tom-tan / hlinum-mode

This library extends linum-mode to highlight current line number.

Notice

This package is obsolete because there is a better alternative in Emacs 26 and later.

Emacs 26 officially provides the display-line-numbers function to show the line numbers and you can use the line-number-current-line face to highlight the current line number. They show the better performance than linum-mode and hlinum-mode.

hlinum-mode

This library extends linum-mode to highlight current line number. It requires Emacs 24.4 or later.

To use this package, add these lines to your .emacs file:

    (require 'hlinum)
    (hlinum-activate)

And by using M-x linum-mode, you can see line numbers with highlighting current line number.

You can customize the color of highlighting current line by changing linum-highlight-face. By default, hlinum highlights current line only in the active buffer. To highlight current line in all buffers, change linum-highlight-in-all-buffersp to t.

hlinum-mode's Issues

Highlight selection

Would it be possible also highlight selection line numbers when there is a selection ?

Conflict with git-gutter

When linum highlighting is enabled alongside git-gutter in the margin, hlinum-mode does not detect this and instead assumes that the margin is one character smaller than it is (see image) if there are git symbols present in the left margin. My configuration works fine if there are no git changes in the file.

hlinum-mode-not-working

I am using doom-emacs.
I tried to install hlinum by declaring it from package.el, M-x package-install, and form package list.
unfortunately, all didn't work. I received an error message from config.el after (require 'hlinum), (hlinum activate).
And I received an error message through initialling emacs!.
I felt that I have to mention that.

hlinum when hl-line-sticky-flag is on

What steps will reproduce the problem?
1. Activate hlinum with hl-line-sticky-flag on
2.
3.

What is the expected output? What do you see instead?

Line numbers should be highlighted in inactive buffers when hl-line-sticky-flag 
is on but this is not the case.

What version of the product are you using? On what operating system?

Current revision.

can this work with emacs26.1 `display-line-numbers`?

from NEWS.26

** Emacs now supports optional display of line numbers in the buffer.
This is similar to what 'linum-mode' provides, but much faster and
doesn't usurp the display margin for the line numbers.  Customize the
buffer-local variable 'display-line-numbers' to activate this optional
display.  Alternatively, you can use the 'display-line-numbers-mode'
minor mode or the global 'global-display-line-numbers-mode'.  When
using these modes, customize 'display-line-numbers-type' with the same
value as you would use with 'display-line-numbers'.

this part from the same stanza you may find interesting.

'linum-mode' and all similar packages are henceforth becoming obsolete.
Users and developers are encouraged to switch to this new feature
instead.
