# Most glyphs we want to maximize during the scale. However, there are some
# that need to be small or stay relative in size to each other.
# The following list are those glyphs. A tuple represents a range.
# Most glyphs we want to maximize (individually) during the scale
# However, there are some that need to be small or stay relative in
# size to each other.
# The glyph-specific behavior can be given as ScaleRules in the patch-set.
#
# ScaleRules can contain two different kind of rules (possibly in parallel):
# - ScaleGlyph:
# Here one specific glyph is used as 'scale blueprint'. Other glyphs are
# scaled by the same factor as this glyph. This is useful if you have one
# 'biggest' glyph and all others should stay relatively in size.
# Shifting in addition to scaling can be selected too (see below).
# - ScaleGroups:
# Here you specify a group of glyphs that should be handled together
# with the same scaling and shifting. The basis for it is a 'combined
# bounding box' of all glyphs in that group. All glyphs are handled as
# if they fill that combined bounding box.
#
# The ScaleGlyph method: You set 'ScaleGlyph' to the unicode of the reference glyph.
# Note that there can be only one per patch-set.
# Additionally you set 'GlyphsToScale' that contains all the glyphs that shall be
# handled (scaled) like the reference glyph.
# It is a List of: ((glyph code) or (tuple of two glyph codes that form a closed range))
# 'GlyphsToScale': [
# 0x0100, 0x0300, 0x0400, # The single glyphs 0x0100, 0x0300, and 0x0400
# (0x0200, 0x0210), # All glyphs 0x0200 to 0x0210 including both 0x0200 and 0x0210
# ]}
# If you want to not only scale but also shift as the refenerce glyph you give the
# data as 'GlyphsToScale+'. Note that only one set is used and the plus version is preferred.
#
# For the ScaleGroup method you define any number groups of glyphs and each group is
# handled separately. The combined bounding box of all glyphs in the group is determined
# and based on that the scale and shift for all the glyphs in the group.
# You define the groups as value of 'ScaleGroups'.
# It is a List of: ((lists of glyph codes) or (ranges of glyph codes))
# 'ScaleGroups': [
# [0x0100, 0x0300, 0x0400], # One group consists of glyphs 0x0100, 0x0300, and 0x0400
# range(0x0200, 0x0210 + 1), # Another group contains glyphs 0x0200 to 0x0210 incl.
#
# Note the subtle differences: tuple vs. range; closed vs open range; etc
# See prepareScaleRules() for some more details.
# For historic reasons ScaleGroups is sometimes called 'new method' and ScaleGlyph 'old'.

## Contents
This folder contains the source for the (current) Material Design Icons.
Source is https://github.com/Templarian/MaterialDesign-Font
Last fetch date is Oct 6, 2022.
After fetching a new file one needs to correct our cheat-sheet by updating `bin/scripts/lib/i_md.sh`.
Use the tool:
```
cd bin/scripts
mv lib/i_md.sh lib/i_md.sh_
python3 generate-glyph-info-from-set.py --start f0001 -end f1af0 -font ../../src/glyphs/materialdesign/MaterialDesignIconsDesktop.ttf -offset 0 -prefix md > lib/i_md.sh
```
Open old and new definitions shell script and copy the header from the old file to the autogenerated file. Adapt the values in the new file's header. Remove the last line in the new file (it contains the number of glyphs that is needed for the updated header). Yes, that is some manual labor.
## Source bugs fixed
Glyph 0xF1522 is broken in the original font. We fixed that one glyph manually.
See https://github.com/Templarian/MaterialDesign-Font/issues/9
