how to teach emacs that ' + c = ç

how to teach emacs that ' + c = ç

[Filipe Silva]

I've set up my keyboard layout in arch with localectl set-x11-keymap us
pc104 intl

By default, in this layout, the ' is a dead character. It is called a dead
acute. In portuguese, we are used to compose the ç char with ' + c = ç when
using international us-keyboard layouts.

I don't know why, but by default linux distros come configured so that when
you type this combination ' + c= ć, which is an invalid char in Brazilian
portuguese, and so I'm screwed.

So I did this:

   -

   Editing the files:

   sudo vim /usr/lib/gtk-3.0/3.0.0/immodules.cache sudo vim
   /usr/lib/gtk-2.0/2.10.0/immodules.cache

   changing the line

   "cedilla" "Cedilla" "gtk20" "/usr/share/locale"
   "az:ca:co:fr:gv:oc:pt:sq:tr:wa" to "cedilla" "Cedilla" "gtk20"
   "/usr/share/locale" "az:ca:co:fr:gv:oc:pt:sq:tr:wa:en"
   -

   replaced "ć" to "ç" and "Ć" to "Ç" on
   /usr/share/X11/locale/en_US.UTF-8/Compose

   sudo cp /usr/share/X11/locale/en_US.UTF-8/Compose
   /usr/share/X11/locale/en_US.UTF-8/Compose.bak sed 's/ć/ç/g' <
   /usr/share/X11/locale/en_US.UTF-8/Compose | sed 's/Ć/Ç/g' > Compose sudo mv
   Compose /usr/share/X11/locale/en_US.UTF-8/Compose
   -

      add two lines on /etc/environment

      GTK_IM_MODULE=cedilla QT_IM_MODULE=cedilla
      -

      restart my computer.

And all is working fine in firefox, chromium, scite, gvim or any other gui
tool, but no emacs. on emacs, ' + cinsist on producing ć, despite my
efforts.


So I ask you, how can I teach emacs to produce ç and not ć in this scenario?


thanks in advance.

Curious. I have

setxkbmap us_intl

in my init scripts and have the opposite problem (not actually a problem
for me since in my languages ç is not used).

' + c produces ç in Emacs but ć elsewhere.

BUT...

if I start Emacs with -Q, then ' + c indeed produces as the other
applications ć.

After looking at my customizations, tried

LANG=C emacs -Q

and now ' + c gives ç.

Hope this gives you some clues.

Ubuntu 17.04 here.

very interesting. LANC=C emacs really fix the problem. What is happening
here?

maybe this is a bug.

Re: how to teach emacs that ' + c = ç

[Filipe Silva]

Ok, so I implemented a your LANG=C hack in my emacs daemon script:



unamestr=$(uname -a)
if [[ "$unamestr" == *"Linux"* ]] && [[ $unamestr == *"ARCH"* ]]; then
  # fix cedila | ç  in emacs under arch linux
  # hack found here:
http://lists.gnu.org/archive/html/help-gnu-emacs/2017-07/msg00070.html
  LANG=C
fi

emacs.sh --daemon; rc=$?
if [[ ! $rc = 0 ]]; then
  echo -e "there was a ${Red}problem${Rst} starting emacs daemon: $rc"
  exit $rc
else
  echo -e "emacs daemon ${Blue}started${Rst}. success."
fi

boostrap_time=$(emacsclient.sh -e "(emacs-init-time)")
echo -e "emacs daemon boostrap time: ${Cyan}${boostrap_time}${Rst}"


And it works. But why does it works? It feels so fragile.

There's mention on that in the doc (22.2 Language Environments):

#+BEGIN_QUOTE
   To display information about the effects of a certain language
environment LANG-ENV, use the command `C-h L LANG-ENV <RET>'
(`describe-language-environment').  This tells you which languages this
language environment is useful for, and lists the character sets,
coding systems, and input methods that go with it.  It also shows some
sample text to illustrate scripts used in this language environment.
If you give an empty input for LANG-ENV, this command describes the
chosen language environment.
#+END_QUOTE

So it's probably intentional

Ok but there's No `C` Language environment on that list.

What exactly does LANG=C do to emacs?

Re: how to teach emacs that ' + c = ç

[Filipe Silva]

Ok so this line:

$ LANG=pt_BR.UTF-8 emacs -Q

works fine.

so the portuguese user has really to set pt_BR properly in his system for
this to work.

Problem solved!

Thanks everyone.

If you usually write Portuguese I don't think it is a good idea.
Use a layout that produces characters for your language.
I use a Spanish layout and then we have a key for 'ç', just one
keystroke. This character is also used in French and Catalonian.

Some European languages use it.

Another option is, if you definitely want an English keyboard layout,
to use input method for portuguese:

M-x use-input-method RET portuguese-prefix RET

Then either ", c" or "' c" give "ç".
