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.
2022-12-15Add noexcept to move constructors and move assignment operatorsKaren Arutyunov1-3/+9
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.
2022-11-30Reserve targets, variables to avoid rehashingBoris Kolpackov1-0/+19
2022-10-13Work around Clang 6, 7 codegen issuesBoris Kolpackov1-1/+0

2022-10-13Add visibility, overridable variable attributesBoris Kolpackov1-0/+3
2022-10-13Switch to public/private variables modelBoris Kolpackov1-2/+9
Now unqualified variables are project-private and can be typified.
2022-10-11Factor variable patterns out of variable_pool into separate variable_patternsBoris Kolpackov1-67/+131
We have patterns only for the public variables pool.
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().
2022-10-10Use term shared instead of global for scope, var pool, etcBoris Kolpackov1-18/+20
2022-07-07Use new cmdline type for canned command lines in {Build,Test}scriptBoris Kolpackov1-0/+29
2022-07-05Recognize special .for_install variable suffix in library user metadataBoris Kolpackov1-1/+16
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().

2021-05-28Add support for regex-based target type/pattern specific variablesBoris Kolpackov1-4/+60
This is in addition to the already supported path-based target type/pattern specific variables. For example: hxx{*}: x = y # path-based hxx{~/.*/}: x = y # regex-based
2021-05-28Ban conversion of patterns to valuesBoris Kolpackov1-0/+2
Also improve conversion diagnostic.

2020-06-09Make metadata variable prefix mandatoryBoris Kolpackov1-1/+4
While we could automatically set it if the target is imported, there is nothing we can do if the target is used in the same project. So to avoid confusion we make it mandatory.
