SHProto variable types

SHProto variable types

• optional parameters are marked with []
• if no parameters are passed then parentheses could be missed

Type	Description
u64/u32/u16/u8	textual unsigned 64/32/16/8 bit (handles symbols '0'-'9')
h64/h32/h16/h8	textual hex unsigned 64/32/16/8 bit (handles symbols 'A'-'F','0'-'9')
i64/i32/i16/i8	textual signed 64/32/16/8 bit (handles symbols '-','+','0'-'9')
b64/b32/b16/b8	binary variable 64/32/16/8 bit (handles all symbols)
string(maxlen[,len])	char string handles chars with code >= 0x20 and 0x09, not more than maxlen will be saved in C sting variable, if optional parameter len is passed the variable will not match more than len chars
substring(maxlen,\" \t\")	char string handles chars with code >= 0x20 and 0x09 until one of delimiter chars (listed in second parameter) will be matched (see format for []-token)
array(len)	binary array of length len
data([len])	continuous data of length len will be produced (extracted) from parser; if len is not passed data handles all chars till end of input stream or till put_\<var>_data will return false; if len is 0 the callback_func\:data(0) could be used as situation handler callback
( SHProto Pattern )	continuous data which is matched pattern will be produced (extracted) from parser; the pattern could be multi-line and contain branches or it could be the part of whole hierarchy tree (can contain any other SHProto variables)

More variable types will be added to support

• binary data types,
• data encodings.

User can add own data types.
