# cachyos-new-installer
CLI net-installer for CachyOS, inspired by manjaro-architect

This installer provides online installation for CachyOS.

Requirements
------------
* C++20 feature required (tested with GCC 11.1.0 and Clang 13(clang will not compile it with libstdc++ 11.1.0 because of c++20 standard ranges library)
Any compiler which support C++20 standard should work.

######
## Installing from source

This is tested on Arch Linux, but *any* recent Linux with latest C++20 compiler should do:

```sh
sudo pacman -Sy \
    base-devel cmake pkg-config make glibmm libnm
```

### Cloning the source code
```sh
git clone https://github.com/cachyos/new-cli-installer.git
cd new-cli-installer
```

### Building and Configuring
#### cmake(recommended):
To build, first, configure it(if you intend to install it globally, you
might also want `-DCMAKE_INSTALL_PREFIX=/usr`):
```sh
cmake -S . -B build
```
Second, build it:
```sh
cmake --build build
```

#### meson:
To build, first, configure it (if you intend to install it globally, you
might also want `--prefix=/usr`):
```sh
meson build
```
Second, compile it:
```sh
meson compile -C build
```

Optionally, to disable developer environment:
pass `-DENABLE_DEVENV=OFF` to cmake or `-Ddevenv=false` to meson when configuring the project.


### Libraries used in this project

* [Functional Terminal (X) User interface](https://github.com/ArthurSonzogni/FTXUI) used for TUI.
* [A modern formatting library](https://github.com/fmtlib/fmt) used for formatting strings, output and logging.
* [Fast C++ logging library](https://github.com/gabime/spdlog) used for logging process of the installer.
* [Parsing gigabytes of JSON per second](https://github.com/simdjson/simdjson) used for config deserialization.
* [Curl for People](https://github.com/libcpr/cpr) used for connection check and maybe in future fetching netinstall config from github.
* [Ranges](https://github.com/ericniebler/range-v3) used for ranges support with clang.
