Sorry for being unclear. I meant the Edit command in acme that takes sam commands and apply them to the buffer.
Not at all, I haven't used acme/plan9 for too long!
I use perl do do something similar. I have a program 's' which basically sed using the slightly more flexible perl regexps.
I frequently use, e.g.
||s 's/hello/good bye/g;s/yes/no/i'
the double pipe is a modification I made that means pipe the whole buffer i.e. :, then |
the argument can include arbitrary perl code of course, it doesn't have to be a regexp, the code is executed once per line.
Why cannot Edit be written like this?
#!/usr/bin/perl -w my $reg=shift;
eval "
while (<>) { $reg;print;}
