Well, as can be seen above the TPCL Expression Editor is taking shape. After taking a look at the R5RS specification I decided that going about trying to fit TPCL expressions into categories would be artificially limiting and error prone. The result is that I plan on displaying all available tpcl blocks, both built-in and custom templates, in a tree control. These will be inserted by clicking on an expansion point and choosing the "Insert" option. I will also likely add a small menu within the insert menu that will expand into a subset of the available built-in expressions so that booleans, literals, arithmetic functions and other similar simple expressions can be quickly and easily accessed (thanks, mithro, for that idea)Anyway...things are progressing well. Expressions created with the editor are now formatted nicely with newlines and indentation so that the output is still human readable. Anyway. More work tomorrow.
