# developer info

[![Build furnace](https://github.com/tildearrow/furnace/actions/workflows/build.yml/badge.svg)](https://github.com/tildearrow/furnace/actions/workflows/build.yml)

if you can't download these artifacts (because GitHub requires you to be logged in), [go here](https://nightly.link/tildearrow/furnace/workflows/build/master) instead.

**NOTE: do not download the project's source as a .zip or .tar.gz as these do not include the project's submodules which are necessary to proceed with building. please instead use Git as shown below.**

## dependencies

- CMake
- JACK (optional, macOS/Linux only)

if building under Windows or macOS, no additional dependencies are required.
otherwise, you may also need the following:

- libpulse
- libx11
- libasound
- libGL

some Linux distributions (e.g. Ubuntu or openSUSE) will require you to install the `-dev` versions of these.

## getting the source

type the following on a terminal/console: (make sure Git is installed)

```
git clone --recursive https://github.com/tildearrow/furnace.git
cd furnace
```

(the `--recursive` parameter ensures submodules are fetched as well)

## compilation

your typical CMake project.

### Windows using MSVC

as of now tildearrow uses MinGW for Windows builds, but thanks to OPNA2608 this works again!

from the developer tools command prompt:

```
mkdir build
cd build
cmake ..
msbuild ALL_BUILD.vcxproj
```

### macOS and Linux

```
mkdir build
cd build
cmake ..
make
```
Alternatively, build scripts are provided in the `scripts/` folder in the root of the repository.

### CMake options

To add an option from the command-line: `-D<NAME>=<VALUE>`  
Example: `cmake -DBUILD_GUI=OFF -DWARNINGS_ARE_ERRORS=ON ..`

Available options:

| Name | Default | Description |
| :--: | :-----: | ----------- |
| `BUILD_GUI` | `ON` | Build the tracker (disable to build only a headless player) |
| `USE_RTMIDI` | `ON` | Build with MIDI support using RtMidi |
| `USE_SDL2` | `ON` | Build with SDL2 (required to build with GUI) |
| `USE_SNDFILE` | `ON` | Build with libsndfile (required in order to work with audio files) |
| `USE_BACKWARD` | `ON` | Use backward-cpp to print a backtrace on crash/abort |
| `WITH_JACK` | `ON` if system-installed JACK detected, otherwise `OFF` | Whether to build with JACK support. Auto-detects if JACK is available |
| `SYSTEM_FFTW` | `OFF` | Use a system-installed version of FFTW instead of the vendored one |
| `SYSTEM_FMT` | `OFF` | Use a system-installed version of fmt instead of the vendored one |
| `SYSTEM_LIBSNDFILE` | `OFF` | Use a system-installed version of libsndfile instead of the vendored one |
| `SYSTEM_RTMIDI` | `OFF` | Use a system-installed version of RtMidi instead of the vendored one |
| `SYSTEM_ZLIB` | `OFF` | Use a system-installed version of zlib instead of the vendored one |
| `SYSTEM_SDL2` | `OFF` | Use a system-installed version of SDL2 instead of the vendored one |
| `WARNINGS_ARE_ERRORS` | `OFF` (but consider enabling this & reporting any errors that arise from it!) | Whether warnings in furnace's C++ code should be treated as errors |
| `WITH_DEMOS` | `ON` | Install demo songs on `make install` |
| `WITH_INSTRUMENTS` | `ON` | Install demo instruments on `make install` |

## console usage

```
./furnace
```

this opens the program.

```
./furnace -console <file>
```

this will play a compatible file.

```
./furnace -console -view commands <file>
```

this will play a compatible file and enable the commands view.

**note that these commands only actually work in Linux environments. on other command lines, such as Windows' Command Prompt, or MacOS Terminal, it may not work correctly.**

# frequently asked questions

> woah! 50 sound chips?! I can't believe it!

yup, it's real.

> where's the manual?

see [papers/](papers/doc/README.md). it's kind of incomplete, but at least the systems (sound chips) section is there.

> it doesn't open under macOS!

this is due to Apple's application signing policy. a workaround is to right click on the Furnace app icon and select Open.

> how do I use C64 absolute filter/duty?

on Instrument Editor in the C64 tab there are two options to toggle these.
also provided are two effects:

- `3xxx`: set fine duty.
- `4xxx`: set fine cutoff. `xxx` range is 000-7ff.
additionally, you can change the cutoff and/or duty as a macro inside an instrument by clicking the `absolute cutoff macro` and/or `absolute duty macro` checkbox at the bottom of the instrument. (for the filter, you also need to click the checkbox that says `volume macro is cutoff macro`.)

> how do I use PCM on a PCM-capable system?

two possibilities:
- the recommended way is by creating the "Sample" type instrument and assigning a sample to it.
- otherwise you may employ the DefleMask-compatible method, using `17xx` effect.

> my .dmf song sounds very odd at a certain point

file a bug report. use the Issues page. it's probably another playback inaccuracy.

> my .dmf song sounds correct, but it doesn't in DefleMask

file a bug report **here**. it still is a playback inaccuracy.

> my song sounds terrible after saving as .dmf!

the DefleMask format has several limitations. save in Furnace song format instead (.fur).

> how do I solo channels?

right click on the channel name.
