# Authoring Themes
|
||||
|
||||
If you understand CSS, you can write an Atom theme easily. Your theme can style
|
||||
Atom's user interface, specify the appearance of syntax-highlighted code, or
|
||||
both. For making a syntax highlighting theme, refer to
|
||||
[section 12.4 of the TextMate Manual](http://manual.macromates.com/en/language_grammars.html)
|
||||
for a list of the common scopes used by TextMate grammars. You'll just need to
|
||||
translate scope names to CSS classes. To theme Atom's user interface, take a
|
||||
look at the existing light and dark themes for an example. Pressing `alt-meta-i`
|
||||
and inspecting the Atom's markup directly can also be helpful.
|
||||
|
||||
The most basic theme is just a _.css_ file. More complex themes occupy their own
|
||||
folder, which can contain multiple stylesheets along with an optional
|
||||
_package.cson_ file containing a manifest to control their load-order:
|
||||
|
||||
```text
|
||||
~/.atom/themes/
|
||||
rockstar.css
|
||||
rainbow/
|
||||
package.json
|
||||
core.css
|
||||
editor.css
|
||||
tree-view.css
|
||||
```
|
||||
|
||||
package.cson:
|
||||
```coffee-script
|
||||
stylesheets: ["core.css", "editor.less", "tree-view.css"]
|
||||
```
|
||||
|
||||
The `package.cson` file specifies which stylesheets to load and in what order
|
||||
with the `stylesheets` key. If no manifest is specified, all stylesheets are
|
||||
loaded in alphabetical order when the user selects the theme.
|
||||
|
||||
|
||||
## Theme Extensions (Not Yet Implemented)
|
||||
|
||||
A theme may need to be extended to cover DOM elements that are introduced by a
|
||||
third-party Atom package. When a package is loaded, stylesheets with the same
|
||||
name as the package will automatically be loaded from the `packages` directory
|
||||
of active themes:
|
||||
|
||||
```text
|
||||
~/.atom/themes/
|
||||
midnight/midnight.less
|
||||
midnight/packages/terminal.less
|
||||
midnight/packages/tree-view.less
|
||||
```
|
||||
|
||||
In the example above, if the `midnight` theme is active, its `terminal` and
|
||||
`tree-view` stylesheets will be loaded automatically if and when those packages
|
||||
are activated. If you author an extension to a theme consider sending its author
|
||||
a pull request to have it included in the theme by default. Package-specific
|
||||
theme stylesheets need not be listed in the theme's `package.json` because they
|
||||
will be loaded automatically when the package is loaded.

commands that are relevant to the currently focused UI element. If there is a

key binding for a given command, it is also displayed. This is a great way to

You can always use `meta-p` to explore available commands and their

bindings, but here's a list of a few useful commands.

- `meta-r` : reload the current window

- `meta-t` : open file finder to navigate files in your project
|

- `meta-;` : open command prompt
|
||||
- `meta-f` : open command prompt with `/` for a local file search
|
||||
- `meta-g` : repeat the last local search
|
||||
- `meta-shift-f` : open command prompt with `Xx/` for a project-wide search
|
||||
- `meta-\` : focus/open tree view, or close it when it is focused
|
||||
- `meta-|` : open tree view with the current file selected
|
||||
- `ctrl-w v`, `ctrl-|` : split screen vertically

### Searching

|

#### Using the Command Line
|
||||
#### Find and Replace
|
||||
|
||||
Atom has a command line similar to old-school editors such as emacs and vim. Nearly
|
||||
every command has a key binding which you can discover with `meta-p`.
|
||||
|
||||
The command line is also (currently) the only place you can perform a search. Hitting
|
||||
`meta-f` opens the command line and prepopulates it with the `/` command. This finds
|
||||
text in the current buffer, starting at the location of the cursor. Pressing `meta-g`
|
||||
repeats the search. Hitting `meta-shift-f` opens the command line and prepopulates
|
||||
it with `Xx/`, which is a composite command that performs a global search. The results
|
||||
of the search appear in the operation preview list, which you can focus
|
||||
with `meta-:`.
|
||||
|
||||
Atom's command language is still under construction, and is loosely based on
|
||||
the [Sam editor](http://doc.cat-v.org/bell_labs/sam_lang_tutorial/) from the
|
||||
Plan 9 operating system. It's similar to Ex mode in vim, but is selection-based
|
||||
rather than line-based. It allows you to compose commands together in
|
||||
interesting ways.

