README#tonyfettes/tree_sitter
This is a MoonBit binding to the
tree-sitter incremental
parsing library.
#Quickstart
- Add this module as a dependency to your MoonBit project:moon update # Update the mooncakes.io package index moon add tonyfettes/tree_sitter
- Import the tonyfettes/tree_sitter package in moon.pkg.json:{ "import": [ "tonyfettes/tree_sitter" ] }
- Optionally you may want to install MoonBit bindings to the tree-sitter
grammars you want to use. For example, to install the tree-sitter-moonbit
grammar:
And then import the tonyfettes/tree_sitter_moonbit package in your moon.pkg.json file as well:moon add tonyfettes/tree_sitter_moonbit{ "import": [ "tonyfettes/tree_sitter", "tonyfettes/tree_sitter_moonbit" ] } - Use the tonyfettes/tree_sitter API to parse your code:fn main {
let moonbit = @tree_sitter_moonbit.language()
let parser = @tree_sitter.Parser::new()
parser.set_language(moonbit)
let source_code =
#|fn main {
#| println("Hello, World!")
#|}
let tree = parser.parse_string(None, source_code)
let root_node = tree.root_node()
println(root_node.string())
}
#API Walkthrough
The Tree-sitter User Guide is a
good place to start if you're new to tree-sitter. Although the API is written in
C, this MoonBit binding is just a thin wrapper around the C API, so the
documentation should be mostly applicable.
This binding is at its very early stages, so many APIs are not yet implemented.
If you find a missing API that you need, please open an issue or a pull request.
Apart from the standard tree-sitter API, this binding also provides
abilities to parse the grammar.json and node-types.json files that are
generated by the tree-sitter CLI. This is useful if you want to generate
MoonBit type definitions for a tree-sitter grammar.
#Development
#Prerequisites
Other than MoonBit toolchain, this project requires Python (3.9 or later) to
build. Please make sure your system has python available in the PATH.
#Build
The build should work out of the box on Linux and macOS. Windows is not tested,
and you are more than welcome to open an issue or a pull request if you find
problems.
# Initialize the tree-sitter submodule
git submodule update --init --recursive
moon update
moon build --target nativeWe amalgamate the tree-sitter source code with the C stubs together to build a
monolithic C file (src/tree-sitter-lib/lib.c) that can be compiled as a single
object file. This step is done by a Python script at scripts/prepare.py. The
script is set to run automatically when you run moon build --target native or
moon check --target native. If you find the generated C file is out of date,
you can run the script manually:
python scripts/prepare.py#Test
Before running tests, make sure you have completed the build step above.
To avoid introducing the dependency of the tree-sitter grammars, we put the
majority of the tests inside the test/ directory. To run the tests, you can
cd into the test/ directory and run moon test --target native:
cd test && moon test --target native[!NOTE] You may find that the LSP is not working when you are editing files under the test/ directory. This is because test/ is a MoonBit module itself, and therefore the LSP process has to be spawned in the test/ directory to work properly. In most cases, this means you need to spin up a new editor instance inside the test/ directory.
#QueryPredicate
An Array is a collection of values that supports random access and can
grow in size.
#DecodeFunction
pub(open) trait DecodeFunction {
encoding(Self) -> InputEncoding = _
decode(BytesView) -> DecodeResult?
}This function signature reads one code point from the given bytes,
returning the number of bytes consumed and the code point.
If the input is invalid, return None.
#DecodeResult
type DecodeResult#Input
type Input[DecodeFunction]#InputEdit

#Language
#Language::abi_version
Get the ABI version number for this language. This version number is used
to ensure that languages were generated by a compatible version of
Tree-sitter.
See also Parser::set_language.
#Language::copy
Get another reference to the given language.
#Language::delete
Free any dynamically-allocated resources for this language, if
this is the last reference.
#Language::field_count
Get the number of distinct field names in the language.
#Language::field_id_for_name
Get the numerical id for the given field name string.
#Language::field_name_for_id
Get the field name string for the given numerical id.
#Language::inner
Convert newtype to its underlying type, automatically derived.
#Language::metadata
Get the metadata for this language. This information is generated by the
CLI, and relies on the language author providing the correct metadata in
the language's tree-sitter.json file.
See also LanguageMetadata.
#Language::name
Get the name of this language. This returns None in older parsers.
