shows the daily tarot/astrology reading on-device: persistence, reading
computation, and UI screens, driven by the existing engine/interpreter
code linked in unchanged where possible.
Required engine-side changes to make that linking work:
- A compact low-precision ephemeris (lowprec_ephemeris.c) replacing the
vendored ~127KB Astronomy Engine, which doesn't fit the watch's ~64KB
app budget.
- Hand-rolled sqrt/atan2/sin/cos replacements for that ephemeris and
astro.c's Ascendant calculation - Pebble's statically-linked libm
hard-faults on real hardware under this app's -fPIE link for all four.
- narrative.c/guidance.c refactored from FILE*/fprintf onto snprintf-
based buffers, since Pebble's SDK blocks fprintf at compile time.
Bundles deck-engine, interpreter-cli, run-engine.sh/run-interpreter.sh,
img/, i18n/, LICENSE, README.md, and docs/reading.md into
dist/deck-in-a-dash-<version>-linux-<arch>.tar.gz. Version defaults to
the current git tag (vX.Y.Z), falling back to a 0.0.0-dev+<sha>
placeholder when untagged
- guidance.c now prints last, after the full spread; both it and main.c's
new Celtic Cross readout pull real Waite card meanings via tarot_data.c
instead of just naming cards.
- interpreter-cli gains --format text|html|json and --lang en|de, matching
deck-engine - required linking engine/src/tarot_data.c and i18n.c into
the interpreter binary (a narrow, documented exception to its earlier
"no engine .c files" policy) and writing German translations for
narrative.c's/guidance.c's own text.
Each of the day's top significant transits now gets a short sentence
describing what it classically means and which area of life its house
governs, condensed from Sepharial's Transits and Planetary Periods
(1920, public domain) plus a small table of traditional house
significations. The day-level line also shows its rank out of the 4
defined levels, e.g. "Notable (2/4)". Docs (CLAUDE.md, README,
docs/input-output-format.md, docs/reading.md) updated to match,
including a full worked example in docs/reading.md.
deck-engine gains --format json (language-independent, slug-based)
so a new dist/interpreter-cli can score how significant a day's
transits are without linking the engine itself — it depends only on
the JSON shape, via its own minimal parser. Also documents the full
reading pipeline end to end (CLAUDE.md, README, docs/) and adds
docs/reading.md, a non-technical explanation of what a daily reading
contains and means.
Every planet position now carries its whole-sign house (1-12); transits
report the natal house each transiting planet currently occupies rather
than a fresh "houses for right now" chart, matching how transits are
normally read. Surfaced in both text and HTML output, fully translated.
Plain-C, dependency-free engine that produces a personalized daily
Celtic Cross tarot spread and natal-chart/transit astrology reading,
plus a standalone CLI (dist/deck-engine) and run.sh wrapper. Includes
English/German output via a simple key=value translation format, and
docs/diagrams describing the architecture and I/O.
