Description of problem: When you type Sinhala using Wijesekera keyboard layout through ibus the first character gets deleted as soon as you start typing the second character. This is similar to the bug previously reported for Fedora 28 https://bugzilla.redhat.com/show_bug.cgi?id=1617978 How reproducible: (1) Steps to Reproduce: 1. Open Libre Office Writer (6.1.2.1) 2. Switch to Sinhala; Sinhalese (wijesekera (m17n)) 3. Type keys vksIal kjSka 4. Hit space to separate the second word from the first word. And hit space at the end of the first word. Actual results: ක වීන් Expected results: ඩනිෂ්ක නවීන් Additional info: (2) When you try this with emacs the results are a little different. I am including it here assuming this is related to the same issue: This is how to reproduce with emacs: 1. Open emacs 26.1 (build 1, x86_64-redhat-linux-gnu, GTK+ Version 3.23.2) of 2018-08-13 2. Switch to Sinhala; Sinhalese (wijesekera (m17n)) 3. Type keys vksIal kjSka 4. Hit space to separate the second word from the first word. And hit space at the end of the first word. Actual results: ඩනිෂ් කනවී න් Expected results: ඩනිෂ්ක නවීන් This adds a space before the last character of the first word, not where you want the space to be.
What desktop are you using? Gnome? Under Wayland or under Xorg?
(In reply to Mike FABIAN from comment #1) > What desktop are you using? Gnome? Under Wayland or under Xorg? I'm using Gnome under Wayland
There are two ways to use the Sinhala Wijesekera keyboard through ibus: 1) using ibus-m17n (m17n:si:wijesekera) 2) using ibus-typing-booster You are using 1), but I also tested 2) and compared. My test results are as follows: Gnome-Xorg: m17n:si:wijesekera: (It makes no difference whether use-surrounding-text is 0 or 1) gedit: OK libreoffice (writer): OK gnome-terminal: OK (bad rendering, but input works OK) emacs: WRONG. xterm: WRONG, exactly the same way as in emacs typing-booster, si-wijesekera input method: gedit: OK libreoffice (writer): OK gnome-terminal: OK emacs: OK xterm: OK Gnome-Wayland: m17n:si:wijesekera: gedit: OK libreoffice (writer): OK gnome-terminal: OK emacs:WRONG xterm: WRONG, exactly the same way as in emacs typing-booster, si-wijesekera input method: gedit: OK libreoffice (writer): OK gnome-terminal: OK emacs: OK xterm: OK KDE Plasma: m17n:si:wijesekera: gedit: OK libreoffice (writer): OK gnome-terminal: OK konsole: OK kate: OK emacs: WRONG xterm: WRONG typing-booster, si-wijesekera input method: gedit: OK libreoffice (writer): OK gnome-terminal: OK konsole: OK kate: OK emacs: OK xterm: OK (Of course the terminals cannot display Sinhala well, but I can still test whether the input works by typing echo '' > /tmp/test into the terminal, then type the Sinhala between the '' and the return, then look at the contents of the /tmp/test file for example with gedit) According to my tests, the desktop does not seem to make a difference. Sinhala input into programs using XIM like emacs or xterm fails, it fails in exactly the same way for emacs and xterm, I think it fails in the same way for all programs using XIM. Programs using ibus-input modules like gedit, libreoffice, gnome-terminal, konsole, kate, seem to work fine. What is different between your tests and mine is that for me libreoffice works, for you it does *not* work. I don’t understand why, I used a Fedora 29 installation in qemu with all current updates for testing. And what is a bit surprising that using si-wijesekera through ibus-typing-booster *always* works for me, in all programs, even those using XIM like emacs and xterm. So using si-wijesekera through ibus-typing-booster might be a workaround for you until we figure out what the problem with ibus-m17n is.

Thanks very much Mike. I am trying to get ibus-typing-booster going following the instructions given here https://mike-fabian.github.io/ibus-typing-booster/documentation.html and here https://fedoramagazine.org/master-typing-ibus-booster/ But I don't see Sinhala (Typing Booster) or something similar among input sources. Other (Typing Booster) doesn't seem to work with Sinhala. Do I have to remove m17n to use typing booster? Another detail that might be relevant is that my system is not a fresh installation. It has been upgraded through Fedora 27 > 28 > 29. I can confirm that gedit works with ibus-m17n

