Problem: in insert mode, `<BS>`, `<C-h>`, `<C-w>`, and `<C-u>` could
delete backwards past the name column boundary into the icon/permissions/ID
prefix, corrupting the line and breaking the parser.
Solution: add buffer-local insert-mode expr keymaps that compute the name
column boundary (cached per line) and return no-op when the cursor is
already at or before it. `<C-u>` emits exactly enough `<BS>` keys to
delete back to the boundary, never past it.
Closes#133
* refactor: revert module namespace from canola back to oil
Problem: the canola rename creates unnecessary friction for users
migrating from stevearc/oil.nvim — every `require('oil')` call and
config reference must change.
Solution: revert all module paths, URL schemes, autocmd groups,
highlight groups, and filetype names back to `oil`. The repo stays
`canola.nvim` for identity; the code is a drop-in replacement.
* refactor: remove `vim.g.oil` declarative config
Problem: the `vim.g.oil` configuration path was added prematurely.
It adds a second config entrypoint before the plugin has stabilized
enough to justify it.
Solution: remove `vim.g.oil` support from `plugin/oil.lua`,
`config.setup()`, docs, and tests. Users configure via
`require("oil").setup({})`.
Problem: the codebase still used the upstream \`oil\` naming everywhere —
URL schemes, the \`:Oil\` command, highlight groups, user events, module
paths, filetypes, buffer/window variables, LuaCATS type annotations,
vimdoc help tags, syntax groups, and internal identifiers.
Solution: mechanical rename of every reference. URL schemes now use
\`canola://\` (plus \`canola-ssh://\`, \`canola-s3://\`, \`canola-sss://\`,
\`canola-trash://\`, \`canola-test://\`). The \`:Canola\` command replaces
\`:Oil\`. All highlight groups, user events, augroups, namespaces,
filetypes, require paths, type annotations, help tags, and identifiers
follow suit. The \`upstream\` remote to \`stevearc/oil.nvim\` has been
removed and the \`vim.g.oil\` deprecation shim dropped.
* build: replace luacheck with selene
Problem: luacheck is unmaintained (last release 2018) and required
suppressing four warning classes to avoid false positives. It also
lacks first-class vim/neovim awareness.
Solution: switch to selene with std='vim' for vim-aware linting.
Replace the luacheck CI job with selene, update the Makefile lint
target, and delete .luacheckrc.
* build: add nix devshell and pre-commit hooks
Problem: oil.nvim had no reproducible dev environment. The .envrc
set up a Python venv for the now-removed docgen pipeline, and there
were no pre-commit hooks for local formatting checks.
Solution: add flake.nix with stylua, selene, and prettier in the
devshell. Replace the stale Python .envrc with 'use flake'. Add
.pre-commit-config.yaml with stylua and prettier hooks matching
other plugins in the repo collection.
* fix: format with stylua
* build(selene): configure lints and add inline suppressions
Problem: selene fails on 5 errors and 3 warnings from upstream code
patterns that are intentional (mixed tables in config API, unused
callback parameters, identical if branches for readability).
Solution: globally allow mixed_table and unused_variable (high volume,
inherent to the codebase design). Add inline selene:allow directives
for the 8 remaining issues: if_same_then_else (4), mismatched_arg_count
(1), empty_if (2), global_usage (1). Remove .envrc from tracking.
* build: switch typecheck action to mrcjkb/lua-typecheck-action
Problem: oil.nvim used stevearc/nvim-typecheck-action, which required
cloning the action repo locally for the Makefile lint target. All
other plugins in the collection use mrcjkb/lua-typecheck-action.
Solution: swap to mrcjkb/lua-typecheck-action@v0 for consistency.
Remove the nvim-typecheck-action git clone from the Makefile and
.gitignore. Drop LuaLS from the local lint target since it requires
a full language server install — CI handles it.
Problem: the ---@cast opts -nil was placed after the first opts guard
but LuaLS loses narrowing at the second tbl_deep_extend on line 928,
causing a persistent need-check-nil warning at opts.refetch.
Solution: remove the redundant first opts = opts or {} guard (the
tbl_deep_extend already handles nil) and place the cast after the
second tbl_deep_extend where opts is actually used.
Problem: LuaLS still warns at opts.refetch access because it does not
track narrowing through opts = opts or {}.
Solution: add ---@cast opts -nil after the guard, matching the same
pattern used in util.render_text.
Problem: CI typecheck fails with 13 warnings — 11 need-check-nil in
util.render_text (opts param annotated nil|table but guaranteed non-nil
after tbl_deep_extend), 1 undefined-doc-param in view.render_buffer_async
(annotation says "callback" but param is "caller_callback"), and 1
need-check-nil on opts in the same function.
Solution: add ---@cast opts -nil after the tbl_deep_extend call, fix
the param name in the doc annotation, and add opts = opts or {} guard.
Problem: when a symlink target path contains a newline character, the
rendered line passed to nvim_buf_set_lines includes that newline,
causing the error "'replacement string' item contains newlines".
Solution: apply the same gsub("\n", "") sanitization to meta.link in
get_link_text that is already used for entry names at line 791.
Resolves: stevearc/oil.nvim#673
Problem: when Neovim is started with -R (read-only), all buffers get
readonly=true. Oil's render_buffer toggles modifiable to write directory
listings, which triggers "W10: Warning: Changing a readonly file" on
every directory navigation.
Solution: clear readonly on oil buffers during initialization. Oil
buffers are buftype=acwrite — readonly has no meaning for them since
writes go through BufWriteCmd, not the filesystem.
Resolves: stevearc/oil.nvim#642
Problem: executable files were visually indistinguishable from regular
files in oil buffers.
Solution: add OilExecutable highlight group (linked to DiagnosticOk)
that detects executables via Unix permission bits (S_IXUSR|S_IXGRP|
S_IXOTH) and Windows executable extensions (.exe, .bat, .cmd, .com,
.ps1). Applied to both regular files and symlink targets.
Based on: stevearc/oil.nvim#698Closesstevearc/oil.nvim#679
Problem: the is_hidden_file and is_always_hidden config callbacks
only received (name, bufnr), making it impossible to filter by entry
type, permissions, or other metadata without reimplementing entry
lookup.
Solution: pass the full oil.Entry as a third argument to both
callbacks. Existing configs that only accept (name, bufnr) are
unaffected since Lua silently ignores extra arguments. The internal
should_display function signature changes from (name, bufnr) to
(bufnr, entry) to reflect its new contract.
Cherry-picked from: stevearc/oil.nvim#644
Problem: third-party plugins like oil-git-status.nvim had no way to
know when an oil buffer was re-rendered after a filesystem change,
causing their decorations to be cleared with no signal to refresh.
Solution: emit a User OilReadPost autocmd after every successful
render_buffer_async call. Also document all oil user events
(OilEnter, OilReadPost, OilMutationComplete) in oil.txt since none
were previously documented.

* fix: support natural ordering for numbers with >12 digits
Changes the column ordering code when `view_options.natural_order`
is enabled, so that it can support larger numbers.
The previous 12-digit padding approach breaks for numbers above 12
digits.
This length-prefixed approach can scale to much higher numbers.
I picked %03 (padding 3 digits) because most filesystems don't allow
more than 255 bytes in a path segment, and "255" is 3 digits long.
* add memoization to natural order sorting
* remove call to unpack
* pass bufnr to the constrain_cursor
* return early if the oil buffer is not the current buffer
