[ast-developers] latest ast beta source posted

Discussion:

We have posted the latest ast beta source packages. I have been working on
trying to provide a bash compatibility mode and have added a number of new
features to ksh93 itself. When the ksh is liked and run as bash, several
bash features are enabled and
bash rc files are processed.

One of the major new additions, is programmable tab completion with the
editor which is enabled in both bash mode and ksh mode. Since this is
complex and has little automatic testing, I would appreciated any feedback.
I am sure that I missed a few things.

There are many other additions. Read the RELEASE file in src/cmd/ksh93 for
more
information.

We would like to get an official release in 3Q14.

I don't know if this got through so I am resending:

"FUNCNAME" might be good to have because it's related to "BASH_SOURCE" in a
similar manner as ".sh.fun" and ".sh.file".

I tried implementing FUNCNAME using the debugger. The trouble is expanding
"${FUNCNAME[@]}". The hack on the last line makes it sort-of work by pushing
new elements on the end during expansion, but then it can't shrink.

function FUNCNAME.get {
nameref self=${.sh.name}
if (( .sh.subscript < .sh.level )); then
trap "(( .sh.level -= .sh.subscript + 1 )); eval '(( .sh.level = ${.sh.level} ))' \; _=\${.sh.fun}" DEBUG
trap - DEBUG;
fi

(( .sh.subscript < .sh.level - 2 )) && self[.sh.subscript + 1]=
}

Still lots of goodies in RELEASE I've yet to play with.

I had these errors when I tried out completion on Ubuntu 12.04.4 LTS.

It typed "git he" and pressed tab to see if it would complete the word "help":

$ ./bash -l
bash: warning: shell level (5404176) too high, resetting to 1
danny at danny-ubuntu ~/wrk/ksh/ast-ksh.2014-06-25/arch/linux.i386-64/bin
$ git he<tab>

This is what happens next (btw, it backspaced over the 'e'):

$ git hbash: _upvars: cword: invalid option
./bash: _git[22803]: compgen[3]: add: not found [No such file or directory]
./bash: _git[22803]: compgen[4]: get-tar-commit-id: not found [No such
file or directory]
./bash: _git[22803]: compgen[5]: reflog: not found [No such file or directory]
./bash: _git[22803]: grep: no pattern
./bash: _git[22803]: compgen[7]: relink: not found [No such file or directory]
./bash: _git[22803]: compgen[8]: am: not found [No such file or directory]

./bash: _git[22803]: compgen[11]: annotate: not found [No such file or
directory]
./bash: _git[22803]: compgen[12]: apply: not found [No such file or directory]

(Many more similar errors after this)

Did you link ksh93 to bash and run this version of bash? ksh93 has to
emulate bash to be able to run the bash functions since there are a few
incompatibilities.

I think it created the hard link itself:

danny at danny-ubuntu ~/wrk/ksh/ast-ksh.2014-06-25/arch/linux.i386-64/bin
$ ls -li bash ksh
934962 -rwxrwxr-x 2 danny danny 1984736 Jul 1 10:32 bash

I just noticed that "print -j" leaves a trailing comma which is currently
non-conforming json syntax. This will hopefully change: http://json5.org/

$ echo ${.sh.version}; compound xx=(this=that integer x=5); print -j xx
Version ABIJM 93v- 2014-06-25
{
"this": "that",
"x": 5, <---- Trailing comma
}

Tried with my ~4k lines of bashrc (on Solaris 11.0 sparc). Found following
problems when running as bash:

- does not support `>&'
- does not support `type -P'
- does not `export -n'
- has no `bind' command
- does not support some `shopt' options
- PS1 magics does not work well. E.g.: \h, \V, \[
- In the interactive shell, $? is always 0 even if the latest command fails.
- The `alias' (with not arguments) output not compatible with bash.
