Forgive for top posting.
Put simply, as a module maker I would prefer if osis2mod would simply
Osis2mod should identify chunks of text and put them into the right
places and then be done - as little transformation as possible.
At that point it would allow us to do following things
1) Define a standard markup which will work/should work and not working
would become a filter/frontend bug
2) Create clean module making tools which create a visible and well
The black box of osis2mod which creates a format which can only be
interrogated with tools with a large number of further layers (filters
etc) with any number of intervening bugs makes the whole thing so
If we had a clear input format - this is how a CrossWire OSIS text
should look like - we could create the tools which create this very OSIS
text, subject it to XML validation, mess around with it and tell any
frontend author "This is what you do wrong!" - with exact and pinpoint
The complexity of the purposes of osis2mod is what makes it so
A tool should do one thing and do it well - not a multiplicity of things
at the same time in a half-arsed way.
So, if we want to automatise BSP->BSP conversion and preverse reordering
then the output should not be a module but another OSIS text.
The final, ideal OSIS2mod should take a defined format and create a
module, but baulk at nonstandard formats with a clear error message.
Re Troy's suggestion re improved tests - it stunned me as a suggestion
hence I had no response. Sure, we need this, but right now the situation
is so complicated with multiple interfering layers, that we do not even
know what we test. And osis2mod in its current form is the one
interfering layer too much.
So, my proposal - cut osis2mod into half. Let one part handle reordering
but then spit the result out as a new osis file. Which can be tested,
which can be worked upon.
And let the other part do the defined format to module transform,
without any further transformations. And whine if something is not to
