Hi
I have a case where I am grabbing patterns and subsequent lines using
sed -n -e '/regex/{$!N;p;}'
This returns just the regex line when it is the last line of my file.
Now I may have even number of lines in some cases (regex never at end) and odd in very rare cases.
If the line... (6 Replies)

Locale::Codes::LangVar(3pm) Perl Programmers Reference Guide Locale::Codes::LangVar(3pm)NAME
Locale::Codes::LangVar - standard codes for language variation identification
SYNOPSIS
use Locale::Codes::LangVar;
$lvar = code2langvar('acm'); # $lvar gets 'Mesopotamian Arabic'
$code = langvar2code('Mesopotamian Arabic'); # $code gets 'acm'
@codes = all_langvar_codes();
@names = all_langvar_names();
DESCRIPTION
The "Locale::Codes::LangVar" module provides access to standard codes used for identifying language variations, 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 variations. 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:
$lvar = code2langvar('en','alpha-2');
$lvar = code2langvar('en',LOCALE_CODE_ALPHA_2);
The codesets currently supported are:
alpha
This is the set of alphanumeric codes from the IANA language registry, such as 'arevela' for Eastern Armenian.
This code set is identified with the symbol "LOCALE_LANGVAR_ALPHA".
This is the default code set.
ROUTINES
code2langvar ( CODE [,CODESET] )
langvar2code ( NAME [,CODESET] )
langvar_code2code ( CODE ,CODESET ,CODESET2 )
all_langvar_codes ( [CODESET] )
all_langvar_names ( [CODESET] )
Locale::Codes::LangVar::rename_langvar ( CODE ,NEW_NAME [,CODESET] )
Locale::Codes::LangVar::add_langvar ( CODE ,NAME [,CODESET] )
Locale::Codes::LangVar::delete_langvar ( CODE [,CODESET] )
Locale::Codes::LangVar::add_langvar_alias ( NAME ,NEW_NAME )
Locale::Codes::LangVar::delete_langvar_alias ( NAME )
Locale::Codes::LangVar::rename_langvar_code ( CODE ,NEW_CODE [,CODESET] )
Locale::Codes::LangVar::add_langvar_code_alias ( CODE ,NEW_CODE [,CODESET] )
Locale::Codes::LangVar::delete_langvar_code_alias ( CODE [,CODESET] )
These routines are all documented in the Locale::Codes::API man page.
