/*

** upb::json::Parser (upb_json_parser)
|
|
|
|
**
|
|
|
|
** A parser that uses the Ragel State Machine Compiler to generate
|
|
|
|
** the finite automata.
|
|
|
|
**
|
|
|
|
** Ragel only natively handles regular languages, but we can manually
|
|
|
|
** program it a bit to handle context-free languages like JSON, by using
|
|
|
|
** the "fcall" and "fret" constructs.
|
|
|
|
**
|
|
|
|
** This parser can handle the basics, but needs several things to be fleshed
|
|
|
|
** out:
|
|
|
|
**
|
|
|
|
** - handling of unicode escape sequences (including high surrogate pairs).
|
|
|
|
** - properly check and report errors for unknown fields, stack overflow,
|
|
|
|
** improper array nesting (or lack of nesting).
|
|
|
|
** - handling of base64 sequences with padding characters.
|
|
|
|
** - handling of push-back (non-success returns from sink functions).
|
|
|
|
** - handling of keys/escape-sequences/etc that span input buffers.

|
|
|
|
* example, to look up a member name in a hash table, or to turn a string into
|
|
|
|
* a number, the relevant library routines need the input string to be in

|
|
|
|
*
|
|
|
|
* In the common case we can just point to the input buffer to get this
|
|
|
|
* contiguous string and avoid any actual copy. So we optimistically begin
|
|
|
|
* this way. But there are a few cases where we must instead copy into a
|
|
|
|
* separate buffer:
|
|
|
|
*
|
|
|
|
* 1. The string was not contiguous in the input (it spanned buffers).
|
|
|
|
*
|
|
|
|
* 2. The string included escape sequences that need to be interpreted to get
|
|

/* The actual parser **********************************************************/

/* What follows is the Ragel parser itself. The language is specified in Ragel
|
|
|
|
* and the actions call our C functions above.
|
|
|
|
*
|
|
|
|
* Ragel has an extensive set of functionality, and we use only a small part of
|
|
|
|
* it. There are many action types but we only use a few:
|
|
|
|
*
|
|
|
|
* ">" -- transition into a machine
|
|
|
|
* "%" -- transition out of a machine
|
|
|
|
* "@" -- transition into a final state of a machine.
|
|
|
|
*
|
|
|
|
* "@" transitions are tricky because a machine can transition into a final
|
|
|
|
* state repeatedly. But in some cases we know this can't happen, for example
|
|
|
|
* a string which is delimited by a final '"' can only transition into its
|
|
|
|
* final state once, when the closing '"' is seen. */
