+
+[1.15.0][] - 2015-09-10
+-----------------------
+
+### Changes
+- Add support for `--disable-eof` and `--disable-sigint` to disable
+  default Ctrl-D and Ctrl-C behavior
+- Add support for `el_no_hist` to disable access to and auto-save of history
+- GNU readline compat functions for prompt handling and redisplay
+- Refactor: replace variables named 'new' with non-reserved word

+HowTo Build Minix Editline
+==========================
+
+Minix editline use the GNU configure tools, which includes autoconf,
+automake and libtool.  This enables high levels of portability and ease
+of use.  In most cases all you need to do is unpack the tarball, enter
+the directory and type:
+
+    ./configure
+
+There are are, however, more options available.  For instance, sometimes
+it is useful to build editline as a static library, type:
+
+    ./configure --disable-shared
+
+By default editline employs a default handler for the TAB key, pressing
+it once completes to the nearest matching filename in the current
+working directory, or it can display a listing of possible completions.
+For some uses this default is not desirable at all, type:
+
+    ./configure --disable-default-complete
+
+An even more common desire is to change the default install location.
+By default all configure scripts setup /usr/local as the install
+"prefix", to change this type:
+
+    ./configure --prefix=/home/troglobit/tmp
+
+Advanced users are encouraged to read up on --libdir, --mandir, etc. in
+the GNU Configure and Build System.
+
+For more available options, type:
+
+    ./configure --help
+
+To build and install, simply type:
+
+    make
+
+followed by
+
+    sudo make install
+
+Good Luck!

+Introduction
+------------
+
+This is a small [line editing][] library.  It can be linked into almost
+any program to provide command line editing and history functions.  It
+is call compatible with the [FSF readline][] library, but at a fraction
+of the size, and as a result fewer features.  It is also distributed
+under a much more liberal [LICENSE][].
+
+The small size (<30k), lack of dependencies (no ncurses needed!), and
+the free license should make this library interesting to many embedded
+developers.
+
+Editline has several optional build-time features that can be enabled by
+by supplying different options to the GNU configure script.  See the
+output from <kbd>configure --help</kbd> for details.  In the `examples/`
+directory you can find some small code snippets used for testing.
+
+Editline is maintained collaboratively at [GitHub][].
+
+
+API
+---
+
+Here is the interface to editline.  It has a small compatibility layer
+to [FSF readline][], which may not be entirely up-to-date.
+
+```C
+    /* Editline specific global variables. */
+    int         el_no_echo;   /* Do not echo input characters */
+    int         el_no_hist;   /* Disable auto-save of and access to history,
+                               * e.g. for password prompts or wizards */
+    int         el_hist_size; /* Size of history scrollback buffer, default: 15 */
+    
+    /* Editline specific functions. */
+    char *      el_find_word(void);
+    void        el_print_columns(int ac, char **av);
+    el_status_t el_ring_bell(void);
+    el_status_t el_del_char(void);
+    
+    /* Callback function for key binding */
+    typedef el_status_t el_keymap_func_t(void);
+    
+    /* Bind key to a callback, use CTL('f') to change Ctrl-F, for example */
+    el_status_t el_bind_key(int key, el_keymap_func_t function);
+    el_status_t el_bind_key_in_metamap(int key, el_keymap_func_t function);
+    
+    /* For compatibility with FSF readline. */
+    int         rl_point;
+    int         rl_mark;
+    int         rl_end;
+    int         rl_inhibit_complete;
+    char       *rl_line_buffer;
+    const char *rl_readline_name;
+    
+    void rl_initialize(void);
+    void rl_reset_terminal(const char *terminal_name);
+
+    void rl_save_prompt(void);
+    void rl_restore_prompt(void);
+    void rl_set_prompt(const char *prompt);
+    
+    void rl_clear_message(void);
+    void rl_forced_update_display(void);
+
+    /* Main function to use, saves history by default */
+    char *readline(const char *prompt);
+
+    /* Use to save a read line to history, when el_no_hist is set */
+    void add_history(const char *line);
+    
+    /* Load and save editline history from/to a file. */
+    int read_history(const char *filename);
+    int write_history(const char *filename);
+    
+    /* Magic completion API, see examples/cli.c for more info */
+    rl_complete_func_t    *rl_set_complete_func(rl_complete_func_t *func);
+    rl_list_possib_func_t *rl_set_list_possib_func(rl_list_possib_func_t *func);
+```
+
+
+Example
+-------
+
+Here is a very brief example to illustrate how one can use Editline to
+create a simple CLI.  More examples are availble in the source tree.
