TERMINOLOGY:

-- "slot" = A particular combination of tense/mood/person/number/etc. Example slot names for verbs are "pres_1s" (present indicative first-person singular), "pres_sub_2sv" (present	 subjunctive second-person singular voseo form) "impf_sub_ra_3p" (imperfect subjunctive -ra form third-person	 plural), "imp_1p_comb_lo" (imperative first-person plural combined with clitic lo). Each slot is filled with zero or more forms.

-- "form" = The conjugated Spanish form representing the value of a given slot.

-- "lemma" = The dictionary form of a given Spanish term. For Spanish, always the infinitive. ]=]

FIXME:

1. Implement no_pres_stressed for aterir, garantir. (NOTE: Per RAE, garantir used in all forms in Argentina/Uruguay.) [DONE] 2. Support concluyo. [DONE] 3. Fixes for veo -> ve vs. preveo -> prevé. [DONE] 4. Various more irregular verbs, e.g. predecir, redecir, bendecir, maldecir. [DONE] 5. Raising of e -> i, o -> u before -iendo, -ió, etc. occurs only in -ir verbs. [DONE] 6. Raising of e -> i, o -> u happens before subjunctive -amos, -áis in -ir verbs. [DONE] 7. Implement reflexive verbs. [DONE] 8. Implement categories. [DONE] 9. Implement show_forms. [DONE] 10. Reconcile stems.vowel_alt from irregular verbs with vowel_alt from indicators. May require moving the irregular-verb handling code in construct_stems into detect_indicator_spec. [DONE] 11. Implement make_table. [DONE] 12. Vowel alternation should show u-ue (jugar), i-ie (adquirir), e-í (reír) alternations specially. [DONE] 13. Handle linking of multiword forms as is done in Module:es-headword. [DONE] 14. Implement comparison against previous module. [DONE] 15. Implement categorization of irregularities for individual tenses. 16. Support nocomb=1. [DONE] 17. (Possibly) display irregular forms in a different color, as with the old module. 18. (Possibly) display a "rule" description indicating the types of alternations. 19. Implement replace_reflexive_indicators. 20. Implement verbs with attached clitics e.g. pasarlo, corrérsela. [DONE] 21. When footnote + tú/vos notation, add a space before tú/vos. 22. Fix erguir so ie-i vowel alternation produces ye- at beginning of word, similarly for errar. Also allow multiple vowel alternation specs in irregular verbs, for errar. Finally, ie should show as e-ye for errar and as e-ye-i for erguir. [DONE] 23. Figure out why red links in combined forms show up as black not red. 24. Consider including alternative superseded forms of verbs like ciar (e.g. pret_3s = cio, ció with footnote). 25. Allow conjugation of suffixes e.g. -ir, -ecer; need to fix in Module:inflection utilities. [DONE] 26. Allow specification of stems esp. so that footnotes can be hung off them; use + for the default. 27. Don't remove monosyllabic accents when conjugating suffixes. [DONE] 28. If multiword expression with no <>, add <> after first word, as with Module:es-headword. [DONE] 29. (Possibly) link the parts of a reflexive or cliticized infinitive, as done in Module:es-headword. [DONE] 30. Final fixes to allow Module:es-headword to use this module. [DONE] --]=]

Irregular conjugations.

Each entry is processed in turn and consists of an object with two fields: 1. match=: Specifies the irregular verbs that match this object. 2. forms=: Specifies the irregular stems and forms for these verbs.

The value of match= is either a string beginning with "^" (match only the specified verb), a string not beginning with "^" (match any verb ending in that string), or a function that is passed in the verb and should return the prefix of the verb if it matches, otherwise nil. The function match_against_verbs is provided to facilitate matching a set of verbs with a common ending and specific prefixes (e.g. andar and desandar but not mandar, etc.).

The value of forms= is a table specifying stems and individual override forms. Each key of the table names either a stem (e.g. `pres_stressed`), a stem property (e.g. `vowel_alt`) or an individual override form (e.g. `pres_1s`). Each value of a stem can either be a string (a single stem), a list of strings, or a list of objects of the form {form = STEM, footnotes = {FOONOTES}}. Each value of an individual override should be of exactly the same form except that the strings specify full forms rather than stems. The values of a stem property depend on the specific property but are generally strings or booleans.

