SID-00596: Include and Replace

Status:	Answered	TWiki version:	4.2.4	Perl version:	-
Category:	CategoryMissingFunctionality	Server OS:	Linux	Last update:	16 years ago

I want to INCLUDE a TWiki-Page and apply a substitution on the included text.

Example:

Text to on the page to include: "A|B|C". Text to appear on the page which includes the text: "A, B, C".

How can I do that?

Discussion and Answer

You can do that with the EXTRACT function of FilterPlugin. The official documentation is a bit sparse, so you might want to check out my reworking of its examples at TWikibug:Item6085.

Or include it into a SpreadSheetPlugin formula, such as %CALC{$FORMULA1($FORMULA2($FORMULA3(%INCLUDE{FooBar}%)))}%. Make sure the included page does not contain any newlines.

More at VarINCLUDE, VarCALC. Remotely related examples at DashboardWithDynamicTable, DashboardWithDynamicInclude.

Thanks! That solves my current problem. My example above was the wrong way around. Actually I need to translate "A, B, C" to "|A| |B| |C|". That could I do with the SpreadSheetPlugin.

But what if I had to do replacements on less structured input or what if the text contains newlines?

The INCLUDE variable supports the parameter "pattern". What about a parameter "replacement"? If specified every ouccurance of "pattern" would be replaced by "replacement". Wouldn't that a nice and helpful feature?

That would be a useful enhancement. You can file a feature request (link is sidebar). If you know Perl you could provide a patch - the fastest way to get a feature accepted.

I've tried to create a feature request, but I've no CHANGE permission for Codev. Neither with TWikiGuest nor with a new registered account. In my opinion to create a feature request should not require developer permissions.

Here is my feature request. I would glad, if somebody with developer permissions may enter it. If done, please set the status of this page to "Answered question" again. Thanks in advance.

ReplaceParameterForIncludeVariable

Introduce new parameter "replace" to INCLUDE variable

If you include a web-page to a TWiki page you possibly need to do some replacements, e.g. to remove superfluous or add missing html-code.

If you include a foreign page you can't use the existing parameter replacement mechanism (%PARONE%, %PARTWO%, ...).

The INCLUDE variable should be support one or more parameter pairs "patternN" and "replacementN". If specified every occurrence of "patternN" should be replaced by "replacementN". Replacement mode "text" oder "regex" should be selectable. That would by useful feature!
