1. Don’t use * in your setups names because names starting with an asterisk are system modes.

2. To load the defaults settings you have to use \setups[*reset] which needs the asterisks because it’s a system mode.

3.The settings doesn’t help because in the lines environment each line is a separate paragraph which makes \widowpenalty useless here.

Thanks for your reply, Wolfgang. So, according to 3, there is no way to prevent widow or orphan lines in a line environment, isn't it? Many thanks for your help again, Pablo -- http://www.ousia.tk

Not with the current implementation of the environment because it doesn’t know how many lines are there. With a Lua based solution it would be simple to add a mechanism to prevent a page break at a certain region because the needed information are available.

yes, some of that is on the agenda (not to hard but as usual it take a bit of thinking / experimenting to get an interface) basically it's a variant of \setpenalties (the plural \widowpenalties etc)

\startluacode

userdata = userdata or { } userdata.linescontent = userdata.linescontent or { }

local linescontent = userdata.linescontent

function linescontent.process() local lines = string.splitlines(buffers.getcontent("linescontent")) context.begingroup() for i=1,#lines do local l = lines[i] context("%s",l) context.par() end context.endgroup() end

\stopluacode

\def\startlinescontent {\grabbufferdata[linescontent][startlinescontent][stoplinescontent]}

\def\stoplinescontent {\ctxlua{userdata.linescontent.process()}}

\starttext

\startlinescontent One Two Three Four Five Six \stoplinescontent

\stoptext

Is there no way to avoid orphans and widows in the lines environment?

It's a bit ugly, but if the poem consists of individual stanzas, you can put each stanza in an non-bordered frame.

e.g.: % Set up the lines environment to put the contained lines in a frame so they are kept together \setuplines[indenting={yes,small,even}, <-- whatever options you want before={\startframedtext[frame=off]}, after=\stopframedtext]

% Then wrap your stanzas in individual line environments \startlines A maiden fair was seated there, Her hair of fine-spun gold. Azure eyes so clear and bright, So wondrous to behold. \stoplines

A frame will never be split across pages.

BTW this "trick"is on the wiki on the "Verse" page.

You don’t need any tricks to prevent page breaks in a lines environment because \setuplines[option=packed] already does it. Wolfgang

Wolfgang

You still need to make each stanza an individual lines environment, don't you?

You can change the definition of the inbetween key (default: \blank) which is used when you add a blank line in the environment. With the preference keyword for \blank you can allow a page break. \setuplayout[lines=8] \starttext \showframe \startlines[option=packed,inbetween={\blank[preference,line]}] Line 1 Line 2 Line 3 Line 4 Line 5 Line 6 Line 7 Line 8 \stoplines \stoptext Wolfgang
