Get current line

[JeppeKlitgaard]

I would like to implement a "copy-line up/down" hotkey like the one I use in VSCode (CTRL + ALT + DOWN copies the current line(s) down).

It might be slightly niche, but perhaps Templater could implement an internal function to get the current line(s).

The signature would be something like:

tp.file.cursor_lines() -> [lines, start_char, stop_char]

Where:

• lines is an array of strings (or string with \n, alternatively) containing the FULL (not just selection) lines that are currently in the selection
• start_char is an int giving the position of the start of the cursor (in the first line)
• stop_char is an int giving the position of the start of the cursor (in the last line)

Examples

would return: [["- Sweep voltage from positive to negative and find _stopping voltage_ where the current of electrons stops"], 4, 4]

---

would return: [["- Sweep voltage from positive to negative and find _stopping voltage_ where the current of electrons stops"], 4, 7]

---

would return:

[
    [
     "- Sweep voltage from positive to negative and find _stopping voltage_ where the current of electrons stops",
     "- Freeing an electron requires overcoming _the work function_"
    ],
    4, 3
]

I realised that this can actually be done using the exposed Obsidian API, though this functionality would probably be nice to have directly in Templater nonetheless.

Hey @JeppeKlitgaard that's a good idea, could you share what you already coded so I can understand your implementation better? From what I see getCursor only returns the EditorPosition, but not the full line of the cursor.

any update？

Pass getCursor().line to getLine to get the full text line at the cursor position.

Here's something I came up with

const doc = this.app.workspace.activeLeaf.view.sourceMode.cmEditor.doc
const cursorPos = doc.getCursor()
const lineText = doc.getLine(cursorPos.line).trim()
const regex = /^(?<pre>[-+*\d\.\s]*\[[x|\s]*\]\s*)(?<text>.*)$/i
const match = regex.exec(lineText)
if (match) {
    const ch = match.groups.pre.length
    doc.setCursor(cursorPos.line, ch)
}

if the current line starts with or similar to "- [ ] ", it sets the cursor position right after this substring.

Note that cmdEditor is depreciated. So I came up with the following:

const editor = this.app.workspace.activeEditor.editor;
const line = editor.getCursor().line;
const input = editor.getLine(line).trim();
editor.setLine(line， "");
