reset to what it was at the `#if`.\nAs a workaround, the code blocks in the alternative branches are parsed as part of the directives.\n\n# Querying\n\nThe grammar contains several [supertypes](https://tree-sitter.github.io/tree-sitter/using-parsers#static-node-types),\nwhich group multiple other node types under a single name.\n\nSupertype names do not occur as extra nodes in parse trees, but they can be used in queries in special ways:\n\n- As an alias, matching any of their subtypes\n- As prefix for one of their subtypes, matching its symbol only when it occurs as a production of the supertype\n\nFor example, the query `(expression)` matches the nodes `infix`, `record`, `projection`, `constructor`, and the second\nand third `variable` in this tree for `cats <> Cat {mood = moods.sleepy}`:\n\n```\n(infix\n (variable)\n (operator)\n (record\n (constructor)\n (field_update\n (field_name (variable))\n (projection (variable) (field_name (variable)))))))))\n```\n\nThe two occurrences of `variable` in `field_name` (`mood` and `sleepy`) are not expressions, but record field names part\nof a composite `record` expression.\n\nMatching `variable` nodes specifically that are expressions is possible with the second special form.\nA query for `(expression/variable)` will match only the other two, `cats` and `moods`.\n\nThe grammar's supertypes consist of the following sets:\n\n- [`expression`](./grammar/exp.js)\n\n Rules that are valid in any expression position, excluding type applications, explicit types and expression\n signatures.\n\n- [`pattern`](./grammar/pat.js)\n\n Rules that are valid in any pattern position, excluding type binders, explicit types and pattern signatures.\n\n- [`type`](./grammar/type.js)\n\n Types that are either atomic (have no ambiguous associativity, like bracketed constructs, variables and type\n constructors), applied types or infix types.\n\n- [`quantified_type`](./grammar/type.js)\n\n Types prefixed with a `forall`, context or function parameter.\n\n- [`constraint`](./grammar/constraint.js)\n\n Almost the same rules as `type`, but mirrored for use in contexts.\n\n- [`constraints`](./grammar/constraints.js)\n\n Analog of `quantified_type`, for constraints with `forall` or context.\n\n- [`type_param`](./grammar/type.js)\n\n Atomic nodes in type and class heads, like the three nodes following `A` in `data A @k a (b :: k)`.\n\n- [`declaration`](./grammar/module.js)\n\n All top-level declarations, like functions and data types.\n\n- [`decl`](./grammar/decl.js)\n\n Shorthand for declarations that are also valid in local bindings (`let` and `where`) and in class and instance bodies,\n except for fixity declarations.\n Consists of `signature`, `function` and `bind`.\n\n- [`class_decl` and `instance_decl`](./grammar/class.js)\n\n All declarations that are valid in classes and instances, which includes associated type and data families.\n\n- [`statement`](./grammar/exp.js)\n\n Different forms of `do`-notation statements.\n\n- [`qualifier`](./grammar/exp.js)\n\n Different forms of list comprehension qualifiers.\n\n- [`guard`](./grammar/exp.js)\n\n Different forms of guards in function equations and case alternatives.\n\n# Development\n\nThe main driver for generating and testing the parser for this grammar is the [tree-sitter CLI][cli].\nOther components of the project require additional tools, described below.\n\nSome are made available through `npm` – for example, `npx tree-sitter` runs the CLI.\nIf you don't have `tree-sitter` available otherwise, prefix all the commands in the following sections with `npx`.\n\n## Output path\n\nThe CLI writes the shared library containing the parser to the directory denoted by `$TREE_SITTER_LIBDIR`.\nIf that variable is unset, it defaults to `$HOME/.cache/tree-sitter/lib`.\n\nIn order to avoid clobbering this global directory with development versions, you can set the env var to a local path:\n\n```\nexport TREE_SITTER_LIBDIR=$PWD/.lib\n```\n\n## The grammar\n\nThe javascript file `grammar.js` contains the entry point into the grammar's production rules.\nPlease consult the [tree-sitter documentation][grammar-docs] for a comprehensive introduction to the syntax and\nsemantics.\n\nParsing starts with the first item in the `rules` field:\n\n```javascript\n{\n rules: {\n haskell: $ => seq(\n optional($.header),\n optional($._body),\n ),\n }\n}\n```\n\n## Generating the parser\n\nThe first step in the development workflow converts the javascript rule definitions to C code in `src/parser.c`:\n\n```\n$ tree-sitter generate\n```\n\nTwo byproducts of this process are written to `src/grammar.json` and `src/node-types.json`.