simmel/urxvt-resize-font

Installation

1. Copy resize-font to where URxvt looks for Perl extensions, e.g: $HOME/.urxvt/ext/. For the exact path, see the urxvt(1) manual page on perl-lib.

2. In your ~/.Xresources file, add resize-font to the urxvt.perl-ext-common setting so URxvt loads the extension, e.g:

    urxvt.perl-ext-common: default,tabbed,matcher,resize-font,-tabbed
   

Configuration

All configuration of resize-font is done in ~/.Xresources.

Note that this extension requires you to set your font size through the urxvt.font property.

Fonts

Default font sizes can be specified in pixels, using the pixelsize attribute, e.g.:

urxvt.font: xft:Inconsolata:pixelsize=12

Or they can be given in points, using the size attribute, e.g.:

urxvt.font: xft:Inconsolata:size=12

Fixed fonts are also supported, for example:

urxvt.font: 7x14

And, finally, XLFD/X logical font description is supported as well, e.g.:

urxvt.font: -*-inconsolata-medium-*-normal-*-14-*-*-*-*-*-iso8859-*

Keybindings

The default keybindings look like this:

URxvt.keysym.C-minus:     resize-font:smaller
URxvt.keysym.C-plus:      resize-font:bigger
URxvt.keysym.C-equal:     resize-font:reset
URxvt.keysym.C-question:  resize-font:show

Keybindings can be modified using the above syntax. For more information on how to specify keys, see the description of the keysym resource in the urxvt(1) manual page.

Resize interval

You can also configure the number of steps to take when changing the font size:

URxvt.resize-font.step: 2

And even fractions like 0.2 are supported.
