dkjson is a module for encoding and decoding JSON data. It supports UTF-8.

|
|

JSON (JavaScript Object Notation) is a format for serializing data based
|

|
on the syntax for JavaScript data structures.
|

dkjson is written in Lua without any dependencies, but

when LPeg is available dkjson uses it to speed up decoding.

David Kolf's JSON module for Lua 5.1/5.2
|
David Kolf's JSON module for Lua 5.1/5.2
|
||||||
========================================
|
|
||||||
|
|
||||||
*Version 2.4*
|
Version 2.5
|
||||||
|
|
||||||
In the default configuration this module writes no global values, not even
|
|
||||||
the module table. Import it using
|
|
||||||
|
|
||||||
json = require ("dkjson")
|
For the documentation see the corresponding readme.txt or visit
|
||||||
|
<http://dkolf.de/src/dkjson-lua.fsl/>.
|
||||||
In environments where `require` or a similiar function are not available
|
|
||||||
and you cannot receive the return value of the module, you can set the
|
|
||||||
option `register_global_module_table` to `true`. The module table will
|
|
||||||
then be saved in the global variable with the name given by the option
|
|
||||||
`global_module_name`.
|
|
||||||
|
|
||||||
Exported functions and values:
|
|
||||||
|
|
||||||
`json.encode (object [, state])`
|
|
||||||
--------------------------------
|
|
||||||
|
|
||||||
Create a string representing the object. `Object` can be a table,
|
|
||||||
a string, a number, a boolean, `nil`, `json.null` or any object with
|
|
||||||
a function `__tojson` in its metatable. A table can only use strings
|
|
||||||
and numbers as keys and its values have to be valid objects as
|
|
||||||
well. It raises an error for any invalid data types or reference
|
|
||||||
cycles.
|
|
||||||
|
|
||||||
`state` is an optional table with the following fields:
|
|
||||||
|
|
||||||
- `indent`
|
|
||||||
When `indent` (a boolean) is set, the created string will contain
|
|
||||||
newlines and indentations. Otherwise it will be one long line.
|
|
||||||
- `keyorder`
|
|
||||||
`keyorder` is an array to specify the ordering of keys in the
|
|
||||||
encoded output. If an object has keys which are not in this array
|
|
||||||
they are written after the sorted keys.
|
|
||||||
- `level`
|
|
||||||
This is the initial level of indentation used when `indent` is
|
|
||||||
set. For each level two spaces are added. When absent it is set
|
|
||||||
to 0.
|
|
||||||
- `buffer`
|
|
||||||
`buffer` is an array to store the strings for the result so they
|
|
||||||
can be concatenated at once. When it isn't given, the encode
|
|
||||||
function will create it temporary and will return the
|
|
||||||
concatenated result.
|
|
||||||
- `bufferlen`
|
|
||||||
When `bufferlen` is set, it has to be the index of the last
|
|
||||||
element of `buffer`.
|
|
||||||
- `tables`
|
|
||||||
`tables` is a set to detect reference cycles. It is created
|
|
||||||
temporary when absent. Every table that is currently processed
|
|
||||||
is used as key, the value is `true`.
|
|
||||||
|
|
||||||
When `state.buffer` was set, the return value will be `true` on
|
|
||||||
success. Without `state.buffer` the return value will be a string.
|
|
||||||
|
|
||||||
`json.decode (string [, position [, null]])`
|
|
||||||
--------------------------------------------
|
|
||||||
|
|
||||||
Decode `string` starting at `position` or at 1 if `position` was
|
|
||||||
omitted.
|
|
||||||
|
|
||||||
`null` is an optional value to be returned for null values. The
|
|
||||||
default is `nil`, but you could set it to `json.null` or any other
|
|
||||||
value.
|
|
