rustfmt-unstable
Rustfmt currently allows unstable options to be passed on the commandline only when used on stable. This behaviour is known to the rustfmt team and is not intended to change until version v2.0 in which a a new feature flag will be introduced that enables these features in the config. It is often desireable to use a rustfmt.toml config anyways, even with unstable features, to enable easier sharing of configuration across machines and developers. To aid in this purpose, this crate provides a way to parse the config and pass it as arguments instead.
Usage
cargo install rustfmt-unstable
rustfmt-unstable
The rustfmt-unstable binary accepts a config file and then parses everything after the --
as the actual command to be executed with the provided config. It will then pass --config feature1=foo,feature2=bar,...
at the end of the provided command, if no --config
is found in it already. If there is, rustfmt-unstable will instead ammend the feature list with the features in the config and replace it in-place. The command defaults to cargo fmt --check --all --
.
The --apply
flag is present if you simply wish to run cargo fmt --all --
Additional config options can be either provided through the --config option on rustfmt-unstable or through the --config option on the binary you wish to execute (after the first --
).
The configuration file read can be specified by using the --config-file
option. By default (with the auto-resolve
feature enabled, which it is unless it is disabled) rustfmt-unstable tries to locate a rustfmt.toml
file at the workspace root.
Usage examples
I wish to see a diff showing all the files not formatted correctly
rustfmt-unstable
I wish to format all my unformatted files
rustfmt-unstable --apply
I wish to provide another config file and format all my files accordingly
rustfmt-unstable --config-file my-config.toml --apply
I just wish to wrap my existing cargo fmt -- --config opt_a=foo,opt_b=bar
command to use the config file correctly
rustfmt-unstable -- cargo fmt -- --config opt_a=foo,opt_b=bar
I wish to check that all my files were correctly formatted in ci
It's probably a good idea to check for overly long lines as well. I'd reccomend
rustfmt-unstable -- cargo fmt --check --all -- --config error_on_line_overflow=true
or if you don't wish to do that just
rustfmt-unstable
