Pest mode provides a major mode for editing Pest files. It also contains a few advanced features.
Current stable version: 0.1.
Pest-mode features:
- Syntax highlighting
- Indentation
- Imenu integration
- xref integration
- Eldoc integration (requires
pesta
) - Flymake/flycheck integration for syntax checking (requires
pesta
) - Language studio, where you can experiment the grammar (requires
pesta
)
pest-mode
, flymake-pest
, and flycheck-pest
are now on MELPA.
- Just
M-x package-install
bothpest-mode
andflymake-pest
. - Install
pesta
(see below).
To manually install pest-mode
, download the file and put it in your load-path
, and write in your config file:
(autoload 'pest-mode "pest-mode")
(add-to-list #'auto-mode-alist '("\\.pest\\'" . pest-mode))
If you use use-package
and quelpa
, life is easier:
(use-package pest-mode
:quelpa (pest-mode :fetcher github :repo "ksqsf/pest-mode")
:mode "\\.pest\\'"
:hook (pest-mode . flymake-mode))
To use the more advanced features, you must have pesta
installed.
pesta
is now on crates.io, so just do
cargo install pesta --force
Or, if you prefer the manual way,
- Install the Rust toolchain.
cd pesta && cargo build --release

pesta
undertarget/release

.

if pesta
is not
in your PATH
.
If you have added pest-mode
to auto-mode-alist
, then it should be enabled automatically on any .pest
file.
