Solidity sourceMap

Definition

AST sourceMap

s:l:f

(e.g. 1:2:1;1:9:1;2:1:2;2:1:2;2:1:2)

s: byte-offset to the start of the range in the source file

l: length of the source range in bytes

f: source index (in sourceList, which is part of the combined-json)

bytecode sourceMap

list of s:l:f:j separated by ;

(e.g. 10630:2840:0:-;;;10803:1458;;;;;;;;;)

Each of these elements corresponds to an instruction

s, l, f are the same of AST sourceMap's

j can be either i, o or -

i: jump instruction goes into a function (jump in?)

o:returns from a function (jump out?)

-: regular jump as part of e.g. a loop

If a field is empty, the value of the preceding element is used.

e.g. 1:2:1;1:9:1;2:1:2;2:1:2;2:1:2 and 1:2:1;:9;2:1:2;; represent the same information

If a : is missing, all following fields are considered empty.