#Language::next_state
Get the next parse state. Combine this with lookahead iterators to generate
completion suggestions or valid symbols in error nodes. Use
Node::grammar_symbol for valid symbols.
#Language::state_count
Get the number of valid states in this language.
#Language::subtypes
Get a list of all subtype symbol ids for a given supertype symbol.
See Language::supertypes for fetching all supertype symbols.
#Language::supertypes
Get a list of all supertype symbols for the language.
#Language::symbol_count
Get the number of distinct node types in the language.
#Language::symbol_for_name
Get the numerical id for the given node type string.
#Language::symbol_name
Get a node type string for the given numerical id.
#Language::symbol_type
Check whether the given node type id belongs to named nodes, anonymous nodes,
or a hidden nodes.
See also Node::is_named. Hidden nodes are never returned from the API.
#Language::version
Get the ABI version number for this language. This version number is used
to ensure that languages were generated by a compatible version of
Tree-sitter.
See also Parser::set_language.
#LanguageMetadata
type LanguageMetadataThe metadata associated with a language.
Currently, this metadata can be used to check the Semantic Version
of the language. This version information should be used to signal if a given parser might
be incompatible with existing queries when upgrading between major versions, or minor versions
if it's in zerover.
#LanguageMetadata::major_version
#LanguageMetadata::minor_version
#LanguageMetadata::patch_version
#Logger
type Logger#LookaheadIterator
type LookaheadIterator#LookaheadIterator::current_symbol
Get the current symbol of the lookahead iterator.
#LookaheadIterator::current_symbol_name
Get the current symbol type of the lookahead iterator as a string.
#LookaheadIterator::language
Get the current language of the lookahead iterator.
#LookaheadIterator::new
Create a new lookahead iterator for the given language and parse state.
This returns None if state is invalid for the language.
Repeatedly using LookaheadIterator::next and
LookaheadIterator::current_symbol will generate valid symbols in the
given parse state. Newly created lookahead iterators will contain the
ERROR symbol.
Lookahead iterators can be useful to generate suggestions and improve syntax
error diagnostics. To get symbols valid in an ERROR node, use the lookahead
iterator on its first leaf node state. For MISSING nodes, a lookahead
iterator created on the previous non-extra leaf node may be appropriate.
#LookaheadIterator::next
Advance the lookahead iterator to the next symbol.
This returns true if there is a new symbol and false otherwise.
#LookaheadIterator::reset
Reset the lookahead iterator.
This returns true if the language was set successfully and false
otherwise.
#LookaheadIterator::reset_state
Reset the lookahead iterator to another state.
This returns true if the iterator was reset to the given state and false
otherwise.
#Node
type Node#Node::child
Get the node's child at the given index, where zero represents the first
child.
#Node::child_by_field_id
Get the node's child with the given numerical field id.
You can convert a field name to an id using the
Language::field_id_for_name function.
#Node::child_by_field_name
Get the node's child with the given field name.
#Node::child_with_descendant
Get the node that contains descendant.
Note that this can return descendant itself.
#Node::descendant_count
Get the node's number of descendants, including one for the node itself.
#Node::descendant_for_byte_range
Get the smallest node within this node that spans the given range of bytes.
#Node::descendant_for_point_range
Get the smallest node within this node that spans the given range of
(row, column) positions.
#Node::edit
Edit the node to keep it in-sync with source code that has been edited.
This function is only rarely needed. When you edit a syntax tree with the
Tree::edit function, all of the nodes that you retrieve from the tree
afterward will already reflect the edit. You only need to use Node::edit
when you have a Node instance that you want to keep and continue to use
after an edit.
#Node::field_name_for_child
Get the field name for node's child at the given index, where zero represents
the first child. Returns None, if no field is found.
#Node::field_name_for_named_child
Get the field name for node's named child at the given index, where zero
represents the first named child. Returns None, if no field is found.
#Node::first_child_for_byte
Get the node's first child that contains or starts after the given byte offset.
#Node::first_named_child_for_byte
Get the node's first named child that contains or starts after the given byte offset.
#Node::grammar_symbol
Get the node's type as a numerical id as it appears in the grammar ignoring
aliases. This should be used in Language::next_state instead of
Node::symbol.
#Node::grammar_type
Get the node's type as it appears in the grammar ignoring aliases as a string.
#Node::has_changes
Check if a syntax node has been edited.
