Error during formatDockerfileContents

[NancyKunath]

Formatting a dockerfile like this

console.log(
  await formatDockerfileContents(`
FROM nginx
WORKDIR /app
ARG PROJECT_DIR=/
ARG NGINX_CONF=nginx.conf
COPY $NGINX_CONF /etc/nginx/conf.d/nginx.conf
COPY $PROJECT_DIR /app
CMD mkdir --parents /var/log/nginx && nginx -g "daemon off;"
`.trim(),
    {
      indent: 4,
      spaceRedirects: false,
      trailingNewline: true,
    },
  ),
);

Leads to the following error:

In the end, this results in prettier-plugin-sh failing because of our Dockerfile.

If you add a newline (don't trim), does it work?

Actually, this looks like an issue in the TinyGo. tinygo-org/tinygo#4376

@JounQin If you want to take a crack at fixing this, that would be great!

How could I if it's a tinygo's issue?

tinygo-org/tinygo#4277

Maybe easyjson should be used. 🤦‍♂️

[reteps]

😄 Let's give it a few weeks on tinygo's end and see if there is any progress. If not, I'll see if I can switch to easyjson.

[JounQin]

I may add a try catch for dockerfmt parser and fallback to sh automatically in the prettier plugin, if anyone is interested to raise a PR for it, that would be appreciated. I'm a bit busy these days.

Done at un-ts/prettier#455

Hi @retepsa, tinygo-org/tinygo#4277 seems won't be resolved in near future?

[reteps]

Hi @JounQin -- I won't have time for a few weeks to implement that switch, so unfortunately you will have to sit tight 😦 . Maybe some disclaimer about this on the README would prove useful until that is done?
