# parsing mudlet replay
|
||
|
|
|
||
|
|
* uses big endian signed integers
|
||
|
|
* format is: delta, number of bytes, chunk of bytes
|
||
|
|
|
||
|
|
## delta
|
||
|
|
* may be int32_t or int64_t but probably int32
|
||
|
|
* max delta with int32_t is around 12 days
|
||
|
|
* try as int32_t first and if num_butes < 1 or delta < 0 or num_bytes > buffer_size where
|
||
|
|
buffer_size is around 100000L then give up and try with int64_t and run tests again but
|
||
|
|
also add test delta <= int32_max
|
||
|
|
* delta change to int64_t was probably in 4.11.0 https://github.com/Mudlet/Mudlet/pull/4400
|
||
|
|
* delta fix back to int32_t was probably in 4.15.0 https://github.com/Mudlet/Mudlet/pull/5776
|
||
|
|
|
||
|
|
## num_bytes
|
||
|
|
* num bytes is int32_t
|
||
|
|
|
||
|
|
## chunk of bytes
|
||
|
|
* chunk can be assumed utf8, anything mudlet takes will be compatible, but mud probably uses ascii
