Start tabular figures.

Tabular Figures.py

"""Create tabular figures. Version 0.1"""

"""
This script gives you a UI and some options for building tabular
figures. The generated glyphs contain duplicates of the source
glyphs, but their widths and sidebearings have been changed.
This does not attempt to squeeze or stretch the outlines, rather
it simply shifts them around.

-----------------------------------------------------------------

Groups List:
Groups of glyphs that should all have the same width.

The groups can have a fixed width, or the width for the group
can be created by averaging the width of all source glyphs in
the group. If you elect for a fixed width, you can enter it as
a set number of units (ie 250) or as a percentage (ie 50%).
Percentage values will be calculated as a percentage of the
overall tabular width.

Glyphs List:
List of glyphs in the selected group. The glyphs in this list
are the sources that will be used to generate the tabular glyphs.

-----------------------------------------------------------------

Use glyphs with suffix:
An optional suffix that will be appended to the source glyph
names when searching for source glyphs. For example, if you want
to generate old style tabular and your old style glyphs have a
".oldstyle" suffix, enter ".oldstyle" in this field.

Add suffix:
The sufix to be added to the tabular glyph names.

-----------------------------------------------------------------

Overwrite existing glyphs:
Enabling this will cause any glyphs with the same name as the
new tabular figures to be overwritten.

-----------------------------------------------------------------

Width:
The width for the tabular glyphs.

-----------------------------------------------------------------

Apply to all open fonts:
Enabling tis will add the tabular glyphs to all open fonts.

Apply to current font:
Enabling this will add the tabular glyphs only to the current font.

-----------------------------------------------------------------

Calculator
This is a simple dialog that averages the widths of selected
glyphs in specified fonts.

Thank you for sharing this. I was checking this out and I realised I don't have dialogKit. Is this a built in package in RF?

I think Frederik removed dialogKit from the latest RF beta. It was a very old UI toolkit that worked in FontLab that I made a vanilla version of so that old scripts could work in RF. Here's the old vanilla wrapper:

https://github.com/typesupply/dialogKit/blob/master/Lib/dialogKit/_dkVanilla.py

You should be able to convert everything to vanilla except ModalDialog. Just make that a Window.

Ideally this tool would be updated to ezui. :)
