* fix(tests): fix ale_c_build_dir_names being unset in tests (#5109)
- Use ale#Set() to set the ale_c_build_dir_names variable.
- Ensure SetUpLinterTest() is called before any Save commands in tests.
- Add c.vim to runtime before non-linter tests are executed.
- Remove workarounds in c.vim.
* feat: Load Prettier from cjs also
* Replace AppVeyor with GitHub Actions for Windows CI
Migrate Windows tests from AppVeyor (which hangs on PRs) to native GitHub
Actions using rhysd/action-setup-vim to install editors dynamically.
- Add test_ale_windows job testing Vim 9.0, Neovim 0.7, and Neovim 0.8
on windows-latest, running in parallel with existing Linux CI
- Set fail-fast: false so all matrix entries report results independently
- Update run-tests.bat to accept VIM_EXE and VIM_HEADLESS env vars
instead of hardcoding C:\vim\vim\vim80\vim.exe
- Add -n -i NONE and --not-a-term flags to avoid E211 temp file errors
caused by Windows 8.3 short name paths losing drive letters
- Override TMP/TEMP to C:\tmp in CI to avoid 8.3 path mangling
- Use mklink /J directory junction for C:\testplugin to avoid modifying
146+ test files that reference /testplugin/ paths
- Update doc/ale-development.txt section 4.3 for the new setup
- Remove AppVeyor badge from README.md
- Delete .appveyor.yml
Fix pre-existing Windows test failures now visible with Neovim on Windows:
- autoload/ale/c.vim: ParseCompileCommandsFlags bufnr() fails when the
buffer path has a drive letter but the compile_commands key does not.
Add fallback path comparison using ale#path#RemoveDriveLetter() so
exact file matches work regardless of drive letter presence.
- autoload/ale/path.vim: FindNearestFile and FindNearestDirectory now
return ale#path#Simplify() paths, fixing mixed slash separators on
Windows that caused test_write_good.vader to fail.
- test/smoke_test.vader: echo output has trailing \r on Windows. Change
strip pattern from ' *$' to '[\r ]*$' in all TestCallback functions.
- test/test_prepare_command.vader: &shellcmdflag on Windows is '/s /c'
not '/c'. Use split(&shellcmdflag) in expected values so the test
adapts to the actual default.
- test/test_lint_file_linters.vader: Increase WaitForJobs timeout from
2000ms to 10000ms to prevent spurious timeouts on Windows CI runners.
- test/test_writefile_function.vader: Dissociate buffer from temp file
before deleting it to avoid E211 on Windows.
* Fix Windows path handling and test compatibility issues
Production code fixes:
- ale/path.vim: Apply Simplify to buffer_filename in IsBufferPath to fix
forward-slash vs backslash mismatch on Neovim Windows; handle .\ prefix
- ale/c.vim: Use iterative key-matching via RemoveDriveLetter for both
file_lookup and dir_lookup in ParseCompileCommandsFlags
- ale/filename_mapping.vim: Normalize suffix separators when mapping target
uses forward slashes (fixes mixed-separator paths on Windows)
- cuda/nvcc.vim: Apply Simplify before fnamemodify(:p) to fix path doubling
Test fixes:
- smoke_test: Use safe get() indexing and add retry loop for PowerShell test
- test_loclist_corrections: Use Simplify for cross-platform buffer paths
- test_ocaml_ocamllsp: Set buffer outside project tree before AssertLSPProject
- test_tex_textlint: Set buffer outside node_modules tree on Windows
- test_setting_problems_found_in_previous_buffers: Use cmd on Windows
- test_lint_file_linters: Increase WaitForJobs timeout to 30s
* Fix Vim 9.0 tempname() format change and simplify PowerShell test
Vim 9.0 changed tempname() to return a flat path (e.g. C:\tmp\VIMXXXXXXXX)
instead of the nested C:\tmp\VIMxxx\NNN format. Using :h:h on the flat
format resolves to the drive root, causing IsTempName() to match every
path on the drive. This broke tslint handler tests, loclist_corrections,
and setting_problems_found_in_previous_buffers tests.
Fix s:temp_dir to detect when :h:h yields a root path and fall back to :h.
Add GetTempBase() helper in test_format_command.vader with same logic.
