[v3,17/21] Refactor suppression property string parsing.
Commit Message
This patch introduces a helper function to look up a key in an ini
configuration section and get a string value. All string look-ups now
use this.
There are no behavioural changes.

I would prefer a signature like
std::string get_string_prop(... section, ... name, std::string default = "");
In fact, this could be also
template<typename T>
T get_prop(... section, ... name, T default);
if prop->get_value() would be changed accordingly.
This does not play nicely with several keys to lookup though ...
Cheers,

maybe_get_string_prop and maybe_get_regex_prop were the obvious code
refactoring to do as there was a lot of repetition. From the
perspective of M commits later, they are the wrong choice.
In hindsight (!) I should have made a different choice as to how I
ordered my various changes. Something like this:
(this is for strings, something more involved for other types)
1. replace the code above with either
a) if a value is needed unconditionally (as a constructor argument)
string foo_str;
if (prop foo_prop = section.find_property("foo"))
read_string(foo_prop, foo_str);
b) or conditionally:
if (prop prop = section.find_property("foo")) {
string str;
if (read_string(prop, str))
suppression.set_foo(str);
}
also replacing code like this at the same time:
if (!foo_str.empty())
suppression.set_foo(str);
2. Make the suppression constructors all default
This would mean switching all the code using pattern a) above to pattern b).
Default values are set by the default constructor, rather than being
scattered about the code.
...
...
N. Replace the find_property calls (and the special scan for
"parameter" properties) with something table-driven.
I can rework the patch series from this point along these lines.
Before I launch into it, let me know what you think! Thanks.
