+# This file describes all Blink IDL extended attributes and allowed values.
+# If any IDL file uses an extended attribute or values not listed below, the
+# build will fail.
+# If you would like to add a new extended attribute or value, please:
+#     (1) add the extended attribute or value to this file
+#     (2) add an explanation to the Blink IDL extended attributes document:
+#         http://www.chromium.org/blink/webidl/blink-idl-extended-attributes
+#     (3) add appropriate test cases to run-bindings-tests
+#
+# The syntax of this file is as follows:
+#     - One extended attribute per one line: Name and (optionally) Values.
+#     - "Attr" means that the Attr does not take a value, i.e. [Attr].
+#     - "Attr=X" means that Attr takes a required value, which must be X;
+#       i.e. [Attr=X].
+#     - "Attr=X|Y|Z" means that Attr takes a required value, and the valid
+#       values are X, Y, and Z, and combinations thereof;
+#       e.g. [Attr=X], [Attr=Y], [Attr=X|Z].
+#       The separator must be | or &, so [Attr=X&Z] is also valid; the
+#       separator makes a difference for Conditional, but otherwise is simply
+#       a style convention.
+#     - "Attr=|X|Y|Z" means that Attr takes an optional value, whose valid
+#       values (if present) are X, Y, and Z, and combinations thereof; e.g.
+#       [Attr], [Attr=X], [Attr=Y], [Attr=X|Z], [Attr=X|Y|Z], [Attr=X&Z].
+#       Note that including an empty value in the list, as in [Attr=X||Y],
+#       is NOT valid: the value is optional, but empty values are not allowed.
+#     - "Attr=*" means that Attr takes a required value, which can be
+#       arbitrary, and combinations thereof, e.g. [Attr=IndexedDB],
+#       [Attr=DeleteFunction], [Attr=X|Y].
+#     - "Attr=|*" means that Attr takes an optional value, which can be
+#       arbitrary, e.g. [Attr], [Attr=X].
+#     - "Attr=X|*" means that Attr takes an required value, which can be
+#       arbitrary, but that "X" is standard, e.g. [Attr=X], [Attr=Foo].

+"""Generate Blink C++ bindings (.h and .cpp files) for use by Dart:HTML.
+
+If run itself, caches Jinja templates (and creates dummy file for build,
+since cache filenames are unpredictable and opaque).
+
+This module is *not* concurrency-safe without care: bytecode caching creates
+a race condition on cache *write* (crashes if one process tries to read a
+partially-written cache). However, if you pre-cache the templates (by running
+the module itself), then you can parallelize compiling individual files, since
+cache *reading* is safe.

+# module is imported, and relative if executed directly.
+# If paths differ between pre-caching and individual file compilation, the cache
+# is regenerated, which causes a race condition and breaks concurrent build,

+"""Lexer for Blink IDL.
+
+The lexer uses the PLY (Python Lex-Yacc) library to build a tokenizer which
+understands the Blink dialect of Web IDL and produces a token stream suitable
+for the Blink IDL parser.
+
+Blink IDL is identical to Web IDL at the token level, but the base lexer
+does not discard comments. We need to override (and not include comments in
+the token stream), as otherwise comments must be explicitly included in the
+phrase grammar of the parser.
+
+FIXME: Change base lexer to discard comments, and simply used the base
+lexer, eliminating this separate lexer.

+    # The PLY framework builds the actual low-level parser by introspecting this

+    #
+    # Reference:
+    # http://www.dabeaz.com/ply/ply.html#ply_nn23
+    #
+    # Review of yacc:
+    # Yacc parses a token stream, internally producing a Concrete Syntax Tree
+    # (CST), where each node corresponds to a production rule in the grammar.
+    # At each node, it runs an action, which is usually "produce a node in the
+    # Abstract Syntax Tree (AST)" or "ignore this node" (for nodes in the CST
+    # that aren't included in the AST, since only needed for parsing).
+    #
+    # The rules use pseudo-variables; in PLY syntax:
+    # p[0] is the left side: assign return value to p[0] instead of returning,
+    # p[1] ... p[n] are the right side: the values can be accessed, and they
+    # can be modified.
+    # (In yacc these are $$ and $1 ... $n.)
+    #
+    # The rules can look cryptic at first, but there are a few standard
+    # transforms from the CST to AST. With these in mind, the actions should
+    # be reasonably legible.
+    #
+    # * Ignore production
+    #   Discard this branch. Primarily used when one alternative is empty.
+    #
+    #   Sample code:
+    #   if len(p) > 1:
+    #       p[0] = ...
+    #   # Note no assignment if len(p) == 1
+    #
+    # * Eliminate singleton production
+    #   Discard this node in the CST, pass the next level down up the tree.
+    #   Used to ignore productions only necessary for parsing, but not needed
+    #   in the AST.
+    #
+    #   Sample code:
+    #   p[0] = p[1]
+    #
+    # * Build node
+    #   The key type of rule. In this parser, produces object of class IDLNode.
+    #   There are several helper functions:
+    #   * BuildProduction: actually builds an IDLNode, based on a production.
+    #   * BuildAttribute: builds an IDLAttribute, which is a temporary
+    #                     object to hold a name-value pair, which is then
+    #                     set as a Property of the IDLNode when the IDLNode
+    #                     is built.
+    #   * BuildNamed: Same as BuildProduction, and sets the 'NAME' property.
+    #   * BuildTrue: BuildAttribute with value True, for flags.

+"""Compute global interface information, including public information, dependencies, and inheritance.
+
+Computed data is stored in a global variable, |interfaces_info|, and written as
+output (concretely, exported as a pickle). This is then used by the IDL compiler
+itself, so it does not need to compute global information itself, and so that
+inter-IDL dependencies are clear, since they are all computed here.
+
+The |interfaces_info| pickle is a *global* dependency: any changes cause a full
+rebuild. This is to avoid having to compute which public data is visible by
+which IDL files on a file-by-file basis, which is very complex for little
+benefit.
+|interfaces_info| should thus only contain data about an interface that
+contains paths or is needed by *other* interfaces, e.g., path data (to abstract
+the compiler from OS-specific file paths) or public data (to avoid having to
+read other interfaces unnecessarily).
+It should *not* contain full information about an interface (e.g., all
+extended attributes), as this would cause unnecessary rebuilds.
+
+|interfaces_info| is a dict, keyed by |interface_name|.
+
+Current keys are:
+* dependencies:
+    'implements_interfaces': targets of 'implements' statements
+    'referenced_interfaces': reference interfaces that are introspected
+                             (currently just targets of [PutForwards])
+
+* inheritance:
+    'ancestors': all ancestor interfaces
+    'inherited_extended_attributes': inherited extended attributes
+                                     (all controlling memory management)
+
+* public:
+    'is_callback_interface': bool, callback interface or not
+    'implemented_as': value of [ImplementedAs=...] on interface (C++ class name)
+
+* paths:
+    'full_path': path to the IDL file, so can lookup an IDL by interface name
+    'include_path': path for use in C++ #include directives
+    'dependencies_full_paths': paths to dependencies (for merging into main)
+    'dependencies_include_paths': paths for use in C++ #include directives
+
+Note that all of these are stable information, unlikely to change without
+moving or deleting files (hence requiring a full rebuild anyway) or significant
+code changes (for inherited extended attributes).
