This MR adds a new configuration variable `g:ale_java_javalsp_config`
that allows to configure external dependencies and class paths to the
language server.
The variable accepts a dictionary similar to the one supported by the
[vscode/settings.json](https://github.com/georgewfraser/java-language-server#settings)
file.
Deprecates: #2561
Checkstyle xml configuration is mandatory and not providing one causes
the tool to fail with the following error:
Must specify a config XML file.
Checkstyle itself contains a default configuration as part of its
assests named `/google_checks.xml`. Invoking checkstyle with this config
works even if such file does not exists in the file system:
checkstyle -c /google_checks.xml
This should be the default invocation to allow ALE to use checkstyle
with zero configuration.
Also when a user sets `g:ale_java_checkstyle_config` option, ALE should
use it to invoke checkstyle even such file does not exists in the
filesystem. This is because checkstyle is able to use configuration files
within JAR files defined in the CLASSPATH. The default `/google_checks.xml`
is an example of such configuration available within a JAR resource.
The default binary "launcher" is too generic and can get mixed with
other tools. To use this linter user must explicitly set the absolute
path of the launcher path.
isort is great, but I've come to prefer reorder-python-imports. The tool
has a focus on smaller diffs than isort. reorder-python-imports is also
a little smarter than isort which is nice.
The existing option setting handles setting additional compile flags to
pass to clang-tidy. The new option setting added here allows setting
additional clang-tidy specific flags to be passed as well.
Fixes#2324
The command used to invoke the language server is missing some options
to include additional java modules. Without these modules the server
was not working properly.
The correct command can be found in a `launcher` script on the same
directory the `java` executable for the language server is found.
This commit changes the docs to prefer the launcher script over the java
executable. For backward compatibility it also fixes the command
invocation in case the java executable is configured.
cppcheck is now run without the --project option and from the buffer's
directory instead when the buffer has been modified. Saving the buffer
will get results by linting the project instead.
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.
