Overview

The backend package defines the very soul of Lime.

Some highlevel concepts follow.

Frontend

Lime is designed with the goal of having a clear frontend and backend separation to allow and hopefully simplify the creation of multiple frontend versions.

The two most active frontends are at the time of writing this one for terminals based on termbox-go and a GUI application based on Qt's QML scripting language.

There's also a Proof of Concept html frontend.

Editor

The Editor singleton represents the most fundamental interface that frontends use to access the backend. It keeps a list of editor windows, handles input, detects file changes as well as communicate back to the frontend as needed.

Window

At any time there can be multiple windows of the editor open. Each Window can have a different layout, settings and status.

View

The View class defines a "view" into a specific backing buffer. Multiple views can share the same backing buffer. For instance viewing the same buffer in split view, or viewing the buffer with one syntax definition in one view and another syntax definition in the other.

It is very closely related to the view defined in the Model-view-controller paradigm, and contains settings pertaining to exactly how a buffer is shown to the user.

Command

The command interface defines actions to be executed either for the whole application, a specific window or a specific view.

Key bindings

Key bindings define a sequence of key-presses, a Command and the command's arguments to be executed upon that sequence having been pressed.

Key bindings can optionally have multiple contexts associated with it which allows the exact same key sequence to have different meaning depending on context.

See http://godoc.org/github.com/limetext/lime/backend#QueryContextCallback for details.

Settings

Many of the components have their own key-value Settings object associated with it, but settings are also nested. In other words, if the settings key does not exist in the current object's settings, its parent's settings object is queried next which in turn will query its parent if its settings object didn't contain the key neither.

Functions

func NewPacket 

func NewPacket(path string) *packet

Initializes new packet with specific path

func PascalCaseToSnakeCase 

func PascalCaseToSnakeCase(in string) string

func ScanPackets 

func ScanPackets(path string) []*packet

Initialize scan for loading user and limetext defaults i.e settings, commands, snippets etc

Types

type ApplicationCommand 

type ApplicationCommand interface {
	Command
	// Execute this command
	Run() error
	// Returns whether this command is checked or not.
	// Used to display a checkbox in the user interface
	// for boolean commands.
	IsChecked() bool
}

The ApplicationCommand interface extends the base Command interface with functionality specific for ApplicationCommands.

type Args 

type Args map[string]interface{}

The Args type is just a generic string key and interface{} value map type used to serialize command arguments.

type BypassUndoCommand 

type BypassUndoCommand struct {
	DefaultCommand
}

The BypassUndoCommand is the same as the DefaultCommand type, except that its implementation of BypassUndo returns true rather than false.

func (*BypassUndoCommand) BypassUndo 

func (b *BypassUndoCommand) BypassUndo() bool

The BypassUndoCommand defaults to bypassing the undo stack.

type Command 

type Command interface {
	// Returns whether the Command is enabled or not.
	IsEnabled() bool

	// Returns whether the Command is visible in menus,
	// the goto anything panel or other user interface
	// that lists available commands.
	IsVisible() bool

	// Returns the textual description of the command.
	Description() string

	// Whether or not this Command bypasses the undo stack.
	BypassUndo() bool
}

The Command interface implements the basic interface that is shared between the different more specific command type interfaces.

In the traditional Model-view-controller design, Commands are roughly equivalent to the action-taking controller piece.

type CommandHandler 

type CommandHandler interface {
	Unregister(string) error
	Register(name string, cmd interface{}) error
	// TODO(q): Do the commands need to be split in separate lists?
	RunWindowCommand(*Window, string, Args) error
	RunTextCommand(*View, string, Args) error
	RunApplicationCommand(string, Args) error
}

type CustomInit 

type CustomInit interface {
	Init(args Args) error
}

The CustomInit interface can be optionally implemented by a Command and will be called instead of the default command initialization code.

type CustomSet 

type CustomSet interface {
	Set(v interface{}) error
}

The CustomSet interface can be optionally implemented by struct members of a concrete command struct.

