From 8fb477a6e7ecb887761b73d4defeb75fca99e59c Mon Sep 17 00:00:00 2001 From: Valentin Gagarin Date: Mon, 27 Nov 2023 08:33:03 +0100 Subject: [PATCH] add path based redirects up to now, those were managed outside of this repo, which as unsurprisingly a real hassle to deal with if one wanted to prevent URLs from breaking when moving pages around. this change removes a large part of the friction involved in moving content in the Nix manual. possible next steps for further automation: - check for content that moved and warn if it's not reachable from links that were valid prior to a change - create redirect rules automatically based on this information (cherry picked from commit 2b7016cc56d12e67de9f1f25b18311866a26a5fe) --- doc/manual/_redirects | 30 ++++++++++++++++++++++++++++++ doc/manual/redirects.js | 8 +++++--- 2 files changed, 35 insertions(+), 3 deletions(-) create mode 100644 doc/manual/_redirects diff --git a/doc/manual/_redirects b/doc/manual/_redirects new file mode 100644 index 000000000..4ea289d86 --- /dev/null +++ b/doc/manual/_redirects @@ -0,0 +1,30 @@ +# redirect rules for paths (server-side) to prevent link rot. +# see ./redirects.js for redirects based on URL fragments (client-side) +# +# concrete user story this supports: +# - user finds URL to the manual for Nix x.y +# - Nix x.z (z > y) is the most recent release +# - updating the version in the URL will show the right thing +# +# format documentation: +# - https://docs.netlify.com/routing/redirects/#syntax-for-the-redirects-file +# - https://docs.netlify.com/routing/redirects/redirect-options/ +# +# conventions: +# - always force (!) since this allows re-using file names +# - group related paths to ease readability +# - always append new redirects to the end of the file +# - redirects that should have been there but are missing can be inserted where they belong + +/expressions/expression-language /language/ 301! +/expressions/language-values /language/values 301! +/expressions/language-constructs /language/constructs 301! +/expressions/language-operators /language/operators 301! +/expressions/* /language/:splat 301! + +/package-management/basic-package-mgmt /command-ref/nix-env 301! + +/package-management/channels* /command-ref/nix-channel 301! + +/package-management/s3-substituter* /command-ref/new-cli/nix3-help-stores#s3-binary-cache-store 301! + diff --git a/doc/manual/redirects.js b/doc/manual/redirects.js index b43622ed6..2ff446cdd 100644 --- a/doc/manual/redirects.js +++ b/doc/manual/redirects.js @@ -1,7 +1,9 @@ -// redirect rules for anchors ensure backwards compatibility of URLs. -// this must be done on the client side, as web servers do not see the anchor part of the URL. +// redirect rules for URL fragments (client-side) to prevent link rot. +// this must be done on the client side, as web servers do not see the fragment part of the URL. +// it will only work with JavaScript enabled in the browser, but this is the best we can do here. +// see ./_redirects for path redirects (client-side) -// redirections are declared as follows: +// redirects are declared as follows: // each entry has as its key a path matching the requested URL path, relative to the mdBook document root. // // IMPORTANT: it must specify the full path with file name and suffix
