Example using btm --dot_marker Another (better) alternative is to install a font that supports braille fonts, and configure your terminal emulator to use it. For example, installing something like UBraille or Iosevka and ensuring your terminal uses it should work.

This section is in progress, and is just copied from the old documentation.
You can hide specific disks, temperature sensors, and networks by name in the config file via disk_filter and mount_filter, temp_filter, and net_filter respectively. Regex (regex = true), case-sensitivity (case_sensitive = true), and matching only if the entire word matches (whole_word = true) are supported, but are off by default. Filters default to denying entries that match and can be toggled by setting is_list_ignored to false in the config file.
For example, here's the disk widget with no filter:
The following in the config file would filter out some entries by disk name:
[disk_filter]\nis_list_ignored = true\nlist = [\"/dev/sda\"]\nregex = true\ncase_sensitive = false\nwhole_word = false\n
If there are two potentially conflicting filters (i.e. when you are using both a disk and mount filter), the filter that explicitly allows an entry takes precedence over a filter that explicitly denies one. So for example, let's say we set a disk filter accepting anything with /dev/sda, but deny anything with /mnt/.* or /. So to do so, we write in the config file:
[disk_filter]\nis_list_ignored = false\nlist = [\"/dev/sda\"]\nregex = true\ncase_sensitive = false\nwhole_word = false\n\n[mount_filter]\nis_list_ignored = true\nlist = [\"/mnt/.*\", \"/\"]\nregex = true\ncase_sensitive = false\nwhole_word = true\n

This section is in progress, and is just copied from the old documentation.
bottom supports customizable layouts via the config file. Currently, layouts are controlled by using TOML objects and arrays.
For example, given the sample layout:
[[row]]\n [[row.child]]\n type=\"cpu\"\n[[row]]\n ratio=2\n [[row.child]]\n ratio=4\n type=\"mem\"\n [[row.child]]\n ratio=3\n [[row.child.child]]\n type=\"temp\"\n [[row.child.child]]\n type=\"disk\"\n
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:
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\" Memory chart \"net\", \"network\" Network chart and legend \"proc\", \"process\", \"processes\" Process table and search \"temp\", \"temperature\" Temperature table \"disk\" Disk table \"empty\" An empty space \"batt\", \"battery\" Battery statistics Each component of the layout accepts a ratio value. If this is not set, it defaults to 1.
Furthermore, you can have duplicate widgets.
For an example, look at the default config, which contains the default layout.

Where you're adding documentation will probably affect what you need to do:
README.md or CHANGELOG.md For changes to README.md and CHANGELOG.md, just follow the formatting provided and use any editor.
Generally, changes to CHANGELOG.md will be handled by a maintainer, and the contents of the file should follow the Keep a Changelog format, as well as link to the relevant PR or issues.
Help menu For changes to the help menu, try to refer to the existing code within src/constants.rs on how the help menu is generated.
Extended documentation For changes to the extended documentation, you'll probably want at least Python 3.11 (older and newer versions should be fine), MkDocs, Material for MkDocs, mdx_truly_sane_lists, and optionally Mike installed. These can help with validating your changes locally.
You can do so through pip or your system's package managers. If you use pip, you can use venv to cleanly install the documentation dependencies:
# Change directories to the documentation.\ncd docs/\n\n # Create venv, install the dependencies, and serve the page.\n./serve.sh\n
This will serve a local version of the docs that you can open on your browser. It will update as you make changes.

If you want to generate manpages and/or completion files, set the BTM_GENERATE env var to a non-empty value. For example, run something like this:
BTM_GENERATE=true cargo build --release --locked\n
This will automatically generate completion and manpage files in target/tmp/bottom/. If you wish to regenerate the files, modify/delete either these files or set BTM_GENERATE to some other non-empty value to retrigger the build script.
For more information, you may want to look at either the build.rs file or the binary build CI workflow.

