fd1a7f2b36 A one-line if takes its else on the next line, lambdas state their types, a restart's report sits on its header, Dir.north names an enum member, messages spell types in the code's syntax, adjacent globals convert adjacent, and a bad map key is one error 2026-09-26 00:07:28 +07:00
dca29a5605 A .fln file's common mistakes are answered in .fln terms, a bare () in a body slot does nothing, and the syntax gaps found writing by hand are listed in TODO.org 2026-09-25 23:44:04 +07:00
7e48f1eaf5 Eight hand-written .fln programs run the same on both backends and through a conversion to parens and back 2026-09-25 23:34:16 +07:00
8fe8062a0c Hand-written .fln programs exist, flan convert writes corpus-shaped paren text, and several .fln diagnostics suggest .fln spellings 2026-09-25 23:26:53 +07:00
0e26af2107 A macro body counts as run in order only when nothing outside its templates depends on how the body splits into arguments, a let whose longer scope would reach a macro naming it stays in a do: block, and converted programs with shadowed names and macro bodies print what their paren originals print 2026-09-25 23:00:27 +07:00
55ab1a98ae A macro whose definition splices its body into a do, and comment, count as bodies run in order where the .fln printer writes a let flat, and a struct-pattern let renames and flattens like a plain one 2026-09-25 22:39:50 +07:00
0b80c1956f A let in .fln is always flat and a line indented under one is refused, the printer renames a let's name a later statement means otherwise or puts the let in a do: block, and a one-argument and/or prints as its argument 2026-09-25 22:23:37 +07:00
4c336687ef Master's error recovery is merged, and the refusal memos are consulted only where a refusal is raised 2026-09-25 17:03:32 +07:00
30373ffda5 A converted comment stays with the form it was written beside when the printer reorders or splits bindings, the round trip checks each comment's form, and a snippet's first line sets its left edge 2026-09-25 16:17:12 +07:00
25e303caf4 Master's indented reader is merged, and its x += v over a place with a call in it reads as update, evaluating the place once 2026-09-25 15:56:51 +07:00
8200120bf3 flan convert keeps comments and number spellings in both directions, and a .fln message quotes the text as written, with let-bound match, if and block calls read as values 2026-09-25 15:47:29 +07:00
074b2da6f3 The indented reader refuses a continuation line that is not deeper than its statement, takes one-line statements in arms, then/else and defer, typed lets and bare-name blocks, and names the shape it wanted where it used to say two values cannot sit side by side 2026-09-25 15:30:52 +07:00
d7016f91c7 A .fln file is read by an indented reader that yields the paren reader's forms, every program entry point picks the reader by extension, and flan convert prints either syntax as the other 2026-09-25 15:04:32 +07:00
