@ -15,6 +15,65 @@ Changes in 1.9.1 (since the 1.9.0 prerelease):
|
|||
Previously they would use the `off_t' type, which is fragile since its
|
||||
definition depends on the application's value for `_FILE_OFFSET_BITS'.
|
||||
|
||||
** Automatically compiled files will be placed in ~/.cache, not ~/.guile-ccache.
|
||||
|
||||
Actually, they will be placed in $XDG_CACHE_HOME/guile/ccache/1.9,
|
||||
defaulting to XDG_CACHE_HOME=~/.cache. Users may remove their
|
||||
~/.guile-ccache directories.
|
||||
|
||||
** New language: Brainfuck.
|
||||
|
||||
Brainfuck is a toy language that closely models Turing machines. Guile's
|
||||
brainfuck compiler is meant to be an example of implementing other
|
||||
languages. See the manual for details, or
|
||||
http://en.wikipedia.org/wiki/Brainfuck for more information about the
|
||||
Brainfuck language itself.
|
||||
|
||||
** A number of Scheme files were corrected to be LGPLv3+.
|
||||
|
||||
Some Scheme files imported for the compiler were erroneously labeled as
|
||||
being LGPLv2+ or GPLv2+. This oversight has been fixed.
|
||||
|
||||
** Bytevectors may now be accessed with a C-friendly API.
|
||||
|
||||
New functions: `scm_is_bytevector ()', `scm_c_bytevector_length ()',
|
||||
`scm_c_bytevector_length ()', and `scm_c_bytevector_set_x ()'. See the
|
||||
manual for details.
|
||||
|
||||
** Bytevectors are now accessible using the generalized-vector API.
|
||||
|
||||
As a side effect, this change allows compilation of literal bytevectors
|
||||
(`#vu8(...)').
|
||||
|
||||
** Meta-commands to the REPL work better with strange languages.
|
||||
|
||||
Specifically, meta-commands that take expressions as arguments will use
|
||||
the current language's reader to read those expressions, which may span
|
||||
multiple lines, with readline integration if the user has that enabled.
|
||||
|
||||
** The object code file format has changed.
|
||||
|
||||
The objcode loader will complain about a "bad header cookie" if it
|
||||
happens to find an old file. The workaround for that is currently to
|
||||
find all stale .go files and remove them. This is likely to affect users
|
||||
who have checked out Guile's git repository, not those that build from
|
||||
tarballs.
|
||||
|
||||
** Vector access has been sped up considerably.
|
||||
|
||||
Guile's virtual machine now has vector and bytevector operations. Using
|
||||
Guile to process large amounts of data is now easier. This is because
|
||||
`vector-ref' and `vector-set!' now have fast opcodes. In addition, there
|
||||
are opcodes for `ref' and `set' operations on bytevectors for everything
|
||||
from 8-bit integers to 64-bit floating-point values.
|
||||
|
||||
In the next release, we hope to extend this speedup to other kinds of
|
||||
uniform vectors.
|
||||
|
||||
** And of course, the usual collection of bugfixes.
|
||||

||||
Interested users should see the ChangeLog for more information.

Autocompiled files will be stored in the user's ~/.guile-ccache

ccache's behavior for C files.

Autocompiled files will be stored in the $XDG_CACHE_HOME/guile/ccache