- Binaries for various platforms
- MSI installer for Windows
.deb package for Debian and its derivatives
This documentation gives a high-level overview of the build process for each part. For the most up-to-date and detailed reference, definitely refer back to the build_releases.yml file.

The following env variables set:
BTM_GENERATE: trueCOMPLETION_DIR: \"target/tmp/bottom/completion/\"MANPAGE_DIR: \"target/tmp/bottom/manpage/\"

Stable: a stable deployment, triggered manually or upon creation of a valid tag. This is a GitHub action that builds binary/installer files and uploads them to a new GitHub release.

Win+R and opening regedit, or just opening it from the Start Menu. -
In the registry editor, go to

This section is in progress, and is just copied from the old documentation.
You can hide specific disks, temperature sensors, and networks by name in the config file via disk_filter and mount_filter, temp_filter, and net_filter respectively. Regex (regex = true), case-sensitivity (case_sensitive = true), and matching only if the entire word matches (whole_word = true) are supported, but are off by default. Filters default to denying entries that match and can be toggled by setting is_list_ignored to false in the config file.
For example, here's the disk widget with no filter:
The following in the config file would filter out some entries by disk name:
[disk_filter]\nis_list_ignored = true\nlist = [\"/dev/sda\"]\nregex = true\ncase_sensitive = false\nwhole_word = false\n
If there are two potentially conflicting filters (i.e. when you are using both a disk and mount filter), the filter that explicitly allows an entry takes precedence over a filter that explicitly denies one. So for example, let's say we set a disk filter accepting anything with /dev/sda, but deny anything with /mnt/.* or /. So to do so, we write in the config file:
[disk_filter]\nis_list_ignored = false\nlist = [\"/dev/sda\"]\nregex = true\ncase_sensitive = false\nwhole_word = false\n\n[mount_filter]\nis_list_ignored = true\nlist = [\"/mnt/.*\", \"/\"]\nregex = true\ncase_sensitive = false\nwhole_word = true\n

This section is in progress, and is just copied from the old documentation.
bottom supports customizable layouts via the config file. Currently, layouts are controlled by using TOML objects and arrays.
For example, given the sample layout:
[[row]]\n [[row.child]]\n type=\"cpu\"\n[[row]]\n ratio=2\n [[row.child]]\n ratio=4\n type=\"mem\"\n [[row.child]]\n ratio=3\n [[row.child.child]]\n type=\"temp\"\n [[row.child.child]]\n type=\"disk\"\n
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:
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\" Memory chart \"net\", \"network\" Network chart and legend \"proc\", \"process\", \"processes\" Process table and search \"temp\", \"temperature\" Temperature table \"disk\" Disk table \"empty\" An empty space \"batt\", \"battery\" Battery statistics Each component of the layout accepts a ratio value. If this is not set, it defaults to 1.
Furthermore, you can have duplicate widgets.
For an example, look at the default config, which contains the default layout.

Where you're adding documentation will probably affect what you need to do:
README.md or CHANGELOG.md For changes to README.md and CHANGELOG.md, just follow the formatting provided and use any editor.
Generally, changes to CHANGELOG.md will be handled by a maintainer, and the contents of the file should follow the Keep a Changelog format, as well as link to the relevant PR or issues.
Help menu For changes to the help menu, try to refer to the existing code within src/constants.rs on how the help menu is generated.
Extended documentation For changes to the extended documentation, you'll probably want at least Python 3.11 (older and newer versions should be fine), MkDocs, Material for MkDocs, mdx_truly_sane_lists, and optionally Mike installed. These can help with validating your changes locally.
You can do so through pip or your system's package managers. If you use pip, you can use venv to cleanly install the documentation dependencies:
# Change directories to the documentation.\ncd docs/\n\n # Create venv, install the dependencies, and serve the page.\n./serve.sh\n
This will serve a local version of the docs that you can open on your browser. It will update as you make changes.
