TERMINOLOGY:
-- "slot" = A particular combination of tense/mood/person/number/etc.
Example slot names for verbs are "pres1p" (present indicative first-person plural), "impsub12s" (imperfect
subjunctive first/second-person singular form) and "pp" (past participle).
Each slot is filled with zero or more forms.
-- "form" = The conjugated Italian form representing the value of a given slot.
-- "lemma" = The dictionary form of a given Italian term. For Italian, always the infinitive.

RULES FOR CONJUGATION:
1. Present indicative:
-- Individual form overrides always take precedence.
-- Otherwise, if presrow: if given, this specifies all six forms (1s, 2s, 3s, 1p, 2p, 3p).
-- Otherwise:
1. The 1s form is generated from the explicitly specified pres1s principal part.
2. The 3p form is generated from the explicitly specified pres1s principal part by replacing -o with -ano (for -are verbs)
or with -ono (for -ere/-ire verbs).
3. The 2s and 3s forms are generated as follows:
a. If an explicit pres3s principal part is given using PRES1S^PRES3S, the 2s/3s stem is generated by removing final -a/-e.
b. Otherwise, if an explicit stem was given using stem:, this serves as the 2s/3s stem.
c. Otherwise, if the infinitive is root-stressed, the 2s/3s stem comes from the infinitive. This is used e.g.
with [[togliere]] (tòlgo, tògli, tòglie, togliàmo, togliéte, tòlgono), where the stem of the 1s and 3p forms
is different from the stem of the 2s and 3s forms.
d. Otherwise, the pres1s stem is used.
From this stem, the 2s form is generated by adding -i (possibly with some adjustments; two unstressed i's
together are compressed to one, and -h- is inserted after the stem if the verb is an -are verb and the stem ends
with -c or -g), and the 3s form is generated by adding -a (for -are verbs) or -e (for -ere/-ire verbs).
4. The 1p and 2p forms are generated from the infinitive stem (or explicit stem given by stem:) by adding -iàmo
(1p form) and -àte/-éte/-ìte (2p form, -are/-ere/-ire verbs). We don't use the pres1s form because it might have
a different stem (e.g. +isc verbs).
2. Present subjunctive:
-- Individual form overrides always take precedence.
-- Otherwise, if subrow: if given, this specifies all four forms (123s, 1p, 2p, 3p).
-- Otherwise:
1. If sub: is given, this specifies the 123s form; otherwise the 123s form is generated from the pres1s form by
changing -o to -a (for -ere/-ire verbs), or to -i (for -are verbs). E.g. for [[venire]], vèngo -> vènga;
for [[potere]], pòsso -> pòssa. sub: needs to be given for e.g. [[essere]] (pres1s sóno, sub1s sìa),
[[sapere]] (pres1s sò* but sub1s sàppia), [[fare]] (pres1s fàccio:fò*[archaic or dialectal] but sub1s just fàccia),
[[andare]] (similar to [[fare]]), [[dovere]].
2. The 3p form is generated from the 123s form by adding -no.
3. The 1p form is copied from the pres1p form.
4. The 2p form is generated from the 1p form by replacing -mo with -te.
3. Imperative:
-- Individual form overrides always take precedence.
-- Otherwise, if improw: if given, this specifies 2s, 2p.
-- Otherwise:
1. If imp: given, this specifies the 2s form; otherwise the 2s form is generated by copying the pres2s form
(for -ere/-ire verbs) or by copying the pres3s form (for -are verbs). We use the present indicative 2s/3s
forms to preserve vowel and other alternations in the root-stressed forms (for all -are verbs, for
[[venire]] and [[tenere]], for +isc verbs, etc.).
2. The 2p form is generated by copying the pres2p form.
3. The 3s, 1p, 3p forms are copied from the corresponding present subjunctive forms.

FIXME:
1. Fix inf_linked and lemma_linked to work like in [[Module:es-verb]]. (DONE)
2. Finish support for reflexive and pronominal verbs. (DONE)
3. Finish support for reflexive and pronominal imperatives. (DONE)
4. Finish support for negative imperatives. (DONE)
5. Fix handling of third-only verbs; require that irregular forms be specified in the first person.
Remove existing half-implemented support for specifying principal parts in the third person. (DONE)
6. Support defective verbs specified using e.g. redire<a/rièdo,-,redìto.imperf:-.fut:-.impsub:->.
Include categorization; but if row overrides or single overrides of all forms given, don't categorize
as defective for that row. (DONE)
7. Fix handling of aux; snarf code from [[Module:de-verb]] to handle aux with multiword expressions. (DONE)
8. Add automatic support for common irregular verbs: [[essere]], [[avere]], [[andare]], [[fare]], [[dare]],
[[dire]], [[venire]], [[vedere]], [[tenere]], [[bere]], etc. Should make combinations of these verbs
with clitics, and multiword expressions with these verbs, easier to handle. (DONE)
9. Add support for calling from {{it-verb}} in [[Module:it-headword]]. (DONE)
10. Throw an error if forms missing accents are specified (perhaps except with some special signal, to make
it easier to port the old [[Module:it-conj]]).
