build2 build system
This package contains the build2 build system.
build2 is an open source, cross-platform toolchain for building and packaging
C++ code. Its aim is a modern build system and dependency manager for the C++
language that provide a consistent, out of the box interface across multiple
platforms and compilers. For more information see:

Changes
Version 0.17.0
* C++20 modules support improvements:
- Named modules support in Clang, including automatic building of the
`std` and `std.compat` standard library modules from libc++ with Clang
18 or later.
- Named modules support in MSVC, including automatic building of the `std`
and `std.compat` standard library modules.
Note: if combining the standard library modules importation with the
standard library headers inclusion, MSVC 17.10 or later is recommended.
- Modules support can now be enabled for any std.cxx value greater or
equal 20 (including `latest`).
- The "C++ Modules Support" section in the manual has been updated to
match the current state of the implementation.
* The `latest` and `experimental` cxx.std values are now mapped to C++26
from GCC 14 and Clang 18.
* The 23 and 2x c.std values are now mapped to /std:clatest starting from
MSVC 17.9. In particular, this option enables C23 typeof support.
* /Zc:preprocessor is now added for the `experimental` cxx.std value from
MSVC 17.9.
* New string_set buildfile value type.
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
...
* New string_map buildfile value type.
This exposes the std::map<std::string,std::string> type to buildfiles.
New functions:
$size(<string-map>)
$keys(<string-map>)
Subscript can be used to look up a value by key. The result is [null] if
there is no value associated with the specified key. For example:
map = [string_map] a@1 b@2 c@3
b = ($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])
}
* New JSON buildfile value types.
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>])
See "JSON Functions" in the manual for details.
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)
* New json_map and json_set buildfile value types.
These expose the std::map<json_value,json_value> and std::set<json_value>
types to buildfiles.
New functions:
$size(<json-set>)
$size(<json-map>)
$keys(<json-map>)
... More
