Hi all,
I am currently working on the integration of the Atlas plugin into the core.
I noticed the "replaceDateText" method of the QgsComposerLabel class
that is aimed at dealing with the very specific "$CURRENT_DATE"
expression and replace it with ... the current date.
For the sake of homogeneity and considering we have a powerful way of
handling expressions, why not consider text in labels where expressions
are surrounded by '[%' and '%]'. So $CURRENT_DATE would be replaced by
date manipulations based on '[% $now %]' ?
The other change I propose is to enhance the optional "substitution map"
that can be set on an expression text. It is used to define special
column names like $layerid, $CWD and so on when using Actions on a
layer. Until now, they are used for text replacement and cannot be used
within an expression.
My proposal is to make them first-class citizen within the grammar.
I have a local branch with these proposed changes. If there is no
special objections, I am about to propose them.