\n\n## Compiling the parser\n\nThe C code is automatically compiled by most of the test tools mentioned below, but you can instruct tree-sitter to do\nit in one go:\n\n```\n$ tree-sitter generate --build\n```\n\nIf you've set `$TREE_SITTER_LIBDIR` as mentioned above, the shared object will be written to `$PWD/.lib/haskell.so`.\n\nAside from the generated `src/parser.c`, tree-sitter will also compile and link `src/scanner.c` into this object.\nThis file contains the _external scanner_, which is a custom extension of the built-in lexer whose purpose is to handle\nlanguage constructs that cannot be expressed (efficiently) in the javascript grammar, like Haskell layouts.\n\n### WebAssembly\n\nThe parser can be compiled to WebAssembly as well, which requires `emscripten`:\n\n```\n$ tree-sitter build --wasm\n```\n\nThe resulting binary is written to `$PWD/tree-sitter-haskell.wasm`.\n\n## Testing the parser\n\nThe most fundamental test infrastructure for tree-sitter grammars consists of a set of code snippets with associated\nreference ASTs stored in `./test/corpus/*.txt`.\n\n```\n$ tree-sitter test\n```\n\nIndividual tests can be run by specifying (a substring of) their description with `-f`:\n\n```\n$ tree-sitter test -f 'module: exports empty'\n```\n\nThe project contains several other types of tests:\n\n- `test/parse/run.bash [update] [test names ...]` parses the files in `test/parse/*.hs` and compares the output with\n `test/parse/*.target`.\n If `update` is specified as the first argument, it will update the `.target` file for the first failing test.\n\n- `test/query/run.bash [update] [test names ...]` parses the files in `test/query/*.hs`, applies the queries in\n `test/query/*.query` and compares the output with `test/query/*.target`, similar to `test/parse`.\n\n- `test/rust/parse-test.rs` contains a few tests that use tree-sitter's Rust API to extract the test ranges for\n terminals in a slightly more convenient way.\n This requires `cargo` to be installed, and can be executed with `cargo test` (which also runs the tests in\n `bindings/rust`).\n\n- `test/parse-libs [wasm]` clones a set of Haskell libraries to `test/libs` and parses the entire codebase.\n When invoked as `test/parse-libs wasm`, it will use the WebAssembly parser.\n This requires `bc` to be installed.\n\n- `test/parse-lib name [wasm]` parses only the library `name` in that directory (without cloning the repository).\n\n### Debugging\n\nThe shared library built by `tree-sitter test` includes debug symbols, so if the scanner segfaults you can just run\n`coredumpctl debug` to inspect the backtrace and memory:\n\n```\nnewline_lookahead () at src/scanner.c:2583\n2583 ((Newline *) 0)->indent = 5;\n(gdb) bt\n#0 newline_lookahead () at src/scanner.c:2583\n#1 0x00007ffff7a0740e in newline_start () at src/scanner.c:2604\n#2 scan () at src/scanner.c:2646\n#3 eval () at src/scanner.c:2684\n#4 tree_sitter_haskell_external_scanner_scan (payload=, lexer=,\n valid_symbols=) at src/scanner.c:2724\n#5 0x0000555555772488 in ts_parser.lex ()\n```\n\nFor more control, launch `gdb tree-sitter` and start the process with `run test -f 'some test'`, and set a breakpoint\nwith `break tree_sitter_haskell_external_scanner_scan`.\n\nTo disable optimizations, run `tree-sitter test --debug-build`.\n\n#### Tracing\n\nThe `test` and `parse` commands offer two modes for obtaining detailed information about the parsing process.\n\nWith `tree-sitter test --debug`, every lexer step and shift/reduce action is printed to stderr.\n\nWith `tree-sitter test --debug-graph`, the CLI will generate an HTML file showing a graph representation of every step.\nThis requires `graphviz` to be installed.\n\n[tree-sitter]: https://github.com/tree-sitter/tree-sitter\n[ref]: https://www.haskell.org/onlinereport/haskell2010/haskellch10.html\n[ext]:

parser executes the scanner.\n * Since several symbols are present both here and in `extras`, the scanner will be invoked before every single\n * natively lexed symbol, repeatedly, until it fails.\n * This makes indentation/layout tracking simpler.\n *\n * There are three special behavioral classes of symbols in this grammar, indicated by their name prefix:\n *\n * `cmd`: Commands are sequenced after key tokens like opening braces that unconditionally trigger a state change in\n * the scanner.\n * They don't require the scanner to _decide_ that a symbol is valid – the native parser has already committed\n * to a symbol, and the command relays that information to the scanner so it can update its state and return.