#Node::has_error
Check if the node is a syntax error or contains any syntax errors.
#Node::is_extra
Check if the node is extra. Extra nodes represent things like comments,
which are not required the grammar, but can appear anywhere.
#Node::is_missing
Check if the node is missing. Missing nodes are inserted by the parser in
order to recover from certain kinds of syntax errors.
#Node::is_named
Check if the node is named. Named nodes correspond to named rules in the
grammar, whereas anonymous nodes correspond to string literals in the
grammar.
#Node::is_null
Check if the node is null. Functions like Node::child and
Node::next_sibling will return a null node to indicate that no such node
was found.
#Node::named_child
Get the node's named child at the given index.
See also Node::is_named.
#Node::named_child_count
Get the node's number of named children.
See also Node::is_named.
#Node::named_children
Get all named children of the node.
#Node::named_descendant_for_byte_range
Get the smallest named node within this node that spans the given range of
bytes.
#Node::named_descendant_for_point_range
Get the smallest named node within this node that spans the given
(row, column) positions.
#Node::next_named_sibling
Get the node's next named sibling.
#Node::next_parse_state
Get the parse state after this node.
#Node::parent
Get the node's immediate parent.
Prefer Node::child_with_descendant for iterating over the node's ancestors.
#Node::prev_named_sibling
Get the node's previous named sibling.
#Node::prev_sibling
Get the node's previous sibling.
#Node::start_point
Get the node's start position in terms of rows and columns.
#Node::string
Get an S-expression representing the node as a string.
#ParseOptions
type ParseOptionsOptions for parsing.
#ParseOptions::new
Create new parse options with the given progress callback.
#ParseState
pub struct ParseState {
current_byte_offset : Int
has_error : Bool
}The state of a parse operation.
#Parser
type Parser#Parser::included_ranges
Get the ranges of text that the parser will include when parsing.
#Parser::language
Get the parser's current language.
#Parser::parse
fn[Encoding : DecodeFunction] Parser::parse(self : Parser, old_tree? : Tree, input : Input[Encoding], options? : ParseOptions) -> Tree raise ParseErrorUse the parser to parse some source code and create a syntax tree.
If you are parsing this document for the first time, pass None for the
old_tree parameter. Otherwise, if you have already parsed an earlier
version of this document and the document has since been edited, pass the
previous syntax tree so that the unchanged parts of it can be reused.
This will save time and memory. For this to work correctly, you must have
already edited the old syntax tree using the Tree::edit function in a
way that exactly matches the source code changes.
The Input parameter lets you specify how to read the text. It has the
following fields:
- read: A function to retrieve a chunk of text at a given byte offset and (row, column) position. The function should return a pointer to the text and write its length to the bytes_read pointer. The parser does not take ownership of this buffer; it just borrows it until it has finished reading it. The function should write a zero value to the bytes_read pointer to indicate the end of the document.
- decode: A function to decode the text. This is only used if the encoding is Custom. Additionally, you can pass InputEncoding::UTF8 or InputEncoding::UTF16 to the Input parameter to specify the encoding of the text.
This function returns a syntax tree on success, and None on failure. There
are four possible reasons for failure:
- The parser does not have a language assigned. Check for this using the Parser::language function.
- Parsing was cancelled due to a timeout that was set by an earlier call to the Parser::set_timeout_micros function. You can resume parsing from where the parser left out by calling Parser::parse again with the same arguments. Or you can start parsing from scratch by first calling Parser::reset.
- Parsing was cancelled using a cancellation flag that was set by an earlier call to Parser::set_cancellation_flag. You can resume parsing from where the parser left out by calling Parser::parse again with the same arguments.
- Parsing was cancelled due to the progress callback returning true. This callback is passed as the options argument inside the ParseOptions struct.
#Parser::parse_bytes
fn Parser::parse_bytes(self : Parser, old_tree? : Tree, bytes : Bytes, encoding~ : InputEncoding) -> Tree raise ParseErrorUse the parser to parse some source code stored in one contiguous buffer
with a given encoding. The first three parameters work the same as in the
parse method. The final parameter indicates whether the text is encoded as
UTF8 or UTF16.
#Parser::parse_string
fn Parser::parse_string(self : Parser, old_tree? : Tree, string : StringView) -> Tree raise ParseErrorUse the parser to parse some source code stored in one contiguous string buffer.
