CHANGELOG.markdown

Change Log

Unreleased

• MSRV is now 1.54. We soft-updated to this in 0.8.0 with a feature min-const-generics, which has now been removed (and as such, we resume having no default features).

• Upgraded from Dear ImGui 1.84.2 to 1.86. See the 1.85 and the 1.86 release notes

• BREAKING: Removed push_style_colors and push_style_vars. Instead, use push_style_color in a loop. This was deprecated in 0.7.0 and should have been removed in 0.8.0. This also removes their associated tokens.

• BREAKING: Ui now does not have a lifetime associated with it, but is only ever given to users in the form of &mut Ui. Additionally, the render function has been moved to the Context instead of Ui.

• BREAKING: SharedFontAtlas now hides an Rc within its wrapper -- this simplifies the codebase and more accurately reflects how we expect SharedFontAtlas to be used (ie, you're probably going to set it up once, and then give it around, rather than constantly edit it). SharedFontAtlas users, if this change is very bad for you, please let us know with issues!

• BREAKING: Id is now a simpler facade, but requires the Ui struct to generate. push_id, equally, has been split into multiple functions for simplicity. New example imgui-examples/examples/id_wrangling.rs shows some of the push_id usage

• Added imgui-sdl2-support to provide a simple ImGui platform wrapper. Please give it a try! Thank you to @NightShade256 for implementing this here

• BREAKING: We now only support glium 0.30. We're in a difficult position supporting arbitrary glium versions in our renderer, since glium is only in a semi-maintained state. glium users, please get in contact in issues to let us know what will work best for your needs!

• Added InputScalar and InputScalarN. These are the core Input modules that Dear ImGui uses, and ultimately what InputFloat and InputInt turn into. See deprecation of InputFloat and InputInt as a result. Thank you to @EmbersArc for implementing this here.

• BREAKING: ui.input_int and ui.input_float now return InputScalar<'ui, 'l, f32/i32>, instead of InputFloat/InputInt. This struct has all of the same flags as InputFloat and InputInt did.

• DEPRECATED: InputFloat and InputInt have been deprecated. ui.input_float and ui.input_int are not, however, and instead will just call input_scalar as appropriate. Therefore, please switch your code to ui.input_float or ui.input_int.

• Added add_polyline method to DrawListMut, which binds to Dear ImGui's AddPolyline and AddConvexPolyFilled

• BREAKING: The following structs have had their new method changed and deprecated; they now also take ui in their new, but you should create them on the Ui struct instead.

  • Window should be made with ui.window - e.g ui.window("My Window").build(|| { ui.text("Contents") });
  • ChildWindow should be made with ui.child_window
  • MenuItem should be made with ui.menu_item or ui.menu_item_config.
  • DragDropSource and DragDropTarget should be made with ui.drag_drop_source_config or ui.drag_drop_target. Both of these methods, and the DragDrop API in general, are likely to change.

• Added docking feature which builds against the upstream docking branch. Only basic API is exposed currently, just enough to enable the docking imgui_context.io_mut().config_flags |= imgui::ConfigFlags::DOCKING_ENABLE; - a safe API for programtically docking windows and so on will be added later (until then the internal docking API can be accessed, imgui::sys::igDockBuilderDockWindow and so on)

• Fixed dpi related issues when not in HiDpiMode::Default mode. The wrong scale factor was used when converting winit physical size to logical size, causing the imgui display size to be incorrect.

0.8.0 - 2021-09-17

Welcome to the 0.8.0 update. This is one of the largest updates imgui-rs has ever seen; it will generate errors in a 0.7 project, but hopefully it should be both quick to fix, and enjoyable to update. See our release page for more information and a list of contributors to this cycle. Thank you to everyone who uses imgui-rs, files issues, and spend their time and effort to PR new changes into the codebase. Because of all that effort, this is by far the best imgui-rs has looked!

