Changelog History

  • v1.2.1.0 Changes

    November 14, 2020
    • Introduces gregorianDateTime, which is the reverse of julianDay: given a JD, return a tuple with (year, month, day, decimalHour).
  • v1.2.0.0 Changes

    September 14, 2020

    BREAKING CHANGE: splitDegrees now takes options that reflect the options in the underlying library.

    • Constructors for JulianTime and SiderealTime are now exposed.
    • Introduce SplitDegreesOption enum for all options one can split degrees with; amends splitDegrees to take
      said options as the first argument.
    • splitDegreesZodiac is unchanged, though a mere veneer for the now more powerful splitDegrees.
    • Since splitDegreesZodiac goes the extra enum-mile to provide human-readable zodiac names, and the underlying
      library can also split on Nakshatras, we now include the NakshatraName enum. Names are from wikipedia
      and I saw some variants, so please forgive any mispellings!
  • v1.1.0.0 Changes

    September 12, 2020

    BREAKING CHANGE: the Coordinates type has been retired, in favor of the more specific
    GeographicPosition and EclipticPosition. calculateCoordinates is now calculateEclipticPosition,
    and the calculateCusps* family now takes a GeographicPosition as part of its inputs.

    • Introduces an Internal module with types and helpers that this library introduces,
      which are not native to the underlying C library. Import at your own risk! (the "curated"/
      "stable" ones are re-exported by the main module.)
      • Deprecates the Coordinates type, in favor of EclipticPosition.
    • Introduces functions to calculateEquatorialPosition and calculteObliquity at a given time,
      👍 as well as types that better convey the different types of positions (EquatorialPosition, ObliquityInformation).
    • Some astrology helpers: convert between equatorial and ecliptic (and vice-versa,)
      obtain the Delta Time effective at a given moment, obtain the house position of a given body.
      ( Note: the calculateHousePosition function is more useful for working near the polar circles or for bodies
      off of the ecliptic -- the ARMC and obliquity need to be calculated or provided, it's simpler
      if you already have the cusps: just check which cusps a given longitude falls between -- no need for
      this function!)
  • v1.0.0.0 Changes

    September 07, 2020
    • 🔨 Refactor the calculateCusps function:
      • Return a simple list of cusps. This allows for future implementations of exotic systems that have more (or fewer?) cusps, and hews closer to regular usage (which iterates over the cusps.)
      • The house system comes first, to allow for more ergonomic partial application for uses where one system is the "default" (e.g. traditionalCusps = calculateCusps Placidus.)
    • ⚡️ Cleans up haddocks, adds many links to the original docs (and notes the headings, since updates to those seem to break hyperlinking?)
  • v0.3.1.0 Changes

    September 07, 2020
    • 🛠 Fixes occasional segmentation fault (caught most often in the more memory-strapped CI server than in my computer,)
      📦 caused by using alloca for the error string and, when no error string was populated, ending with undefined
      📚 behavior. Now we explicitly allocate the 256 chars that the documentation and C sources recommend, which seems to be always
      freed by Haskell, vs. leaving a hole somewhere when the underlying library fails to terminate the string.

    👀 See notes in #9

  • v0.3.0.0 Changes

    September 05, 2020
    • ⬆️ Upgrades to v2.09.03 of the C library, to incorporate some bug fixes that seem marginally related
      to random breakage I've seen; read more at: https://www.astro.com/swisseph/swephprg.htm#_Toc49847971
    • Introduces withoutEphemerides which sets the ephe path to NULL (via the also new setNoEphemeridesPath)
      👀 and takes care of calling closeEphemerides. Use this or withEphemerides for memory safety,
      only call the functions directly if you really know what you're doing (i.e setting/closing ephemerides
      in some other manner.)
    • Both calculation functions are now IO computations, to reflect the fact that they may interact
      with ephemeris data and allocate memory that closeEphemerides has to free.
    • More closely reflects the underlying behavior for calculating cusps: it may return
      cusps in the Porphyrius system if given a point for which the chosen system fails. To
      more explicitly reflect this, we now have calculateCuspsStrict which returns a Left value
      if the requested house system couldn't be used. calculateCuspsLenient always returns a calculation,
      0️⃣ and is aliased to calculateCusps as the "default" method.
    • Since the calculation may have changed the house system, we now return a systemUsed entry
      in the CuspsCalculation record.

    CI continues to not work, despite my insane efforts to resolve.

  • v0.2.0.0 Changes

    September 04, 2020
    • Introduces withEphemerides for bracketed access to the ephemeris directory.
    • 🔄 Changes the signature of calculateCusps to return a Left value if the underlying library
      is unable to calculate the cusps.
    • Introduces "monadic" versions of the calculations that work with instances of MonadFail:
      calculateCuspsM and calculateCoordinatesM
    • 👌 Improves test coverage with property testing.
  • v0.1.0.2 Changes

    August 13, 2020

    🏗 The build in hackage was failing, it seems like all header files need to be explicitly stated so they're included in the tarball!

  • v0.1.0.0 Changes

    August 12, 2020
    • Bundles the C code for v2.09.01 of Swiss Ephemerides -- refer to that page and related documentation for other possible additions to this package!
    • 🚀 First release with basic bindings to calculate the coordinates of bodies between the Sun and Chiron, plus cusps and major angles -- calculateCoordinates and calculateCusps, respectively.
    • 👀 The functions setEphemeridesPath and closeEphemerides are provided to initialize (important) and release (less important) resources related to caching calculations and locating the data files for ephemerides.
