From 0d73f6d8ae32f1cd48ce9f089b902eb0877605e1 Mon Sep 17 00:00:00 2001 From: "Adrian C. (anrxc)" Date: Mon, 26 Oct 2009 20:32:48 +0100 Subject: Ensure returned numbers are of type number Thanks to Felix for bringing this to my attention.

We have widgets of type textbox for one, and a lot of string concatenation happens. Strings are formatted, markup is applied... --- thermal.lua | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'thermal.lua') diff --git a/thermal.lua b/thermal.lua index 1697eb0..f83be13 100644 --- a/thermal.lua +++ b/thermal.lua @@ -4,6 +4,7 @@ --------------------------------------------------- -- {{{ Grab environment +local tonumber = tonumber local io = { open = io.open } local setmetatable = setmetatable local string = { match = string.match } @@ -19,11 +20,11 @@ local function worker(format, thermal_zone) -- Get an ACPI thermal zone local f = io.open("/proc/acpi/thermal_zone/"..thermal_zone.."/temperature") -- Handler for incompetent users - if not f then return {"N/A"} end + if not f then return {0} end local line = f:read("*line") f:close() - local temperature = string.match(line, "[%d]?[%d]?[%d]") + local temperature = tonumber(string.match(line, "[%d]?[%d]?[%d]")) return {temperature} end -- cgit v1.2.3
