Initial implementation, CHANGELOG to follow.

Benchmark used:

pyperf timeit -g -s "from attr import make_class, attrib; A = make_class('A', ['a', 'b', 'c', 'd', 'e']); a = A(1, 2, 3, 4, 5)" "repr(a)"

Old code:

Mean +- std dev: 2.09 us +- 0.07 us

New code:

Mean +- std dev: 957 ns +- 27 ns

Looks like you’ll need a conditionally imported repr_fstrings.py or something.

I think it just means I can't use f-strings while preparing the function. I can just use string concatenation or .format() instead, not a big deal.

Still getting a depressing amount of Python 2 downloads 😢

The current versions that still support Python 2 won’t go away. :)

Many of the new features are related to Python-3-only features (e.g., typing, pattern matching) and are not benefical for Python 2 users anyways. So I don’t realy see the problem with new versions only supporting python 3.6 (or 3.7) upwards. :)

@hynek I don't understand the problem though, I don't think I touched that line?

Looks like one more line: https://codecov.io/gh/python-attrs/attrs/src/f37fc134b66c14b03a09fc09ca59f188537e1911/src/attr/_make.py#L1976

Hm, if I remove this, 3.5 and 3.6 start failing.

Guess we have to add 3.6 to coverage then

let's just yolo it

I haven't spent super much time understanding it, because the tests are passing so it should be fine. #yolo

But I'd like to avoid snail-formatting in new code (maybe should be adding to the contribution guide), so let's not do it. :)

What's snail-formatting btw?

No, snail formatting is what I call str.format() because it's slow as a snail. :D 🐌

Modulo + tuple is the second fastest approach.

465: build(deps): bump attrs from 21.2.0 to 21.3.0 r=ChrisRBe a=dependabot[bot]

Bumps [attrs](https://github.com/python-attrs/attrs) from 21.2.0 to 21.3.0.
<details>
<summary>Release notes</summary>
<p><em>Sourced from <a href="https://github.com/python-attrs/attrs/releases">attrs's releases</a>.</em></p>
<blockquote>
<h2>21.3.0</h2>
<p>This is a big release in the history of <code>attrs</code> and finishes an arc that took way too long and also delayed this very overdue release. But it's done: <code>import attrs</code> that has been talked about for years[^issue], but fell victim to “just this one more thing” has <em>finally</em> landed.</p>
<p>From now on, modern <code>attrs</code> code looks like this:</p>
<pre lang="python"><code>from attrs import define
<p><a href="https://github.com/define"><code>`@​define</code></a>`
class HelloWorld:
modern: bool = True
</code></pre></p>
<p>The <code>define</code>/<code>field</code> APIs have been around for over a year and were very popular, now the rest of the package followed suit. I'm very excited that <code>attrs</code> remains relevant and keeps evolving over now more than half a decade. If you're curious about some of the background, the docs now contain a short <a href="https://www.attrs.org/en/stable/names.html">explanation and history lesson</a>. As long as our users keep pushing us, we will keep pushing forward class generation in Python!</p>
<p>Big thanks to my <a href="https://github.com/sponsors/hynek/dashboard">GitHub Sponsors</a>, <a href="https://tidelift.com/subscription/pkg/pypi-attrs?utm_source=pypi-attrs&amp;utm_medium=referral&amp;utm_campaign=enterprise&amp;utm_term=repo">Tidelift subscribers</a>, and <a href="https://ko-fi.com/the_hynekl">Ko-fi buyers</a> that help me mustering the motivation for such long-running project!</p>
<hr />
<p>Since the release took so long, there's more highlights than we can enumerate here, we'd just like to point out a breaking change in the new APIs: converters now run on setting attributes by default. If this is causing problems to you, you can disable that behavior by setting <code>`@define(on_setattr=[])</code>.</p>`
<p>[^issue]:  I have an issue from 2018 that I wanted to &quot;come back the moment this lands&quot;.</p>
<h1>Full Changelog</h1>
<h2>Backward-incompatible Changes</h2>
<ul>
<li>
<p>When using <code>`@define</code>,` converters are now run by default when setting an attribute on an instance -- additionally to validators. I.e. the new default is <code>on_setattr=[attrs.setters.convert, attrs.setters.validate]</code>.</p>
<p>This is unfortunately a breaking change, but it was an oversight, impossible to raise a <code>DeprecationWarning</code> about, and it's better to fix it now while the APIs are very fresh with few users. <a href="https://github-redirect.dependabot.com/python-attrs/attrs/issues/835">#835</a>, <a href="https://github-redirect.dependabot.com/python-attrs/attrs/issues/886">#886</a></p>
</li>
<li>
<p><code>import attrs</code> has finally landed! As of this release, you can finally import <code>attrs</code> using its proper name.</p>
<p>Not all names from the <code>attr</code> namespace have been transferred; most notably <code>attr.s</code> and <code>attr.ib</code> are missing. See <code>attrs.define</code> and <code>attrs.field</code> if you haven't seen our next-generation APIs yet. A more elaborate explanation can be found <a href="https://www.attrs.org/en/latest/names.html">On The Core API Names</a></p>
<p>This feature is at least for one release <strong>provisional</strong>. We don't <em>plan</em> on changing anything, but such a big change is unlikely to go perfectly on the first strike.</p>
<p>The API docs have been mostly updated, but it will be an ongoing effort to change everything to the new APIs. Please note that we have <strong>not</strong> moved -- or even removed -- anything from <code>attr</code>!</p>
<p>Please do report any bugs or documentation inconsistencies! <a href="https://github-redirect.dependabot.com/python-attrs/attrs/issues/887">#887</a></p>

