This module provides the implementation of {{ar-conj}} and {{ar-verb forms}} and is also called by {{ar-verb}} and {{ar-verb form}}.
The arguments are meant to be passed in through the parent frame, i.e. arguments specified to the template that invokes this module, rather than to the invocation itself.
The following external entry points are provided:
do_generate_forms: Meant for calling from other modules to generate the appropriate forms but not format them into a table. Used e.g. in Module:ar-headword and Module:ar-inflections.show: Implements{{ar-conj}}. The template (parent frame) arguments are documented thoroughly in{{ar-conj}}.verb_forms: Implements{{ar-verb forms}}.infer_radicals: Meant for calling from other modules to infer the appropriate radicals given an unvocalized pagename and the verb form.infer_radicals_json: Bot or test interface forinfer_radicals.infer_participle_vocalization: Meant for calling from other modules to infer the appropriate vocalization given an unvocalized active or passive participle, the verb form and occasionally other hints.infer_participle_vocalization_json: Bot or test interface forinfer_participle_vocalization.

This module implements {{ar-conj}} and provides the underlying conjugation functions for {{ar-verb}}
(whose actual formatting is done in [[Module:ar-headword]]).
Author: User:Benwing, from an early version (2013-2014) by User:Atitarev, User:ZxxZxxZ.

TERMINOLOGY:
-- "slot" = A particular combination of tense/mood/person/number/etc.
Example slot names for verbs are "past_1s" (past tense first-person singular), "juss_pass_3fp" (non-past jussive
passive third-person feminine plural) "ap" (active participle). Each slot is filled with zero or more forms.
-- "form" = The conjugated Arabic form representing the value of a given slot.
-- "lemma" = The dictionary form of a given Arabic term. For Arabic, normally the third person masculine singular past,
although other forms may be used if this form is missing (e.g. in passive-only verbs or verbs lacking the past).
]=]
--[=[
FIXME:
1. Finish unimplemented conjugation types. Only IX-final-weak left (extremely rare, possibly only one verb اِعْمَايَ
(according to Haywood and Nahmad p. 244, who are very specific about the irregular occurrence of alif + yā instead
of expected اِعْمَيَّ with doubled yā). Not in Hans Wehr. NOTE: Not true about this, cf. form IX اِرْعَوَى "to desist,
to repent, to see the light". Also note form XII اِخْضَوْضَرَ = form IX اِخْضَرَّ "to be or become green".
[DONE except for اِعْمَايَ]
2. Implement irregular verbs as special cases and recognize them, e.g.
-- laysa "to not be"; only exists in the past tense, no non-past, no imperative, no participles, no passive, no
verbal noun. Irregular alternation las-/lays-. [IMPLEMENTABLE USING OVERRIDES]
-- istaḥā yastaḥī "be ashamed of" -- this is complex according to Hans Wehr because there are two verbs, regular
istaḥyā yastaḥyī "to spare (someone)'s life" and irregular istaḥyā yastaḥyī "to be ashamed to face (someone)",
which is irregular because it has the alternate irregular form istaḥā yastaḥī which only applies to this meaning.
Currently we follow Haywood and Nahmad in saying that both varieties can be spelled istaḥyā/istaḥā/istaḥḥā, but we
should instead use a variant= param similar to حَيَّ to distinguish the two possibilities, and maybe not include
istaḥḥā.
-- ʿayya/ʿayiya yaʿayyu/yaʿyā "to not find the right way, be incapable of, stammer, falter, fall ill". This appears
to be a mixture of a geminate and final-weak verb. Unclear what the whole paradigm looks like. Do the
consonant-ending parts in the past follow the final-weak paradigm? Is it the same in the non-past? Or can you
conjugate the non-past fully as either geminate or final-weak?
-- اِنْمَحَى inmaḥā or يمَّحَى immaḥā "to be effaced, obliterated; to disappear, vanish" has irregular assimilation of inm-
to imm- as an alternative. inmalasa "to become smooth; to glide; to slip away; to escape" also has immalasa as an
alternative. The only other form VII verbs in Hans Wehr beginning with -m- are inmalaḵa "to be pulled out, torn
out, wrenched" and inmāʿa "to be melted, to melt, to dissolve", which are not listed with imm- alternatives, but
might have them; if so, we should handle this generally. [DONE]
-- يَرَعَ yaraʕa yariʕu "to be a coward, to be chickenhearted" as an alternative form of يَرِعَ yariʕa yayraʕu (as given in
Wehr). [IMPLEMENTABLE USING OVERRIDES]
3. Implement individual override parameters for each paradigm part. See Module:fro-verb for an example of how to do this
generally. Note that {{temp|ar-conj-I}} and other of the older templates already had such individual override params.
[DONE]
Irregular verbs already implemented:
-- [ḥayya/ḥayiya yaḥyā "live" -- behaves like a normal final-weak verb
(e.g. past first singular ḥayītu) except in the past-tense parts with
vowel-initial endings (all the third person except for the third feminine
plural). The normal singular and dual endings have -yiya- in them, which
compresses to -yya-, with the normal endings the less preferred ones.
In masculine third plural, expected ḥayū is replaced by ḥayyū by
analogy to the -yy- parts, and the regular form is not given as an
alternant in John Mace. Barron's 201 verbs appears to have the regular
ḥayū as the part, however. Note also that final -yā appears with tall
alif. This appears to be a spelling convention of Arabic, also applying
in ḥayyā (form II, "to keep (someone) alive") and 'aḥyā (form IV,
"to animate, revive, give birth to, give new life to").] -- implemented
