typikon/CHANGELOG.md

Changelog

Notable changes, in the terms docs/versioning.md sets out. Calendar entries change what a day reports, whatever the version number does.

1.1.2

Fixed

• The published description says what the package covers, and says the same thing in both registries. PyPI takes its summary from pyproject.toml, which 1.1.1 did not update, so it went out with the old one-line text while npm got the new one. The two READMEs had drifted apart as well: npm's opened without mentioning the Byzantine Catholic churches at all. All four now carry one sentence, and a test fails if any of them moves without the others.

1.1.1

Fixed

• The npm package's files are reachable through its exports map. A bundler asked for typikon/web/typikon_bg.wasm was told no such path is exported, so a web app that wants to hand the WebAssembly to init() as an asset had to reach around the package into node_modules. The documented call, await init() with no argument, was never affected.

Added

• tests/parity.sh: every binding asked the same twelve days and compared field by field against the command line. The days are the ones where the bindings could plausibly differ, and the surfaces are the command line, the Python wheel, Node by import and by require, TypeScript under --strict, a real browser, Deno, Bun, the C ABI and LuaJIT over it. A surface whose toolchain is absent is named as skipped rather than silently counted. --published runs the same checks against PyPI and npm instead of the checkout.

Changed

• The README no longer explains how the project tests or releases itself. That belongs to whoever works on it, and it is in docs/ where they will look; a reader who came to find out what a day of the Great Fast permits does not need it.
• A release runs what a push runs. The release workflow had been gated on cargo test alone, so the C ABI, the Lua binding, the Python parity check and the README examples were checked on the branch that led to a release but not on the release itself. A version cannot be reused on either registry, so the gate belongs before the upload.

1.1.0

New ways in, and no change to any day: nothing here moves a feast, a fast or a commemoration.

Added

• A C ABI, behind the capi feature, with a header in include/typikon.h. Dates cross it as Julian Day Numbers, so no struct layout is part of the contract. A day is opaque and owns its strings: an accessor returns the same borrowed pointer every time and allocates nothing, so reading one in a render loop is free. The accessors carry every field of the JSON, so a statusline does not need a parser. Errors go to a thread-local typikon_last_error().
• A LuaJIT FFI binding in examples/lua/typikon.lua, for AwesomeWM, WezTerm and Neovim, and a worked C example in examples/c/demo.c.
• jurisdictions::resolve_full, which resolves a jurisdiction together with the usage and the discipline. The Python bindings and the C ABI now share it rather than each keeping a copy, and it interns the combinations instead of leaking one per call.
• A JavaScript and TypeScript package, behind the wasm feature and published to npm as typikon. One WebAssembly build serves Node, Deno, Bun and the browser. A day comes back as a plain object rather than a handle: the same document --json emits, with nothing to free. The types are hand-written rather than inferred, and tsc --strict is a release gate the way mypy --strict already is. There is no remembered default jurisdiction there, because a browser has nowhere to keep one; the default is the New Calendar.

1.0.0

First stable release. The public surface is now the one described in docs/versioning.md, and breaking it requires a major version.

Calendar

Everything below changes what a day reports against pre-1.0 versions.

• A ranked saint now relaxes a weekday of a fast. A saint of vigil or polyeleos rank reaches wine and oil; a great feast reaches fish in the Nativity and Apostles' Fasts and wine and oil elsewhere. No saint of any rank brings fish into the Great Fast or the Dormition Fast. Days that had been reported stricter than any published calendar keeps them now are not, St Nicholas on a Wednesday of the Nativity Fast and the Forty Martyrs of Sebaste among them; on the new calendar it changes 104 days between 1 January 2020 and 31 December 2030.
• The Annunciation is tested before Great Friday and Great Saturday. In the years it falls on either it had been absorbed into them: reported as a total fast, demoted to a bullet, and its rank overwritten. It now lifts those days to wine and oil.
• Lazarus Saturday and Palm Sunday belong to the Great Fast season. They had belonged to none, so rules that key on the season fell through and the Byzantine Catholic jurisdictions reported no fast at all on Palm Sunday.
• The eves of the Nativity and Theophany relax to wine and oil when they fall on a Saturday or Sunday.
• Greek usage admits fish on any day of the Nativity Fast but Wednesday and Friday until 17 December. Slavic usage keeps fish to Saturdays and Sundays.
• The Protection of the Theotokos is a great feast in Slavic usage.
• The Nativity of the Forerunner is ranked a great feast.
• Melkite, Romanian Greek Catholic and Ukrainian Greek Catholic jurisdictions no longer report any day as binding. They had borrowed Ruthenian particular law, which is not their law.

