[jira] Commented: (MATH-361) Localization and Error Handling

["Gilles (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MATH-361?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12877801#action_12877801 ] 

Gilles commented on MATH-361:
-----------------------------

Revision 953668 contains a stripped-down of CM with a working version of the source files modified according to the proposal.
The code is in the ["sandbox" area|http://svn.apache.org/viewvc/commons/sandbox/commons-math_l10n/trunk/] of the repository.
Since the part of the proposal concerning the possibility of having a run-time selection of the localization library did not elicit a strong interest, the version shown there is the "simplest" case, where the dependency on the (external) library "cal10n" is _not_ optional.

Please have a look.

Notes:
# I had to modify some files due to dependencies on files which I had removed.
# I had to comment out some statements (e.g. in test files that referenced "TestUtils" which I had removed).
# I modified the "pom.xml" file:
** to include the new dependency on the "cal10n" library
** so that the resources (localized messages text) are included in the JAR (but this has the side-effect of including the "templates" directory, contrary to what was done by default)
