Downloads
---------

  Download latest snapshot of the current master branch

  * Clone with HTTPS

    git clone https://gitlab.com/nimf-i18n/nimf.git

  * Download tar.gz

Compiling and installing
------------------------

  * Compiling and installing in the usual way

    If you are using im-config

      ./autogen.sh --with-im-config-data

    Otherwise

      ./autogen.sh

      make
      sudo make install
      sudo ldconfig
      sudo make update-gtk-im-cache
      sudo make update-gtk-icon-cache

  * Compiling and installing in Debian way

    First of all, install devscripts, build-essential, debhelper.

      username:~$ sudo apt install devscripts build-essential debhelper

    After installing devscripts, build-essential perform the following commands.

      username:~$ cd
      username:~$ mkdir tmp-build
      username:~$ cd tmp-build
      username:~/tmp-build$ wget https://gitlab.com/nimf-i18n/nimf/-/archive/master/nimf-master.tar.gz
      username:~/tmp-build$ tar zxf nimf-master.tar.gz
      username:~/tmp-build$ cd nimf-master
      username:~/tmp-build/nimf-master$ dpkg-checkbuilddeps

    You may see something like:

      dpkg-checkbuilddeps: Unmet build dependencies: some-package1 some-package2 ...

    Install all dependent packages and perform the following commands.

      username:~/tmp-build/nimf-master$ debuild
      username:~/tmp-build/nimf-master$ cd ..
      username:~/tmp-build$ ls
      libnimf1_YYYY.mm.dd_amd64.deb
      libnimf1-dbgsym_YYYY.mm.dd_amd64.deb
      nimf_YYYY.mm.dd_amd64.build
      nimf_YYYY.mm.dd_amd64.buildinfo
      nimf_YYYY.mm.dd_amd64.changes
      nimf_YYYY.mm.dd_amd64.deb
      nimf_YYYY.mm.dd.dsc
      nimf_YYYY.mm.dd.tar.xz
      nimf-anthy_YYYY.mm.dd_amd64.deb
      nimf-anthy-dbgsym_YYYY.mm.dd_amd64.deb
      nimf-dbgsym_YYYY.mm.dd_amd64.deb
      nimf-dev_YYYY.mm.dd_amd64.deb
      nimf-libhangul_YYYY.mm.dd_amd64.deb
      nimf-libhangul-dbgsym_YYYY.mm.dd_amd64.deb
      nimf-m17n_YYYY.mm.dd_amd64.deb
      nimf-m17n-dbgsym_YYYY.mm.dd_amd64.deb
      nimf-master
      nimf-rime_YYYY.mm.dd_amd64.deb
      nimf-rime-dbgsym_YYYY.mm.dd_amd64.deb

    Install deb packages.

      username:~/tmp-build$ sudo dpkg -i nimf_YYYY.mm.dd_amd64.deb \
      libnimf1_YYYY.mm.dd_amd64.deb nimf-anthy_YYYY.mm.dd_amd64.deb \
      nimf-libhangul_YYYY.mm.dd_amd64.deb nimf-m17n_YYYY.mm.dd_amd64.deb \
      nimf-rime_YYYY.mm.dd_amd64.deb

    As above mentioned, make the package yourself. Otherwise, request your Linux
    distribution to package Nimf.


Configure
---------

  * For GNOME Shell, use 3rd party gnome-shell-extension-appindicator

    https://github.com/ubuntu/gnome-shell-extension-appindicator
    https://extensions.gnome.org/extension/615/appindicator-support/

  * How to enable Nimf on systems using im-config

      im-config -n nimf

  * How to enable Nimf on systems using systemd v233 or later

    Create a file and write the following lines to ~/.config/environment.d/50-nimf.conf

      GTK_IM_MODULE=nimf
      QT4_IM_MODULE=nimf
      QT_IM_MODULE=nimf
      XMODIFIERS=@im=nimf

    Then append the following line to ~/.xprofile

      export $(/usr/lib/systemd/user-environment-generators/30-systemd-environment-d-generator)


Debugging
---------

  nimf --debug
  nimf-settings --gapplication-service & # for nimf-indicator
  tail -f /var/log/daemon.log # or /var/log/syslog

  export GTK_IM_MODULE="nimf"
  export QT4_IM_MODULE="nimf"
  export QT_IM_MODULE="nimf"
  export XMODIFIERS="@im=nimf"
  export G_MESSAGES_DEBUG=nimf
  gedit # or kate for Qt
