PMD is currently not working properly for Java classes that use [unnamed
packages](https://docs.oracle.com/javase/specs/jls/se11/html/jls-7.html#jls-7.4.2).
Consider the following Java class that does not contain a `package`
declaration:
```java
public class App {
String getGreeting() {
return "Hello world.";
}
static void main(String... args) {
System.out.println(new App().getGreeting());
}
}
```
Running PMD in the command line agaist the Java class above produces an
output with empty string `""` in the `"Package"` column:
```sh
$ pmd -R category/java/bestpractices.xml -f csv -d './src/main/java/App.java'

```
But the pmd.vim handler's current pattern refuses everything coming
from a Java class that does not have a package name (2nd column):
```vim
let l:pattern = '"\(\d\+\)",".\+","\(.\+\)","\(\d\+\)","\(\d\+\)","\(.\+\)","\(.\+\)","\(.\+\)"$'
```
The solution I am proposing is to also accept empty strings as package names.
* Add better support for Haskell stack compiler tools
This commit adds support for `stack` as the executable of a tool. This
follows a pattern that has been implemented for `bundler`'s tool chain.
* Move hlint command to linter file
* Add vader test for stack exec handling
* Update ghc-mod to support stack execution
`ghc-mod` was previously broken into 2 linters.
1. ghc_mod
2. stack_ghc_mod
This additional linter is not necessary with proper support for
executable variables and `stack exec` handling.
* Support stack exec in hfmt
* Support stack in hdevtools
In a lint context, it's useful to assume that included files sit next to
the current file by default. Users can still further customize this
configuration variable to add more include paths.
When set to true, and the buffer is currently inside a pipenv,
GetExecutable will return "pipenv", which will trigger the existing
functionality to append the correct pipenv arguments to run each linter.
Defaults to false.
I was going to implement ale#python#PipenvPresent by invoking
`pipenv --venv` or `pipenv --where`, but it seemed to be abominably
slow, even to the point where the test suite wasn't even finishing
("Tried to run tests 3 times"). The diff is:

Using vim's `findfile` is much faster, behaves correctly in the majority
of situations, and also works reliably when the `pipenv` command doesn't
exist.
* The project style linter now runs while you type.
* Now the scripts for checking the project require blank lines.
* Many style issues have been found and fixed.
It can be necessary to pass options to the puppet parser validation. The
most glaring example of this is when using Puppet 3, with the
`parser = future` option enabled. This update allows adding
`--parser=future` to the options passed to Puppet.
I see no reason to do this? It is just setting the environment to what
it already is?
It was originally added in #297, but that entire PR is not a great idea
in the first place; that PR (together with #270) tried to make the Go do
non-standard and non-supported stuff like compiling packages outside of
GOPATH.
That's not something that works well (I tried), so was eventually
removed in #465, but these "go env" calls remained, for no reason in
particular, as far as I can think of.
This will improve on #1834; you will now no longer get a confusing error
(but still won't get a meaningful error; need to think how to do that).
* Adding support for haskell-ide-engine
* Work with the current directory if no stack.yaml file is found
* Added Cabal file detection, updated documentation and added tests
* Updated help
fixes#1738
- Replace previous `hh_client` usage with LSP client
- Add `HHAST` linter
- Split Hack from PHP: Hack is increasingly diverging from PHP:
- Hack tools do not understand PHP
- Most PHP tools do not handle Hack code well (including vim's syntax
highightling files)
- http://github.com/hhvm/vim-hack now sets filetype to `hack`
When dializer isn't a dependency, mix dialyzer recompiles the whole
project because it's not possible to know if this command dialyzer exist
or not until recompilation is done. Then the timestamps of the project
is messed up which results in broken hot-loading. In this case, mix help
dialyzer would return zero which prevents compilation of the whole
project since dialyzer isn't installed, it's help manual doesn't exist.
When dialyzer is a dependency, mix dialyzer would just run the command.
In this case, mix help dialyzer would return 1 which allows mix dialyzer
to run.
* Add kotlin languageserver linter definition
* Added kotlin languageserver references in docs, fix missing !! on other linters
* Added Vader tests for root path detection in Kotlin Language Server
* Rust Cargo linter: Improve workspace support
When using Cargo workspaces [1], there is a 'Cargo.toml' directory in a
top level directory, listing all the crates in the project. If we are
currently editing one of the crates, 'cargo build' should execute in
that directory for that crate's separate `Cargo.toml`, otherwise Cargo
may spend more time possibly rebuilding the entire workspace, and maybe
failing on one of the other crates, instead of succeeding on the current.
[1] https://doc.rust-lang.org/book/second-edition/ch14-03-cargo-workspaces.html
Like many other linters, use variables for the executable and options
used by the linter.
By default, the linter now report every warnings as errors with
`--warning-errors`.
Also add include directory and set working directory to file directory.
