Function Documentation

assert ( len  = =read_bytes)
bool encode_check_json_key ( const typval_T *const  tv)

Check whether given key can be used in json_encode()

Parameters
[in]tvKey to check.
int encode_list_write ( void *const  data,
const char *const  buf,
const size_t  len 
)

Msgpack callback for writing to readfile()-style list.

int encode_read_from_list ( ListReaderState *const  state,
char *const  buf,
const size_t  nbuf,
size_t *const  read_bytes 
)

Read bytes from list

Parameters
[in,out]stateStructure describing position in list from which reading should start. Is updated to reflect position at which reading ended.
[out]bufBuffer to write to.
[in]nbufBuffer length.
[out]read_bytesIs set to amount of bytes read.
Returns
OK when reading was finished, FAIL in case of error (i.e. list item was not a string), NOTDONE if reading was successful, but there are more bytes to read.
char* encode_tv2echo ( typval_T *  tv,
size_t *  len 
)

Return a string with the string representation of a variable. Does not put quotes around strings, as ":echo" displays values.

Parameters
[in]tvtypval_T to convert.
[out]lenLocation where length of the result will be saved.
Returns
String representation of the variable or NULL.
char* encode_tv2json ( typval_T *  tv,
size_t *  len 
)

Return a string with the string representation of a variable. Puts quotes around strings, so that they can be parsed back by eval().

Parameters
[in]tvtypval_T to convert.
[out]lenLocation where length of the result will be saved.
Returns
String representation of the variable or NULL.
char* encode_tv2string ( typval_T *  tv,
size_t *  len 
)

Return a string with the string representation of a variable. Puts quotes around strings, so that they can be parsed back by eval().

Parameters
[in]tvtypval_T to convert.
[out]lenLocation where length of the result will be saved.
Returns
String representation of the variable or NULL.
bool encode_vim_list_to_buf ( const list_T *const  list,
size_t *const  ret_len,
char **const  ret_buf 
)

Convert readfile()-style list to a char * buffer with length

Parameters
[in]listConverted list.
[out]ret_lenResulting buffer length.
[out]ret_bufAllocated buffer with the result or NULL if ret_len is zero.
Returns
true in case of success, false in case of failure.
