GAMBAS is a free implementation of a graphical development environment (IDE) based on a BASIC interpreter and a full development platform. It is heavily inspired by Microsoft Visual Basic and Java.

The following pieces of code were borrowed and adapted:

  • The natural string comparison algorithm was adapted from the algorithm made by Martin Pol. See for more


  • The hash table implementation was adapted from the glib one.

  • The HTML entities parsing in gb.gtk comes from KHTML sources.

  • The gb.image.effect sources are adapted from KDE 3 image effect routines.

  • The gb.clipper library embeds the Clipper library. See for mode details.

  • The function that computes the Easter day of a specific year uses an

    algorithm made by Aloysius Lilius And Christophorus Clavius.

  • The blurring algorithm is based on the StackBlur algorithm made by Mario Klingemann. See for more details.

If I forget some borrowed code in the list above, just tell me.

Enjoy Gambas!
