macro and submacro (private macro not available globally)

[Mohammad]

Hi

 I have a tiddler tagged with $:/tags/Macro in that I have three macros, tow of them work as sub-macro (like sub-function or private methods in other programming language) for the main macro.

• Example

\define smac1(a)  This is $a$

\define smac2(b)  and I it is really $b$.

\define myMac(x,y)

<<smac1 $x$>> <<smac2 $y$>>

\end

I use it like 

<<myMac "TW" "lovely">>

The question is I want to have only myMac available globally and not smac1, and smac2. Is it possible with TW?

Sure. Just put the first two macros in a tiddler labeled with $:/tags/Macro. Then don't put a macro in your 2nd tiddler that has the 3rd macro. e.g:

title: My Invocation tiddler
tags: RandomTag

\define myMac(x,y)
<<smac1 $x$>> <<smac2 $y$>>
\end

<<myMac "TW" "lovely">>

-- Mark

Mark!

Thank you for your quick reply!

The case is how can I have myMac available globally (can be invoked from any tiddlers) but smac1 and smac2 remain private!

1) put myMac() in a tiddler tagged with $:/tags/Macro

2) put smac1() and smac2() in another tiddler (e.g., "smacFunctions") tagged with "MyMacroFunctions"

in the definition of myMac(), write:

\define myMac(x,y)
<$importvariables filter="[tag[MyMacroFunctions]]">
<<smac1 $x$>> <<smac2 $y$>>
</$importvariables>
\end

The <$importvariables> widget pulls in all the variables (i.e., macro definitions) contained in the tiddlers matching the specified filter.

Note that, if you only want to include variables from one specific tiddler, then you don't need to use a tag... you can just specify the name of the tiddler as the filter:

<$importvariables filter="smacFunctions">

enjoy,

Hi Eric,

 Yes, that works wonderful! In this way I can hide the macros I don't want to be accessible by other tiddlers or globally.

Some times we create a code contains several parts, but only one macro should be available.

Note:

I use the  TW 5.1.18-prerelease, it seems instead of $includevariables I have to use $importvariables

Thank again Eric.

Cheers

Mohammad

You are great Eric!

Thank you!

Hi Mohammad,

If I test your example at tiddlywiki.com  I have global access to all 3 macros. ...

For me it seems you messed something up with your theme, or plugins.

uups, I didn't see the "not" in the request. ... So just ignore my post :)