+
+```C
+    #include <stdlib.h>
+
+    extern char *readline(char *prompt);
+
+    int main (void)
+    {
+        char *p;
+
+        while ((p = readline("CLI> ")) != NULL) {
+            puts(p);
+            free(p);
+        }
+
+        return 0;
+    }
+```
+
+
+Build & Install
+---------------
+
+Editline was originally designed for older UNIX systems and Plan 9.  The
+current maintainer works exclusively on GNU/Linux systems, so it may use
+GCC and GNU Make specific extensions here and there.  This is not on
+purpose and patches or pull requests to correct this are most welcome!
+
+1. Configure editline with default features: <kbd>./configure</kbd>
+2. Build the library and examples: <kbd>make all</kbd>
+3. Install using <kbd>make install</kbd>
+
+The `$DESTDIR` environment variable is honored at install.  See
+<kbd>./configure --help</kbd> for more options.
+
+Origin & References
+--------------------
+
+This [line editing][] library was created by Simmule Turner and Rich Salz
+in in 1992.  It is distributed under a “C News-like” license, similar to
+the [BSD license][].  For details, see the file [LICENSE][].
+
+This version of the editline library is forked from the [Minix 3][] source
+tree.  Patches and bug fixes from the following forks, all based on the
+original comp.sources.unix posting, have been merged:
+
+* Debian [libeditline][]
+* [Heimdal][]
+* [Festival][] speech-tools
+* [Steve Tell][]'s editline patches
+
+The version numbering scheme today follows that of the Debian version,
+which can be seen in the [ChangeLog.md][].  The Debian version was
+unknown to the current [maintainer][] for quite some time, so a
+different name and different versioning scheme was used.  In June 2009
+this was changed to line up alongside Debian, with the intent is to
+eventually merge the efforts.
+
+Outstanding issues are listed in the [TODO.md][] file.

+TODO
+====
+
+Issues in need of work. Mostly compatibility with GNU readline, BSD
+[libedit], and usability improvements.
+
+Remember, the general idea is to keep this library editline small with
+no external dependencies, except a C library.
+
+
+Verify custom completion handlers
+---------------------------------
+
+Verify for v1.14.0 that custom completion handlers still work After
+reverting a "fix" in v0.2.2 that made `rl_complete()` a function pointer
+we need to make sure the same functionality is still available with the
+new infrastructure.  Which is more inspired by BSD libedit and GNU
+readline.
+
+
+Check what's needed to run the fileman example
+----------------------------------------------
+
+The BSD libedit library has imported the GNU readline "fileman" example
+into its tree to demonstrate the abilities of that library.  This would
+also be quite useful for this library!
+
+The first task is to investigate the depependencies and form TODO list
+items detailing what is missing and, if possible, proposals how to
+implement including any optional configure flags.
+
+
+Other minor TODO's
+------------------
+
+- Instead of supporting multiline input, try the Emacs approach, line
+  scrolling.
+- Add support for `rl_bind_key()`, currently only en editline specific
+  `el_bind_key()` exists.
+- Make `char *rl_prompt;` globally visible.

+Original Minix README
+=====================
+
+Below is the original Minix editline README file.  It has been
+split into a modified README and LICENSE file.
+
+                 -- Joachim Nilsson, June 7th 2008
+
+-----------------------------------------------------------------
+$Revision: 5 $
+
+This is a line-editing library.  It can be linked into almost any
+program to provide command-line editing and recall.
