* Parse CFLAGS that can be passed using a whitelist
I went through GCC's man page and selected flags that can safely be
passed to GCC and that can be useful to syntax checking. These include:
- -I/-i* include flags
- preprocessor flags such as -D
- -W* warning flags
- -O* optimization flags
- most -f options
- -m arch dependent options
* Fix CFLAGS tests: -Idir is now parsed to -I dir
* Added two tests for flags we want or don't want to pass.
* Also check for / in addition to s:sep
* added omitted global variables which was breaking this test when run standalone
* invert logic for s:GetLinterVariables excluding disabled linters, so that linter global options can appear in output
* additional tests for s:GetLinterVariables for linter global options
On some systems, notably NixOS, there is no `/bin/ls` and thus this test
can fail unnecessarily on those systems. This commit uses
`/usr/bin/env ls` which resolves the issue.
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`
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
