# LuaJIT-ImGui
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
This is a LuaJIT binding for the excellent C++ immediate gui [imgui](https://github.com/ocornut/imgui).
|
||||
Uses cimgui to be the most "up to date" as possible.
|
||||
|
||||
There are backends for glfw, SDL2 and SDL3.
|
||||
|
||||
Notes:
|
||||
* currently this wrapper is based on version [1.92.8 docking of imgui]
|
||||
|
||||
# cloning
|
||||
|
||||
Remember to do a recursive cloning of the repo to pull submodules also.
|
||||
|
||||
git clone --recurse-submodules https://github.com/sonoro1234/LuaJIT-ImGui.git
|
||||
|
||||
If already cloned and updating do from this repo folder:
|
||||
|
||||
git submodule update --init --recursive
|
||||
|
||||
|
||||
# compiling
|
||||
|
||||
* linux cimgui_sdl (for love2d for example) needs: <code>sudo apt install libsdl2-dev</code>
|
||||
* run one of the scripts in the build directory from a sibling folder to the repo. If you want to install,
|
||||
(recomended) add this <code>-DLUAJIT_BIN="folder where LuaJIT is"</code> to the cmake command.
|
||||
* make (or make install).
|
||||
* If you didnt install in LuaJIT directory, set basedir variable in imgui.lua to the directory libimgui is found.
|
||||
* Alternatively you can build https://github.com/sonoro1234/anima which includes LuaJIT-ImGui and dependencies.
|
||||
|
||||
# trying
|
||||
|
||||
* Remember you also need GLFW https://github.com/sonoro1234/LuaJIT-GLFW or SDL2 https://github.com/sonoro1234/LuaJIT-SDL2 .
|
||||
* You have some scripts on the examples folder.
|
||||
* New module imgui.window for simplified use. (see window_drag_drop.lua)
|
||||
* In case you are in a hurry, you can get all done in the releases (GLFW version only).
|
||||
* Releases are now done in https://github.com/sonoro1234/anima
|
||||
|
||||
# binding generation
|
||||
|
||||
* if cimgui is updated the binding can be remade with ./lua/build.bat
|
||||
|
||||
# used in
|
||||
|
||||
* https://github.com/sonoro1234/anima
|
||||
* can be used for LOVE2D as explained in https://github.com/sonoro1234/LuaJIT-ImGui/issues/47

# Contributor Covenant Code of Conduct
|
||||
|
||||
## Our Pledge
|
||||
|
||||
We as members, contributors, and leaders pledge to make participation in our
|
||||
community a harassment-free experience for everyone, regardless of age, body
|
||||
size, visible or invisible disability, ethnicity, sex characteristics, gender
|
||||
identity and expression, level of experience, education, socio-economic status,
|
||||
nationality, personal appearance, race, caste, color, religion, or sexual
|
||||
identity and orientation.
|
||||
|
||||
We pledge to act and interact in ways that contribute to an open, welcoming,
|
||||
diverse, inclusive, and healthy community.
|
||||
|
||||
## Our Standards
|
||||
|
||||
Examples of behavior that contributes to a positive environment for our
|
||||
community include:
|
||||
|
||||
* Demonstrating empathy and kindness toward other people
|
||||
* Being respectful of differing opinions, viewpoints, and experiences
|
||||
* Giving and gracefully accepting constructive feedback
|
||||
* Accepting responsibility and apologizing to those affected by our mistakes,
|
||||
and learning from the experience
|
||||
* Focusing on what is best not just for us as individuals, but for the overall
|
||||
community
|
||||
|
||||
Examples of unacceptable behavior include:
|
||||
|
||||
* The use of sexualized language or imagery, and sexual attention or advances of
|
||||
any kind
|
||||
* Trolling, insulting or derogatory comments, and personal or political attacks
|
||||
* Public or private harassment
|
||||
* Publishing others' private information, such as a physical or email address,
|
||||
without their explicit permission
|
||||
* Other conduct which could reasonably be considered inappropriate in a
|
||||
professional setting
|
||||
|
||||
## Enforcement Responsibilities
|
||||
|
||||
Community leaders are responsible for clarifying and enforcing our standards of
|
||||
acceptable behavior and will take appropriate and fair corrective action in
|
||||
response to any behavior that they deem inappropriate, threatening, offensive,
|
||||
or harmful.
|
||||
|
||||
Community leaders have the right and responsibility to remove, edit, or reject
|
||||
comments, commits, code, wiki edits, issues, and other contributions that are
|
||||
not aligned to this Code of Conduct, and will communicate reasons for moderation
|
||||
decisions when appropriate.
|
||||
|
||||
## Scope
|
||||
|
||||
This Code of Conduct applies within all community spaces, and also applies when
|
||||
an individual is officially representing the community in public spaces.
|
||||
Examples of representing our community include using an official e-mail address,
|
||||
posting via an official social media account, or acting as an appointed
|
||||
representative at an online or offline event.