11. Consider adding combined clitic tables like in [[Module:es-verb]].
12. Consider adding automatic support for prefixed -fare verbs. (DONE)
13. Consider displaying irregular forms in a different color, as with the old [[Module:es-conj]], or adding
a triangle next to them, as with [[Module:ru-verb]].
14. Consider supporting replace_reflexive_indicators().
15. Add late (post-clitic-addition) overrides. (DONE)
16. PRES/PAST/PP spec should be required to come first to avoid ambiguities. (DONE)
17. Add variant codes to avoid mismatching variants in the conditional -èbbe/-ébbe, -éttero vs. érono, etc.
18. If explicit fut: given, it should control the conditional as well. (DONE)
19. If present -, sub:- or imp:-, it should suppress the whole row in the absence of row or individual overrides.
20. 'ci ci vuole' should maybe -> 'a noi ci vuole' instead of 'ci vuole'.
21. Instead of * before, use ! after so that * before can be used for reconstructed terms. (DONE)
22. When handling built-in verbs, automatically add + after vowel in cases like comporre. (DONE; HANDLED AUTOMATICALLY)
23. When handling built-in verbs, make sure we correctly handle root-stressed infinitives. (DONE)
24. When handling built-in verbs, make sure explicit ! afterwards is handled as if automatically there when a
prefix is added, and make sure final accent is handled correct when a prefix is added. In both cases, verify
both sfare and rifare, sdarsi and ridare. (DONE)
25. When handling built-in verbs, make sure we handle prefixes correctly w.r.t. negative imperatives. (DONE)
26. Support ref: in footnotes. (DONE)
27. Finish built-in -ire verbs.
28. Implement error("If past participle given as '-', auxiliary must be explicitly specified as '-'"). (DONE)
29. Make present participles default to enabled. (DONE)
30. Instead of a qualifier for syntactic gemination, use a superscripted symbol with a tooltip, as for {{it-IPA}}.
Do this automatically for multisyllabic terms ending in a stressed vowel, but don't do it if the verb ends up
non-final, as in [[andare a letto]].
31. [[darsi]]: imp2s is wrong; it generates [[datti|dàtti]] and also [[dàtti]] (which is wrong) (DONE)
32. [[liquefare]]: forms like liquefà missing the indication of following syntactic gemination; it should be automatic
in multisyllabic words.
33. [[ridare]] has ridò with a syntactic gemination footnote, but liquefà doesn't have it (see #32). It should be a
tooltip.
34. Add 'addnote[SLOT_SPEC]' to make [[tangere]] with disused 1s/2s/1p/2p easier to handle. (DONE)
35. Throw an error if comma seen in single form specs like 'imp:'. (DONE)
36. Overrides like phis:+[rare] of [[affarsi]] using built-in @ (from [[fare]]) don't properly pick up the irregular
built-in forms. (DONE)
37. Overrides like phis:afféci[rare] of [[affarsi]] using built-in @ (from [[fare]]) get the prefix duplicated. (DONE)
38. Support negated addnote like 'addnote[-pres3s][rare]'. (DONE)
39. Support comma-separated addnote spec for the equivalent of alternation. (DONE)
40. Issue an error if addnote spec has no effect. (DONE)
41. Support verbs in -gliela like [[fargliela]]. (DONE)
42. Support /\ notation for optional root-stressed infinitive with ending first, for [[suadere]] and derivatives. (DONE)
43. Support verbs in -gli like [[mancargli qualche rotella]]. (DONE)
44. Correctly incorporate links in multiword expressions from [[Module:it-headword]] so the autolinking algorithm there
works (e.g. for [[portare il cervello all'ammasso]]) and head=~... specs are correctly propagated. (DONE)
45. Support head= with the verb as part of a larger bracketed expression, e.g. for [[stare a vedere]],
{{it-verb|e/@|head=[[stare a]] [[vedere]]}}. (DONE)
46. Expand addnote[] notation to support references (maybe needs no work)?
47. Support verbs in -glire ([[boglire]], [[inorgoglire]], [[saglire]], etc.) correctly. (DONE)

--[=[
Data on how to conjugate individual rows (i.e. tense/aspect combinations, such as present indicative or
conditional).
The order listed here matters. It determines the order of generating row forms. The order must have
'inf' < 'pres' < 'sub' < 'imp' < 'negimp' because the present indicative uses the root_stressed_stem generated
by add_infinitive; the present subjunctive uses generated forms from the present indicative; the imperative uses
forms from the present subjunctive and present indicative; and the negative imperative uses forms from the infinitive
and the imperative. Similarly we must have 'fut' < 'cond' because the conditional uses the future principal part.
