From std::string. The consumer is a GtkWidget so we might as well do the conversion
inside the class and this will simplify adding these functions to GncOptionDateValue
in the next commit.
Implemented in gnc-optiondb.i it more clearly indicates the intended
use and restricts the access. Unfortunately further limiting the
friend declaration with #ifdef SWIG prevented the declaration from
working, raising the error "m_option is a private member of GncOption".
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.
Under some build conditions boost::typeindex will use an internal type
identifier that's different from the C++ builtin. In that case type equality
tests to C++ typeid in boost::variant will fail, breaking it. Using
boost::typeindex::type_id ensures that the comparisons always work.
These add or parse the textual noise needed to replicate the Scheme options'
serialization technique of saving scheme forms for saving report options
and then evaluating those forms to restore the option values. Required for
backward saved-reports compatibility.
Added advantage that it handles (not correctly, but in the same way as
the old code) the ambiguity between a period starting or ending with
the stored value "relative . today".
The old gnc:lookup-option returned the option object so that it could be
manipulated rather than getting its value; gnc_option_value replicates
the behavior of (gnc:option-value (gnc:lookup-option)).