The first two parameters are the same as in the parse function. The final
parameter is the string to parse.
#Parser::reset
Instruct the parser to start the next parse from the beginning.
If the parser previously failed because of a timeout or a cancellation, then
by default, it will resume where it left off on the next call to
parse or other parsing functions. If you don't want to resume,
and instead intend to use this parser to parse some other document, you must
call reset first.
#Parser::set_included_ranges
Set the ranges of text that the parser should include when parsing.
By default, the parser will always include entire documents. This function
allows you to parse only a portion of a document but still return a syntax
tree whose ranges match up with the document as a whole. You can also pass
multiple disjoint ranges.
The second and third parameters specify the location and length of an array
of ranges.
If count is zero, then the entire document will be parsed. Otherwise,
the given ranges must be ordered from earliest to latest in the document,
and they must not overlap. That is, the following must hold for all:
i < count - 1: ranges[i].end_byte <= ranges[i + 1].start_byte
If this requirement is not satisfied, the operation will fail, the ranges
will not be assigned, and this function will return false. On success,
this function returns true
#Parser::set_language
Set the language that the parser should use for parsing.
Returns a boolean indicating whether or not the language was successfully
assigned. True means assignment succeeded. False means there was a version
mismatch: the language was generated with an incompatible version of the
Tree-sitter CLI. Check the language's ABI version using
Language::abi_version and compare it to this library's LANGUAGE_VERSION
and MIN_COMPATIBLE_LANGUAGE_VERSION constants.
#Parser::set_logger
Set the logger that a parser should use during parsing.
The parser does not take ownership over the logger payload. If a logger was
previously assigned, the caller is responsible for releasing any memory
owned by the previous logger.
#Point
type Point#Query
type Query#Query::capture_count
Get the number of captures in the query.
#Query::capture_name_for_id
Get the name of one of the query's captures. Each capture is associated with a
numeric id based on the order that it appeared in the query's source.
#Query::capture_quantifier_for_id
fn Query::capture_quantifier_for_id(self : Query, pattern_index : Int, capture_index : Int) -> QuantifierGet the quantifier of the query's captures. Each capture is
associated with a numeric id based on the order that it appeared in the query's source.
#Query::disable_capture
Disable a certain capture within a query.
This prevents the capture from being returned in matches, and also avoids
any resource usage associated with recording the capture. Currently, there
is no way to undo this.
#Query::disable_pattern
Disable a certain pattern within a query.
This prevents the pattern from matching and removes most of the overhead
associated with the pattern. Currently, there is no way to undo this.
#Query::end_byte_for_pattern
Get the byte offset where the given pattern ends in the query's source.
This can be useful when combining queries by concatenating their source
code strings.
#Query::is_pattern_guaranteed_at_step
Check if a given pattern is guaranteed to match once a given step is reached.
The step is specified by its byte offset in the query's source code.
#Query::is_pattern_non_local
Check if the given pattern in the query is 'non local'.
A non-local pattern has multiple root nodes and can match within a
repeating sequence of nodes, as specified by the grammar. Non-local
patterns disable certain optimizations that would otherwise be possible
when executing a query on a specific range of a syntax tree.
#Query::is_pattern_rooted
Check if the given pattern in the query has a single root node.
#Query::new
Create a new query from a string containing one or more S-expression
patterns. The query is associated with a particular language, and can
only be run on syntax nodes parsed with that language.
If all of the given patterns are valid, this returns a Query.
If a pattern is invalid, this raises a QueryError.
#Query::pattern_count
Get the number of patterns in the query.
#Query::predicates_for_pattern
fn Query::predicates_for_pattern(self : Query, pattern_index : Int) -> Array[Array[QueryPredicateStep]]Get all of the predicates for the given pattern in the query.
The predicates are represented as a single array of array of steps.
There are two types of steps in this array:
- QueryPredicateStep::Capture - Steps with this type represent names of captures. Their value_id can be used with the Query::capture_name_for_id function to obtain the name of the capture.
- QueryPredicateStep::String - Steps with this type represent literal strings. Their value_id can be used with the Query::string_value_for_id function to obtain their string value.
#Query::start_byte_for_pattern
Get the byte offset where the given pattern starts in the query's source.
This can be useful when combining queries by concatenating their source
code strings.
#Query::string_count
Get the number of string literals in the query.
