<aname="hacking--dependencies"></a><h3class="show-anchors"><div>Dependencies<divclass="anchors"><aclass="self"href="/v5/hacking/#hacking--dependencies"></a></div></div></h3><p>Adding a dependency is non-trivial and will require fairly convincing arguments.</p>
<p>Further, <b>ALL</b> dependencies for ethers, <b>must</b> be MIT licensed or public domain (CC0).</p>
<p>All contributions to ethers are then included under the MIT license.</p>

<p>This is for several reasons, bu...</p>
<p><ul><li>Transmission over certain HTTP servers and proxies can mangle UTF-8 data </li><li>Certain editors on some platforms, or in certain terminals cannot handle UTF-8 characters elegantly </li><li>The ability to enter non-ASCII characters on some platforms require special keyboards, input devices or input methods to be installed, which either not be supported, or may require administrative priviledges. </li></ul></p>

<p>It is important to remember that a small change is something that we are required to support in perpetuity.</p>
<p>For example, adding support for an obscure platform, such as adding a dot-file to the root of the package, now carries the implication that we will continue keeping that dot-file up-to-date as new versions of that platform are released.</p>