|
||||
|
||||
## Enforcement
|
||||
|
||||
Instances of abusive, harassing, or otherwise unacceptable behavior may be
|
||||
reported to the community leaders responsible for enforcement at
|
||||
[INSERT CONTACT METHOD].
|
||||
All complaints will be reviewed and investigated promptly and fairly.
|
||||
|
||||
All community leaders are obligated to respect the privacy and security of the
|
||||
reporter of any incident.
|
||||
|
||||
## Enforcement Guidelines
|
||||
|
||||
Community leaders will follow these Community Impact Guidelines in determining
|
||||
the consequences for any action they deem in violation of this Code of Conduct:
|
||||
|
||||
### 1. Correction
|
||||
|
||||
**Community Impact**: Use of inappropriate language or other behavior deemed
|
||||
unprofessional or unwelcome in the community.
|
||||
|
||||
**Consequence**: A private, written warning from community leaders, providing
|
||||
clarity around the nature of the violation and an explanation of why the
|
||||
behavior was inappropriate. A public apology may be requested.
|
||||
|
||||
### 2. Warning
|
||||
|
||||
**Community Impact**: A violation through a single incident or series of
|
||||
actions.
|
||||
|
||||
**Consequence**: A warning with consequences for continued behavior. No
|
||||
interaction with the people involved, including unsolicited interaction with
|
||||
those enforcing the Code of Conduct, for a specified period of time. This
|
||||
includes avoiding interactions in community spaces as well as external channels
|
||||
like social media. Violating these terms may lead to a temporary or permanent
|
||||
ban.
|
||||
|
||||
### 3. Temporary Ban
|
||||
|
||||
**Community Impact**: A serious violation of community standards, including
|
||||
sustained inappropriate behavior.
|
||||
|
||||
**Consequence**: A temporary ban from any sort of interaction or public
|
||||
communication with the community for a specified period of time. No public or
|
||||
private interaction with the people involved, including unsolicited interaction
|
||||
with those enforcing the Code of Conduct, is allowed during this period.
|
||||
Violating these terms may lead to a permanent ban.
|
||||
|
||||
### 4. Permanent Ban
|
||||
|
||||
**Community Impact**: Demonstrating a pattern of violation of community
|
||||
standards, including sustained inappropriate behavior, harassment of an
|
||||
individual, or aggression toward or disparagement of classes of individuals.
|
||||
|
||||
**Consequence**: A permanent ban from any sort of public interaction within the
|
||||
community.

# Colorizing Text Editor and Text Diff for Dear ImGui
|
||||
|
||||
</div>
|
||||
|
||||
> [!NOTE]
|
||||
> The editor is being refactored to enable new features like Word Wrap, Line Folding, full MiniMaps, Autocomplete and
|
||||
> Language Server connectivity. This refactoring will break backwards compatibility. A preview is avalable in
|

|
||||
> architecture will become the master branch.
|
||||
|
||||
TextEdit is a syntax highlighting text editor for
|
||||
[Dear ImGui](https://github.com/ocornut/imgui) and it was originally developed by
|
||||
[Balázs Jákó](https://github.com/BalazsJako/ImGuiColorTextEdit). Unfortunately, he no
|
||||
longer has time to work on the project. In fact, the last update to his repository was
|
||||
in June 2019. As a result, over 200 forks exist by people who like his work but want
|
||||
to fix bugs and/or add new features. A fork by
|
||||
[Santiago](https://github.com/santaclose/ImGuiColorTextEdit), also known as santaclose,
|
||||
was the most actively maintained version (over 220 commits ahead of the original version)
|
||||
when I was looking for a syntax highlighting text editor for Dear ImGui in late 2023.
|
||||
This repository was originally a fork of Santiago's version and I tried to enhance it.
|
||||
|
||||
In late December 2024, I decided that it was better for me to rewrite the code from
|
||||
the ground up while preserving the majority of the public APIs so it would be relatively
|
||||
simple for me (and others) to reuse my rewrite. One of my fundamental arguments
|
||||
for the rewrite was that the code had become hard to read and maintain (at least for me).
|
||||
I decided to create a more object-oriented internal architecture (see below) that made
|
||||
it clear who was responsible for what by using a layered approach. While rewriting
|
||||
the code, a number of new features were also added.
|
||||
|
||||
The rewrite and now the maintenance of this code is part of a larger project
|
||||
([ObjectTalk](https://github.com/goossens/ObjectTalk)) and this repository is simply
|
||||
a snapshot of the relevant editor code to provide reuse. As part of this code is
|
||||
automatically generated, references to the master project are provided where required.
|
||||
You can find all text editor source code components here in the
|
||||
[ObjectTalk repository](https://github.com/goossens/ObjectTalk/tree/master/3rdparty/imguieditor).
|
||||
|
||||
To respect its origins, this repository will remain a fork (of a fork) although
|
||||
there is now little code in common.
|
||||
|
||||
|
||||
|
||||
Note: In the screenshot above, the tabs and the menubar are not part of the
|
||||
text editor widget. They are part of a custom enclosing IDE (which is part of
|
||||
the larger [ObjectTalk](https://github.com/goossens/ObjectTalk) project).
