When defining the font at the T E X end we can now refer to for instance wide_all which
saves us some typing. However, it does not stop here. In a later paragraph we will see
how fonts can work in tandem with the parbuilder. For that purpose the goodie table
has a solutions subtable:
solutions = {
experimental = {
less = {
"shrink"
},
more = {
"minimal_stretching", "medium_stretching", "maximal_stretching", "wide_all"
},
},
}
Here we define an experimental solution for optimizing the lines in a paragraph: we
can narrow words or we can widen them according to a specific featureset. In order to
reach the optimal solution the text will be retypeset under a different feature regime.
Because there are a some 55 stylistic and 21 justification variants the goodie file
also provides a stylistics table and for tracing purposes the colorschemes table is
populated.
Yet another demonstration of manipulation is the following. Not all fonts come with all
combined glyphs. Although we have an auto-compose feature in ConT E Xt it sometimes
helps to be specific with respect to some combinations. This is where the compositions
goodie kicks in:
local compose = {
[0x1E02] = {
anchored = "top",
},
[0x1E04] = {
anchored = "bottom",
},
[0x0042] = { -- B
anchors = {
top = {
x = 300,
y = 700,
},
bottom = {
x = 300,
y = -30,
