Lot F du jalon v1.8.0.

L'arbre de règles était sain et son vocabulaire mince : quatorze prédicats, aucun sur l'historique d'écoute, sur les tags que portent les fichiers eux-mêmes, ni sur l'endroit où une piste se trouve sur le disque.

Dix prédicats de plus

  • play_count_min / play_count_max — comptés comme le reste de l'application les compte : une ligne play_event est une écoute, sans durée minimale, le même nombre que la page Statistiques affiche. play_count_max: 0 est la seule manière de dire jamais écouté.
  • played_in_last_days / added_in_last_days — des fenêtres, pas des dates. Un jeu de règles est stocké une fois et réévalué pendant des années : une date épinglée dérive vers un sens que son auteur n'a jamais écrit. « Pas écouté depuis » s'écrit avec un Not, qui prend aussi ce qui n'a jamais été écouté.
  • sample_rate_min / bit_depth_min — les deux moitiés de hi_res dites séparément ; c'est le OU de deux seuils fixes et il ne sait pas exprimer « 88,2 kHz mais 16 bits ».
  • disc_number_is, path_contains (les deux côtés ramenés à /, donc la même règle se lit pareil quel que soit le séparateur écrit par l'OS qui a scanné).
  • tag_present / tag_contains — sur les tags personnalisés que feat: choose, reorder and resize the columns in track lists #588 stocke déjà. L'éditeur propose les clés que la bibliothèque porte vraiment, avec le nombre de pistes qui les portent : le compte sépare le tag présent partout de celui présent sur trois fichiers, et un sélecteur prouve que la clé existe, là où une clé tapée qui ne correspond à rien est une règle qui ne rend aucune piste sans que rien ne l'explique.

Le compteur vivant

Il remplace le bouton « Aperçu » : anti-rebond de 350 ms, relancé à chaque modification, et il montre retenus / correspondants dès qu'une limite coupe le résultat — le nombre qu'une liste tronquée ne peut pas donner. count_custom_smart_playlist compte dans SQLite au lieu de trier et de rapatrier cinq mille identifiants qu'un nombre à l'écran jetterait. preview_custom_smart_playlist part avec lui : sa moitié « 200 premiers identifiants » n'a jamais eu d'appelant.

Une réponse lente à une règle déjà modifiée est jetée au lieu d'écraser la réponse à la règle affichée.

Points de départ, et les règles en clair

Six jeux de règles prêts, qui remplacent celles d'une playlist existante quand on les applique : repartir de quelque chose de connu est exactement ce qui répare un jeu de règles emmêlé, et rien n'est écrit avant Enregistrer.

Et les règles dites en français sous le titre d'une playlist intelligente, pour que la question qu'elle pose (« pourquoi cette piste ? ») ait une réponse sans ouvrir l'éditeur.

Deux pièges qui valaient la peine

Les colonnes nullables. Une borne écrite col >= ? vaut NULL pour une piste sans la valeur — et NOT (NULL) vaut NULL aussi : la piste sort de la règle et de sa négation, ce qui se lit comme une bibliothèque qui perd des pistes. Toutes les bornes portent maintenant leur garde explicite, y compris hi_res, qui ne l'avait pas et qui est le site jumeau des prédicats ajoutés ici. Un test tombe si on retire la garde.

Les métacaractères de LIKE. Un tiret bas n'a rien d'exotique dans un chemin ou un numéro de catalogue, et My_Music happait silencieusement MyXMusic. L'échappement est centralisé et appliqué aux cinq prédicats « contient », pas seulement aux deux que cette branche ajoute. Le COLLATE NOCASE que ces fragments portaient est parti : LIKE ignore les séquences de collation sous SQLite et est déjà insensible à la casse en ASCII — et placé après ESCAPE, il s'appliquait au caractère d'échappement, donc il affirmait sur le SQL quelque chose de faux.

Validation

  • Windows : fmt --check, clippy -D warnings à 0, typecheck, lint, prettier, 216 tests core.
  • Fedora : fmt, clippy 0, 614 app + 328 core (+9, tous nouveaux).
  • macOS non repassé : aucun code spécifique à une plateforme ne bouge.
  • 8 passes de revue CodeRabbit locales avant le push, ~25 retours distincts, deux écartés avec la raison (le tri sans limite ; un faux positif d'exports).

Closes #591.

…a rule summary

The rule tree was sound and its vocabulary thin: fourteen predicates,
none of them about listening history, the files' own tags, or where a
track sits on disk.

Ten new predicates. Play count and play window, both counted the way
Statistics counts them (one play_event row is one play), with
play_count_max: 0 as the only way to say "never played". Date added,
sample rate, bit depth, disc number and path as their own rules. And
the two that change what the feature can express: tag_present and
tag_contains, over the custom tags #588 already stores, offering the
keys the library actually holds with the number of tracks carrying
each.

The relative windows are windows, not dates: a rule set is stored once
and re-evaluated for years, and a pinned date drifts into meaning
something its author never wrote. The clock is a parameter of the
builder so the arithmetic is testable against a pinned instant.

Bounds on a nullable column carry an explicit NULL guard. Without it
the fragment is NULL for a track missing the value and NOT (NULL) is
NULL too, so the track falls out of the rule and out of its negation
both, which reads as the library losing tracks. Proved by a test that
fails when the guard is removed.