• Removed ImStr and ImString from the API. Currently im_str! is deprecated and will be removed in 0.9.0. To change your code:

  • If you were just wrapping a string literal, like im_str!("button"), just use "button". (Help: the regex im_str!\("((?:(?=(\\?))\2.)*?)"\), replacing matches with "$1", can get the majority of these quickly.);
  • If you were formatting, like &im_str!("My age is {}", 100), you can now just use format like format!("My age is {}, 100). Notice that due to the trait bounds, you can pass the string in directly too.

• BREAKING: Most tokens through the repository (eg. WindowToken, TabBarToken, FontStackToken, etc) now allow for permissive dropping -- i.e, you don't need to actually call the .end() method on them anymore. In exchange, these tokens have taken on a lifetime, which allows them to be safe. This could make some patterns impossible. Please file an issue if this causes a problem.

  • end() no longer takes Ui. This is a breaking change, but hopefully should be trivial (and perhaps nice) for users to fix. Simply delete the argument, or add a _ before the token's binding name and allow it to be dropped on its own. In our code, we tend to write these now like:

if let Some(_t) = ui.begin_popup("example") {
  // your code here
}

• BREAKING: Created with_x variants for most functions which previously took multiple parameters where some had default arguments in the C++. This makes calling most functions simpler and more similar to the C++.

  • The most likely breaking changes users will see is button and same_line now take one fewer parameter -- if you were calling button with [0.0, 0.0], simply delete that -- otherwise, call button_with_size. Similarly, for same_line, if you were passing in 0.0. simply delete that argument. Otherwise, call same_line_with_pos.

• ADDED: support for the tables API which was added in dear imgui 1.80. We currently have this feature gated behind tables-api. You should feel safe to use this in stable production, but be aware of two things:

  1. The tables API is marked as "beta" meaning that it may change with fewer stability promises. This is unlikely and it seems fairly settled.
  2. There are a few cases where the tables API will segfault by dereferencing a NULL where it should instead ASSERT and crash. This is simply annoying because you won't get a stacktrace. See here for more info on that.. If this is fixed upstream, we will issue a patch.

• ADDED: an imgui-glow-renderer which targets glow 0.10. Before release, this will be updated to target current 0.11 glow when further features are added. Thank you to @jmaargh for the work implementing this here!

• UPGRADED: from v1.80 to Dear ImGui v1.84.2 See the Dear ImGui v1.84 release notes for more information. Thank you to @dbr for doing the work (twice actually) of upgrading the repository.

• BREAKING: Reworked how callbacks on InputText and InputTextMultiline work.

  • REMOVED .callback_name() methods in favor of one method: .callback(FLAGS, CallbackStruct).
  • Wrapped callback kinds into their own enums, InputTextCallback and InputTextCallbackMultiline.
  • Created a trait, InputTextCallbackHandler.
  • To see how to create an InputText callback, see examples/text_callback.rs.
  • Finally, please note that editing an &mut String which contains \0 within it will produce surprising truncation within ImGui. If you need to edit such a string, please pre-process it.

• ADDED: begin_disable and begin_enable methods. These add (finally) support for disabling any widget. Thank you to @dbr for implementing this here.

• BREAKING: MSRV is now 1.54. This is gives us access to min-const-generics, which we use in a few places, but will gradually use more. Because this is the first time we've bumped MSRV intentionally, we have added a new feature min-const-generics, which is enabled by default. If you are pre-1.54, you can hang onto this update by disabling that feature. In our next update, this feature will be removed and we will commit to our MSRVs going forward. Thank you to @dbr for changing our CI infrastructure to support better MSRVs here.

• BREAKING: Changed default version of Winit in imgui-winit-support to winit 0.25. Thank you to @repi for implementing this here.

  • Removed automatically adding default features for imgui-winit-support with the exception of the current default winit feature/dep version. If you want to not have the default features of winit with 0.25, set default-features = false and add winit-25 as a normal feature. Thank you to @dzil123 for the work implementing this here!