|
||||
By not putting those things in the editor, integrators have maximum
|
||||
flexibility to wrap the editor in their own context in the way they see fit. The
|
||||
public API to externally implement these features is however included.
|
||||
|
||||
## Features
|
||||
|
||||
- Works on MacOS, Linux and Windows.
|
||||
- Has look and feel similar to Visual Studio Code.
|
||||
- Works with latest Dear ImGui version (currently v1.92.7) and does not use deprecated functions.
|
||||
- Supports dynamic font sizes (courtesy of Dear ImGui v1.92+). Implemented in example application.
|
||||
- Supports UTF-8 encoding with 16/32 bit codepoints (based on Dear ImGui configuration, see below).
|
||||
- Is C++17 based (not unreasonable in 2026 I think) although Dear ImGui still uses C++11.
|
||||
- Has no runtime dependencies other than Dear ImGui and the C++17 Standard Template Library (STL).
|
||||
- Has full undo/redo capabilities and supports native clipboard with UTF-8 encoded strings.
|
||||
- Has extendable syntax highlighting for multiple languages and API for custom languages.
|
||||
- Has customizable color palettes (a dark and light version that work with Dear ImGui defaults are included).
|
||||
- Has option to automatically insert spaces on tabs.
|
||||
- Has find/replace user interface and API with full undo/redo.
|
||||
- Find has options for whole word and/or case-sensitive searches.
|
||||
- Provides optional autocomplete framework (see [more information here](docs/autocomplete.md)).
|
||||
- Has marker API to specify lines and/or line numbers to highlight and optional show tooltips (
|
||||
see [example](docs/markers.md)).
|
||||
- Has optional scrollbar minimap to render cursor, selection and marker locations.
|
||||
- Provides middle-mouse pan and scroll functions like CAD programs and browsers.
|
||||
- Has API to attach user data to select lines or all lines (see [example](docs/userData.md)).
|
||||
- Has API to decorate each line (useful for debuggers and IDEs) (see [example](docs/lineDecorator.md)).
|
||||
- Provides optional and customizable right click (control + click on MacOS) context menus for line numbers or text
|
||||
lines (see [example](docs/contextMenus.md))
|
||||
- Provides auto completion for paired glyphs (\[, \{, \(, \", \') (can be turned on and off).
|
||||
- If auto complete is turned on, accidentally typed closing glyphs are ignored.
|
||||
- If auto complete is turned on, selections can be surrounded by paired glyphs.
|
||||
- Supports blinking cursor (can be turned on/off using Dear ImGui's global io.ConfigInputTextCursorBlink flag).
|
||||
- Supports bracket matching and coloring similar to Visual Studio Code (can be turned on and off).
|
||||
- Supports multiple cursors and multiple selections.
|
||||
- Provides auto indent with simplified implementation (can be turned on and off).
|
||||
- Has API to filter selections (with full undo support).
|
||||
- Uppercase/lowercase filter is example of selection filtering.
|
||||
- Has API to filter each line in editor (with full undo support).
|
||||
- Tabs to Space (and visa versa) are examples of line filtering.
|
||||
- Has API to strip trailing whitespaces.
|
||||
- Provides whitespace indicators for tabs and spaces (can be turned on and off individually or collectively).
|
||||
- No longer uses regular expressions for colorizing text (see below).
|
||||
- Provides an optional companion widget to show source code differences between versions (see below).
|
||||
|
||||
## Integration
|
||||
|
||||
As explained above, the editor is developed and maintained as part of a larger project.
|
||||
In that bigger project, the editor is spread out over multiple source files and some
|
||||
of those are automatically generated using tools or derived from datasets (like the
|
||||
unicode database). Every time the editor is updated in the bigger project, relevant
|
||||
files are concatenated into a simple 2 (or 5 if you also want to use TextDiff)
|
||||
file distribution which is included here.
|
||||
|
||||
This repository therefore provides a simple mechanism to reuse the editor in any
|
||||
Dear ImGui context by doing the following:
|
||||
|
||||
- Include the TextEditor.cpp and TextEditor.h files in your project.
|
||||
- Instantiate a TextEditor object for each editor widget you need.
|
||||
- Use the public API to set editor options or interact with the editor's contents.
|
||||
- Call the TextEditor's Render member function every frame in your Dear ImGui loop.
|
||||
- If you plan to use non-ASCII characters in your text, see the Unicode section below.
|
||||
- Configure Dear ImGui's clipboard functions since that is what this editor uses.
|
||||
|
||||
If you also want to use the TextDiff widget, you must:
|
||||
|
||||
- Include TextDiff.cpp, TextDiff.h and dtl.h in your project.
|
||||
- Instantiate a TextDiff object for each diff widget you need.
|
||||
- Use the public API to set diff options.
|
||||
- Call the TextDiff's Render member function every frame in your Dear ImGui loop.
|
||||
- If you properly configured Dear ImGui for the TextEditor (see above), you are good to go.
|
||||
|
||||
For a complete example, please see the [example folder](example/).