#QueryCursor
type QueryCursor#QueryCursor::did_exceed_match_limit
Check if the query cursor exceeded its match limit.
Query cursors have an optional maximum capacity for storing lists of
in-progress captures. If this capacity is exceeded, then the
earliest-starting match will silently be dropped to make room for further
matches. This maximum capacity is optional — by default, query cursors allow
any number of pending matches, dynamically allocating new space for them as
needed as the query is executed.
#QueryCursor::exec
fn QueryCursor::exec(self : QueryCursor, query : Query, node : Node, options? : QueryCursorOptions) -> UnitStart running a given query on a given node, with optional options.
#QueryCursor::match_limit
Get the maximum number of in-progress matches allowed by this query cursor.
See QueryCursor::did_exceed_match_limit.
#QueryCursor::new
Create a new cursor for executing a given query.
The cursor stores the state that is needed to iteratively search for
matches. To use the query cursor, first call QueryCursor::exec
to start running a given query on a given syntax node. Then, there are
two options for consuming the results of the query:
- Repeatedly call QueryCursor::next_match to iterate over all of the matches in the order that they were found. Each match contains the index of the pattern that matched, and an array of captures. Because multiple patterns can match the same set of nodes, one match may contain captures that appear before some of the captures from a previous match.
- Repeatedly call QueryCursor::next_capture to iterate over all of the individual captures in the order that they appear. This is useful if don't care about which pattern matched, and just want a single ordered sequence of captures.
If you don't care about consuming all of the results, you can stop calling
QueryCursor::next_match or QueryCursor::next_capture at any point.
You can then start executing another query on another node by calling
QueryCursor::exec again.
#QueryCursor::next_capture
Advance to the next capture of the currently running query.
If there is a capture, returns Some(capture).
Otherwise, returns None.
#QueryCursor::next_match
Advance to the next match of the currently running query.
If there is a match, returns Some(match).
Otherwise, returns None.
#QueryCursor::remove_match
Remove a match from the query cursor's results.
#QueryCursor::set_byte_range
Set the range of bytes in which the query will be executed.
The query cursor will return matches that intersect with the given byte range.
This means that a match may be returned even if some of its captures fall
outside the specified range, as long as at least part of the match
overlaps with the range.
#QueryCursor::set_match_limit
Set the maximum number of in-progress matches allowed by this query cursor.
See QueryCursor::did_exceed_match_limit.
#QueryCursor::set_max_start_depth
Set the maximum start depth for a query cursor.
This prevents cursors from exploring children nodes at a certain depth.
Note if a pattern includes many children, then they will still be checked.
The zero max start depth value can be used as a special behavior and
it helps to destructure a subtree by staying on a node and using captures
for interested parts. Note that the zero max start depth only limit a search
depth for a pattern's root node but other nodes that are parts of the pattern
may be searched at any depth what defined by the pattern structure.
Set to @uint.max_value to remove the maximum start depth.
#QueryCursor::set_point_range
Set the range of (row, column) positions in which the query will be executed.
The query cursor will return matches that intersect with the given point range.
This means that a match may be returned even if some of its captures fall
outside the specified range, as long as at least part of the match
overlaps with the range.
#QueryCursorOptions
type QueryCursorOptions#QueryCursorOptions::new
#QueryPredicateStep
pub enum QueryPredicateStep {
Capture(String)
String(String)
}#Range
type Range#Range::new
#SymbolType
pub enum SymbolType {
Regular
Anonymous
Supertype
Auxiliary
}Check whether the given node type id belongs to named nodes, anonymous nodes,
or a hidden nodes.
#Tree
type Tree#Tree::copy
Create a shallow copy of the syntax tree. This is very fast.
You need to copy a syntax tree in order to use it on more than one thread at
a time, as syntax trees are not thread safe.
#Tree::edit
Edit the syntax tree to keep it in sync with source code that has been
edited.
You must describe the edit both in terms of byte offsets and in terms of
(row, column) coordinates.
#Tree::get_changed_ranges
Compare an old edited syntax tree to a new syntax tree representing the same
document, returning an array of ranges whose syntactic structure has changed.
For this to work correctly, the old syntax tree must have been edited such
that its ranges match up to the new tree. Generally, you'll want to call
this function right after calling one of the Parser::parse functions.
You need to pass the old tree that was passed to parse, as well as the new
tree that was returned from that function.