\n * For example, after having parsed an opening brace, the scanner adds a brace context to the stack in reaction\n * to `_cond_brace_open`, which will influence its future behavior.\n * These symbols do not produce nodes in the parse tree.\n *\n * `cond`: Conditions are hard requirements in the grammar that are decided by the scanner based on its state and the\n * lookahead.\n * For example, whitespace-sensitive operators (tight infix /prefix ops) like the `@` in a type application or\n * the `.` in a record projection are lexed when the following characters have certain properties.\n * When the scanner decides that such a symbol is valid, the parser cannot attempt to use an alternative\n * interpretation like it can with conflicts.\n * This is often difficult, but also especially useful to force declarations and other layout items to be\n * terminated when a new line has smaller or equal indent, preventing incorrect interpretations as top level\n * expression splices spanning multiple lines.\n *\n * `phantom`: Phantom symbols are used to signal to the scanner that certain constructs are valid without requiring\n * the scanner to actually parse them and produce text nodes for them.\n * In the grammar, they are always optional, and the scanner never emits the phantom symbol itself, but\n * decides whether to emit _other_ symbols when the phantom symbol is _not_ valid.\n * This is used to implement GHC's tactic of allowing layouts to end _whenever a parse error occurs_, but\n * using specialized heuristics.\n *\n * Most other symbols produce nodes, except for newline and the error sentinel.\n */\n externals: $ => [\n\n // This is an

sensitive and uses parse errors to end layouts, this component has many\n * responsibilities.\n *\n * tree-sitter runs the scanner at every position repeatedly until it fails, after which the built-in lexer consumes one\n * token.\n * When the scanner succeeds, it returns the index of a symbol in the `externals` array in `grammar/externals.js`, which\n * is then processed like other grammar symbols, except that it terminates any conflict branches in which the symbol\n * isn't valid.\n * The scanner's state is persisted and passed into the next run, but it is discarded when the scanner fails, i.e. when\n * it yields control back to the built-in lexer.\n *\n * The high-level workflow of the scanner consists of three distinct modes.\n * When the first character after whitespace is a newline, the scanner starts newline lookahead, otherwise it processes\n * an interior position.\n * If the state indicates that the previous run performed newline lookahead, it enters newline processing mode.\n *\n * In interior mode, a single lexing pass is performed.\n *\n * Such a pass consists of two steps:\n *\n * In the first step, the scanner identifies the immediate token by branching on the first character after whitespace\n * and examining different conditions to select one of the variants of the enum `Lexed`, which enumerates all known,\n * interesting, situations.\n * The position of the lexer may be advanced in the process to look at subsequent characters.\n * To avoid having to arrange different parts of the logic according to how many characters have been consumed,\n * lookahead is written to an array in the transient state on demand, so that each component can specify the index\n * relative to the position at the beginning of the run (modulo whitespace).\n * The entry point for this step is the function `lex`.\n *\n * The second step is different for each mode.\n * In interior mode, the `Lexed` token determines which symbol to return to the grammar based on the current state, like\n * layout contexts and valid symbols.\n * Most symbols do not contain any text, but only act as conditions in the grammar, but for symbolic operators, CPP,\n * comments, pragmas, and quasiquotes, the lexer is advanced to the end of the token and `mark_end` is called to\n * communicate the range to tree-sitter.\n *\n * In newline lookahead mode, the scanner performs repeated lexing passes until it encounters a `Lexed` token that is\n * not CPP or a comment.\n * In the second step of each pass, the token determines whether to terminate and/or which flags to set in the state to\n * guide processing in the next run.\n * If the lookahead loop has only made a single lexing pass that did not consume any characters of the following token\n * (because the first character did not match any of the conditions for lexing that require more lookahead), the scanner\n * switches to newline processing mode directly; otherwise it terminates the run after storing the newline information\n * in the persistent state.