The sys module provides access to system-specific parameters and functions.

Attributes

sys.bits

sys.bits

The number of bits in a Teascript integer, either 32 or 64 depending on the architecture.

Example

import sys

// Check architecture word size
print("Word size: " + sys.bits + " bits")

// Use for bitwise operations
if sys.bits == 64
{
    print("Running on 64-bit architecture")
    var large_number = 1 << 40
    print("Large number:", large_number)
}
else
{
    print("Running on 32-bit architecture")
}

sys.byteorder

sys.byteorder

A string representing the byte order of the system, either “little” or “big”.

Example

import sys

// Check system byte order
print("Byte order: " + sys.byteorder)

// Handle binary data appropriately
if sys.byteorder == "little"
{
    print("Little-endian system")
}
else
{
    print("Big-endian system")
}

// Practical example: network byte order conversion
var is_little_endian = sys.byteorder == "little"
print("Needs byte swapping for network: " + is_little_endian)

sys.argv

sys.argv

A list of command-line arguments passed to the Teascript program.

Example

import sys

// Print all arguments
print("Arguments:")
for const arg in sys.argv
{
    print("  " + arg)
}

// Check for specific flags
var verbose = false
for const arg in sys.argv
{
    if arg == "--verbose" or arg == "-v"
    {
        verbose = true
    }
}

if verbose
{
    print("Verbose mode enabled")
}

// Access specific arguments
if sys.argv.length > 0
{
    print("First argument: " + sys.argv[0])
}

sys.version

sys.version

A map containing the version information of the Teascript interpreter.

Attributes

  • major: The major version number
  • minor: The minor version number
  • patch: The patch version number

Example

import sys

// Display version information
print("Teascript version: " + sys.version.major + "." + sys.version.minor + "." + sys.version.patch)

// Check for minimum version
var required_major = 1
var required_minor = 0

if sys.version.major > required_major or (sys.version.major == required_major and sys.version.minor >= required_minor)
{
    print("Version requirement satisfied")
}
else
{
    print("Please upgrade Teascript")
}

// Feature detection based on version
if sys.version.major >= 2
{
    print("Using modern features")
}

sys.loaders

sys.loaders

A list of module loaders available to the Teascript runtime.

Example

import sys

// Display available loaders
print("Available loaders:")
for const loader in sys.loaders
{
    print("  " + loader)
}

// Check loader availability
var has_custom_loader = false
for const loader in sys.loaders
{
    if loader == "custom"
    {
        has_custom_loader = true
    }
}

if has_custom_loader
{
    print("Custom loader is available")
}

Functions

sys.exit()

function sys.exit(status)

The function exit terminates the program with the given status.

Arguments

  • status: An optional boolean or integer exit status. If true or omitted, exits with success (0). If false, exits with failure (1). If an integer, uses that as the exit code.

Example

import sys

// Exit with success
if condition_met
{
    sys.exit(true)
}

// Exit with failure
if error_occurred
{
    sys.exit(false)
}

// Exit with specific code
if critical_error
{
    sys.exit(42)
}

// Default success exit
sys.exit()
