Detect battery percentage with applescript - applescript

Question

How would I detect what my computer's battery percentage is at and set it to a variable using applescript? All answers to similar questions say to install additional software, but I would like to do this with purely applescript. Is this possible? I've also tried searching through the applescript library with no success.

Answer 1

on run
set theBattString to (do shell script "pmset -g batt")
-- the above will return something like...
-- Now drawing from 'Battery Power' -InternalBattery-0 82%; discharging; 4:06 remaining
end run
Now you can parse theBattString to get the information you'd like from it.
Another option...
on run
do shell script "ioreg -l | grep -i capacity | tr '\\n' ' | ' | awk '{printf(\"%.2f%%\\n\", $10/$5 * 100)}'"
-- will output...
-- 79.63%
end run

Answer 2

The applescript unsigned variable can be used like a signed FileMaker variable... the ** can be removed I tried it Bold it
set batteryPercent to do shell script "pmset -g batt "
tell application "FileMaker Pro.app"
tell table "Power Test Results"
tell record 1
set cell "Test percentage via AppleScript Global" to batteryPercent
end tell
end tell
end tell

Answer 3

Thank ThrowBackDewd for his answer.
I made something a bit strange but it works for me.
Here is the AppleScript
[EDIT]
Here a more efficient code thanks to user #user3439894.
set batteryPercent to word 6 of paragraph 2 of (do shell script "pmset -g batt")
if batteryPercent < 40 then
beep
repeat 3 times
say "Attention " & batteryPercent & "%" & " before shut down."
display notification "Attention " & batteryPercent & "%" & " of charge before shut down." sound name "Glass"
end repeat
end if
idle application
on idle
set batteryPercent to word 6 of paragraph 2 of (do shell script "pmset -g batt")
if batteryPercent < 40 then
repeat 3 times
beep
say "Attention " & batteryPercent & "%" & " of charge before shut down."
display notification "Attention " & batteryPercent & "%" & " of charge before shut down." sound name "Glass"
end repeat
end if
return 60
end idle
[First post]
set theBattString to (do shell script "pmset -g batt")
-- the above will return something like...
-- Now drawing from 'Battery Power' -InternalBattery-0 82%; discharging; 4:06 remaining
set batteryLevel to splitText(theBattString, space)
--set totalItembatLvl to length of batteryLevel
set remainingTime to item 9 of batteryLevel
if remainingTime < "2:40" then
display alert "low battery " & remainingTime & " before shut down."
--batteryLevel & " " & remainingTime
end if
on splitText(theText, theDelimiter)
set AppleScript's text item delimiters to theDelimiter
set theTextItems to every text item of theText
set AppleScript's text item delimiters to ""
return theTextItems
end splitText
on getPositionOfItemInList(theItem, theList)
repeat with a from 1 to count of theList
if item a of theList is theItem then return a
end repeat
return 0
end getPositionOfItemInList
You can add it in an idle statement and check every minute for your battery level.
Any suggestions or corrections will be appreciated.
Regards.
