(require mrlib/syntax-browser ) package: gui-lib

procedure
( render-syntax/snip stx
[ #:summary-widthsummary-width])
→(is-a?/c snip% )
stx:syntax?
summary-width:(or/c #f0(integer-in 3#f)+inf.0)=32

Constructs a snip% object that displays information about stx.

The summary-width parameter controls the width (in characters) of the syntax object that is shown before the triangle is turned down. If it is #f, the value of the print-syntax-width parameter is used.

Changed in version 1.59 of package gui-lib: Added summary-width argument and changed default width to 32.

stx:syntax?

Uses render-syntax/snip’s result, together with a frame and editor-canvas to show stx.
