Virtual keyboards

If some of your languages use non-ASCII characters, it might be a good idea to add a virtual keyboard. The user can enable or disable virtual keyboards for main language-dependent text boxes by clikcing on a keyboard sign. The virtual keyboard is based on the KioskBoard plugin.

This is how you can add virtual keyboards for all or some of your languages:

  1. Add keyboards dictionary in corpus.json. Write language/tier names as keys and keyboard IDs as values.

  2. For each keyboard ID, you have to create a keyboard file in /search/web_app/static/keyboards. The files describe keyboards in JSON format. The file should be named keyboard-%KEYBOARD_ID%.json. The file should contain a list where each element describes one row of keys. Each row contains a list of strings, one per key. Here is a small example:

 1[
 2  [
 3    "w",
 4    "e",
 5    "ə",
 6    "ɤ"
 7  ],
 8  [
 9    "a",
10    "s",
11    "š",
12    "šʼ"
13  ],
14  [
15    "z",
16    "ž",
17    "žʼ"
18  ]
19]

  1. If you have different input methods for some language, you can create different keyboards for different input methods. Name your keyboard files keyboard-%KEYBOARD_ID%__%INPUT_METHOD_NAME%.json. If Tsakorpus finds no file for a specific input method, it will look for a generic keyboard for that language.

The keyboards are assigned independently to text boxes in each query word, depending on the language/tier selected by the user for that particular word. The keyboard for the full-text search text box is assigned based on the language/tier of the first query word.
