Latex provides several commands relating to creating new commands such as newcommand. If I want to define new commands from a Lua script one way is use tex.print to write this directly into the document.



It this really the best way though? The whole point of LuaTeX is to avoid programming with Tex macros, yet this approaches involves doing exactly that. How can I directly access, edit and create commands directly from Lua?



script.lua



tex.print("\newcommand\helloHello world")


document.tex



documentclassarticle
begindocument
 directlua require("script") 
 hello
enddocument

  • LuaTeX is about combining Lua and TeX: if you look at ConTeXt, it is still a macro system using Lua _where it adds functionality

  • Accepted, thank you. Do you know of any good packages/classes on CTAN I could look at that are implemented in Lua and do this sort of thing? (To try to understand the common patterns a bit better. I'm looking at building a document class)

Long meetings (6-7 hours a day): Being “babysat” by supervisor

Clash Royale CLAN TAG #URR8PPP .everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty margin-bottom:0; up vote 31 down vote favorite 4 I hold a PhD in mechanical engineering with a 7 year background in self-guided, self-paced research including 2 years as a graduate level course instructor and a subject matter expert for various engineering projects in a university setting in the United States. For the last 10-11 months, I am working in a research industry in France where my task is to debug C++ spaghetti code written over a period of several years by my current supervisor. It is a team of 2: just I and my supervisor. Diurnally, I am posed with a "bug of the day" to get out of this C++ code. My supervisor generally gives me about 15-30 minutes to solve it and then accosts me about whether or not the task is completed and then rinses and repeats this until the end of the day.

Confectionery

Image
Prepared foods made with a lot of sugar or other cabohydrates "Sweetmeat" redirects here. For the racehorse, see Sweetmeat (horse). Not to be confused with Sweetbread. This Kransekake is a traditional Scandinavian baker's confection. Confectionery is the art of making confections , which are food items that are rich in sugar and carbohydrates. Exact definitions are difficult. [1] In general, though, confectionery is divided into two broad and somewhat overlapping categories, bakers' confections and sugar confections. [2] Bakers' confectionery, also called flour confections , includes principally sweet pastries, cakes, and similar baked goods. Sugar confectionery includes candies ( sweets in British English), candied nuts, chocolates, chewing gum, bubble gum, pastillage, and other confections that are made primarily of sugar. In some cases, chocolate confections (confections made of chocolate) are treated as a separate category, as are sugar-free versions of
