Using defmacro badly...

markbeck

Greetings all,

I'm trying to do something which I suspect may not be possible, but I figured I should ask.

I wish to create a macro that allows the user to write the contents of the @rest into a file.

e.g.

MyFileMacro( This is what I want to be written to a file)

I found that if I defined the following macro, I can get close:

(defmacro MyFileMacro (@rest body)
    sprintf(t_body "%L" `,body)
    `FunToWriteOutFile(,t_body)
)

This sorta works, but I have to clean up what is sent to `,body before writing it out to a file. `,body appears to be a bunch of function strings and so I end up with lots of '(' and ')' characters.

The issue I'm encountering is when the user enters in characters that are interpreted as a badly formed macro call...

e.g. MyFileMacro( blah{blah} )

This gives me a syntax error since skill is trying to interpret the contents of body before sending it to `,body.

 Basic question:

Is there a way to force the @rest body contents to be identically returned without any interpretation, such that I can then shove it into a string, or just get it to always interpret it as a string?

 Thanks,
Mark

     Ya, I suspected that this was the case. 

    From a programmer's standpoint, it's easier to deal with strings, however from a user's standpoint, if they have to write out something to a text file that needs quote characters they have to escape them..

    e.g. 

    If I wanted to write out:  The "cat" in the "hat"

    I would have to enter the string as:  "The \\"cat\\" in the \\"hat\\""

    It makes it a bit harder to read the contents...

     Thanks,
    Mark