The following specs are allowed:
-- `desc` must be present and is an all-lowercase English description of the row. It is used in error messages and in
generating categories of the form 'Italian verbs with irregular ROW' and 'Italian verbs with missing ROW'.
-- `tag_suffix` must be present is a string containing the {{inflection of}} tags that are appended onto the
person/number tags to form the accelerator spec. For example, the spec "pres|sub" means that the accelerator spec
for the third singular present subjunctive will be "3|s|pres|sub". This accelerator spec is passed to
[[Module:inflection utilities]], which in turn passes it to [[Module:links]] when generating the link(s) for the
corresponding verb form(s). The spec ultimately gets processed by [[Module:accel]] to generate the definition line
for nonexistent verb forms. (FIXME: Accelerator support is currently disabled for forms with non-final accents.
We need to change the code in [[Module:inflection utilities]] so it sets the correct target not containing the
non-final accent.)
-- `persnums` must be present and specifies the possible person/number suffixes to add onto the row-level slot
(e.g. "phis" for the past historic) to form the individual person/number-specific slot (e.g. "phis2s" for the
second-person singular past historic).
-- `row_override_persnums`, if present, specifies the person/number suffixes that are specified by a row override.
If omitted, `persnums` is used.
-- `row_override_persnums_to_full_persnums`, if present, specifies a mapping from the person/number suffixes
specified by a row override to the person/number/suffixes used for conjugating the row. This is used, for example,
with the subjunctive and imperfect subjunctive, where the first element of the row override specifies
(respectively) the 123s and 12s forms, which need to be copied (respectively) to the 1s/2s/3s and 1s/3s forms.
If omitted, no such copying happens. It's still possible for the row override persnums to disagree with the
overall persnums. This happens, for example, with the imperative, where the 'improw:' row override spec specifies
only the 2s and 2p forms; the remaining forms (3s, 1p, 3p) are generated during conjugation by copying from other
forms, and can't be overridden using a row override. (They can still be overridden using a single override such
as 'imp3s:...' or a late single override such as 'imp3s!:...'.
-- `generate_default_principal_part`, if present, should be a function of two arguments, `base` and `do_err`, and
should return the principal part(s) for the row. The return value can be anything that is convertible to the
"general list form" of a slot's forms, i.e. it can return a string, an object
{form = FORM, footnotes = {FOOTNOTE, FOOTNOTE, ...}}, or a list of either. It must be present if `conjugate` is
a table, but may be missing if `conjugate` is a function, in which case the function needs to generate the
principal part itself or otherwise handle things differently. For example, the present indicative does not
specify a value for `generate_default_principal_part` because there are actually two principal parts for the
present tense (first and third singular), which are processed at the beginning of the present indicative
`conjugate` function. Similarly, the infinitive does not specify a value for `generate_default_principal_part`
because there is no principal part to speak of; the infinitive is generated directly from the lemma in combination
with the slash or backslash that follows the auxiliary and (in the case of a root-stressed infinitive) the
single-vowel spec following the backslash. If `do_err` is given to this function, the function may throw an error
if it can't generate the principal part; otherwise it should return nil.
-- `conjugate` is either a function to conjugate the row (of two arguments, `base` and `rowslot`), or a table
containing the endings to add onto the principal part to conjugate the row. In the latter case, there should be
the same number of elements in the table as there are elements in `row_override_persnums` (if given) or
`persnums` (otherwise).

-- `lemma` is the verb lemma, as specified by the user.
-- `verb` contains various properties of the verb derived from the lemma by analyze_verb().
-- `forms` contains the final per-slot forms. This is processed further in [[Module:inflection-utilities]].
-- This is a table indexed by slot (e.g. "pres1s"). Each value in the table is a list of items of the form
-- {form = FORM, footnotes = FOOTNOTES} where FORM is the actual generated form and FOOTNOTES is either nil
-- or a list of footnotes (which must be surrounded by brackets, e.g. "[archaic]").
-- `principal_part_specs` contains forms specified by the user in various fashions. The value is in the same form
-- as for `forms``, but the FORM contained in it is the actual user-specified form, which may be e.g. "#è"
-- rather than a verb form, and needs to be processed to generate the actual form. A spec may be "+" to insert
-- the default-generated form or forms, or "-" to indicate that this form doesn't exist. The source of these
-- forms is either
-- (a) prefixes 'imperf:', 'fut:', 'sub:', 'impsub:', 'imp:', etc. (the key is "imperf", "fut", etc.);
-- (b) specs in the format e.g. "vèngo:vègno[archaic or poetic]^viène,vénni,venùto" or "é:#è" (the key is one of
-- "pres", "pres3s", "phis" or "pp" as appropriate);
-- (c) an explicit stem specified using 'stem:' (the key is "explicit_stem_spec");
-- (d) a root-stressed infinitive spec such as "ó+" in "a\ó+\compóngo,compósi,compósto" (the key is
-- "root_stressed_inf"); this will have the value "+" (meaning to take the vowel spec from the present tense)
-- if a spec like "a\è" is given with only one backslash, and will be missing entirely if a spec like "a/è"
-- is given with a slash instead of a backslash;
-- (e) an auxiliary specified using e.g. "a[transitive]:e[intransitive]/è" (the key is "aux" and the value will
-- contain the actual auxiliary in the form in place of "a" or "e").
