Hello, may I ask if the primitives \partokenname, \partokencontext will be implemented into LuaTeX? They were implemented in pdftex and XeTeX into TeXlive sources. I would very much welcome their implementation in LuaTeX, I need then on OpTeX macros. Regards Petr Olsak ----------- texk/web2c/NEWS: - new primitives \partokenname and \partokencontext allow overriding the   name of the internally-emitted \par token at blank lines, the end of   vboxes, etc. ----------- \pdftexprimitive{\Syntax{\Tex{\partokenname} \Whatever{control-sequence}}} \bookmark{\tex{partokenname}} \TeX{} inserts the {\it par-token} at empty lines and at various more places into the input stream. Its meaning is {\it end-paragraph} by default and it can be changed (by \type{\def}, for example). Its name is \type{\par} by default and you can change its name by \type{\partokenname}\Something{control-sequence}. The name of the {\it par-token} is given \Something{control-sequence}. The setting performed by \type{\partokenname} is global. The no-\type{\long} macros throw the error ``runaway argument'' if {\it par-token} is scanned to its parameter regardless its name. The following example releases the name \type{\par} to the ``user name space'', i.e.\ users can define and use \type{\par} as they need without any influence to behavior of internal \TeX{} algorithms. \starttyping \catcode`\_=11 \let\_par=\par \partokenname\_par Hello world.\end \stoptyping The token with name \type{\_par} is auto-emitted at the empty line and before \type{\end} primitive in this example. The no-\type{\long} macros can read parameters with \type{\par} but \type{\_par} is prohibited. \pdftexprimitive{\Syntax{\Tex{\partokencontext} \Whatever{number}}} \bookmark{\tex{partokencontext}} The {\it par-token} (i.e.\ the token with the name \type{\par} or with the name given by \type{\partokenname}) is inserted into the input stream depending on the \type{\partokencontext} value. Its value can be: 0: {\it par-token} is inserted at empty lines (more exactly, when a token    category 5 is found in the state~$N$ of reading a line) and before    \type{\end}, \type{\vskip}, \type{\hrule}, \type{\unvbox}, and \type{\halign}    when \TeX{} is in horizontal mode and at various error recovery cases. 1: {\it par-token} is inserted as above and moreover at the end of    \type{\vbox}, \type{\vtop}, and \type{\vcenter} if \TeX{} is in horizontal mode. 2: {\it par-token} is inserted as above and moreover at the end of    \type{\insert}, \type{\vadjust}, \type{\output}, \type{\noalign},    and items of \type{\valign} if \TeX{} is in horizontal mode. Default is \type{\partokencontext=0}, i.e.\ the cases 1 and 2 are processed by direct call of {\it end-paragraph} routine without emitted {\it par-token}. This is classical \TeX{} behavior. If \type{\partokencontext=1} then \TeX\ inserts {\it par-token} in additional cases: when vertical boxes are completed but horizotal mode is not finished. The settings \type{\partokencontext=2} deactivates all cases where classical \TeX\ uses direct {\it end-paragraph} routine and {\it par-token} is inserted in such cases. The setting value to the register \type{\partokencontext} is local.
