[JW Lua] SetPageSize script

[Charles O. Lawrence]

Jari, et al,

I have implemented a more "Lua-like" design as you suggest.  I like it much
better.  Thanks for the suggestion.  Please find attached rev 0.02.  It took
me some fiddling to get the right syntax to retrieve the table values within
a table, but it is similar to other programing languages I have used.  Is
there another syntax you suggest?  I sorted the popuplist table, since the
dropdown was not in the same order as the table was initialized.

Thanks,
Charles Lawrence

I looked at the general design of the script. A more "Lua-like" approach
would be to not separate name string and (in this case) page size. That
makes it easier to maintain, read and expand.

Also, finenv.UserValueInput supports that programming model, since each page
name string is unique in the table.

Test this this table-with-tables approach:
---
local selectPageSize = {["Letter (8.5 x 11)"] = {2448, 3168},
                         ["Legal (8.5 x 14)"] = {2448, 4032},
-- and so on and so on....
}  -- The end of the table
---

The "downside" is that you need to translate that to a string table for use
as the finenv.UserValueInput() list, such as:
---
local popuplist = {}
for key, value in pairs(selectPageSize) do
     table.insert(popuplist, key)  -- Using Lua's table library end
-- You might need to sort popuplist here as well, don't know...
---

For this example, use dialog:SetTypes("String") instead of "NumberedList"
and the selected string value will be returned in your returnValues[1] from
dialog:Execute(). The nice thing here is that you can use the selected
string directly as the key to page size.

The code in this mail is untested, but the concept should work.


Best regards,

Jari Williamsson
