Keyman developer 10 won't match rules in Odia script


Keyman developer 10 won't match rules in Odia script



I'm making a custom keyboard for Oriya/ Odia script with Keyman developer 10 but it won't do contextual substitutions when all the input is in Odia script. For example


+ [K_K] > U+0B15
+ [K_T] > U+0B24
U+0B15 + U+0B24 > U+0B15 U+0B4D U+0B24
"a" + "b" > U+0B15 U+0B4D U+0B24
U+0B15 + [K_C] > U+0B15 U+0B4D U+0B24



When I test his, I get the desired output when I type 'ab' or 'kc' but not with 'kt'. Any help to explain why line 3 won't work but line 4 does will be appreciated.



I do get this error sometimes when Targets is set to 'any' rather than 'windows'


warning 209A: The rule will never be matched because its key code is never fired.

The reason this isn't working is you are trying to match on a Unicode value instead of a keystroke on line 3:


U+0B15 + U+0B24 > U+0B15 U+0B4D U+0B24



Instead of U+0B24, which is a Unicode character, you need to match on the keystroke, for example:


U+0B24


+ [K_K] > U+0B15
+ [K_T] > U+0B24
U+0B15 + [K_T] > U+0B15 U+0B4D U+0B24



As this third rule has a longer context (U+0B15), it takes precedence over the second rule.


U+0B15



An alternate way to solve this issue is to use a post-processing group. In this model, the output from the first group is fed into the context of the second group. Note that the second group does not include a using keys clause.


using keys


group(main) using keys

+ [K_K] > U+0B15
+ [K_T] > U+0B24
match > use(post)

group(post)

U+0B15 U+0B24 > U+0B15 U+0B4D U+0B24





So matching by letters is supported only in basic Latin? I tested that in cyrillic too and it won't work. What I'm trying to achieve is when two consonants are typed I'd like to automatically U+0B4D in between. So you suggest I do it this way? store(consonants) 'bcdef' store(consonant_keys) [K_B] [K_C] [K_D] [K_E] [K_F] any(consonants) any(consonant_keys) > index(consonants,1) U+0B4D index((consonant_keys,2)

@coldbreeze16, The key identifiers are not really basic Latin; as you are matching on a key identified by "a" which is shorthand for [K_A], which is mnemonic for key C01. The code is nearly right, just needs a + delimiter: any(consonants) + any(consonant_keys) > index(consonants,1) U+0B4D index(consonant_keys,2). You can also consider doing post-processing with a secondary group: + any(consonant_keys) > index(consonants, 1) match > use(post) group(post) any(consonant) any(consonant) > context(1) U+0B4D context(2)

+


any(consonants) + any(consonant_keys) > index(consonants,1) U+0B4D index(consonant_keys,2)


+ any(consonant_keys) > index(consonants, 1)


match > use(post)


group(post)


any(consonant) any(consonant) > context(1) U+0B4D context(2)





Thanks a lot! I have been using a program in Win to type my langauge in Windows, recently I migrated to Mac but needed the same layout. This was a life saver. Already accomplished what I needed, I'll have to delve deeper into these post processing groups.

Opening a url is failing in Swift

Opening a url is failing in Swift breakpointing inside the callback and logging success shows false. I added itms-apps to my plist: LSApplicationQueriesSchemes and put this in my app delegate: func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool { return true } func moreTapped() { let url = NSURL(string: "itms-apps://itunes.com/developer/quantum-productions/id979315877") if #available(iOS 10.0, *) { UIApplication.shared.open(url! as URL, options: [:], completionHandler: {(success: Bool) in }) } else { UIApplication.shared.openURL(url! as URL) } } Are you testing on a real device? – rmaddy Jun 21 at 23:57 I try on a device, get "Cannot Connect to App Store".

Export result set on Dbeaver to CSV

Export result set on Dbeaver to CSV Normally I use Dbeaver for windows and always export my result set like this: run my query --> select the result --> export the result set --> select export to clipboard --> done This step by step puts my result set in my clipboard and I can paste it wherever I want to work with it. The problem is that now I am using dbeaver for mac and this guide is not working. I can go on until the moment that I select my result set like in the image below: exporting data set But once I go further in the process, in the last step I get: no query Note that in "source" it was suppose to show the query that originated the result set, but instead it says just "select. As a result it does't select my result or anything (besides being "successful"). Normally my query would show up there automatically and I couldn't find any option that corrects this problem in the menus. Please help me! Thanks. Aft...
