<html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8"></head><body style="word-wrap: break-word; -webkit-nbsp-mode: space; line-break: after-white-space;" class="">I have recently been building up some relatively large package trees (for example, porting Boost to build with SwiftPM).<div class=""><br class=""></div><div class="">The way I do this is that locally I use remote URLs which are relative to the source package. This lets me iterate very quickly without needing to push to an origin. Of course, it doesn’t work when pushing them to an actual SCM server.</div><div class=""><br class=""></div><div class="">However, what if we allowed relative-path URLs to be resolved relative to the <b class="">origin</b> from which SwiftPM found them? Concretely:</div><div class=""><br class=""></div><div class="">If I have:</div><div class=""> <a href="http://github.com/ddunbar/foo" class="">github.com/ddunbar/foo</a></div><div class="">and it’s Package.swift has:</div><div class=""> dependencies: [.package(url: “../bar”, …)]</div><div class="">then the idea is to make SwiftPM resolve ../bar to be <a href="http://github.com/dunbar/bar" class="">github.com/dunbar/bar</a>, which happens to be exactly what I want.</div><div class=""><br class=""></div><div class="">This even works for absolute path URLs, the other URL components would come from the origin, so I could also reference:</div><div class=""> dependencies: [.package(url: “/apple/swift-package-manager”)]</div><div class="">if I wanted to depend on SwiftPM.</div><div class=""><br class=""></div><div class="">One really nice thing about this scheme is that it simplifies mirroring of trees of packages. For example, if I wanted to clone the above examples onto, say, an enterprise SCM server, then as long as I cloned all of them into the same relative organization, I wouldn’t need to rewrite any of the URL references in the packages themselves during the clone.</div><div class=""><br class=""></div><div class="">Thoughts?</div><div class=""><div class=""> - Daniel</div></div></body></html>
