- *.ufo
- Font sources in UFO format, with files named according to their variation parameters.
- measurements.json
- Standalone JSON file containing definitions for various font- and glyph-level measurements.
Created using the Measurements tool from the VariableValues RoboFont extension.
See Measurements format for documentation of the data format. - blends.json
- Standalone JSON file containing definitions of blended axes and blended sources from parametric axes.
Used when building the avar2 designspace. - features
- Subfolder with .fea files containing OpenType feature code used by the source fonts.
- AmstelvarA2-Roman.glyphConstruction
- GlyphConstruction file containing instructions for building glyphs from components.
- AmstelvarA2-Roman.roboFontSets
- SmartSets file containing various sets of glyphs.
- AmstelvarA2-Roman_avar2.designspace
- Designspace for building the avar2 variable font.

A subfolder containing various scripts used during development. The most relevant ones are listed below.
- set-names-from-measurements.py
- Set file name and style name from measurements in all UFOs in a given folder.
Includes a preflight mode which only prints the new names without changing the files. - copy-glyphs.py
- Copy glyphs from the default font to selected sources.
- build-glyphs.py
- Build glyphs from glyph constructions in the selected sources.
- validate-locations.py
- Check if source locations are within the allowed min/max bounds for each axis.
Helpful when debugging calculated blend values in relation to the current parametric axes. - mark-components.py
- Mark glyphs in the current font containing components with different colors depending on their components' nesting level.
The appropriate values for blending opsz wght wdth from parametric axes are produced on a separate repository which is a fork of the original Amstelvar source. [The naming of UFO files was adjusted for easier parameter parsing (using underscores to separate parameters instead of hyphens), and all unnecessary files were deleted.]
A separate measurements file was added for Amstelvar, with the same parameters used for measuring AmstelvarA2. This file is needed because the contour structures of the two versions are different, and in most measurements different point indexes must be used.
Using this separate measurements file, the original Amstelvar sources are then measured to produce the blends.json file which is used by the AmstelvarA2 designspace builder.
