where form saves log?

[tueda]

As far as I remember, keep_log is the option to keep FORM's piped output (which could be in general gigantic) in memory, in order to show a proper error message when something wrong happens with FORM:

python-form/form/formlink.py

Lines 92 to 95 in 24a77ca

	The other argument ``keep_log`` indicates whether the log from FORM is
	kept and used as detailed information when an error occurs.
	If the value is >= 2, it specifies the maximum number of lines for
	the scrollback. The default value is False.

So, this is not what you want.

.str files are FORM's temporary files, used for storing big data that doesn't fit in memory, and will be deleted when FORM successfully exits.

FORM has the -l option to save logs, but it writes the log into the directory where the main .frm file is sitting, not in the current directory. For example,

import form

with form.open("form -l") as f:
    f.write('''
        On stats;
        Auto V p;
        L F = g_(0,p1,...,p6);
        trace4,0;
        .sort
    ''')
    print(f.read('F'))
    print(f.read("`NAME_'"))

writes the log to init.log in the directory which you can find by f.read("`NAME_'").