## Customizing Key Bindings
|
||||
|
||||
Atom keymaps work similarly to stylesheets. Just as stylesheets use selectors
|
||||
to apply styles to elements, Atom keymaps use selectors to associate keystrokes
|
||||
with events in specific contexts. Here's a small example, excerpted from Atom's
|
||||
built-in keymaps:
|
||||
|
||||
```coffeescript
|
||||
'.editor':
|
||||
'enter': 'editor:newline'
|
||||
|
||||
'.select-list .editor.mini':
|
||||
'enter': 'core:confirm'
|
||||
```
|
||||
|
||||
This keymap defines the meaning of `enter` in two different contexts. In a
|
||||
normal editor, pressing `enter` emits the `editor:newline` event, which causes
|
||||
the editor to insert a newline. But if the same keystroke occurs inside of a
|
||||
select list's mini-editor, it instead emits the `core:confirm` event based on
|
||||
the binding in the more-specific selector.
|
||||
|
||||
By default, any keymap files in your `~/.atom/keymaps` directory will be loaded
|
||||
in alphabetical order when Atom is started. They will always be loaded last,
|
||||
giving you the chance to override bindings that are defined by Atom's core
|
||||
keymaps or third-party packages.
|
||||
|
||||
## Changing The Theme
|
||||
|
||||
Atom comes bundles with two themes `atom-dark-*` and `atom-light-*`.
|
||||
|
||||
Because Atom themes are based on CSS, it's possible to have multiple themes
|
||||
active at the same time. For example, you'll usually select a theme for the UI
|
||||
and another theme for syntax highlighting. You can select themes by specifying
|
||||
them in the `core.themes` array in your `config.cson`:
|
||||
|
||||
```coffeescript
|
||||
core:
|
||||
themes: ["atom-light-ui", "atom-light-syntax"]
|
||||
# or, if the sun is going down:
|
||||
# themes: ["atom-dark-ui", "atom-dark-syntax"]
|
||||
```
|
||||
|
||||
You install new themes by placing them in the `~/.atom/themes` directory. A
|
||||
theme can be a CSS file, a directory containing multiple CSS files, or a
|
||||
TextMate theme (either `.tmTheme` or `.plist`).
|
||||
|
||||
|
||||
## Installing Packages (Partially Implemented)
|
||||
|
||||
To install a package, clone it into the `~/.atom/packages` directory. Atom will
|
||||
also load grammars and snippets from TextMate bundles. If you want to disable a
|
||||
package without removing it from the packages directory, insert its name into
|
||||
`config.core.disabledPackages`:
|
||||
|
||||
config.cson:
|
||||
```coffeescript
|
||||
core:
|
||||
disabledPackages: [
|
||||
"fuzzy-finder",
|
||||
"tree-view"
|
||||
]
|
||||
```
|
||||
|
||||
## Quick Personal Hacks
|
||||
|
||||
### user.coffee
|
||||
|
||||
When Atom finishes loading, it will evaluate `user.coffee` in your `~/.atom`
|
||||
directory, giving you a chance to run arbitrary personal CoffeeScript code to
|
||||
make customizations. You have full access to Atom's API from code in this file.
|
||||
Please refer to the Atom Internals Guide for more information. If your
|
||||
customizations become extensive, consider creating a package.
|
||||
|
||||
### user.css
|
||||
|
||||
If you want to apply quick-and-dirty personal styling changes without creating
|
||||
an entire theme that you intend to distribute, you can add styles to
|
||||
`user.css` in your `~/.atom` directory.
|
||||
|
||||
For example to change the color of the highlighted line number for the line that
|
||||
contains the cursor, you could add the following style to `user.css`:
|
||||
|
||||
```css
|
||||
.editor .line-number.cursor-line {
|
||||
color: pink;
|
||||
}
|
||||
```
