For example: + + file{test}: in.symbol = '@' + file{test}: in.substitution = lax + + * New 'bash' build system module that provides modularization support for bash + scripts. See the build system manual for all the details. + + * Support for 'binless' (binary-less aka header-only) libraries. + + A header-only library (or, in the future, a module interface-only library) + is not a different kind of library compared to static/shared libraries but + is rather a binary-less, or binless for short, static or shared library. + Whether a library is binless is determined dynamically and automatically + based on the absence of source file prerequisites. See the build system + manual for details. + + * Use thin archives for utility libraries if available. + + Thin archives are supported by GNU ar since binutils 2.19.1 and LLVM ar + since LLVM 3.8.0. + + * Support for archive checksum generation during distribution: + + Now we can do: + + $ b dist: ... \ + config.dist.archives='tar.gz zip' \ + config.dist.checksums='sha1 sha256' + + And end up with .tar.gz.sha1, .tar.gz.sha256, .zip.sha1, and .zip.sha256 + checksum files in addition to archives. + + * Support for excluded and ad hoc prerequisites: + + The inclusion/exclusion is controlled via the 'include' prerequisite- + specific variable. Valid values are: + + false - exclude + true - include + adhoc - include but treat as an ad hoc input + + For example: + + lib{foo}: cxx{win32-utility}: include = ($cxx.targe.class == 'windows') + exe{bar}: libs{plugin}: include = adhoc + + * C++ Modules support: + + - handle the leading 'module;' marker (p0713) + - switch to new GCC module interface (-fmodule-mapper) + - force reprocessing for module interface units if compiling with MSVC + + * Testscript: + + - new mv built + - new --after <ref-file> option in touch builtin + + * New $process.run() and $process.run_regex() functions: + + $process.run(<prog>[ <args>...]) + + Return trimmed stdout. + + $process.run_regex(<prog>[ <args>...], <pat> [, <fmt>]) + + Return stdout lines matched and optionally processed with regex. + + Each line of stdout (including the customary trailing blank) is matched (as + a whole) against <pat> and, if successful, returned, optionally processed + with <fmt>, as an element of a list. + + * Support for name patterns without wildcard characters. + + In particular, this allows the "if-exists" specification of prerequisites, + for example: + + for t: $tests + exe{$t}: cxx{$t} test{+$t} + + * Functions for decomposing name as target/prerequisite name: + + $name.name() + $name.extension() + $name.directory() + $name.target_type() + $name.project() + + * Add support for default extension specification, trailing dot escaping. + + For example: + + cxx{*}: extension = cxx + + cxx{foo} # foo.cxx + cxx{foo.test} # foo.test (probably what we want...) + cxx{foo.test...} # foo.test.cxx (... is this) + cxx{foo..} # foo. + cxx{foo....} # foo.. + cxx{foo.....} # error (must come in escape pairs) + + * Use (native) C and C++ compilers we were built with as defaults for + config.c and config.cxx, respectively. + + * Implement missing pieces in utility libraries support. In particular, we + can now build static libraries out of utility libraries. + + * Built-in support for Windows module definition files (.def/def{}). + + * Project names are now sanitized when forming the config.import.<proj> + variables. Specifically, '-', '+', and '.' are replaced with '_' to form a + "canonical" variable name. + Version 0.7.0 * Initial support for Clang targeting MSVC runtime (native Clang interface, |
