[ANN] Emacs rails.el

Rails
21

Hi Dima,

“Symbol’s value as variable is void: html-mode-abbrev-table” the first
time. The second time I hit ctrl-t it works.

try add in you .emacs this line, if not exists
(setq auto-mode-alist (cons '("\.rhtml$" . html-mode) auto-mode-alist))

Doesn’t help w/ 21.3 or 21.4

Upgrading to CVS HEAD does fix it.

Also, I’ve included ‘snippet.el’ but can’t trigger abbreviation
expansion with TAB. Ideas?

rec - not work?

No. (But I sure want it to! :wink:

Hmm… no ideas
I’m using emacs from cvs 22.0.50.1 (2005/11/26), do not see this
problem

I just upgraded to 22.0.50.1, still no luck with TAB

I’m also running ECB (Emacs Code Browser). Perhaps there’s a conflict?

I tried (kbd “<f8”>) instead of (kbd “”) and that works. Though it
gets me the crappy minibuffer prompt instead of the cool snippet.el
inline mode.

Thoughts?

Try to update rails.el

I rewrited code working with snippets.
There are a lot of changes in this part, of the code.

This must help.

Ok, some minor troubles:

I added find-recursive.el ok. Then ran into the following:

I commented out the following:

;(find-recursive-directory-relative-files “Z:/WWW/cms3/ftp/ror/app/”
“” “\.rb$”)

Tried ctrl-T. It gives:

File /sites/foo.com/TAGS is not a valid tags table

But will work the second time.

TAB still doesn’t work. Nor does CTRL-. Rebount to and that
doesn’t work now either.

If I add ruby-electric.el via ‘add-hook’:

(add-hook 'ruby-mode-hook
(lambda()
(ruby-electric-mode t)
))

It no longer works when I (require 'rails)

Syntax coloring for ruby-mode is disabled.

Let me know if I can be of more help.

Yet I do not know, from for what it can not work

Hi Dima! Big improvements, we’re super close.

re: syntax highlighting

If I comment out the following line in rails-minor-mode:

;******** uncomment and this breaks highlighting
; (visit-tags-table tags-file-name t)

Then syntax coloring starts to work again. Now I don’t have a TAGS
file setup, so perhaps the function is failing and causing the rest of
the hooks not to run? I’m groking elisp a little now, but not enough.

re: TAB key

I’ve removed ECB and just about everything else in my .emacs file.
binding to still doesn’t work, but I can bind to and that
does work.

Here’s what’s left of my .emacs:

;;----------------------------------------------------------------------------
;; Set up syntax highlighting (font-lock)
;;----------------------------------------------------------------------------

(cond ((fboundp 'global-font-lock-mode)
;; Turn on font-lock in all modes that support it
(global-font-lock-mode t)
;; Maximum colors
(setq font-lock-maximum-decoration t)))

(setq ruby-program-name “/usr/local/bin/ruby”)
(autoload 'ruby-mode “ruby-mode” “Mode for editing ruby source files”)
(add-to-list 'auto-mode-alist '(".rb$" . ruby-mode))
(add-to-list 'auto-mode-alist '(".rjs$" . ruby-mode))
(add-to-list 'interpreter-mode-alist '(“ruby” . ruby-mode))

(require 'ruby-electric)

(defun try-complete-abbrev (old)
(if (expand-abbrev) t nil))

(setq hippie-expand-try-functions-list
'(try-complete-abbrev
try-complete-file-name
try-expand-dabbrev))

(require 'rails)

(add-hook 'ruby-mode-hook
(lambda()
(ruby-electric-mode t)
))

That’s it… nothing else (removed ECB, etc)

Note: ruby-mode.el and ruby-electric.el are the latest from CVS
CVS HEAD emacs running in text mode under ssh/putty & screen.

Summary:

Broken Stuff:

  • No TAB key
  • (visit-tags-table) seems to be breaking font-lock

thoughts?

Good stuff:

  • abbrevs, snippet replace mode, Ctrl-T and everything else seem to work
    great.

rails.el rocks! This completely demotivates me from buying a MacBook :wink:

Thanks,

Hi Dima,

Here’s a fix to make TAB work:

         (local-set-key (kbd "TAB") 'ruby-indent-or-complete)

Just replace ‘’ with ‘TAB’ and all is good. Does that work on your
end too?

I can’t find any docs on the (kbd) function in elisp. (Where does one
find this stuff?)

Best,

-San

C-h f kbd RET

(local-set-key [tab] 'ruby-indent-or-complete)

-Rob

Sweet, thanks Rob.

Dima, these fix the keyboard for me:

         (local-set-key (kbd "TAB") 'ruby-indent-or-complete)
         (local-set-key (kbd "RET") 'ruby-newline-and-indent)
         (local-set-key (kbd "DEL") 'backward-delete-char-untabify)

‘’ and ‘RET’ are supposed to be synonomous, but RET works for me
doesn’t.

Emacs + rails.el now bring joy to coding.

Thanks for assistance.
rails.el now display color logs:)
Cool.

With the most recent change I’m getting a ‘Symbol’s function
definition is void: posn-at-point’ when I try to Ctr-t in a
controller method. I’m running a clean build of GnuEmacs 21.4.1 with
ECB installed. I could also use a few pointers for getting my .rhtml
files to behave properly with expansion/tabbing. Here’s my .emacs:

(setq x-select-request-type '(UTF8_STRING COMPOUND_TEXT TEXT STRING))
(setq x-select-enable-clipboard t)
(setq interprogram-paste-function 'x-cut-buffer-or-selection-value)

(load-file “/opt/emacs/common/cedet.el”)

When you’ve got a few minutes, look at the value of global-map
C-h v global-map RET

In general, the argument is described best under define-key
C-h f define-key RET

But the “vector” is symbols or key values

These should be equivalent:
(local-set-key [tab] 'ruby-indent-or-complete)
(local-set-key “\C-i” 'ruby-indent-or-complete)
(local-set-key [9] 'ruby-indent-or-complete)

         (local-set-key [return] 'ruby-newline-and-indent)
         (local-set-key "\C-m" 'ruby-newline-and-indent)
         (local-set-key [13] 'ruby-newline-and-indent)

These are tricky…
(local-set-key [backspace] 'backward-delete-char-untabify)

     ;; the [delete] is likely on the number pad
         (local-set-key [delete] 'delete-char)

     ;; take your chances...
         (local-set-key "\C-?" 'backward-delete-char-untabify)

You can probably guess what these mean: [f8] [C-f11] [S-f3]

Here’s a good way to figure out was a key IS rather than what it does:

C-h c KEYHERE C-h l

That’s “describe-key-briefly” the key you want (which might be more
than one!) “view-lossage”

I use “view-lossage” when my fingers remember a command, but I can’t
:wink: (that stuff happens when you’ve used emacs on numerous platforms
over 20 years and your ~/.emacs file is approaching 1000 lines)
