[mc] User menu: pattern matching acts not as expected

[Eugen Fabian Karban via mc]

Hello 

 

I'm not really sure if it's mc problem.

Trying to match files with spaces in name. This fails with foreign chars...but strange...just in mc.

I'm using:

 

$ mc -V
GNU Midnight Commander 4.8.22
Kompiliert mit GLib 2.58.2

$ locale
LANG=de_DE.UTF-8
LANGUAGE=
LC_CTYPE="de_DE.UTF-8"
LC_NUMERIC="de_DE.UTF-8"
LC_TIME="de_DE.UTF-8"
LC_COLLATE="de_DE.UTF-8"
LC_MONETARY="de_DE.UTF-8"
LC_MESSAGES="de_DE.UTF-8"
LC_PAPER="de_DE.UTF-8"
LC_NAME="de_DE.UTF-8"
LC_ADDRESS="de_DE.UTF-8"
LC_TELEPHONE="de_DE.UTF-8"
LC_MEASUREMENT="de_DE.UTF-8"
LC_IDENTIFICATION="de_DE.UTF-8"
LC_ALL=

Here my mc user menu:
################################
shell_patterns=0

+? f [[:space:]] & t r
R Rename - Replace " " in Name
        rename 's/ /\./g' %f -v
################################

case 1:
filename='file_without_spaces'
debug=Falsch: f [[:space:]]
result=works as expected

 

case 2:
filename='file with spaces'
debug=Wahr: f [[:space:]]
result=works as expected

 

case 3:
filename='file_without_spaces_utf8_local_chars_ä_ü_ö_ß_'
debug=Falsch: f [[:space:]]
result=works as expected

 

case 4:
filename='file_without_spaces_utf8_nonlocal_chars_à_á_'
debug=Wahr: f [[:space:]]
result=works NOT as expected (WRONG)

 

On the otherside on the bash level everything works as expected:

 

$ var='file_without_spaces'
$ [[ $var =~ [[:space:]] ]] && echo "var has spaces" || echo "var has NO spaces"
var has NO spaces

 

$ var='file with spaces'
$ [[ $var =~ [[:space:]] ]] && echo "var has spaces" || echo "var has NO spaces"
var has spaces

 

$ var='file_without_spaces_utf8_local_chars_ä_ü_ö_ß_'
$ [[ $var =~ [[:space:]] ]] && echo "var has spaces" || echo "var has NO spaces"
var has NO spaces

 

$ var='file_without_spaces_utf8_nonlocal_chars_à_á_'
$ [[ $var =~ [[:space:]] ]] && echo "var has spaces" || echo "var has NO spaces"
var has NO spaces

 

Using the pattern "\s" as replacement for "[[:space:]]": the same problems.

Much more in mc user menu setting the match pattern as :

 

+? f à & t r

 

filename='file_without_spaces_utf8_nonlocal_chars_à_á_'
debug=Wahr: f à
result=works as expected

 

Any hint? Thank You in advance

Eugen
