Converting them to pointers for Scheme to use. Prevents
dangling pointers when the user deletes a QofInstance as long as the
Scheme report code re-fetches its pointers from the options when it's
regenerated.
And use serialize to create values for gnc:generate-restore-forms and both
of them for the meat of the stream functions.
This fixes in particular QofInstance serialization where passing the
option value directly to scheme format resulted in a notation about
a swig pointer instead of the desired GUID string or commodity namespace
and mnemonic strings.
From a Scheme alist. The vector can be used to find the scheme symbol
as a direct lookup, which isn't possible with an alist, and can be
searched for the Scheme symbol match more quickly than an alist can.
Instead of arbitrarily using the first allowed value.
Also update tests for the Scheme type addition to
GncMultichoiceOptionChoices, intercept more cases where the value
needs to be transformed, and go back to emitting a string instead of
throwing in GncOptionMultichoiceValue::get_value when m_values has more
than one value.
Wraps creating a GncOptionDBPtr, freeing up gnc_option_db_new() to
return a GncOptionDB* for use in C code. Convert gnc_option_db_new()
calls in gtest-gnc-optiondb to call std::make_unique() as well.
Provides find_option(const char*) and foreach_option(func) for easy
iteration. find_option and find_section now return plain const ptrs
instead of std::optionals. Much less cumbersome though the compiler
won't nag if you forget the nullptr check.
To support a variation available in dialog-options. Even though it's not
used in any GnuCash code nor documented anywhere it might be in some
custom reports.
After getting a better understanding of how it interacts with dialog-options and
finding some additional scheme API needing implementation (exposed only in
hello-world.scm, but possibly used in user-written reports).
Creates a new file-pair, gnc-options-date.[ch]pp to separate the creation of
the static structs with the type info and strings for the various
RelativeDatePeriod values from the already too large gnc-option-impl.
Although the result is a rather C-ish design the alternative with classes
or template specializations would be more complicated and offer no
benefit.
Implements the permissible_values functions of GncOptionMultichoiceValue
for GncDateValue and provides for absolute, relative, and both
UI values for the three widget configs afforded by dialog-options.
Separating the UI from the data model. Note that the GncOptionVariant
classes still have a GncOptionUIType member to ensure that a
GncOptionUIItem of the right type is attached.
Not everything from the 6 Book-Currency commits is removed: Switching
the Num and split-action fields and restricting edits of transactions
older than n days were included and those changes are left in place.
Some other partly-implemented features were also part of these commits
and were removed: Options for setting a default capital gains account
and currency, completion of the LIFO cap-gains policy, and creation of
a list of cap-gains policies.
If any of these are to be revived they should each be done in a separate
feature branch and submitted via Github pull request for a code review
before merging; a design discussion on gnucash-devel before restarting
work is also advisable.
So only GncOption and the GncOptionDB free-function interface are public.
We don't want to expose template headers widely, it would blow up compilation
times and might lead to one definition rule violations.