|
||||
|
||||
**Note**: Like ImGui, it is recommended that you compile and link TextEditor and TextDiff
|
||||
as a static library or directly as part of your sources (as suggested above).
|
||||
However, if you must and are compiling TextEditor and/or TextDiff as separate DLLs, make sure
|
||||
you set the current ImGui context with TextEditor::SetImGuiContext(ImGuiContext* ctx).
|
||||
This ensures that global ImGui variables are correctly shared across the DLL boundary.
|
||||
See GImGui documentation in imgui.cpp for more details.
|
||||
|
||||
## Default Keyboard and Mouse Mappings
|
||||
|
||||
- In the mappings listed below, the following modifier keys are used:
|
||||
- Ctrl: this refers to the Command key on MacOS and the Control key on Linux and Windows.
|
||||
- Alt: this refers to the Option key on MacOS and the Alt key on Linux and Windows.
|
||||
- Shift: as you would expect on all platforms.
|
||||
- If a keyboard has a left and right version of these modifiers, the meaning is not different.
|
||||
|
||||
- Cursor Movements:
|
||||
- Single left mouse click moves the cursor.
|
||||
- Arrow keys move cursor left, right, up and down.
|
||||
- PageUp and PageDown do what you expect.
|
||||
- Ctrl-UpArrow and Ctrl-DownArrow move to the start/end of the document.
|
||||
- Home and End keys move to the start/end of the line.
|
||||
- Holding down the Shift key extends the current selection(s).
|
||||
- Holding down the Alt key with the left or right arrow moves a whole word on MacOS.
|
||||
- Holding down the Ctrl key with the left or right arrow moves a whole word on Linux and Windows.
|
||||
|
||||
- Panning and Scrolling:
|
||||
- The text scrolls automatically when you move the cursor through keyboard actions.
|
||||
- Mouse actions that extend the selections also apply auto scrolling.
|
||||
- The text in the editor can still be scrolled using those little bars that were invented in the 1970's.
|
||||
- Devices with scroll wheels or those that simulated vertical and horizontal scroll wheels (like a touch pad, a
|
||||
mouse with a builtin touch pad or a pen) can also scroll the text. This is actually implemented in Dear ImGui (and
|
||||
used by the editor) and must be supported by your backend.
|
||||
- The middle mouse button on a three-button mouse (or whatever is reported by your OS as a middle mouse button
|
||||
event) enters pan or scroll mode mode depending on the configuration. Pan mode is the default and you can switch
|
||||
this to Scroll mode by calling SetMiddleMouseScrollMode(). Calling SetMiddleMousePanMode() switches it back. The
|
||||
example application uses a menu option to toggle modes.
|
||||
- In pan mode, the text is grabbed and dragged as the cursor moves and as long as the middle mouse button is down.
|
||||
- When you mouse approaches the edges of the editor window, it enters continuous panning mode and the further you
|
||||
move away form the window, the faster it pans.
|
||||
- Panning as described above is typical in CAD or 3D type applications.
|
||||
- In scroll mode, you can release the middle mouse button and scroll the text just like you can in some browsers.
|
||||
- Scroll mode is ended by any clicking any mouse button.
|
||||
- Panning and scrolling operate in opposite directions as they are different paradigms.
|
||||
- An optional indicator (default is on) is shown in the center of the editor window when entering pan/scroll mode.
|
||||
If anybody finds this annoying, it can be turned off through an API by calling SetShowPanScrollIndicatorEnabled(
|
||||
false).
|
||||
|
||||
- Cursors and Selections:
|
||||
- Alt with single left mouse click creates a new cursor on MacOS.
|
||||
- Ctrl with single left mouse click creates a new cursor on Linux and Windows.
|
||||
- Ctrl-A select all text.
|
||||
- Ctrl-D creates a new cursor and selects the next instance of the current selection.
|
||||
- Double left mouse clicks on a curly bracket select the content of the relevant block and replaces all previous
|
||||
cursors.
|
||||
- Shift + Double left mouse clicks on a curly bracket select the content of the relevant block including the
|
||||
brackets and replaces all previous cursors.
|
||||
- Double left mouse clicks not on a bracket or parenthesis, select a word. Adding Shift extends current selection.
|
||||
- Triple left mouse clicks select a line. Adding Shift extends current selection.
|
||||
- Dragging mouse with left mouse button selects text. Shift extends current selection.
|
||||
- Alt-Shift-RightArrow (on MacOS) and Ctrl-Shift-RightArrow (on Linux and Windows) grows all selections to outer
|
||||
blocks. First just the content of the block, than including the curly brackets. Continuously hitting the key
|
||||
combination keeps growing the selections.
|
||||
- Alt-Shift-LeftArrow (on MacOS) and Ctrl-Shift-LeftArrow (on Linux and Windows) shrinks all selections to inner
|
||||
blocks. First including the curly brackets, that just the content of the block. Continuously hitting the key
|
||||
combination keeps shrinking the selections.
|
||||
- Left mouse clicking or dragging over line numbers select line(s).
