library/string.m:
Fix a bug in the word_wrap_separator function, which could cause it
to add unnecessary line breaks. The bug was that it
- insisted all line breaks needed for extremely long words at once, while
- the logic of the code that did that did not consider all the conditions
that the main code path considered.
The fix is to handle adding line breaks to extremely long words
one line break at the time, judging the need for those line breaks
using the main code path.
Improve the documentation of word_wrap and word_wrap_separator.
Replace use of reversed lists with cords where this improves clarity.
Use both predicate names and variable names that directly specify
whether they refer to code units or code points.
Add some XXXs on dodgy code.
For two predicates, inline them at their only call sites.

Expect fixed output from word_wrap_separator.
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.
