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")
|
||||
|
||||
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.
