# Essential: 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 {TextEditorElement}
|
|
# 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.

|
# highlight will be

# or tail of the given `TextEditorMarker`.
|
|

|
|
#
|
|
# * `marker` A {TextEditorMarker} you want this decoration to follow.
|
|
# * `decorationParams` An {Object} representing the decoration e.g.
|
|
# `{type: 'line-number', class: 'linter-error'}`
|
|
# * `type` There are several supported decoration types. The behavior of the

|
# * `line` Adds the given `class` to the lines overlapping the rows
|
|
# spanned by the `TextEditorMarker`.
|
|
# * `line-number` Adds the given `class` to the line numbers overlapping
|
|
# the rows spanned by the `TextEditorMarker`.
|
|
# * `highlight` Creates a `.highlight` div with the nested class with up
|
|
# to 3 nested regions that fill the area spanned by the `TextEditorMarker`.
|
|
# * `overlay` Positions the view associated with the given item at the
|
|
# head or tail of the given `TextEditorMarker`, depending on the `position`
|
|
# property.
|
|
# * `gutter` Tracks a {TextEditorMarker} in a {Gutter}. Created by calling
|
|
# {Gutter::decorateMarker} on the desired `Gutter` instance.
|
|
# * `block` Positions the view associated with the given item before or
|
|
# after the row of the given `TextEditorMarker`, depending on the `position`
|
|
# property.
|
|
# * `class` This CSS class will be applied to the decorated line number,
|
|
# line, highlight, or overlay.
|
|
# * `item` (optional) An {HTMLElement} or a model {Object} with a
|
|
# corresponding view registered. Only applicable to the `gutter`,
|
|
# `overlay` and `block` types.
|
|
# * `onlyHead` (optional) If `true`, the decoration will only be applied to
|
|
# the head of the `TextEditorMarker`. Only applicable to the `line` and
|
|
# `line-number` types.
|
|
# * `onlyEmpty` (optional) If `true`, the decoration will only be applied if
|
|
# the associated `TextEditorMarker` is empty. Only applicable to the `gutter`,
|
|
# `line`, and `line-number` types.
|
|
# * `onlyNonEmpty` (optional) If `true`, the decoration will only be applied
|
|
# if the associated `TextEditorMarker` is non-empty. Only applicable to the
|
|
# `gutter`, `line`, and `line-number` types.
|
|
# * `position` (optional) Only applicable to decorations of type `overlay` and `block`,
|
|
# controls where the view is positioned relative to the `TextEditorMarker`.
|
|
# Values can be `'head'` (the default) or `'tail'` for overlay decorations, and
|
|
# `'before'` (the default) or `'after'` for block decorations.