I'm sorry Mike, please ignore my previous comment! I am now able to use si-wijesekera with ibus-typing-booster. It is somewhat satisfactory. I *can* type better text with it now, so as you suggested, I am going to use it as a temporary solution. But the look and feel is very shaky, wobbly and stressful to the eye if you type for longer periods. In my case I spend many hours writing in Sinhala either with emacs orgmode or LibreOffice. To show the problem, I did some screen-captures comparing Fedora 29 an older system (Ubuntu 18.04.) When you type a word in LibreOffice, the word stretches and shrinks in a weird way with "ං "s in between characters. And in emacs, the word that is being typed is shown inside a dark box (or a label?), slightly below the actual line. Screen captures (uploaded to Nextcloud) : Fedora 29 without Typing Booster. When I type several lines, the deletion seems to be very random/arbitrary. By the look of it, this depends on the character you try to type: https://nc.lohangunaweera.tk/index.php/s/p8qE5WCYf3anerJ Fedora 29 LibreOffice with ibus-typing-booster https://nc.lohangunaweera.tk/index.php/s/5794ta6fNHF6my4 Fedora 29 Emacs with ibus-typing-booster https://nc.lohangunaweera.tk/index.php/s/cSC9c9jKosMKRmz Compare it with an older system and see the difference.

I’ll try to fix ibus-m17n of course, but that might take some time, at the moment I have no clue what is going wrong there, it is good that there is at least some workaround for the moment. ibus-typing-booster feels a bit different to ibus-m17n, but it also has some advantages because it remembers words you typed, if you often type the same stuff, it is often enough to type the first few letters of a word and then select a suggestion. > But the look and feel is very shaky, wobbly and stressful to the eye if you > type for longer periods.

That is unfortunately *always* the case in emacs when using input methods like ibus. emacs supports ibus only via XIM and does not support on-the-spot input style, therefore it cannot show the preedit of such an input method inline, the preedit is always shown as an extra box. It was never otherwise. Depending on the desktop used, this box can have a different style and colour, on Gnome it is a black box with white text.
At first glance I noticed two things in your videos showing the use of ibus-typing-booster in Emacs and LibreOffice: 1) Why is there nothing shown in the gnome-panel when ibus-typing-booster is selected? It is just black. When ibus-typing-booster is selected, 🚀 (U+1F680 ROCKET) should be shown there. Also when switching input methods by typing Super+Space, this rocket emoji should be shown, but in your case there is only black. Don’t you have any emoji font installed? google-noto-emoji-color-fonts-20180814-1.fc29.noarch is a good emoji-font package, I thought this was installed by default. Maybe you lack it because you updated your system. 2) Why does ibus-typing-booster only show the text you just typed and does not show any predictions based on what you typed before or from dictionaries? Maybe you don’t have the si_LK dictionary added in the setup tool of ibus-typing-booster? It can be added in the “Dictionaries and input methods” tab of the setup tool. Or maybe you don’t have hunspell-si installed?
Created attachment 1515498 [details] ~/ibus-typing-booster-si-wijesekera-emacs-gnome-wayland-f29.png In this screenshot you can see that ibus-typing-booster shows a rocket emoji in the gnome-panel. And, in emacs I typed only "vk" and got a popup with 5 lines, the top line shows what I have typed (i.e. what si-wijesekera when typing "vk") below that I see 4 candidates with labels 1, 2, 3, 4. The first two are from the user database, i.e. from what has been typed before, number 3 and 4 are from the Sinhala hunspell dictionary (/usr/share/myspell/si_LK.dic). (In this screenshot they are marked with a little book emoji, that marking of candidates from dictionaries is a new feature which is only available in the upcoming ibus-typing-booster 1.4.0, but you should still see candidates from the Sinhala hunspell dictionary with your version of ibus-typing-booster, only the candidates will not have any special labels attached)

I tried various combinations of options before getting it disabled. I think selecting "Enable suggestions by key" disables the suggestions. It sometimes takes more than 15 seconds for the popup to show the suggestions.

Thanks very much for looking into this! A couple of other distros have the same issue at the moment (I checked Debian (stable), Manjaro and Ubuntu 18.10 over the past couple of days. All have some combination of the same set of problems. They either add a space before the last sentence of a word or delete random characters) > > > And in emacs, the word that is being typed is shown inside a dark box (or a > > label?), slightly below the actual line. > > That is unfortunately *always* the case in emacs when using input methods > like ibus. emacs supports ibus only via XIM and does not support on-the-spot > input style, therefore it cannot show the preedit of such an input method > inline, the preedit is always shown as an extra box.

Until very recently I used SCIM in a very outdated Trisquel 6 installation. It had one character in the box, the character you types last. Not the entire word. I think that's what made me think there's something wrong here. I can get used to the box, if it doesn't delete characters or add random spaces in the middle of the words.

