parseJson

Asdf parseJson(Flag!"includingNewLine" includingNewLine = Yes.includingNewLine, Flag!"spaces" spaces = Yes.spaces, Chunks)(Chunks chunks, size_t initLength = 32)
if (is(ElementType!Chunks : const(ubyte)[]));

Parses json value

Parameters:

Chunks chunks	input range composed of elements type of const(ubyte)[]. chunks can use the same buffer for each chunk.
size_t initLength	initial output buffer length. Minimal value equals 32.

Returns:

ASDF value

Examples:

import std.range: chunks;
auto text = cast(const ubyte[])`true `;
auto ch = text.chunks(3);
assert(ch.parseJson(32).data == [1]);

parseJson

Asdf parseJson(Flag!"includingNewLine" includingNewLine = Yes.includingNewLine, Flag!"spaces" spaces = Yes.spaces, Flag!"assumeValid" assumeValid = No.assumeValid, Allocator)(in char[] str, Allocator allocator);

Asdf parseJson(Flag!"includingNewLine" includingNewLine = Yes.includingNewLine, Flag!"spaces" spaces = Yes.spaces, Flag!"assumeValid" assumeValid = No.assumeValid)(in char[] str);

Parses json value

Parameters:

char[] str	input string
Allocator allocator	(optional) memory allocator

Returns:

ASDF value

Examples:

assert(`{"ak": {"sub": "subval"} }`.parseJson["ak", "sub"] == "subval");

parseJsonByLine

auto parseJsonByLine(Flag!"spaces" spaces = Yes.spaces, Flag!"throwOnInvalidLines" throwOnInvalidLines = No.throwOnInvalidLines, Input)(Input input);

Parses JSON value in each line from a Range of buffers.

Parameters:

spaces	adds support for spaces beetwen json tokens. Default value is Yes.
throwOnInvalidLines	throws an AsdfException on invalid lines if Yes and ignore invalid lines if No. Default value is No.
Input input	input range composed of elements type of const(ubyte)[] or string / const(char)[]. chunks can use the same buffer for each chunk.

Returns:

Input range composed of ASDF values. Each value uses the same internal buffer.

Examples:

import asdf.jsonparser;
import std.range: chunks;
auto text = cast(const ubyte[])"\t true \r\r\n false\t";
auto values = text.chunks(3).parseJsonByLine;
assert(values.front.data == [1]);
values.popFront;
assert(values.front.data == [2]);
values.popFront;
assert(values.empty);

Examples:

import std.conv;
import std.algorithm : map;
import std.range : array;
string text =  "\t " ~ `{"key": "a"}` ~ "\r\r\n" ~ `{"key2": "b"}`;
auto values = text.parseJsonByLine();
assert( values.front["key"] == "a");
values.popFront;
assert( values.front["key2"] == "b");
values.popFront;