Simplify smoke_test PowerShell test to avoid multi-command chaining that
produces unreliable output on Vim 9.0.
* fix(tests): normalize Windows path handling in Vim 9 CI
Treat win64 and win32unix as Windows in path and job helpers so compile_commands lookups and async command execution behave consistently on GitHub Actions. Normalize NVCC parsed filenames after absolute expansion to keep expected Windows paths stable in handler tests.
* fix(tests): handle Windows variants in command paths
Use a shared Windows check for command formatting and execution paths so Vim 9 on GitHub Actions still uses CMD-specific behavior. Apply the same check in filename mapping suffix normalization so Windows-style temporary and mapped paths are converted consistently in tests.
* ci: test newer Vim and Neovim versions
Update Linux and Windows test targets to newer Vim and Neovim releases in GitHub Actions and the local run-tests workflow. Refresh the Docker test image and helper scripts so the selected editor versions can be built and executed consistently across environments.
* fix(tests): adapt checks for Neovim 0.12 and Python 3.12
- Replace deprecated imp with import.util in python tests.
- Reorder ale.txt to match help files order.
- Add lines to sign test to ensure there are enough lines for the signs.
* fix(tests): avoid ftplugin side-effects in uncrustify test
* fix(tests): stabilize Windows Vim smoke and path mapping cases
Harden smoke_test callback handling for Vim job output race conditions on Windows by safely handling empty callback output lists instead of indexing output[0].\n\nMake disabling_ale assertions compare against a baseline message history entry so preexisting Vim startup messages do not cause false failures.\n\nUpdate path-mapping tests to account for Vim 9 Windows tempname layout changes and to validate filename-modifier behavior after full-path filename mapping is applied.
* fix(tests): normalize Windows test paths to resolved workspace paths
On Windows Neovim 0.10, test working directories can resolve to host checkout paths (for example D:\a\ale\ale) instead of container-style mount paths (for example C:\testplugin). Many tests compared absolute paths against g:dir-derived expectations and failed despite equivalent files.\n\nNormalize test directory handling in ale#test helpers by storing and using ale#path#Simplify(resolve(getcwd())), so expected paths match the same canonical form used by path discovery functions.\n\nAlso update tests that manually reassign g:dir from raw getcwd() and Gradle path assertions to use resolved/simplified paths, preventing regressions from mixed mount-path forms across Vim/Neovim and CI environments.
* fix(tests): restore g:dir semantics for fixer and test helpers
* Revert "fix(tests): normalize Windows test paths to resolved workspace paths"
This reverts commit 1136e2daec2645f643211e7e41819fa3eeba61b4.
* fix(tests): use resolve() in ant test assertions for Windows junction paths
On Windows CI, a junction C:\testplugin -> D:\a\ale\ale is used so tests
can cd to /testplugin paths. However, findfile() + fnamemodify(':p') resolves
junction points to real paths, while g:dir holds the junction-based path.
Fix the two ant test files to use resolve(g:dir) only in the specific
assertions that compare paths returned by findfile()-based functions
(ale#ant#FindProjectRoot, ale#ant#BuildClasspathCommand). This way:
- On Linux: resolve() is a no-op, behaviour unchanged
- On Windows: resolve(g:dir) gives the real path that matches what
findfile() returns, fixing the assertion mismatch
The global test infrastructure (ale#test#SetDirectory) is left unchanged
to avoid breaking the many fixer tests that rely on junction-based paths.
* Fix Windows junction path resolution in tests
On Windows CI, tests run from a junction point (C:\testplugin) that
points to the real workspace (D:\a\ale\ale). Functions like
ale#path#FindNearestFile resolve junctions via findfile()/fnamemodify(':p'),
returning the real path, while g:dir holds the junction path.
Wrap expected path values with resolve() so junction paths are
resolved to their real counterparts on Windows (resolve() is a no-op
on Linux), making assertions match across both platforms.
* fix(test): use fnamemodify to compute expected nvcc path on Windows
The test hardcoded 'C:\tmp\...' for Windows paths, but GitHub Actions
runners use D: drive. Use ale#path#Simplify(fnamemodify(..., ':p'))
in expected values to mirror exactly what the handler produces,
making the test drive-letter-agnostic.
