The new splitlines method on str is intended to replace usage of
fs.read('whatever').strip().split('\n').
The problem with the .strip().split() approach is that it doesn't have a
way to represent empty lists (an empty string becomes a list with one
empty string, not an empty list), and it doesn't handle Windows-style
line endings.
Compiled languages are Meson's bread and butter, but hardly required.
This is convenient, because many test caases specifically, do not care
about testing the compiler interactions.
In such cases, we can skip doing compiler lookups which aren't used, as
they only slow down test setup.
String formatting should validly assume that printing a list means
printing the list itself. Instead, something like this broke:
'one is: @0@ and two is: @1@'.format(['foo', 'bar'], ['baz'])
which would evaluate as:
'one is: foo and two is: bar'
or:
'the value of array option foobar is: @0@'.format(get_option('foobar'))
which should evaluate with '-Dfoobar=[]' as
'the value of array option foobar is: []'
But instead produced:
meson.build:7:0: ERROR: Format placeholder @0@ out of range.
Fixes#9530
This reverts commit c0efa7ab22.
This was a nice idea, or a beautiful hack depending on your perspective.
Unfortunately, it turns out to be a lot harder than we originally
thought. By operating on bare nodes, we end up triggering a FeatureNew
on anything that isn't a string literal, rather than anything that
isn't a string.
Since no one else has come up with a better idea for implementing a
FeatureNew, let's just revert it. Better to not have a warning, than
have it trigger way too often.
Another commit in my quest to rid InterpreterBase from all higher
level object processing logic.
Additionally, there is a a logic change here, since `str.join` now
uses varargs and can now accept more than one argument (and supports
list flattening).
