      Separate, add systems input-output, math-high, mathematics · f0472919
      Liam M. Healy authored
      Separate, add systems new systems that were in the old monolithic
      antik.asd: input-output, math-high, mathematics. Make the retrieval of
      earth orientation parameters (for calibrating UT1 timescale) a
      connected system when Drakma is loaded.

      Move arithmetic methods that use funcall-dyadic, organize tests · 514bbac1
      Liam M. Healy authored
      Calls to funcall-dyadic only should happen once that function has been defined, and it is meant to handle grid/pq case anyway, so the arithmetic methods (t t) that called it have been moved to where it is defined, which is in the physical-dimension system. Tests have been reorganized, and all pass.

      System physical-dimension, requires grid, loadable · e670f326
      Liam M. Healy authored
      As an interim step in separation of systems, physical-dimension is now loadable if grid is loaded. All grid tests pass. However, there are failures basic Antik functions and tests are not properly loaded.

      Fix #'right-angle · ceee01b4
      Liam M. Healy authored
      The function right-angle will find an arbitrary vector in the plane
      perpendicular to a given vector. It would possibly return the zero
      vector. This version is shorter and should always produce a non-zero
      vector.

      Fix iterate extension to increment properly · e85d75dc
      Liam M. Healy authored
      In the iterate extension :matrix-element, the first element of
      following rows was repeated due to an error in the logic of the
      expansion. 
      Example: 
      (defparameter m1 #m(1 2 3 ^ 0 6 8))
      (iter:iter (iter:for e :matrix-element m1) (princ e) (princ " "))
      1.0 2.0 3.0 0.0 0.0 6.0 8.0
      This is now fixed.
      
      Problem reported on SO, and sent to mailing list by Joshua Taylor.

      Systems of units names in the units table · 6640ba5e
      Liam M. Healy authored
      Systems of units are no longer dynamic variables or setting default
      systems symbol macros. Instead, the systems' names are placed in the table
      with unit names, *unit-information*.

      Fix and simplify pqval (physical-quantity) for non scalar-dimension · 67cea885
      Liam M. Healy authored
      There was an error in #'pqval when the argument was a non scalar-dimension grid. This has been fixed by moving the binding of 'units into the then clause of the if (it wasn't used in the else clause anyway, and that's what caused the error). The units construction for non-scalar dimension makes use of grid:map-grid and is simpler.

      New macro define-derived-system-of-units · 250eedb5
      Liam M. Healy authored
      The new macro define-derived-system-of-units is like define-system-of-units except that it also takes a base system of units from which to derive the new system of units, and does not default to the current system of units.

      Complete changes for system of units specification · bc899205
      Liam M. Healy authored
      - Fix number of arguments in calls to functions that no longer take
        sysunits or addition-units arguments.
      - Change nf-option so that it works dynamically, i.e., the default
        value is retrieved at run time, not macro expansion time.
      - Name argument to parameter-value must be in the keyword package.
      - The system of units can be nil, in which case an unreadable object
        is printed, with the sexp for the dimensions printed.  
      - New variable *basis-physical-dimensions* used to give the dimension
        without units.
      - All nf definitions in a separate file.
      
      System now compiles and loads without error.

      System of units specification is through an nf-option · 6ca09dfb
      Liam M. Healy authored
      The specification of the system-of-units is through an nf-option, and
      no longer passed as arguments to functions.  Systems of units (with or
      without augmented units) are made via make-sysunits or
      define-system-of-units, set-default-system-of-units that call it.
      
      This does not compile.
