OneTool

OneTool - a single static Linux binary that contains multiple built-in tools

The long-term idea is simple: one executable, one CLI entrypoint, many capabilities implemented from scratch inside the project.

Warning: Some parts of the code were written by AI because I don't really understand HTTP

status

implemented tools:

• lastmod - prints the last modification time of a file (lastmod = last modification)

• reboot - reboot the system

• shutdown - shut down the system

• exec - execute file (exec = execute)

• down - HTTP downloader (down = downloader)

• ping - ICMP ping with stats

• lmake - run bundled lmake build tool

• lpack - pack lua script into ELF runtime (lpack = lua packager)

• mlink - minimalistic ELF64 x86-64 linker (mlink = minimalistic linker)

• taskmng - TUI task manager with process control (taskmng = task manager)

• gapi_supported - check available graphics API (gapi_supported = graphics api supported)

• srapi_demo - render a test frame with SRAPI

• srvid2mp4 - convert .srvid screen recordings to mp4/webm via ffmpeg

• fsinfo - filesystem info (fsinfo = filesystem info)

• fsize - print file size (fsize = file size)

• ls - list files (ls = list)

• cat - print files content

• free - show memory usage

• yap - YAP language interpreter

• userc - interactive user control (add/del/edit users) (userc = user control)

• nsetup - simple network setup via DHCP (nsetup = network setup)

• size - prints elf sections size

• nm - prints elf symbols

• click - SRAPI click-the-cube minigame (15s round)

• ranal_demo - demo of the ranal GUI library

• about - KDE-like system information viewer

• swm - simple window manager / compositor (sprot v0.1) (swm = simple window manager)

• sprot_hello - minimal sprot client (draws a colored rectangle)

• term - GUI terminal built on ranal (standalone or as a swm client via --swm)

• wayland_bridge - Wayland client compatibility bridge for swm (wlbridge) framework parts:

• libs/net - network library for URL parsing, HTTP and transport

• libs/TUI - TUI library

• libs/elf - ELF parser lib

• libs/memory - checked allocation helpers

• libs/srapi - simple rendering API (srapi = simple rendering api)

• libs/gui/ranal - retained-mode GUI library on top of srapi (ranal = raylib analog (name deprecated))

• libs/gui/sprot - simple wire protocol for compositor/client comms (unix socket + memfd buffers) (sprot = simple protocol)

• libs/gui/swm - simple window manager / compositor (sprot v0.1) (swm = simple window manager)

build

requirement:

• clang
• make

build:

make

delete binaries:

make clean

add custom tools

You can bundle extra C tools into onetool at build time without editing main.c.

Add a line to config/extra_tools.manifest Run make

Manifest format:

name|source|description|argv0_mode|extra_cflags

Example:

yap|mofl/languages/yap/yap.c|YAP language interpreter|tool|

Notes:

• the source file must expose a normal main(int argc, char **argv)
• the build renames that main automatically during compilation
• argv0_mode can be tool or onetool

tui

You can launch TUI by:

./onetool tui

Themes and built-in tool forms are embedded directly into the binary by tui.c.

Inside TUI:

• Enter opens the selected tool form
• N opens global settings
• T quickly cycles themes
• inside a tool form, Enter runs the tool
• settings let you change the launch path for tools and edit theme colors live

If a tool does not have a built-in TUI form, OneTool falls back to a generic screen with Extra args, so all tools can still be launched.

How version counting works

x.r.f x = when r > 9 r = global update or new tool f = small update or bug fix
