Khmer-keyboard for Sangha-laptop

Yes, the layout file is in a location where one needs superuser permissions to edit. This can be acquired by adding sudo in front of the command to edit, typing it into a terminal:

Code: [Select]

sudo gedit /usr/share/X11/xkb/symbols/kh

(if I assume correctly that the text editor "gedit" is installed there. If not, maybe try "xed" or "geany" as alternatives to "gedit" which might be installed.)

But it seems it is not really necessary to edit this layout file to get rid of the undefined Unicode symbols problem, but just in case of wanting to modify the layout further.

To replace the undefined unicode characters with the actual character combinations defined by the NiDA layout, one should simply create a new file "~/.XCompose" or "/home/user/.XCompose" (not to forget the dot '.' as the first character of the filename) with the following contents:

Code: [Select]

<U17ff>	:	"◌ា"
<U17fe>	:	"ោះ" 
<U17fd>	:	"េះ" 
<U17fc>	:	"ុំ" 
<U17fb>	:	"ុះ" 

I also attached the file inside a zip here (because file without certain file endings are not allowed here to be uploaded). This should simply be extracted into the user's home directory ("~" or "/home/user").

Then (maybe after restart) the undefined unicode characters should be replaced when typing by the sequences that are defined there.

Not sure if these combinations all work as intended, and how to really combine anything with the placeholder when typing:
អ◌ា
◌ាអ
Hmm...

I think it is also possible to define more refined rules about what should happen when entering this and that character combination in sequence. But have not yet really understood how.

Upasika Villa also sent me some alternative keyboard layout via DeltaChat, "Khmer Limon Keyboard Layout", attached here as an image.
Does this look more practical than NiDA? Now that I know more or less how it works I could maybe also write a layout for it as an alternative.
But the issue with not knowing how to really combine diacritic and placeholder inputs with other characters while typing remains.

It's maybe more in use now, especially on mobile devices. All is fine Master Moritz and Atma will try what ever tomorrow before noon again.
Combinations of vovels are not really needed, just another required memory store under which key located. Sure fine for those typing with 10 fingers, yet here's the eagle typing group.

I just noticed that the `.XCompose` file has no effect on my own computer. It worked in the office. Does it work on the Sangha laptop?
Seem to be differences in behaviour of different Linux distributions.

There was no occasion to test here further since then, Nyom Moritz . Sadhu for care.
