Hi Baptiste,
Lua converters functions are automatically generated from registered
haproxy converters, So converters can't have specific documentation.
The only one rules are:
- The first argument is the input data.
- Next arguments are the arguments described in classic HAProxy doc.
So, the following HAProxy configuration example:
str(test),conv(33)
I written like this in Lua:
txn.c:conv("test", 33)
If you have some useful example, do not hesitate to improve the
documentation.
BR,
Thierry
