ALT Creates a new pict by aligning the descent and ascent lines of each adjacent pair of picts. That is, each pict is vertically positioned such that its ascent line (as reported by pict-ascent) is aligned with the previous pict’s descent line (as reported by pict-descent). Each pict is horizontally positioned so that it immediately follows the previous pict’s last element (as reported by pict-last). The alignment rules used by line-append make it useful for aligning multiline blocks, especially code that uses expression-based indentation. Examples: > (define (tt str) (text str 'modern 16)) > (line-append (vl-append (tt "(define some-example-with-a-long-first-line") (tt " (values ")) (vl-append (tt "(some-expression)") (tt "(another-expression)") (tt "note-the-close-paren!")) (tt ")"))

ALT Alexis King: Just because your other question was more on-topic here than wherever you initially asked it (though it doesn’t seem to have been migrated to me?) doesn’t mean other questions are, too! Please read the help center to see what sorts of questions we focus on here. AlMa1r: Just because you feel an urge to exercise control but have no real control doesn't mean you should complain about every single closed question in retrospect. Please consult your soul before commenting.
