Samples: GUI scripts for FontLab 9 106 single-file PythonQt dialogs for everyday font work: anchors, metrics,
kerning, outlines, masters, names, guides, font info, features, hinting, cleanup,
generators, reports and proofs. Each one works on the current font and offers a master
scope where that makes sense; most list what an Apply will change before you press it,
and a few (such as mark-colour swatches) apply on click. Report, browser and proof
scripts change no font data (some select glyphs, copy to the clipboard or export files).
Many glyph-editing tools group their edits into one Undo step, but Undo coverage varies.
Seven metrics scripts warn that moved stem hints are not restored, and font-wide data
(font info, OpenType features, master settings) is written directly: Italic Angle
(Masters) states that Undo does not restore its change. Read each script's notes before
applying changes.
Copy any file into FontLab's Scripts folder (for example Scripts/Samples) and run
it from the Scripts menu, or open it in the Scripting panel. A script needs only
FontLab 9 and its bundled PythonQt; nothing else is installed. Dialogs are modeless,
so the Font window stays usable, and every dialog disconnects its signals when closed.
Each script was run in FontLab 9.0.9783 through its menu path on disposable copies of
GetGo fonts, with screenshots and before/after reads of the changed glyphs. Edits on
glyphs used by automatic composites warn first: FontLab may rebuild those composites'
anchors and locks, and Undo does not restore that rebuild.