-- `principal_part_footnotes` contains per-row footnotes derived from overriding principal part specs of the form
-- '+[footnote]' used in conjunction with a built-in verb.
-- `principal_part_forms` contains the processed versions of the specs contained in `principal_part_specs`. The
-- keys are as in `principal_part_specs` and the values are the same as for `forms`.
-- `row_override_specs` contains user-specified forms for a full tense/aspect row using 'presrow:', 'subrow:', etc.
-- The key is "pres", "sub", etc. (i.e. minus the "row" suffix). The value is another table indexed by the
-- person/number suffix (e.g. "1s", "2s", etc. for "pres"; "123s", "1p", "2p", etc. for "sub"), whose values
-- are in the same format as `principal_part_specs`.
-- `single_override_specs` contains user-specified forms using 'pres1s:', 'sub3p:', etc. The key is the slot
-- ("pres1s", "sub3p", etc.) and the value is of the same format as `principal_part_specs`.
-- `late_single_override_specs` contains user-specified forms using 'pres1s!:', 'sub3p!:', etc., specifying late
-- overrides that take place after copying forms from one place to another and after adding reflexive clitics.
-- The key is the slot ("pres1s", "sub3p", etc.) and the value is of the same format as `principal_part_specs`.
-- `addnote_specs` contains specs specifying footnotes to add to individual slots or collections of slots using
-- 'addnote[SLOTSPEC,SLOTSPEC][FOOTNOTE][FOOTNOTE][...]'. Each element is an object of the form
-- {slotspec = {SLOTSPEC, ...}, footnotes = {FOOTNOTE, ...}}.
-- `is_irreg` is a table indexed by an individual form slot ("pres1s", "sub2s", "pp", etc.) whose value is true or
-- false indicating whether a given form is irregular. Currently, the values in `is_irreg` are used only by the
-- code in [[Module:it-headword]] to determine whether to show irregular principal parts.
-- `props` is a table of miscellaneous Boolean properties. Current properties:
-- - `impers` (impersonal verb, with only third-singular forms)
-- - `thirdonly` (third-person only verb)
-- - `nofinite` (verb is missing all finite forms)
-- - `no_root_stressed` (verb is missing all root-stressed forms)
-- - `presonly` (verb is missing all finite forms except the present indicative)
-- - `rre` (user specified the 'rre' indicator in conjunction with a syncopated reflexive verb like
-- [[contrarsi]] reflexive of [[contrarre]], which otherwise would get interpreted as the reflexive of
-- [[contrare]])
-- - `syncopated` (verb is syncopated, i.e. the infinitive ends in '-rre'; includes verbs with '-rre' infinitive
-- as well as reflexive verbs ending in '-orsi' or '-ursi' and verbs where the 'rre' indicator
-- was given by the user)
-- - `builtin` (verb uses a built-in conjugation in [[Module:it-verb/builtin]])
-- - `opt_root_stressed_inf` (verb used the \/ or /\ notation to indicate an optionally root-stressed infinitive;
-- to determine if a verb used the \ notation, look for a value in
-- base.principal_part_specs.root_stressed_inf)
-- `rowprops` is a table of tables of row-specific Boolean properties. Each subtable specifies a property of a
-- given row, such as whether the row is irregular. Specifically:
-- - `rowprops.irreg`: The row is irregular, i.e. at least one slot has an irregular form. Currently used to
-- determine whether to add categories like [[:Category:Italian verbs with irregular imperfect subjunctive]],
-- and whether to display the row's principal part in the headword line.
-- - `rowprops.defective`: The row is defective (missing one or more forms). Forms expected to be missing due to
-- 'impers' or 'thirdonly' don't count.
-- - `rowprops.all_defective`: The row is missing all forms. A row should be considered completely defective if
-- `rowprops.defective[row]` and `rowprops.all_defective[row]` (we need both checks in case of expected
-- missing rows, such as imperative with 'impers' or 'thirdonly').
-- - `rowprops.unknown`: The row has at least one unknown form.
-- - `rowprops.all_unknown`: All forms of the row are unknown.
--
-- There should be no other properties set directly at the `base` level.
