Picotron API > Functions > Kernel Functions

Overview

Kernel functions are special functions allocated for boot.lua, the window manager and the process manager.

These are disabled for cartridges through the use of /system/lib/jettison.lua

This can be re-enabled through the use of the following snippet first thing in the program; this will temporarily disable jettison.lua to re-run itself, then enabling jettison.lua and exiting the program.

This snippet is sourced from @Soupster (found in the Picotron Discord server).

if not _warp_mouse then
    local jettison = fetch"/system/lib/jettison.lua" -- Store a copy of jettison.lua
    store("/system/lib/jettison.lua", "") -- Remove the file contents / disable jettison.lua

    -- Wait a safe amount of time for the changes to update
    for i = 1, 5 do flip() end

    create_process(pwd()) -- Create a copy of the program (pwd() returns the program's location)

    for i = 1, 5 do flip() end -- Ensure the process has been created with the non-existent jettison.

    store("/system/lib/jettison.lua", jettison) -- Fix jettison.lua
    exit() -- Close the program
end

It may be of use to note that zep writes "kernel" as "kernal", seen through comments and functions like _userland_to_kernal_path.