+
+It is call-compatible with the FSF readline library, but it is a
+fraction of the size (and offers fewer features).  It does not use
+standard I/O.  It is distributed under a "C News-like" copyright.
+
+Configuration is done in the Makefile.  Type "make testit" to get
+a small slow shell for testing.
+
+An earlier version was distributed with Byron's rc.  Principal
+changes over that version include:
+	Faster.
+	Is eight-bit clean (thanks to brendan()cs!widener!edu)
+	Written in K&R C, but ANSI compliant (gcc all warnings)
+	Propagates EOF properly; rc trip test now passes
+	Doesn't need or use or provide memmove.
+	More robust
+	Calling sequence changed to be compatible with readline.
+	Test program, new manpage, better configuration
+	More system-independant; includes Unix and OS-9 support.
+
+This contains some changes since the posting to comp.sources.misc:
+	Bugfix for completion on absolute pathnames.
+	Better handling of M-n versus showing raw 8bit chars.
+	Better signal handling.
+	Now supports termios/termio/sgttyb ioctl's.
+	Add M-m command to toggle how 8bit data is displayed.
+
+There is one known bug:
+	History-searching redraws the line wrong if the text
+	retrieved is shorter then the prompt.
+
+Enjoy,

+.TH EDITLINE 3
+.SH NAME
+editline \- command-line editing library with history
+.SH SYNOPSIS
+.nf
+.B "char *readline(char *prompt);"
+.fi
+.SH DESCRIPTION
+.I Editline
+is a library that provides an line-editing interface with history.
+It is intended to be functionally equivalent with the
+.I readline
+library provided by the Free Software Foundation, but much smaller.
+The bulk of this manual page describes the user interface.
+.PP
+The
+.I readline()
+function displays the given
+.I prompt
+on stdout, waits for user input on stdin and then
+returns a line of text with the trailing newline removed.  The data is returned in a
+buffer allocated with
+.IR malloc (3),
+so the space should be released with
+.IR free (3)
+when the calling program is done with it.
+.PP
+Each line returned is copied to the internal history list, unless it happens
+to be equal to the previous line.  This is configurable if you are building editline
+from source.
+.SS User Interface
+A program that uses this library provides a simple emacs-like editing interface to
+its users.  A line may be edited before it is sent to the calling program by typing
+either control characters or escape sequences.  A control character, shown as a caret
+followed by a letter, is typed by holding down the ``control'' key while the letter
+is typed.  For example, ``^A'' is a control-A.  An escape sequence is entered by
+typing the ``escape'' key followed by one or more characters.  The escape key is
+abbreviated as ``ESC''.  Note that unlike control keys, case matters in escape
+sequences; ``ESC\ F'' is not the same as ``ESC\ f''.
+.PP
+An editing command may be typed anywhere on the line, not just at the beginning.  In
+addition, a return may also be typed anywhere on the line, not just at the end.
+.PP
+Most editing commands may be given a repeat count,
+.IR n ,
+where
+.I n
+is a number.
+To enter a repeat count, type the escape key, the number, and then
+the command to execute.
+For example, ``ESC\ 4\ ^f'' moves forward four characters.
+If a command may be given a repeat count then the text ``[n]'' is given at the
+end of its description.
+.PP
+The following control characters are accepted:
+.RS
+.nf
+.ta \w'ESC DEL  'u
+^A	Move to the beginning of the line
+^B	Move left (backwards) [n]
+^D	Delete character [n]
+^E	Move to end of line
+^F	Move right (forwards) [n]
+^G	Ring the bell
+^H	Delete character before cursor (backspace key) [n]
+^I	Complete filename (tab key); see below
+^J	Done with line (return key)
+^K	Kill to end of line (or column [n])
+^L	Redisplay line
+^M	Done with line (alternate return key)
+^N	Get next line from history [n]
+^P	Get previous line from history [n]
+^R	Search backward (forward if [n]) through history for
+\&	text; must start line if text begins with an uparrow
+^T	Transpose characters
+^V	Insert next character, even if it is an edit command
+^W	Wipe to the mark
+^X^X	Exchange current location and mark
+^Y	Yank back last killed text
+^[	Start an escape sequence (escape key)
+^]c	Move forward to next character ``c''
+^?	Delete character before cursor (delete key) [n]
+.fi
+.RE
+.PP
+The following escape sequences are provided.
