Fixes:
* blank line at end of file
* closing bracket does not match indentation of opening bracket's line
* continuation line over-indented for hanging indent
* continuation line over-indented for visual indent
* continuation line unaligned for hanging indent
* inline comment should start with '# '
* missing whitespace around arithmetic operator
* missing whitespace around bitwise or shift operator
* multiple imports on one line
* multiple spaces after ':'
* multiple spaces after operator
The internal parameter names are just there to give an extra hint in the
source text for what the argument is. Consequently, we don't want to
allow filtering to match against them.
Parameters (to methods, initializers, accessors, subscripts, etc) have always been represented
as Pattern's (of a particular sort), stemming from an early design direction that was abandoned.
Being built on top of patterns leads to patterns being overly complicated (e.g. tuple patterns
have to have varargs and default parameters) and make working on parameter lists complicated
and error prone. This might have been ok in 2015, but there is no way we can live like this in
2016.
Instead of using Patterns, carve out a new ParameterList and Parameter type to represent all the
parameter specific stuff. This simplifies many things and allows a lot of simplifications.
Unfortunately, I wasn't able to do this very incrementally, so this is a huge patch. The good
news is that it erases a ton of code, and the technical debt that went with it. Ignoring test
suite changes, we have:
77 files changed, 2359 insertions(+), 3221 deletions(-)
This patch also makes a bunch of wierd things dead, but I'll sweep those out in follow-on
patches.
Fixes <rdar://problem/22846558> No code completions in Foo( when Foo has error type
Fixes <rdar://problem/24026538> Slight regression in generated header, which I filed to go with 3a23d75.
Fixes an overloading bug involving default arguments and curried functions (see the diff to
Constraints/diagnostics.swift, which we now correctly accept).
Fixes cases where problems with parameters would get emitted multiple times, e.g. in the
test/Parse/subscripting.swift testcase.
The source range for ParamDecl now includes its type, which permutes some of the IDE / SourceModel tests
(for the better, I think).
Eliminates the bogus "type annotation missing in pattern" error message when a type isn't
specified for a parameter (see test/decl/func/functions.swift).
This now consistently parenthesizes argument lists in function types, which leads to many diffs in the
SILGen tests among others.
This does break the "sibling indentation" test in SourceKit/CodeFormat/indent-sibling.swift, and
I haven't been able to figure it out. Given that this is experimental functionality anyway,
I'm just XFAILing the test for now. i'll look at it separately from this mongo diff.
This is necessary for some other work I'm doing, which really wants
paramdecls to have reasonable declcontexts. It is also a small step
towards generic subscripts.
Running the Python style guide checker
[`pep8`](https://pypi.python.org/pypi/pep8) on the Python code headers
in this repository results in the following error being emitted:
$ pep8 utils/build-script
utils/build-script:1:1: E265 block comment should start with '# '
utils/build-script:3:1: E266 too many leading '#' for block comment
utils/build-script:5:1: E266 too many leading '#' for block comment
utils/build-script:6:1: E266 too many leading '#' for block comment
utils/build-script:8:1: E266 too many leading '#' for block comment

utils/build-script:11:1: E265 block comment should start with '# '
utils/build-script:11:80: E501 line too long (80 > 79 characters)
The problem is that the code header used in most Python files in the
repository:
1. Do not place a space in between `#` and the rest of the comment.
2. Contains some lines that just barely exceed the recommend length
limit.
In addition, not all code headers in the repository follow the same
template.
This commit moves all Python code headers to the following template:

Follow-up to PR #655 as requested by @gribozavr
(libraries now)
It has been generally agreed that we need to do this reorg, and now
seems like the perfect time. Some major pass reorganization is in the
works.
This does not have to be the final word on the matter. The consensus
among those working on the code is that it's much better than what we
had and a better starting point for future bike shedding.
Note that the previous organization was designed to allow separate
analysis and optimization libraries. It turns out this is an
artificial distinction and not an important goal.
