# Interactively checking default hyphenations

I'm using this programme

\let\\\showhyphens
\documentclass{article}
\usepackage[british]{babel}
\begin{document}


to check default hyphenations interactively by typing

*\\{necessarily}


&c. Is there a way to do this without having to type \\{}?
(Something similar perhaps to expr.mf.)

(And what would be the most correct place to put this under the local ~/texmf/?)

You could set up the main vertical list to use the same settings as the box that \showhyphens uses but here I just loop and apply \\ each time, and empty entry returns you to the * prompt

\let\\\showhyphens
\documentclass{article}
\usepackage[british]{babel}
\begin{document}
\loop
\typein[\tmp]{Word:}
\\{\tmp}
\ifx\tmp\empty\else
\repeat

• +1, but maybe you could remove the \let\\\showhyphens, use \showhyphens directly and finish with \end{document} for good measure? Yes, I know, I am so conventional. :-) – frougon Aug 1 at 12:54
• @frougon I wondered about doing that (and putting \stop after the loop) but I decided to return to the * prompt so the \\  shorthand might still be needed if the OP thinks of another word to check. – David Carlisle Aug 1 at 13:09
• Ah, okay... thanks for the explanation, then. :-) – frougon Aug 1 at 13:30
