Seconding this recommendation for Emacs CPerl mode. The integration with "speedbar" makes navigating even complex hierarchies easy, with CPerl supplying tags for Perl files in the speedbar window. Emacs even has a Windows port, last I checked, so you can use it on almost any system.

Yes cperl's syntax parsing is great, I use it for auto-indentation and formatting, which happens far faster than shelling out to perltidy.

Though (tangential!) it's giving me a hardtime ATM, because I have y_max somewhere in my code/comments/pod and it thinks it's an unfinished tr with _ as delimiter.

update

Added (cperl-mode) to title and considered to reparent this sub-thread into an own one

EDIT: please own thread possible, quite a drift ?

> I have y_max somewhere in my code/comments/pod and it thinks it's an unfinished tr with _ as delimiter.

Confirmed, even this is wrong:

sub y_max {
    1
}

Send a patch or report to the maintainers.

Update: Done.

map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]

This particular bug should be already fixed in the Emacs repository, available as cperl-mode.el. However, it is only backported to Emacs versions 26.1 and above.

> unfinished tr with _ as delimiter.

actually it's definitely a bug in cperl's parser, the only way to have valid word characters as delimiers for quote-like operators is to prepend a whitespace

The cases where whitespace must be used are when the quoting character is a word character (meaning it matches /\w/):

q XfooX # Works: means the string 'foo'
qXfooX  # WRONG!
[download]

 
  DB<21> $_= "ab"x6

  DB<22> use strict; y _a_X_

  DB<23> p
XbXbXbXbXbXb
  DB<23>
[download]

Though I must say this is one of the features of Perl I wouldn't ever miss...

... can we please have a feature to switch that (and y ) off?

Pretty please!

> The integration with "speedbar"

I think you mean Cperl's support for Imenu which helps me - among other stuff - to jump-to-definition of subs under the cursor.

I'm not using Speedbar but ECB on top and both can use Imenu as backend to list all subs in an extra panel instead of a drop-down menu-list.

edit

at the time I was experimenting with Speedbar it insisted in opening an extra "docked" window instead of splitting the current one, which was really kind of annoying. I know it's better nowadays.

Yes, the support is for imenu. I highlighted speedbar because it has been mentioned in this thread.

The vanilla M-x speedbar still opens an extra window ("frame" in Emacs lingo), but MELPA offers sr-speedbar which uses the same frame. I haven't tried it myself, though.

I'm pretty sure I once installed it on Ubuntu.

It's also available for OS X. I've diddled minimally with it and it's got some neat features (works with remote files over ssh, embedded terminals, supposedly nice debug support if you've got an LSP backend (e.g. Perl::LanguageServer; although I've only minimally poked at that with lsp-mode and not used the debugger)).

It's not emacs though.

Only Emacs means Emacs! ;-)

Regarding LSP, the idea is that it's editor agnostic.

Unfortunately I don't have the resources to try all options out.

Would be nice to define some wanted criteria for an IDE and organize a demo "battle" ... :)
