FQHETorusBosonsWithTranslations provides exact diagonalization for bosons on a torus geometry and any generic two body interaction. It fully supports magnetic translations in both directions. It is the bosonic counterpart of FQHEFermionsTorusWithTranslation (see this code for additional details). Typical usage is

$PATHTODIAGHAM/build/FQHE/src/Programs/FQHEOnTorus/FQHETorusBosonsWithTranslations -p 4 -l 8 --use-lapack --interaction-file pseudopotentials_delta.dat --all-points

pseudopotentials_delta.dat is the two body pseudopotential file that looks like

   Name = laughlin
   Pseudopotentials = 1.0

The spectrum will be stored in a file bosons_torus_laughlin_n_4_2s_8_ratio_1.000000.dat. It should look like
