help correcting web-mode configuration

help correcting web-mode configuration

[Krishnakant]

Hello all,

I previously posted on this list regarding a similar issue.

But I guess my explanation may be a bit confusing.

So I will explain it again.

Basically I have decided to use web-mode for my html and javascript work.

I took the decision because I also use Python based tenplating languages 
like jinja.


Here is my configuration part in context.



(require 'web-mode)
(require 'company)
(require 'company-web-html)                          ; load company mode 
html backend


(add-to-list 'auto-mode-alist '("\\.html\\'" . web-mode))
(add-to-list 'auto-mode-alist '("\\.js\\'" . web-mode))

(add-hook 'web-mode-hook           '(lambda ()              ;; 
Company-mode              (set (make-local-variable 'company-backends) 
(append company-backends '((company-web-html company-yasnippet))))

No matter what I do, the auto complete using company just does not work 
in web-mode.

Also I am not able to get the auto tag completion working.

Can some one help?

Happy hacking.

Hi,

I barely use web-mode because I seldom write HTML etc, but I use
company-mode a lot and find it sometimes tricky to setup.

I noticed that you set company-backends locally, but you have to make
sure it's actually being called.

You can tackle it down by 2 steps:
1. Try command 'company-web-html' or something provided by your company
web-mode package. If it's giving you the completions, this step is
passed. Otherwise, you have problem setting up the package itself.


2. Try command 'company-diag' to see what back-end it's using currently,
and if the back-end it's using is not what you want, maybe you have to
set the company-backends without append. For example:

(defun web-mode-setup-company ()
  (make-local-variable 'company-backends)
  (setq company-backends '(company-web-html)))
(add-hook 'web-mode-hook 'web-mode-setup-company)

Step one pass because I end up doing this manually and it does give me 
completions.

I will try this in an hour on my laptop with Emacs.
Thanks a lot.

This is the output from company-diag

Used backend: company-web-html
Prefix: nil
Completions: none
I get same result of company-diag even after adding your code to init.el
Happy hacking.

Re: help correcting web-mode configuration

[Danny YUE]

This is really strange...

You see, if 'company-diag' says that your back-end gives no completion,
which is actually wrong because 'company-web-something' does work as you
said...

Wait, why the "Prefix" is nil? It should be a string storing the
characters you have typed when invoking the command.

In Emacs Lisp mode if I type "(add" then invoke 'company-diag, I get:
Prefix: "add"
which is correct...

By the way are you using this pacakge?

Re: help correcting web-mode configuration

[Krishnakant]

Sorry my stupidity,

I hadn't started typing when I did company-diag.

here is the output when I try to start <html tag.


Used backend: company-web-html
Prefix: "htm"
Completions:
   #("html" 0 4 (annotation "html")) " -> html"


I guess the completions are not correct.

Happy hacking.

Re: help correcting web-mode configuration

[Danny YUE]

But it seems to be correct, isn't it?

Because anyway the company-mode returns something that seems
reasonable. What's exactly your problem now?

The completion does not start automatically or something?

Yes completion does not start automatically.
I can do M-x and type company-web-html to get completion done.
I can also set it to a keyboard shortcut, but I expected that my 
completion starts after I type 4 characters (that's what I have set for 
completion ).

So this is precisely the problem.
Happy hacking.

Re: help correcting web-mode configuration

[Danny YUE]

Seriously, have you checked the manual? ;-)

There are 2 variables that may be related to this:
`company-minimum-prefix-length' controls how many characters you have to
type before company-complete is invoked.

`company-idle-delay' controls the delay you will wait before auto
completion.

Please check the value of these 2 variables and modify them to some
valid number, e.g. 2 characters with 0.5 second delay.

It is set to 4 and I did it myself.
It works perfectly with python-elpy with company-mode.

That is set to 1 second.
It works perfectly in Python.

I even tryed your suggestion, although there was no point doing so.
Still no change.

That's why I say this is a challenge.
Should I Send you complete init-el file?

Well, please.

I will take some time trying to set up web-mode on my machine and try to
get it work.
But it will be later today...

Hi Danny,

Sorry to disturb you again, but I tryed a lot of things based on my 
modest knowledge about emacs configurations and company-mode.

But I have still not got over my problem.

Did you get some time to check the problem?

happy hacking.