||||||
|
|
||||||
The return values are the object or `nil`, the position of the next
|
|
||||||
character that doesn't belong to the object, and in case of errors
|
|
||||||
an error message.
|
|
||||||
|
|
||||||
Two metatables are created. Every array or object that is decoded gets
|
|
||||||
a metatable with the `__jsontype` field set to either `array` or
|
|
||||||
`object`. If you want to provide your own metatables use the syntax
|
|
||||||
|
|
||||||
json.decode (string, position, null, objectmeta, arraymeta)
|
|
||||||
|
|
||||||
To prevent the assigning of metatables pass `nil`:
|
|
||||||
|
|
||||||
json.decode (string, position, null, nil)
|
|
||||||
|
|
||||||
`<metatable>.__jsonorder`
|
|
||||||
-------------------------
|
|
||||||
|
|
||||||
`__jsonorder` can overwrite the `keyorder` for a specific table.
|
|
||||||
|
|
||||||
`<metatable>.__jsontype`
|
|
||||||
------------------------
|
|
||||||
|
|
||||||
`__jsontype` can be either `"array"` or `"object"`. This value is only
|
|
||||||
checked for empty tables. (The default for empty tables is `"array"`).
|
|
||||||
|
|
||||||
`<metatable>.__tojson (self, state)`
|
|
||||||
------------------------------------
|
|
||||||
|
|
||||||
You can provide your own `__tojson` function in a metatable. In this
|
|
||||||
function you can either add directly to the buffer and return true,
|
|
||||||
or you can return a string. On errors nil and a message should be
|
|
||||||
returned.
|
|
||||||
|
|
||||||
`json.null`
|
|
||||||
-----------
|
|
||||||
|
|
||||||
You can use this value for setting explicit `null` values.
|
|
||||||
|
|
||||||
`json.version`
|
|
||||||
--------------
|
|
||||||
|
|
||||||
Set to `"dkjson 2.4"`.
|
|
||||||
|
|
||||||
`json.quotestring (string)`
|
|
||||||
---------------------------
|
|
||||||
|
|
||||||
Quote a UTF-8 string and escape critical characters using JSON
|
|
||||||
escape sequences. This function is only necessary when you build
|
|
||||||
your own `__tojson` functions.
|
|
||||||
|
|
||||||
`json.addnewline (state)`
|
|
||||||
-------------------------
|
|
||||||
|
|
||||||
When `state.indent` is set, add a newline to `state.buffer` and spaces
|
|
||||||
according to `state.level`.
|
|
||||||
|
|
||||||
LPeg support
|
|
||||||
------------
|
|
||||||
|
|
||||||
When the local configuration variable `always_try_using_lpeg` is set,
|
|
||||||
this module tries to load LPeg to replace the `decode` function. The
|
|
||||||
speed increase is significant. You can get the LPeg module at
|
|
||||||
<http://www.inf.puc-rio.br/~roberto/lpeg/>.
|
|
||||||
When LPeg couldn't be loaded, the pure Lua functions stay active.
|
|
||||||
|
|
||||||
In case you don't want this module to require LPeg on its own,
|
|
||||||
disable the option `always_try_using_lpeg` in the options section at
|
|
||||||
the top of the module.
|
|
||||||
|
|
||||||
In this case you can later load LPeg support using
|
|
||||||
|
|
||||||
### `json.use_lpeg ()`
|
|
||||||
|
|
||||||
Require the LPeg module and replace the functions `quotestring` and
|
|
||||||
and `decode` with functions that use LPeg patterns.
|
|
||||||
This function returns the module table, so you can load the module
|
|
||||||
using:
|
|
||||||
|
|
||||||
json = require "dkjson".use_lpeg()
|
|
||||||
|
|
||||||
Alternatively you can use `pcall` so the JSON module still works when
|
|
||||||
LPeg isn't found.
|
|
||||||
|
|
||||||
json = require "dkjson"
|
|
||||||
pcall (json.use_lpeg)
|
|
||||||
|
|
||||||
### `json.using_lpeg`
|
|
||||||
|
|
||||||
This variable is set to `true` when LPeg was loaded successfully.

