Remap the src_root variable value if it is inside old_src_root.

Save a string to the file. Fail if exception is thrown by underlying operations.

Determine if we have the target (first), id path (second), or both (in which case we also advance the iterator).

C++17 deprecated uncaught_exception() so use uncaught_exceptions() if available.

Some misconfigured MinGW GCC builds add absolute POSIX directories to their built-in search paths (e.g., /mingw/{include,lib}) which GCC then interpre

Return the builtin function pointer if this is a call to an internal builtin and NULL otherwise.

Return the builtin name and its arguments. The builtin function is only used to make sure that args have been checked with the builtin() predicate.

Check if the script command output matches the expected result (redirect value). Noop for redirect types other than none, here_*.

Note: also used by ad hoc recipes thus not static.

Dump ad hoc recipe.

If cl is not empty, then find an installation that contains this cl.exe path. In this case the path must be absolute and normalized.

Extract the project name from bootstrap.build.

Return true if a part of any of the list elements matches the regular expression. See find_search() overloads (below) for details.

Scan the specified directory for any subprojects. If a subdirectory is a subproject, then enter it into the map, handling the duplicates.

The script can reference a program in one of four ways: 1. As an (imported) target (e.g., $cli) 2. As a process_path_ex (e.g., $cxx.path). 3. As a

The cc module is an "alias" for c and cxx. Its intended use is to make sure that the C/C++ configuration is captured in an amalgamation rather than su

Return the value as well as the indication of whether the index/name is in range.

Figure out if name contains stem and, optionally, calculate prefix and suffix.

Resolve metadata value type from type name. Return in the second half of the pair whether this is a dir_path-based type.

Return the MSVC binutils search paths (i.e., what the Visual Studio command prompt puts into PATH).

Return true if the line matches the file name being compiled (printed by MSVC). Return false if it is one of the D9XXX warnings that may be printed be

Return the MSVC system library search paths (i.e., what the Visual Studio command prompt puts into LIB) including any paths from the compiler mode and

Return the MSVC standard library modules.

On Windows we use MSYS2 install.exe and MSYS2 by default ignores filesystem permissions (noacl mount option). And this means, for example, that .exe t

This function as well as the perform_match() above are littered with ugly special cases to support update-during-load. This is unfortunate but felt li

Return true if we have multiple partitions (see below for details).

Convert the program (builtin or process) arguments from names to strings. The function name is only used for diagnostics.
