Nice work, although I had some trouble reading the docs ;-)
Anyway, here is a little demo for the FAM module. Mostly I
wrote this just to check things out but maybe someone else
might find it useful...
-------------------------------
#!/usr/bin/env lua
require "fam"
if arg[1]=="-h" or arg[1]=="--help"
then
print("\nWatches a directory for changes.\n\nUsage:")
print(arg[0].." [directory] [interval]\n")
os.exit(0)
end
function fail(msg) print("Fatal: "..msg); os.exit(1) end
local dir = arg[1] or os.getenv("HOME") -- What to watch
dir = dir:match("^/.*") or fail("Path must be absolute.")
local wait = arg[2] or 5 -- Seconds between updates
wait = tonumber(wait) or fail("Interval must be a number.")
local fc = fam.open() or fail("FAM library init failed.")
local fr = fam.monitorDirectory(fc, dir)
or fail("Failed to monitor `"..dir.."'\nDoes it exist?")
print(fam._VERSION)
print("Monitoring "..dir)
print("At "..wait.." second intervals...")
repeat
while fam.waitEvent(fc,wait) do
while fam.pendingEvent(fc) > 0 do
local fe = fam.nextEvent(fc)
if fe then
if fe.code~="Exists" and fe.code~="EndExist" then
print(fe.code .." "..fe.filename.." in "..fe.path)
end
end
end
end
until false
-- Actually, we never get here, but if we did...
fam.monitorCancel(fc,fr)
fam.close(fc)
-------------------------------
Did I get it right?
