refactor(api): unify per-variant single-value enums into shared union-level enums

Each sealed-interface union with N variants used to emit N typed-string enums, one per variant, each holding exactly one wire value. Codegen now detects this pattern and emits ONE unified enum at the union level, retyping every variant's discriminator field to point at it. Unified enums (11 unions, 44 constants total): - ChatMemberStatus (6) - MessageOriginType (4) - BackgroundFillType (3) - BackgroundTypeKind (4) - ChatBoostSourceKind (3) - OwnedGiftType (2) - PaidMediaType (4) - ReactionTypeKind (3) - RevenueWithdrawalStateKind (3) - StoryAreaTypeKind (5) - TransactionPartnerType (7) Naming-collision cases (union name already ends in a discriminator concept noun, so the natural concat would stutter): BackgroundType, ReactionType, StoryAreaType, ChatBoostSource, RevenueWithdrawalState. The unified name ends with 'Kind' instead. 44 obsolete per-variant single-value enum types removed (e.g. ChatMemberOwnerStatus, MessageOriginUserType). The variant struct types themselves (ChatMemberOwner etc.) are unchanged; only their per-variant single-value enum aliases go away. Auto-inject MarshalJSON (commit 370c9c0) is unaffected — variant wire values still come from the discriminator-extractor pass. Call-site cleanup: - dispatch/filters/chatmember/chatmember_test.go - api/marshaljson_variants_test.go New test: api/unifiedenum_test.go covers ChatMemberStatus and MessageOriginType: variant-field retype, direct comparison without conversion, marshal discriminator preservation, full round-trip, stutter-suffix Kind sanity check.

 ListenAndServe starts an HTTP server on addr and blocks until Stop is called \(which triggers Shutdown with the caller's context\) or the server returns an error other than http.ErrServerClosed. Callers must invoke Stop\(ctx\) to cleanly shut down the server; the ctx passed here is only used as the server's base context for incoming requests.

