next

See the current Perl documentation for next.

Here is our local, out-dated (pre-5.6) version:


next - iterate a block prematurely



next LABEL

next



The next command is like the continue statement in C; it starts the next iteration of the loop:

    LINE: while (<STDIN>) {
        next LINE if /^#/;      # discard comments
        #...
    }

Note that if there were a continue block on the above, it would get executed even on discarded lines. If the LABEL is omitted, the command refers to the innermost enclosing loop.

See also continue for an illustration of how last, next, and redo work.

[shmem]: some experience with vim?
[Lady_Aleena]: None
[shmem]: I don't know geany, and don't know whether it has support for ctags.
[Lady_Aleena]: ctags?
[shmem]: ctags is a program which (recursively) extracts the symbols from source and stores them in a one-file database. This allows you to query the locations where these symbols (e.g. a subroutine name) are used anywhere in the source code tree...
[shmem]: ...from inside the editor.
[shmem]: apt-get install exuberant-ctags
[Lady_Aleena]: I think I heard vim has a big learning curve.
[shmem]: then in the root of your source tree run: ctags -R
[shmem]: you get a file named tags where all symbols and the places where they are used are listed
