Sourceval next_ident_away_from : Names.Id.t -> (Names.Id.t -> bool) -> Names.Id.t

Avoid clashing with a name satisfying some predicate

Sourceval next_ident_away : Names.Id.t -> Names.Id.Set.t -> Names.Id.t

next_ident_away original_id unwanted_ids returns a new identifier as close as possible to the original_id while avoiding all unwanted_ids.

In particular:

if original_id does not appear in the list of unwanted_ids, then original_id is returned.
if original_id appears in the list of unwanted_ids, then this function returns a new id that:
- has the same root as the original_id,
- does not occur in the list of unwanted_ids,
- has the smallest possible subscript.

where by subscript of some identifier we mean last part of it that is composed only from (decimal) digits and by root of some identifier we mean the whole identifier except for the subscript.

E.g. if we take foo42, then 42 is the subscript, and foo is the root.

Avoid clashing with a name already used in current module

Sourceval next_global_ident_away : Names.Id.t -> Names.Id.Set.t -> Names.Id.t

Avoid clashing with a name already used in current module but tolerate overwriting section variables, as in goals

Sourceval next_name_away : Names.Name.t -> Names.Id.Set.t -> Names.Id.t

Default is default_non_dependent_ident
