  • It is possible to customize what happens to the focus of the current window when the type checking is performed and type errors are detected, now the user can choose between two options: 1) the current window stays focused or 2) the focus goes to the *idris-notes* buffer. The true or false value of the variable idris-stay-in-current-window-on-compiler-error controls this behaviour.


  • The variable idris-packages has been renamed to idris-load-packages. If you have this as a file variable, please rename it.
  • The faces idris-quasiquotation-face and idris-antiquotation-face have been added, for compiler-supported highlighting of quotations. They are, by default, without properties, but they can be customized if desired.
  • Active terms can now be right-clicked. The old "show term widgets" command is no longer necessary, and will be removed in an upcoming release.
  • The case split command can be run on a hole, causing it to be filled with a prototype for a case split expression. Case-splitting a pattern variable has the same effect as before.
  • There is support for the interactive elaborator, which may replace the interactive prover in a future release. To use this, set idris-enable-elab-prover to non-nil.
