This should allow programs to report bad command line arguments
(such as --i-am-not-an-option) and still keep going, if they wish.
library/getopt_io.m:
Add record_all_arguments, a version of the existing record_arguments
predicate that processes the entire command line even in the presence
of errors.
To make this possible, rewrite record_arguments' existing code
to separate out the handling of individual options from the code
that decides whether to stop processing. The code of both
record_arguments and record_all_arguments is now a thin veneer
on top of the new record_argument (singular) predicate, which
does the first job above. The separation of concerns and the new,
documented data structures should also make the new code easier
to understand.
library/getopt.m:
Automatic copy of the new getopt_io.m.
NEWS.md:
Announce the new predicate.
RELEASE_NOTES_NEXT:
Add a reminder about deleting getopt_io.m.
Mercury
Mercury is a logic/functional programming language which combines the clarity and the expressiveness of declarative programming with advanced static analysis and error detection features.
More information is available on the website's about pages, in other README files in the source code repository, and in the documentation.
Small sample programs written in Mercury can be found in the samples and extras directories of the source code repository.
README files
The Mercury compiler has two different backends and works on different operating systems. Specific information is contained in individual README files:
-
Bootstrapping discusses how to get Mercury installed.
This is important, as the Mercury compiler is written in Mercury.
-
C Low-level backend
This backend works well with GCC but also works with:
-
High-level backend targets
-
Supported operating systems
-
Other platform information
Other information
See the current release notes for the latest stable release. The news file lists any recent changes. The history file is relevant if you want to find out more about the past development of Mercury. The limitations file lists some ways in which the Mercury implementation does not yet meet its goals.
Information for developers
If you are considering contributing to the Mercury project, the website contains some documents that may be helpful. These include a document about contributions in general and specific information about contributing such as coding styles.
