normalized_names

normalized_names(pos='j', neg='k')

Returns a normalized identifier string for every species in the collection, in catalogue order. Each name is lowercased and has "+" replaced by pos and "-" replaced by neg, producing strings that are valid variable names in C, Fortran, and Python. With the defaults, "HCO+" becomes "hcoj" and "e-" becomes "ek". The j/k choice matches the convention used by get_fidx and avoids the charge-marker-vs-element-letter collision (e.g. Sn tin vs S-).

Parameters

pos : str, optional

Replacement for "+", by default "j".

neg : str, optional

Replacement for "-", by default "k".

Returns

Vector[str]

Normalized, code-safe identifier string for each species, in catalogue order.
