flycheck on Emacs24

flycheck on Emacs24

[haines]

I'm running Debian Wheezy and compiled Emacs 24.3.1 and am using it. I
naturally wanted to upgrade from flymake to flycheck.

I downloaded a flycheck 20140422.657 tar into
/usr/local/share/flycheck. Unarchiving it creates a directory in which
there is flycheck-pkg.el, flycheck.el, flycheck.info.

I didn't know how to install these files, and so tried copying them into
~/elisp.

I added a line in ~/.elisp: 

   (add-hook 'after-init-hook #'global-flycheck-mode)

But when I try to initialize flycheck with M-x global-flycheck-mode
I get:

  M-x global-flycheck [No Match]
 
How should I have installed the file? There weres no directions.

What’s wrong with using emacs own package manager, ELPA? It does it
all for you and is dead simple to use = options -> use package
manager and then just choose what you want to install. Its a lot
quicker and a lot easier and simpler too! And you could have got
emacs too from the wheezy repos, why make life difficult for
yourself?

My crystal ball says the directory where you have the flycheck *.el
files doesn't appear in load-path.  If so, you should add it to that
list.

Thanks for the help. It led to find out about ELPA. While I was at 
it I also modularized my emacs init file. That all worked out nicely,
although it seems gnus init file is no longer auto-line wrapping.

But the bottom line is that I used ELPA to install flycheck. It 
seems to have succeeded at least to the extent it shows up as a minor 
mode when I display a file. How to use it I have yet to look into
because it does not produce the dramatic colored highlight of 
flymake (I see there is an ELPA package to colorize, and I may 
try that). 

I am worried a bit ELPA's compilation of the package. There was an
error that it was unable to activate package "f". The required package
"s-1.7.0" is unavailable. When I look at s.el, I find :

  s-buffer is an installed package.
  Status: Installed in 
     `/home/haines/.emacs.d/elpa/s-buffer-20130605.1424/'.
  Version: 20130605.1424
  Requires: s-1.6.0, noflet-0.0.3
  Summary: s operations for buffers
 
I see that flycheck is no longer displayed in ELPA's package list. 
I wonder if this is because it is installed? The error makes me 
also wonder if the flycheck that I managed to compile and install 
is fully functional, although off hand it seems to be working.

Put this in your ".emacs" -
--8<---------------cut here---------------start------------->8---
(require 'flycheck)
(global-flycheck-mode 1)
--8<---------------cut here---------------end--------------->8---
That will make it work in every buffer with whatever document/text
you’re working with.

Look right down at the bottom of the package list and you should
see it like here -
╭────
│ flycheck   20140422.657 unsigned   On-the-fly syntax checking (Flymake done right)
╰────
If you're unsure about it try doing *C-s flycheck* in the package
list, then it will search for it, and find all instances of
'flycheck', and if you keep pressing *C-s* it will work through all
it finds until you find the one that you are looking for. Sounds
long-winded but it works.

It does colourize, but less intrusive than Flymake by default.  Customise
the flycheck-error, flycheck-warning and flycheck-info faces to change the
colouring.

There is no package that changes his Flycheck highlights errors.

That is a known bug in Emacs 24.3.  See
https://github.com/flycheck/flycheck/pull/372#issuecomment-39475673 for
details and a fix.  The issue is fixed in upcoming Emacs 24.4

It's just a minor nuisance, though, and does not adversely affect Flycheck.

Also note that Flycheck has  comprehensive documentation available at
http://flycheck.rtfd.org/ which includes installation and setup
instructions. Please take the time to read it.