lukaszraczylo	5523ed2b06	refactor(api): unify per-variant single-value enums into shared union-level enums Each sealed-interface union with N variants used to emit N typed-string enums, one per variant, each holding exactly one wire value. Codegen now detects this pattern and emits ONE unified enum at the union level, retyping every variant's discriminator field to point at it. Unified enums (11 unions, 44 constants total): - ChatMemberStatus (6) - MessageOriginType (4) - BackgroundFillType (3) - BackgroundTypeKind (4) - ChatBoostSourceKind (3) - OwnedGiftType (2) - PaidMediaType (4) - ReactionTypeKind (3) - RevenueWithdrawalStateKind (3) - StoryAreaTypeKind (5) - TransactionPartnerType (7) Naming-collision cases (union name already ends in a discriminator concept noun, so the natural concat would stutter): BackgroundType, ReactionType, StoryAreaType, ChatBoostSource, RevenueWithdrawalState. The unified name ends with 'Kind' instead. 44 obsolete per-variant single-value enum types removed (e.g. ChatMemberOwnerStatus, MessageOriginUserType). The variant struct types themselves (ChatMemberOwner etc.) are unchanged; only their per-variant single-value enum aliases go away. Auto-inject MarshalJSON (commit `370c9c0`) is unaffected — variant wire values still come from the discriminator-extractor pass. Call-site cleanup: - dispatch/filters/chatmember/chatmember_test.go - api/marshaljson_variants_test.go New test: api/unifiedenum_test.go covers ChatMemberStatus and MessageOriginType: variant-field retype, direct comparison without conversion, marshal discriminator preservation, full round-trip, stutter-suffix Kind sanity check.	2026-05-09 20:26:08 +01:00
lukaszraczylo	6f9b29ea0c	fix(release): stop tagging bot-api version Debug log from run 25609309601 confirmed semver-generator picks the chronologically most-recent tag as the version base. Whenever the bot-api-vX.Y tag was created after the library tag (or recreated during a partially-failing release), semver-generator picked bot-api-v10.0 as the base, couldn't parse 'v10.0' as full SemVer (no patch number), and restarted numbering from v0.0.x. Per direct user instruction: drop the bot-api tag entirely. The Bot API version still appears in the library tag message and release notes. Also delete the existing bot-api-v10.0 tag from local + remote so the next release sees only v* tags.	2026-05-09 20:06:02 +01:00
lukaszraczylo	bd80af240d	chore(release): add tag-fetch step + debugmode to diagnose semver Add an explicit git fetch --tags --force origin before semver-generator runs, plus log visible tags. Enable semver-generator's debugmode so the failure mode is visible. Diagnostic only — once we understand why semver-generator computes v0.0.2 despite v0.1.2 being the latest tag, the debug step can be removed.	2026-05-09 20:02:10 +01:00
lukaszraczylo	af180b75c5	fix(release): tag bot-api marker before library version semver-generator picks the chronologically most-recent tag as the version base. The previous order tagged the lib version first, then bot-api-vX.Y, leaving the bot-api tag as the most recent. semver- generator then treated 'vX.Y' as the base, couldn't parse it as full SemVer (no patch number), and silently restarted numbering from v0.0.x — causing surprise version downgrades like v1.1.1 -> v0.0.4 and v0.1.1 -> v0.0.2. Tagging bot-api-vX.Y first and the library version last keeps the library tag as the chronologically last one, so subsequent runs see it as the version base and bump correctly.	2026-05-09 19:58:14 +01:00
lukaszraczylo	29bf575cfd	chore(release): bump to v0.1.2 Empty commit to advance the auto-release pipeline. Latest tag was v0.1.1; semver-generator with the patch-prefix in the subject computes the next version as v0.1.2.	2026-05-09 19:51:34 +01:00
lukaszraczylo	370c9c0802	refactor(api): auto-inject discriminator value via generated MarshalJSON Sealed-interface union variants now hardcode their wire discriminator inside a generated MarshalJSON method instead of forcing callers to set the field on every struct literal. Drops a class of silent-rejection bugs where a typo in the discriminator slipped past the type checker and through to Telegram, which then rejected the request with no Go-side signal. The discriminator field stays exported so incoming-message decoding, type switches and debugging still see it. MarshalJSON wraps via a function-local type alias and emits an outer field with the same json tag; encoding/json (and goccy/go-json) resolve the outer field as the shallower one and override whatever the caller wrote. 99 variants get MarshalJSON. 7 are skipped because their unions dispatch structurally rather than by a string field: Message and InaccessibleMessage (MaybeInaccessibleMessage, dispatched on date), and the InputMessageContent family (InputTextMessageContent, InputLocationMessageContent, InputVenueMessageContent, InputContactMessageContent, InputInvoiceMessageContent — Telegram identifies these by the presence of message_text / latitude / phone_number / title etc.). Discriminator extraction lives in the emitter (cmd/genapi/emitter.go). Resolution: knownDiscriminators reverse-lookup for the 13 auto-decode unions, then doc-string analysis ("must be X" / "always “X”") of the variant's first required string field for marker-only unions (BotCommandScope, InputMedia, InputPaidMedia, InputProfilePhoto, InputStoryContent, InputPollMedia, InputPollOptionMedia, InlineQueryResult, PassportElementError). Variants the emitter cannot resolve a discriminator for are skipped silently rather than emitting broken code. Internal call-site cleanups: 4 manual discriminator assignments removed (api/unionparam_test.go, dispatch/filters/message/message_test.go, examples/inline/main.go ×2). Regression tests added in api/marshaljson_variants_test.go covering type-keyed variants, source-keyed variants, the override-user-typo guarantee, round-trip preservation through UnmarshalChatMember, the no-discriminator InputMessageContent path, and ride-along of non-discriminator fields. regen-from-fixture is deterministic across two consecutive runs; go test -race / go vet / staticcheck all clean.	2026-05-09 19:27:33 +01:00
lukaszraczylo	6ab80c27e1	fix(api): emit bare interface for all sealed-interface unions Optional fields whose type was a sealed-interface union without an auto-decode discriminator (BotCommandScope, InputMedia, InputPaidMedia, InputProfilePhoto, InputStoryContent, InputMessageContent, InputPollMedia, InputPollOptionMedia, InlineQueryResult, PassportElementError) were emitted as <Union> — pointer to interface, which is a Go anti-pattern: interfaces are already nil-able, and callers were forced to take addresses of concrete variants. The codegen path goType() guarded against pointer-wrapping using knownDiscriminators (only 13 unions with auto-decode dispatch), missing the 10 marker-only sealed interfaces. New package var knownInterfaceTypes is built from buildUnionTypeSet at emitter construction and covers both kinds. goType() now consults that. Net effect: - api/methods.gen.go: 3 BotCommandScope and 2 InputPollMedia fields become bare interface - api/types.gen.go: 14 InputMessageContent and 1 *InputPollOptionMedia fields become bare interface Regression tests in api/unionparam_test.go cover both shapes: direct concrete-variant assignment, and nil omitempty on the bare interface field.	2026-05-09 19:06:59 +01:00
lukaszraczylo	13ea7097e1	fix(docs): pin gomarkdoc repository URL flags for deterministic output CI run 25607949051 failed on the codegen-clean diff check. gomarkdoc auto-detects the GitHub repository URL from local git config — locally on a full clone with origin set, it generates source-line links ([func Foo](https://github.com/.../blob/main/...#L4590)); on the CI runner's fresh checkout, the remote info isn't available the same way and gomarkdoc emits unlinked headings (## func Foo). The committed docs (with links) and CI-regenerated docs (without links) diverged, breaking the gate. Pin the URL, branch, and path explicitly via gomarkdoc flags so output is identical regardless of where it runs.	2026-05-09 19:04:23 +01:00
lukaszraczylo	f899cc2663	fix(api): generate CallRaw + per-element decode for []<union> returns GetChatAdministrators returns []ChatMember, where ChatMember is a sealed-interface union. The codegen template emitted the generic client.Call[..., []ChatMember] for it — encoding/json cannot unmarshal a slice of an interface (no discriminator-aware path), so every real response from Telegram failed at the parse step: telegram: parse: json: cannot unmarshal api.ChatMember into Go struct field Result[[]ChatMember].Result of type api.ChatMember Fix is in cmd/genapi/methods.tmpl: add a third branch alongside the existing single-union branch. When a method returns []<union>, emit CallRaw + json.Unmarshal into []json.RawMessage + per-element Unmarshal<Union>(e). Mirrors what GetChatMember (single-element) already does, applied uniformly so any future slice-of-union method Telegram introduces inherits the right shape. Survey of v1.1.1 across all 23 sealed-interface unions confirms GetChatAdministrators was the only broken site; the fix regenerates just that one method body. New regression tests in api/getchatadministrators_test.go cover the typical admin+owner response and the empty-array case.	2026-05-09 18:57:54 +01:00
