FPGA Oberon - Definition Module Tool
by thomas.kral＠email.cz 08 Oct '18

08 Oct '18

Hi, I am thinking of a simple tool that could extract definition info from *.Mod and produce respective *.Def file. Definition files can be quickly looked at, to remind a programmer of the interface *.Mod modules export. While on Linux one could use grep $ grep PROCEDURE\ * *.Mod.txt to obtain info at least about procedures, but how about exported types and variables? I am looking for a recommended way how to simply code such a tool, is it a good idea to use `ORP' parser somehow for the task? I prefer to code it simple, does not have to be perfect, but should carry the idea. Tomas

Mail.CutLines vs. Wrap

The old Mail module now has a command, Wrap, visible here. https://en.wikibooks.org/wiki/Oberon/Oberon.Mail.Mod#Wrap The rationale is here. https://en.wikibooks.org/wiki/Talk:Oberon/Oberon.Mail.Mod Suggestions to improve the algorithm or implementation are welcome. Thanks, ...

That suggests "font-family: sans-serif" or "font-family: sans-serif, serif". Also, many or most readers won't notice the differences between the various sans fonts.

font-family for a source.

These books are the two best typeset Oberon > books there are (imho). My copies aren't at hand. Those sources are set in a serif font? Times or similar? Web authorities claim that sans-serif is better for a small display. If the style tag in MediaWiki.Mod doesn't specify the font-family, Wikimedia will produce a monospaced text. To avoid that I think of "font-family: varispaced" but no such thing in the CSS spec. The closest choices are serif and sans-serif. Rather than impose one of these I can set "font-family: serif, sans-serif". Is there a better answer? Thanks, ...
