Thanks for the status report! Michael Lucy writes: > Files I've added so far: > guile/modules/ice-9/peg.scm (I assume this is the right place to put this?) No, it should rather go under ‘module/language/peg.scm’, for the sake of consistency with other compiler front-ends. But see below. > PEG compiler: Works for all the grammars I've tested, no known bugs. > Currently compiles to Scheme code rather than Tree-IL for debugging. It should rather compiler to tree-IL, like other front-ends, which is very close to Scheme anyway. > 2. Tests aren't standardized (peg.test looks nothing like the other > .test files).

Try: $ ./meta/guile --no-autocompile > (use-modules (ice-9 peg)) It should trigger the debugger from where you can get a backtrace. Thanks, Ludo’.
