Allows the user to override $GO111MODULE environment variable through
ale options. This gives control over the default behavior of Go module
resolution.
Golang documentation:
https://github.com/golang/go/wiki/Modules#how-to-use-modules
Add `ale#Go#EnvString()` function to make it easy to add similar Go
environment variables in the future.
Use the new `EnvString` function in all available Go tools callbacks
& update tests
Also add test of linter command callback for `gofmt`
The default for `g:ale_lint_on_insert_leave` was recently changed to 1,
so it now needs to be explicitly set to 0 to run linters only when files
are saved.
Deoplete needs `get_complete_position` method and it has a different
signature. It already fetches the input string and attempts to detect
the position with `\k*` regexp patterns.
This option is used to determine if `min_pattern_length` is ignored.
In usual, it does not start completion when the matched input string is
shorter than `min_pattern_length`. But when the string matches
`input_pattern`, it starts completion even when ths string is `''`.
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.
