Last updated March 2020
Name
msys.counter.read — Read the specified counter
Synopsis
msys.counter.read(object_or_path);
Description
Returns the current integer value of the given counter object or path. For example, msys.counter.read("/sites/example/errors") and msys.counter.read(c) are valid (where c was a successful return value of msys.counter.open).
require("msys.core"); require("msys.counter"); local mod = {}; local ct = msys.counter.open("/lua/test"); function mod:validate_mailfrom(str, accept, vctx) str = tostring(str); if (string.find(str, "count@test.example.com") != nil) then msys.counter.inc(ct); elseif (string.find(str, "blargh@test.example.com") != nil) then c = msys.counter.open("/lua/blargh", msys.counter.RELAXED); msys.counter.add(c, 1024); elseif (string.find(str, "blarghstring@test.example.com") != nil) then msys.counter.add("/lua/blargh", 3); elseif (string.find(str, "blarghinc@test.example.com") != nil) then msys.counter.inc("/lua/blargh"); elseif (string.find(str, "unlink@test.example.com") != nil) then msys.counter.unlink("/lua/blargh"); elseif (string.find(str, "readname@test.example.com") != nil) then c = msys.counter.open("/readname"); msys.counter.add(c, msys.counter.read("/lua/blargh")); elseif (string.find(str, "readcounter@test.example.com") != nil) then c = msys.counter.open("/readcounter"); msys.counter.add(c, msys.counter.read(msys.counter.open("/lua/blargh"))); elseif (string.find(str, "resetname@test.example.com") != nil) then msys.counter.reset("/lua/blargh"); elseif (string.find(str, "resetcounter@test.example.com") != nil) then c = msys.counter.open("/lua/test"); msys.counter.reset(c); end return msys.core.VALIDATE_CONT; end msys.registerModule("counter", mod);
Enable this function with the statement require('msys.counter');.
