Locale::Meta has been inspired by Locale::Wolowitz, and the base code,
documentation, and function has been taken from it. The main goal of
Lecale::Meta is to provide the same functionality as Locale::Wolowitz, but
removing the dependency of the file names as part of the definition of the
language, to manage a new json data structure for the .json files
definitions, and also, add a meta field in order to be able to extend the
use of the locate to other purposes, like search.
The objective of the package is to take different json structures,
transform the data into key/value structure and build a big repository
into memory to be use as base point to localize language definitions.
The metadata attribute "meta" defined on the json file is optional and is
used to maintain information related to the definition of the term.
package Locale::Meta;
new( [ $path / $filename, %options ] )
Creates a new instance of this module. A path to a directory in which JSON
localization files exist, or a path to a specific localization file. If
you pass a directory, all JSON localization files in it will be loaded and
merged. If you pass one file, only that file will be loaded.
Note that "Locale::Meta" will ignore dotfiles in the provided path (e.g.
hidden files, backups files, etc.).
A hash-ref of options can also be provided. The only option currently
supported is "utf8", which is on by default. If on, all JSON files are
assumed to be in UTF-8 character set and will be automatically decoded.
Provide a false value if your files are not UTF-8 encoded, for example:
Locale::Meta->new( '/path/to/files', { utf8 => 0 } );
Receives a path to a directory in which JSON localization files exist, or
a path to a specific localization file, and loads (and merges) the
localization data from the file(s). If localization data was already
loaded previously, the structure will be merged, with the new data taking
precedence.
You can call this method and load_structure() as much as you want, the
data from each call will be merged with existing data.
Receives a Hash variable representing the same structure as the synopsis, and
load the structure into the locales.
Returns the string $msg, translated to the requested language (if such a
translation exists, otherwise no traslation occurs). Any other parameters
passed to the method (@args) are injected to the placeholders in the
string (if present).
The following exceptions are thrown by this module:
"You must provide a path to localization directory."
This exception is thrown if you haven't provided the "new()"
subroutine a path to a localization file, or a directory of
localization files. Read the documentation for the "new()" subroutine
above.
"Can't open localization directory: %s" and "Can't close localization directory: %s"
This exception is thrown if Locale::Meta failed to open/close the
directory of the localization files. This will probably happen due to
permission problems. The error message should include the actual
reason for the failure.
"Path must be to a directory or a JSON file."
This exception is thrown if you passed a wrong value to the "new()"
subroutine as the path to the localization directory/file. Either the
path is wrong and thus does not exist, or the path does exist, but is
not a directory and not a file.
"Can't open localization file %s: %s" and "Can't close localization file %s: %s"
This exception is thrown if Locale::Wolowitz fails to open/close a
specific localization file. This will usually happen because of
permission problems. The error message will include both the name of
the file, and the actual reason for the failure.
"Locale::Meta" requires no configuration files or environment variables.
"Locale::Meta" depends on the following CPAN modules:
-
Carp
-
JSON::MaybeXS
"Locale::Meta" recommends Cpanel::JSON::XS or JSON::XS for faster parsing of JSON files.
