nviperl - nvi with embedded perl
|
||
|
|
|
||
|
|
=head1 SYNOPSIS
|
||
|
|
|
||
|
|
:perl require 'wc.pl'
|
||
|
|
:perl wc
|
||
|
|
:,$perldo $_=reverse($_)
|
||
|
|
|
||
|
|
=head1 DESCRIPTION
|
||
|
|
|
||
|
|
nvi with embedded perl allows you to run perl commands from within nvi.
|
||
|
|
Two additional commands are made available when you enable the perl
|
||
|
|
interpreter:
|
||
|
|
|
||
|
|
=over 8
|
||
|
|
|
||
|
|
=item * perl cmd
|
||
|
|
|
||
|
|
The perl command passes the specified commands to the perl interpreter.
|
||
|
|
The C<$VI::ScreenId>, C<$VI::StartLine> and C<$VI::StopLine> are set.
|
||
|
|
To find out how to maniplulate the nvi screens, see L<VI>.
|
||
|
|
|
||
|
|
=item * perldo cmd
|
||
|
|
|
||
|
|
The perldo command runs the specified commands on each line of the range
|
||
|
|
(every line of the file if no range specified). Before running the
|
||
|
|
command the line is copied into $_. If the command returns a true value
|
||
|
|
the line is replaced by the new value of $_.
|
||
|
|
|
||
|
|
The perldo commando does B<not> set the C<VI> variables. (If you think
|
||
|
|
this is a bad idea, tell me.)