<h2>21.3.0</h2>
<p>This is a big release in the history of <code>attrs</code> and finishes an arc that took way too long and also delayed this very overdue release. But it's done: <code>import attrs</code> that has been talked about for years[^issue], but fell victim to “just this one more thing” has <em>finally</em> landed.</p>
<p>From now on, modern <code>attrs</code> code looks like this:</p>
<pre lang="python"><code>from attrs import define
<p><a href="https://github.com/define"><code>`@​define</code></a>`
class HelloWorld:
modern: bool = True
</code></pre></p>
<p>The <code>define</code>/<code>field</code> APIs have been around for over a year and were very popular, now the rest of the package followed suit. I'm very excited that <code>attrs</code> remains relevant and keeps evolving over now more than half a decade. If you're curious about some of the background, the docs now contain a short <a href="https://www.attrs.org/en/stable/names.html">explanation and history lesson</a>. As long as our users keep pushing us, we will keep pushing forward class generation in Python!</p>
<p>Big thanks to my <a href="https://github.com/sponsors/hynek/dashboard">GitHub Sponsors</a>, <a href="https://tidelift.com/subscription/pkg/pypi-attrs?utm_source=pypi-attrs&amp;utm_medium=referral&amp;utm_campaign=enterprise&amp;utm_term=repo">Tidelift subscribers</a>, and <a href="https://ko-fi.com/the_hynekl">Ko-fi buyers</a> that help me mustering the motivation for such long-running project!</p>
<hr />
<p>Since the release took so long, there's more highlights than we can enumerate here, we'd just like to point out a breaking change in the new APIs: converters now run on setting attributes by default. If this is causing problems to you, you can disable that behavior by setting <code>`@define(on_setattr=[])</code>.</p>`
<p>[^issue]:  I have an issue from 2018 that I wanted to &quot;come back the moment this lands&quot;.</p>
<h1>Full Changelog</h1>
<h2>Backward-incompatible Changes</h2>
<ul>
<li>
<p>When using <code>`@define</code>,` converters are now run by default when setting an attribute on an instance -- additionally to validators. I.e. the new default is <code>on_setattr=[attrs.setters.convert, attrs.setters.validate]</code>.</p>
<p>This is unfortunately a breaking change, but it was an oversight, impossible to raise a <code>DeprecationWarning</code> about, and it's better to fix it now while the APIs are very fresh with few users. <a href="https://github-redirect.dependabot.com/python-attrs/attrs/issues/835">#835</a>, <a href="https://github-redirect.dependabot.com/python-attrs/attrs/issues/886">#886</a></p>

<h2>21.3.0 (2021-12-28)</h2>
<p>Backward-incompatible Changes
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^</p>
<ul>
<li>
<p>When using <code>@define</code>, converters are now run by default when setting an attribute on an instance -- additionally to validators.
I.e. the new default is <code>on_setattr=[attrs.setters.convert, attrs.setters.validate]</code>.</p>
<p>This is unfortunately a breaking change, but it was an oversight, impossible to raise a <code>DeprecationWarning</code> about, and it's better to fix it now while the APIs are very fresh with few users.

As of this release, you can finally import <code>attrs</code> using its proper name.</p>
<p>Not all names from the <code>attr</code> namespace have been transferred; most notably <code>attr.s</code> and <code>attr.ib</code> are missing.

