* Improve modularization at the chared/read boundary, no functional change.schwarze2016-05-221-2/+3
| | | | | | | | | | | | Stop the read.c module from poking the el_chared.c_macro data structure that used to belong to the chared.c module. Given that no other module, not even chared itself, is using that data, move it into the read modules's own opaque data structure, struct el_read_t. That gets rid of one struct, one #define, one struct member, and one function argument in the chared.h interface. OK czarkoff@
* Move the declaration of the function pointer type el_rfunc_tschwarze2016-05-201-9/+3
| | | | | | | | | | | | | | | from the private header "read.h" to the public header <histedit.h>. That's not an interface change, it was already used and documented publicly, merely not properly declared. Improve encapsulation: Make el_read a pointer to an opaque struct in struct editline, such that "read.h" no longer needs to be included from "el.h" but only from the two files using it, read.c and el.c. Only pass the required el_read_t to el_read_{s,g}etfn(), do not pass the full struct editline. OK czarkoff@, also proofread by Christian Heckendorf <mbie at ulmus dot me>.
* Make the read_char() function always take a wchar_t * argument.schwarze2016-03-211-3/+3
| | | | | | | | | | | On first sight, it might look as if this required a bump because it seems to change the public type el_rfunc_t. But we only compile with WIDECHAR, and in that case, there is no change in the interface. This also simplifies some logic by getting rid of the NARROW_READ flag which was broken anyway. OK czarkoff@
* Cleanup of standard header inclusion:schwarze2016-03-201-3/+3
| | | | | | | | | | | | | 1. Add the missing <errno.h> to sig.c. 2. Do not include standard headers from private headers "chared.h" and "el.h", include them directly where needed. 3. Delete a few needless inclusions of <ctype.h>. 4. Sort the standard headers. 5. Delete _GNU_SOURCE weirdness from histedit.h, that file doesn't even need the access to wcsdup(3) mentioned in the comment. 6. Delete some trailing blanks and blanks before tabs. OK czarkoff@
* Update libedit to bring it into sync with the latest version from NetBSD.nicm2010-06-301-3/+3

* First pass at removing clauses 3 and 4 from NetBSD licenses.ray2008-06-261-8/+1
| | | | | | | | | Not sure what's more surprising: how long it took for NetBSD to catch up to the rest of the BSDs (including UCB), or the amount of code that NetBSD has claimed for itself without attributing to the actual authors. OK deraadt@
* Update to NetBSD libedit (from Oct 1, 2003), adding some stringotto2003-10-311-0/+58
cleaning and history bug fixes. The code includes GNU libreadline functionality, but the corresponding header files are not installed, since some libreadline functions are missing. There are some minor API changes, notably: old: EditLine *el_init(const char *, FILE *, FILE *); new: EditLine *el_init(const char *, FILE *, FILE *, FILE *); old: HistEvent *history(History *h, int op, ...); new: int history(History *h, HistEvent *ev, int op, ...); plus some changes in operation names. See editline(3) for details. Tested by djm@, mouring@, jmc@. ok deraadt@
