Frustration galore

[Bob Jansen]

I am hoping that someone can shine some light on my issue as I have been working at it for some hours now to no success.

The task is to create a tiddler storing in a field a string, for example, ArtworkImages/BJ007.jpg, where the number is an incremental number and the text comes from various tiddlers, eg. $:/TLS/imagefoldername,  so it can be altered as required..

My code is as follows
<code>

\define artworkurl() <<foldername>><<idcode>><<incremental>><<imagecode>>

\define uniqueid()<<idcode>><<incremental>>

<$set name=foldername value={{$:/TLS/imagefoldername}} >
<$set name=imagecode value={{$:/TLS/imagetypecode}} >
<$set name=newid value= <<uniqueid>> >
<$set name=theurl value=<<artworkurl>> >
<$set name=idcode value={{$:/TLS/idcode}} >
<$set name=incremental value={{$:/TLS/incremental}} >

''Artwork unique ID: <<newid>>''

-----

idcode <<idcode>>

incremental <<incremental>>

foldername <<foldername>>

imagecode <<imagecode>>

newid <<newid>>

theurl <<theurl>>

-----

Artwork title: <$edit-text tiddler="$:/TLS/new-title" tag="input" default=""/>

Type: <$edit-text tiddler="$:/TLS/artwork-type" tag="input" default=""/>

Medium: <$edit-text tiddler="$:/TLS/medium" tag="input" default=""/>

Size: <$edit-text tiddler="$:/TLS/size" tag="input" default=""/>

Year created: <$edit-text tiddler="$:/TLS/year-created" tag="input" default=""/>

Number in edition: <$edit-text tiddler="$:/TLS/number-in-edition" tag="input" default=""/>

---

Purchased by: <$edit-text tiddler="$:/TLS/purchased-by" tag="input" default=""/>

Date purchased: <$edit-text tiddler="$:/TLS/date-purchased" tag="input" default=""/>

Price: <$edit-text tiddler="$:/TLS/price" tag="input" default=""/>

<$action-deletetiddler $tiddler="$:/TLS/artwork-type" />
<$action-deletetiddler $tiddler="$:/TLS/artwork-submitted-to-exhibition" />
Add new artwork
</$button>

</code>

The problem is passing the values of  artwork_url and artwork_id into the new tiddler. The values stored are: artwork_id is <<idcode>><<incremental>> and artwork_url is <<foldername>><<idcode>><<incremental>><<imagecode>> instead of their values.

However, displaying the values of the variables  for debugging purposes gives:

idcode YB

incremental 20

foldername ArtworkImages/

imagecode .jpg

newid YB20

theurl ArtworkImages/YB20.jpg

These values are as they should be but they are not carried across into the action-createtiddler widget. 

I have tried passing the values through the local variables using for example, artwork_url=<<theurl>> or through a macro call artwork_url=<<artworkurl>> instead of  trying to get the value from the temporary tiddler artwork_url={{$:/TLS/artworkurl}} but nothing works.

What am I doing wrong?

Macros do ONLY two kinds of processing:

1) Replace any instances of $arg$ passed in

2) Replace any instances of $(variable)$ that are defined *outside* the macro

Everything else contained inside a macro is returned exactly as defined within the macro.  It is up to the "calling context" to process the returned macro content.

When you write:

\define artworkurl() <<foldername>><<idcode>><<incremental>><<imagecode>>
\define uniqueid() <<idcode>><<incremental>>

The results are to simply return the macro's contents as shown.  The variables references inside the macros are not automatically converted to their values.

If you then *display* the results of the macro, the "<<variablename>>" syntax is automatically "wikified" to render the value stored in the variable.

However, when you use the results of the macro as a *parameter* in a $widget, the macro results are passed to the $widget "as-is" without further processing.

The easiest way to make your code work (assuming no other problems) is to change these two macros, like this:

\define artworkurl() $(foldername)$$(idcode)$$(incremental)$$(imagecode)$
\define uniqueid() $(idcode)$$(incremental)$

By doing this, the content returned from those macros WILL be the *values* of the variables, not the references to the variables.

Thanks Eric, will give this a try. In an earlier version, I did use the $(..)$ format and then for a reason I can't explain, replaced it by the <<..>> format after reading various manual pages.