Right, selecting "Enable suggestions by key" makes things a lot faster. If you happen to want the popup to complete some word, you can still type Tab to get the popup. 15 seconds is very slow though, usually the popup should showup *much* faster. Maybe you have the option “Unicode symbols and emoji predictions” enabled. Enabling this option really slows things down a lot.

I updated ibus-m17n to 1.4.1, available here: https://bodhi.fedoraproject.org/updates/FEDORA-2018-b10cae47d5 Unfortunately that makes no difference, the problem when typing into Emacs is still there. I really have to investigate this ...

Of course this has nothing to do with the problem of typing Sinhala, but that the emoji don’t show is still quite weird. I have no idea at the moment what could cause this, it works for me. Do you have the emoji-picker package installed? If yes, it would be interesting whether emoji-picker can display emoji on you system or not. emoji-picker should look like this: http://mike-fabian.github.io/ibus-typing-booster/documentation.html#emoji-picker If you cannot display any emoji at all on your system, I guess it will just show white boxes??

I will release an update for ibus-typing-booster soon though which might improve the user experience for you a bit. You are using the mode where you need to press Tab to see suggestions (because of speed and maybe because you rarely need the suggestions). In ibus-typing-booster-1.4.0 you can choose to have the preedit without an underline, or to get the underline only after you pressed Tab to see suggestions. That means that you don't have to see the underline usually while typing which makes it at least look like a bit more like when typing with ibus-m17n.

Removing the underline (or making it appear when the Tab key is pressed) will be extremely helpful. Even though I rarely rely on suggestions, I find its ability to remember my usage very useful.

And yes, it just shows white boxes. Can you attach a screenshot of this? In emoji-picker, you can switch to a black and white emoji-font, "Symbola". (There is a font switcher menu at the top). If you do that, I *guess* that you will see the black and white emoji. But only in emoji-picker ☹. If you click on an emoji in emoji-picker and then paste it somewhere else, for example into gedit, most likely you will see only blank space in gedit because your system is set up to use color emoji fonts and somehow that doesn't work. If you paste an emoji into LibreOffice, you will probably see it as LibreOffice cannot show emoji in colour yet and always shows them in black and white.

I released the ibus-typing-booster-1.4.0 update now: https://bodhi.fedoraproject.org/updates/FEDORA-2018-f948d3369a but I just remembered that you use Gnome Wayland. Unfortunately under Wayland the preedit style is ignored. Wayland always draws the underline under the preedit, even if the input method requests to turn it off. So ibus-typing-booster does have this nice new option now but it doesn’t work under Wayland ☹. I think sometime in the future this will be fixed in Wayland though and then it will start working.

I also got a couple of issues and enhancement requests to report separately on ibus-typing-booster. Are things likely to improve with Gnome Wayland or should I consider moving to something else (Gnome Xorg, or LXDE for example) if I am to get the full use of it?
I just switched to Xorg. I am now able to type Sinhala in Libre Office without any issue. The look and feel is now identical to the Ubuntu 18.04 system I checked. That too has Gnome Xorg. Problem with emacs still remains. The issues I wanted to report regarding ibus-typing-booster are already reported by others. Example: https://bugzilla.redhat.com/show_bug.cgi?id=1637647 They all point to Wayland.

I already have LXDE installed. Or > should I switch to Gnome Xorg? I don’t know really, it is a matter of preference. Personally I am using i3, but I think all of these are fine. If you like Gnome, you could try Gnome Xorg. Of course Wayland will be the future, and it is already the default, so this really should be fixed in Wayland.

You can probably force your system to use black and white emoji everywhere by creating a file ~/.config/fontconfig/fonts.conf with the following contents (It is weird that colour emoji don’t work, but I have no idea at the moment what could cause this): <?xml version="1.0"?> <fontconfig> <!-- Prefer to match color or black-and-white emoji font. --> <match> <test name="lang"> <string>und-zsye</string> </test> <test qual="all" name="color" compare="not_eq"> <bool>true</bool> </test> <test qual="all" name="color" compare="not_eq"> <bool>false</bool> </test> <edit name="color" mode="append"> <bool>false</bool> <!-- ◀ Choose here --> </edit> </match> <alias binding="same"> <family>emoji</family> <prefer> <family>Symbola</family> <family>Noto Color Emoji</family> <family>Emoji One</family> <family>Noto Emoji</family> </prefer> </alias> </fontconfig>

I have no idea how long this will take.

Yes, unfortunately there are still several problems with input methods on Wayland, not only the preedit styling. Surrounding text support also seems severely broken. I am wondering whether I should at yet another option to ibus-typing-booster to disable surrounding text support as a workaround when surrounding text support is broken ... would be nicer if surrounding text support were fixed though ...

