# Metas To define a meta called `example_meta`, add the name as an entry point: ```ini [options.entry_points] plover.meta = example_meta = plover_my_plugin.meta:example ``` The meta can be used in dictionary entries: ```json { "S-": "{:example_meta:argument}", "T-": "{:example_meta}" } ``` Metas are implemented as **functions** that take a {class}`formatting._Context` and an optional string argument. If an argument is not passed in the dictionary entry, it will be `''`. The meta function returns a {class}`formatting._Action` which will then be applied to the existing output. You will want to use either {meth}`context.new_action()` or {meth}`context.copy_last_action()` as the basis for the output value. Previously translated text can also be accessed. ```python # plover_my_plugin/meta.py def example(ctx, argument): pass ``` % TODO: % - new actions (plover-current-time?) % - accessing/modifying previous actions (retro_currency) % - document context/actions API
