bash builtin expansion in shell.el

bash builtin expansion in shell.el

[jidanni]

There are plenty of
bash$ help|wc
     46     449    3701
builtin bash commands that the *shell* buffer is unaware of, as it only
knows about $PATH.

So how can I get
bash$ hist<TAB>
to become
bash$ history ?

Either type "history" and then RET, or create aliases and make them  
known to the *shell* buffer in the file ~/.emacs_bash. You can also  
read in the documentation how to delegate the command expansion to  
bash – in your example GNU Emacs' shell-mode tries to fulfil this.

I am a tcsh user. I have no quarrels with tcsh, shell-mode gives me  
enough. Would you like to learn shell-mode, too? I mean, if you want  
to use bash instead of GNU Emacs, why don't you use a more simple  
mode, or no mode at all?

i don't think the example you have is traditional unix. Perhaps you
forgot the dollar sign? Also, in my env, there's no “history” as env
var by default (never heard of that), but there's “$HIST”.

env var expansion works in emacs's shell command in both OS X and
Windows Vista. However, when you run shell in emacs, not necessarly
all your env var in terminal are inherited. The situation is a bit
complex depending on what OS you running.

Completing command name...
No completions of hist
Completing file name...
No completions of ali

What do I do?
alias history=history
alias alias=alias
?

I am using the *shell* buffer in
$ emacs -f shell
instead of trying to use the remote readline functions of
$ ssh very-far-away-and-slow.org

Maybe I need to fool *shell* with a directory on $PATH fill of
executable links with the same names as the bash builtins?
touch bla
chmod 755 bla
ln history alias suspend typeset ... bla

Oops i glossed over your previous message. Just for posterity, never
mind my previous reply. :)

not sure what's your solution.

anyhow, this problem is not difficult to implement. For me, i'd say
few days full time.

• How To Implement Keyword Completion in Emacs
  http://xahlee.org/emacs/elisp_keyword_completion.html

I've also been using this package in the 2 years or so:
it support command and file name completions.

;;; shell-command.el --- enables tab-completion for `shell-command'
 http://namazu.org/~tsuchiya/elisp/shell-command.el

however, it doesn't support bash keywords as in your message. Maybe
ask the person who did icicles... it is a package designed to do all
sort of completions, but i don't know if it solves your case. It's on
emacswiki.
