  • With cargo installed, one option would be to move the the binary to $HOME/.cargo/bin

CLI

Starting in version 2.0.0, river-bsp-layout allows the padding of each inner and outer edge to be set independently of the other edges. This allows for more diverse configurations, such as featured in the Examples Section.

CLI Help

Usage: river-bsp-layout [OPTIONS]

Options:
  -i, --inner-gap <DEFAULT_INNER_GAP>  The number of pixels to pad each inner edge of a window by default [default: 0]
  -l, --ig-left <IG_LEFT>              The number of pixels to pad the left inner edge of each window. This Overrides `default_inner_gap`. Optional
  -r, --ig-right <IG_RIGHT>            The number of pixels to pad the right inner edge of each window. This Overrides `default_inner_gap`. Optional
  -b, --ig-bottom <IG_BOTTOM>          The number of pixels to pad the bottom inner edge of each window. This Overrides `default_inner_gap`. Optional
  -t, --ig-top <IG_TOP>                The number of pixels to pad the top inner edge of each window. This Overrides `default_inner_gap`. Optional
  -o, --outer-gap <DEFAULT_OUTER_GAP>  The default size of the gap between windows and the edge of the screen [default: 0]
  -L, --og-left <OG_LEFT>              The number of pixels to place between the left screen edge and any windows. Overrides `default_outer_gap` for the left side. Optional
  -R, --og-right <OG_RIGHT>            The number of pixels to place between the right screen edge and any windows. Overrides `default_outer_gap` for the right side. Optional
  -B, --og-bottom <OG_BOTTOM>          The number of pixels to place between the bottom screen edge and any windows. Overrides `default_outer_gap` for the bottom side. Optional
  -T, --og-top <OG_TOP>                The number of pixels to place between the top screen edge and any windows. Overrides `default_outer_gap` for the top side. Optional
  -h, --help                           Print help
  -V, --version                        Print version

CLI Examples

In this configuration, all inner gaps are set to 5 pixels, and all outer gaps are set to 10, except the top gap, which is 0, so top windows sit flush with the bar.

This config can be achieved with the following invocation

river-bsp-layout --inner-gap 5 --outer-gap 10 --og-top 0

This config features uniform outer gaps of 10 pixels and inner gaps of 5 pixels on each edge.

river-bsp-layout --inner-gap 5 --outer-gap 10

This config is mostly to demonstrate the possibilities of individually configurable edge gaps.

river-bsp-layout --ig-top 1 --og-bottom 5 --ig-right 10 --og-left 15 --og-top 20 --ig-bottom 25 --og-right 30 --ig-left 35

• riverctl send-layout-cmd bsp-layout outer-gap # - Sets all outer gaps to #
• riverctl send-layout-cmd bsp-layout og-left # - Set only the left outer gap to #
• riverctl send-layout-cmd bsp-layout og-right # - Set only the right outer gap to #
• riverctl send-layout-cmd bsp-layout og-bottom # - Set only the bottom outer gap to #
• riverctl send-layout-cmd bsp-layout og-top # - Set only the top outer gap to #
• riverctl send-layout-cmd bsp-layout inner-gap # - Sets all inner gaps to #
• riverctl send-layout-cmd bsp-layout ig-left # - Set only the left inner gap to #
• riverctl send-layout-cmd bsp-layout ig-right # - Set only the right inner gap to #
• riverctl send-layout-cmd bsp-layout ig-bottom # - Set only the bottom inner gap to #
• riverctl send-layout-cmd bsp-layout ig-top # - Set only the top inner gap to #

Starting from River init

Assuming you are using a default bash init script, replace the following lines at the end of the file

riverctl default-layout rivertile
rivertile -view-padding 6 -outer-padding 6 &

with

riverctl default-layout bsp-layout
river-bsp-layout --inner-gap 5 --outer-gap 10 &