David Kolf's JSON module for Lua 5.1/5.2
|
||||||
|
========================================
|
||||||
|
|
||||||
|
*Version 2.5*
|
||||||
|
|
||||||
|
In the default configuration this module writes no global values, not even
|
||||||
|
the module table. Import it using
|
||||||
|
|
||||||
|
json = require ("dkjson")
|
||||||
|
|
||||||
|
In environments where `require` or a similiar function are not available
|
||||||
|
and you cannot receive the return value of the module, you can set the
|
||||||
|
option `register_global_module_table` to `true`. The module table will
|
||||||
|
then be saved in the global variable with the name given by the option
|
||||||
|
`global_module_name`.
|
||||||
|
|
||||||
|
Exported functions and values:
|
||||||
|
|
||||||
|
`json.encode (object [, state])`
|
||||||
|
--------------------------------
|
||||||
|
|
||||||
|
Create a string representing the object. `Object` can be a table,
|
||||||
|
a string, a number, a boolean, `nil`, `json.null` or any object with
|
||||||
|
a function `__tojson` in its metatable. A table can only use strings
|
||||||
|
and numbers as keys and its values have to be valid objects as
|
||||||
|
well. It raises an error for any invalid data types or reference
|
||||||
|
cycles.
|
||||||
|
|
||||||
|
`state` is an optional table with the following fields:
|
||||||
|
|
||||||
|
- `indent`
|
||||||
|
When `indent` (a boolean) is set, the created string will contain
|
||||||
|
newlines and indentations. Otherwise it will be one long line.
|
||||||
|
- `keyorder`
|
||||||
|
`keyorder` is an array to specify the ordering of keys in the
|
||||||
|
encoded output. If an object has keys which are not in this array
|
||||||
|
they are written after the sorted keys.
|
||||||
|
- `level`
|
||||||
|
This is the initial level of indentation used when `indent` is
|
||||||
|
set. For each level two spaces are added. When absent it is set
|
||||||
|
to 0.
|
||||||
|
- `buffer`
|
||||||
|
`buffer` is an array to store the strings for the result so they
|
||||||
|
can be concatenated at once. When it isn't given, the encode
|
||||||
|
function will create it temporary and will return the
|
||||||
|
concatenated result.
|
||||||
|
- `bufferlen`
|
||||||
|
When `bufferlen` is set, it has to be the index of the last
|
||||||
|
element of `buffer`.
|
||||||
|
- `tables`
|
||||||
|
`tables` is a set to detect reference cycles. It is created
|
||||||
|
temporary when absent. Every table that is currently processed
|
||||||
|
is used as key, the value is `true`.
|
||||||
|
- `exception`
|
||||||
|
When `exception` is given, it will be called whenever the encoder
|
||||||
|
cannot encode a given value.
|
||||||
|
The parameters are `reason`, `value`, `state` and `defaultmessage`.
|
||||||
|
`reason` is either `"reference cycle"`, `"custom encoder failed"` or
|
||||||
|
`"unsupported type"`. `value` is the original value that caused the
|
||||||
|
exception, `state` is this state table, `defaultmessage` is the message
|
||||||
|
of the error that would usually be raised.
|
||||||
|
You can either return `true` and add directly to the buffer or you can
|
||||||
|
return the string directly. To keep raising an error return `nil` and
|
||||||
|
the desired error message.
|
||||||
|
An example implementation for an exception function is given in
|
||||||
|
`json.encodeexception`.
|
||||||
|
|
||||||
|
When `state.buffer` was set, the return value will be `true` on
|
||||||
|
success. Without `state.buffer` the return value will be a string.
|
||||||
|
|
||||||
|
`json.decode (string [, position [, null]])`
|
||||||
|
--------------------------------------------
|
||||||
|
|
||||||
|
Decode `string` starting at `position` or at 1 if `position` was
|
||||||
|
omitted.
|
||||||
|
|
||||||
|
`null` is an optional value to be returned for null values. The
|
||||||
|
default is `nil`, but you could set it to `json.null` or any other
|
||||||
|
value.
|
||||||
|
|
||||||
|
The return values are the object or `nil`, the position of the next