Hardened

• The years this calendar answers for are 1 to 9999, enforced. Date::from_ymd and from_jdn reject anything outside them, arithmetic saturates rather than wrapping, and a seven-day walk stops at the boundary instead of running past it into dates whose ISO form was not ten characters long.
• --days is bounded at a hundred years and --indent at sixteen. Both took any integer and aborted the process on allocation.
• --update-menaion bounds the day it parses by the month it is in, and refuses to write when most of the year comes back empty. The page is fetched, so its contents are not this program's to trust: an unbounded parse wrote keys no lookup could match, and a page redesign would have blanked a year of commemorations in a calendar that had been working.
• today() says on stderr when it cannot read the local offset, rather than silently reporting UTC and so the wrong day either side of midnight.
• The Ukrainian Greek Catholic Church no longer loads the Ruthenian calendar of saints. It is Pittsburgh's, and lending it was the same error as lending the law.

Interfaces

• binds is null unless the day binds, rather than the string "none". Most jurisdictions legislate no binding fast at all, which is a different fact from a day that happens to oblige nothing.
• iCalendar UIDs carry the tradition and the discipline. Two feeds of the same day that say different things were sharing an identity, so a client treated them as one event.
• Date's Julian Day Number is behind jdn() and from_jdn() rather than a public field.
• fastLabel, emoji and reason are documented as presentation: the fields are stable, their wording is not.

Added

• Greek and Slavic usage as an explicit axis, per jurisdiction and overridable with --tradition.
• --typikon and --no-typikon: show a day at the Typikon's full discipline while still reporting what a church's own particular law obliges.
• --format csv and --format tsv, with --fields and --list-fields.
• --no-emoji.
• The rank marks the liturgical books print, as the sign field.
• ACROD, the American Carpatho-Russian Orthodox Diocese.
• --set-default remembers the tradition and the discipline alongside the jurisdiction.

Fixed

• The seven-day view no longer panics. It cut a title at a byte index into a string it had counted in characters, and every movable feast title carries an em dash, so at fourteen terminal widths, 80 among them, it aborted with exit 101. Every title the program can print is now cut at every width it can be asked to print at, in a test.
• The Python bindings honour TYPIKON_JURISDICTION. They read the config file where the command line reads the environment first, so the two answered for different churches on the same machine.

Packaging

• Requires Rust 1.85, which is what the dependency tree has needed since clap 4.6. rust-version had said 1.74, so the source distribution claimed to build on toolchains where cargo refuses outright.
• Classified as production/stable, with the Python version and platform classifiers PyPI indexes on, and Changelog, Documentation and Issues links.
• README links are absolute, because PyPI does not resolve relative ones and every one of them 404'd on the project page.

Changed

• Rewritten in Rust. It ships as one static binary with the menologion compiled in, and as an abi3 wheel. The port was verified by running it against the previous implementation over 199,446 day-records, 26 jurisdictions across 21 years, requiring every field of every record to match.
• iCalendar folds content lines on octets, which is what RFC 5545 counts. It had folded on characters, so a line with emoji ran up to 80 octets against a 75-octet limit.
• The seven-day view elides a long commemoration on a word boundary and takes its width from the terminal, rather than cutting at 44 characters mid-word.
• A malformed --date or an out-of-range --year is a usage error, not a traceback.
