read_eppic_i_file

PlasmaCalcs.hookups.eppic.eppic_io_tools.read_eppic_i_file(filename='eppic.i', *, eval=True)

Parse EPPIC input from the file, returning (dict of global vars, dict of dists).

dict of global vars has {varname: value} for all pairs not inside a distribution.

dict of dists has {N: {varname: value} for all pairs in dist} for each dist;

for each varname in a dist, ensure varname ends with str(N) (append it if necessary).

the N’s will all be stored here as ints.

Arguments:

filename: string, default ‘eppic.i’

file to read from.

eval: bool, default True

whether to attempt to evaluate the values,

using ast.literal_eval (safer but less flexible than eval).

if True, try to evaluate values but use strings if evaluation fails.

if False, values will remain as strings.

Notes:

- file formatting:

- semicolons (;) are used for comments. (idl format)

- ignore blank lines & lines that don’t assign a variable (missing ‘=’)

- ignores all leading & trailing whitespace in vars & values.

- special var: “dist{N}”, where N is any integer (or empty string).

- after finding this, start storing lines in result[“dist{dist}”]

- e.g. “dist1=1” –> result[“dist1”][var] = value.

same behavior if “dist=1”.

- additionally, N will be appended to var names if it is not already there,

e.g. “dist1=1”, “var=7” –> result[“dist1”][“var1”] = 7

- if “dist{N}” appears AGAIN, use it as the new dist; store lines in result[“dist{N}”]

- special var: “fndist”

- if found, stop storing lines in result[“dist{dist}”]
