Haskell Hall Symbols Library
Quickstart
Make new stack project and move to project directory.
% stack new hmRepl
% cd hmRepl
Edit resolver part like below
# resolver: lts-16.6
resolver: nightly-2020-07-23
Edit dependencies part of package.yaml like below.
dependencies:
- base >= 4.7 && < 5
- matrix-as-xyz
- symmetry-operations-symbols
- hall-symbols
Then start repl.
% stack repl
Setup packages and load modules.
repl> :m Data.Matrix.AsXYZ Data.Matrix.SymmetryOperationsSymbols Crystallography.HallSymbols
Use like below.
-- print General Positions.
repl> prettyXYZ <$> fromHallSymbols' "C -2yc"
["x,y,z","x+1/2,y+1/2,z","x,-y,z+1/2","x+1/2,-y+1/2,z+1/2"]
repl> fromHallSymbols' "C -2yc" >>= fromMatrix'
[" 1 "," c x,0,z"," t (1/2,1/2,0) "," n (1/2,0,1/2) x,1/4,z"]
Or use like below.
-- print Generators
repl> prettyXYZ <$> generatorsOfHallSymbols "C -2yc"
["x,y,z","x+1/2,y+1/2,z","x,-y,z+1/2"]
repl> generatorsOfHallSymbols "C -2yc" >>= fromMatrix'
[" 1 "," t (1/2,1/2,0) "," c x,0,z"]
