CodeEdit
Inherits: TextEdit < Control < CanvasItem < Node < Object
A multiline text editor designed for editing code.
Description
CodeEdit is a specialized TextEdit designed for editing plain text code files. It has many features commonly found in code editors such as line numbers, line folding, code completion, indent management, and string/comment management.
Note: Regardless of locale, CodeEdit will by default always use left-to-right text direction to correctly display source code.

Signals
breakpoint_toggled(line: int) 🔗
Emitted when a breakpoint is added or removed from a line. If the line is moved via backspace a removed is emitted at the old line.
code_completion_requested() 🔗
Emitted when the user requests code completion. This signal will not be sent if _request_code_completion is overridden or code_completion_enabled is false.
symbol_hovered(symbol: String, line: int, column: int) 🔗
Emitted when the user hovers over a symbol. Unlike Control.mouse_entered, this signal is not emitted immediately, but when the cursor is over the symbol for ProjectSettings.gui/timers/tooltip_delay_sec seconds.
Note: symbol_tooltip_on_hover must be true for this signal to be emitted.
symbol_lookup(symbol: String, line: int, column: int) 🔗
Emitted when the user has clicked on a valid symbol.
symbol_validate(symbol: String) 🔗
Emitted when the user hovers over a symbol. The symbol should be validated and responded to, by calling set_symbol_lookup_word_as_valid.
Note: symbol_lookup_on_click must be true for this signal to be emitted.
Enumerations
enum CodeCompletionKind: 🔗
CodeCompletionKind KIND_CLASS = 0
Marks the option as a class.
CodeCompletionKind KIND_FUNCTION = 1
Marks the option as a function.
CodeCompletionKind KIND_SIGNAL = 2
Marks the option as a Redot signal.
CodeCompletionKind KIND_VARIABLE = 3
Marks the option as a variable.
CodeCompletionKind KIND_MEMBER = 4
Marks the option as a member.
CodeCompletionKind KIND_ENUM = 5
Marks the option as an enum entry.
CodeCompletionKind KIND_CONSTANT = 6

CodeCompletionKind KIND_PLAIN_TEXT = 9
Marks the option as unclassified or plain text.
enum CodeCompletionLocation: 🔗
CodeCompletionLocation LOCATION_LOCAL = 0
The option is local to the location of the code completion query - e.g. a local variable. Subsequent value of location represent options from the outer class, the exact value represent how far they are (in terms of inner classes).
CodeCompletionLocation LOCATION_PARENT_MASK = 256
The option is from the containing class or a parent class, relative to the location of the code completion query. Perform a bitwise OR with the class depth (e.g. 0 for the local class, 1 for the parent, 2 for the grandparent, etc.) to store the depth of an option in the class or a parent class.
CodeCompletionLocation LOCATION_OTHER_USER_CODE = 512
The option is from user code which is not local and not in a derived class (e.g. Autoload Singletons).
CodeCompletionLocation LOCATION_OTHER = 1024
The option is from other engine code, not covered by the other enum constants - e.g. built-in classes.
Property Descriptions
bool auto_brace_completion_enabled = false 🔗
If true, uses auto_brace_completion_pairs to automatically insert the closing brace when the opening brace is inserted by typing or autocompletion. Also automatically removes the closing brace when using backspace on the opening brace.
bool auto_brace_completion_highlight_matching = false 🔗
If true, highlights brace pairs when the caret is on either one, using auto_brace_completion_pairs. If matching, the pairs will be underlined. If a brace is unmatched, it is colored with brace_mismatch_color.
Dictionary auto_brace_completion_pairs = { "\"": "\"", "'": "'", "(": ")", "[": "]", "{": "}" } 🔗
void set_auto_brace_completion_pairs(value: Dictionary)
Dictionary get_auto_brace_completion_pairs()
Sets the brace pairs to be autocompleted. For each entry in the dictionary, the key is the opening brace and the value is the closing brace that matches it. A brace is a String made of symbols. See auto_brace_completion_enabled and auto_brace_completion_highlight_matching.
bool code_completion_enabled = false 🔗
If true, the ProjectSettings.input/ui_text_completion_query action requests code completion. To handle it, see _request_code_completion or code_completion_requested.
Array[String] code_completion_prefixes = [] 🔗
Sets prefixes that will trigger code completion.
Array[String] delimiter_comments = [] 🔗
Sets the comment delimiters. All existing comment delimiters will be removed.
Array[String] delimiter_strings = ["' '", "\" \""] 🔗
Sets the string delimiters. All existing string delimiters will be removed.
bool gutters_draw_bookmarks = false 🔗
If true, bookmarks are drawn in the gutter. This gutter is shared with breakpoints and executing lines. See set_line_as_bookmarked.
bool gutters_draw_breakpoints_gutter = false 🔗
If true, breakpoints are drawn in the gutter. This gutter is shared with bookmarks and executing lines. Clicking the gutter will toggle the breakpoint for the line, see set_line_as_breakpoint.
bool gutters_draw_executing_lines = false 🔗
If true, executing lines are marked in the gutter. This gutter is shared with breakpoints and bookmarks. See set_line_as_executing.
bool gutters_draw_fold_gutter = false 🔗
If true, the fold gutter is drawn. In this gutter, the can_fold_code_region icon is drawn for each foldable line (see can_fold_line) and the folded_code_region icon is drawn for each folded line (see is_line_folded). These icons can be clicked to toggle the fold state, see toggle_foldable_line. line_folding must be true to show icons.
bool gutters_draw_line_numbers = false 🔗
If true, the line number gutter is drawn. Line numbers start at 1 and are incremented for each line of text. Clicking and dragging in the line number gutter will select entire lines of text.
bool gutters_zero_pad_line_numbers = false 🔗
If true, line numbers drawn in the gutter are zero padded based on the total line count. Requires gutters_draw_line_numbers to be set to true.
bool indent_automatic = false 🔗
If true, an extra indent is automatically inserted when a new line is added and a prefix in indent_automatic_prefixes is found. If a brace pair opening key is found, the matching closing brace will be moved to another new line (see auto_brace_completion_pairs).
Array[String] indent_automatic_prefixes = [":", "{", "[", "("] 🔗
Prefixes to trigger an automatic indent. Used when indent_automatic is set to true.
