Java Bash: Nested functions and including other scripts
Hello.

I have the following problem with bash code:

Code:
function fl1_load_modules_and_get_list()
...........
	for module in $FL_MODULES_TO_PROCESS
	do
		source "${FL_MODULE_DIR}/${module}/module.sh"
	done
...........
}

function fl1_handle_install
{
	local FL_MODULES_TO_INSTALL=$(fl1_load_modules_and_get_list $1)
	
	#Executing pre-install routines
	for module in $FL_MODULES_TO_INSTALL
	do
		$(fl_mod_${module}_pre_install)
	done
}

First function is called inside the second one. First function loads scripts in which functions with predefined names reside. The second function calls the first and then attempts to call functions with names, that must be loaded with first one.
Loading files with source seem to complete successfully because I have
Code:
set -o errexit
set -o nounset
set -o pipefail

at the main script.

But when $(fl_mod_${module}_pre_install) call is done, I can see a message like /usr/local/fractal/fl/lib/handle_install.sh: line 8: fl_mod_php_pre_install: command not found
Somehow functions loaded by the first function are not imported into the global scope... Any idea why?

Thanks.

locale::codes::langvar

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.
