From: Lady Date: Sat, 22 Jun 2024 17:02:24 +0000 (-0400) Subject: Generate dependencies & destinations with metadata X-Git-Tag: 0.11.1~2 X-Git-Url: https://git.ladys.computer/Shushe/commitdiff_plain/be24d75be02ad626c13c0b52cdc30e2ef8735c9f Generate dependencies & destinations with metadata This commit obviates the need for separate `metadata2dependencies` and `metadata2destinations` transforms and simply bundles their functionality into `expandmetadata`. Making this work right is a bit tricky because we are outputting the main document to `stdout` but want the other result documents to be output to `BUILDDIR`. The best solution would be to just read in the build directory inside of the transform and use it to determine the output location, but unfortunately `exsl:document` does not support dynamic computation of the destination directory. The current solution is instead to `cd` into the build directory in a subshell before calling `xsltproc`. --- diff --git a/GNUmakefile b/GNUmakefile index 3c49432..a41fb96 100644 --- a/GNUmakefile +++ b/GNUmakefile @@ -571,12 +571,12 @@ FORCE : ;
