Re: super search by regex (updated)

[LanX]

One of the problems with a regex interface is security.

You have to make sure it's not injecting code and that it's terminating in reasonable time.

Not sure why you need that tho

I used globs for that reason in one of my projects, (they translated to regex but safely) and it was sufficient for 99% of our users.

> not entirely clear to me what the separate strings with option does

I think you are talking about the option to separate different sub strings with something different than space, like that you can search for substrings where a space is included.

Like

• missing|your mother

would search

• "missing","your mother"

with "|" as separator, but

• "missing|your","mother"

by default

Update

Your way of linking is constantly logging me out, not everybody is using www.perlmonks.org.

Please prefer ids like [id://11160421] or node name links [node name]

site how to is not recommended for current advice. As it itself says:

This document is obsolete, and is maintained here only for archeological interest. Please read the current PerlMonks FAQ!

But really, for advice on how to link to nodes, best is the relevant FAQ: What shortcuts can I use for linking to other information? # All Links Within PerlMonks Should Be Relative.

It's listed below the textarea when replying

Want more info? How to link or How to display code and escape characters are good places to start.

Thanks! I will fix that.

Perl has special forces :

Perl maintains a cache of visited states in order to short circuit redundant paths through the NFA, permitting it to evaluate some searches in linear time that take polynomial or exponential time in other Spencer engines.

Ah, I see the separator is referring to your input.

"Please prefer ids like Re: super search by regex (updated) or node name links node name"

Great! I'll try to use that.
