PREAMBLE
The goals of the Open Font License (OFL) are to stimulate worldwide
development of collaborative font projects, to support the font creation
efforts of academic and linguistic communities, and to provide a free and
open framework in which fonts may be shared and improved in partnership
with others.
The OFL allows the licensed fonts to be used, studied, modified and
redistributed freely as long as they are not sold by themselves. The
fonts, including any derivative works, can be bundled, embedded,
redistributed and/or sold with any software provided that any reserved
names are not used by derivative works. The fonts and derivatives,
however, cannot be released under any other type of license. The
requirement for fonts to remain under this license does not apply
to any document created using the fonts or their derivatives.

# Geologica
Geologica is grounded in the humanist genre, but leans assertively into geometric, constructed letterforms to find its stability. The wide stance, generous spacing, large apertures and even colour makes Geologica a serious text typeface. The stylistic “Sharpness” axis adds a rational interpretation of calligraphic pen strokes – a modernist echo of the roots of writing.
The default style of the Geologica typeface is a sober humanist sans serif with a rational finish. The terminals are perpendicular to the direction of the pen stroke, emphasising the monolinearity of the letterforms. The alternate “Sharp” styles introduces details derived from writing with a broad-nib pen. Sharp points arise where the imagined pen is set to paper. These details are echoed in the Carthesian terminal treatment, causing curved shapes to form sharp inner points as they terminate.
Geologica uses the power of the OpenType Variable Font format to simultaneously morph between Light and Black weights, Upright and Oblique, and stylistic variants. This gives an incredibly rich typographic palette, making Geologica a typeface of great versatility.
### Variable axis
| Axes | Tag | Range | Default | Description |
| :------------ | :--- | :--------- | :------- | :----------------------------------------------------- |
| Cursive | CRSV | 0 - 1 | 0 | Swaps Roman for Cursive variants of certain characters |
| Sharp | SHRP | 0 to 100 | 0 | Detailing and terminal treatment |
| Weight | wght | 100 to 900 | 100 | Thin to Black |
| Slant | slnt | 0 to -12 | 0 | Upright (0°) to Oblique (-12°) |
# Building the fonts
## Step 1: Virtual environment & requirements
### Navigate to the root directory
```
cd [folder location]
```
### Set up a virtual environment in the root directory
```
virtualenv -p python3 venv
```
### Activate the virtual environment
```
source venv/bin/activate
```
### Install requirements
```
pip install -U -r Requirements.txt
```
You might also need to install ttfautohint
```
brew install ttfautohint
```
## Step 2: Build the fonts
### Navigate to /sources
Assuming you are already in the root directory
```
cd sources
```
### Build designspace file in /master_ufo
```
sh build_ds.sh
```
**Notes:**
- Run this command every time you make changes to the source file.
- Once you update the designspace, merge the contents of the `RulesFeatureVariations.txt` file with your .designspace file. See details in the txt file.
### Build OTvar and TTF fonts
```
gftools builder config.yaml
```
