LuaDBC is a parser for WoW's DB2 files implemented in Lua.

Installation

The dbc/ directory should go somewhere matched by Lua's package.path. This might be the current working directory, /usr/local/share/lua/5.1/, or a lua subdirectory in the directory containing your Lua executable.

API

dbc = require("dbc")
Loads the DBC/DB2-parsing module.
header = dbc.header("data")
Returns a table of properties derived from the DBC header of data.
iterator, data = dbc.rows("data", "rowSignature"[, loose])
Returns an iterator over the rows in data, returning the row index (or row ID if specified by the file), and the fields specified in rowSignature, where each character represents a field type:
.
Skip field, returning no value.
i
Signed integer, returns a number.
u
Unsigned integer, returns a number.
f
32-bit IEEE 754 float, returns a number.
s
Null-terminated string, returns a string (without the terminator).
L
64-bit unsigned integer, returns a table t = {lo, hi, m=2^32}, such that the integer's value is t[1] + t.m * t[2].
F
Foreign key associated with the record, returns a number. This field can be used at any position in a signature if the DBC file contains a foreign key mapping, and does not advance the current field pointer.
?
Automatically guess column type.
Each field type character may be preceded by an integer specifying the number of repetitions of that field type (thus u3fs and ufffs are equivalent), or * to repeat the field type until the end of row.
Curly brackets may be used to place parts of the signature inside a table: the iterator for u{3f}s returns the row index/ID, followed by a number, an array with three numbers, and a string.
If a DBC signature begins with a curly bracket, the resulting table is returned as the iterator's first return value. The row index/ID is assigned to the table's [0] key.
Unless loose is truthy, rowSignature must describe all the fields present in the file.
