How to edit a velocimacro without restarting velocity?

I have been having the same issue with NVelocity (C# port of velocity). Digging through their souce I found that the re-loading of the macros in the global name space are controlled by the following property.

properties.SetProperty(RuntimeConstants.VM_PERM_ALLOW_INLINE_REPLACE_GLOBAL, true);

I havn't tested this with velocity but looking at their documentation the property exists and seem to do exactly what you need.

Looks like you cant do what you want. The only way I could get macro definitions to reload is to put them in their own library file and set the velocimacro.library.autoreload = true.

From http://velocity.apache.org/engine/devel/developer-guide.html

velocimacro.library = VM_global_library.vm

Multi-valued key. Will accept CSV for value. Filename(s) of Velocimacro library to be loaded when the Velocity Runtime engine starts. These Velocimacros are accessable to all templates. The file is assumed to be relative to the root of the file loader resource path.

velocimacro.library.autoreload = false

Controls Velocimacro library autoloading. When set to true the source Velocimacro library for an invoked Velocimacro will be checked for changes, and reloaded if necessary. This allows you to change and test Velocimacro libraries without having to restart your application or servlet container, just like you can with regular templates. This mode only works when caching is off in the resource loaders (e.g. file.resource.loader.cache = false ). This feature is intended for development, not for production.
