# Yoctui
A terminal workspace for Yocto developers: build images, inspect what goes into
them, edit sources, and debug bring-up without losing your build context.
A persistent daemon keeps builds and development terminals available when you
close the UI and reconnect later.

</p>
## Features
- **Build and diagnose:** dashboard and insights, live BitBake tasks, logs,
warnings, errors, and saved build history.
- **Develop:** browse layers and recipes, use devtool and devshell, edit text
with syntax highlighting, compare files in a built-in two-pane diff tool,
and open GitUI in persistent terminal sessions.
- **Inspect images:** artifacts, rootfs package composition with a pie chart
and list, navigable files with permissions and ownership, systemd services,
D-Bus, and udev rules.
- **Bring up hardware:** organize project documents and requirements, and
record progress through bootloader, kernel, device tree, drivers, and rootfs.
- **Debug:** kernel and U-Boot menuconfig, DTS/DTB tools, QEMU boot,
SSH access, and remote kernel debugging with GDB.
Available actions depend on your Yocto build, generated artifacts, and installed
tools. See the [screenshots and workflows](https://github.com/0xbadcaffe/yoctui/blob/master/docs/screenshots.md)
for a closer look.
## Install
Linux, an 80×24+ terminal, Python 3, a C compiler/linker, and
[stable Rust/Cargo](https://www.rust-lang.org/tools/install) are required.
Install the prerequisites on Ubuntu/Debian (use equivalent packages on other
Linux distributions):
```bash
sudo apt update
sudo apt install -y build-essential pkg-config curl ca-certificates python3 git
```
Install Rust and Cargo using [rustup](https://rust-lang.org/tools/install/),
then make Cargo available in the current shell:
```bash
rustc --version
cargo --version
```
Install the official Yoctui release:
```bash
cargo install yoctui --locked -j 2
yoctui --version
```
For source builds, follow [Build from source](https://github.com/0xbadcaffe/yoctui/blob/master/docs/development.md#build-from-source).
QEMU, GDB, GitUI, and document viewers are optional tools needed for their
respective workflows. Live builds also need your Yocto release's host dependencies;
see [workspace setup](https://github.com/0xbadcaffe/yoctui/blob/master/docs/user-guide.md#start-a-workspace-safely).
## Quickstart
From an existing Poky checkout, initialize a build directory (adjust the paths):
```bash
export POKY_DIR="$HOME/src/poky"
export BUILDDIR="$POKY_DIR/build-yoctui"
source "$POKY_DIR/oe-init-build-env" "$BUILDDIR"
yoctui daemon status
```
Check `conf/local.conf` for your desired `MACHINE`, such as `qemux86-64`.
See [workspace setup](https://github.com/0xbadcaffe/yoctui/blob/master/docs/user-guide.md#start-a-workspace-safely)
for Yocto host dependencies and other source layouts.
If no daemon is running, or it already uses this build:
```bash
yoctui daemon start
yoctui --backend bridge --build-dir "$BUILDDIR"
```
To reconnect to an already-running daemon:
```bash
yoctui attach
```
To build a Poky image inside Yoctui:
1. Press `F8` to open **Images**, then `1` for the **Artifacts** tab.
2. Press `i` to choose an image, select `core-image-minimal`, and press `Enter`.
3. Press `b` to review the build. Check the target, then press `Enter` to confirm
and start building; `Esc` cancels the review.
4. Follow progress in **Tasks** (`F2`), build output in **Logs** (`F5`), and failures
in **Errors**.
Use `Tab` to focus the workspace if the Navigator has focus. These `i` and `b`
shortcuts belong to Images; editors and terminal sessions have their own keys.
`Alt+b` opens additional build options, `F1` opens Help, and `F12` opens the menu.
Opening Yoctui does not start a build; exiting leaves daemon-owned work running.