In order to understand how the stem specifications work, it's important to understand the phonetic modifications done by combine_stem_ending. In general, the complexities of predictable stem and ending modifications are all handled in this function. In particular:

1. Spelling-based modifications (c/z, g/gu, gu/gü, g/j) occur automatically as appropriate for the ending. 2. Raising of e -> i, o -> u in -ir verbs before an ending beginning with i + vowel, as well as in the 1p/2p forms of  the present subjunctive (dormir -> durmiendo, durmió, durmamos), are handled here. Raising happens only for -ir verbs and only when the stem setting `raising_conj` is true (which is normally set to true when vowel alternations  `ie-i`, `ye-i`, `ue-u`, `i`, `í` or `ú` are specified). 3. Numerous modifications are automatically made before an ending beginning with i + vowel. These include: a. final -i of stem absorbed: sonreír -> sonrió, sonriera, sonriendo; b. in the preterite of irregular verbs (likewise for other tenses derived from the preterite stem, i.e. imperfect     and and future subjunctive), initial i absorbed after j and u (dijeron not #dijieron, likewise for condujeron,	  trajeron; also fueron not #fuyeron). This happens only when stem setting `pret_conj` == "irreg"; this must be set explicitly by irregular verbs. Does not apply everywhere because of cases like regular tejer (tejieron not	 #tejeron), regular concluir (concluyeron not #conclueron). c. initial i of ending -> y after vowel and word-initially: poseer -> poseyó, poseyera, poseyendo; ir -> yendo; d. initial i of ending -> y after gü, which becomes gu: argüir -> arguyó, arguyera, arguyendo; e. initial i of ending absorbed after ñ, ll, y: tañer -> tañó, tañera, tañendo; bullir -> bulló, bullera, bullendo 4. If the ending begins with (h)i, it gets an accent after a/e/i/o to prevent the two merging into a diphthong: caer -> caíste, caímos; reír -> reíste, reímos (pres and pret). This does not apply after u, e.g.  concluir -> concluiste, concluimos. 5. In -uir verbs (i.e. -ir verbs with stem ending in -u), a y is added before endings beginning with a/e/o: concluir -> concluyo, concluyen, concluya, concluyamos. Note that preterite concluyó, gerund concluyendo, etc. are handled by a different rule above (3b).

The following stems are recognized:

-- pres_unstressed: The present indicative unstressed stem (2s voseo, 1p, 2p). Also controls the imperative 2p and gerund. Defaults to the infinitive stem. -- pres_stressed: The present indicative stressed stem (1s, 2s, 3s, 3p). Also controls the imperative 2s. Default is empty if indicator `no_pres_stressed`, else a vowel alternation if such an indicator is given (e.g. `ue`, `ì`), else the infinitive stem. -- pres1_and_sub: Overriding stem for 1s present indicative and the entire subjunctive. Only set by irregular verbs and by the indicator `no_pres_stressed` (since verbs of this sort, e.g. aterir, are missing the entire	 subjunctive as well as the forms with stressed root). Used by many irregular verbs, e.g. caer, roer, salir, tener, valer, venir, etc. Some verbs set this and then supply an override for the pres_1sg if it's irregular, e.g. saber, with irregular subjunctive stem "sep-" and special 1s present indicative "sé*" (the * indicates that the monosyllabic accent should not be removed). -- pres1: Special stem for 1s present indicative. Normally, do not set this explicitly. If you need to specify an    irregular 1s present indicative, use the form override pres_1s= to specify the entire form. Defaults to pres1_and_sub if given, else pres_stressed. -- pres_sub_unstressed: The present subjunctive unstressed stem (1p, 2p, also 2s voseo for -ar verbs). Defaults to    pres1_and_sub if given, else the infinitive stem. -- pres_sub_stressed: The present subjunctive stressed stem (1s, 2s, 3s, 1p, also 2s voseo for -er/-ir verbs). Defaults to pres1. -- impf: The imperfect stem. Defaults to the infinitive stem. -- pret: The preterite stem. Defaults to the infinitive stem. -- pret_conj: Determines the set of endings used in the preterite. Should be one of "ar", "er", "ir" or "irreg". Defaults to the conjugation as determined from the infinitive. -- fut: The future stem. Defaults to the infinitive stem. -- cond: The conditional stem.