Yes, ibus-m17n with si-wijesekera has a problem with xterm and probably with all programs using XIM. I will look into this, but I expect this is going to be difficult. But ibus-typing-booster works in emacs with si-wijesekera, doesn’t it?

(In reply to Mike FABIAN from comment #30) > > But ibus-typing-booster works in emacs with si-wijesekera, doesn’t it? I encountered more problems with emacs. I uploaded a screenshot and video clip. Even if I ignore the difficulty of having the whole word inside the back box slightly below the actual line, there are places where characters/diacritics/glyphs are shown incorrectly. Gedit shows the word correctly https://bugzilla.redhat.com/attachment.cgi?id=1516073
I now have a reasonably OK workaround as I can use gedit instead of emacs. And Libre Office works fine. Thanks for adding me to other bug reports. I hope they'll get resolved soon.

Clarification: This workaround is satisfactory only after switching to Xorg, and combining with ibus-typing-booster Initial issues are still there for those who want Fedora (Gnome + Wayland) to support Sinhala input out of the box.

I wonder whether this is a problem of ibus-typing-booster or a problem of emacs. If you type into emacs like you do in your video and then mark the finished text with the mouse and then paste it into gedit, what happens? Is the text pasted into gedit still wrong or does it look correct after pasting? Or, another way of doing this: Type into emacs, save into a file. Then view the file in gedit. Does it still look wrong in gedit then? If it becomes correct when viewing in gedit it would mean that rendering of Sinhala in emacs is broken. If loading it into gedit does not fix the problem, it would indicate that something went wrong during input already. What was the sequence of keys you typed in this video?

Hello Mike, I am sorry I didn't have Internet access over the past few days so it took longer than I thought to reply. You are correct. This seems to be a problem with emacs. I created a file using emacs (with ibus-typing-booster). Emacs shows it incorrectly. But when I open the same file in gedit it looks correct. Here's a screenshot https://bugzilla.redhat.com/attachment.cgi?id=1516908 (1) Steps to Reproduce: 1. Open Emacs 26.1 (build 1, x86_64-redhat-linux-gnu, GTK+ Version 3.23.2) 2. Switch to ibus-typing-booster 3. Type keys (fisrt Sinhala line of the image) wlqrq iy rQm 4. Save the file 5. Open it with gedit and compare Expected result අකුරු සහ රූප Actual result in emacs (see attached image) In addition to this, I found emacs doesn't display some characters at all while they are clearly shown by gedit (2) Steps to Reproduce 1. Open Emacs 26.1 (build 1, x86_64-redhat-linux-gnu, GTK+ Version 3.23.2) 2. Switch to ibus-typing-booster 3. Type keys f.daravaka (Second Sinhala line shown in the image) 4. Save file 5. Open it with gedit and compare Expected result ගෝර්ඩ්න් Actual result in emacs ර්ඩ්න් (see attached image) The other two lines also have missing first character in emacs. Where should I take this, should I create a separate bug here or upstream with emacs?

[...] > Where should I take this, should I create a separate bug here or upstream > with emacs? Maybe both? I don’t know enough about Emacs to be able to look into this problem. But I use Emacs myself a log and I am interested to learn more about this, so you can put me into the CC if you report a bug.
@Lohan, Were you able to file a bug?
> Expected result ගෝර්ඩ්න් > Actual result in emacs ර්ඩ්න් (see attached image) It seems to be working in GNU Emacs 27.0.50. The problem still exists in GNU Emacs 26.3 (which the version of Emacs in Fedora 31). GNU Emacs recently changed upstream to using harfbuzz, maybe that fixed it.
This message is a reminder that Fedora 31 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora 31 on 2020-11-24. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '31'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 31 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Created attachment 1730000 [details] screen-capure on emacs
I am able to reproduce same problem on emacs version- 1:27.1-2.fc33. Moving this to next release.
(In reply to Priyam Gupta from comment #43) > Created attachment 1730000 [details] > screen-capure on emacs The issue seems to have evolved a bit over the years, and this is exactly how I experience it on Emacs : spaces are added at wrong places. Words get separated at wrong places as a result. I have now filed bug reports regarding this on both Emacs and ibus bug trackers. 1) Emacs https://lists.gnu.org/archive/html/bug-gnu-emacs/2021-02/msg00391.html 2) IBus https://github.com/ibus/ibus-m17n/issues/27

Not many programs use XIM nowadays, gedit, libreoffice, ... all use some input module and not XIM. > 2) IBus https://github.com/ibus/ibus-m17n/issues/27 Thank you, it seems to be an ibus issue though, not specific to ibus-m17n. I’ll close this bug here because it is getting too confusing and probably open a new one for this "adding the spaces at the wrong place when using XIM" ibus issue.