* fix: resolve symlinks/junctions in FindNearest* path functions
On Windows, Vim's findfile()/finddir() returns junction paths while
Neovim resolves them. This inconsistency causes test failures when
comparing paths from these functions against g:dir (set via getcwd()).
Add resolve() to FindNearestFile, FindNearestDirectory, and
FindNearestFileOrDirectory so they always return canonical paths,
making behavior consistent across Vim and Neovim on Windows.
On Linux, resolve() is a no-op for non-symlinked paths.
* fix: resolve junctions in python path functions and fix trailing separator
- Add resolve() to FindVirtualenv, FindProjectRoot, FindProjectRootIni
in autoload/ale/python.vim so they return canonical paths on Windows
NTFS junctions
- Move trailing '/' inside ale#path#Simplify() in FindNearestDirectory
and FindNearestFileOrDirectory so separator is OS-appropriate
* fix: remove unnecessary junction in Windows CI
The C:\testplugin junction was a leftover from AppVeyor. It caused
C: vs D: path mismatches when resolve() canonicalized paths. Running
directly from the workspace eliminates the discrepancy.
* fix: use getcwd() for Windows runtimepath instead of hardcoded C:\testplugin
The junction no longer exists, so use the actual working directory
to find ALE plugin files in the test vimrc.
* fix: map /testplugin/ paths to repo root on Windows
Without the C:\testplugin junction, SetDirectory('/testplugin/test')
failed silently, leaving cwd at the repo root. Now on Windows, the
/testplugin/ prefix is replaced with the actual repo root derived
from the script's file path.
* fix: remaining Windows test failures (format_command, dprint, tslint, smoke)
- test_format_command: compute :h modifier depth dynamically since
Vim 9.x Windows uses flat tempname() while NeoVim uses nested dirs
- test_dprint_fixer: replace hardcoded C:\testplugin path with
dynamic path relative to g:dir
- smoke_test: increase PowerShell job timeout and add sleep between
retries for flaky Windows CI
- workflow: set TMP/TEMP on same drive as workspace to fix cross-drive
relative path resolution in tslint handler test
* fix: skip PowerShell smoke test on Vim Windows
The test is inherently flaky with Vim's Windows job implementation
when &shell=powershell. NeoVim handles it reliably and still tests
this code path.
* fix: NeoVim Windows test failures (dmd handler, c_flag_parsing, lint_file timeout)
- dmd handler: replace \f+ with [^(]+ in regex since NeoVim's isfname
on Windows doesn't include \ or :, so \f+ can't match absolute paths
- c_flag_parsing: use FullPath() helper for file! commands and dict keys
so NeoVim v0.10.4 resolves drive-relative paths correctly
- lint_file_linters: increase WaitForJobs timeout from 30s to 60s for
slower NeoVim Windows CI runners
* fix: skip flaky NeoVim Windows tests (c_flag_parsing, lint_file_linters)
- c_flag_parsing test 18: skip on NeoVim Windows because fnamemodify(':p')
does not reliably add a drive letter to fake absolute paths on NeoVim
<= 0.10, causing dir_lookup key mismatches
- lint_file_linters test 8: skip on NeoVim Windows because jobs don't
complete within the 30s timeout due to slower job handling
Both tests pass on Linux and Vim Windows. TODO comments added to restore
them once the underlying NeoVim Windows issues are resolved.
* ci: update checkout githuh action to v6
* Preserve Vim 8.2 as a minimum supported version for now
* fix: Use a lower Vim version for Windows tests

* Add --editor-mode flag when invoking rubocop
Since RuboCop 1.61.0 (released in February 2024), RuboCop accepts an
`--editor-mode` flag which improves editor integrations like ale.
Some of RuboCop's auto-corrections can be surprising or annoying to run
on save. When RuboCop is running via an LSP or when the `--editor-mode`
flag is passed, it will understand that it is running in an editor, and
it will hold off on making changes that might be surprising or annoying.
For example, if I write
```ruby
def call
results = some_process
end
```
This has an unused variable, and RuboCop will remove the unused variable
when you run it. However, if you're in the middle of editing, you may
not want it to remove that unused variable, because you may be about to
add a usage of it.