|
||||||
|
character that doesn't belong to the object, and in case of errors
|
||||||
|
an error message.
|
||||||
|
|
||||||
|
Two metatables are created. Every array or object that is decoded gets
|
||||||
|
a metatable with the `__jsontype` field set to either `array` or
|
||||||
|
`object`. If you want to provide your own metatables use the syntax
|
||||||
|
|
||||||
|
json.decode (string, position, null, objectmeta, arraymeta)
|
||||||
|
|
||||||
|
To prevent the assigning of metatables pass `nil`:
|
||||||
|
|
||||||
|
json.decode (string, position, null, nil)
|
||||||
|
|
||||||
|
`<metatable>.__jsonorder`
|
||||||
|
-------------------------
|
||||||
|
|
||||||
|
`__jsonorder` can overwrite the `keyorder` for a specific table.
|
||||||
|
|
||||||
|
`<metatable>.__jsontype`
|
||||||
|
------------------------
|
||||||
|
|
||||||
|
`__jsontype` can be either `"array"` or `"object"`. This value is only
|
||||||
|
checked for empty tables. (The default for empty tables is `"array"`).
|
||||||
|
|
||||||
|
`<metatable>.__tojson (self, state)`
|
||||||
|
------------------------------------
|
||||||
|
|
||||||
|
You can provide your own `__tojson` function in a metatable. In this
|
||||||
|
function you can either add directly to the buffer and return true,
|
||||||
|
or you can return a string. On errors nil and a message should be
|
||||||
|
returned.
|
||||||
|
|
||||||
|
`json.null`
|
||||||
|
-----------
|
||||||
|
|
||||||
|
You can use this value for setting explicit `null` values.
|
||||||
|
|
||||||
|
`json.version`
|
||||||
|
--------------
|
||||||
|
|
||||||
|
Set to `"dkjson 2.5"`.
|
||||||
|
|
||||||
|
`json.quotestring (string)`
|
||||||
|
---------------------------
|
||||||
|
|
||||||
|
Quote a UTF-8 string and escape critical characters using JSON
|
||||||
|
escape sequences. This function is only necessary when you build
|
||||||
|
your own `__tojson` functions.
|
||||||
|
|
||||||
|
`json.addnewline (state)`
|
||||||
|
-------------------------
|
||||||
|
|
||||||
|
When `state.indent` is set, add a newline to `state.buffer` and spaces
|
||||||
|
according to `state.level`.
|
||||||
|
|
||||||
|
`json.encodeexception (reason, value, state, defaultmessage)`
|
||||||
|
-------------------------------------------------------------
|
||||||
|
|
||||||
|
This function can be used as value to the `exception` option. Instead of
|
||||||
|
raising an error this function encodes the error message as a string. This
|
||||||
|
can help to debug malformed input data.
|
||||||
|
|
||||||
|
x = json.encode(value, { exception = json.encodeexception })
|
||||||
|
|
||||||
|
LPeg support
|
||||||
|
------------
|
||||||
|
|
||||||
|
When the local configuration variable `always_try_using_lpeg` is set,
|
||||||
|
this module tries to load LPeg to replace the `decode` function. The
|
||||||
|
speed increase is significant. You can get the LPeg module at
|
||||||
|
<http://www.inf.puc-rio.br/~roberto/lpeg/>.
|
||||||
|
When LPeg couldn't be loaded, the pure Lua functions stay active.
|
||||||
|
|
||||||
|
In case you don't want this module to require LPeg on its own,
|
||||||
|
disable the option `always_try_using_lpeg` in the options section at
|
||||||
|
the top of the module.
|
||||||
|
|
||||||
|
In this case you can later load LPeg support using
|
||||||
|
|
||||||
|
### `json.use_lpeg ()`
|
||||||
|
|
||||||
|
Require the LPeg module and replace the functions `quotestring` and
|
||||||
|
and `decode` with functions that use LPeg patterns.
|
||||||
|
This function returns the module table, so you can load the module
|
||||||
|
using:
|
||||||
|
|
||||||
|
json = require "dkjson".use_lpeg()
|
||||||
|
|
||||||
|
Alternatively you can use `pcall` so the JSON module still works when
|
||||||
|
LPeg isn't found.
|
||||||
|
|
||||||
|
json = require "dkjson"
|
||||||
|
pcall (json.use_lpeg)
|
||||||
|
|
||||||
|
### `json.using_lpeg`
|
||||||
|
|
||||||
|
This variable is set to `true` when LPeg was loaded successfully.