|
||||
- When multiple cursors are active, hitting the ESC key cancels them.
|
||||
|
||||
- Clipboard Operations:
|
||||
- Ctrl-X or Shift-Delete cuts selected text or current line if no selection.
|
||||
- Ctrl-C or Ctrl-Insert copies selected text or current line if no selection.
|
||||
- Ctrl-V or Shift-Insert pastes clipboard content.
|
||||
- Ctrl-Z undos the last action.
|
||||
- Shift-Ctrl-Z or Ctrl-Y redos the last undone action.
|
||||
|
||||
- Insert Text:
|
||||
- Ctrl-Enter adds line below.
|
||||
- Ctrl-Shift-Enter adds line above.
|
||||
|
||||
- Delete Text:
|
||||
- Backspace deletes character to the left of cursor or deletes selection(s).
|
||||
- Delete deletes character to the right of cursor or deletes selection(s).
|
||||
- Ctrl-Shift-K deletes all selected lines.
|
||||
|
||||
- Text Manipulation:
|
||||
- Ctrl-] indents current line or current lines.
|
||||
- Ctrl-[ de-indents current line or current lines.
|
||||
- Tab with selection indents current line or current lines.
|
||||
- Ctrl-UpArrow moves current or all selected lines up.
|
||||
- Ctrl-DownArrow moves current or all selected lines down.
|
||||
- Ctrl-/ toggles comments if language with single line comments is specified.
|
||||
|
||||
- Find & Replace:
|
||||
- Ctrl-f opens the find and replace window.
|
||||
- If text is selected when Ctrl-f is hit, the selected text is used as the search term if the start and end are on
|
||||
the same line.
|
||||
- Else if the cursor is over a word when Ctrl-f is hit, that word is used as the search term.
|
||||
- In all other cases, the previous search term is used.
|
||||
- When the search and replace window is visible, hitting the ESC button closes it.
|
||||
- Shift-Ctrl-f finds all instances and makes them separate cursors.
|
||||
- Ctrl-g finds n
|
||||
|
||||
- Autocomplete:
|
||||
- Once configured, Ctrl-space (or a custom key combination) triggers a manual autocomplete (even on MacOS as
|
||||
Cmd-space globally triggers Spotlight searching on that platform).
|
||||
- Typing also triggers autocomplete (based on context).
|
||||
- You can configure which triggers you want (the default is for both manual and automatic (by just typing) to be
|
||||
active)
|
||||
- Autocomplete does not work when multiple cursors are active.
|
||||
|
||||
- Other:
|
||||
- Insert key toggles between insert (default) and overwrite modes.
|
||||
|
||||
## Unicode and UTF-8
|
||||
|
||||
This rewrite of TextEditor uses UTF-8 encoded strings for the public API
|
||||
and to interact with the clipboard like the original TextEditor versions.
|
||||
The original and most of its forks use UTF-8 on the private side as well
|
||||
which is effective from a storage perspective but it makes all the
|
||||
processing a lot harder as you constantly have to parse UTF-8 sequences.
|
||||
|
||||
This rewrite internally uses unicode codepoints that are either 16 or 32 bits
|
||||
depending on how Dear ImGui is configured. If IMGUI_USE_WCHAR32 is defined,
|
||||
Dear ImGui as well as this editor use 32 bits to store a codepoint. If it is not
|
||||
defined (which is the default), 16 bits are used for each codepoint which
|
||||
basically limits unicode support to the Basic Multilingual Plane (see
|
||||
[this article on Wikipedia](https://en.wikipedia.org/wiki/Plane_(Unicode))).
|
||||
|
||||
Regardless of whether 16 or 32 bit codepoints are used, it is your responsibility
|
||||
to ensure Dear ImGui is configured with the correct font and font size. As of
|
||||
Dear ImGui v1.92, you can now use dynamically sized fonts and use any font glyph
|
||||
without setting up glyph ranges or a font atlas. All this functionality is in the
|
||||
Dear ImGui core and the TextEditor uses it. Please see the example application on
|
||||
how to use PushFont/PopFont around the TextEditor Render function. The demo app
|
||||
also shows how to increase/decrease the font size on the fly.
|
||||
|
||||
## Architecture
|
||||
|
||||
While this editor relies on [Omar Cornut's Dear ImGui](https://github.com/ocornut/imgui),
|
||||
it does not follow the "pure" one widget - one function approach. Since the editor
|
||||
has to maintain a relatively complex and large internal state, it did not seem
|
||||
to be practical to try and enforce full immediate mode. It therefore stores
|
||||
its internal state in an object instance which is reused across frames. This
|
||||
object is an instance of the TextEditor class which not only stores the
|
||||
internal state, it also provides the public API. The "Render" member functions
|
||||
however works like a normal Dear ImGui widget. It creates a child window to
|
||||
render the editor so you can call Dear ImGui window functions like SetNextWindowSize
|
||||
or set the font before calling Render.
|
||||
|
||||
The block diagram below shows the architecture of this widget. At the top is
|
||||
the public facing TextEditor instance and at the bottom are the private classes
|
||||
that store and maintain the internal state.
