Version 1.2.3

• Update: Chain Variables: Add option to loop over all books per var in the table.
• Update: Chain Variables: Right clicking value cell opens template editor.
• Update: Add new template function book_vars to access book specific variables set by custom actions (using chain_loop.set_book_vars). They are no longer accessible from the globals template function, to provide consistent behaviour that enables set_globals to work the same everywhere.
• Fix: Formulas: Bug with mean value when fed an empty list or a list with no numerical values. It now handles it by returning 0.

Version 1.2.4

• Update: Selection Modifier: Add two new options: "Clear Selections", "Select first book in current view"
• Update: Add new template function set_book_vars.
• Update: Chain Variables: Guarantee order of processing of variables is same as order in table.
• Update: Chain Variables: Double clicking value cell will open template dialog if value start with "program:"

Version 1.3.0

• Update: Add new template function: category_items().
• Update: Chain Variables: Double clicking the value cell always opens the formula dialog.
• Fix: from_selection() and from_search() formulas always return a constant list of 1,2,3,4,5 when in any template dialog, not just in the formula dialog.

This is how to use the new category_items() template function:

program:
    category_items('#genre')

This would return all the #genre tags. You can replace #genre with any other category like tags, authors .... etc

It can also take second optional arg to limit the result to set of book_ids

program:
    book_ids = from_selection('id');
    category_items('#genre',book_ids)

from_selection() can be replaced with from_search() to achieve the same result.

The resulting items are separated by one of the following characters(s):

1. If the category contains names like the author field, the items are separated with ' & '.
2. If the category is a field that accepts multiple items like tag, the items are separated with ', '
3. If the category is a field that only accepts one value like series, the items are separated with ' ::: '. This is necessary because fields like series can contain commas AND/OR ampersands.

Also note that the previously intoduced book_vars() template function is now used to access book specific variables, instead of the old way of accessing them using the globals function. The both work differently; book_vars() requires you to pass an expression that is usually a constant string. The globals() function require that the arguments be variable names. This can be illustrated by the following examples:

program:
    globals(my_var)

program:
    book_vars('my_var')
