My first CHDK script... does it look good?

I just wanted to run some tests with my camera's battery in relation to temperature, so I made this little Lua script. This is my first script that I have made for CHDK, so hopefully it works! I will be testing it soon, but if anyone can see an error could they please let me know?

--Test 1
--[[
rem Test1 by mrShrimp
@title batterytest1
@param m free memory percentage
@default m 1
@param i shoot interval
@default i 3000
@param b battery dead
@default b false
@param n shot number
@default n 0
]]

freemem, interval, deadbatt, shotnumber = m, i, b, n
--Jump right into it!

x = get_meminfo()
original = x[11]
print("we got this far")
while deadbatt == false do
   table1 = get_meminfo()
   if table1 ~= nil then
      freemem = (table1[11]/original) --NewMem/StartingMem, default of 1
      print(freemem)
   else
      print("err1:notable")
   end
   sleep(3000)
   --Take the shot
   press("shoot_half")
   repeat
      sleep(50)
until get_shooting() == true
   click("shoot_full")
   release("shoot_half")
   shotnumber = shotnumber+1
   print("Shots taken: " .. shotnumber)
   --For initial testing purposes
   if shotnumber == 20 then
      deadbatt = true
      print("Script End")
   end
end

Also, this is my first time on the forums so I just realized that there might be rules about no script posting. Sorry if that's the case 0_0

Edit: I have found a lot of errors in the past 10 minutes, and I realize I probably should have waited a bit to ask for help. Anyways, the above post is the revised script as of now.

Script posting is encouraged but its nicer if you post using the formatting provide by the "#" button on the edit tool bar so that your script is inserted something like this :

Code: [Select]

--Test 1
--[[
rem 20080815 test script by xxx
@title batterytest1
@param m free memory percentage
@default a 1
@param i shoot interval
@default b 3000
@param b battery dead
@default h false
@param n shot number
@default n 0
]]

freemem, interval, deadbatt shotnumber = m, i, b, n
--Jump right into it!

while deadbatt == false do
   table1 = get_meminfo()
   if table1 ~= nil then
      freemem = (table1[11]/table1[11]) --NewMem/StartingMem, default of 1
      print(freemem)
   else
      print("err1:notable")
   end
   sleep(3000)
   --Take the shot
   press("shoot_half")
   repeat
      sleep(50)
    until get_shooting() == true
   click("shoot_full")
   release("shoot_half")
   shotnumber = shotnumber+1
   print("Shots taken: " .. shotnumber)
   --For initial testing purposes
   if shotnumber == 20 then
      deadbatt = true
      print("Script End")
   end
end

Ok, thanks! I'm just getting the hang of this, and I was wondering how I specify the heapname for function get_meminfo, and is the free_size value a numeric value?

Latest Code:

Code: [Select]

--Test 1
--[[
rem Test1 by mrShrimp
@title batterytest1
@param m free memory percentage
@default m 1
@param i shoot interval
@default i 3000
@param b battery dead
@default b 0
@param n shot number
@default n 0
]]

freemem, interval, deadbatt, shotnumber = m, i, b, n
--Jump right into it!

x = get_meminfo()
original = x[11]
print("we got this far")
while deadbatt == 0 do
	table1 = get_meminfo()
	if table1 ~= nil then
		freemem = (table1[11]/original) --NewMem/StartingMem, default of 1
		print(freemem)
	else
		print("err1:notable")
	end
	sleep(3000)
	--Take the shot
	press("shoot_half")
	repeat
		sleep(50)
    until get_shooting() == true
	click("shoot_full")
	release("shoot_half")
	shotnumber = shotnumber+1
	print("Shots taken: " .. shotnumber)
	--For initial testing purposes
	if shotnumber == 20 then
		deadbatt = 1
		print("Script End")
	end
end

Eh, sorry for bothering you all. After a bit of research, I found an alternative way to accomplish what I wanted to do. Thanks waterwingz for your help!

You can not use 'false' in params - there are only integer values possible. ~~Nevertheless in the so-called unstable trunk you can have more possibilities:~~ Nevertheless, you can use special keywords to have more possibilities:

you can use @range keyword to set the allowed range for parameter. Example:

Code: [Select]

@param x
@default x 4
@range x 1 10

above code allows user to set the number from 1 to 10.

If range is set to 0-1 then in menu a boolean-like value is showed:

Code: [Select]

@param c foobar
@default c 0
@range c 0 1

What user will see in menu:

Code: [Select]

foobar       [false]

You can also use the @values keyword for setting the list of settings. Example:

Code: [Select]

@param f author
@default f 2
@range f alva bethe gamov

user will see:

Code: [Select]

author     [  bethe ]

The (integer) value of the f param depends on the user select. f=1 if alva is selected, 2 if bethe and so on.

You can also use the @values keyword for setting the list of settings. Example:...

@range and @values are also available in the release-1.0 'stable' branch so that scripts remain compatible between versions.