|
||||
|
||||
|
||||
|
||||
#### Document
|
||||
|
||||
This class, as the name suggests, stores the document that's being edited.
|
||||
Internally, a Document is a std::vector of Lines that themselves are
|
||||
std::vectors of Glyphs.
|
||||
|
||||
The Document class translates from the external UTF-8 encoding to the internal
|
||||
codepoints and provides a number of member functions to manipulate contents,
|
||||
calculate coordinates, assist searches and track overall content state.
|
||||
|
||||
The Line and Glyph classes are used to represent the document's structure with
|
||||
Glyph just holding a codepoint and a color.
|
||||
|
||||
#### Cursors
|
||||
|
||||
The Cursors class maintains a list of Cursor instances and operates very much
|
||||
like cursors do in Visual Studio Code. The list of cursors consists of the
|
||||
main cursor (which is always present) and a optional set of additional cursors.
|
||||
The last cursor added is considered the current cursor which has meaning for
|
||||
some actions or API calls.
|
||||
|
||||
#### Transactions
|
||||
|
||||
This class contains a list of Transaction records to support do/undo/redo
|
||||
operations. Each Transaction record contains insert and delete operations
|
||||
performed on a document.
|
||||
|
||||
#### Colorizer
|
||||
|
||||
The colorizer maintains the color state of each glyph based on the rules
|
||||
provided by the specifications in the Language object. The original version
|
||||
used regular expressions for some languages but this was/is not very
|
||||
performant. The new colorizer is based on multiple state-transition engines
|
||||
that make it easier to express language rules and also improves performance.
|
||||
The new colorizer only effects lines that have changed but keep in mind, that
|
||||
for instance opening a multiline comment at the start of the document,
|
||||
causes the entire document to be re-colored. Luckily the new engine is fast
|
||||
enough that you don't notice this and it would only affect a single frame. I
|
||||
think it is also important to point out that this widget is not really intended
|
||||
for mega/gigabyte size text files. For those, I would still use a regular text
|
||||
editors (if you can find one that can handle that requirement).
|
||||
|
||||
#### Bracketeer
|
||||
|
||||
This class keeps track of where bracket pairs (parenthesis, square brackets and
|
||||
curly brackets) are in the document so they can be highlighted and colorized
|
||||
when this feature is activated. It will also colorize unbalanced brackets as
|
||||
errors. Brackets in comments and strings are ignored.
|
||||
|
||||
#### Autocomplete
|
||||
|
||||
This class keeps track of autocomplete activities when the feature is configured.
|
||||
Once autocomplete is triggered, this class tracks the state, interacts with the
|
||||
user and uses an external callback to provide suggestions in the current context
|
||||
(see [details here](docs/autocomplete.md)).
|
||||
|
||||
#### Coordinate
|
||||
|
||||
Coordinates represent a character coordinate from the user's point of view,
|
||||
i. e. consider an uniform grid on the screen as it is rendered, and each cell
|
||||
has its own coordinate, starting from Tabs are counted as [1..tabsize]
|
||||
spaces, depending on how many spaces are necessary to reach the next tab stop.
|
||||
For example, coordinate (1, 5) represents the character 'B' in a line "\tABC",
|
||||
when tabsize = 4, because it is rendered as " ABC" on the screen.
|
||||
|
||||
#### TextEditor
|
||||
|
||||
As mentioned above, the TextEditor class provides the public API. As is true
|
||||
for all Dear InGui and the original text editor, all public member functions start
|
||||
with an uppercase letter. Internally, all private member functions and variables
|
||||
start with a lowercase letter so it's easy to see what's public and what's private.
|
||||
|
||||
In addition to being the public interface, the TextEditor class is also responsible
|
||||
for synchronizing the state of the lower levels of the architecture. When for
|
||||
instance the user pastes some text, TextEditor ensures that the Document gets
|
||||
updated, Cursors get adjusted (if required), Transaction records are created (so
|
||||
this paste operation can be undone and redone) and the Colorizer/Bracketeer are
|
||||
informed of the changes.
|
||||
|
||||
The final responsibility of the TextEditor class is overall rendering and
|
||||
user input (keyboard and mouse) processing.
|
||||
|
||||
#### TextDiff
|
||||
|
||||
TextDiff is a separate widget that is derived from TextEditor which allows
|
||||
you to show the differences between two versions of some code while preserving color
|
||||
highlighting. The code for this widget is in separate files (see integration above)
|
||||
so it is optional. TextDiff is readonly and has two modes:
|
||||
|
||||
- **Integrated view** where differences are depicted vertically using the standard "diff" look and feel. This view is
|
||||
implemented as a read-only TextEditor with markings and a line decorator which means that functions like text select
|
||||
and copy are available. This is the default view.
|
||||
|
||||
- **Side-by-side view** where the original and altered versions are shown/compared side-by-side. This a a custom static
|
||||
view that does not have the usual TextEditor features like text select or copy. Scrolling however is available.
