The checkstyle handler is capable of parsing the new and old output
formats. Unfortunately there are some particular output messages that
matched both the new and old regular expressions:
[WARN] whatever:11:7: WhitespaceAround: ''if'' is not followed by whitespace. [WhitespaceAround]
This caused ALE to report extra errors since the message was being
matched twice, once as a warning and another (incorrect) old formatted
error.
This MR fixes this by stopping any parsing using the old format regexp
is any errors of the new format are correcly parsed. There is no reason
to expect checkstyle to output both styles in the same report.
We were setting the -data parameter to the project root but this caused
the language server to fail initialization and synch of gradle
dependencies. As consequence ALE failed to work fully on gradle
projects.
This fix sets the workspace to the parent folder of the project root.
Normally this corresponds to the correct Eclipse workspace path.
When this is not the case, this fix also allows users to explicitly set
the absolute path to the workspace via configuration variable.
* Search eclipselsp jar and config files within system package path
* Allow setting an alternate eclipselsp configuration directory
* Add test for ale_java_eclipselsp_config_path
- Set default value to $HOME/eclipse.jdt.ls
- Make JAR search regexp more specific.
- Allow to set the VSCode extensions folder as ale_java_eclipselsp_path.
The command used to invoke the LSP process was being escaped wrong.
Also added a new option to set a different java executable and fixed the
documentation.
The output format used by older checkstyle versions differs from the one
of new versions. This commit adds a second parsing iteration on the
output lines with a suitable pattern to support both versions in
parallel. Due to the differences in the order of matching groups this is
hard to achieve in a single pass through the output lines.
An appropriate test case is added.
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.
* 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.
* Remove 'col' from linters where it is hardcoded to 1
When 'col' is 1, the first column will get highlighted for no reason. It
should be 0 (which is the default).
In the scalac linter there was also a check about the outcome of
`stridx`. It would set l:col to 0 if it was -1, and then it uses
`'col': l:col + 1` to convert the outcome of `stridx` to the actual
column number. This will make 'col' equals 1 when there is no match. We
can remove the check because `-1 + 1 = 0`.
* Remove outdated comments about vcol
vcol was added as a default, and the loclists that follow these comments
do not contain 'vcol' anymore
* A try at javac support for ALE
* Small cleanup: moved '/tmp/java_ale' string into script var
* Fixed Travis-CI build failing on autocmd not being in augroup and stupid omission
* One more fix for Travis-CI
* For some reason, expandtab was not set
* Indentation and removal of header guard.
Used examples from ale_linters/c/gcc.vim and
ale_linters/javascript/eslint.vim for the indentation of string concat blocks.
