Function Documentation

static YCPValue Eval ( const YCPValue &  v)
static

eval Evaluate a YCP value. See also the builtin ``, which is kind of the counterpart to eval.

eval (``(1+2)) -> 3

static YCPString Getenv ( const YCPString &  name)
static

getenv Change or add an environment variable The getenv(variable) function returns the value of variable from environment. If variable doesn't exist the value is NULL.

Parameters
stringname
Returns
string value getenv ("USER") -> "root" getenv ("LC_CTYPE") -> "en_US.UTF-8"

Referenced by YCPBuiltinMisc::YCPBuiltinMisc().

static YCPInteger Random ( const YCPInteger &  max)
static

random Random number generator. Returns a random integer in the interval [0,MAX). srandom must be activated to get really random numbers.

Parameters
integerMAX
Returns
integer Returns integer in the interval [0,MAX). random(100) -> 82 random(100) -> 36

static YCPString s_sformat ( const YCPValue &  format,
const YCPValue &  _argv 
)
static

sformat Format a String FORM is a string that may contains placeholders %1, %2, ... Each placeholder is substituted with the argument converted to string whose number is after the %. Only 1-9 are allowed by now. The percentage sign is donated with %%.

Parameters
stringFORM
anyPAR1
anyPAR2
