Get profiling data — lua_profile • luajr

After running Lua code with the profiler active (using lua_mode()), use this function to get the profiling data that has been collected.

Usage

lua_profile(flush = TRUE)

Arguments

flush: If TRUE, clears the internal profile data buffer (default); if FALSE, doesn't. (Set to FALSE if you want to 'peek' at the profiling data collected so far, but you want to collect more data to add to this later.)

Value

A data.frame.

Details

This function is experimental. Its interface and behaviour may change in subsequent versions of luajr.

See also

lua_mode() for generating the profiling data.

Examples

if (FALSE) { # \dontrun{
lua_mode(profile = TRUE)
pointless_computation = lua_func(
"function()
    local s = startval
    for i = 1,10^8 do
        s = math.sin(s)
        s = math.exp(s^2)
        s = s + 1
    end
    return s
end")
lua("startval = 100")
pointless_computation()
lua_mode(profile = FALSE)

prof = lua_profile()
} # }
