This will make it easier for reviewers to distinguish from your changes and formatting fixes.</p> <p>If your team agrees to a consistent formatting logic, sticks to it and always remembers to run the linting/fixing tools you should not have anything to change. But thats not what this post is about, its about the real world. People forget to run linters, some don't care, some may not even be aware of the teams formatting guidelines. Talk to your team about these things and get on the same page.</p> <p>I care about formatting, we all should. We want to put out the best work we can in our craft. Realistically though I dont really care about nit picky stuff, I just want things consistant so that it makes things easier to read without me taking the time to swap out quotes, and fix line spacing. I want a tool to do it for me, and when that tool runs I dont want it mixing in the same commit as my work.</p> <pre><code>black . git add . git commit -m "FIX formatted with black" </code></pre> <h3>Work<a alt="id" class="heading-permalink" href="#None" title="link to #None"><span class="visually-hidden"></span><svg aria-hidden="true" fill="currentColor" focusable="false" height="1em" viewBox="0 0 24 24" width="1em" xmlns="http://www.w3.org/2000/svg"><path d="M9.199 13.599a5.99 5.99 0 0 0 3.949 2.345 5.987 5.987 0 0 0 5.105-1.702l2.995-2.994a5.992 5.992 0 0 0 1.695-4.285 5.976 5.976 0 0 0-1.831-4.211 5.99 5.99 0 0 0-6.431-1.242 6.003 6.003 0 0 0-1.905 1.24l-1.731 1.721a.999.999 0 1 0 1.41 1.418l1.709-1.699a3.985 3.985 0 0 1 2.761-1.123 3.975 3.975 0 0 1 2.799 1.122 3.997 3.997 0 0 1 .111 5.644l-3.005 3.006a3.982 3.982 0 0 1-3.395 1.126 3.987 3.987 0 0 1-2.632-1.563A1 1 0 0 0 9.201 13.6zm5.602-3.198a5.99 5.99 0 0 0-3.949-2.345 5.987 5.987 0 0 0-5.105 1.702l-2.995 2.994a5.992 5.992 0 0 0-1.695 4.285 5.976 5.976 0 0 0 1.831 4.211 5.99 5.99 0 0 0 6.431 1.242 6.003 6.003 0 0 0 1.905-1.24l1.723-1.723a.999.999 0 1 0-1.414-1.414L9.836 19.81a3.985 3.985 0 0 1-2.761 1.123 3.975 3.975 0 0 1-2.799-1.122 3.997 3.997 0 0 1-.111-5.644l3.005-3.006a3.982 3.982 0 0 1 3.395-1.126 3.987 3.987 0 0 1 2.632 1.563 1 1 0 0 0 1.602-1.198z"></path></svg></a></h3> <p>Make your changes to your code, test them, document them, clean it up, do what you do best.</p> <h3>add and commit<a alt="id" class="heading-permalink" href="#None" title="link to #None"><span class="visually-hidden"></span><svg aria-hidden="true" fill="currentColor" focusable="false" height="1em" viewBox="0 0 24 24" width="1em" xmlns="http://www.w3.org/2000/svg"><path d="M9.199 13.599a5.99 5.99 0 0 0 3.949 2.345 5.987 5.987 0 0 0 5.105-1.702l2.995-2.994a5.992 5.992 0 0 0 1.695-4.285 5.976 5.976 0 0 0-1.831-4.211 5.99 5.99 0 0 0-6.431-1.242 6.003 6.003 0 0 0-1.905 1.24l-1.731 1.721a.999.999 0 1 0 1.41 1.418l1.709-1.699a3.985 3.985 0 0 1 2.761-1.123 3.975 3.975 0 0 1 2.799 1.122 3.997 3.997 0 0 1 .111 5.644l-3.005 3.006a3.982 3.982 0 0 1-3.395 1.126 3.987 3.987 0 0 1-2.632-1.563A1 1 0 0 0 9.201 13.6zm5.602-3.198a5.99 5.99 0 0 0-3.949-2.345 5.987 5.987 0 0 0-5.105 1.702l-2.995 2.994a5.992 5.992 0 0 0-1.695 4.285 5.976 5.976 0 0 0 1.831 4.211 5.99 5.99 0 0 0 6.431 1.242 6.003 6.003 0 0 0 1.905-1.24l1.723-1.723a.999.999 0 1 0-1.414-1.414L9.836 19.81a3.985 3.985 0 0 1-2.761 1.123 3.975 3.975 0 0 1-2.799-1.122 3.997 3.997 0 0 1-.111-5.644l3.005-3.006a3.982 3.982 0 0 1 3.395-1.126 3.987 3.987 0 0 1 2.632 1.563 1 1 0 0 0 1.602-1.198z"></path></svg></a></h3> <p>Next you will need to stage files that have changed for commit, and commit them.

