[Octave-bug-tracker] [bug #38149] regexp doesn't return empty tokens -- they just disappear

[Rik]

Follow-up Comment #13, bug #38149 (project octave):

Okay, at least I got 1 out of 5 answers.

Let's try the following:


te = regexp ('abc', 'abc(z?)', 'tokenExtents');
celldisp (te)

te = regexp ('abce', '((a)(z)?b(c)(z*))(z)?(e)?', 'tokenExtents');
celldisp (te)

[T, TE, NM] = regexp (sprintf('%s','John Davis\nRogers, James'),
'(?<first>\w+)\s+(?<last>\w+)|(?<last>\w+),\s+(?<first>\w+)', 'tokens',
'tokenExtents', 'names');

celldisp (T)
celldisp (TE)
NM(1).first
NM(1).last
NM(2).first
NM(2).last
