Not to be confused with rustfmt.
rstfmt is a tool for automatically formatting reStructuredText files in a consistent way.
Like Black and gofmt, the motivation is to provide a format that is reasonable and minimally configurable to prevent teams from wasting time on style discussions (or individuals on manually doing formatting, for that matter).
Currently, rstfmt is in an early stage of development. Not all reST constructs are covered and the interface or formatting may change at any time without warning.
To get a feel for the output of rstfmt, see the sample file.
# Install directly from the repository.
pip install git+https://github.com/dzhu/rstfmt
# Install from PyPI.
pip install rstfmt
# Read a file from stdin and write the formatted version to stdout.
rstfmt
# Don't edit any files; exit with a nonzero status code if any files are not formatted.
rstfmt --check <file>...
# Print diffs for all files that are not formatted (implies --check).
rstfmt --diff <file>...
# Format the given files in place.
rstfmt <file>...
# Format all files with the `rst` or `txt` extension inside a directory.
rstfmt <directory>...
rstfmt --ext txt <directory>...
# Wrap paragraphs to the given line length (default 72).
rstfmt -w <width>Like Black's blackd, there is also a daemon that provides formatting via HTTP requests to avoid the cost of starting and importing everything on every run.
# Install.
pip install 'git+https://github.com/dzhu/rstfmt#egg=rstfmt[d]'
pip install 'rstfmt[d]'
# Start the daemon (binds to localhost:5219 by default).
rstfmtd --bind-host=<host> --bind-port=<port>
# Print the formatted version of a file.
curl http://locahost:5219 --data-binary @<file>
# Specify the line length (default 72).
curl -H 'X-Line-Length: 72' http://locahost:5219 --data-binary @<file>
# Mimic the standalone tool: read from stdin, write to stdout, exit with
# a nonzero status code if there are errors.
curl -fsS http://locahost:5219 --data-binary @/dev/stdinThe default behavior of reading from stdin and writing to stdout should integrate well with other systems, such as on-save hooks in editors. For example, here's a configuration for reformatter.el, including both standalone and daemon modes:
;; Run the standalone tool.
(reformatter-define rstfmt
:program "rstfmt")
(add-hook 'rst-mode-hook #'rstfmt-on-save-mode)
;; Query the daemon.
(reformatter-define client-rstfmt
:program "curl"
:args '("-fsS" "http://localhost:5219" "--data-binary" "@/dev/stdin"))
(add-hook 'rst-mode-hook #'client-rstfmt-on-save-mode)
