The purpose of the acceleration code is to auto-generate pages for non-lemma forms (inflections) of a given lemma.
The way it works is approximately as follows:
1. When you have the accelerator gadget in [[MediaWiki:Gadget-AcceleratedFormCreation.js]] enabled, and you click on a
green link, the JavaScript code gathers all the green links on the page that have the same language and pagename as
the clicked-on green link and sends them to the generate_JSON() function in this module, which is a thin wrapper
around the generate() function. Each individual green link maps to an "entry" and has associated accelerator
properties that were specified by the `accel` object passed into full_link() in [[Module:links]]. Note that there can
-- be multiple entries passed to a single generate() call for various reasons, e.g.:
(1) Inside of a single inflection table there is syncretism, with two different inflections having the same form;
e.g. the same Latin form ''bonī'' occurs in three different inflections of the lemma [[bonus]]: the masculine
genitive singular, neuter genitive singular and masculine nominative plural. Hence there will be three entries.
(2) Inside of a single inflection table there are inflections that are spelled differently but map to the same
pagename due to diacritic removal; e.g. Latin ''bona'' (occurring in five different inflections: the feminine
nominative and vocative singular and the neuter nominative, accusative and vocative plural) and Latin ''bonā''
(the feminine ablative singular) will be merged together into a single call to generate() with six entries.
(3) There are two or more inflection tables, partly or completely duplicative. E.g. if a given lemma has
Etymology 1 and Etymology 2 sections, and the inflection of each separate etymology is the same and associated
with its own table, then clicking on any green link will result in (at least) two entries.
2. The generate() function is invoked like a template call, meaning all its arguments come as strings and need to be
parsed. It does the following steps:
(1) Parse its arguments.
(2) Convert each set of per-entry parameters into a `params` object.
(3) For each `params` object, generate a default entry, then, if there is a language-specific accelerator submodule,
call that module to customize the entry.
(4) Merge duplicate entries. This not only looks for completely duplicated entries but tries to merge entries that
differ only in the definition. In general, this will result in multiple definition lines under a single entry,
but definition lines that consist of calls to {{infl of}} will be further merged. For example, for the
example above with ''bona'' and ''bonā'', the five inflections of ''bona'' will be merged into a single entry
with a single call to {{infl of}} that looks something like this:
# {{infl of|la|bonus||nom//voc|f|s|;|nom//acc//voc|n|p}}
In other words, not only are the inflections combined into a single call to {{infl of}}, but inflections
with partly shared tags are further merged.
(5) Generate the Pronunciation and Etymology sections that go at the top, above all the entries. This is done either
by calling custom generate functions in the language-specific accelerator submodule, or (if those aren't given)
by merging the individual pronunciation and etymology lines, removing duplicates. Note that the default entry
generated in step (3) has no pronunciation or etymology (which are generated only by a language-specific
submodule), so by default there will be no Pronunciation or Etymology section.
(6) Assemble the parts of each entry into a string and paste all the strings together, along with any combined
Pronunciation and Etymology sections, to form the text of the entire per-language L2 section. Note that if you
have enabled the OrangeLinks gadget, accelerator entries can be created on already-existing pages, as long as
there's no L2 section for the language of the entries.
