From 85bf381f6a2bdf475eaf469fa2841c0422ed5605 Mon Sep 17 00:00:00 2001 From: Jose Antonio Ortega Ruiz Date: Thu, 3 Sep 2015 04:21:50 +0200 Subject: guile: pretty printing evaluation results (#64) We use the same trick as chicken for guile, and pretty-print the evaluation results before writing them. The trick wasn't working at all until i specified a value for the undocumented keyword parameter `#:max-expr-width`, which makes me think i might be missing something. --- geiser/evaluation.scm | 16 +++++++++------- 1 file changed, 9 insertions(+), 7 deletions(-) (limited to 'geiser/evaluation.scm') diff --git a/geiser/evaluation.scm b/geiser/evaluation.scm index 21f8772..f28fb28 100644 --- a/geiser/evaluation.scm +++ b/geiser/evaluation.scm @@ -49,9 +49,10 @@ (ge:set-warnings 'none) -(define (write-result result output) - (write (list (cons 'result result) (cons 'output output))) - (newline)) +(define (stringify obj) + (object->string obj + (lambda (o . ps) + (pretty-print o (car ps) #:max-expr-width 1000)))) (define (call-with-result thunk) (letrec* ((result #f) @@ -61,8 +62,9 @@ (with-fluids ((*current-warning-port* (current-output-port)) (*current-warning-prefix* "")) (with-error-to-port (current-output-port) - (lambda () (set! result (thunk))))))))) - (write-result result output))) + (lambda () (set! result (map stringify (thunk)))))))))) + (write `((result ,@result) (output . ,output))) + (newline))) (define (ge:compile form module) (compile* form module compile-opts)) @@ -79,7 +81,7 @@ (thunk (make-program o))) (start-stack 'geiser-evaluation-stack (eval `(,thunk) module)))) - (lambda vs (map object->string vs)))))) + (lambda vs vs))))) (call-with-result ev))) (define (ge:eval form module-name) @@ -87,7 +89,7 @@ (ev (lambda () (call-with-values (lambda () (eval form module)) - (lambda vs (map object->string vs)))))) + (lambda vs vs))))) (call-with-result ev))) (define (ge:compile-file path) -- cgit v1.2.3
