GOUI SourceView

A native code editor for Go applications

中文

GOUI SourceView brings source code editing to GOUI applications, with syntax highlighting, completion, matching brackets, and Modern light/dark appearances. It supports both imperative and declarative integration.

The project is under active development.

Features

  • Syntax highlighting for JSON, XML, HTML, Markdown, TOML, YAML and Shell.
  • Folding and navigation for structured documents, Markdown headings and code fences, with line/column navigation.
  • Editing assistance with smart indentation, whitespace markers, indent guides and rulers.
  • Code editing with Unicode selection, clipboard, undo/redo, indentation and line operations.
  • Completion and brackets with suggestions, automatic pairs, matching-bracket navigation and linked tag names.
  • Custom languages with application-defined highlighting, editing rules and completion.
  • Find and replace in a floating panel, with multiline queries, regular expressions, capture replacements and selection scopes.
  • Light and dark appearances with syntax colors preserved in selections.
  • Multilingual controls with editor menus and find/replace available in eight languages.

Build with an AI coding assistant

The SourceView application development Skill helps your AI integrate the editor and customize highlighting, editing rules, and completion. To install it, tell your AI:

Install the SourceView application development skill following https://github.com/golang-gui/goui-sourceview/blob/main/skills/INSTALL.md.

The installation guide uses your tool's native skill mechanism. Tools without Skill support can read the development guide directly. Installing the Skill does not install or upgrade your application's Go dependencies.

Try the example

Requires Go 1.24 or newer. Follow the example guide to prepare the development environment, then run from the repository root:

go run ./example/editor

The example lets you edit JSON, XML, HTML, Markdown, TOML, YAML and Shell, try search and completion, and switch between light and dark appearances. A declarative example and a custom Markdown editor are also available.

Overview

Package sourceview provides a native GOUI code editor. All widget and document operations are sequential and, while mounted, belong on the GUI thread.

Types

type Command 

type Command uint16

Command identifies an editor operation, not a global command registration. Zero and unknown values are invalid. Bindings do not change an operation's editing, focus, preedit or lifecycle requirements. 

const (
	CommandUndo Command = iota + 1
	CommandRedo
	CommandCut
	CommandCopy
	CommandPaste
	CommandDeleteSelection
	CommandMoveLinesUp
	CommandMoveLinesDown
	CommandDuplicateLinesUp
	CommandDuplicateLinesDown
	CommandDeleteLines
	CommandSelectAll
	CommandFold
	CommandUnfold
	CommandFoldAll
	CommandUnfoldAll
	CommandComplete
	CommandToggleLineComment
	CommandToggleBlockComment
	CommandIndent
	CommandOutdent
	CommandInsertLineAbove
	CommandInsertLineBelow
	CommandSelectLine
	CommandJumpToBracket
	CommandMoveWordLeft
	CommandMoveWordRight
	CommandSelectWordLeft
	CommandSelectWordRight
	CommandDeleteWordLeft
	CommandDeleteWordRight
	CommandMoveLineStart
	CommandMoveLineEnd
	CommandSelectLineStart
	CommandSelectLineEnd
	CommandMoveDocumentStart
	CommandMoveDocumentEnd
	CommandSelectDocumentStart
	CommandSelectDocumentEnd
	CommandFindNext
	CommandFindPrevious
	// Find/Replace/GoTo are handled only by an attached companion bar.
	CommandFind
	CommandReplace
	CommandGoTo
)

type Completion 

type Completion struct {
	Label, Text, Detail string
	Range               *textedit.Range
	AdditionalEdits     []textedit.Edit
	Caret               *int
}

Completion is a literal edit. Nil Range uses the requested word range. Empty Text uses Label. Caret, when set, is a UTF-8 offset relative to inserted Text. AdditionalEdits use the same original document coordinates as the primary edit.

func DefaultCompletions 

func DefaultCompletions(c CompletionContext) []Completion

DefaultCompletions explicitly combines language suggestions and nearby words, with case-insensitive prefix filtering, de-duplication and alphabetical order.

func DocumentCompletions 

func DocumentCompletions(c CompletionContext) []Completion

DocumentCompletions returns whole words from the bounded nearby snapshot.

func LanguageCompletions 

func LanguageCompletions(c CompletionContext) []Completion

LanguageCompletions returns the definition's static suggestions in code context.

type CompletionContext 

type CompletionContext struct {
	DocumentID, Revision         uint64
	Language                     language.ID
	Definition                   *language.Language
	Range                        textedit.Range
	Caret                        int
	Prefix                       string
	Explicit                     bool
	Trigger                      string
	Lexical                      language.Context
	ContextKnown                 bool
	Before, After, NearbyText    string
	NearbyOffset, DocumentLength int
}

CompletionContext is an immutable, bounded snapshot, safe on a worker. It has no live Model, Document or Widget. Offsets are UTF-8 bytes. NearbyText has at most 32 KiB on either side; Before/After have at most 16 KiB of the current line. Language/Definition describe the effective language at the caret, including an explicit embedded language. DocumentID remains the outer document identity.

type CompletionProvider 

type CompletionProvider struct {
	TriggerCharacters string
	Complete          func(context.Context, CompletionContext) ([]Completion, error)
}

CompletionProvider completely owns candidates, filtering and order. Treat this configuration as immutable; reuse its pointer across declarative updates. Complete runs on one worker per view, must honor cancellation, and must not touch GUI objects. Nil provider selects DefaultCompletions. Empty results stay empty. TriggerCharacters allows automatic requests even with an empty prefix.

type Document 

type Document struct {
	// contains filtered or unexported fields
}

func NewDocument 

func NewDocument(text string) *Document

func NewDocumentWithModel 

func NewDocumentWithModel(model *textedit.Model) *Document

	gui.WidgetBase
	// contains filtered or unexported fields
}

FindBar is an optional companion widget. Usually mount it as an Overlay above the editor viewport in the same Root, then SetTarget. It owns its controls, not the editor or document. Its content is initially closed; the application chooses its placement.

func NewFindBar 

func NewFindBar() *FindBar

}

FoldRegion is a detached snapshot. Lines are zero-based and EndLine inclusive.

type GoToBar 

type GoToBar struct {
	gui.WidgetBase
	// contains filtered or unexported fields
}

GoToBar is an optional floating line/column input. Mount it in an Overlay in the editor's Root. It borrows its target and does not own document state.

KeyBindings maps editor commands to alternative single-key gestures. It covers command shortcuts, not text commits or transient popup navigation.

func DefaultKeyBindings 

func DefaultKeyBindings() KeyBindings

DefaultKeyBindings returns a fresh, editable table for the current platform. Explicit completion has no default gesture; applications may bind it.

type SearchQuery 

type SearchQuery struct {
	Text                         string
	IgnoreCase, WholeWord, Regex bool
}

type SourceView 

type SourceView struct {
	gui.WidgetBase
	// contains filtered or unexported fields
