HowTo Build Minix Editline
|
||||
==========================
|
||||
|
||||
Minix editline makes use of 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!

The editline library was created by Simmule Turner and Rich Salz back in 1992.

At the time they chose to distribute the code under a "C News-like" copyright,
|
||||
see the file LICENSE for details.
|
||||
|
||||
The small size (<30k), lack of dependencies (no ncurses needed!) and the free

license should make this library interesting to many embedded developers.

This version of the editline library is a fork off the Minix3 sources. Other

know versions, often based off of the original comp.sources.unix posting are:
|
||||
Before finding out about the Debian version I was on the lookout for a really
|
||||
small replacement for the GNU readline package. Not only was libreadline large
|
||||
and GPL:ed (instead of LGPL:ed), it also depends on libncurses, the resulting
|
||||
size was a bit too much for my embedded system. I eventually stubmled upon the
|
||||
BSD libedit library, which was sufficient for a while, even though it too
|
||||
depends on libncurses. I searched my soul and went back to where I, back in
|
||||
1996, started out -- Minix. And there it was, a really small readline
|
||||
replacement!

Outstanding issues are listed in the TODO file.
|

In 2000 Jim Studt packaged libeditline for Debian[1], the exact origin of the
|
||||
Debian code base is unclear, see the Sid package[2] for details. There were
|
||||
some notable differences between that version and the upstream Minix sources,
|
||||
all of which have now been merged here.
|
||||
|
||||
An explanation of the version numbering may be in order. I didn't know about
|
||||
the Debian version for quite some time, so I kept a different name for the
|
||||
package and a different versioning scheme. In June 2009, I decided to line up
|

alongside Debian, with the intent of merging the efforts.

Issues in need of work. Mostly compatibility with GNU readline, BSD libedit,

http://www.thrysoee.dk/editline/, and usability improvements.

Remember, the general idea is to keep Minix editline small.
|

|

* Verify for 1.14.0 that custom completion handlers still work

After reverting "fix" in 0.2.2 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.

* Investigate GNU readline dependencies needed for "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 Minix editline.
|

* Add support for rl_bind_key(), currently only en editline specific el_bind_key() exists.
|

|
||||
* Add support for inhibiting completion: rl_inhibit_completion
|

* Make "char *rl_prompt" globally visible.