\n * This is possible by succeeding with the symbol `UPDATE`, which is mapped to newline in `externals`.\n * tree-sitter does not create a node in the parse tree for this symbol if `mark_end` wasn't called after consuming\n * lookahead, and immediately calls the scanner again at the same position.\n *\n * In either case, the scanner ends up in newline processing mode, in which it performs a series of highly\n * order-sensitive steps based on the data collected in lookahead mode, potentially returning multiple symbols in\n * successive runs until none of the newline-related conditions match.\n * This procedure ensures that nested layouts are terminated at the earliest position instead of extending over all\n * subsequent (top-level) whitespace, comments and CPP up to the next layout element.\n * Only when all layouts are terminated will the scanner process the final `Lexed` token that it stored in the state in\n * lookahead mode, using the same logic as in interior mode, and update the state to disable newline processing for the\n * next run.\n */\n\n#include \"tree_sitter/alloc.h\"\n#include

character is appended to this vector.\n * This avoids having to ensure that different components that need to examine multiple lookahead characters have to be\n * run in the correct order.\n * Instead, we refer to lookahead by the character's index using the interface described in the section 'Lookahead'.\n *\n * For example, the functions `peek0`, `char0`, `char1` operate on the first/second character relative to the start of\n * the scanner run, and the implementation advances the lexer position when it is necessary.\n *\n * The field `offset` can be used to reset relative indexing to the current lexer position.\n * This is used, for example, in `newline_lookahead`, to perform repeated lexing passes, since `lex` uses the lookahead\n * interface.\n * After processing a `Lexed` token, `newline_lookahead` continues seeking ahead after comments and CPP, and when it\n * encounters the next token, it calls `reset_lookahead` to set `offset` to the current position, ensuring that `lex`\n * can use `char0` to test the following character.\n *\n * The terminology for advancing is:\n * - \"Advance before character C at index N\" means \"`lexer->lookahead` returns C, but 'Lookahead' does not contain C and\n * has size N\"\n * - \"Advance over character C at index N\" means \"`lexer->lookahead` returns the character following C, 'Lookahead'\n * contains C and has size N+1\" (or \"advance before N+1\")\n * - If the size of 'Lookahead' is already larger than N, and therefore C can be read from the vector, the\n * postconditions may not hold (when independent steps access lookahead at different indexes)\n *\n * Example:\n *\n * Assume we are parsing the following line, and the scanner is called right after the `a` in the right-hand side:\n *\n * > calc a b = a Library.Math.** b\n * ^ (lexer position: before the character above the ^, `lexer->lookahead` returns the space)\n * || 0/0 (content of `data` between bars, empty; `len` after bars, `offset` after slash)\n *\n * 'Lookahead' is initialized with `len = 0` and `offset = 0`.\n *\n * The full lookahead string (stored in tree-sitter's internals) at this position is ` Library.Math.** b`, and all\n * _absolute_ indexes point into that string.\n * Since tree-sitter only exposes the \"next\" character at a time, indexing requires advancing the lexer and copying\n * characters to 'Lookahead' on demand.\n *\n * An initial `skip_space` advances over the space between `a` and `Lib`, which does not update 'Lookahead'.\n *\n * > calc a b = a Library.Math.** b\n * ^\n * || 0/0\n *\n * The uppercase character in `Lib` triggers the detection of qualified operators in `qualified_op`, which repeatedly\n * lexes module segments and dots.\n *\n * The module segment step starts (in `conid`) by checking that the next character is upper case using `peek0` (short\n * for `peek(0)`), which accesses the _first_ lookahead character – but _first_ is always relative to the current\n * `offset`.\n * We call the relative index `rel` and the absolute one `abs = offset + rel`.\n * Before `Lib`, this translates to `abs = rel = 0`.\n *\n * `peek` checks if 'Lookahead' already contains the character for this index (`abs < len`), so it can directly return\n * the value at `data[abs]`, which fails, since the vector is empty.\n * Instead, it will fetch the character directly from the tree-sitter lexer.