My URxvt configuration includes dynamic font settings for each F-key. With XFT fonts, I'm getting a very wide letter-spacing. I do not want to use the letterSpacing setting because my other font settings are not XFT, so spacing is fine. I toggle between fonts regularly with my F-keys.
Is there a way to dynamically set the letterSpacing setting in urxvt?
That is letterSpace, which can be queried and set via the perl interface.
The documentation lists several resources which can be treated this way:
$value = $term->resource ($name[, $newval]) Returns the current resource value associated with a given name and optionally sets a new value. Setting values is most useful in the "init" hook. Unset resources are returned and accepted as "undef". The new value must be properly encoded to a suitable character encoding before passing it to this method. Similarly, the returned value may need to be converted from the used encoding to text. Resource names are as defined in src/rsinc.h. Colours can be specified as resource names of the form "color+", e.g. "color+5". (will likely change). Please note that resource strings will currently only be freed when the terminal is destroyed, so changing options frequently will eat memory. Here is a likely non-exhaustive list of resource names, not all of which are supported in every build, please see the source file /src/rsinc.h to see the actual list: answerbackstring backgroundPixmap backspace_key blurradius boldFont boldItalicFont borderLess buffered chdir color cursorBlink cursorUnderline cutchars delete_key depth display_name embed ext_bwidth fade font geometry hold iconName iconfile imFont imLocale inputMethod insecure int_bwidth intensityStyles iso14755 iso14755_52 italicFont jumpScroll letterSpace lineSpace loginShell mapAlert meta8 modifier mouseWheelScrollPage name override_redirect pastableTabs path perl_eval perl_ext_1 perl_ext_2 perl_lib pointerBlank pointerBlankDelay preeditType print_pipe pty_fd reverseVideo saveLines scrollBar scrollBar_align scrollBar_floating scrollBar_right scrollBar_thickness scrollTtyKeypress scrollTtyOutput scrollWithBuffer scrollstyle secondaryScreen secondaryScroll shade skipBuiltinGlyphs skipScroll term_name title transient_for transparent tripleclickwords urgentOnBell utmpInhibit visualBell