A live match count replaces the Preview button: debounced, re-run on
every edit, showing kept / total whenever a limit is cutting the
result, and dropping a slow answer to a rule the user has already
changed. count_custom_smart_playlist counts in SQLite rather than
sorting and shipping five thousand ids a number on screen would throw
away; preview_custom_smart_playlist is removed with it, its ids half
never having had a caller.

Six ready-made rule sets, which replace an existing playlist's rules
when applied: starting again from something known to work is what
repairs a tangled rule set, and nothing is written until Save.

And the rules said in words under a custom smart playlist's title, so
the question a smart playlist raises has an answer without opening the
editor.

Closes #591.
The one that mattered: a failed count called setCount(null), so the
footer showed "counting…" for good — nothing was counting any more.
The comment right above it promised the opposite, that the last good
number stays. It does now, and with no number at all the dash says
"unknown" rather than claiming work is happening.

LIKE metacharacters are now escaped, in one helper applied to all five
contains-predicates rather than only the two this branch adds: an
underscore is not an exotic character in a path or a catalogue number,
and "My_Music" quietly taking in "MyXMusic" is a wrong answer nothing
on screen explains. Escaping without the ESCAPE clause is worse than
not escaping, so the pattern and the clause are built by the same pair
of functions. Proved by a test on a real SQLite.

kHz written through Intl rather than toFixed, in both the summary and
the editor: 88.2 reached a French reader as "88.2" in a sentence where
every other number carried a comma.

The three value widgets this branch adds now name themselves, the way
the tag picker already did — the predicate select beside them carries
the meaning visually, and a screen reader reaching the second control
of the pair announced only its value. The label comes from the
predicate catalogue, the only list of that pairing.

The summary's effect keys on the playlist id and its rules instead of
the object, which the view rebuilds on every library change.

And Russian: after "не менее", 2-4 takes the genitive singular.
…s in nine languages

hi_res is two nullable bounds at once and had neither guard, so a file
with no sample rate and no bit depth recorded fell out of the rule and
out of its negation both — the same defect the new bounds were written
to avoid, one line above them. The positive answer does not move
(TRUE OR NULL was already TRUE); the negation now takes in the tracks
nobody could see. A test that fails without the guard.

Durations go through formatDuration, the m:ss every other duration in
the app uses. Rounding to whole minutes made the sentence claim a
bound the rule does not have: a rule of 90 seconds read as "≥ 2 min".

The two audio selects keep a value their list does not offer. A
controlled select with no matching option renders blank and rewrites
the rule on the next change, which is a stored rule silently edited by
opening it.

And the relative windows, which read as a starting point rather than a
window once the editor had composed label + number + unit: "Ajouté
depuis 30 jours" is not "added in the last 30 days", and Japanese,
Korean, Turkish and Hindi put the unit where the label had already
finished the sentence. Reworded in nine locales, with the singular
forms saying "the last day" rather than "the last 1 days". Indonesian
rating now uses the word the rest of that file uses.

Skipped: naming the sort when no limit is set. Without a limit the
sort decides the order of a list the reader is looking at, which the
list itself shows; with one it decides membership, which is the case
the sentence exists for. The reason is in the code.
…ero days

The tag picker matched case-insensitively but rendered the stored
spelling as the select's value: a rule naming Composer against a
library holding COMPOSER found no matching option and drew blank, as
if the rule named nothing. It now shows the canonical spelling while
the rule keeps its own, which the column's NOCASE collation resolves
either way.

A window field cleared to zero is not a wide rule or a narrow one, it
is a rule matching nothing — min on the input is a hint the keyboard
walks past. Normalised to one day.

And Hindi inflects its day: one दिन, several दिनों.
…without tags

The window field named itself and its siblings did not — the same
input element, one branch of the switch away. Every value widget in
the leaf now carries the predicate's own label, so a screen reader
reaching the second control of a pair announces what it is measuring
instead of only its number.

A library whose files carry no custom tag has nothing to put in a tag
rule, and the default key would be the empty string: a rule matching
nothing, saved without a word. The group is hidden until there are
keys, and comes back for a leaf that already is a tag rule — dropping
an option from a select under a value that uses it is what makes a
select render blank, which is the defect fixed one commit ago.
SQLite's LIKE ignores collating sequences and is already
case-insensitive across ASCII, so the COLLATE NOCASE these fragments
carried never decided anything. After the ESCAPE clause it is worse
than decorative: a trailing COLLATE binds to the escape character, not
to the comparison, so the SQL read as if a collation were at work on a
character that is never compared. Removed, with a test asserting that
a lower-case needle still finds an upper-case title — the behaviour
the clause looked like it was providing.

Skipped: interpolation placeholders said to diverge from en. Audited
every new key in all 17 locales; the only differences are singular
forms that drop {{count}}, deliberately, because "the last day" reads
better than "the last 1 day" and i18next does not require a
placeholder to be used.

…ith its rules

The summary was stamped with the playlist id alone, so saving an edit
or switching language left the old sentence on screen until the new
read landed — under the same id, describing rules the playlist no
longer has. The rules and the locale are part of the stamp now.

And the plural forms. CodeRabbit named French and Spanish; asking
Intl.PluralRules instead of guessing says the "many" category is real
in five of the seventeen — Italian, Portuguese and Brazilian
Portuguese too. Filled for all six counted keys, audited against Intl
rather than against a list I wrote.

Reachable only at counts near a million, so this is not a defect
anyone would have hit. It is fixed because the cost is a duplicated
string and the alternative is a key that silently answers in English —
the failure recorded when Russian and Arabic were missing categories
that fire at two.
