text-editor

问题 I have been working on the creation of a specialized text editor running in the browser. I've got a question that has put me in a stupor. How to detect and divide long text into separate pages, as is done in Google docs? I know that google docs does not work through contenteditable, but there must be some solution... Edit1: We need to consider a few scenarios: We load a document by means of json object and then rendering our pages. We are typing the text and reached the end of the page. We

问题 This is an interview question. What data structure would you use to store the text in a text editor? 回答1: On good old ZX-Spectrum one (or more, I do not know) text exditor used very simple structure. There was one big buffer, which occupied all free RAM. Text was split in two parts at the cursor. Part before the cursor, was placed at the beginning of the buffer, and the rest at the end of the buffer. As text typed, data simply added to the end of first part, and when cursor is moved, text is

问题 If i set the following option in Vim, set textwidth=80 the text will break at 80 characters. This works, but the problem is if a comma (,) is on the end of a line, Vim indents the next line.

问题 Suppose I have a JTextPane with HTMLEditorKit. I'm displaying a paragraph of text and want to capture events when user clicks on individual word or presses a certain hotkey while a word is highlighted. For example, when a word is highlighted and user presses D, the word is removed from the text. Also, how to implemented custom cursor navigation - that is, move cursor on word boundaries only? What would be the simplest way to implement these features? I realise this is a lot of code, so just

问题 I am wondering how you can change the cursor position in draft.js after having done an text insertion on key command. Therefore I am currently using _handleKeyCommand(cmd) to insert a custom text block whenever the user presses a specific button. Next I tried the following: currentState = this.state.editorState; var selectionState = this.state.editorState.getSelection().getStartKey(); this.setState({editorState: EditorState.forceSelection(currentState, selectionState)}); But this keeps

I use it all the time as a secondary editor, for various scripting and other programming tasks. Tons of features, free, open source. 回答2: Zeus can

问题 I have a custom UITextView with custom line spacing applied. When I try to select the text the selectionRect is wrong. Check this image where highlighting is correct but the size of the handles at selectionRange start and end is wrong. That particular line has beforeSpacing of 50px and afterSpacing of 10px applied. Instead I want it to behave like this I modified the cursor size using caretRectForPosition: and modified the position and size of the cursor by changing its rect, but
