layout-machi

A manual layout for Awesome with a rapid interactive editor.

Why?

TL;DR --- I want the control of my layout.

1. Dynamic tiling is an overkill, since tiling is only useful for persistent windows, and people extensively use hibernate/sleep these days.
2. I don't want to have all windows moving around whenever a new window shows up.
3. I want to have a flexible layout such that I can quickly adjust to whatever I need.

Use the layout

Use layout_machi.layout.create_layout([LAYOUT_NAME}, [DEFAULT_REGIONS]) to instantiate the layout. For example:

layout_machi.layout.create_layout("default", {})

Creates a layout with no regions

Use the editor

Call layout_machi.editor.start_editor(data) to enter the editor for the current layout (given it is a machi instance). data is am object for storing the history of the editing, initially {}. The editor starts with the open area of the entire workarea, taking command to split the current area into multiple sub-areas, then editing each of them. The editor is keyboard driven, accepting a number of command keys. Before each command, you can optionally provide at most 2 digits for parameters (A, B) of the command. Undefined parameters are (mostly) treated as 1.

1. Up/Down: restore to the history command sequence
2. h/v: split the current region horizontally/vertically into 2 regions. The split will respect the ratio A:B.
3. w: Take two parameters (A, B), and split the current region equally into A columns and B rows. If no parameter is defined, behave the same as Space without parameters.
4. s: shift the current editing region with other open regions. If A is defined, shift for A times.
5. Space or -: Without parameters, close the current region and move to the next open region. With parameters, set the maximum depth of splitting (default is 2).
6. Enter/.: close all open regions. When all regions are closed, press Enter will save the layout and exit the editor.
7. Backspace: undo the last command.
8. Escape: exit the editor without saving the layout.

Demos:

I used Super + / for the editor and Super + Tab for fitting the windows.

Details:

• 3-: set the maximum editing depth to 3
• 13h: horizontally split the initial region (entire desktop) to the ratio of 1:3
• For the left part:
  • 2v: vertically split the region to the ratio of 2:1
  • --: ignore further editing the splitted regions
• For the right part:
  • 2h: horizontally split the region to the ratio of 2:1
  • -: ignore the left part of the splitted regions
  • 12v: split the right part vertically to the ratio of 1:2

Tada!

history

Persistent history

You need to specify the path of the history file in the editor data, then restore the persistent history by layout_machi.editor.restore_data. For example,

machi_layout_data = layout_machi.editor.restore_data({ history_file = ".machi-layout", history_save_max = 10 })

Then start the editor with the restored data. The last history_save_max commands are persisted.

Other functions

layout_machi.editor.cycle_region(c) will fit a floating client into the closest region, then cycle through all regions.
