Loop?

Loop?

[Angel M Alganza]

Hello:

I am trying to print a list of names always followed by the same info
(generated by a new command).  At the moment, I have all the names
followed by the command like so:

	Person Number One
	\mycommand
	Person Number Two
	\mycommand
	Person Number Three
	\mycommand
	Person Number Four
	\mycommand
	Person Number Five
	\mycommand
	.
	.
	.

I'd rather have the list of people stored somewhere (a list? an array?)
and loop through it and then inserting \mynewcommand at compilation
time.  That way, when I need to replace the list of people with a new
one, I'd just do that instead of building the above structure again and
again.

Is it possible to do that with just ConTeXt or would I need to resort to
Lua.  I guess it should be possible both ways, but I haven't figure out
how to do it.  Any pointer, please?

Thank you so much in advance.

Cheers,
Ángel

which wasn't particularly difficult to find.

Hi, Ángel. Like this?

\def\mylist{Fulano,Mengano,Sutano}

\def\mycommand#1{#1\blank{\red Something here}\blank}

\starttext

\processcommacommand[\mylist]\mycommand

\stoptext

There are better ways to deal with data in ConTeXt, but it's basically that
way, I think.

You can use the commalist environment:

\starttext

\startprocesscommalist[One,Two,Three,Four]
     Person Number \currentcommalistitem\par
\stopprocesscommalist

\blank

\defineexpandable\NameList{One,Two,Three,Four}

\startprocesscommacommand[\NameList]
     Person Number \currentcommalistitem\par
\stopprocesscommacommand

\stoptext


Another way is to use the database module:

\usemodule[database]

\starttext

\defineseparatedlist
   [namelist]
   [command=\NameEntry]

\starttexdefinition unexpanded NameEntry #1
     Person Number #1\par
\stoptexdefinition

\startseparatedlist[namelist]
One
Two
Three
Four
\stopseparatedlist

\stoptext

Oh, I knew about the environment form, but I didn't know about
\currentcommalistitem. Useful to avoid to define ad hoc commands :)
As always, thank you very much for the lesson.

Best regards,

Jairo

Yes, exactly like this, thank you.  Now, I have the names writen like:

	Family Name, Name

So, is it possible to use a list separatd by something else than a
comma?  A semicolon, for example?  To test I've replaced those commas by
a colon and it works fine, but I'd rather have a comma, if possible.

Again, thank you so much!

Cheers,
Ángel

There's \processseparatedlist[<list>][<separator>]\command with an
arbitrary <separator> other than a comma...

You should take a look at syst-aux.mkiv and syst-aux.mkxl to see more
helpers:

Thank you so much, Jairo and Wolfgang.
All your solutions work fine!

I had been looking for info on loops and some other ideas for a few days
already.  I never thought about "lists".   :-)

Below is another version.

Using the \startsetups block to set the content for the loop/list makes 
it easier to strucuture (format) the text. With \recursestring you can 
print the value of the current loop entry.

The list of entries for the loop can be moved from the argument itself 
to a macro. To make adding and removing (can be done by commenting 
entries with %) you can use the \starttexdefinition environment with 
each name on a separate line.

%%%% begin example
\starttext

\startsetups [NameEntry]
     Person Number \recursestring\par
\stopsetups

\doloopoverlist{One,Two,Three,Four}{\directsetup{NameEntry}}

\blank

%\defineexpandable\NameList
%  {One,
%   Two,
%   Three,
%   Four}

\starttexdefinition NameList
     One,
     Two,
     Three,
     Four
\stoptexdefinition

\doloopoverlist{\NameList}{\directsetup{NameEntry}}

\stoptext
%%%% end example

Very nice and easy to maintain the list of names.

Thank you so much!

You have to wikify all the answers ... here's another one:

\doloopovermatch {([^\letterpercent s,]+)} {aa, bb, cc, dd} {/#1/}

or more complex matching:

\doloopovermatch {(\letterpercent w+) *(\letterpercent w*)} {aa bb cc dd} {
     [
     \doloopovermatch{(\letterpercent w)(\letterpercent w)} {#1} {(##1 ##2)}
     \doloopovermatch{(\letterpercent w)(\letterpercent w)} {#2} {(##1 ##2)}
     ]
}
