Hey Phil,<br>
<br>
I'm assuming it means that it returns a <b>tuple(bytesstring_of_block_start_chars, pointer_to_style)</b>, because lexers that implement the blockStart method (like QsciLexerPython) return (None, some_large_number). But why do they always return the byte_string
as None?<br>
<br>
Anyway, I edited the <span>blockStart() and blockEnd()</span> methods of my custom lexer to:<br>
<blockquote><span>def blockStart(self):</span><br>
return b'{', 0<br>
<br>
<div><span>def blockStart(self):</span><br>
return b'}', 0</div>
</blockquote>
and set the qscintilla editors <b><span>setAutoIndent</span>(True)</b> and my custom lexers
<b><span>setAutoIndentStyle</span>(QsciScintilla.AiOpening | <span>QsciScintilla.AiOpening</span>)</b>. Now the next line after inserting a '{' doesn't indent (like in the QsciLexerCPP, for example), but it does unindent when inserting a '}'?
<br>
Example:<br>
<blockquote>if (test) <br>
{<br>
|<- doesn't indent<br>
</blockquote>
Then I manually indent:<br>
<blockquote>
<div>if (test) <br>
{<br>
|<- manual indent with the tab key<br>
test line added;<br>
</div>
</blockquote>
Inserting the '}' character unindents automatically:<br>
<blockquote>
<div>if (test) <br>
{<br>
<br>
test line added;</div>
} <span><- automatically unindented from the previous line's indentation level</span><br>
</blockquote>
I really have no idea if I'm doing something wrong or if I'm misunderstanding something, could you please help?<br>
<br>
P.S.:<br>
I'm also helping Kristof, so that is why we are both posting separately on the same topic.<br>
