2011/2/25 David Robillard :

Given the discussions we had already, NASPRO core could be a viable alternative.

Pros:
- no dependencies apart from libc and libm
- size (181K without stripping on Arch Linux x86-64, -O2)
- high portability, little and confined platform-specific code,
compiler-specific (symbol visibility, etc.) code confined to a small
header
- gracefully handles platform-specific conventions (i.e., ':' vs ';'
in path variables, zero-length prefixes in path variables under *nix,
directory separators, etc.)
- total amount of code is circa 7.5k lines, including comments and
public headers
- UTF-8 support, conversion from/to UTF-16 LE, serious UTF-8 grapheme
counting is supported
- thread safety (e.g., data types are synchronized at a very granular
level, but allow you to have more coarse synchronization if you want)
- extremely low memory footprint
- locale-independent asprintf() and vasprintf(), C99 level (except
"%lc" and "%ls" conversions, possibly they are not even needed if
using UTF-8)
- semi-serious, integrated and as-lightweight-as-it-can-be
error/message reporting mechanism
- precise and well defined error checking and error codes
- includes directory traversal, dynamic loading
- well documented

Cons:
- not yet released
- no real test suite and not extensively tested
- currently implemented data types: doubly linked lists and AVL trees only
- not yet ported to non POSIX platforms (i.e., Windows)
- API/ABI are "stable enough", but can't guarantee for total stability
in the next future (i.e., no big changes will happen, yet something
might change)
- no locale-independent sscanf() or similar
- no UTF16-BE support/conversion
- till now, a one man effort

That is, it is certainly possible to make it become viable to replace
SLV2, but this is not high priority for me at the moment. Once the new
NASPRO release is out I can consider whether to do the work, since I
want to port SLV2 to Windows right after.

The decision, however, depends on whether Dave would like that or not.

Stefano
