/td>read-print: 'canonicalize-comment' leaves top-level comments unchanged....This lets users use three leading semicolons, for instance, in top-level comments. * guix/read-print.scm (canonicalize-comment): Add INDENT parameter and honor it. (pretty-print-with-comments): Change default value of #:format-comment. Call FORMAT-COMMENT with INDENT as the second argument. * tests/read-print.scm: Adjust test accordingly. Ludovic Courtès 2022-08-08read-print: Add code to read and write sequences of expressions/blanks....* guix/read-print.scm (read-with-comments): Add #:blank-line? and honor it. (read-with-comments/sequence, pretty-print-with-comments/splice): New procedures. * tests/read-print.scm (test-pretty-print/sequence): New macro. Add tests using it.
