I want to get contents of the current line(the line with cursor) for my function. What command allows me to achieve this?

  • "the line with the cursor" depends on the selected window, since different windows can have different values for point. (It should never be a problem, but who knows...)

Use buffer-substring:

(buffer-substring (line-beginning-position) (line-end-position))

As Tobias noted, this also copies properties of text. If you want to avoid that, you might want to go with buffer-substring-no-properties instead:

(buffer-substring-no-properties (line-beginning-position) (line-end-position))

    Often it is better to use buffer-substring-no-properties.

Alternative to buffer-substring:

(thing-at-point 'line)

    Be aware that this includes the final newline character if there is one (i.e. always, except maybe for the last line of the buffer) as well as the text properties.
