tiny suckless C daily readings, floppy sized, bring your own Bible https://git.labunix.xyz/clectio.git/atom?h=main 2026-08-18T16:09:26Z 2026-08-18T16:09:26Z Lukasz Kasprzak lukas@labunix.xyz 2026-08-18T16:09:26Z urn:sha1:35ba4dc3dc5c85ddd4ccb3ec02f8fa5e1c11874b gen/liturgy_ef.h was regenerated in an earlier session without refreshing gen/verses_ef.keys.gz, which is what the Makefile actually packs the text from. The tables indexed 3584 verses; the packed text held 3248. print_day then read verse[i] past the end and dereferenced NULL. Reproduced against the fully committed tree with a plain make: 1246 of 10957 EF dates exit 139. Heavily clustered in Advent and December -- 30 of 30 years for each of 11-30, 12-03, 12-05, 12-06, 12-09, 12-10, 12-12, 12-21 through 12-25. OF swept clean, 0 of 10957. Three changes: - gen/ regenerated against lectio HEAD with keys and tables in step (3584 both), and text_ef.lz repacked from the same keys. - clectio.c records how many verses the packed text holds and prints "[verse text missing]" rather than reading past it. Missing text is a visible gap now, never a crash. Proved by rebuilding against the stale keys: 1246 crashes -> 0, placeholder shown. - upstream, lectio's clectio-gen now writes the .gz alongside the plain keys, so the two cannot drift again. The regenerated tables also carry two EF calendar corrections colitur argued from the 1962 Missal and lectio adopted: the Holy Family propers' 13-January omission of the Baptism, and RG 96(a)/97/98 transfers, which put St Joseph back on 2035-04-03 and 2046-04-03 (he was observed on no day of those years). Distinct days 656 -> 642: the ferias between Epiphany and the Sunday after it now repeat Epiphany's own Mass instead of each carrying a distinct one. Swept after the fix: EF 0 crashes, OF 0 crashes. Readings compared against lectio across 2030/2035/2046 (1095 days): no divergence beyond each project's own book abbreviations. 2026-08-18T14:55:23Z Lukasz Kasprzak lukas@labunix.xyz 2026-08-18T14:55:23Z urn:sha1:0bef4a169f5f8181926ff77e3429da8f4eda106b Holy Week had been reading Passion week's Masses, because lectio numbered both Passiontide weeks 0 and their days collided on the slug. Corpus Christi and the Sacred Heart -- two I-class feasts -- had no lectionary entry and were reading the Sunday before them through the walk-back. So were the ferias of the first weeks after Epiphany and after Pentecost, which have proper Masses under RG 299. Thirteen entries and one week-numbering fix upstream; regenerated against lectio 74d5575. Distinct days 644 -> 656. 2026-08-18T14:42:12Z Lukasz Kasprzak lukas@labunix.xyz 2026-08-18T14:42:12Z urn:sha1:293d9291a47f9b1f328a8acc99bf0f2a88edd02c Four upstream corrections land here at once: RG 87 Rogation Monday and Tuesday, violet, which lectio did not build Missal the weekdays within the Octave of the Nativity get their own Mass ("Diebus infra octavam", Titus 3:4-7 / Luke 2:15-20) instead of the Sunday's RG 78 the votive Office of Our Lady on Saturday, and RG 309(a)'s Mass for it RG 72 weeks after Epiphany counted from the first Sunday, not from 6 January Distinct days 657 -> 644. Verified from a genuine EF build across 730 days (2026-2027): ZERO colour mismatches against colitur. Every day of both years now agrees. 2026-08-18T14:09:03Z Lukasz Kasprzak lukas@labunix.xyz 2026-08-18T14:09:03Z urn:sha1:2b71b638eca7ec924166b64f31585af8399a753f Christmas Time runs to 13 January inclusive, so 6-13 January is white, not green. Eight days a year. Regenerated against lectio 27acee1. Verified from a genuine EF build: 7, 11 and 13 January 2026 all read white, and 14 January -- the first day that is really Time after Epiphany -- is unaffected. The day NAMES are deliberately unchanged ("1st Sunday after Epiphany" still), because lectio now separates the liturgical season from the season that names things; only the colour moved. 2026-08-18T13:43:09Z Lukasz Kasprzak lukas@labunix.xyz 2026-08-18T13:43:09Z urn:sha1:a4e63f408f9fb22f9a4a458b6d97bebe9b8be747 Twelve sanctoral colours corrected upstream: RG 124 gives red to Apostles, Evangelists and Martyrs, and missalemeum had ten confessors and virgins in red with two actual martyrs in white -- the rule applied backwards in both directions. Regenerated against lectio 967e911. Verified by a 730-day sweep (2026-2027) of this binary's output against colitur, built properly as EF via config.h rather than the make FORM= variable that does not do what it looks like. 29 colour differences remain and every one is a cited class: 16 C17 the BVM Saturday Office (RG 78), which lectio does not build 12 C1 the 6-13 January Christmastide boundary (RG 72-73) 1 C8 Rogation Monday 2027-05-03, violet under RG 128(d) for the Litanies' procession and Mass; lectio has no Rogation concept at all, so this is an absent feature rather than a wrong value Nothing unexplained. All three are feature gaps in lectio rather than errors in it, each already adjudicated verdict-colitur in that project's own divergence list. 2026-08-18T13:27:06Z Lukasz Kasprzak lukas@labunix.xyz 2026-08-18T13:27:06Z urn:sha1:fb967dccb95ff75c6a5f7a99f5e063effac8a94d The previous regeneration predated lectio's Good Friday fix (RG 128(b) + RG 132), so this table still coloured the day violet. Regenerated against lectio 4b2e1a1. Distinct days 656 -> 657: black is a new colour in