\n * The lexer provides one character of lookahead outside of 'Lookahead', which is enough for this case.\n * `peek` is a conservative action, so it will not copy the character to 'Lookahead', and leave the lexer position\n * unchanged.\n *\n * `L` is upper case, so `qualified_op` switches to the next phase: Advancing to the end of the module segment, which\n * amounts to advancing before the first character that is not an identifier character:\n *\n * > advance_while(1, is_inner_id_char)\n *\n * This function applies the specified predicate to the character at the specified index.\n * If that returns `true`, it advances over the character and increments the index.\n * These steps are repeated until the predicate is `false`.\n * The index is returned, pointing to the character after the module segment.\n *\n * `peek0` doesn't modify lookahead, so the next character is still `L`.\n * We don't need to validate it again, so the starting index specified to `advance_while` is `1`.\n *\n * Let's look at the steps performed by this function in detail.\n * It starts by accessing the character at the initial index, calling `peek(1)`.\n * As for the `L` check, this calculates `abs = offset + rel = 0 + 1` and determines that it is smaller than `len`,\n * again.\n * However, this time the requested character is the _second_ lookahead character, so `peek` calls `advance_before(1)`,\n * which calls `advance` as many times as needed to access the character via `lexer->lookahead`, which is\n * `offset + n - len` times, so _once_ in this case.\n * The result is that `L` is copied to 'Lookahead' and `lexer->advance` is invoked one time, resulting in this new\n * state:\n *\n * > calc a b = a Library.Math.** b\n * ^\n * || 1/0\n *\n * Now `lexer->lookahead` returns `i`, which `conid` successfully validates as an \"inner ID character\", so it increments\n * the index to 2.\n * `peek(2)` performs the exact same steps as `peek(1)`, as do all subsequent steps until `peek(7)` returns `.`, which\n * fails the predicate, terminating the loop without advancing and returning 7 from `conid`, with the final state:\n *\n * > calc a b = a Library.Math.** b\n * ^\n * || 7/0\n *\n * `qualified_op` now examines the returned index:\n * If it is 0, the first character was not upper case and there is no module segment at this position, so lexing fails\n * and the scanner returns control to tree-sitter.\n * Otherwise, it calls `char_at(7, '.')` to require that the character after the module segment is a dot, with the same\n * consequences.\n *\n * Since our test code meets these conditions, `qualified_op` continues with `reset_lookahead_to(8)`.\n * This sets `offset` to 8, causing all future lookahead actions that use relative indexes to operate on characters\n * _after_ this new offset.\n * Here this is the first character after the dot, `M`.\n * Note that modifying the offset does not advance the lexer right away, so the lexer position will remain at 7:\n *\n * > calc a b = a Library.Math.** b\n * ^ (zero-based index 7)\n * || 7/8\n *\n * After a dot, `qualified_op` decides what to do next by determining whether what follows is a symbolic operator by\n * calling `symop_lookahead`, which uses the same predicate-based function as before, `advance_while(0, symop_char)`.\n * When that function calls `peek(0)`, the absolute index `offset + 0 = 8` is requested, which is not available, so the\n * lexer is advanced once:\n *\n * > calc a b = a Library.Math.** b\n * ^\n * || 8/8\n *\n * Note that `len == 8` means there are eight characters in 'Lookahead', up to and including the dot, while the index\n * `offset == 8` refers to the _ninth_ character, `M`.\n *\n * `M` is not a symop character, so `qualified_op` restarts the loop and parses the next module segment.\n * The process is identical to the previous iteration except for the value of `offset`, which causes all steps that\n * examine relative lookahead with `peek0` and `peek_at` add 8 to each index.\n *\n * Once the second dot is parsed, the symop test will succeed after advancing over both asterisks, which satisfies the\n * termination condition in `qualified_op`, and the scanner run finishes with the final state:\n *\n * > calc a b = a Library.Math.** b\n * ^\n * || 15/13\n */\ntypedef struct {\n int32_t *contents;\n