If implemented, it'll be called by the default Command initialization code with the data gotten from the Args map.

type DefaultCommand 

type DefaultCommand struct{}

The DefaultCommand implements the default operation of the basic Command interface and is recommended to be used as the base when creating new Commands.

func (*DefaultCommand) BypassUndo 

func (d *DefaultCommand) BypassUndo() bool

The default is to not bypass the undo stack.

func (*DefaultCommand) Description 

func (d *DefaultCommand) Description() string

	// python files for setting is file content
	Get() interface{}

	// Reloads package data
	Reload()
}

type Plugin 

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

Plugin is a Package type containing some files with specific suffix that could be interpreted by lime text api(currently python) and some settings, snippets, commands and etc as packets

func NewPlugin 

func NewPlugin(path string, suffix string) *Plugin

Initializes a new plugin whith loading all of the settings, keymaps and etc. Suffix variable show's which file types we need for plugin for example if the plugin is written in python the suffix should be ".py". We will use this function at initialization to add user plugins and on new_plugin command

Scaning path for finding plugins that contain files whith specific suffix

func (*Plugin) Get 

func (p *Plugin) Get() interface{}

func (*Plugin) Reload 

func (p *Plugin) Reload()

On plugin reload we will scan for plugin files and packets in plugin path

type QueryContextCallback 

type QueryContextCallback func(v *View, key string, operator Op, operand interface{}, match_all bool) QueryContextReturn

The context is queried when trying to figure out what action should be performed when certain conditions are met.

Context is just a string identifier, an optional comparison operator, an optional operand, and an optional match_all boolean. The data of the context is optionally provided together with a key binding and the key's action will only be considered if the context conditions are met.

Exactly how these values are interpreted is up to the individual context handlers, which may be fully customized by implementing the callback in a plugin.

For instance pressing the key 'j' will have a different meaning when in a VI command mode emulation and when in a VI insert mode emulation. A plugin would then define two key binding entries for 'j', describe the key binding context to be able to discern which action is appropriate when 'j' is then pressed.

type QueryContextEvent 

type QueryContextEvent []QueryContextCallback

A QueryContextEvent is simply a bunch of QueryContextCallbacks.

func (*QueryContextEvent) Add 

func (qe *QueryContextEvent) Add(cb QueryContextCallback)

Add the provided QueryContextCallback to the QueryContextEvent. TODO(.): Support removing QueryContextCallbacks?

func (QueryContextEvent) Call 

func (qe QueryContextEvent) Call(v *View, key string, operator Op, operand interface{}, match_all bool) QueryContextReturn

Searches for a QueryContextCallback and returns the result of the first callback being able to deal with this context, or Unknown if no such callback was found.

type QueryContextReturn 

type QueryContextReturn int

The return value returned from a QueryContextCallback. 

const (
	True    QueryContextReturn = iota //< Returned when the context query matches.
	False                             //< Returned when the context query does not match.
	Unknown                           //< Returned when the QueryContextCallback does not know how to deal with the given context.
)

type TextCommand 

type TextCommand interface {
	Command
	// Execute this command with the specified View and Edit object
	// as the arguments
	Run(*View, *Edit) error
}

The TextCommand interface extends the base Command interface with functionality specific for TextCommands.

type UndoStack 

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

func (*UndoStack) Add 

func (us *UndoStack) Add(a *Edit)

Adds the provided Edit object to the UndoStack, potentially destroying the old redo stack if one had been created. TODO(.): It would be nice with branched undo histories

func (*UndoStack) GlueFrom 

func (us *UndoStack) GlueFrom(mark int)

Glues all edits from the position given by mark, to the current position in the UndoStack, replacing them by a single entry which will now be composite of all those other actions.

In other words, after the glue operation a single "undo" operation will then undo all of those edits and a single redo after that will redo them all again.

func (*UndoStack) Position 

func (us *UndoStack) Position() int

Returns the current position in the UndoStack.

func (*UndoStack) Redo 

func (us *UndoStack) Redo(hard bool)

Re-applies the next action in the undo stack if there are any actions on the stack that had been undone.

See comment in Undo regarding the use of "hard".

func (*UndoStack) Undo 

func (us *UndoStack) Undo(hard bool)

Reverts the last action on the UndoStack.

