b814aca187 A kept when or else-less chain over an Option arm is that Option, flattened one level, unless an Option of it is wanted. 2026-09-26 18:02:43 +07:00

0c7a53f526 A pipe into a language word is refused, and a pipe the next operator or an as swallows is refused with the bracketed form as the fix. 2026-09-26 17:11:15 +07:00
cb60df1dc0 A T is wrapped in Some wherever a T? is wanted, one level at a time and never unwrapped back. 2026-09-26 17:11:12 +07:00
5a3d480edf In .fln, x |> f(a) reads as f(x, a), below or, with the Emacs mode indenting and marking pipe lines. 2026-09-26 16:58:53 +07:00
adfab2d482 A narrowed name keeps its assignability, a local whose address is taken or that a fn assigns is not narrowed, a trailing ? tests a whole chain, and the optional refusals name the test to write. 2026-09-26 16:08:16 +07:00
d252eee2b2 In .fln x? tests that a value is present and narrows a local Option to its payload in the block it guards, and e? as g names what a test found. 2026-09-26 15:48:36 +07:00
178c129c97 A .fln name carries no ? or !, and .fln has T?, x ?? d, x!, if let over a plain name and a?.b chaining. 2026-09-26 14:54:58 +07:00
7db1a81d1f Builtins, prelude, vendor and raylib predicates are named with is- or has- and no name carries a ? or !. 2026-09-26 14:34:36 +07:00
5038c5954a get on a String is refused as at is, a dyn get's trap names get, a kept else-less form beside a number is blamed at itself in arithmetic and comparisons, and a kept if-let chain with no final else gives an Option. 2026-09-26 13:40:16 +07:00
1b588df6b5 Master is merged into the when, get and if let lane after the review fixes. 2026-09-26 13:09:24 +07:00
79430aca77 A lambda's last form is checked at the return its position wants, a call's arguments and a kept cond with no else keep a when as an Option, a when used as an arithmetic operand is blamed itself, elif let reads and prints as a nested if-let, and dyn get over text or a vec runs at's own runtime body. 2026-09-26 13:09:21 +07:00
1243504ac6 .fln has let groups, grid[r c] indices and a not prefix, and a binding lines up under the let's first name. 2026-09-26 13:01:34 +07:00
a3899f3ecb Master is merged into the when, get and if let lane for the review fixes. 2026-09-26 12:53:34 +07:00
b1cba196b9 A .fln comparison chain may mix < with <=, or > with >=, reading as the and of its tests with every operand evaluated once, left to right, as a < b < c is, and the printers write that and back as the chain. 2026-09-26 12:19:03 +07:00
62fd7b19bc Master is merged into the when, get and if let lane. 2026-09-26 12:13:55 +07:00
5ee433a38f A kept when answers an Option, get is a checked lookup over arrays, slices, Vecs and dyn, and if let reads as a two-arm match in both syntaxes. 2026-09-26 12:12:48 +07:00

17ff7cb348 A binding ends its let's bindings only when its value ends in an open block, the message names the let's own line, and Emacs offers no binding column after such a value 2026-09-26 11:11:32 +07:00

c4452fc500 Merge master into the bit operators lane 2026-09-26 11:04:32 +07:00
473bf0a2b7 The bit operators are && || ^^ ~~ in .fln at Python's precedence, take integers only on typed and dyn values, and popcount, leading-zeros, trailing-zeros and the rotations exist on both backends. 2026-09-26 10:49:54 +07:00
63dc853121 A binding whose value is a block ends its let's bindings, a tab between let and its name is refused, and only a binding-shaped line under a let gets the alignment advice 2026-09-26 10:39:05 +07:00
fc463cf320 The .fln reader refuses loop and recur, flan convert refuses a .flan file that uses them, and every loop outside recur.flan is a while or until. 2026-09-26 10:31:53 +07:00
0e9d647aca A let's binding lines must line up with its first name, may name an operator word in parentheses, are refused clearly after a block value, and at the top level may be a typed name alone 2026-09-26 09:56:54 +07:00

36156c9de9 A dyn value takes .field and [:key] as get and put, and a class instance refuses a slot it does not have 2026-09-26 09:28:25 +07:00
12cd4feff0 A .fln let takes more bindings on the lines indented under it, a top-level one more globals, and flan convert writes runs of short bindings that way 2026-09-26 06:26:36 +07:00
f39612bc7c Code a request sends without :syntax is read in its file's syntax, or the program's when it names none, and a dotted dyn name points to its accessor. 2026-09-26 06:21:07 +07:00
f91ed8ad27 Indices in .fln separate like a vector's elements, by spaces between single values or by commas 2026-09-26 06:19:59 +07:00
6e006fce27 not is a prefix word in .fln, looser than comparisons and tighter than and, with not(x) still a call 2026-09-26 06:18:11 +07:00
b1404727b6 A lambda with a block prints wherever it is last in its brackets, an element after a block lambda is refused as not last, and TAB offers no column of a block whose brackets have closed 2026-09-26 06:09:47 +07:00

605eb97e75 A dyn value's .field and [:key] read as get and assign as put. 2026-09-26 05:52:56 +07:00
702ebdc9c5 In a .fln file a top-level let is a global and def is refused, while a let in a block or an evaluated expression stays local. 2026-09-26 05:39:59 +07:00
cde4f2ab1b A .fln file writes classes and methods as class, generic, multi and method headers, and flan convert prints them so. 2026-09-26 05:39:59 +07:00
905a4c53be A struct or union fits on one line, struct Pt(x: i32, y: i32), and flan convert writes that form when it fits. 2026-09-26 05:39:59 +07:00
72c73117d6 A .fln file writes a type alias as type Row = Vec(i32), and flan check prints nothing for a file that checks unless given --defs. 2026-09-26 05:39:59 +07:00
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
6e56fce7fa flan-fln-mode reads a lambda's block inside brackets as statements, and the spec and manual write lambdas with => 2026-09-26 05:27:28 +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
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

3e504deb6f An arm is checked at the other arm's type first and meets it at the join only when refused there, so every program master accepts keeps its type and value while arms still meet in either order 2026-09-25 23:10:16 +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
