This module was developed by referring to the official BR API. However, there is a difference in that it is implemented with a slightly different logic, such as not highlighting special characters. I'm going to talk about this here.
First, I found the rule below through the BR API call result.
At first, I tried to find a Pattern by adding characters one by one. Below is the result:
| Length (Min) | Length (Max) | Max - Min | Number of Non-Highlighted Chars |
|---|---|---|---|
| 0 | 4 | 4 | 1 |
| 5 | 12 | 7 | 2 |
| 13 | 16 | 3 | 3 |
| 17 | 24 | 7 | 4 |
| 25 | 29 | 4 | 5 |
| 30 | 35 | 5 | 6 |
| 36 | 42 | 6 | 7 |
| 43 | 48 | 5 | 8 |
I couldn't find a specific pattern here but thought I could use a Heuristic instead.
Pneumonoultramicroscopicsilicovolcanoconiosis (45 Letters)
The above word is the longest word that exists in the dictionary. That means, the number of characters will never exceed 46. So, I implemented the logic that I don't care about characters longer than a specific number of characters.
Below are the final rules for character count:
| Length (Min) | Length (Max) | Max - Min | Number of Non-Bold Chars |
|---|---|---|---|
| 0 | 4 | 4 | 1 |
| 5 | 12 | 7 | 2 |
| 13 | 16 | 3 | 3 |
| 17 | 24 | 7 | 4 |
| 25 | 29 | 4 | 5 |
| 30 | 35 | 5 | 6 |
| 36 | 42 | 6 | 7 |
| 43 | 48 | 5 | 8 |
| 49 | infinity | infinity | 9 |
The above is a description of the fixationPoint option value of 1, and the same is done for other cases. See here for a complete list of test results for Fixation Points.
Special characters at the Beginning or End of a word are not highlighted.
';apple;' -> ';<b>app</b>le;'Special characters placed inside words are treated the same as Regular characters.
'a;ppl;e' -> '<b>a;ppl</b>;e'However, a Dash (-) among special characters located inside a word is treated the same as a Space.
'app-le' -> '<b>ap</b>p-<b>l</b>e'I thought it was awkward to highlight special characters, so I implemented it to divide them based on special characters.
// Origin 'a;ppl;e' -> '<b>a;ppl</b>;e' 'app-le' -> '<b>ap</b>p-<b>l</b>e' // This module 'a;ppl;e' -> 'a;<b>pp</b>l;e' 'app-le' -> '<b>ap</b>p-<b>l</b>e'
If there are only numbers, highlight nothing.
'1234567890' -> '1234567890'If there is a dash between the numbers, it is also not highlighted.
'1234-567890' -> '1234-567890'When numbers and letters are used together, they are treated as regular characters.
'a1234567890' -> '<b>a12345678</b>90'
'1234567890a' -> '<b>123456789</b>0a'
'1234a567890' -> '<b>1234a5678</b>90'If a special character other than a dash is between numbers, treat it like a regular character.
'1234!567890' -> '<b>1234!5678</b>90'Otherwise, it doesn't highlight anything.
'!1234567890' -> '!1234567890'
'1234567890!' -> '1234567890!'Note: Emojis are treated as special characters, not dashes.
This module does not highlight even if there are special characters between numbers.
// Origin '1234!567890' -> '<b>1234!5678</b>90' // This module '1234!567890' -> '1234!567890'
