need CASE or SWITCH loop in lua4

[cdebuhr]

hi,

for translation of english string values into german i need a case or switch loop like:

switch(weather)
{
case "rain": ....
case "sunny": ...
}

is something like this known or possible?

Chris,

Lua doesn't have a case switch but you can implement one - see the lua website.

But for what you want to do I thinka table will work ie.


EtoG = {
Rain = "xxxx",
Clear = "yyyy"
}

german = EtoG [weathertextvariable]

hi mike,

thx for your fast help.
but i tried to use your code here, and lua says "error: table index is nil".

EtoG = {
rain = "regen",
sunny = "sonnig",
clear = "klar"
}
german=EtoG[rain]
print (german)

what am i doing wrong?

when using a variable, do not use quotes.

if you are getting an error message, use a print to make sure the variable is not nil

Chris,

You are translating my script!
Do weather.com not have a german page? If you have a look at the xml feed, they may do... perhaps...


http://de.weather.com/

If you have a scout around on this site, and can find a german source of xml data on it. It maybe possible to change the weather script.

[cdebuhr]

CDBWetter = {
MostlyCloudy = "Meist bewölkt",
AMShowers = "Frühe Schauer",
Showers = "Schauer",
LightRain = "Leichter Regen",
PartlyCloudy = "Teils bewölkt",
ShowersLate = "Späte Schauer",
}

That MostlyCloudy should Mostly Cloudy, but that gives an error.

how can i use multiple-word-expressions?

[danward79]

You would have to either remove the space or add a character.

using GSUB or Format


x = "Mostly Cloudy"
x = gsub(x, " ", "")
print (x)

You may find this useful

hi dan, you are everywhere. ;-)

hmm. you shocked me with that german site! all my work for nothing? but no... the german site does not seem to offer xml-export of their data.

thx
chris

CDBWetter = {
MostlyCloudy = "Meist bewölkt",
AMShowers = "Frühe Schauer",
Showers = "Schauer",
LightRain = "Leichter Regen",
PartlyCloudy = "Teils bewölkt",
ShowersLate = "Späte Schauer",
}

That MostlyCloudy should Mostly Cloudy, but that gives an error.

Then create the table like this....

["Mostly Cloudy"] = ...

[cdebuhr]

thx. works fine now.
