All notable changes to this project will be documented in this file. The format is based on Keep a Changelog.
- shfmt uses 4 spaces instead of tabs by default.
- bean-format for Beancount (#101).
- stylua for Lua (#105).
- The arguments of formatters defined as Elisp functions has changed.
A formatter function should now be a
cl-defun
taking key-value arguments with support for more keys being provided on a later apheleia release (by including&allow-other-keys
in the parameter list). For a list of provided arguments seeapheleia--run-formatter-function
. - Emacs 25 is no longer supported.
- Ocamlformat is now used in
caml-mode
in addition totuareg-mode
(#94).
- Support remote files and buffers that were opened through TRAMP (#33).
- The interface to
apheleia-format-buffer
has changed. You now pass in the symbol of a formatter fromapheleia-formatters
(or a list of them) rather than the actual command. This change improves the ability of Apheleia to report useful error messages and logging. - Stdout and stderr buffers are no longer retained after running a
formatter. Instead, the stderr is appended into an
*apheleia-cmdname-log*
buffer if it fails, or unconditionally if the new user optionapheleia-log-only-errors
is set to nil. See #64, #65. The log buffer is not hidden by default, unlike the old stdout and stderr buffers, but this can be changed with the new user optionapheleia-hide-log-buffers
. Also, the log shows all command output rather than just the latest run. You can add further customizations using the new hookapheleia-formatter-exited-hook
(#69).
- Apheleia can now format buffers that do not have an underlying file (#52).
- You can now use a Lisp function as a formatter, by providing a
symbol or lambda in
apheleia-formatters
rather than a list of strings (#62). The function should be acl-defun
taking key-value arguments with support for more keys being provided on a later apheleia release (by including&allow-other-keys
in the parameter list). For a list of provided arguments seeapheleia--run-formatter-function
. - Formatters that operate on files in place are now supported, by
using the symbol
inplace
in an entry onapheleia-formatters
to stand in for the name of a temporary file that will be modified in place by the formatter (#23).
- The buffer-local variable
apheleia-formatter
is now marked as safe (#74). This allows you to configure the formatter that Apheleia will use in a file-local variable. Note: only formatters already declared inapheleia-formatters
can be used; this does not allow arbitrary shell commands to be specified in file-local variables.
- Allow running the same formatter in multiple buffers in parallel (#64, #65). Previously, when saving a number of files at the same time, the contents of those buffers could be corrupted by a race condition.
- In some circumstances the error
wrong-type-argument bufferp nil
could be reported when running certain formatters under Apheleia. This has been fixed. - Rustfmt is no longer passed the
--unstable-features
and--skip-children
flags, since they are not available on all versions of Rustfmt (#69). - When a formatter cannot be found, orphaned stderr processes are no longer created and left around forever (#47).
- Apheleia no longer resets the major mode to its default value when formatting a buffer. This was never intended and the bug has now been fixed (#58).
- fish_indent for Fish (#68).
- isort is passed different arguments so as not to trigger a crash
that appears to be related to the
--stdout
flag. - latexindent now has its log file disabled so as to avoid cluttering the working directory.
- ocamlformat is now configured to work even outside of detected projects.
- Support multiple formatters (#31). You can now configure a list of
formatters for a major-mode in
apheleia-mode-alist
and they will be run in sequence. - Support evaluating items in
apheleia-formatters
to make formatter commands more dynamic (#50, #55).
- ClangFormat for C/C++
google-java-format
for Java- isort for Python (#51)
- latexindent for LaTeX
- rustfmt for Rust (#24)
mix format
for Elixir (#48)@prettier/plugin-ruby
for Ruby (#49)
- Fix spelling error in generated process names (#32).
- Apheleia no longer conflicts with undo-fu (#39).
- Apheleia no longer triggers
after-set-visited-file-name-hook
, which reduces conflicts with various modes. For example,lsp-mode
will no longer trigger a reconnect every time you save. - Fix inconsistent
:type
spec preventing use ofcustomize-variable
onapheleia-formatters
. - Fix mixed style line ending generated by
diff
(#54) by adding--strip-trailing-cr
todiff
's argument list.
- Prettier is now enabled in
json-mode
.
- Prettier now respects
.prettierignore
(#21). - Apheleia's global mode should no longer trigger warnings about a locally
let-bound
after-save-hook
(#27).
- New: OCamlFormat for Ocaml (#19).
- Previously, there were some race conditions related to switching the current buffer. In particular, if you switched the current buffer right after saving, or save two buffers in quick succession, then it was possible for one buffer to be overwritten or to not be formatted. These problems have been fixed (#8).
- Previously, enabling
undo-tree-auto-save-history
caused Apheleia to mark the buffer as modified after formatting. This has been fixed (#10). - Apheleia now tries harder to accidentally enter an infinite formatting loop (#12).
- There is now a maximum length for the dynamic programming algorithm,
controlled by
apheleia-max-alignment-size
. This prevents Emacs from hanging due to Apheleia. under any circumstances (#4).
- Previously, weirdness could happen if manually running Prettier via
M-x apheleia-format-buffer
on a buffer which was modified from what was written to disk. Now we simply abort running a command that uses thefile
keyword if the buffer is modified, since it will not produce correct results. This should not affect normal usage of Apheleia. - Previously, the buffer could be erased when running Apheleia from a buffer that had no backing file. This has been fixed, and Apheleia can run correctly on buffers both with and without backing files (#9).
