SID-00286: Get substr of a variable like $topic

Status:	Answered	TWiki version:	4.0.5	Perl version:	5
Category:	CategorySearch	Server OS:	SunOs	Last update:	16 years ago

Hello, In our documentation, we use topics that share a common abbreviation at the beginning of the topic name:

e.g. MyServiceMain, MyServiceOrganization, MyServiceTroubleshooting, ...

In a %SEARCH operation, I can use the variable $topic, or extract a regular expression from its text, but I cannot extract a part of the $topic (in this case MyService).

The goal is to build for our services, a table having as column, name, organisation, troubleshooting, ... and as line, the services. The cells are links to the specialized topics.

Thanks. JM

Discussion and Answer

You can use some SpreadSheetPlugin formulae to extract part of $topic. To give an idea, use format="$percntCALC{$SET(base, $SUBSTITUTE(..., $topic))}$percnt", and then use $GET(base) to get the base name.

Consider sharing with the TWiki community your SEARCH with CALC if you find it.