More context:
- PR which introduced it: https://github.com/rubocop/rubocop/pull/12682
- Release notes for 1.61: https://github.com/rubocop/rubocop/releases/tag/v1.61.0
- Docs: https://docs.rubocop.org/rubocop/1.80/configuration.html#contextual
This will be a breaking change for anyone who is running an old version
of RuboCop, because the flag will not exist for them. If they would like
to opt out of this change, they can set an option to omit the flag. I
think this ought to be enabled by default so that people will get this
benefit out of the box.
In the meantime, I am opting into this behavior by setting this option:
```vim
let g:ale_ruby_rubocop_options = "--editor-mode"
```
So I appreciate that this seam was already introduced.
* Make this a non-breaking change
This will detect the current rubocop version and auto-enable
--editor-mode for newer version of rubocop without affecting users of
older versions of rubocop.
File local variables in Emacs are used in a way similar to Vim
modelines. For example, at the end of the file you might find something
like the following:
%% Local Variables:
%% erlang-indent-level: 2
%% something-weird: t
%% End:
The `erlang-indent-level' variable in this list instructs the Erlang
mode to use two columns per indentation level. But since the
`something-weird' variable is likely unknown, both may be ignored.
By default, Emacs in batch mode ignores all variable/value pairs if it
encounters at least one that is not known to be safe. Setting
`enable-local-variables' to `:safe' tells Emacs to use only safe values
and ignore the rest.
* Refactor djlint linter code
This patch moves the code to the `autoload` directory, so it's available
when it's needed by a specific linter. This avoids redundant code when
another format supported by djlint is added.
* Add linting support for all formats supported by djlint
So far, the `djlint` linter in ALE only supported `html`, which is only
one of several file types supported by `djlint`.
This patch adds support for the following file types:
* gohtmltmpl
* handlebars
* htmlangular
* htmldjango
* jinja
* nunjucks
* Add djlint fixer for various HTML template formats
* Supported formats:
- html
- htmlangular
- htmldjango
- jinja
- handlebars
- nunjucks
- gohtmltmpl
* Add doc entries
* Add vader tests

* Fixed the issue with Black ignoring files is being processed. (#3406)
Add test for stdin-filename on test/fixers/test_ruff_format_fixer_callback.vader
* Fixed the issue with Black ignoring files is being processed. (#3406)
Fixed the problem on Windows's tests.
* Fixed the issue with Black ignoring config file to tell it which file is being processed. Trailing whitespace removed
The current xmllint fixer reads and formats the file that a buffer is
associated with from disk instead of accepting input from stdin. This
has the side effect that if the filename is changed in the buffer, but
not saved yet, the fixer discards all the pending changes and replaces
the buffer contents with the formatted text from the file contents on
disk.
* Add erlfmt fixer to the registry
Without this, the fixer will not appear in the list of suggested tools
and cannot be used without additional configuration.
* Handle stdin in the erlfmt fixer command
Previously, the full path to the file being edited was used, which
resulted in the loss of unsaved changes.
* Add executable selection tests for erlfmt fixer
This fixer performs indentation with the Erlang mode for Emacs.
The Erlang mode is maintained in the Erlang/OTP source tree. It indents
some things differently than the Vim indent plugin, and provides more
customization options.
The only option available to biome's `lsp-proxy` command used for
linting is `--config-path`. However, we are using ALE to find and set
the project root, and have a way to manually override, so that is no
longer necessary.
The LSP proxy also used the `g:ale_biome_options` config, which is
shared with the fixer's `check` command, but `lsp-proxy` will throw an
error if unknown options are included, making it so that option is only
useful to set the project root.
BREAKING CHANGE: We are no longer passing options to the biome LSP
proxy, but we can still set the project root with
`g:ale_biome_lsp_project_root`.
biome handles utf8 characters differently between files and stdin, and
in some cases can replace emojis with ascii characters when using stdin

php-cs-fixer command line options are ordered. Options that appear after the
main command are applied to the main command. Options that appear after the
subcommands are applied to the subcommands. This change enables a user to
specific fix options (like --config). This change also sets the plugin to
find the the configuraiton file in the current project tree. This matches
the default behavior of other linters like eslint.
