Provide a layer of indirection between the readline compatibility functions
and our internal implementation, so that we have the freedom to change the
function signature.
The place to change the completion_append_character is
usually somewhere in the `rl_completion_entry_function'
callback which is where one usually can distinguish between
file- or dir-like entries to append a slash for dirs etc.
This does no longer work since `fn_complete()' takes the
`append_character' as argument before the callback is executed,
so that changes to the variable `rl_completion_append_character'
have in fact no effect for the current completion.
Fix by adding a function that returns the rl_completion_append_character,
when it gets passed in a filename in readline emulation.
+ the rl_callback_handler_install takes a pointer to a void function
which has one char * argument (it's called that way in the readline
emulation source, otherwise there's no way to pass the line buffer
to the function which processes the line when EOL is encountered)
+ provide a prototype for that function signature and use it
Makes the callback readline interface work now.
Pass in loads of parameters instead of relying on shed-loads of global
variables to modify the behaviour.
The filename completion code can now be enabled by code that uses el_gets().
(eg /bin/sh)
Change isspace(*char_ptr) to isspace(*char_ptr & 0xff) so that the correct
piece of memory is looked at for the bit mask.
gcc optimises out the '& 0xff' (on i386 at least).
Fixes problems found by gcc when the splurious (int) cast is removed
from the #defines in ctype.h
* Make tok_init(), tok_end(), tok_reset(), tok_line() and tok_str()
publically available in <histedit.h>
* Documented the public functions in editline(3)
* Renamed tok_line() -> tok_str()
* Added new tok_line() which takes a "const LineInfo *" instead of
"const char *" (the former has "cursor" information), and optionally
return the argv index ("int *cursorc") and offset within that index
("int *cursorv"). This means that completion routines can use the
tokenization code to crack the line and easily find which word the
cursor is at. (mmm, context sensitive completion :)
* Fixed TEST/test.c when using "continuation" lines (unmatched quote
or \ at EOL), and added some more DEBUG messages including highlighting
where the cursor is (with a `_').
