Hi folks 🎈!

The time is come for a new big release! It has much less breaking changes then previous one.

Anyways some significant things been changes...

Alternative to recast: @putout/printer

This spring I understand that I’m tired of poor maintenance of recast. Just like JSCodeshift it doesn’t evolve by time: if you want use it - fix bugs by yourself, add feature by yourself and maybe couple months or years after you PR will be merged.

I got AST enlightenment 🧘🏽‍♂️ and understand that I have all the knowledges to write my own printer, which I’ll support with a pleasure:

• ✅ It is based on Babel receives AST and returns string with well-formatted JavaScript code.
• ✅ It is highly opinionated but has two kind of options to have control over formatting.
• ✅ The options called format used to override output characters.
• ✅ The options called semantic used to override logic of formatting.
• ✅ This is something on the middle of ESLint and Recast but: faster and more low level - the best of two worlds.
• ✅ Easily expandable with two kinds of plugins support to extend formatting to any syntax you like.
• ✅ Has 🐊Putout plugin @putout/plugin-printer to simplify development.

@putout/printer is built-in to 🐊Putout, so you have ability to gain full control of your source code with no additional linters and formatters needed.

☢️ BREAKING CHANGE

Printer

recast no longer used as default printer, so if you want it for some reason update .putout.json with:

{
    "printer": "recast"
}

remove-useless-variables/await moved to promises/remove-useless-variables

If you disabled this rule, change your .putout.json with:

{
    "rules": {
-       "remove-useless-variables/await": "off",
+       "promises/remove-useless-variables": "off"
    }
}

❌ Example of incorrect code

async () => {
    const result = transformer.transform(realTransformer, transformCode, code, parser);
    const result2 = await Promise.resolve(result);
    
    return result2;
};

✅ Example of correct code

async () => {
    const result = transformer.transform(realTransformer, transformCode, code, parser);    
    return result;
};

@putout/minify

Actually formatting code is not the only feature of @putout/printer, it is also used for minification with @putout/plugin-minify, a plugin that contains a lot of rules to make code as small as possible.

git status --porcelain

Just got rid of isomorphic-git, and switched to a library I worked year ago: @putout/git-status-porcelain to implement --staged flag which works on a similar to lint-staged way: lint only changed files.

git-status-porcelain get names of files that was:

• ✅ modified;
• ✅ added;
• ✅ renamed;

in your git repository. Also after changing some of these files it helps us to add them back to staged state so they was ready to be committed easily with:

git commit -m '🔥🐊'

So now putout --staged --fix works about 10 times faster since everything is made by git it has very interesting text format that is easy to parse. It contains a 3-characters length string that consists of a couple big characters and space, like:

• M - modified;
• MM - modified, staged and then changed;
• R - renamed;

With this information you can get the most important information without any parsing of binary files and filtering all the results using JavaScript. This is a slow process, and latest release of isomorphic-git just made --staged speed about 100 times slower. Now it works about 10 times faster 😏.

simplify-boolean-return

A couple linters started to suggest me to modify my code this way:

-if (a)
-    return true;
-
-return false;
+return a;

I’m not sure how much this code becames more readable but cognitive load becomes less on one IfStatement, and there is less to run and less to read, so for you to decide🤷 (but you should know that I just updated my codebases with this rule 😏) if you don’t need it update your .putout.json with:

{
    "rules": {
        "simplify-boolean-return": "off"
    }
}

That's all for today 🦏!
