The executable for the Alex linter is currently hard-coded as 'alex',
which is an issue given the fact that it conflicts with the Haskell
lexer generator, whose executable is also called 'alex', has been around
a dozen years before the linter, and is packaged in the official
repositories of the major Linux distributions.
This commit adds options to use a local executable for the alex linter
(which is a node package), and an option to set a custom executable.
As side changes:
* The pattern in the alex handler is made more readable by turnig it
into a very-magic regex.
* Alex handles plain text, markdown, and HTML. Specific flags for HTML
and markdown are provided when instantiating the linters for the
respective filetypes, while before those formats were treated as plain
text.
Similar to other linters/fixers, by default change to the directory of
the file being fixed before invoking `black`, which allows the tool to
read project-specific configuration (pyproject.toml)
Fixes#2218
* Add initial ameba (crystal linter) support
Note that this depends on saved file as `ameba` does not have STDIN
support
* Fix formatting of crystal linter documentation
* Add tests for ameba executable customization
* Extended statusline.vim to provide an efficient way to access the first errors,warnings,stylerrors,stylewarnings,etc from the loclist.
* Added documentation and help for the new API function.
Currently, we detect the linter root based on a variety of techniques.
However, these techniques are not foolproof. For example, clangd works
fine for many things without a compile_commands.json file, and Go
projects may be built outside of the GOPATH to take advantage of Go
1.11's automatic module support.
Add global and buffer-specific variables to allow the user to specify
the root, either as a string or a funcref. Make the funcrefs accept the
buffer number as an argument to make sure that they can function easily
in an asynchronous environment.
We define the global variable in the main plugin, since the LSP linter
code is not loaded unless required, and we want the variable to be able
to be read correctly by :ALEInfo regardless.
All linters should have a name variable set in their dictionary, and
code should be able to rely on that. Fix this test such that its example
linter contains a name entry.
* Mimic Prettier's default parser by setting it to `babylon`
* Add tests to check default Prettier `parser`
* Set Prettier default parser based on version
* Update the comment to explain the reason for an explicit default
* Add textDocument/typeDefinition for LSP
Doc to spec https://microsoft.github.io/language-server-protocol/specification#textDocument_typeDefinition
This works like textDocument/definition but resolves a location of a
type of an expression under the cursor.
I'm not sure what to do with tsserver though.
* Fix passing column to LSP
* test_go_to_definition: wording
* Add tests for textDocument/typeDefinition
* Add docs for textDocument/typeDefinition
ale#Escape function seems to prepend and append ' to the file name, which
are not present in the pydocstyle output. Having the parsing regexp match
the file name was overkill anyway, since there is an obvious 1:1
correspondence between the buffer number and the (potential) errors
reported by pydocstyle.
When using a compilation database (compile_commands.json) in very large
projects, significant delays would occur when changing files --
particularly those that happened to be far down the db. Rather than
iterating over the whole list every time, we now build up a lookup table
based on the tail of the filename (and tail of the directory for
widening searches) and iterate over the much smaller list of compile
commands for files with the given name.
Test metrics (from compile_database_perf/test.sh) show a 90% performance
improvement -- from 25 seconds to 2.5 seconds per run.
* Add support for https://github.com/saibing/bingo
* Add docs for ale-go-bingo
* Use go.mod when found
* Add test for bingo FindProjectRoot
* Simplify ale_linters#go#bingo#GetCommand
With earlier elm versions, a separate package file is maintained for
tests, which when properly configured enabled the compiler to find what
it needed to compile the tests. Under elm 0.19, test dependencies are
managed in the top-level package file, so `elm make` will fail on the
tests. `elm-test make` is required in this case.
See https://github.com/elm-explorations/test/issues/64
- added a cd into the direcotry containing the file in the buffer
in order to properly check for a config file
- added command_callback tests for graphql

StandardRB is to RuboCop what StandardJS is to ESLint. This commit
naively copies the RuboCop linter and fixer to point at the standardrb
executable. Any other adjustments are very minor (the only I can think
of is that standardrb takes a `--fix` option instead of
`--auto-correct`).
This raises a confusing point to me as both developer and a user: since
ale enables all linters by default, won't this run both RuboCop and
StandardRB (the results of which will almost always be in conflict with
one another)? How does ale already solve for this for the similar case
of StandardJS and ESLint?
It's common to add SwiftLint as a CocoaPod dependency, instead of as a global
binary. In this case we should use that version of SwiftLint before looking
for any others. Note that I'm also adding support for SwiftLint in ReactNative
projects here as well, where the Pods directory would be nested inside an ios
directory.
The linter can correctly parse pydocstyle output with any of the following
command-line options enabled: --explain, --source, --debug, and/or
--verbose
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.
