How to config the formatter to just reload the file after format instead of read from the output of the formatter ?

[Dangerise]

I'm using dioXus in my rust project, and I need to use the custom formatter from dioxus because of its special macro, but the output infomation will cover my source code, instead of the code after formatting

[pascalkuthe]

The formatter needs to output to stdout otherwise it won't work. Every formatter I ever encountered has an option for that.

Reloading the file from disk unsuited since that is essentially a race condition

@pascalkuthe
I found that dioxus has provide a way to support helix

now I'm trying to cargo fmt first and then do dx fmt

but It's seems that it has a problem

[Dangerise]

my formatter config

[[language]]
name = "rust"
formatter = { command = "bash", args = ["-c", "cargo fmt && dx fmt -f -"] }

[Dangerise]

all right, solved by

[[language]]
name = "rust"
formatter = { command = "bash", args = ["-c", "rustfmt | dx fmt -f -"] }

I've added -o pipefail to return if rustfmt failed, otherwise rustfmt push an empty string through stdout and so dx fmt which basically empty the buffer.

[[language]]
name = "rust"
formatter = { command = "bash", args = ["-o", "pipefail", "-c", "rustfmt | dx fmt -f -"] }

[j03-dev]

[[language]]
name = "rust"
auto-format = true
formatter = { command = "bash", args = ["-c", "rustfmt | dx fmt -f -"] }

This is my config and, when I format the code, it's delete everything all my code.

[[language]]
name = "rust"
auto-format = true
formatter = { command = "bash", args = ["-c", "rustfmt | dx fmt -f -"] }

This is my config and, when I format the code, it's delete everything all my code.

maybe something have been changed over the year, if your code has any syntax errors that lead to parse failure , the buffer will be clear .

@Marsevil has given the solution

[rrrrigel]

[[language]]
name = "rust"
auto-format = true
formatter = { command = "bash", args = ["-c", "rustfmt | dx fmt -f -"] }

This is my config and, when I format the code, it's delete everything all my code.

same here

[j03-dev]

[[language]]
name = "rust"
auto-format = true
formatter = { command = "dx", args = ["fmt", "-f", "-"] }

So I use this; it works for me, but Steel can't use it with rustfmt.
