nvyson v1.0.9
nvyson
- a simple json-like format
- nvlang use this structure to transfer shape+symbol
- its a little complicated than nvzson
- for test compile-cli-tool of nvlang, normally USELESS
valid chars:
LBC : {
RBC : }
LBK : [
RBK : ]
symbol : [a-z][a-z0-9]* AND "@"
can NOT begin with <digit>
"@" IS a place-holder
ws : all others are treated-as white-space // so caps-lock A-Z OR chinese-characters could be used AS comments
example:
#0 { k0 k1 k2 [@ {k4 k5} @] k6 k7 }
when parse-to-json IN js:
#0 will become :
{ // implicit _0
k0:1, // implicit _1
k1:2, // implicit _2
k2:3, // implicit _3
_4:[ // explicit _4 is auto generated for array-element
5, // implicit _5
{ // explicit _6
k4:7, // implicit _7
k5:8 // implicit _8
}, // </_6>
9 // implicit _9
], // </_4>
k6:10, // implicit _10
k7:11, // implicit _11
} // </_0>
AND a array of size 12(nodes count of the shape)
// _0 k0 k1 k2 _4 _5 _6 k4 k5 _9 k6 k7
["D", null,null,null, "A", null, "D", null,null,null,null,null]
in nvlang:
#0 will become a struct definition :
struct YourShapeName { //implicit _0
void* k0; //implicit _1
void* k1; //implicit _2
void* k2; //implicit _3
struct { //explicit _4
void* _5; //implicit _5
struct { //explicit _6
void* k4; //implicit _7
void* k5; //implicit _8
} //_6;
void* _9; //implicit _9
} // _4;
void* k6; //implicit _10
void* k7; //implicit _11
};
// void* can ALSO be uint64_t
AND a std::array<anything-length-is-8byte 16:48>
// _0 k0 k1 k2 _4 _5 _6 k4 k5 _9 k6 k7
["D", null,null,null, "A", null, "D", null,null,null,null,null]
// the highbit-16 save the type-meta-info
// the lowbit-48 save a ptr OR inplace-small-string(byte-length<=6) OR uint48_t
nvlang USE this-simple-data-structure to transfer stack-allocated-object
#1 your can also write AS {@@@[@{@@}@]@@} IF you dont care key-name
## in this secarino, it is same as nvzson
{ // explicit _0
_1:1, // explicit _1
_2:2, // explicit _2
_3:3, // explicit _3
_4:[ // explicit _4
5, // explicit _5
{ // explicit _6
_7:7, // explicit _7
_8:8 // explicit _8
}, // </_6>
9 // explicit _9
], // </_4>
_10:10, // explicit _10
_11:11, // explicit _11
} IF using array-only such as [@@@ [@ [@@] @] @@] , suggested for transfer
