Hi,
from the user input I get the wanted baudrate as an raw value
- say
115200.
I have to map this to a constant (in case of luars) which is
"rs232.RS232_BAUD_115200"
which is a string despite the "." in the middle...
To prevent looping over all constants and forests of if-then-else
stuff (there are more constants to map) I thought, that a table
could do that...
But
baudrate = { "115200", "rs232.RS232_BAUD_115200" }
and
ui=115200
gives me another problem:
baudrate.[ui]
baudrate.[tostring(ui)]
baudrate.ui
produces all 'nil' wiith lua -i
How can I map teh user input directly to the constant without
iterating and/or 'if-ing' over dozens of possibilities?
Thank you very much in advance for your help and patience with
a lua newbie... ! :)
Best regards,
mcc