+.RS
+.nf
+.ta \w'ESC DEL  'u
+ESC\ ^H	Delete previous word (backspace key) [n]
+ESC\ DEL	Delete previous word (delete key) [n]
+ESC\ SP	Set the mark (space key); see ^X^X and ^Y above
+ESC\ \.	Get the last (or [n]'th) word from previous line
+ESC\ ?	Show possible completions; see below
+ESC\ <	Move to start of history
+ESC\ >	Move to end of history
+ESC\ b	Move backward a word [n]
+ESC\ d	Delete word under cursor [n]
+ESC\ f	Move forward a word [n]
+ESC\ l	Make word lowercase [n]
+ESC\ m	Toggle if 8bit chars display normally or with an
+\&	``M\-'' prefix
+ESC\ u	Make word uppercase [n]
+ESC\ y	Yank back last killed text
+ESC\ v	Show library version
+ESC\ w	Make area up to mark yankable
+ESC\ nn	Set repeat count to the number nn
+ESC\ C	Read from environment variable ``_C_'', where C is
+\&	an uppercase letter
+.fi
+.RE
+.PP
+The
+.I editline
+library has a small macro facility.
+If you type the escape key followed by an uppercase letter,
+.IR C ,
+then the contents of the environment variable
+.I _C_
+are read in as if you had typed them at the keyboard.
+For example, if the variable
+.I _L_
+contains the following:
+.PP
+.RS
+^A^Kecho '^V^[[H^V^[[2J'^M
+.RE
+.PP
+Then typing ``ESC L'' will move to the beginning of the line, kill the
+entire line, enter the echo command needed to clear the terminal (if your
+terminal is like a VT-100), and send the line back to the shell.
+.PP
+The
+.I editline
+library also does filename completion.
+Suppose the root directory has the following files in it:
+.PP
+.RS
+.nf
+.ta \w'core   'u
+bin	vmunix
+core	vmunix.old
+.fi
+.RE
+.PP
+If you type ``rm\ /v'' and then the tab key.
+.I Editline
+will then finish off as much of the name as possible by adding ``munix''.
+Because the name is not unique, it will then beep.
+If you type the escape key and a question mark, it will display the
+two choices.
+If you then type a period and a tab, the library will finish off the filename
+for you:
+.PP
+.RS
+.nf
+.RI "rm /v[TAB]" munix ".[TAB]" old
+.fi
+.RE
+.PP
+The tab key is shown by ``[TAB]'' and the automatically-entered text
+is shown in italics.
+.SH USAGE
+To include
+.I readline()
+in your program, simply call it as you do any other function. Just make sure to link
+your program with libeditline.
+.SS Example
+The following brief example lets you enter a line and edit it, then displays it.
+.nf
+.B ""
+.B #include <stdlib.h>
+.B ""
+.B extern char *readline(char *prompt);
+.B ""
+.B int main (void)
+.B {
+.RS
+.B     char *p;
+.B ""
+.B     while ((p = readline("CLI>"))) {
+.RS
+.B         puts(p);
+.B         free(p);
+.RE
+.B     }
+.B ""
+.B     return 0;
+.RE
+.B }
+.fi
+.SH BUGS AND LIMITATIONS
+Does not handle multiple lines or unicode characters well.  See the TODO
+file in the distribution if you want to help out.
+.SH AUTHORS
+The original editline library was created by Simmule R. Turner and Rich
+$alz.  It now exists in several forks: Heimdal, Festival speech tools,
+Mozilla, Google Gadgets for Linux, and many other places.  The original
+manual page was made by David W. Sanderson.  Currently maintained by
+Joachim Nilsson at http://github.com/troglobit/editline
