    Save the information about the current session to a text file.

save_all(outfile=None, clobber=False)
outfile - str or file-like, optional
clobber - bool, optional

This differs to the `save` command in that the output is human readable. Three consequences are:

numeric values may not be recorded to their full precision
data sets are not included in the file
some settings and values may not be recorded (such as header information).

Write the current Sherpa session to the screen:

>>> save_all()

Save the session to the file 'fit.sherpa', overwriting it if it already exists:

>>> save_all('fit.sherpa', clobber=True)

Write the contents to a StringIO object:

>>> from io import StringIO >>> store = StringIO() >>> save_all(store)

PARAMETERS

The parameters for this function are:

Parameter
Definition
outfile
If given, the output is written to this file, and the

`clobber` parameter controls what happens if the file already exists.

`outfile` can be a filename string or a file handle (or file-like object, such as StringIO ) to write to. If not set then the standard output is used.
clobber
If `outfile` is a filename, then this flag controls whether an existing file can be overwritten ( True ) or if it raises an exception ( False , the default setting).

Notes

This command will create a series of commands that restores the current Sherpa set up. It does not save the set of commands used. Not all Sherpa settings are saved. Items not fully restored include:

grating data is not guaranteed to be restored correctly,
data changed from the version on disk - e.g. by calls to `set_counts` - will not be restored correctly,
any optional keywords to comands such as `load_data` or `load_pha` ,
user models may not be restored correctly,
and only a subset of Sherpa commands are saved.

Changes in CIAO

Any set_psf calls are now included in the output file. The filter is no-longer included if it does not exclude any data, and the code tries to recreate manually-created datasets (e.g. use of `dataspace1d` or `load_arrays` ), but not all situations are handled. XSPEC table models are now correctly restored.
