Filtile

This is a layout manager for the River window manager. It's a drop-in replacement for rivertile, but with a few things added and configuration per tag/output.

Getting Started

After you install, you can simply replace all instances of rivertile with filtile in your config to keep everything the same (but switch to per-tag configuration). If you want more than that, keep reading.

Usage

All numbers will set the value, but also support a prefix of either + or - for adjustment.

Following are the commands that can be sent to riverctl send-layout-cmd filtile ...:

view-padding [pixels]

Set the padding around views in pixels.

outer-padding [pixels]

Set the padding around the edge of the layout area in pixels.

main-location [left | top | right | bottom]

Set the location of the main area in the layout.

main-count [count]

Set the number of views in the main area of the layout.

main-ratio [percent]

Set the ratio of the main area to total layout area, in percent. The ratio must be between 10 and 90, inclusive.

flip

Flip the main area to the other side of the layout.

pad

Toggle single stack padding. When only one stack is visible, it will be centered and given as much width/height as it would have if there were more windows. Also supports sending "on" or "off" to not toggle.

monocle

Toggle the "monocle" layout. Also supports sending "on" or "off" to not toggle.

smart-padding [pixels]

The padding to apply when there is only one window (and no monocle).

smart-padding off

Turn off smart padding.

smart-padding-h [pixels]

The horizontal (left and right) padding to apply when there is only one window (and no monocle).

smart-padding-v [pixels]

The vertical (top and bottom) padding to apply when there is only one window (and no monocle).

move-split-[up|down|left|right] [percent]

A different way to think about the main ratio. "move-split-right", for example, will make the main-ratio larger when the main-location is left, smaller when it's right, and is a no op for top and bottom.

All commands can be prefaced with one or both of the following options. Either can be "all". Both set to "all" changes the default.

--output

The output (monitor) to apply this setting to.

--tags

The tags to apply this setting to.

Commands can also be sent to the executable on startup, separated by commas, as shown below.

Examples

riverctl map normal Super LEFT send-layout-cmd filtile "move-split-left 5"
riverctl map normal Super RIGHT send-layout-cmd filtile "move-split-right 5"

riverctl map normal Super Z send-layout-cmd filtile "flip"
riverctl map normal Super C send-layout-cmd filtile "pad"

# Set the default layout generator to be filtile and start it.
riverctl default-layout filtile

# - Smart gaps on the sides of every tag (on the larger monitor), to keep
#   single windows from being gigantic.
#
# - A scratch pad on tag 7 with pad (to keep the first window from resizing
#   a bunch) and giant gaps for bling. 
#
# - Tag 1 usually has a browser, which is usually easier to read when it's on
#   the right.
