Injecting the result or a macro into another macro. (At least I think that's what i'm trying to do)

[Stephen Wilson]

Ok.

I'm using the mathcell plugin/ macro to generate a random number between 1 and 10

<$macrocall $name="eval1" datatiddler="Data" cell="Random"/>

The cell contains the following javascript 

=Math.floor((Math.random() * 10) + 1);

I need the result of this to be called into the following:

\define mylatex(a,b)
<$latex text="{$a$}+{$b$}" displayMode="true"></$latex>
\end
<$macrocall $name="mylatex" a={{!!Random}} b={{!!Random}}

Do I need to set a and b as macrocall eval1 in the define section or is there a way to place the output of eval1 into the space currently occupied by {{!!Random}} and is there a beter way to get a random number?

Cheers

I'm not familiar with the latex plugin, so I don't know if your mylatex macro is set up correctly. Assuming that it is, then I think you need to invoke it like:

<$macrocall $name="mylatex" a=<<eval1 datatiddler:"Data" cell:"Random">>  b=<<eval1 datatiddler:"Data" cell:"Random">>  >

Good luck!

Hi Mark,

Thanks for the help.

Unfortunately that returns 

<$latex text="{7}+{1}" displayMode="true"></$latex>

in the view pane.  Transcluding from another tiddler yields similar results and putting the eval in a field and transcluding from there, the same.

I had already tried your solution but assumed the fault was mine, so it's nice to know it wasn't just me :)

Back to the drawing board,

Stephen

You're going to need a recent version of TW5. Then define your macro like this:

\define mylatex(a,b)
<$wikify name="doit" text="""
<$latex text="{$a$}+{$b$}" displayMode="true"></$latex>""" >
<<doit>>
</$wikify>
\end

Worked on my set-up.

Good luck!
Mark

Wow...

Right...now to have a tinker and find the next road block.

Thank you.
