.mo file support in CodeIgniter - stopz - 05-29-2021
I'm making Composer packages for CodeIgniter and next step is to translate them into few languages using .mo files.
Let me explain why .mo is important:
* Easier standard to work with across companies.
Approach i came up with is:
1. In router allow for CI {locale} definition.
2. In Config/App.php we set defaultLocale to 'en' but fill up supportedLocales with all .mo files that are present.
3. In Language/en/Sample.php whe have something like this:
PHP Code:
<?php
return [
'GreetingText' => gettext('This text is in English but as it is requested from gettext it should read the .mo file for correct language set by CodeIgniter Request Service.')
];
I looked up system/Language/Language.php:134 which is a fallback to English language
-when requested one is not found-
thus this greeting should get triggered from lang('Sample.GreetingText');
Question/Problem: I can't find if CodeIgniter does set up Environment for .mo files and if not or what-not then does anyone get the picture i'm trying to achieve and have any suggestions of what could i try?

This would never be put into the framework this is an addon to the application.

Alright i solved my issue. So what helped me alot was https://stackoverflow.com/questions/1949162/how-could-i-parse-gettext-mo-files-in-php4-without-relying-on-setlocale-locales this MoParser class.
I have set up a little helper that is linked to service which has a MoParser Factory attached (so to save memory).
Here's the helper:
PHP Code:
if (! function_exists('l'))
{
/**
* Returns language from .mo or default CodeIngiter lang.php file.
* @method l
* @param string $index CodeIgniter language_key.
* @return string Output text.
*/
function l(string $index):string
{
# Take codeigniter locale.
$ci_locale = service('language')->getLocale();
# Directory separator & Vendor.
$DS = DIRECTORY_SEPARATOR;
$VENDOR = 'vendor' . $DS . 'myname';
# Language containing folder.
$LANG = 'Language';
# Find .mo file with the name of '$ci_locale'
# in given directory.
# Request call body and path from debug backtrace.
$call_body = array_search(__FUNCTION__, array_column(debug_backtrace(), 'function'));
$call_path = debug_backtrace()[$call_body]['file'];
# Check vendor position in call_path.
$vendor_position = strpos(strtolower($call_path), $VENDOR);
# Check if call is going trough vendor path.
$language_path = ($vendor_position)
# Check vendor language path.
? substr($call_path, 0, $vendor_position + strlen($VENDOR)) . $DS . 'src' . $DS . $LANG
# Check application language path.
: $language_path = APPPATH . $LANG ;
# Proposed mo file.
$mo_file = $language_path . $DS . $ci_locale . '.mo';
# Original Codeigniter Language_value.
$language_value = lang($index);
# Check if .mo file exists.
if (file_exists($language_path)
&& is_dir($language_path)
&& file_exists($language_path . $DS . $ci_locale . '.mo')
) {
# Bind with language.
return service('lang')->mo($mo_file, $ci_locale)->take($language_value);
}
# No .mo? Pass CodeIgniter default.
return $language_value;
}
}
And this is the .mo file factory which is called by the helper to return translations.
PHP Code:
<?php
namespace MyName\MyPackage\Models;
use MyName\MyPackage\Libraries\MoParser;
class Mo extends MoParser
{
/**
* Loaded mo file.
*/
protected array $mo;
/**
* Mo factory construction by file and locale.
* @method __construct
* @param string $mo_file Complete path to file.
* @param string $locale language locale.
*/
public function __construct(public string $mo_file, public string $locale = 'en')
{
# Load mo file.
$this->mo = $this->loadTranslationData($mo_file, $locale);
}
/**
* Retrieves translation from MO or returns original.
* @method take
* @param string $language_value input search value.
* @return mixed translation or original.
*/
public function take(string $language_value):mixed
{
# Check locale.
if (array_key_exists($this->locale, $this->mo))
{
# Check Mo.
return (array_key_exists($language_value, $this->mo[$this->locale]))
# Return translation.
? $this->mo[$this->locale][$language_value]
# Return original.
: $language_value ;
}
}
}
Hope these snippets help anyone stuck with including .mo files!

And like I mentioned above an addon Library.
