noXCUse: New Open XCU Simple Edition or, No Excuse for bloat and brokenness This package is a collection of implementation of some (but by no means all) of the utilities specified in the SUS/POSIX "XCU" (Shell & Utilities) volume. They are designed to be as simple as possible while meeting the requirements of the standard and general usability considerations (like not being horrendously slow or imposing excessive limitations). Unlike other size-oriented implementations such as Busybox and Toybox, noXCUse does not use a unified binary or significant amounts of shared-across-tools library code, making it easy to cherry-pick the set of tools you need for a particular system. Development priority has been given to the tools whose implementations in Busybox are inadequate; in most cases, it's a matter of Busybox failing to support multibyte characters (UTF-8) in utilities whose primary function is character processing (such as fold and wc). In addition to the "priority" utilities, some low-hanging fruit (that is, utterly trivial utilities) has been included simply "because it's easy". These utilities were developed and tested using musl as the C library, and while they aim to be conforming programs with respect to SUS, they make some assumptions: for example that multibyte character encoding is stateless and that resynchronization is possible. The iconv utility also has a hard-coded list of (as subset of) the charsets supported by musl, since there is no portable way to query the C iconv interface for this information. Finally, note that aside from the iconv utility, no development has been done on these utilities since 2007 (pre-SUSv4/POSIX-2008). I may gradually add more utilities to the collection, but this is completely a side project. Cheers, Rich Felker / dalias
