[discussion] Do not use glob for prettier by default

[axetroy]

Use glob if there should be a wildcard, otherwise, use a normal file path

Otherwise, it is difficult for Prettier to format a specific file.

eg. in deno_std directory.

We want to format the test.ts file.

only this file, no one else.

deno run prettier/main.ts test.ts

Does it look right?

No.

It will format all files under deno_std directory which match with /test\.ts/g.

It is difficult to specify a file to format.

Solution

This is the solution I think:

1. Use glob when wildcards appear, Otherwise use path.

2. Don't walk the entire directory

deno_std/prettier/main.ts

Lines 245 to 253 in 47134db

	args.length > 0
	? args.map((a: string): RegExp => glob(a, options))
	: undefined;
	const files = walk(".", { match, skip });
	try {
	if (check) {
	await checkSourceFiles(files, prettierOpts);
	} else {
	await formatSourceFiles(files, prettierOpts);

BREAKING CHANGES

1. without wildcards, It will select the specified file instead of a matching file.

Before

> deno run prettier/main.ts test.ts

Formatting test.ts
Formatting fs/test.ts
Formatting fs/copy_test.ts
Formatting fs/empty_test.ts
...

After

> deno run prettier/main.ts test.ts
Formatting test.ts

In order to keep the original function unchanged, you should write like this

> deno run prettier/main.ts **/*test.ts
Formatting test.ts
Formatting fs/test.ts
Formatting fs/copy_test.ts
Formatting fs/empty_test.ts
...

Please share your thoughts and suggestions

npm has is-glob module. This looks a more robust approach to me.

source, test

[axetroy]

@kt3k yes. that's great.

Are you interested in porting it?

@axetroy
I'm interested in it, but I can't start it right now. If you can do it, I appreciate your help!

[dshubhadeep]

@axetroy I would like to work on it, if that's okay with you

[axetroy]

@dshubhadeep
I appreciate your help.

expose a new function name isGlob

export function isGlob (str: string): boolean {
 // do the staff
}

[dshubhadeep]

@axetroy in which module should I add the function ? Btw the is-glob module also checks for extglob. Should that be added as well ?

[axetroy]

@dshubhadeep
It should be added to fs module glob.ts file
