Due to their large masses, the production of heavy-flavour quarks can be computed perturbatively, thus providing a powerful tool to test the corresponding QCD calculations. Additionally, measurements of heavy-flavour hadrons are useful to reveal the details of heavy-quark fragmentation in pp collisions at LHC energies. Event-activity-dependent measurements of heavy-flavour production may shed light on the mechanisms of interplay between soft and hard processes. In this contribution, we present recent measurements of the ALICE experiment on charm-hadron production as a function of charged-particle multiplicity in pp collisions at various energies, including the measurements of charm baryon-to-meson production yield ratios. New results of D-meson production as a function of the transverse spherocity of the event, as well as of the transverse event-activity classifier RT, are also presented.
