The production of heavy-flavour hadrons in high-energy hadronic collisions is\na unique source of information on various aspects of quantum chromodynamics\n(QCD). Production of heavy-flavour hadrons in proton--proton collisions allows\nthe test of perturbative QCD models, while the comparison of mesons and baryons\nwith heavy-flavour quarks can differentiate between fragmentation scenarios.\nMultiplicity-dependent measurements allow for the understanding of semi-hard\nvacuum QCD effects, as well as to study the coalescence mechanisms of\nheavy-flavour quarks with light and strange quarks. Recent results from the\nALICE experiment in proton--proton collisions on the production of D mesons and\nleptons from the decay of heavy-flavour hadrons, as well as charmed baryons,\nare presented in this contribution. Furthermore, the multiplicity dependence of\nself-normalised heavy-flavour electron yields, as well as that of strange to\nnon-strange D-meson and charmed baryon-to-meson ratios are also shown.\n