Your approver may have an idea to clean it up to make it more readable/maintainable, or something to make it more performant. Remember that a second set of eyes sometimes has a new set of clarity that you do not as you have seen the work from start to end.

For this particular pitfall I prefer to <strong><code>rebase</code></strong>. When you look at the git log and commit history it will appear as if you made your changes after everyone else made theirs. I do this to clean up the PR and make it easier for the approver to read. There will be less merge commits, and less history to try to understand.</p> <p><strong>Before pushing to the remote repository</strong></p> <pre class="wrapper"> <div class="copy-wrapper"> <button class="copy" onclick="navigator.clipboard.writeText(this.parentElement.parentElement.querySelector('pre').textContent)" title="copy code to clipboard"><svg id="Layer_1" style="enable-background:new 0 0 115.77 122.88" version="1.1" viewbox="0 0 115.77 122.88" x="0px" xml:space="preserve" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" y="0px"><style type="text/css">.st0{fill-rule:evenodd;clip-rule:evenodd;}</style><g><path class="st0" d="M89.62,13.96v7.73h12.19h0.01v0.02c3.85,0.01,7.34,1.57,9.86,4.1c2.5,2.51,4.06,5.98,4.07,9.82h0.02v0.02 v73.27v0.01h-0.02c-0.01,3.84-1.57,7.33-4.1,9.86c-2.51,2.5-5.98,4.06-9.82,4.07v0.02h-0.02h-61.7H40.1v-0.02 c-3.84-0.01-7.34-1.57-9.86-4.1c-2.5-2.51-4.06-5.98-4.07-9.82h-0.02v-0.02V92.51H13.96h-0.01v-0.02c-3.84-0.01-7.34-1.57-9.86-4.1 c-2.5-2.51-4.06-5.98-4.07-9.82H0v-0.02V13.96v-0.01h0.02c0.01-3.85,1.58-7.34,4.1-9.86c2.51-2.5,5.98-4.06,9.82-4.07V0h0.02h61.7 h0.01v0.02c3.85,0.01,7.34,1.57,9.86,4.1c2.5,2.51,4.06,5.98,4.07,9.82h0.02V13.96L89.62,13.96z M79.04,21.69v-7.73v-0.02h0.02 c0-0.91-0.39-1.75-1.01-2.37c-0.61-0.61-1.46-1-2.37-1v0.02h-0.01h-61.7h-0.02v-0.02c-0.91,0-1.75,0.39-2.37,1.01 c-0.61,0.61-1,1.46-1,2.37h0.02v0.01v64.59v0.02h-0.02c0,0.91,0.39,1.75,1.01,2.37c0.61,0.61,1.46,1,2.37,1v-0.02h0.01h12.19V35.65 v-0.01h0.02c0.01-3.85,1.58-7.34,4.1-9.86c2.51-2.5,5.98-4.06,9.82-4.07v-0.02h0.02H79.04L79.04,21.69z M105.18,108.92V35.65v-0.02 h0.02c0-0.91-0.39-1.75-1.01-2.37c-0.61-0.61-1.46-1-2.37-1v0.02h-0.01h-61.7h-0.02v-0.02c-0.91,0-1.75,0.39-2.37,1.01 c-0.61,0.61-1,1.46-1,2.37h0.02v0.01v73.27v0.02h-0.02c0,0.91,0.39,1.75,1.01,2.37c0.61,0.61,1.46,1,2.37,1v-0.02h0.01h61.7h0.02 v0.02c0.91,0,1.75-0.39,2.37-1.01c0.61-0.61,1-1.46,1-2.37h-0.02V108.92L105.18,108.92z"></path></g></svg></button> </div> <div class="highlight"><pre><span></span>git<span class="w"> </span>fetch<span class="w"> </span>--all <span class="c1"># or</span> git<span class="w"> </span>checkout<span class="w"> </span>develop git<span class="w"> </span>pull git<span class="w"> </span>checkout<span class="w"> </span>feature_branch <span class="c1"># then</span> git<span class="w"> </span>rebase<span class="w"> </span>develop </pre></div> </pre> <p><strong>if its your first rodeo</strong> or you are unsure how the rebase will go you can create a safty branch.