Hi, While trying to tangle luatex.web, I found it necesseary to apply the following patch in order to fix what looks like two typos. diff --git a/source/texk/web2c/luatexdir/luatex.web b/source/texk/web2c/luatexdir/luatex.web index bfcf025..5f0eb64 100644 --- a/source/texk/web2c/luatexdir/luatex.web +++ b/source/texk/web2c/luatexdir/luatex.web @@ -5413,8 +5413,7 @@ primitive_tex("errhelp",assign_toks,err_help_loc,local_base); primitive_pdftex("pdfpagesattr",assign_toks,pdf_pages_attr_loc,local_base); @!@:pdf_pages_attr_}{\.{\\pdfpagesattr} primitive@> primitive_pdftex("pdfpageattr",assign_toks,pdf_page_attr_loc,local_base); -@!@:pdf_page_attr_}{\.{\\pdfpageattmooi -r} primitive@> +@!@:pdf_page_attr_}{\.{\\pdfpageattr} primitive@> primitive_pdftex("pdfpageresources",assign_toks,pdf_page_resources_loc,local_base); @!@:pdf_page_resources_}{\.{\\pdfpageresources} primitive@> primitive_pdftex("pdfpkmode",assign_toks,pdf_pk_mode_loc,local_base); @@ -21284,7 +21283,7 @@ node $r_j$ is followed by |r@t$_{j+1}$@>=vlink(r@t$_j$@>)|; and if there are each node in this list refers to an insertion number; for example, `\.{\\insert 250}' would correspond to a node whose |subtype| is |qi(250)| (the same as the |subtype| field of the relevant |ins_node|). These |subtype| -fields are in increasing order, and |subtype(page_ins_head)=65535, so +fields are in increasing order, and |subtype(page_ins_head)=65535|, so |page_ins_head| serves as a convenient sentinel at the end of the list. A record is present for each insertion number that appears in the current page. The first one was introduced by svn rev 2386 (luatex 0.41.0) and the first one dates back from at least 0.25.4. Manuel.
