33.0 (2024-02-04)¶
Note
The changelog for this release is incomplete.
New features and improvements
The
flycheck-verify-setup
UI now includes buttons to re-enable manually disabled checkers and to try to re-enable automatically disabled checkers (command checkers are automatically disabled when their executable cannot be found). [GH-1755]Error explainers can now return URLs (to show a webpage) or functions (to use custom formatting). For example, the Rust checker now renders explanations using
markdown-view-mode
. [GH-1753]Enable checkers in many newer TreeSitter-based major modes (think
*-ts-mode
).
New syntax checkers
Python with
ruff
. [GH-2033]
Breaking changes
Drop support for Emacs 25.
The variable
flycheck-current-errors
now contains errors in the order in which they were returned by checkers. In previous versions of Flycheck, this list was sorted by error position and severity. [GH-1749]
32 (frozen on May 3rd, 2020, released Mar 28, 2022)¶
Highlights
Many checkers and compiler, such as
ocaml
,rust
,eslint
, and others, include end-line and end-column information. Flycheck can now highlight the exact region that they report. Authors of checker definitions can use the new:end-line
and:end-column
arguments inflycheck-error-new
, or the newend-line
andend-column
fields in error patterns. [GH-1400]Errors that checkers return for other files will now be displayed on the first line of the current buffer instead of begin discarded. The error list indicates which file each error came from, and navigation moves automatically moves between files. This change helps with compiled languages, where an error in another file may cause the current file to be considered invalid. Variables
flycheck-relevant-error-other-file-show
andflycheck-relevant-error-other-file-minimum-level
control this behavior. [GH-1427]Flycheck can now draw error indicators in margins in addition to fringes. Margins can contain arbitrary characters and images, not just monochrome bitmaps, allowing for a better experience on high-DPI screens.
flycheck-indication-mode
controls this behavior, andflycheck-set-indication-mode
can be used to automatically adjust the fringes and margins. Additionally, Flycheck’s will now use high-resolution fringe bitmaps if the fringe is wide enough [GH-1742, GH-1744]Error highlighting is now configurable, using the new
flycheck-highlighting-style
variable: instead of applying level-dependent faces (typically with wavy underlines), Flycheck can now insert delimiters around errors, or mix styles depending on how many lines an error covers. Additionally, stipples are added in the fringes to indicate errors that span multiple lines. [GH-1743]
New features and improvements
Flycheck can now trigger a syntax check automatically after switching buffers, using the
idle-buffer-switch
option inflycheck-check-syntax-automatically
. This is useful when errors in a file are due to problems in a separate file. Variablesflycheck-idle-buffer-switch-delay
andflycheck-buffer-switch-check-intermediate-buffers
control the functionality. [GH-1297]Flycheck will now use Emacs’ native XML parsing when libXML fails. This behavior can be changed by customizing
flycheck-xml-parser
. [GH-1349]flycheck-verify-setup
now shows more clearly which checkers will run in the buffer, and which are misconfigured. [GH-1478]Flycheck now locates checker executables using a customizable function,
flycheck-executable-find
. The default value of this function allows relative paths (set e.g. in file or dir-local variables) in addition to absolute paths and executable names. [GH-1485]Checkers that report error positions as a single offset from the start of the file can use the new
flycheck-error-new-at-pos
constructor instead of converting that position to a line and a column. [GH-1400]Config-file variables can now be set to a list of file names. This is useful for checkers like mypy which don’t run correctly when called from a subdirectory without passing an explicit config file. [GH-1711]
Thanks to algorithmic improvements in error reporting, Flycheck is now much faster in large buffers. [GH-1750]

26 (Apr 27, 2016)¶
Flycheck now has a Code of Conduct which defines the acceptable behaviour and the moderation guidelines for the Flycheck community. [GH-819]
Flycheck also provides a Gitter channel now for questions and discussions about development. [GH-820]
The native Texinfo manual is again replaced with a Sphinx based documentation. We hope that this change makes the manual easier to edit and to maintain and more welcoming for new contributors. The downside is that we can not longer include a Info manual in Flycheck’s MELPA packages.
From this release onward Flycheck will use a single continuously increasing version number. Breaking changes may occur at any point.
