Setting YARGS_MIN_NODE_VERSION=0.1.2 solves the issue, but then I see:

error: Could not resolve: "readline". Maybe you need to "bun install"?

const readline = require('readline');

Without a trailing newline.

Also a little question: is it possible to pass command line arguments to script I run with bun?

bun bin/putout.mjs -f dump

-f dump is handled by bun, but I need it to use other formatter that don't uses readline :).

1. The readline issue is documented in readline not available #311
2. You can pass CLI arguments by writing bun bin/putout.mjs -- -f dump

The version issue was also resolved by #392. Please close this issue.

Thanks for a quick response!

The version issue was also resolved by #392. Please close this issue.

this only modifies the napi function, and not process.version. broken on bun 0.1.3 still.

[FinnRG]

@davecaruso You're right, I'm sorry about that. Since we probably don't want to change our current process.version output, we could expose a flag like --set-version which replaces every occurrence of process.version with the set version (similar to how we replace env variable).

I dislike this because it now requires anyone using yargs or depending on a package that uses it, all devs and users need that flag. It feels the same as YARGS_MIN_NODE_VERSION, and env variable you have to specify everywhere. that would still be better than nothing, but a lot of people will try this (and any other package that may do this type of check) and complain it doesn't work.

but i do think process.version should contain the bun one since it's bun that we're running and not node. maybe they can convince yargs to switch to reading process.versions.node, but i kind of feel like they won't implement that change.

[FinnRG]

@davecaruso We should definitely try to get this into yargs. As a temporary workaround, you can use this flag: --define process.version:"\"13.0.0\"", which replaces every occurrence of process.version with the specified version.

[coderaiser]

I think the best possible process.version would be Nodejs LTS that Bun going to be compatible with and for Bun version it can be process.bunVersion or something like this.

[FinnRG]

Good news: The yargs-parser team seems to be open about adding feature detection for bun: yargs/yargs-parser#447 (comment)

[paperdave]

and better news, i just opened PR yargs/yargs-parser#450 which should fix it. this obviously wont fix any other libraries doing this, but they should all change to this way of checking node.

If someone really needs to edit process.version, you'll need two files at best. One will do:

// @ts-expect-error
process.version = 300;

await import("./other-file");

And the other one then imports the modules like yargs, etc. define flag is better

[paperdave]

btw, the process version check has been fixed, but i believe theres some other stuff we need before yargs fully works on bun; however those steps are our responsibility here and not theirs.

process.version is supported as of 0.2.2. For other compatibility issues, please file another issue and we'll track it down.
