Dear experts,
my observation is that font expansion and parshape don't (didn't) play well together, is that correct? I use a very old version of LuaTeX (0.79) and break the paragraph by calling tex.linebreak(). I also set f.stretch = 40 f.shrink = 30 f.step = 10 f.auto_expand = true on the fonts. When the parameter on the second option of tex.linebreak() has a parshape table, (left margin 0, right margin at max width, so the same margins etc. as the regular text) I get a different line break. My question is: is this intentional or is there something I can do on my side to prevent the different behavior? I can't provide a plain TeX test file yet, just an output of my software at https://github.com/speedata/publisher/issues/125 The first paragraph uses a parshape table. Patrick