When the argument "hard" is set to true, the "last action" will be the last action that modified the contents of the buffer (rather than just changing the cursor position). In this case, all actions between the current action and the last "hard" action will be reverted.

type View 

type View struct {
	HasSettings
	HasId
	// contains filtered or unexported fields
}

A View provides a view into a specific underlying buffer with its own set of selections, settings, viewport, etc. Multiple Views can share the same underlying data buffer.

func (*View) AddRegions 

func (v *View) AddRegions(key string, regions []Region, scope, icon string, flags render.ViewRegionFlags)

AddRegions lets users mark text regions in a view with a scope name, gutter icon and ViewRegionflags which are then optionally used to alter the display of those regions.

Typical uses would be to draw squiggly lines under misspelled words, show an icon in the gutter to indicate a breakpoint, keeping track of snippet or auto-completion fields, highlight code compilation warnings, etc.

The regions will be automatically adjusted as appropriate when the underlying buffer is changed.

func (*View) BeginEdit 

func (v *View) BeginEdit() *Edit

Creates a new Edit object. Think of it a bit like starting an SQL transaction. Another Edit object should not be created before ending the previous one.

TODO(.): Is nesting edits ever valid? Perhaps a nil edit should be returned if the previous wasn't ended? What if it will never be ended? Leaving the buffer in a broken state where no more changes can be made to it is obviously not good and is the reason why ST3 removed the ability to manually create Edit objects to stop people from breaking the undo stack.

func (*View) Buffer 

func (v *View) Buffer() Buffer

Returns the underlying Buffer that this View is a view into.

func (*View) Classify 

func (v *View) Classify(point int) (res int)

func (v *View) Close()

Initiate the "close" operation of this view.

func (*View) CommandHistory 

func (v *View) CommandHistory(idx int, modifying_only bool) (name string, args Args, count int)

Returns the CommandHistory entry at the given relative index.

When "modifying_only" is set to true, only commands that actually changed the Buffer in some way (as opposed to just moving the cursor around) are counted as an index. That would be a "hard" command as it is referred to in UndoStack.Undo.

func (*View) EndEdit 

func (v *View) EndEdit(edit *Edit)

Ends the given Edit object.

func (*View) Erase 

func (v *View) Erase(edit *Edit, r Region)

func (*View) Insert 

func (v *View) Insert(edit *Edit, point int, value string) int

Inserts text at the given position in the provided edit object. Tabs are (sometimes, depending on the View's settings) translated to spaces. The return value is the length of the string that was inserted.

func (*View) IsDirty 

func (v *View) IsDirty() bool

Returns whether the underlying Buffer has any unsaved modifications. Note that Scratch buffers are never considered dirty.

func (*View) IsScratch 

func (v *View) IsScratch() bool

func (v *View) Save() error

Saves the file

func (*View) SaveAs 

func (v *View) SaveAs(name string) (err error)

Saves the file to the specified filename

func (*View) ScopeName 

func (v *View) ScopeName(point int) string

Returns the full concatenated nested scope name at point. See package lime/backend/parser for details.

func (*View) ScoreSelector 

func (v *View) ScoreSelector(point int, selector string) int

ScoreSelector() takes a point and a selector string and returns a score as to how good that specific selector matches the scope name at that point.

func (*View) Sel 

func (v *View) Sel() *RegionSet

Sel() returns a pointer to the RegionSet used by this View to mark possibly multiple cursor positions and selection regions.

Some quick notes: The actual cursor position is always in Region.B. Region{0,0} is a cursor at the start of the text (before any characters in the text).

Region{0,1} has the cursor at position 1 (after the first character), but also selects/highlights the first character. In this instance Region.A = 0, Region.B = 1, Region.Start() returns 0 and Region.End() returns 1.

Region{1,0} has the cursor at position 0 (before the first character), but also selects/highlights the first character. Think holding shift and pressing left on your keyboard. In this instance Region.A = 1, Region.B = 0, Region.Start() returns 0 and Region.End() returns 1.

func (*View) SetOverwriteStatus 

func (v *View) SetOverwriteStatus(s bool)

Checks the overwrite status property of the view. TODO(.): Couldn't this just be a value in the View's Settings?

func (*View) SetScratch 

func (v *View) SetScratch(s bool)

Sets the scratch property of the view. TODO(.): Couldn't this just be a value in the View's Settings?

func (*View) Transform
