I know how to create a new command or an environment. I think it will much better if I can specify name of the arguments. For example in framebox command and array environment below, we know exactly what're the arguments that should be passed.

\framebox(xdimen,ydimen)[position]{text}

\begin{array}[pos]{cols}
    content...
\end{array}

So far, I've tried

\documentclass{article}

\def\testdef#1#2{#1 #2}


\newcommand{\testcommand}[2]{#1 #2}


\newenvironment{testenv}[2]{#1}{#2}


\begin{document}


\testdef{arg1}{arg2}


\testcommand


\begin{testenv}{1}{2}
content...
\end{testenv}


\end{document}

and you all can see, \testdef{arg1}{arg2} just print arg1 and arg2 while I need to naming them with, for example, name and value. It should be

\testdef{name}{value}

The same goes also for \testcommand and testenv. So, How can I do that?

Edit

These pictures is taken from TeXstudio.

In picture #1, we see what are arguments for \framebox.

enter image description here

while in picture #2, we just see \testdef{arg1}{arg2}.

Is it behavior of Latex editor? or we can tune it through latex macro?

  • Your question isn't very clear but I think you are looking for a syntax like \testdef{arg1=value1, arg2=value2} in which case you should look at the keyval package (or extended versions such as xkeyval or l3keys) – David Carlisle May 07 '14 at 08:18
  • I don't really understad what you want. In case of \def you are just asking for two usual arguments {…}{…}, optionals are a bit more tricky. In \newcommand you are doing the same, you need \newcommand\testcommand[2][]{#1 #2} or something similar. And in the \newenvironment there is a problem, the arguments can only be used in the “opening”; usually in the \begin some variables are defined with the arguments, and then in the \end they are used. Again, you need \newenvironment{testenv}[2][]{…}{…}. Take a look at xparse. – Manuel May 07 '14 at 08:19

    In the documentation, something like \begin{array}[<pos>]{<cols>} uses <pos> and <cols> as place-holders to show what is going on, but in the code you still need #1, #2, etc. In TeX parameters have numbers, not names (you can work-around this in LuaTeX, but that I know of this has only been done in ConTeXt and not in LaTeX). – Joseph Wright May 07 '14 at 08:21

    Your edited question is just about the help prompts added by that editor, it is nothing to do with TeX at all, sorry I can't help as I don't use that editor. – David Carlisle May 07 '14 at 10:27

    TeXstudio stores the auto-completion data as a series of .cwl files: see e.g. http://tex.stackexchange.com/questions/79643/texstudio-does-not-recognize-colon/85220 for some discussion of altering/adding them. The thing is that this requires knowing what commands to add: are you looking to extend by a 'fixed' set of commands? – Joseph Wright May 07 '14 at 10:38

You have to create a .cwl file and manually activate in in Options -> completion. See the FAQ and the manual.
