LispPad

LispPad is a simple, lightweight, integrated development environment for developing and running Scheme code. The language supported by LispPad is based on the R7RS standard for Scheme.

Features

• A fully integrated Scheme interpreter
• A console with a read-eval-print loop to interact with the interpreter
• A text editor for writing Scheme code, supporting syntax highlighting, smart indentation, parenthesis matching, page guides, etc.

New features:

• New libraries: (lispkit csv), (lispkit match), (lispkit regexp), (lispkit gvector), (lispkit date-time)
• Extended (lispkit vector) and (lispkit list) libraries
• Support for let-keywords and let*-keywords in library (lispkit control)
• Support call tracing for individual procedures
• Include call traces in the session log

Bug fixes:

• Complete re-write of library import and export logic fixing numerous bugs and incompatibilities with R7RS
• Improved reporting of errors in library definitions
• Fixed output of multi-value results in the session window