There is currently a check that tries to prevent c-flags that contain
'-' in them from being unintentionally split and included in the list of
commands. For example, we wouldn't want "-fno-exceptions " to appear as
"-fno" and "-exceptions ". The way this check was done was by making sure
the last character of the split string was a space.
This meant that the very last option to appear in the compile command
was ignored (as it doesn't end with a space). This fix explicitly skips
the ends-with-space check on the last option in the command-line.
This isn't the best fix. Really we should be using the same
argument-processing rules as a shell would rather than just splitting on
'-'. That's a much larger and more complicated change though.
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.
Removed ale_virualtext_prefix from debugging since it's not requried for
the functionality to work.
Sorted debugging info to make the list easier to navigate/diff.
Problem: ocamlformat is configured to format files in-place and thus go
via creating a temporary file for that. Because temporary file resides
in a different directory ocamlformat can't find `.ocamlformat`
configuration files in an original location of source files.
Solution: ocamlformat since version 0.8 can read sources on stdin and
spur result on stdout. We reconfigure ocamlformat to use a simpler
interface.
Previously, elixir-ls would treat each sub-project within an umbrella as
standalone, which isn't desirable from a language server perspective.
Added ale#handlers#elixir#FindMixUmbrellaRoot, which locates the current
project's root and then continues searching upwards for a potential
umbrella project root. This literally looks just two levels up to keep
things simple while keeping in line with Elixir project conventions.
Use this new function to determine elixir-ls's LSP project root.
* Allow configuration of hamllint executable
The hamllint executable was hard-coded, preventing it from being
overridden. Fix the executable to be dynamic to allow custom executable
paths.
This adds generic configuration dictionary support to the elixir-ls
linter. This is useful for disabling its built-in Dialyzer support, for
example, which can improve startup time.
The configuration dictionary is a little verbose. I considered reducing
the user configuration to only the nested settings dictionary (and
having the linter implementation wrap it in the top-level `elixirLS`
dictionary), but leaving it fully configurable simplifies the code and
removes any assumptions about current or future ElixirLS behavior.
Each LSP connection now stores its configuration dictionary. It is
initially empty (`{}`) and is updated each time the LSP connection is
started. When a change is detected, the workspace/didChangeConfiguration
message is sent to the LSP servers with the updated configuration.
This is the callback-based variant of the existing `lsp_config` linter
option. It serves the same purpose but can be used when more complicated
processing is needed.
`lsp_config` and `lsp_config_callback` are mutually exclusive options;
if both an given, a linter preprocessing error will be raised.
The runtime logic has been wrapped in `ale#lsp_linter#GetConfig` for
convenience, similar to `ale#lsp_linter#GetOptions`.
This also adds documentation and an `AssertLSPConfig` test function for
completeness.
* add prolog/swipl linter
* use load_files/2 instead of read_term/2
Because it also checks some semantic warnings / errors
not only syntactic warnings / errors.
e.g.:
* singleton warning
* discontiguous warning
* ...
cf. http://www.swi-prolog.org/pldoc/doc_for?object=style_check/1
* support error messages with no line number
:- module(module_name, [pred/0]).
causes
ERROR: Exported procedure module_name:pred/0 is not defined
* add test for prolog/swipl handler
* cosmetic fixes
* detect timeout using SIGALRM
* rename g:prolog_swipl_goals to g:prolog_swipl_load
* write doc for prolog/swipl linter
* update toc and README
* fix ignore patterns
* Only run stack if a stack.yaml config is found
It is necessary to check for a stack.yaml file to distinguish between
cabal-only projects or stack projects (which are also cabal projects
since stack is built on top of cabal).
* Test that stack is called if stack.yaml exists
ElixirLS (https://github.com/JakeBecker/elixir-ls) is an LSP server for
Elixir. It's distributed as a release package that can be downloaded
from https://github.com/JakeBecker/elixir-ls/releases or built locally.
The easiest way to start it is via Unix- and Win32-specific helper
scripts, so that's the basis of this command integration. Alternatively,
we could implement the contents of those platform-specific scripts in
the linter's command callback in a language-neutral way, but there isn't
any benefit to doing that aside from eliminating the platform check, and
that could prove to be too tight of a coupling going forward.
* FIX: use mix from the project root directory
* Move find root project function to autoloaded handlers
* add tests for #ale#handlers#elixr#FindMixProjectRoot
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'
Oct 02, 2018 9:10:39 PM net.sourceforge.pmd.PMD processFiles
WARNING: This analysis could be faster, please consider using Incremental Analysis: https://pmd.github.io/pmd-6.7.0/pmd_userdocs_incremental_analysis.html

```
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.
These test vars were covering up a bug in the hlint linter
implementation. Without these vars we can see the behavior that is
exhibited in `vim` proper.
* 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
* Don't add newlines when not a control statement for Python
* Add test for accidental newline fix
* Add docstring detection to avoid adding unnecessarily newlines
* Add tests for docstring detection
