## Summary

Filare (the new name for WireViz) is a tool for documenting cables, wiring harnesses and connector pinouts. It takes plain text, YAML-formatted files as input and produces graphical output (SVG, PNG, ...) via [GraphViz](https://www.graphviz.org/). It handles automatic BOM (Bill of Materials) creation and a number of extras.

## Features

- Filare input files are fully text based
  - No special editor required
  - Human readable
  - Easy version control
  - YAML syntax
  - UTF-8 input and output files for special character support
- Understands and uses color abbreviations as per [IEC 60757](https://en.wikipedia.org/wiki/Electronic_color_code#Color_band_system) (black=BK, red=RD, ...)
  <!-- * Optionally outputs colors as abbreviation (e.g. 'YE'), full name (e.g. 'yellow') or hex value (e.g. '#ffff00'), with choice of UPPER or lower case (#158) -->
- Auto-generates standard wire color schemes and allows custom ones if needed
  - [DIN 47100](https://en.wikipedia.org/wiki/DIN_47100) (WT/BN/GN/YE/GY/PK/BU/RD/BK/VT/...)
  - [IEC 60757](https://en.wikipedia.org/wiki/Electronic_color_code#Color_band_system) (BN/RD/OR/YE/GN/BU/VT/GY/WT/BK/...)
  - [25 Pair Color Code](https://en.wikipedia.org/wiki/25-pair_color_code#Color_coding) (BUWH/WHBU/OGWH/WHOG/GNWH/WHGN/BNWH/...)
  - [TIA/EIA 568 A/B](https://en.wikipedia.org/wiki/TIA/EIA-568#Wiring) (Subset of 25-Pair, used in CAT-5/6/...)
- Understands wire gauge in mm² or AWG
  - Optionally auto-calculates equivalent gauge between mm² and AWG
- Is suitable for both very simple cables, and more complex harnesses.
- Allows for easy-autorouting for 1-to-1 wiring
- Generates BOM (Bill of Materials)

_Note_: Filare is not designed to represent the complete wiring of a system. Its main aim is to document the construction of individual wires and harnesses.

## Examples

### Demo 01

[Filare input file](../examples/demo01.yml):

```yaml
connectors:
  X1:
    type: D-Sub
    subtype: female
    pinlabels: [DCD, RX, TX, DTR, GND, DSR, RTS, CTS, RI]
  X2:
    type: Molex KK 254
    subtype: female
    pinlabels: [GND, RX, TX]

cables:
  W1:
    gauge: 0.25 mm2
    length: 0.2
    color_code: DIN
    wirecount: 3
    shield: true

connections:
  - - X1: [5, 2, 3]
    - W1: [1, 2, 3]
    - X2: [1, 3, 2]
  - - X1: 5
    - W1: s
```

Output file:

### Syntax, tutorial and example gallery

Read the [syntax description](syntax.md) to learn about Filare's features and how to use them.

See the [tutorial page](../tutorial/readme.md) for sample code, as well as the [example gallery](../examples/readme.md) to see more of what Filare can do.

## Installation

### Requirements

Filare requires Python 3.9 or later.

Filare requires GraphViz to be installed in order to work. See the [GraphViz download page](https://graphviz.org/download/) for OS-specific instructions.

_Note_: Ubuntu 18.04 LTS users in particular may need to separately install Python 3.7 or above, as that comes with Python 3.6 as the included system Python install. The option to generate pdf is not supported for python 3.7, so it might not be possible to use with this version of Ubuntu. If you are forced to use Ubuntu 18.04 for some reason, fill up an issue/MR and I can provide a Docker image to perform the generation.

#### Debian Dependencies

```
sudo apt install graphviz
```

#### Fedora Dependencies

```
sudo dnf install graphviz
```

#### Pango (only for weasyprint pdf generation)

See https://pango.gnome.org/

### Installing the latest release

~~The latest Filare release can be downloaded from [PyPI](https://pypi.org/project/filare/) with the following command:~~

```
pip3 install filare
```

Note: The https://github.com/laurierloi/Filare version sadly can't be downloaded from pypi at
this time. If you have this need, submit a MR and it could be added under a different name.

### Installing the development version

Access to the current state of the development branch can be gained by cloning the repo and installing manually.

We suggest always installing Filare within a python virtualenv. This avoids many issues caused by
dependencies management.

#### Installing Filare within a virtual env

```
# Cloning the repository
git clone git+https://github.com/laurierloi/Filare
cd Filare

# Setup virtualenv
python3 -m pip install --user virtualenv
python3 -m virtualenv venv-filare
source venv-filare/bin/activate

# Installing/Upgrading dependencies
pip install -U pip setuptools wheel

# Installing with local modification tracking
pip install -e .
```

If you would like to contribute to this project, make sure you read the [contribution guidelines](CONTRIBUTING.md)!

## Usage

### How to run

The Filare CLI (legacy `filare` alias still available) creates harness documents.
To do so, a shared metadata file (or multiple) must be provided to the `filare` command.
Then, a list of harnesses to include within the document should also be provided.
In the simplest case, 1 harness can be provided.

```
$ filare -d ~/path/to/file/metadata.yml ~/path/to/file/myharness1.yml ~/path/to/file/myharness2.yml
```

Depending on the options specified, this will output some or all of the following files:

```
titlepage.html            Titlepage document. It has links to the different harness for easy navigation
shared_bom.tsv            A BOM (bill of materials) for all items within the harness document
myharness{1,2}.gv         GraphViz output
myharness{1,2}.svg        Wiring diagram as vector image
myharness{1,2}.png        Wiring diagram as raster image
myharness{1,2}.bom.tsv    BOM (bill of materials) as tab-separated text file
myharness{1,2}.html       HTML page with wiring diagram and BOM embedded
```

Wildcars in the file path are also supported to process multiple files at once, e.g.:

```
$ filare ~/path/to/files/*.yml
```

To see how to specify the output formats, as well as additional options, run:

```
$ filare --help
```

#### Sample run all examples

```
$ filare -d examples/metadata.yml examples/ex*.yml
```

Then open `examples/titlepage.html` to open the document root

### (Re-)Building the example projects
