1a97dfff77 A .fln file writes a condition's parent as struct DiskFull :parent IoError, a macro as macro repeat(i, n, & body) and a loop as loop x = a, y = b, and flan convert prints them so. 2026-09-26 05:39:59 +07:00
6c32383539 Typed lambdas bind a generic's CFn variables, a local shadows an enum of its name, the lambda-in-brackets fix is the typed let that compiles, an else deeper than a one-line if or after else-if is refused by name, a block if takes a one-line else, and messages spell every type in the code's syntax 2026-09-26 00:36:21 +07:00
fff1c0b9c3 Merge master: return-type inference beside the syntax-following type spellings 2026-09-26 00:27:59 +07:00
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
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
2135f6d37f Merge branch 'master' into worktree-agent-a46233a32d1912c78 2026-09-25 23:27:55 +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
e18b28be3e Master is merged into the flat-let lane 2026-09-25 22:49:39 +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
47cc213b42 Return types read off the body and the converter's latest fixtures live together 2026-09-25 22:14:32 +07:00
1cfe97548a test/syntax/algorithms.fln is the converter's fixture again 2026-09-25 22:00:44 +07:00
bb800903d8 Return types read off the body and frame-escape refusals live together 2026-09-25 21:49:14 +07:00
94134da25a Dyn containers print without a space after the bracket, queued 2026-09-25 21:32:46 +07:00
d991e1986c Flat lets and one-argument and/or in the .fln printer are queued 2026-09-25 21:27:50 +07:00
df7078d586 A _ function's exits combine exactly as an if's arms do, a refused _ body or loop is collected with every other error, and the placeholder type never leaves the checker 2026-09-25 20:37:50 +07:00
8fdf8513fd A _ body's errors are reported with every other error in the file, a literal return takes the type of the other exits, and a recursive _ function that gives nothing returns () 2026-09-25 20:17:44 +07:00
ff88b9dad6 A defn whose return slot is _ (or a .fln fn with no arrow) takes its return type from its own body, recursion through such functions is refused by name, and a stale caller of one is told which line changed its type 2026-09-25 17:09:13 +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
