Hello All!

There is intresting macros in cont-new -- shortcuts. It works pretty well, but I have one question: how to undefine them back?

For example after command:

\defineshortcut [//] [] [style=\em]

...

I can get slash only by \textslash (which is expected) and it breaks things like:

\typefile {some/dir/file}

So how to revert to previous meaning of '/'? It is possible to do it only temporarily?

Explicit \start a /b/ c \stop style grouping is normally best, but a shortcut is just an active character with a closing defimiter, so this will work for you special case:

\catcode`\/=\other \typefile {some/dir/file} \catcode`\/=\active

Thanks Taco. I was experimenting with \bgroup \egroup and thinking about some more explicit and visible. BTW where is these \start \stop defined? -- Radhelorn

I've experimented with various macros to undefine/temporarily disable shortcuts and found that most convenient variant is to insert this catcode changing into \typefile command. Why not to do this for every command, that accepts path parameters? This slows process down too much? But this is just an afterthought. I think that \defineshortcut commands are most useful inside some environment (start/stop pair). So it is possible to have such environment that restores back all catcode changes (or other variable changes) made inside it (like local variables in some programming laguages)? This can have many other uses. -- Radhelorn

i have no idea why you use shortcuts (i implemented it as a gimmick -)

Well I was reading sources and stumbled over these commands. I am using shortcuts to typeset programming examples in non standard languages and pseudo-code.

grouping is doable with:

\starttext

\startsetups whatever \defineshortcut [b] [style=bold] \defineshortcut [e] [style=slanted] \stopsetups

\definestartstop[whatever][commands=\setups{whatever}]

\input tufte

oeps or

\startwhatever oeps or \stopwhatever

oeps or

\input tufte

\stoptext

Many thanks! I've looked this indeed! It is a pity that such useful command (setups) remains undocumented. As far as I understand inside setups can be any commands and environment changes are fully restored after their execution. Right? And \setups command can replace any single command (in arguments and such). If this is OK, then I will try to collect some more examples and post them on the WIKI later this week. -- Radhelorn