|
||||
|
||||
In both modes, the provided text can be colored based on a specified language and
|
||||
color palette like in the TextEditor. The background colors for the difference
|
||||
highlighting are not part of the palette but can still be changed through a the public API.
|
||||
|
||||
Below are two screenshots of its use in both modes. Have a look at the code in the [example application](example/) to
|
||||
see how easy it is to use this TextDiff widget.
|
||||
|
||||

||||

||||
## Issues
|
||||
|
||||
If you are interested in using this Text Editor, steal parts of the code, make
|
||||
suggestions for improvements or contribute fixes/enhancements, be my guest as this
|
||||
repository is released under the MIT license. For people that want to contribute,
|
||||
[Contributing Guidelines](CONTRIBUTING.md) and a [Code of Conduct](CODE_OF_CONDUCT.md)
|
||||
are available. If you find any problems or want to make a suggestion for improvement, please
|
||||
[raise an issue on this repository](https://github.com/goossens/ImGuiColorTextEdit/issues).

|
||||
## Credits
|
||||
|
||||
This version of ImGuiColorTextEdit was written from scratch by [Johan A. Goossens](https://github.com/goossens)
|
||||
and if you end up using (parts of) this repository a shoutout or Github star would be appreciated.
|
||||
|
||||
Thank you to [Omar Cornut](https://github.com/ocornut/imgui) for creating Dear ImGui
|
||||
in the first place. Without you, this editor would not exist.
|
||||
|
||||
I owe a great deal of gratitude to [Balázs Jákó](https://github.com/BalazsJako/ImGuiColorTextEdit)
|
||||
who started this editor many years ago.
|
||||
|
||||
I also have to thank [Santiago (santaclose)](https://github.com/santaclose/ImGuiColorTextEdit)
|
||||
for reviving this project, merging the unfinished developments and pull requests.
|
||||
He was also responsible for adding features to the editor like multiple cursors.
|
||||
|
||||
Given that neither Balázs nor Santiago kept a credits list, it is highly likely
|
||||
that many others have also made contributions. Theoretically I could go through
|
||||
all the issues on the original and the fork but I think I have better use for my
|
||||
time. If you believe you deserve credit here, please raise an issue with reference
|
||||
to your work. I'll gladly add it.

# Autocomplete
|
||||
|
||||
The text editor provides an optional autocomplete framework. Once configured, the editor
|
||||
takes care of activation events (triggering), state tracking, visualization and insertion
|
||||
of suggestions with full undo/redo. The application is responsible for providing the list
|
||||
of suggestions through a callback or the API. This allows simple implementations to provide
|
||||
suggestions in realtime and allows other implementations to do things asynchronously like
|
||||
reaching out to a language server. Autocomplete can't be triggered when multiple cursors
|
||||
are active as this causes a mess. Try it in Visual Studio Code if you want to see what I mean.
|
||||
|
||||
|
||||
|
||||
To activate the feature, the app must provide a configuration like:
|
||||
|
||||
```c++
|
||||
TextEditor::AutoCompleteConfig config;
|
||||
|
||||
config.callback = [this](TextEditor::AutoCompleteState& state) {
|
||||
....
|
||||
};
|
||||
|
||||
editor.SetAutoCompleteConfig(&config);
|
||||
```
|
||||
|
||||
Deactivation can be achieved by passing **nullptr** to **SetAutoCompleteConfig**.
|
||||
The **TextEditor::AutoCompleteConfig** class contains all the configuration options
|
||||
and is defined as (please note defaults):
|
||||
|
||||
```c++
|
||||
class AutoCompleteConfig {
|
||||
public:
|
||||
// specifies whether typing by the user triggers autocomplete
|
||||
bool triggerOnTyping = true;
|
||||
|
||||
// specifies whether the specified shortcut triggers autocomplete
|
||||
bool triggerOnShortcut = true;
|
||||
|
||||
// specifies whether typing (or shortcut) in comments or strings triggers autocomplete
|
||||
bool triggerInComments = false;
|
||||
bool triggerInStrings = false;
|
||||
|
||||
// manual trigger key sequence (default is Ctrl+space on all platforms, even MacOS)
|
||||
// remember Dear ImGui reverses Ctrl and Command on MacOS
|
||||
#if __APPLE__
|
||||
ImGuiKeyChord triggerShortcut = ImGuiMod_Super | ImGuiKey_Space;
|
||||
#else
|
||||
ImGuiKeyChord triggerShortcut = ImGuiMod_Ctrl | ImGuiKey_Space;
|
||||
#endif
|
||||
|
||||
// see if single suggestions are automatically inserted
|
||||
// this only works when triggered manually
|
||||
bool autoInsertSingleSuggestions = false;
|
||||
|
||||
// delay in milliseconds between autocomplete trigger and suggestions popup
|
||||
std::chrono::milliseconds triggerDelay{200};
|
||||
|
||||
// text label used when no suggestions are available (this allows for internationalization)
|
||||
std::string noSuggestionsLabel = "No suggestions";
|
||||
|
||||
// called when autocomplete is configured, active and the editor needs an updated suggestions list
|
||||
// callback must populate and order suggestions in state object
|
||||
// suggestion list is not cleared by editor between callbacks
|
||||
// callback is called during the rendering process (so don't take too long)
|
||||
|
||||
// if it takes too long, applications should do search in separate thread and
|
||||
// use API to report results (see SetAutoCompleteSuggestions)
|
||||
// callback should set suggestionsPromise to true in this case
|
||||
std::function<void(AutoCompleteState&)> callback;
|
||||
|
||||
// optional opaque void* that must be managed externally but passed to callback
|
||||
void* userData = nullptr;
|
||||
};
|
||||
```
|
||||
|
||||
When the callback is activated, a **TextEditor::AutoCompleteState** object is passed
|
||||
informing the app about the context and providing space to return suggestions.