this table, which had none before. Verified this time by building the EF binary properly and reading its output, not by decoding the table. The earlier commit could not check the vigil colours because `make FORM=ef` does not do what it appears to -- FORM is DERIVED from config.h, so that build used EF tables while compiling with FORM_OF defined, and the binary self-reported "Ordinary Form". Setting FORM_EF in config.h gives a genuine EF build. Cross-checked date by date against colitur, the source of these corrections: all ten corrected days now agree on colour, Good Friday included. A full 365-day sweep of 2026 leaves 23 colour differences, every one a known cited class -- 10 the BVM Saturday Office (colitur C17, RG 78, which lectio does not build), 6 the 6-13 January Christmastide boundary (C1, RG 72-73), and 7 the RG 124 red-colour class (colitur M21, verdict colitur, adjudicated against the scans) which lectio has not yet adopted. Nothing unexplained. 2026-08-18T13:03:17Z Lukasz Kasprzak lukas@labunix.xyz 2026-08-18T13:03:17Z urn:sha1:63a8eae8696c555e7bfa202c63e55d5fe5eb5a12 gen/liturgy_ef.h is generated by lectio's clectio-gen, so it inherited the EF calendar errors colitur found and lectio has now fixed: ubaldus and didacus ranked as commemorations rather than III-class feasts, and both August vigils coloured from missalemeum rather than from RG 128. Regenerated with `go run ./cmd/clectio-gen old 2025 2054`, against lectio at 46653b2. Distinct days 661 -> 656. Verified: "St. Ubaldus" and "St. Didacus" are now in the name table and were absent before, so the two rank corrections are present and both saints now displace the ferias that previously held those days. NOT independently verified here: the vigil COLOURS. The days[] table is a deduplicated 656-entry set indexed from elsewhere, and decoding that encoding to read a colour back would be guesswork rather than a check. Those values come from lectio, where they are pinned by TestTridentineMissalOverrides and were mutation-tested. Saying so rather than implying a check that was not run. 2026-08-17T08:51:43Z Lukasz Kasprzak lukas@labunix.xyz 2026-08-17T08:51:43Z urn:sha1:a0b61ff280bd368dd5aa5e1add0a78d4cf97e9ef Picks up the Lenten Ember fix: three lectionary sections were keyed ef-lent-1-{wednesday,friday,saturday} while lectio's calendar computes ef-lent-ember-{wed,fri,sat}, so the lookup missed them and every Lenten Ember day served Lent I Sunday's Mass. 84 of the 10 957 days in the compiled 2025-2054 range change, all of them Lent Ember days, all now carrying their proper Masses: Ember Wed 1 Kgs 19:3-8 / Matt 12:38-50 (was 2 Cor 6:1-10 / Matt 4:1-11) Ember Fri Ezech 18:20-28 / John 5:1-15 (same) Ember Sat 1 Thess 5:14-23 / Matt 17:1-9 (same) 84 rather than 90 because six Ember days across the range are displaced by a feast that outranks the feria and so were never affected: St Matthias (2029, 2040, 2051), the Chair of St Peter (2040, 2051) and St Joseph (2038). Verified by building an EF binary from the tables before and after and diffing all 10 957 days; no unclassified difference remains. The OF table regenerates byte-identical and is untouched. 2026-08-14T11:52:45Z Lukasz Kasprzak lukas@labunix.xyz 2026-08-14T11:52:45Z urn:sha1:c21f54526490eda1c05995659edd7b9b4c8c643d Picks up the seven EF calendar defects fixed in lectio this week. The OF table regenerates byte-identical and is untouched. 209 of the 10,957 days in the compiled 2025-2054 range change, every one of them traceable to a cited fix: 88 colour only 30 Holy Thursday violet -> white 30 3rd Sunday of Advent violet -> rose (Gaudete) 28 4th Sunday of Lent violet -> rose (Laetare; the other two years change name too, see below) 121 a different day observed 84 the Lent Ember days, previously emitted as plain ferias 20 St Matthew (21 Sep) and St Thomas (21 Dec) now winning over a coinciding Ember day -- a II-class privileged feria yields to a feast 4 13 January, the Commemoration of the Baptism of the Lord, taking an occurring Sunday's place as a feast of the Lord 3 St Joseph (19 Mar) now correctly transferred off a Sunday of Lent instead of displacing it 10 the 6 March - 5 April cluster of III-class feasts that the sanctoral generator had demoted to bare commemorations (Felicitas & Perpetua, John of God, Frances of Rome, Isidore of Seville, Vincent Ferrer) Verified by building an EF binary from the tables before and after and diffing all 10,957 days; no unclassified difference remains. 2026-07-28T20:51:40Z Lukasz Kasprzak lukas@labunix.xyz 2026-07-28T20:51:40Z urn:sha1:59fc2e62cbfb94e901ac24c0d85a7bec738473e0 Two QA-found bugs fixed: - mktext now collapses runs of whitespace in verse text to a single space (and trims), matching lectio's Fields-based rendering. The Vulgate source has occasional double spaces that were leaking into the output. - Regenerated gen/ with the hermetic, alias-fixed clectio-gen: the generator no longer picks up the user's stale books.ini (which had silently dropped ~30 EF Ember-day lessons, e.g. St Lawrence-common Sir 45, Osee/Hosea 14, 2 Esdras/Nehemiah 8). Full range 2025-2054 now has 0 dropped readings. Verified vs lectio: OF and EF 2026 are byte-identical (day names + verse text, 0 mismatches); range boundaries 2025-01-01 / 2054-12-31 match; ASAN + UBSAN clean over leap days, boundaries and edge cases; bad input never crashes.
