From 4fd061c426902b0904c65e64a3780b21f9ab3afb Mon Sep 17 00:00:00 2001 From: Alex Crichton Date: Wed, 18 Sep 2013 22:18:38 -0700 Subject: [PATCH] Implement a web backend for rustdoc_ng This large commit implements and `html` output option for rustdoc_ng. The executable has been altered to be invoked as "rustdoc_ng html " and it will dump everything into the local "doc" directory. JSON can still be generated by changing 'html' to 'json'. This also fixes a number of bugs in rustdoc_ng relating to comment stripping, along with some other various issues that I found along the way. The `make doc` command has been altered to generate the new documentation into the `doc/ng/$(CRATE)` directories. --- RELEASES.txt | 1 + mk/docs.mk | 15 + src/libextra/extra.rs | 4 + src/libstd/macros.rs | 1 + src/libstd/num/int_macros.rs | 1 + src/libstd/num/uint_macros.rs | 1 + src/libstd/rt/mod.rs | 3 +- src/libstd/std.rs | 4 + src/libsyntax/ext/format.rs | 2 +- src/libsyntax/parse/comments.rs | 4 +- src/rustdoc_ng/clean.rs | 55 +- src/rustdoc_ng/fold.rs | 20 +- src/rustdoc_ng/html/format.rs | 364 ++++++ src/rustdoc_ng/html/layout.rs | 130 ++ src/rustdoc_ng/html/markdown.rs | 54 + src/rustdoc_ng/html/render.rs | 1108 +++++++++++++++++ .../html/static/jquery-2.0.3.min.js | 6 + src/rustdoc_ng/html/static/main.css | 270 ++++ src/rustdoc_ng/html/static/main.js | 420 +++++++ src/rustdoc_ng/html/static/normalize.css | 396 ++++++ src/rustdoc_ng/passes.rs | 174 +-- src/rustdoc_ng/rustdoc_ng.rs | 161 ++- 22 files changed, 3061 insertions(+), 133 deletions(-) create mode 100644 src/rustdoc_ng/html/format.rs create mode 100644 src/rustdoc_ng/html/layout.rs create mode 100644 src/rustdoc_ng/html/markdown.rs create mode 100644 src/rustdoc_ng/html/render.rs create mode 100644 src/rustdoc_ng/html/static/jquery-2.0.3.min.js create mode 100644 src/rustdoc_ng/html/static/main.css create mode 100644 src/rustdoc_ng/html/static/main.js create mode 100644 src/rustdoc_ng/html/static/normalize.css diff --git a/RELEASES.txt b/RELEASES.txt index a65c0c22142ce..328b783121dee 100644 --- a/RELEASES.txt +++ b/RELEASES.txt @@ -142,6 +142,7 @@ Version 0.8 (October 2013) * The runtime uses jemalloc for allocations. * Segmented stacks are temporarily disabled as part of the transition to the new runtime.
