Abstract: Semantically-powerful views, formatted program text, and structural operations on programs are powerful tools for helping users understand and edit programs. The Pan Program Presenter provides these facilities, including elision and display of program annotations, in an incremental, portable implementation. It provides novel languages for specifying program appearance, including both a succinct, easy-to-use form and a more powerful, extensible form.