The returned ranges indicate areas where the hierarchical structure of syntax
nodes (from root to leaf) has changed between the old and new trees. Characters
outside these ranges have identical ancestor nodes in both trees.
Note that the returned ranges may be slightly larger than the exact changed areas,
but Tree-sitter attempts to make them as small as possible.
#Tree::included_ranges
Get the array of included ranges that was used to parse the syntax tree.
#Tree::language
Get the language that was used to parse the syntax tree.
#Tree::root_node_with_offset
Get the root node of the syntax tree, but with its position
shifted forward by the given offset.
#TreeCursor
type TreeCursor#TreeCursor::current_depth
Get the depth of the cursor's current node relative to the original
node that the cursor was constructed with.
#TreeCursor::current_descendant_index
Get the index of the cursor's current node out of all of the
descendants of the original node that the cursor was constructed with.
#TreeCursor::current_field_id
Get the field id of the tree cursor's current node.
This returns zero if the current node doesn't have a field.
See also Node::child_by_field_id, Language::field_id_for_name.
#TreeCursor::current_field_name
Get the field name of the tree cursor's current node.
This returns None if the current node doesn't have a field.
See also Node::child_by_field_name.
#TreeCursor::current_node
Get the tree cursor's current node.
#TreeCursor::goto_descendant
Move the cursor to the node that is the nth descendant of
the original node that the cursor was constructed with, where
zero represents the original node itself.
#TreeCursor::goto_first_child
Move the cursor to the first child of its current node.
This returns true if the cursor successfully moved, and returns false
if there were no children.
#TreeCursor::goto_first_child_for_byte
Move the cursor to the first child of its current node that contains or starts after
the given byte offset.
This returns the index of the child node if one was found, and returns -1
if no such child was found.
#TreeCursor::goto_first_child_for_point
Move the cursor to the first child of its current node that contains or starts after
the given point.
This returns the index of the child node if one was found, and returns -1
if no such child was found.
#TreeCursor::goto_last_child
Move the cursor to the last child of its current node.
This returns true if the cursor successfully moved, and returns false if
there were no children.
Note that this function may be slower than TreeCursor::goto_first_child
because it needs to iterate through all the children to compute the child's
position.
#TreeCursor::goto_next_sibling
Move the cursor to the next sibling of its current node.
This returns true if the cursor successfully moved, and returns false
if there was no next sibling node.
Note that the node the cursor was constructed with is considered the root
of the cursor, and the cursor cannot walk outside this node.
#TreeCursor::goto_parent
Move the cursor to the parent of its current node.
This returns true if the cursor successfully moved, and returns false
if there was no parent node (the cursor was already on the root node).
Note that the node the cursor was constructed with is considered the root
of the cursor, and the cursor cannot walk outside this node.
#TreeCursor::goto_previous_sibling
Move the cursor to the previous sibling of its current node.
This returns true if the cursor successfully moved, and returns false if
there was no previous sibling node.
Note, that this function may be slower than TreeCursor::goto_next_sibling
due to how node positions are stored. In the worst case, this will need to
iterate through all the children up to the previous sibling node to recalculate
its position. Also note that the node the cursor was constructed with is
considered the root of the cursor, and the cursor cannot walk outside this node.
#TreeCursor::new
Create a new tree cursor starting from the given node.
A tree cursor allows you to walk a syntax tree more efficiently than is
possible using the Node functions. It is a mutable object that is always
on a certain syntax node, and can be moved imperatively to different nodes.
Note that the given node is considered the root of the cursor,
and the cursor cannot walk outside this node.
#TreeCursor::reset
Re-initialize a tree cursor to start at the original node that the cursor was
constructed with.
#TreeCursor::reset_to
Re-initialize a tree cursor to the same position as another cursor.
Unlike TreeCursor::reset, this will not lose parent information and
allows reusing already created cursors.
#LANGUAGE_VERSION
let LANGUAGE_VERSION : IntThe latest ABI version that is supported by the current version of the
library. When Languages are generated by the Tree-sitter CLI, they are
assigned an ABI version number that corresponds to the current CLI version.
The Tree-sitter library is generally backwards-compatible with languages
generated using older CLI versions, but is not forwards-compatible.
#MIN_COMPATIBLE_LANGUAGE_VERSION
let MIN_COMPATIBLE_LANGUAGE_VERSION : IntThe earliest ABI version that is supported by the current version of the
library.
