|
A simple cross-platform C++ utility library.
|
|
|
|
Supported compilers: >=clang-5.x, >=gcc7.x; specifically, we require cxx17 features such as structured bindings which aren't present in older compilers. No attempt has been made to compile under MSVC.

=== Environment Variables
|
|
|
|
The following variables can be defined at runtime to change the library behaviour.
|
|
|
|
DEBUG:: whether to initialise basic debugging features at load time. the value is irrelevant; the test is for whether the variable is defined.
|
|
DEBUG_WAIT:: whether to wait for a debugger to attach before executing `main`.
|
|
|
|
LOG_LEVEL:: minimum log level that will render to the logging stream. note that a given level may have been compiled out and may not be present, eg. DEBUG tends to only be present for debug builds.
|
|
BREAK_LEVEL:: minimum log level that will trigger a breakpoint
|
|
|
|
CRUFT_LOG_SINK:: The output driver for logging. One of 'CONSOLE', 'PATH'.
|
|
CRUFT_LOG_PATH:: The output path for the 'PATH' logging driver. This path is subject to path expansion and will be interpreted as relative to the current working directory if it is relative.
|
|
|
|
JOB_THREADS:: default number of threads to spin up for job queues.
|
|
JOB_DEPTH:: the default size of the pending work item queue for a job queue.
|
|
|
|
Ideally one would not resort to using these variables, but they may make debugging a little easier in some circumstances.
