value
+ * actually varies based on the type of the element, so that is a
+ * tricky one).
+ *
+ * See
+ * http://www.whatwg.org/specs/web-apps/current-work/multipage/urls.html#reflect
+ * for rules on how attributes are reflected.

+/*
+ * This file contains an implementation of the HTML parsing algorithm.
+ * The algorithm and the implementation are complex because HTML
+ * explicitly defines how the parser should behave for all possible
+ * valid and invalid inputs.
+ *
+ * Usage:
+ *
+ * The file defines a single HTMLParser() function, which dom.js exposes
+ * publicly as document.implementation.mozHTMLParser(). This is a
+ * factory function, not a constructor.
+ *
+ * When you call document.implementation.mozHTMLParser(), it returns
+ * an object that has parse() and document() methods. To parse HTML text,
+ * pass the text (in one or more chunks) to the parse() method. When
+ * you've passed all the text (on the last chunk, or afterward) pass
+ * true as the second argument to parse() to tell the parser that there
+ * is no more coming. Call document() to get the document object that
+ * the parser is parsing into. You can call this at any time, before
+ * or after calling parse().
+ *
+ * The first argument to mozHTMLParser is the absolute URL of the document.
+ *
+ * The second argument is optional and is for internal use only. Pass an
+ * element as the fragmentContext to do innerHTML parsing for the
+ * element. To do innerHTML parsing on a document, pass null. Otherwise,
+ * omit the 2nd argument. See HTMLElement.innerHTML for an example. Note
+ * that if you pass a context element, the end() method will return an
+ * unwrapped document instead of a wrapped one.
+ *
+ * Implementation details:
+ *
+ * This is a long file of almost 7000 lines. It is structured as one
+ * big function nested within another big function. The outer
+ * function defines a bunch of constant data, utility functions
+ * that use that data, and a couple of classes used by the parser.
+ * The outer function also defines and returns the
+ * inner function. This inner function is the HTMLParser factory
+ * function that implements the parser and holds all the parser state
+ * as local variables. The HTMLParser function is quite big because
+ * it defines many nested functions that use those local variables.
+ *
+ * There are three tightly coupled parser stages: a scanner, a
+ * tokenizer and a tree builder. In a (possibly misguided) attempt at
+ * efficiency, the stages are not implemented as separate classes:
+ * everything shares state and is (mostly) implemented in imperative
+ * (rather than OO) style.
+ *
+ * The stages of the parser work like this: When the client code calls
+ * the parser's parse() method, the specified string is passed to
+ * scanChars(). The scanner loops through that string and passes characters
+ * (sometimes one at a time, sometimes in chunks) to the tokenizer stage.
+ * The tokenizer groups the characters into tokens: tags, endtags, runs
+ * of text, comments, doctype declarations, and the end-of-file (EOF)
+ * token. These tokens are then passed to the tree building stage via
+ * the insertToken() function. The tree building stage builds up the
+ * document tree.
+ *
+ * The tokenizer stage is a finite state machine. Each state is
+ * implemented as a function with a name that ends in "_state". The
+ * initial state is data_state(). The current tokenizer state is stored
+ * in the variable 'tokenizer'. Most state functions expect a single
+ * integer argument which represents a single UTF-16 codepoint. Some
+ * states want more characters and set a lookahead property on
+ * themselves. The scanChars() function in the scanner checks for this
+ * lookahead property. If it doesn't exist, then scanChars() just passes
+ * the next input character to the current tokenizer state function.
+ * Otherwise, scanChars() looks ahead (a given # of characters, or for a
+ * matching string, or for a matching regexp) and passes a string of
+ * characters to the current tokenizer state function.
+ *
+ * As a shortcut, certain states of the tokenizer use regular expressions
+ * to look ahead in the scanner's input buffer for runs of text, simple
+ * tags and attributes. For well-formed input, these shortcuts skip a
+ * lot of state transitions and speed things up a bit.
+ *
+ * When a tokenizer state function has consumed a complete token, it
+ * emits that token, by calling insertToken(), or by calling a utility
+ * function that itself calls insertToken(). These tokens are passed to
+ * the tree building stage, which is also a state machine. Like the
+ * tokenizer, the tree building states are implemented as functions, and
+ * these functions have names that end with _mode (because the HTML spec
+ * refers to them as insertion modes). The current insertion mode is held
+ * by the 'parser' variable. Each insertion mode function takes up to 4
+ * arguments. The first is a token type, represented by the constants
+ * TAG, ENDTAG, TEXT, COMMENT, DOCTYPE and EOF. The second argument is
+ * the value of the token: the text or comment data, or tagname or
+ * doctype. For tags, the 3rd argument is an array of attributes. For
+ * DOCTYPES it is the optional public id. For tags, the 4th argument is
+ * true if the tag is self-closing. For doctypes, the 4th argument is the
+ * optional system id.
+ *
+ * Search for "***" to find the major sub-divisions in the code.

+ *
+ * After mechanical conversion, it was further converted from

+ * faithful rendering of the HTML tokenization spec in
+ * JavaScript.
+ *
+ * It is not a goal of this tokenizer to detect or report
+ * parse errors.
+ *
+ * XXX The tokenizer is supposed to work with straight UTF32
+ * codepoints. But I don't think it has any dependencies on
+ * any character outside of the BMP so I think it is safe to
+ * pass it UTF16 characters. I don't think it will ever change
+ * state in the middle of a surrogate pair.
+ */
+
+ /*
+ * Each state is represented by a function. For most states, the
+ * scanner simply passes the next character (as an integer
+ * codepoint) to the current state function and automatically
+ * consumes the character. If the state function can't process
+ * the character it can call pushback() to push it back to the
+ * scanner.
+ *
+ * Some states require lookahead, though. If a state function has
+ * a lookahead property, then it is invoked differently. In this
+ * case, the scanner invokes the function with 3 arguments: 1) the
+ * next codepoint 2) a string of lookahead text 3) a boolean that
+ * is true if the lookahead goes all the way to the EOF. (XXX
+ * actually maybe this third is not necessary... the lookahead
+ * could just include \uFFFF?)
+ *
+ * If the lookahead property of a state function is an integer, it
+ * specifies the number of characters required. If it is a string,
+ * then the scanner will scan for that string and return all
+ * characters up to and including that sequence, or up to EOF. If
+ * the lookahead property is a regexp, then the scanner will match
+ * the regexp at the current point and return the matching string.
+ *
+ * States that require lookahead are responsible for explicitly
+ * consuming the characters they process. They do this by
+ * incrementing nextchar by the number of processed characters.