|
||||
It is defined as:
|
||||
|
||||
```c++
|
||||
class AutoCompleteState {
|
||||
public:
|
||||
// current context (strings = UTF-8, columns = Nth visible column and indices = Nth codepoint)
|
||||
// to understand the difference between column and index, think like a tab :-)
|
||||
std::string searchTerm;
|
||||
size_t line;
|
||||
size_t searchTermStartColumn;
|
||||
size_t searchTermStartIndex;
|
||||
size_t searchTermEndColumn;
|
||||
size_t searchTermEndIndex;
|
||||
|
||||
bool inIdentifier;
|
||||
bool inNumber;
|
||||
bool inComment;
|
||||
bool inString;
|
||||
|
||||
// currently selected language (could be nullptr if no language is selected)
|
||||
const Language* language;
|
||||
|
||||
// opaque void* provided by app when autocomplete was setup
|
||||
void* userData;
|
||||
|
||||
// auto complete suggestions te be provided by app callback (the app is responsible for sorting)
|
||||
|
||||
// the editor does not automatically include language specific keywords or identifiers in the suggestion list
|
||||
// this is left to the application so it can be context specific in case a language server is used
|
||||
// a pointer to the current language definition is provided so callbacks have easy access
|
||||
std::vector<std::string> suggestions;
|
||||
|
||||
// set this to true if you are building the suggestion list asynchronously and provide it later
|
||||
// this way autocomplete is not cancelled if the suggestion list is empty and the user hits tab or enter
|
||||
bool suggestionsPromise = false;
|
||||
};
|
||||
```
|
||||
|
||||
The editor also comes with a Trie class that implements fuzzy searching and
|
||||
the example app shows how it can be used. Given that this is a primitive,
|
||||
poor-man's solution, more sophisticated solutions probably required external
|
||||
language engines/services that are beyond the scope of this editor. With the
|
||||
provided API however, connections to external capabilities can be established
|
||||
and context-sensitive suggestions can be provided based on the most advanced
|
||||
algorithms (even good-old AI slop :-).
|
||||
|
||||
Below is a quick snippet that shows how to use the Trie class to implement
|
||||
a poor-man's autocomplete without using a language server. This snippet
|
||||
was taken from the [example application](../example/) so can see it in
|
||||
context.
|
||||
|
||||
```c++
|
||||
void Editor::setAutocompleteMode(bool flag) {
|
||||
// see we are turning autocomplete on or off
|
||||
if (flag) {
|
||||
// rebuild word list
|
||||
buildAutocompleteTrie();
|
||||
|
||||
// setup autocomplete by submitting a new configuration
|
||||
TextEditor::AutoCompleteConfig config;
|
||||
|
||||
config.callback = [this](TextEditor::AutoCompleteState& state) {
|
||||
trie.findSuggestions(state.suggestions, state.searchTerm);
|
||||
};
|
||||
|
||||
editor.SetAutoCompleteConfig(&config);
|
||||
|
||||
// enable change tracking
|
||||
// we don't track every keystroke, callbacks can be delayed up to 3000 milliseconds
|
||||
// if you want live tracking, change 3000 to 0 (performance hit will be minimal for small documents)
|
||||
editor.SetChangeCallback([this]() {
|
||||
buildAutocompleteTrie();
|
||||
}, 3000);
|
||||
|
||||
} else {
|
||||
// disable autocomplete and change tracking
|
||||
editor.SetAutoCompleteConfig(nullptr);
|
||||
editor.SetChangeCallback(nullptr);
|
||||
}
|
||||
}
|
||||
|
||||
void Editor::buildAutocompleteTrie() {
|
||||
// empty list first
|
||||
trie.clear();
|
||||
|
||||
// add language words (if required)
|
||||
auto language = editor.GetLanguage();
|
||||
|
||||
if (language) {
|
||||
for (auto& word : language->keywords) { trie.insert(word); }
|
||||
for (auto& word : language->declarations) { trie.insert(word); }
|
||||
for (auto& word : language->identifiers) { trie.insert(word); }
|
||||
}
|
||||
|
||||
// add all identifiers in current document
|
||||
editor.IterateIdentifiers([this](const std::string& identifier) {
|
||||
trie.insert(identifier);
|
||||
});
|
||||
}
|
||||
```
