[ast-developers] New -T/-P option for AST wc(1) to count in terminal cells ? / was: Fwd: Does AST printf(1)'s field width in "%3.4Ls" count in terminal cells or number of characters ?

[Roland Mainz]

Hi!

----

As a small followup to the question I'd like to add a new option to
wc(1) which measures in terminal cells using |wcwidth()|. I have the
patch ready&&tested except one question:

... Glenn: What would be the preferred option - "-T" for "terminal
cells" or "-P" for "positions" (POSIX wcwidth manpage talks about
"number of column positions of a wide-character code") ?

Bye,
Roland

Hi!

----

Does AST printf(1)'s field width for "%Ls" count in terminal cells
(e.g. uses |wcwidth()|) or does it count in (multibyte-)charactes ?

What do typeset -L/-R use to measure/limit strings ?

Bye,
Roland
