# Public: This class represents all essential editing state for a single
|
|
# {TextBuffer}, including cursor and selection positions, folds, and soft wraps.
|
|
# If you're manipulating the state of an editor, use this class. If you're
|
|
# interested in the visual appearance of editors, use {TextEditorView} instead.
|
|
#
|
|
# A single {TextBuffer} can belong to multiple editors. For example, if the
|
|
# same file is open in two different panes, Atom creates a separate editor for
|
|
# each pane. If the buffer is manipulated the changes are reflected in both
|
|
# editors, but each maintains its own cursor position, folded lines, etc.
|
|
#
|
|
# ## Accessing TextEditor Instances
|
|
#
|
|
# The easiest way to get hold of `TextEditor` objects is by registering a callback
|
|
# with `::observeTextEditors` on the `atom.workspace` global. Your callback will
|
|
# then be called with all current editor instances and also when any editor is
|
|
# created in the future.
|
|
#
|
|
# ```coffee
|
|
# atom.workspace.observeTextEditors (editor) ->
|
|
# editor.insertText('Hello World')
|
|
# ```
|
|
#
|
|
# ## Buffer vs. Screen Coordinates
|
|
#
|
|
# Because editors support folds and soft-wrapping, the lines on screen don't
|
|
# always match the lines in the buffer. For example, a long line that soft wraps
|
|
# twice renders as three lines on screen, but only represents one line in the
|
|
# buffer. Similarly, if rows 5-10 are folded, then row 6 on screen corresponds
|
|
# to row 11 in the buffer.
|
|
#
|
|
# Your choice of coordinates systems will depend on what you're trying to
|
|
# achieve. For example, if you're writing a command that jumps the cursor up or
|
|
# down by 10 lines, you'll want to use screen coordinates because the user
|
|
# probably wants to skip lines *on screen*. However, if you're writing a package
|
|
# that jumps between method definitions, you'll want to work in buffer
|
|
# coordinates.
|
|
#
|
|
# **When in doubt, just default to buffer coordinates**, then experiment with
|
|
# soft wraps and folds to ensure your code interacts with them correctly.

Section: Decorations
|
|
###
|
|
|
|
# Essential: Adds a decoration that tracks a {Marker}. When the marker moves,
|
|
# is invalidated, or is destroyed, the decoration will be updated to reflect
|
|
# the marker's state.
|
|
#
|
|
# There are three types of supported decorations:
|
|
#
|
|
# * __line__: Adds your CSS `class` to the line nodes within the range
|
|
# marked by the marker
|
|
# * __gutter__: Adds your CSS `class` to the line number nodes within the
|
|
# range marked by the marker
|
|
# * __highlight__: Adds a new highlight div to the editor surrounding the
|
|
# range marked by the marker. When the user selects text, the selection is
|
|
# visualized with a highlight decoration internally. The structure of this
|
|
# highlight will be
|
|
# ```html
|
|
# <div class="highlight <your-class>">
|
|
# <!-- Will be one region for each row in the range. Spans 2 lines? There will be 2 regions. -->
|
|
# <div class="region"></div>
|
|
# </div>
|
|
# ```
|
|
#
|
|
# ## Arguments
|
|
#
|
|
# * `marker` A {Marker} you want this decoration to follow.
|
|
# * `decorationParams` An {Object} representing the decoration e.g.
|
|
# `{type: 'line-number', class: 'linter-error'}`
|
|
# * `type` There are a few supported decoration types: `gutter`, `line`,
|
|
# `highlight`, and `overlay`. The behavior of the types are as follows:
|
|
# * `gutter` Adds the given `class` to the line numbers overlapping the
|
|
# rows spanned by the marker.
|
|
# * `line` Adds the given `class` to the lines overlapping the rows
|
|
# spanned by the marker.
|
|
# * `highlight` Creates a `.highlight` div with the nested class with up
|
|
# to 3 nested regions that fill the area spanned by the marker.
|
|
# * `overlay` Positions the view associated with the given item at the
|
|
# head or tail of the given marker, depending on the `position`
|
|
# property.
|
|
# * `class` This CSS class will be applied to the decorated line number,
|
|
# line, or highlight.
|
|
# * `onlyHead` (optional) If `true`, the decoration will only be applied to
|
|
# the head of the marker. Only applicable to the `line` and `gutter`
|
|
# types.
|
|
# * `onlyEmpty` (optional) If `true`, the decoration will only be applied if
|
|
# the associated marker is empty. Only applicable to the `line` and
|
|
# `gutter` types.
|
|
# * `onlyNonEmpty` (optional) If `true`, the decoration will only be applied
|
|
# if the associated marker is non-empty. Only applicable to the `line`
|
|
# and gutter types.
|
|
# * `position` (optional) Only applicable to decorations of type `overlay`,
|
|
# controls where the overlay view is positioned relative to the marker.
|
|
# Values can be `'head'` (the default), or `'tail'`.
|
|
# * `gutterName` (optional) Only applicable to the `gutter` type. If provided,
|
|
# the decoration will be applied to the gutter with the specified name.
|
|
#
|
|
# Returns a {Decoration} object
