Sublime Move By Symbols

Sublime Text plugin for navigating by symbols of current file up and down.

This is how it works with default settings out of the box.

Installation

Package Control

With Package Control installed:

• Open Command Palette (ctrl + shift + P or ⌘ + ⇧ + P)
• Select Package Control: Install Package (pkginst)
• Search for Move By Symbols (mbsym) package and install it

Manual

Locate Sublime Text Packages directory (Preferences → Browse Packages...) and clone this repository there:

git clone https://github.com/abusalimov/SublimeMoveBySymbols.git "Move By Symbols"

Usage

Two keybindings are provided by default:

            | OSX | Linux / Windows

--------------- | --- | --------------- Previous Symbol | ctrl + up | alt + up Next Symbol | ctrl + down | alt + down

Also a mouse wheel can be used insead of up/down keys, with the same modifiers.

Customization

The main command is move_by_symbols, it takes two boolean arguments:

• forward: bool, mandatory
  Move direction
• extend: bool, default is false
  Controls whether to retain current selection or not

Settings files

All available options are listed below. You can also refer to Preferences → Package Settings → Move By Symbols → Settings – Default to get the list of all settings with their description and fallback defaults.

Options are read in the following order (last match always wins):

• Package settings
• Sublime settings
• Command arguments

Package settings

These settings have the least priority and can be used to modify options globally. For example, to disable showing a symbol in the status bar, open Packages/User/Move By Symbols.sublime-settings file (Preferences → Package Settings → Move By Symbols → Settings – User), and add:

{
    "show_in_status_bar": false
}

Sublime settings

Sublime settings chain is handled as described in the documentation:

• Packages/User/Preferences.sublime-settings
• Project Settings
• Packages/User/<syntax>.sublime-settings

To avoid global namespace pollution all related settings are specified with MoveBySymbols. prefix.

For example, to modify navigation through Diff files so that only names of changed files are included (without selecting diff sections) and to make file names more conspicuous while navigating, create Packages/User/Diff.sublime-settings file (or open it while editing a diff file with Preferences → Settings – More → Syntax Specific – User) and add these lines:

{
    "MoveBySymbols.symbol_selector": "meta.toc-list.file-name.diff",
    "MoveBySymbols.highlight_style": "fill",
    "MoveBySymbols.highlight_scope": "string"
}

Command arguments

Arguments passed to the move_by_symbols command override everything above.

For example, to add a shortcut (with, say, ctrl modifier) for navigating between classes only, add the following to Packages/User/Default (<platform>).sublime-keymap (Preferences → Key Bindings – User):

[
    { "keys": ["ctrl+alt+up"],   "command": "move_by_symbols",
            "args": {"forward": false, "symbol_selector": "entity.name.type"}},
    { "keys": ["ctrl+alt+down"], "command": "move_by_symbols",
            "args": {"forward": true,  "symbol_selector": "entity.name.type"}}
]

Available settings

The following options contol the package behavior:

• symbol_selector: string, default is null, example value: "entity.name"
  If not specified (default), a symbol index is used (shown by ctrl + R outline). Some syntax bundles (like Python) override symbol selector to get more neat outline by adding extra indentation or list of arguments. However, it is much more convenient to navigate by selecting symbol names (identifiers) only, without a surrounding text. Designed to be customized on a per-syntax basis using MoveBySymbols.symbol_selector setting.

• force_single_selection: bool, default is false
  Setting this option to true discards all selections except the first or last one depending on the direction used.

• show_in_status_bar: bool, default is true
  If a single symbol is selected, show its name in the status bar.

• highlight: bool, default is true
  Highlight symbols while navigating.

• highlight_scope: string, default is null, example value: "string"
  If not specified (default), use a foreground color of the symbol itself. If you want all symbols to be painted with the same color, set this option to the name of the desired scope, for example "string", or "comment".

• highlight_style: one of "outline" or "fill", default is "outline"
  Controls how symbols are highlighted.

• highlight_timeout: int, default is 1500
  Time in milliseconds before highlighting automatically disappears.
