Use ibus-m17n as the default IME for Sinhala


The current default input method for Sinhala is ibus-sayura. This should change to the ibus-m17n input method “m17n:si:sayura - sayura (m17n)”


Current status

Detailed Description

The current Fedora default input method ibus-sayura seems to be not actively maintained. Fixing bugs like this one

is therefore difficult.

The ibus-m17n input method si-sayura.mim does exactly the same (I developed this one to be an exact replacement for ibus-sayura).

As ibus-sayura offers no additional benefit, it is probably better to use ibus-m17n with si-sayura as the default input method for Sinhala. ibus-m17n has to be maintained anyway. Therefore, this saves the effort of fixing the unmaintained ibus-sayura.


Benefit to Fedora

Save maintenance cost in maintaining ibus-sayura. si-sayura from m17n-db can be used both with ibus-m17n and with ibus-typing-booster, so actually it is more useful than ibus-sayura.


  • Proposal owners:
    • update langpacks-si to use ibus-m17n and m17n-db

  • Other developers: gnome-desktop3 for default si_LK input method
  • Policies and guidelines: N/A (not a System Wide Change)
  • Trademark approval: N/A (not needed for this Change)
  • Alignment with Objectives:

Upgrade/compatibility impact

The package installed by default will change from ibus-sayura to the packages ibus-m17n and m17n-db for an installation in Sinhala.

How To Test

Install Fedora in Sinhala and check that ibus-m17n and m17n-db are installed. The input method m17n:si:sayura should be available:

$ ibus list-engine | grep m17n:si:sayura
  m17n:si:sayura - sayura (m17n)
  1. Add the m17n:si:sayura input method in the gnome-control-center.
  2. Select it in the gnome-panel.
  3. Open gedit and type: “inWdRiy”
  4. Expected Result: You should get the result “ඉන්‍ද්‍රිය”.

One should get exactly the same results when testing with ibus-sayura, m17n:si:sayura from ibus-m17n and ibus-sayura should behave exactly the same.

User Experience

  • There should be very little difference in typing Vietnamese as ibus-sayura and ibus-m17n with si-sayura.mim behave the same.
  • The setup tool looks a little different.
  • Package sizes and dependent packages are different.
  • Memory usage is different.
