Full Discussion: Kshrc custom prompt will not work
Top Forums UNIX for Beginners Questions & Answers Kshrc custom prompt will not work Post 303040380 by MadeInGermany on Monday 28th of October 2019 07:52:30 AM

In ksh93 you can have:
Code:
PS1=$(printf "${GREEN}%s${NORM}@%s:${GREEN}%s${NORM}:$ " '$USER' '$HOSTNAME' '$(_collapsed_pwd)')

The ${USER} ${HOSTNAME} and $(_collapsed_pwd) are in 'ticks' for late evaluation.
Most complicated is the late invocation of the function (I had ran some tests: it only works in ksh93 not ksh88).
BTW there is an echo too many, resulting in double evaluation. Should be
Code:
_collapsed_pwd() {
  pwd | perl -pe '
   BEGIN {
      binmode STDIN,  ":encoding(UTF-8)";
      binmode STDOUT, ":encoding(UTF-8)";
   }; s|^$ENV{HOME}|~|g; s|/([^/.])[^/]*(?=/)|/$1|g; s|/\.([^/])[^/]*(?=/)|/.$1|g
'
}

locale::codes::langext

Locale::Codes::LangExt(3)				User Contributed Perl Documentation				 Locale::Codes::LangExt(3)

NAME

       Locale::Codes::LangExt - standard codes for language extension identification

SYNOPSIS

	  use Locale::Codes::LangExt;

	  $lext = code2langext('acm');		       # $lext gets 'Mesopotamian Arabic'
	  $code = langext2code('Mesopotamian Arabic'); # $code gets 'acm'

	  @codes   = all_langext_codes();
	  @names   = all_langext_names();

DESCRIPTION

       The "Locale::Codes::LangExt" module provides access to standard codes used for identifying language extensions, such as those as defined in
       the IANA language registry.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default IANA language
       registry codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying language extensions. A code set may be specified using either a name, or
       a constant that is automatically exported by this module.

       For example, the two are equivalent:

	  $lext = code2langext('acm','alpha');
	  $lext = code2langext('acm',LOCALE_LANGEXT_ALPHA);

       The codesets currently supported are:

       alpha
	   This is the set of three-letter (lowercase) codes from the IANA language registry, such as 'acm' for Mesopotamian Arabic.

	   This is the default code set.

ROUTINES

       code2langext ( CODE [,CODESET] )
       langext2code ( NAME [,CODESET] )
       langext_code2code ( CODE ,CODESET ,CODESET2 )
       all_langext_codes ( [CODESET] )
       all_langext_names ( [CODESET] )
       Locale::Codes::LangExt::rename_langext  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Codes::LangExt::add_langext  ( CODE ,NAME [,CODESET] )
       Locale::Codes::LangExt::delete_langext  ( CODE [,CODESET] )
       Locale::Codes::LangExt::add_langext_alias  ( NAME ,NEW_NAME )
       Locale::Codes::LangExt::delete_langext_alias  ( NAME )
       Locale::Codes::LangExt::rename_langext_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangExt::add_langext_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangExt::delete_langext_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.
