Just a short post to share an example of producing clock faces with Arabic numbers using LuaTeX’s nodes and glue. No drawing packages were used, all done with pdf_literal nodes and some basic trigonometry to calculate positions of the numbers,…
It has been a long time since I wrote a blog post so I thought I’d share a rather nice “trick” I discovered today. You can pass a Lua table from a TeX macro to Lua. Here’s how. The result…
Just a short post to share another example from my on-going work on HarfBuzz A rather pointless example – without using any code to correctly place mark glyphs (e.g., vowels) – showing randomly coloured Arabic glyphs. Thanks to the power…
Building on the work of porting LuaTeX to build on Windows I decided to explore adding HarfBuzz to provide Arabic shaping. The excellent HarfBuzz API lends itself to some interesting solutions so here’s a quick post to show some early…
If you are interested to explore the inner structures of TeX boxes created in LuaTeX you can do this very conveniently using the following free resources: viznodelist.lua by Patrick Gundlach. This is an excellent Lua script that generates a text…
Well, today I finally achieved my ambition to build LuaTeX using Visual Studio. It took me about 25 hours of my evenings to do it but at long last I can now step through the code with a nice visual…
