- <h2 id="formatting-tools"><a class="header" href="#formatting-tools">Formatting tools</a></h2>
- <p>The Synapse codebase uses a number of code formatting tools in order to
- quickly and automatically check for formatting (and sometimes logical)
- errors in code.</p>
- <p>The necessary tools are detailed below.</p>
- <p>First install them with:</p>
- <pre><code class="language-sh">pip install -e ".[lint,mypy]"
- </code></pre>
- <ul>
- <li>
- <p><strong>black</strong></p>
- <p>The Synapse codebase uses <a href="https://pypi.org/project/black/">black</a>
- as an opinionated code formatter, ensuring all comitted code is
- properly formatted.</p>
- <p>Have <code>black</code> auto-format your code (it shouldn't change any
- functionality) with:</p>
- <pre><code class="language-sh">black . --exclude="\.tox|build|env"
- </code></pre>
- </li>
- <li>
- <p><strong>flake8</strong></p>
- <p><code>flake8</code> is a code checking tool. We require code to pass <code>flake8</code>
- before being merged into the codebase.</p>
- <p>Check all application and test code with:</p>
- <pre><code class="language-sh">flake8 synapse tests
- </code></pre>
- </li>
- <li>
- <p><strong>isort</strong></p>
- <p><code>isort</code> ensures imports are nicely formatted, and can suggest and
- auto-fix issues such as double-importing.</p>
- <p>Auto-fix imports with:</p>
- <pre><code class="language-sh">isort -rc synapse tests
- </code></pre>
- <p><code>-rc</code> means to recursively search the given directories.</p>
- </li>
- </ul>
- <p>It's worth noting that modern IDEs and text editors can run these tools
- automatically on save. It may be worth looking into whether this
- functionality is supported in your editor for a more convenient
- development workflow. It is not, however, recommended to run <code>flake8</code> on
- save as it takes a while and is very resource intensive.</p>
- <h2 id="general-rules"><a class="header" href="#general-rules">General rules</a></h2>
- <ul>
- <li><strong>Naming</strong>:
- <ul>
- <li>Use camel case for class and type names</li>
- <li>Use underscores for functions and variables.</li>
- </ul>
- </li>
- <li><strong>Docstrings</strong>: should follow the <a href="https://google.github.io/styleguide/pyguide.html#38-comments-and-docstrings">google code
- style</a>.
- See the
- <a href="http://sphinxcontrib-napoleon.readthedocs.io/en/latest/example_google.html">examples</a>
- in the sphinx documentation.</li>
- <li><strong>Imports</strong>:
- <ul>
- <li>
- <p>Imports should be sorted by <code>isort</code> as described above.</p>
- </li>
- <li>
- <p>Prefer to import classes and functions rather than packages or
- modules.</p>
- <p>Example:</p>
- <pre><code class="language-python">from synapse.types import UserID
- ...
- user_id = UserID(local, server)
- </code></pre>
- <p>is preferred over:</p>
- <pre><code class="language-python">from synapse import types
- ...
- user_id = types.UserID(local, server)
- </code></pre>
- <p>(or any other variant).</p>
- <p>This goes against the advice in the Google style guide, but it
- means that errors in the name are caught early (at import time).</p>
- </li>
- <li>
- <p>Avoid wildcard imports (<code>from synapse.types import *</code>) and
- relative imports (<code>from .types import UserID</code>).</p>
- </li>
- </ul>
- </li>
- </ul>
- <h2 id="configuration-file-format"><a class="header" href="#configuration-file-format">Configuration file format</a></h2>
- <p>The <a href="./sample_config.yaml">sample configuration file</a> acts as a
- reference to Synapse's configuration options for server administrators.
- Remember that many readers will be unfamiliar with YAML and server
- administration in general, so that it is important that the file be as
- easy to understand as possible, which includes following a consistent
- format.</p>
- <p>Some guidelines follow:</p>
- <ul>
- <li>
- <p>Sections should be separated with a heading consisting of a single
- line prefixed and suffixed with <code>##</code>. There should be <strong>two</strong> blank
- lines before the section header, and <strong>one</strong> after.</p>
- </li>
- <li>
- <p>Each option should be listed in the file with the following format:</p>
- <ul>
- <li>
- <p>A comment describing the setting. Each line of this comment
- should be prefixed with a hash (<code>#</code>) and a space.</p>
- <p>The comment should describe the default behaviour (ie, what
- happens if the setting is omitted), as well as what the effect
- will be if the setting is changed.</p>
- <p>Often, the comment end with something like "uncomment the
- following to <do action>".</p>
- </li>
- <li>
- <p>A line consisting of only <code>#</code>.</p>
- </li>
- <li>
- <p>A commented-out example setting, prefixed with only <code>#</code>.</p>
- <p>For boolean (on/off) options, convention is that this example
- should be the <em>opposite</em> to the default (so the comment will end
- with "Uncomment the following to enable [or disable]
- <feature>." For other options, the example should give some
- non-default value which is likely to be useful to the reader.</p>
- </li>
- </ul>
- </li>
- <li>
- <p>There should be a blank line between each option.</p>
- </li>
- <li>
- <p>Where several settings are grouped into a single dict, <em>avoid</em> the
- convention where the whole block is commented out, resulting in
- comment lines starting <code># #</code>, as this is hard to read and confusing
- to edit. Instead, leave the top-level config option uncommented, and
- follow the conventions above for sub-options. Ensure that your code
- correctly handles the top-level option being set to <code>None</code> (as it
- will be if no sub-options are enabled).</p>
- </li>
- <li>
- <p>Lines should be wrapped at 80 characters.</p>
- </li>
- <li>
- <p>Use two-space indents.</p>
- </li>
- <li>
- <p><code>true</code> and <code>false</code> are spelt thus (as opposed to <code>True</code>, etc.)</p>
- </li>
- <li>
- <p>Use single quotes (<code>'</code>) rather than double-quotes (<code>"</code>) or backticks
- (<code>`</code>) to refer to configuration options.</p>
- </li>
- </ul>
- <p>Example:</p>
- <pre><code class="language-yaml">## Frobnication ##
- # The frobnicator will ensure that all requests are fully frobnicated.
- # To enable it, uncomment the following.
- #
- #frobnicator_enabled: true
- # By default, the frobnicator will frobnicate with the default frobber.
- # The following will make it use an alternative frobber.
- #
- #frobincator_frobber: special_frobber
- # Settings for the frobber
- #
- frobber:
- # frobbing speed. Defaults to 1.
- #
- #speed: 10
- # frobbing distance. Defaults to 1000.
- #
- #distance: 100
- </code></pre>
- <p>Note that the sample configuration is generated from the synapse code
- and is maintained by a script, <code>scripts-dev/generate_sample_config</code>.
- Making sure that the output from this script matches the desired format
- is left as an exercise for the reader!</p>
