character string

[Chris]

Hello,

I want to cut part of a value : 


-- value1 --> 11:36:23, Samedi

I want to recover the first part - hour without the day

-- 11:36:23

Thanks.

Hi,
this could work

local value1 = '11:36:23, Samedi'
local data = '%d%d:%d%d:%d%d'
local res = string.match(value1, data)
log(res)

Hello,

Thanks for your answer, but it doesn't work --> value: 0:00:00

value1 = grp.getvalue("32/1/20")
value2 = grp.getvalue("32/1/21")

local data = '%d%d:%d%d:%d%d'

local res = string.match(value2, data)

grp.write('32/1/30', res)

grp.write('32/1/28', value1)

log(res)

Hi Chris, waht kind of datatype is your "32/1/21" ?

and what result do you get if you do

Code:

value2 = grp.getvalue("32/1/21")
log(value2)

grp.write('32/1/30', res)

grp.write('32/1/28', value1)

log(res)

Script works if you pass a string, if you pass a table it can't work

Hi Dré,

DP : 10. 3 octets heure / jour


User script:6: bad argument #1 to 'match' (string expected, got table)
stack traceback:
[C]: in function 'match'
User script:6: in main chunk

stack traceback:

Try to change in this this way

local res = string.match(tostring(value2[1], data)
Best regards

[Dré]

try this

Code:

value1 = grp.getvalue('32/1/20')


-- time table
time = {
day = wday,
hour = value1.hour,
minute = value1.min,
second = value1.sec,
}

-- date table
date = {
day = value1.day,
month = value1.month,
year = value1.year,
}


value1 = string.format("%02d", value1.hour)  .. ":" .. string.format("%02d", value1.min)  .. ":" .. string.format("%02d", value1.sec)
log(value1)


grp.write('32/1/30', value1)
log(value1)

---

I also see there was use " insteed of '
value1 = grp.getvalue("32/1/20")

Dré your solution works, thank you!
CristianAgata, thank you, I'll try your method soon,
good evening !

Next firmware will have an option to hide day and/or seconds for data type 10 (3 byte time / day).

Dré's script is correct. string.format supports multiple arguments so the script can be shorter. There's no different in using single or double quotes in Lua.

Code:

value = event.getvalue()
time = string.format('%d:%02d:%02d', value.hour, value.min, value.sec)
log(time)
