runtime

The runtime module provides information about the current platform, architecture, and runtime environment.

Functions

Function	Returns	Description
runtime.platform()	string	Operating system name (e.g. "linux", "darwin", "windows")
runtime.arch()	string	CPU architecture (e.g. "amd64", "arm64")
runtime.cpu_count()	int	Number of logical CPUs
runtime.version()	string	Starkite version string
runtime.go_version()	string	Go runtime version
runtime.uname()	dict	System information dictionary with keys: system, node, release, version, machine (Unix only; returns an error on Windows)

Examples

Platform detection

if runtime.platform() == "linux":
    exec("apt-get update")
elif runtime.platform() == "darwin":
    exec("brew update")

Architecture-specific builds

os_name = runtime.platform()
arch = runtime.arch()
target = os_name + "/" + arch

print("Building for:", target)
exec("GOOS=%s GOARCH=%s go build -o app ./cmd" % (os_name, arch))

System information

info = runtime.uname()
print("System:", info["system"])
print("Host:", info["node"])
print("Kernel:", info["release"])
print("Arch:", info["machine"])

Version info

print("kite version:", runtime.version())
print("Go version:", runtime.go_version())
print("CPUs:", runtime.cpu_count())

Cross-platform script

bin_name = "myapp"
if runtime.platform() == "windows":
    bin_name += ".exe"

exec("go build -o " + bin_name)
