Daniel Jasper d9d8da2821 clang-format: [JS] Allow top-level conditionals again.
I am not sure exactly which test breakage Martin was trying to fix in
r273694. For now, fix the behavior for top-level conditionals, which
(surprisingly) are actually used somewhat commonly.

Eric Liu 4f8d99433d Make tooling::applyAllReplacements return llvm::Expected<string> instead of empty string to indicate potential error.
Summary:
return llvm::Expected<> to carry error status and error information.
This is the first step towards introducing "Error" into tooling::Replacements.

Martin Probst 2a19454a86 clang-format: [JS] Sort imports case insensitive.
Summary: ASCII case sorting does not help finding imported symbols quickly, and it is common to have e.g. class Foo and function fooFactory exported/imported from the same file.

This also applies to variable declarations, e.g.:

"const int* a" instead) and contracting to "const*" might actually send
the wrong signal of what the const binds to.

Martin Probst 6f43efbdde clang-format: [JS] fix an assertion failure caused by shrinking sources.
Summary:
The JavaScript import sorter has a corner condition that can cause the overall
source text length to shrink. This change circumvents the issue by appending
trailing space in the line after the import blocks to match at least the
previous source code length.

This needs a better long term fix, but this fixes the immediate issue.

To keep JS import sorting out of Format.cpp, this required extracting the

Eric Liu 6b47faad53 Revert "Added support for different VFSs in format::getStyle."
This reverts commit r264253. It is breaking the buildbot http://lab.llvm.org:8011/builders/llvm-clang-lld-x86_64-scei-ps4-windows10pro-fast/builds/2203

2016-03-24 11:25:28 +00:00
Eric Liu b72f6098df Added support for different VFSs in format::getStyle.
Summary:
Previously, format::getStyle assumes that the given file resides in
the real file system, which prevents the use of virtual file system in testing etc.
This patch adds a parameter in format::getStyle interface so that users can specify
the right file system. By default, the file system is the real file system.

Daniel Jasper 8fc7a1e992 clang-format: [JS] do not wrap ES6 imports/exports.
"import ... from '...';" and "export ... from '...';" should be treated
the same as goog.require/provide/module/forwardDeclare calls.

Daniel Jasper 91b1d1ab6c clang-format: [JS] no space in union and intersection types.
The operators | and & in types, as opposed to the bitwise operators,
should not have whitespace around them (e.g. `Foo<Bar|Baz>`).

Daniel Jasper 9c8ff3551a clang-format: Make include sorting's main include detection configurable.
This patch adds a regular expression to configure suffixes of an
included file to check whether it is the "main" include of the current
file. Previously, clang-format has allowed arbitrary suffixes on the
formatted file, which is still the case when no IncludeMainRegex is
specified.

Daniel Jasper 710f8493c8 clang-format: Slightly weaken AlignAfterOpenBracket=AlwaysBreak.
If a call takes a single argument, using AlwaysBreak can lead to lots
of wasted lines and additional indentation without improving the
readability in a significant way.

Before:
  caaaaaaaaaaaall(
      caaaaaaaaaaaall(
          caaaaaaaaaaaall(
              caaaaaaaaaaaaaaaaaaaaaaall(aaaaaaaaaaaaaa, aaaaaaaaa))));

Daniel Jasper 1dcbbcfc5c clang-format: [JS] Handle certain cases of ASI.
Automatic Semicolon Insertion can only be properly handled by parsing
source code. However conservatively catching just a few, common
situations prevents breaking code during development, which greatly
improves usability.

JS code should still use semicolons, and ASI code should be flagged by
a compiler or linter.

Daniel Jasper abd1f57453 clang-format: [JS] Optionally re-quote string literals.
Turns "foo" into 'foo' (or vice versa, depending on configuration).
This makes it more convenient to follow the Google JavaScript style
guide:
https://google.github.io/styleguide/javascriptguide.xml?showone=Strings#Strings

This functionality is behind the option "JavaScriptQuotes", which can be:

  * "leave" (no re-quoting)
  * "single" (change to single quotes)
  * "double" (change to double quotes)

This also changes single quoted JavaScript string literals to be treated
as tok::string_literal, not tok::char_literal, which fixes two unrelated
tests.

Patch by Martin Probst. Thank you.

2016-03-01 12:47:30 +00:00
Manuel Klimek b12e5a5ccd Add functions to apply replacements and reformat them.
This is a commonly useful feature to have, and we have implemented it
multiple times with different kinds of bugs. This implementation
centralizes the idea in a set of functions that we can then use from the various
tools.

Reverts r262234, which is a revert of r262232, and puts the functions
into FOrmat.h, as they are closely coupled to clang-format, and we
otherwise introduce a cyclic dependency between libFormat and
libTooling.
