81821acd59 Implement lint that checks for unidiomatic unwrap() (fixes #1770) 
This checks for things like

    if x.is_some() {
        x.unwrap()
    }

which should be written using `if let` or `match` instead.

In the process I moved some logic to determine which variables are
mutated in an expression to utils/usage.rs.

5379fc1b28 better parsing of condition in while loop for mutability 
allow condition to be a block: by calling visit_expr of the visitor directly on the condition instead of walk_expr on the whole expression, we bypass the match to ExprWhile that calls visit_expr on the condition and visit_block on the body. This allow to re-enable visit_block in the visitor, as it won't be called on the while body
allow condition to use static variables: maintain a list of static variables used, and if they are mutable

Fix useless_format false positive with macros 
Clippy was issuing a warning when `format!` was used inside a macro.
That's a problem because macros have different syntax and can be outside
the control of the user.

This skips the `useless_format` check if the `format!` call is inside a
macro.

1ab96db791 Make dogfood test output to seperate directory 
This commit makes `cargo clippy` output the build artifacts to a
separate directory if the `CLIPPY_DOGFOOD` env var is set. This should
prevent dogfood builds from interfering with regular builds.

This should help with issue #2595.

Handle nested block comments 2018-03-30 12:36:50 +02:00

Fix false positive in empty_line_after_outer_attr 
Before, when you had a block comment between an attribute and the
following item like this:

```rust
\#[crate_type = "lib"]
/*

*/
pub struct Rust;
```

It would cause a false positive on the lint, because there is an empty
line inside the block comment.

This makes sure that basic block comments are detected and removed from
the snippet that was created before.

546d2fec29 Fix enum_glob_use false positives 
Closes #2397.

This checks the def of the `ItemUse` path instead of checking the
capitalization of the path segements. It was noted that this def would
sometimes be `Def::Mod` instead of `Def::Enum` but it seems correct now.

Fix false positive in empty_line_after_outer_attribute 
`empty_line_after_outer_attribute` produced a false positive warning when
deriving `Copy` and/or `Clone` for an item.

It looks like the second point in [this comment][that_comment] is related,
as the attribute that causes the false positive has a path of
`rustc_copy_clone_marker`.

Fixes #2475

8494f57c82 Fix author lint 
The author lint was generating invalid code as shown on issue:
https://github.com/rust-lang-nursery/rust-clippy/issues/2442

I've changed the generated code to properly track cast
expressions.

Unfortunatelly, I've had to rewrite the `visit_decl` method, to
avoid that last if of the chain will be added. After looking at the code,
this last line was being added because of the `let x: char` part, but not
because of the `0x45df as char` expression.

It seems that let statements should not generate code on the author
lint, but I'm not sure that this is true or if I'm breaking
something on other code generation parts.

Finally, I've added a test for the author lint, but I'm not sure that
this needs to be added to the testsuite.

Lint multiline attributes properly 
This makes it so that the `empty_line_after_outer_attribute` lint only
checks for newlines between the end of the attribute and the beginning
of the following item.

We need to check for the empty line count being bigger than 2 because
now the snippet of valid code contains only `\n` and splitting it
produces `["", ""]`
Invalid code will contain more than 2 empty strings.

Partly fix incorrect useless_attribute suggestion 
This fixes an incorrect suggestion from the `useless_attribute` lint
when using `cfg_attr`.

Additionally, it will not show a suggestion anymore, if the attribute
begins on a previous line, because it is much harder to construct the
span of multi-line `cfg_attr` attributes as they don't appear in the AST.

To fix it completely, one would have to parse upwards into the file,
and find the beginning of the `cfg_attr` attribute.

Fix false positive in empty_line_after_outer_attr 
Doc comments are syntactic sugar for #[doc] attributes, so this lint was
catching them, too.

This commit makes it so that doc comments are ignored in this lint.

I think, for normal attributes it makes sense to warn about following empty
lines, for doc comments, less. This way the user has some freedom over
the formatting.

5f3c340bfb Lint for trait methods without bodies 
As discussed in rust-lang/rust#47475 the #[inline] attribute is
currently allowed on trait methods without bodies (i.e. without a
default implementation). This is misleading as it could be interpreted
as affecting the implementations of the trait method. Add a lint for any
use of #[inline] on a trait method without a body.

Fixes rust-lang/rust#47475
