Hi, unfortunately I haven’t find similar topic and have to create a new one.
I create an input rule which transforms ###+space into a header of level 3 and use standard textblockTypeInputRule for this task (ProseMirror Reference manual).
The unexpected issue is that cursor is always set after the header.
I created my own input rule to workaround the issue where I tried to use tr.setSelection(...) to put cursor into the converted header.
But I failed. My investigation shows that setSelection can set cursor before or after the header but NOT INSIDE it for some reason.
NOTE: after transaction is applied - I can set selection as expected.
So my guess is that setSelection doesn’t work correctly when used in one transaction with .setBlockType(...)
Here is my inputRule for reference:
const isSetSelectionBugFixed = false;
const fixedTextblockTypeInputRule = isSetSelectionBugFixed
? textblockTypeInputRule
: (regexp: RegExp, nodeType: NodeType, getAttrs?: Attrs | null | ((match: RegExpMatchArray) => Attrs | null)) => {
return new InputRule(regexp, (state, match, start, end) => {
const $start = state.doc.resolve(start);
const attrs = getAttrs instanceof Function ? getAttrs(match) : getAttrs;
if (!$start.node(-1).canReplaceWith($start.index(-1), $start.indexAfter(-1), nodeType)) {
return null;
}
let tr = state.tr;
tr = tr.delete(start, end);
tr = tr.setBlockType(start, start, nodeType, attrs);
const selection = new TextSelection(state.doc.resolve(start)); // nor (start) nor (start + 1) nor (start - 1) doesn't work as expected
tr = tr.setSelection(selection);
return tr;
});
};
...
function headingRule(nodeType: NodeType, maxLevel: number) {
return fixedTextblockTypeInputRule(new RegExp("^(#{1," + maxLevel + "})\\s$"), nodeType, function (match) {
return {level: match[1].length};
});
}
Can you please confirm my assumption or point me somewhere if I do / understand something wrong.
Thank you in advance
