Inherits the same alignment from the parent only valid for “alignSelf” property Since: Enumeration for the alignment of the flex items or lines when the items or lines do not use all the available space on the cross-axis. A number of token types common for all languages are defined in the TokenType interface. Enumeration for the alignment of the flex items when the items do not use all available space on the main-axis.

Inheritance diagram for Dali:: The flexible items are displayed vertically as a column, but in reverse order. Items are positioned at the beginning of the container. Below is an illustration of the various directions and terms as applied to a flex container with the “flex direction” defined as “row”. An important requirement for a syntax highlighting lexer is that its state must be represented by a single integer number returned from Lexer. If not, the returned handle is left uninitialized. GrammarKit plugin also has builtin JFlex support.

The same IElementType instance should be returned every time a particular token type is encountered by the lexer. At the center of the container. New Calling member functions with an uninitialized handle is not allowed. Reserve child property indices. The flexible items are displayed vertically as a column.

For example, a Java lexer could have separate states for top level context, comment context and string literal context. Token types for Properties language plugin.

The lexer used for syntax highlighting can be invoked incrementally to process only the changed part of a file, whereas lexers used in other contexts are always called to process an entire file, or a complete language construction embedded in a file in a different language. The flexible items are displayed horizontally as a row.

The API for the lexer is defined by the Devugide interface. It aims at providing a more efficient way to lay out, align and distribute space among items in the container, even when their size is unknown or dynamic. An important feature which can be implemented at lexer level is mixing languages within a file, for example, embedding fragments of Java code in some template fevguide.

It provides syntax highlighting and other useful features for editing JFlex files.

The lexer serves as a foundation for nearly all of the features of custom language plugins, from basic syntax highlighting to advanced code analysis features. This determines the direction that flex items are laid out in devgide flex container.

Changes this handle to point to another real object. Types of tokens for lexers are defined by instances of IElementType. From right to left. Enumeration for the wrap type of the flex container when there is no enough room for all the items on one flex line.

Implementing Lexer

At the end of the container. Flex items laid out in single line shrunk to fit the flex container along the main axis Since: A handle to the FlexContainer control Reimplemented from Dali:: The available values for alignSelf are: The lexer of the enclosing language needs to return the entire fragment of the embedded language as a single chameleon token, of lfex type defined by the embedded language.

From left to right. Enabling –charat option passes the source data for fex as a CharSequence and not as an array of characters. This is non-virtual since derived Handle types must not contain data or virtual methods. A reference to this. That state will be passed to the Lexer.

A lexer that can be used incrementally may need to return its statewhich means the context corresponding to each position in a file. Lexers, and in particular JFlex-based lexers, need to be created in such a way that they always match the entire contents of the file, without any gaps between tokens, and generate special tokens for characters which are not valid at their location.

Handle to a FlexContainer or an uninitialized handle Reimplemented from Dali:: The IDE invokes the lexer in three main contexts, and the plugin can provide different lexer implementations for these contexts:. Items are positioned with equal space between the lines. Downcasts an Object handle to FlexContainer. Creates the FlexContainer control.

If a language supports embedding its fragments in another language, it needs to define the chameleon token types for different types of fragments which can be embedded, and these token types need to implement the ILazyParseableElementType interface. FlexContainer felx a subset of the flexbox spec defined by W3C:.

The flexible items are displayed horizontally as a row, but in reverse order.

Devfuide has the ability to alter the width and height of its children i. The lexer, or lexical analyzerdefines how the contents of a file is broken into tokens. Custom language plugins should reuse these token types wherever applicable.
