Tomoko Uchida commented on LUCENE-8778:
---------------------------------------
bq. Now documented SPI names are camel cased, so it would be better that we
preserve original names as is.
In that case, for example "htmlStrip" and "htmlstrip" can be registered as
different services, of course this is problematic... :-/
I cannot come up with good ideas for now, should we go back to the lowercased
names (the same as the current SPI loader generates)?

> Each built-in analysis component (factory of tokenizer / char filter / token
> filter) has a SPI name but currently this is not documented anywhere.
> The goals of this issue:
> * Define SPI names as static final field for each analysis component so that
> users can get the component by name (via {{NAME}} static field.) This also
> provides compile time safety.
> * Officially document the SPI names in Javadocs.
> * Add proper source validation rules to ant {{validate-source-patterns}}
> target so that we can make sure that all analysis components have correct
> field definitions and documentation
> and,
> * Lookup SPI names on the new {{NAME}} fields. Instead deriving those from
> class names.
> (Just for quick reference) we now have:
> * *19* Tokenizers ({{TokenizerFactory.availableTokenizers()}})
> * *6* CharFilters ({{CharFilterFactory.availableCharFilters()}})
> * *118* TokenFilters ({{TokenFilterFactory.availableTokenFilters()}})
