Rewrite the Installer app on the Montauk Toolkit (Canvas + gui/mtk widgets, theme, hover states, scrollbar) replacing the hand-rolled px_* renderer and bespoke TrueType usage. Add a new "Software" step: an expandable checkbox tree for optional components (Montauk SDK with gcc/g++, binutils, tcc, lua sub-items; Games; Office; Internet apps; Printing; experimental httpd and SDR). Unchecked components' paths are excluded from the install copy, with a longest-path ownership rule so e.g. sdk/tcc installs even when the rest of the SDK is deselected. The update flow refreshes only the components the target already has. Add tri-state checkbox and disclosure-arrow widgets to the MTK toolkit (anti-aliased, supersampled). Merge tcc and lua into 0:/sdk (0:/sdk/tcc, 0:/sdk/lua) and drop 0:/lib: update tcc config.h, lua luaconf.h, both Makefiles, the devkit clean scope, man pages and montaukos.org notices. Make printing optional: init skips printd when 0:/os/printd.elf is absent. Co-Authored-By: Claude Opus 4.8 <[email protected]>

.SH NAME
|
|
intro - introduction to MontaukOS userspace
|
|
|
|
.SH DESCRIPTION
|
|
MontaukOS is a hobbyist 64-bit operating system written in C++20,
|
|
currently at version 0.1.7 (API version 8). Userspace programs
|
|
run in Ring 3, are loaded as static ELF64 binaries, and
|
|
communicate with the kernel through the x86-64 SYSCALL/SYSRET
|
|
mechanism (150 syscalls -- see syscalls(2)).
|
|
|
|
Programs are compiled with a freestanding cross-compiler and
|
|
linked at virtual address 0x400000. There is no standard C
|
|
library for C++ programs -- all system interaction goes through
|
|
the montauk:: syscall wrappers. A desktop environment with a
|
|
window server, GUI apps, and Bluetooth/audio/networking stacks
|
|
runs on top of the same syscall API.
|
|
|
|
.SH GETTING STARTED
|
|
To write a new system/CLI program, create a directory under
|
|
programs/src/ with a main.cpp file. The entry point is:
|
|
|
|
extern "C" void _start() { ... }
|
|
|
|
There is no argc/argv. Use montauk::getargs() to retrieve any
|
|
arguments passed by the parent process. Include <montauk/syscall.h>
|
|
for the full typed syscall API. GUI apps additionally use
|
|
win_create()/win_poll()/win_present() from montauk/Window.hpp
|
|
(see framebuffer(2)).
|
|
|
|
Build with:
|
|
|
|
cd programs && make
|
|
|
|
System/CLI binaries appear in programs/bin/os/; GUI app bundles
|
|
(ELF + manifest.toml + icon) appear under programs/bin/apps/<name>/.
|
|
|
|
.SH RAMDISK LAYOUT
|
|
The boot ramdisk is mounted as drive 0 with the following
|
|
directory structure:
|
|
|
|
0:/os/ System/CLI binaries (shell, init, man, etc.),
|
|
plus os-owned data: certs/, firmware/,
|
|
licenses/, wallpapers/
|
|
0:/apps/ GUI app bundles, one directory per app
|
|
(<app>.elf + manifest.toml + icon)
|
|
0:/config/ System-wide config TOMLs
|
|
0:/users/<name>/ Per-user home directories (created at
|
|
login), with Music/, Videos/, Pictures/,
|
|
config/ subdirectories
|
|
0:/fonts/ Shared fonts
|
|
0:/icons/ Shared icons
|
|
0:/man/ Manual pages
|
|
0:/www/ Web server content
|
|
0:/sdk/ Montauk SDK (native gcc/binutils, TinyCC,
|
|
Lua, headers and libraries), when installed
|
|
0:/boot/ Kernel, bootloader, ramdisk image
|
|
|
|
There is no 0:/games/, 0:/common/, 0:/home/, or 0:/etc/ --
|
|
these were used by earlier single-user releases and no longer
|
|
exist. 0:/lib/ was merged into 0:/sdk/. Games and other GUI
|
|
programs (including doom) ship as bundles under 0:/apps/.
|
|
|
|
.SH SHELL
|
|
The interactive shell is the primary way to interact with
|
|
MontaukOS. Commands are resolved against the current directory
|
|
first, then 0:/os/. Type 'help' at the shell prompt for a list
|
|
of commands. Use 'man shell' for detailed shell documentation.
