|

This is an example how to implement your own highlighter.
|
||||
|
||||
This example does allow to specify different colors for
|
||||
- text (defaults to not-highlighted)
|
||||
- spaces (defaults to silver frame)
|
||||
- words, separated by spaces, that start with a,e,i,o,u (defaults to bold)
|
||||
- the word "not" (defaults to red background)
|
||||
|
||||
See comments below and http://wiki.lazarus.freepascal.org/SynEdit_Highlighter
|
||||
|
||||
How it works:
|
||||
|
||||
- Creation
|
||||
The Highlighter creates Attributes that it can return the Words and Spaces.
|
||||
|
||||
- SetLine
|
||||
Is called by SynEdit before a line gets painted (or before highlight info is needed)
|
||||
This is also called, each time the text changes fol *all* changed lines
|
||||
and may even be called for all lines after the change up to the end of text.
|
||||
|
||||
After SetLine was called "GetToken*" should return information about the
|
||||
first token on the line.
|
||||
Note: Spaces are token too.
|
||||
|
||||
- Next
|
||||
Scan to the next token, on the line that was set by "SetLine"
|
||||
"GetToken*" should return info about that next token.
|
||||
|
||||
- GetEOL
|
||||
Returns True, if "Next" was called while on the last token of the line.
|
||||
|
||||
- GetTokenEx, GetTokenAttribute
|
||||
Provide info about the token found by "Next"
|
||||
|
||||
- Next, GetEOL. GetToken*
|
||||
Are used by SynEdit to iterate over the Line.
|
||||
Important: The tokens returned for each line, must represent the original
|
||||
line-text (mothing added, nothing left out), and be returned in the correct order.
|
||||
|
||||
They are called very often and should perform ath high speed.
|
||||
|
||||
- GetToken, GetTokenPos, GetTokenKind
|
||||
SynEdit uses them e.g for finding matching brackets. If GetTokenKind returns different values per Attribute, then brackets only match, if they are of the same kind (e.g, if there was a string attribute, brackets outside a string would not match brackets inside a string)