<summary>Release notes</summary>
<p><em>Sourced from <a href="https://github.com/python-attrs/attrs/releases">attrs's releases</a>.</em></p>
<blockquote>
<h2>21.3.0</h2>
<p>This is a big release in the history of <code>attrs</code> and finishes an arc that took way too long and also delayed this very overdue release. But it's done: <code>import attrs</code> that has been talked about for years[^issue], but fell victim to “just this one more thing” has <em>finally</em> landed.</p>
<p>From now on, modern <code>attrs</code> code looks like this:</p>
<pre lang="python"><code>from attrs import define
<p><a href="https://github.com/define"><code>`@​define</code></a>`
class HelloWorld:
modern: bool = True
</code></pre></p>
<p>The <code>define</code>/<code>field</code> APIs have been around for over a year and were very popular, now the rest of the package followed suit. I'm very excited that <code>attrs</code> remains relevant and keeps evolving over now more than half a decade. If you're curious about some of the background, the docs now contain a short <a href="https://www.attrs.org/en/stable/names.html">explanation and history lesson</a>. As long as our users keep pushing us, we will keep pushing forward class generation in Python!</p>
<p>Big thanks to my <a href="https://github.com/sponsors/hynek/dashboard">GitHub Sponsors</a>, <a href="https://tidelift.com/subscription/pkg/pypi-attrs?utm_source=pypi-attrs&amp;utm_medium=referral&amp;utm_campaign=enterprise&amp;utm_term=repo">Tidelift subscribers</a>, and <a href="https://ko-fi.com/the_hynekl">Ko-fi buyers</a> that help me mustering the motivation for such long-running project!</p>
<hr />
<p>Since the release took so long, there's more highlights than we can enumerate here, we'd just like to point out a breaking change in the new APIs: converters now run on setting attributes by default. If this is causing problems to you, you can disable that behavior by setting <code>`@define(on_setattr=[])</code>.</p>`
<p>[^issue]:  I have an issue from 2018 that I wanted to &quot;come back the moment this lands&quot;.</p>

<blockquote>
<h2>21.3.0</h2>
<p>This is a big release in the history of <code>attrs</code> and finishes an arc that took way too long and also delayed this very overdue release. But it's done: <code>import attrs</code> that has been talked about for years[^issue], but fell victim to “just this one more thing” has <em>finally</em> landed.</p>
<p>From now on, modern <code>attrs</code> code looks like this:</p>
<pre lang="python"><code>from attrs import define
<p><a href="https://github.com/define"><code>`@​define</code></a>`
class HelloWorld:
modern: bool = True
</code></pre></p>
<p>The <code>define</code>/<code>field</code> APIs have been around for over a year and were very popular, now the rest of the package followed suit. I'm very excited that <code>attrs</code> remains relevant and keeps evolving over now more than half a decade. If you're curious about some of the background, the docs now contain a short <a href="https://www.attrs.org/en/stable/names.html">explanation and history lesson</a>. As long as our users keep pushing us, we will keep pushing forward class generation in Python!</p>
<p>Big thanks to my <a href="https://github.com/sponsors/hynek/dashboard">GitHub Sponsors</a>, <a href="https://tidelift.com/subscription/pkg/pypi-attrs?utm_source=pypi-attrs&amp;utm_medium=referral&amp;utm_campaign=enterprise&amp;utm_term=repo">Tidelift subscribers</a>, and <a href="https://ko-fi.com/the_hynekl">Ko-fi buyers</a> that help me mustering the motivation for such long-running project!</p>
<hr />
<p>Since the release took so long, there's more highlights than we can enumerate here, we'd just like to point out a breaking change in the new APIs: converters now run on setting attributes by default. If this is causing problems to you, you can disable that behavior by setting <code>`@define(on_setattr=[])</code>.</p>`
<p>[^issue]:  I have an issue from 2018 that I wanted to &quot;come back the moment this lands&quot;.</p>
<h1>Full Changelog</h1>
<h2>Backward-incompatible Changes</h2>
<ul>
<li>
<p>When using <code>`@define</code>,` converters are now run by default when setting an attribute on an instance -- additionally to validators. I.e. the new default is <code>on_setattr=[attrs.setters.convert, attrs.setters.validate]</code>.</p>
<p>This is unfortunately a breaking change, but it was an oversight, impossible to raise a <code>DeprecationWarning</code> about, and it's better to fix it now while the APIs are very fresh with few users. <a href="https://github-redirect.dependabot.com/python-attrs/attrs/issues/835">#835</a>, <a href="https://github-redirect.dependabot.com/python-attrs/attrs/issues/886">#886</a></p>
</li>
<li>
<p><code>import attrs</code> has finally landed! As of this release, you can finally import <code>attrs</code> using its proper name.</p>
<p>Not all names from the <code>attr</code> namespace have been transferred; most notably <code>attr.s</code> and <code>attr.ib</code> are missing. See <code>attrs.define</code> and <code>attrs.field</code> if you haven't seen our next-generation APIs yet. A more elaborate explanation can be found <a href="https://www.attrs.org/en/latest/names.html">On The Core API Names</a></p>
<p>This feature is at least for one release <strong>provisional</strong>. We don't <em>plan</em> on changing anything, but such a big change is unlikely to go perfectly on the first strike.</p>
<p>The API docs have been mostly updated, but it will be an ongoing effort to change everything to the new APIs. Please note that we have <strong>not</strong> moved -- or even removed -- anything from <code>attr</code>!</p>
<p>Please do report any bugs or documentation inconsistencies! <a href="https://github-redirect.dependabot.com/python-attrs/attrs/issues/887">#887</a></p>
