ffcx.main
Command-line interface to FFCx.
Parse command-line arguments and generate code from input UFL form files.
Functions

Run ffcx on a UFL file. |
- class ffcx.main.Sequence
Bases:
Reversible,CollectionAll the operations on a read-only sequence.
Concrete subclasses must override __new__ or __init__, __getitem__, and __len__.
- count(value) integer -- return number of occurrences of value
- index(value[, start[, stop]]) integer -- return first index of value.
Raises ValueError if the value is not present.
Supporting start and stop arguments is optional, but recommended.
- ffcx.main.arg_type
alias of
int
- ffcx.main.get_options(priority_options: dict[str, dtype[Any] | None | type[Any] | _SupportsDType[dtype[Any]] | str | tuple[Any, int] | tuple[Any, SupportsIndex | Sequence[SupportsIndex]] | list[Any] | _DTypeDict | tuple[Any, Any] | int | float] | None = None) dict[str, int | float | dtype[Any] | None | type[Any] | _SupportsDType[dtype[Any]] | str | tuple[Any, int] | tuple[Any, SupportsIndex | Sequence[SupportsIndex]] | list[Any] | _DTypeDict | tuple[Any, Any]][source]
Return (a copy of) the merged option values for FFCX.
- Parameters:
priority_options – take priority over all other option values (see notes)
- Returns:
merged option values
Note
This function sets the log level from the merged option values prior to returning.
The ffcx_options.json files are cached on the first call. Subsequent calls to this function use this cache.
Priority ordering of options from highest to lowest is:
priority_options (API and command line options)
$PWD/ffcx_options.json (local options)
$XDG_CONFIG_HOME/ffcx/ffcx_options.json (user options)
FFCX_DEFAULT_OPTIONS in ffcx.options
XDG_CONFIG_HOME is ~/.config/ if the environment variable is not set.
Example ffcx_options.json file:
{ “epsilon”: 1e-7 }
