kre 72c6780ab3 Remove a function prototype which was added to <histedit.h> in 2005. 
I think we can trust it to be stable by now, and doin't need the dup.

kre e8999de45c INTON / INTOFF audit and cleanup. 
No visible differences expected - there is a remote chance that
some internal lossage may no longer occur in interactive shells
that receive SIGINT (untrapped) at inopportune times, but you would
have had to have been very unlucky to have ever suffered from that.

kre c6c29888c4 Remove atoi() 
Mostly use number() (no longer implemented using atoi()) when an
unsigned integer is required, but use strtoXXX() when a conversion
is wanted, without the possibility or error (like setting OPTIND
and RANDOM).   Always init OPTIND to 1 when sh starts (overriding
anything in environ.)

kre 4754b1e8f4 Now libedit supports embedded mode switch sequence, improve sh 
support for them (adds PSlit variable to set the magic character).
 2017-06-28 13:46:06 +00:00
christos 650f73e320 Add literal prompt support this allows one to do: 
CA="$(printf '\1')"
PS1="${CA}$(tput bold)${CA}\$${CA}$(tput sgr0)${CA} "

kre 3c2922e71c Properly support EDITRC - use it as (naming) the file when setting 
up libedit, and re-do the config whenever EDITRC is set.

jmmv 416c5b0ff8 Call el_source before initializing sh-specific editline properties (i.e. 
the editor type and the tab completion binding).

This allows tab completion to work when a user has an ~/.editrc file.

Addresses PR bin/43404.

mrg 084c052803 quell GCC 4.1 uninitialised variable warnings. 
XXX: we should audit the tree for which old ones are no longer needed
after getting the older compilers out of the tree..

aymeric d5d0c11532 Make the -s flag of fc work correctly. Ensure that only one command is specified 
and ensure that we break out of the loop after executing it.
With the previous code, because the re-executed command was added to the
history, it would think that it still had to execute it, leading to an infinite
loop.

The last thing which differs from ksh is that we get the "fc -s " command into
the history, but this is actually rather a feature in my humble opinion.

To test:
$ echo hello
$ fc -s ec
<infinite loop or correct behaviour>

christos 0df4f0ca31 Only do certain actions when we are trully interactive, not just when we 
are connected to a tty:
	1. enable editor
	2. print directory on directory change.
	3. print job messages

christos c3b8cf7d21 Only add the function when we initialize. Restore the binding of tab to 
ed-insert if tabcomplete is cleared.
 2005-05-09 11:35:19 +00:00
dsl 82537bf8e8 If 'set -o tabcomplete' it set, then bind <tab> to the libedit filename 
completion function.
Note that the libedit code will probably want fine-tuning!
While editing the man page, add a note that non-whitespace IFS chars are
terminators and can generate null arguments.

lukem 7568eb663a skip a leading `-' on the arg0 name when calling el_init() 2003-10-27 06:19:29 +00:00
christos 1bbc81a501 Let libedit handle signals so we resize properly. I might change my mind 
later on that.

lukem 1e840c4d40 Ensure that $TERM is set in the real environment before calling el_init(3)

christos c02b3bbdf4 Fixes from David Laight: 
- ansification
- format of output of jobs command (etc)
- job identiers %+, %- etc
- $? and $(...)
- correct quoting of output of set, export -p and readonly -p
- differentiation between nornal and 'posix special' builtins
- correct behaviour (posix) for errors on builtins and special builtins
- builtin printf and kill
- set -o debug (if compiled with DEBUG)
- cd src obj (as ksh - too useful to do without)
- unset -e name, remove non-readonly variable from export list.
  (so I could unset -e PS1 before running the test shell...)
