Customizing

Icons

Registering an icon

In xlsd, icons are registered using a name. The name is then used by the different rules to get an icon for an os.DirEntry.

You can view the built-in icons in xlsd/icons.py.

Here is how to add an icon (for example a rainbow). Put this in your .xonshrc

import xlsd.icons

xlsd.icons.LS_ICONS.add('rainbow', "🌈")

Icon sources can now use your fancy icon.

You can also override built-in icons this way.

Extension based icon source

The extension based rules are the fastest to run, and thus are the prefered way of setting icons.

For example, to use your previously defined rainbow icon as the icon for .txt files, you can add the following snippet in your .xonshrc:

import xlsd.icons

xlsd.icons.EXTENSION_ICONS.insert(0, ({'txt'}, 'rainbow'))

Libmagic based icon source

IMPORTANT NOTE: This source seems to only work on Arch Linux systems at the moment.

The libmagic (used by the file command on *nix) based rules are slower, but allow getting an icon when no extension matched.

For example, here we're going to use the xonsh icon for all folders. Add the following snippet in your .xonshrc:

import xlsd.icons

xlsd.icons.MIMETYPE_ICONS.insert(0, ("inode/directory", 'xonsh'))

Note that this won't work unless you set the icon source order with libmagic as the first source, since the extension source already defines an icon for directory entries.

Creating a custom icon source and changing the order

The following snipped registers a new icon source (that simply returns the xonsh icon for everything), and makes it the first checked source. Put this in your .xonshrc.

@xlsd_register_icon_source('my_source')
def my_icon_source(direntry):
    return 'xonsh'

$XLSD_ICON_SOURCES = ['my_source', 'extension', 'libmagic']

File order

Setting the file order

In your .xonshrc, define a $XLSD_SORT_METHOD environment variable with one of the following values:

  • "directories_first": The default: alphabetical order, with directories first
  • "alphabetical": Simple alphabetical order
  • "as_is": The default order of your OS.

Creating your own sort function

You can create a simple alphabetical (case sensitive) sort function with the snippet:

import xlsd

@xlsd.xlsd_register_sort_method('alpha_case_sensitive')
def my_sort_method(entries):
    entries.sort(key=lambda e: e.name)
    return entries

-l mode columns

Changing the columns/the order

In your .xonshrc, define a $XLSD_LIST_COLUMNS environment variable and set it's value to your desires.

The default value (similar to coreutil's ls) is the following:

$XLSD_LIST_COLUMNS = ['mode', 'hardlinks', 'uid', 'gid', 'size', 'mtime', 'name']

All the built-in columns are used in this config.

Writing your own column

A column is a function taking for only argument an os.DirEntry and that outputs a string.

A simple filename column could be registered like this:

@xlsd_register_column('filename', ColumnAlignment.LEFT)
def _xlsd_column_filename(direntry):
    return direntry.name

Colors

There are multiple colors/text effects that you can change in xlsd.

The full list of used colors is available in xlsd/__init__.py.

Here is a small example: we're going to make the size unit in -l mode appear red.

import xlsd

xlsd.COLORS['size_unit'] = '{INTENSE_RED}'

You can use any valid xonsh color.
