It also aims to be: - Lightweight - Cross-platform - supports Linux, Windows, and macOS In addition to these things, bottom also currently has the following features: ### Process filtering On any process widget, hit `/` to bring up a search bar. If your layout has multiple process widgets, note this search is independent of other widgets. Searching supports regex, matching case, and matching entire words. Use `Tab` to toggle between searching by PID and by process name. ### Zoom Using the +/- keys or the scroll wheel will move adjust the current time intervals of the currently selected widget. Widgets can hold different time intervals independently. ### Maximizing Only care about the CPU widget right now? Then go to the widget and hit `Enter` to make it take up the entire drawing area. ### Config files bottom supports reading from a config file to customize its behaviour and look. By default, bottom will look at `~/.config/bottom/bottom.toml` or `C:\Users\\AppData\Roaming\bottom\bottom.toml` on Unix and Windows systems respectively. Note that if a config file does not exist at either the default location or the passed in location via `-C` or `--config`, one is automatically created with no settings applied. #### Config flags The following options can be set under `[flags]` to achieve the same effect as passing in a flag on runtime. Note that if a flag is given, it will override the config file. These are the following supported flag config values: | Field | Type | |------------------------|---------------------------------------------------------------------------------------| | `avg_cpu` | Boolean | | `dot_marker` | Boolean | | `left_legend` | Boolean | | `current_usage` | Boolean | | `group_processes` | Boolean | | `case_sensitive` | Boolean | | `whole_word` | Boolean | | `regex` | Boolean | | `show_disabled_data` | Boolean | | `basic` | Boolean | | `rate` | Unsigned Int (represents milliseconds) | | `default_time_value` | Unsigned Int (represents milliseconds) | | `time_delta` | Unsigned Int (represents milliseconds) | | `temperature_type` | String (one of ["k", "f", "c", "kelvin", "fahrenheit", "celsius"]) | | `default_widget_type` | String (one of ["cpu", "proc", "net", "temp", "mem", "disk"], same as layout options) | | `default_widget_count` | Unsigned Int (represents which `default_widget_type`) | #### Theming The config file can be used to set custom colours for parts of the application under the `[colors]` object. The following labels are customizable with strings that are hex colours, RGB colours, or specific named colours. Supported named colours are one of the following strings: `Reset, Black, Red, Green, Yellow, Blue, Magenta, Cyan, Gray, DarkGray, LightRed, LightGreen, LightYellow, LightBlue, LightMagenta, LightCyan, White`. | Labels | Details | Example | | ------------------------------- | ---------------------------------------------- | ------------------------------------------------------- | | Table header colours | Colour of table headers | `table_header_color="255, 255, 255"` | | CPU colour per core | Colour of each core. Read in order. | `cpu_core_colors=["#ffffff", "white", "255, 255, 255"]` | | Average CPU colour | The average CPU color | `avg_cpu_color="White"` | | RAM | The colour RAM will use | `ram_color="#ffffff"` | | SWAP | The colour SWAP will use | `swap_color="#ffffff"` | | RX | The colour rx will use | `rx_color="#ffffff"` | | TX | The colour tx will use | `tx_color="#ffffff"` | | Widget title colour | The colour of the label each widget has | `widget_title_color="#ffffff"` | | Border colour | The colour of the border of unselected widgets | `border_color="#ffffff"` | | Selected border colour | The colour of the border of selected widgets | `highlighted_border_color="#ffffff"` | | Text colour | The colour of most text | `text_color="#ffffff"` | | Graph colour | The colour of the lines and text of the graph | `graph_color="#ffffff"` | | Cursor colour | The cursor's colour | `cursor_color="#ffffff"` | | Selected text colour | The colour of text that is selected | `scroll_entry_text_color="#ffffff"` | | Selected text background colour | The background colour of text that is selected | `scroll_entry_bg_color="#ffffff"` | #### Layout bottom supports customizable layouts via the config file. Currently, layouts are controlled by using TOML objects and arrays. For example, given the sample layout: ```toml [[row]] [[row.child]] type="cpu" [[row]] ratio=2 [[row.child]] ratio=4 type="mem" [[row.child]] ratio=3 [[row.child.child]] type="temp" [[row.child.child]] type="disk" ``` This would give a layout that has two rows, with a 1:2 ratio. The first row has only the CPU widget. The second row is split into two columns with a 4:3 ratio. The first column contains the memory widget. The second column is split into two rows with a 1:1 ratio. The first is the temperature widget, the second is the disk widget. This is what the layout would look like when run: ![Sample layout.](assets/sample_layout.png) Each `[[row]]` represents a _row_ in the layout. A row can have any number of `child` values. Each `[[row.child]]` represents either a _column or a widget_. A column can have any number of `child` values as well. Each `[[row.child.child]]` represents a _widget_. A widget is represented by having a `type` field set to a string. The following `type` values are supported: | | | |---------|--------------------------| | `cpu` | CPU chart and legend | | `mem` | Memory chart | | `proc` | Process table and search | | `net` | Network chart and legend | | `temp` | Temperature table | | `disk` | Disk table | | `empty` | An empty space | Each component of the layout accepts a `ratio` value. If this is not set, it defaults to 1. For an example, look at the [default config](./sample_configs/default_config.toml), which contains the default layout. ...and yes, you can have duplicate widgets. This means you could do something like: ```toml [[row]] ratio=1 [[row.child]] type="cpu" [[row.child]] type="cpu" [[row.child]] type="cpu" [[row]] ratio=1 [[row.child]] type="cpu" [[row.child]] type="empty" [[row.child]] type="cpu" [[row]] ratio=1 [[row.child]] type="cpu" [[row.child]] type="cpu" [[row.child]] type="cpu" ``` and get the following CPU donut: ![CPU donut](./assets/cpu_layout.png) ### Compatibility | OS | CPU | Memory | Disks | Temperature | Processes/Search | Networks | | ------- | --- | ------ | ----- | ----------- | ---------------- | -------- | | Linux | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ | | Windows | ✓ | ✓ | ✓ | ✗ | ✓ | ✓ | | macOS | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ | ## Contributors Contribution is always welcome - just submit a PR!

## Thanks - This project is very much inspired by both [gotop](https://github.com/cjbassi/gotop) and [gtop](https://github.com/aksakalli/gtop). - Basic mode is heavily inspired by [htop's](https://hisham.hm/htop/) design. - This application was written with many, _many_ libraries, and built on the work of many talented people. This application would be impossible without their work.
