slsh (slang-shell) is a work in progress. See the scripts/
subdirectory for some trivial examples of its use.
Usage: slsh [OPTIONS] [[-|file] [args ...]]
--help Print this help
--version Show slsh version information
-g Compile with debugging code, tracebacks, etc
-n Don't load personal init file
-i init-file Use this file instead of default
-v Show verbose loading messages
Along with the slsh executable, the files lib/slsh.rc and lib/*.sl
will also get installed.
Upon startup, the program will try to load slsh.rc as follows:
If either SLSH_CONF_DIR or SLSH_LIB_DIR environment variables
exist, then look in the corresponding directories for slsh.rc.
Otherwise look in:
$(prefix)/etc (specified in Makefile)
/usr/local/etc/
/usr/local/etc/slsh/
/etc/
/etc/slsh/
The slsh.rc file may load other files from slsh's library directory in
the manner described below.
Once slsh.rc is loaded, slsh will load $HOME/.slshrc if present.
Finally, it will load the script specified on the command line. If
the name of the script is "-", then it will be read from stdin.
When a script loads a file via the built-in "evalfile" function or the
"require" function (autoloaded by slsh.rc), the file is searched for
along the SLSH_PATH as specified in the Makefile. An alternate path
may be specified by the SLSH_PATH environment variable.
The search path may be queried and set during run time via set the
get_lib_path and set_lib_path functions, e.g.,
set_lib_path ("/home/bill/lib/slsh:/usr/share/slsh");
