Is there a flag or option to ask Template Toolkit to evaluate all of the variables passed to it *first*, before it does anything else?
Since that sounds like an odd request, klet me explain what I'm doing... I'm using template toolkit to display a table. 1) I have an array of strings, which are column names. 2) I have an array of hashes that will contain the body of the table. The key to the hashes in (1) is the column names (2) The function that populates the body (2) sparsely populates the array of hashes (2), then checks for any columns which are completely empty. If a column is empty, I remove the column name from the array of column names (1) (because I don't want TT to display empty columns. I pass to TT: - A reference to the array of column names (1) - A reference to the function that builds the body (2) In the template, use the array (1) to build the table header of column names, then I use the array (1) to key into the array of hashes (2) to build the table body. Finaly I use the array again to build a table footer. The problem is that the array of hashes(2) isn't evaluated until it's needed. Since a side-effect of evaluating the array of hashes is to splice lumps out of the array of column names, I find that my header has the original, complete list of all possible column names, while the body and footer only includes the columns actualy required. Now, I can work round this by making a dummy reference to the body early on in my template, but this seems very ugly, so again my question: Is there a flag or option to ask Template Toolkit to evaluate all of the variables passed to it *first*, before it does anything else? _______________________________________________ templates mailing list [EMAIL PROTECTED] http://lists.ourshack.com/mailman/listinfo/templates
