2024-02-20Make json value type prepend non-overriding for consistency with mapBoris Kolpackov1-0/+6
2024-02-20Add string_set buildfile value typeBoris Kolpackov1-0/+22
This exposes the std::set<std::string> type to buildfiles. New functions: $size(<string-set>) Subscript returns true if the value is present and false otherwise (so it is mapped to std::set::contains()). For example: set = [string_set] a b c if ($set[b]) ... Note that append (+=) and prepend (=+) have the same semantics (std::set::insert()). For example: set = [string_set] a b set += c b # a b c set =+ d b # a b c d Example of iteration: set = [string_set] a b c for k: $set ...
2024-02-19Add string_map buildfile value typeBoris Kolpackov1-7/+10
This exposes the std::map<std::string,std::string> type to buildfiles. New functions: $size(<string-map>) $keys(<string-map>) Subscript can be used to lookup a value by key. The result is [null] if there is no value associated with the specified key. For example: map = [string_map] a@1 b@2 c@3 b = ($map[b]) # 2 if ($map[z] == [null]) ... Note that append (+=) is overriding (like std::map::insert_or_assign()) while prepend (=+) is not (like std::map::insert()). In a sense, whatever appears last (from left to right) is kept, which is consistent with what we expect to happen when specifying the same key repeatedly in a literal representation. For example: map = [string_map] a@0 b@2 a@1 # a@1 b@2 map += b@0 c@3 # a@1 b@0 c@3 map =+ b@1 d@4 # a@1 b@0 c@3 d@4 Example of iteration: map = [string_map] a@1 b@2 c@3 for p: $map { k = $first($p) v = $second($p) } While the subscript is mapped to key lookup only, index-based access can be implemented (with a bit of overhead) using the $keys() function: map = [string_map] a@1 b@2 c@3 keys = $keys($m) for i: $integer_sequence(0, $size($keys)) { k = ($keys[$i]) v = ($map[$k]) } Also, this commit changes the naming of other template-based value types (not exposed as buildfile value types) to use C++ template id-like names (e.g., map<string,optional<bool>>).
2024-02-07Add experimental support for JSON value typesBoris Kolpackov1-0/+61
New types: json json_array json_object New functions: $json.value_type(<json>) $json.value_size(<json>) $json.member_{name,value}(<json-member>) $json.object_names(<json-object>) $json.array_size(<json-array>) $json.array_find(<json-array>, <json>) $json.array_find_index(<json-array>, <json>) $json.load(<path>) $json.parse(<text>) $json.serialize(<json>[, <indentation>]) For example, to load a JSON value from a file: j = $json.load($src_base/board.json) Or to construct it in a buildfile: j = [json] one@1 two@([json] 2 3 4) three@([json] x@1 y@-1) This can also be done incrementally with append/prepend: j = [json_object] j += one@1 j += two@([json] 2 3 4) j += three@([json] x@1 y@-1) Instead of using this JSON-like syntax, one can also specify valid JSON input text: j = [json] '{"one":1, "two":[2, 3, 4], "three":{"x":1, "y":-1}' Besides the above set of functions, other handy ways to access components in a JSON value are iteration and subscript. For example: for m: $j print $member_name($m) $member_value($m) print ($j[three]) A subscript can be nested: print ($j[two][1]) print ($j[three][x]) While a JSON value can be printed directly like any other value, the representation will not be pretty-printed. As a result, for complex JSON values, printing a serialized representation might be a more readable option: info $serialize($j)
2024-02-06Add support for value type-specific subscript and iterationBoris Kolpackov1-0/+22
2023-08-09Complete and cleanup function documentation in preparation for auto-extractionBoris Kolpackov1-2/+3
Also: - Move the $target.*() function family from functions-name.cxx to separate functions-target.cxx. - Get rid of the separate $process_path_ex.*() family, merging it with $process_path.*().
2023-06-12Hack around GCC 13 -Wdangling-reference false positivesBoris Kolpackov1-6/+6
See GCC bugs 107532, 110213.
2023-05-09Add support for dumping build system state in JSON format (GH issue #182)Boris Kolpackov1-1/+3
Specifically: 1. New --dump-format option. Valid values are `buildfile` and `json-v0.1`. 2. The --dump option now recognizes two additional values: `match-pre` and `match-post` to dump the state of pre/post-operations. The `match` value now only triggers dumping of the main operation.
2023-03-02Replace deprecated std::aligned_storage with alignasBoris Kolpackov1-3/+4
Based on patch by Matthew Krupcale.

2022-12-14Improve empty simple value to empty list of names reduction heuristicsBoris Kolpackov1-10/+18
Specifically, do not reduce typed RHS empty simple values for prepend/append and additionally for assignment provided LHS is typed and is a container.

2022-10-10Preparatory work for public/private variable distinctionBoris Kolpackov1-32/+107
We still always use the public var_pool from context but where required, all access now goes through scope::var_pool().

2022-06-03Reset value::extra on variable_map value change/version incrementBoris Kolpackov1-4/+15
The reset on each modification semantics is used to implement the default value distinction as currently done in the config module but later probably will be done for ?= and $origin().
