|
||
Guile 1.0b3
|
||
|
||
Changes since Thursday, September 5:
|
||
|
||
* You can now run Guile without installing it.
|
||
|
||
Previous versions of the interactive Guile interpreter (`guile')
|
||
couldn't start up unless Guile's Scheme library had been installed;
|
||
they used the value of the environment variable `SCHEME_LOAD_PATH'
|
||
later on in the startup process, but not to find the startup code
|
||
itself. Now Guile uses `SCHEME_LOAD_PATH' in all searches for Scheme
|
||
code.
|
||
|
||
To run Guile without installing it, build it in the normal way, and
|
||
then set the environment variable `SCHEME_LOAD_PATH' to a
|
||
colon-separated list of directories, including the top-level directory
|
||
of the Guile sources. For example, if you unpacked Guile so that the
|
||
full filename of this NEWS file is /home/jimb/guile-1.0b3/NEWS, then
|
||
you might say
|
||
|
||
export SCHEME_LOAD_PATH=/home/jimb/my-scheme:/home/jimb/guile-1.0b3
|
||
|
||
* Guile's header files should no longer conflict with your system's
|
||
header files.
|
||
|
||
In order to compile code which #included <libguile.h>, previous
|
||
versions of Guile required you to add a directory containing all the
|
||
Guile header files to your #include path. This was a problem, since
|
||
Guile's header files have names which conflict with many systems'
|
||
header files.
|
||
|
||
Now only <libguile.h> need appear in your #include path; you must
|
||
refer to all Guile's other header files as <libguile/mumble.h>.
|
||
Guile's installation procedure puts libguile.h in $(includedir), and
|
||
the rest in $(includedir)/libguile.
|
||
|
||
* The compiled-library-path function has been deleted from libguile.
|
||
|
||
* A variable and two new functions have been added to libguile:
|
||
|
||
** The variable %load-path now tells Guile which directories to search
|
||
for Scheme code. Its value is a list of strings, each of which names
|
||
a directory.
|
||
|
||
** (%search-load-path FILENAME) searches the directories listed in the
|
||
value of the %load-path variable for a Scheme file named FILENAME. If
|
||
it finds a match, then it returns its full filename. Otherwise, it
|
||
returns #f. %search-load-path will not return matches that refer to
|
||
directories.
|
||
|
||
** (%try-load-path FILENAME :optional CASE-INSENSITIVE-P SHARP)
|
||
searches the directories listed in %load-path for a file named
|
||
FILENAME, and loads it if it finds it. If it can't read FILENAME for
|
||
any reason, it throws an error.
|
||
|
||
The arguments CASE-INSENSITIVE-P and SHARP are interpreted as by the
|
||
%try-load function.
|
||
|
||
|
||
|
||
This is the beginning of recorded history.
