Hi all,

I'm trying dmd-2.075.0-rc1 in one of my projects where I use 
`squeeze` and `removechars`. Both of them are flagged as obsolete 
and in the docs we are suggested to use functions from std.regex 
and/or std.algorithm.

Does any one kow a one-liner from std.regex or std.algorithm that 
can take the role of those deprecated functions?

Thank's

As Seb somewhat undiplomatically put, there are replacements 
listed in the changelog.

Use std.regex.replaceAll to replace std.string.removechars:

import std.string;
import std.regex;

// old
"abc".removechars("a-z");

// new
"abc".replaceAll(regex("[a-z]"), "");



Use std.algorithm.iteration.uniq to replace std.string.squeeze:

import std.algorithm;
import std.string;

// old
"hello".squeeze;

// new
"hello".uniq;



Though it would be nice to have these alternatives listed right 
there in the deprecation message.

Thanks Meta and Seb!

Yes, the replacement is there 8), but as the deprecation message 
told me "to go to the docs", I only had in mind the library 
manual pages and not the changelog.

I agree with you that, at least, they could also be listed next 
to `squeeze` and `removechars`.

Thanks for your help!

Sorry - it wasn't intended to be an offense or aggressive. I 
consider(ed) RTFM as common internet slang.

It is, but you have to be careful with it. It could be "Read the Friendly

of the person writing it, and it's not always clear which the writer means.
And it's used so frequently to indicate that someone should have known to
read the manual that I expect that a lot of folks are going to take it the
wrong way - especially if that's all you say. So, while it _can_ be used in
a friendly manner, it's an acronym that I'd avoid.