matching the condition, where we unset the flag to avoid a mid-line semicolon from influencing\n * an unrelated newline.\n *\n * Take this example:\n *\n * > a = 1;;\n * > b = 2\n * > ;;c = 3\n *\n * At the first semicolon, `explicit_semicolon` is called (conditioned on `LSemi` in `process_token_interior`) and\n * SEMICOLON is valid, so the flag is set.\n * The scanner will be called again immediately without advancing, and first enter `resolve_semicolon`, which does\n * nothing because the next token is still `LSemi`.\n * Next it will enter `explicit_semicolon` again.\n * SEMICOLON is valid, but since the flag is set we fall through and defer to internal lexing.\n * The grammar advances into `semi` (in `util.js`), which causes SEMICOLON to become invalid.\n * The scanner is executed before the second semicolon, where both functions skip again, this time additionally because\n * SEMICOLON is now invalid.\n *\n * In the next scan, the newline branch is taken in `scan`, so this function is not executed again.\n * Newline lookahead finds the next line to begin at column 0, which would usually trigger a layout semicolon in\n * `semicolon`, but that is inhibited by `skip_semi`, so the scan only skips whitespace and resets the newline state,\n * which unsets `skip_semi` again.\n * In the following scan, the conditions for both functions are unfulfilled, so parsing continues regularly until the\n * next newline.\n *\n * Newline lookahead now encounters the third semicolon on the next line and sets `no_semi`, which supersedes\n * `skip_semi` and prohibits layout semicolon irreversibly, so the explicit semicolons are parsed by the grammar.\n *\n * Now consider an inline semicolon:\n *\n * > f = let\n * > a = 1; b = 2\n * > c = 3; {- x -}\n * > d = 4\n * > in c\n *\n * When the semicolon is lexed, `explicit_semicolon` sets `skip_semi`.\n * If we would not reset it until the newline, no layout semicolon would be generated before `c`, resulting in a parse\n * error at `=`.\n * Therefore, `resolve_semicolon` unsets `skip_semi` when lexing `b`, triggered by `skip_semi` being set and the next\n * token not being `LSemi`.\n *\n * The semicolon after `c = 3` is followed by a comment, so it is unclear if there is going to be another layout element\n * in the same line.\n * If there is none, the situation is the same as in the first example's first line; if another layout element were to\n * follow, `skip_semi` would need to be reset like in this example's first line.\n * Therefore, `resolve_semicolon` also keeps the flag as it is in this

this situation:\n *\n * > data A = B b % C => D d :+ E\n * > data E = F f => G g\n *\n * After the `=`, a diverse set of constructs are valid.\n *\n * - Data constructor\n * - Infix `D d :+ E` -> `(type/name) (type/variable) (constructor_operator) (type/name)`\n * - Prefix `G g` -> `(name) (type/variable)`\n * - Context\n * - Infix `B b % C` -> `(type/name) (type/variable) (operator) (type/name)`\n * - Prefix `F f` -> `(constraint/name) (type/variable)`\n *\n * Each of these starts with a `(name)` with different reduction rules that can only be resolved when the arrow or a\n * data constructor-ending token is encountered.\n * The conflict between `D` and `G` is an additional hurdle that is not addressed here.\n *\n * Constraint lookahead scans ahead until it finds `=>` or a clear rejection criterion like `=` or (layout) semicolon,\n * emitting `_cond_context` to unlock the rules `_qtype_context`, `context` and `_ctr_context`.\n *\n * However, even the two context variants conflict, since infix classes have types in their operands, while a prefix\n * constraint starts with a class name.\n * To mitigate this, constraint lookahead additionally emits `_cond_infix` when it encounters an infix operator.\n * This symbol is only emitted when `_cond_context` is not valid (because it was parsed right before) or because no `=>`\n * is encountered afterwards (because the current position is in parentheses).\n * This only works because infix classes are localized within contexts – disambiguating all infix types like this is\n * impossible without completely restructuring the grammar.\n *\n * Note that this problem could easily be avoided by parsing all contexts as types, accepting that queries for class\n * names would be more verbose and couldn't match more complex constraints.\n * Furthermore, a much simpler fix would be a runtime conflict, which has the potential to result in randomly incorrect\n * parse trees.\n *\n * Similarly to contexts, data constructor heads have infix type-related conflicts that aren't as severe but can easily\n * piggyback on this mechanism, so they are included.\n *\n * Lastly, associated type families and instances conflict because they can both be heralded by `type` alone, so the\n * decision to reduce to type head or instance head nodes is informed by the presence of `::` or `=` without `|`.\n */\n\n/**\n *