</p> <pre class="wrapper"> <div class="copy-wrapper"> <button class="copy" onclick="navigator.clipboard.writeText(this.parentElement.parentElement.querySelector('pre').textContent)" title="copy code to clipboard"><svg id="Layer_1" style="enable-background:new 0 0 115.77 122.88" version="1.1" viewbox="0 0 115.77 122.88" x="0px" xml:space="preserve" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" y="0px"><style type="text/css">.st0{fill-rule:evenodd;clip-rule:evenodd;}</style><g><path class="st0" d="M89.62,13.96v7.73h12.19h0.01v0.02c3.85,0.01,7.34,1.57,9.86,4.1c2.5,2.51,4.06,5.98,4.07,9.82h0.02v0.02 v73.27v0.01h-0.02c-0.01,3.84-1.57,7.33-4.1,9.86c-2.51,2.5-5.98,4.06-9.82,4.07v0.02h-0.02h-61.7H40.1v-0.02 c-3.84-0.01-7.34-1.57-9.86-4.1c-2.5-2.51-4.06-5.98-4.07-9.82h-0.02v-0.02V92.51H13.96h-0.01v-0.02c-3.84-0.01-7.34-1.57-9.86-4.1 c-2.5-2.51-4.06-5.98-4.07-9.82H0v-0.02V13.96v-0.01h0.02c0.01-3.85,1.58-7.34,4.1-9.86c2.51-2.5,5.98-4.06,9.82-4.07V0h0.02h61.7 h0.01v0.02c3.85,0.01,7.34,1.57,9.86,4.1c2.5,2.51,4.06,5.98,4.07,9.82h0.02V13.96L89.62,13.96z M79.04,21.69v-7.73v-0.02h0.02 c0-0.91-0.39-1.75-1.01-2.37c-0.61-0.61-1.46-1-2.37-1v0.02h-0.01h-61.7h-0.02v-0.02c-0.91,0-1.75,0.39-2.37,1.01 c-0.61,0.61-1,1.46-1,2.37h0.02v0.01v64.59v0.02h-0.02c0,0.91,0.39,1.75,1.01,2.37c0.61,0.61,1.46,1,2.37,1v-0.02h0.01h12.19V35.65 v-0.01h0.02c0.01-3.85,1.58-7.34,4.1-9.86c2.51-2.5,5.98-4.06,9.82-4.07v-0.02h0.02H79.04L79.04,21.69z M105.18,108.92V35.65v-0.02 h0.02c0-0.91-0.39-1.75-1.01-2.37c-0.61-0.61-1.46-1-2.37-1v0.02h-0.01h-61.7h-0.02v-0.02c-0.91,0-1.75,0.39-2.37,1.01 c-0.61,0.61-1,1.46-1,2.37h0.02v0.01v73.27v0.02h-0.02c0,0.91,0.39,1.75,1.01,2.37c0.61,0.61,1.46,1,2.37,1v-0.02h0.01h61.7h0.02 v0.02c0.91,0,1.75-0.39,2.37-1.01c0.61-0.61,1-1.46,1-2.37h-0.02V108.92L105.18,108.92z"></path></g></svg></button> </div> <div class="highlight"><pre><span></span>git<span class="w"> </span>branch<span class="w"> </span>saftey_feature_branch git<span class="w"> </span>fetch<span class="w"> </span>--all git<span class="w"> </span>rebase<span class="w"> </span>develop git<span class="w"> </span>branch<span class="w"> </span>-D<span class="w"> </span>safety_feature_branch<span class="w"> </span><span class="c1"># deletes safety_feature_branch</span> </pre></div> </pre>
