Hi Andreas, > There is a name clash between l3io and l3messages. l3io defines > a \iow_newline: (with colon), whereas l3messages requires a > \iow_newline (without colon). > > I am not sure if it should be a function or a variable. i think of it as a function though those things are a bit "matter of opinion". Basically variables (other than tlps) cannot be used in the input stream by themselves. tlps are different as they acknowlegde the fact that TeX operates on token streams and tlps are simply containers for parts of the stream but it is interesting to look at the history (opinions change over time) ... at one stage it was \c_iow_newline .. then .. \iow_newline: ... then ... > * Since \err_newline: is a function, \iow_newline: should be > a function, too. i think it should be \iow_newline: and the documentation and code updated cheers frank advance warning: I plan to clean up the names used for certain functions in l3iow as they are not really fully consistent (probably in 4 weeks) --- will send out proposal for changes then for those who are interested.