• ADDED: Support for the freetype font rasterizer. Enabled by the non-default freetype feature, e.g imgui = {version = "...", features=["freetype"]}) Thank you to @dbr for this work implementing this here.

• ADDED: doc alias support throughout the repository. You can now, inside the docs, search for imgui-rs functions by their Dear ImGui C++ names. For example, searching for InputText will pull up Ui::input_text. This was quite a lot of documentation and effort, so thank you to @toyboot4e for implementing this here.

• ADDED: text hinting into InputText. Thank you to @lwiklendt for implementing this here.

• BREAKING: Reworked .range calls on Slider, VerticalSlider, and Drag to simply take two min and max values, and requires that they are provided in the constructor.

  • To update without changing behavior, use the range T::MIN and T::MAX for the given numerical type (such as i8::MIN and i8::MAX).
  • Using .range is still maintained for simplicity, but will likely be deprecated in 0.9 and removed in 0.10!

• DrawListMut has new methods to draw images

  • The methods are add_image, add_image_quad, and add_image_rounded. The imgui-examples/examples/custom_textures.rs has been updated to show their usage.
  • Additionally the imgui::draw_list module is now public, which contains the various draw list objects. While the add_* methods are preferred, imgui::draw_list::Circle::new(&draw_list_mut, ...).build() is equivalent
  • Finally, we have relaxed the limits around having multiple draw lists such that you can have multiple mutable draw lists of different kinds (ie, a foreground and a background at the same time.).
  • Thank you to @dbr for implementing these changes.

• ADDED: the ButtonFlags which previously prevented invisible_button from being usable. Thank you to @dbr for implementing this change here.

• BREAKING: PopupModal's new was reworked so that it didn't take Ui until build was called. This is a breaking change if you were invoking it directly. Simply move your ui call to build or begin.

• BREAKING: Restored methods to access keyboard based on backend-defined keyboard map indexes. These allow access to most keys, not just those defined in the small subset of imgui::Keys (note the available keys may be expanded in future by imgui PR #2625)

  • The new methods on imgui::Ui are is_key_index_down, is_key_index_pressed, is_key_index_pressed_no_repeat, is_key_index_released, is_key_index_released
  • For example ui.is_key_released(imgui::Key::A) is same as ui.is_key_index_released(winit::events::VirtualKeyCode::A as i32) when using the winit backend

• BREAKING: Modifies build style methods to allow the provide closure to return a value. The build call will then return Some(value) if the closure is called, and None if it isn't.

  • The most likely breaking changes users will see is that they will need to add semicolons after calling build, because these function no longer return ().
  • Thank you to @AngelOfSol for implementing this here.

• BREAKING: Removed imgui::legacy which contained the old style of flags. The remaining flags in imgui::legacy have been updated to be consistent with other flags in the project.

  • imgui::legacy::ImGuiDragDropFlags were accidentally not cleared when they were remade in drag_drop.rs in v0.7.0.
  • imgui::legacy::ImGuiInputTextFlags is now imgui::input_widgets::InputTextFlags
  • imgui::legacy::ImGuiTreeNodeFlags is now imgui::widget::tree::TreeNodeFlags
  • imgui::legacy::ImDrawListFlags is now imgui::draw_list::DrawListFlags

• Full (32-bit) unicode support is enabled in Dear Imgui (e.g. -DIMGUI_USE_WCHAR32 is enabled now). Previously UTF-16 was used internally.

  • BREAKING: Some parts of the font atlas code now use char (or u32) instead of u16 to reflect this.
    • Note: u32 is used over char in some situations, such as when surrogates are allowed
  • BREAKING (sorta): Dear Imgui now will use 32 bits for character data internally. This impacts the ABI, including sizes of structs and such, and can break some low level or advanced use cases:
    • If you're linking against extensions or plugins to Dear Imgui not written in Rust, you need to ensure it is built using -DIMGUI_USE_WCHAR32.
      • However, if the DEP_IMGUI_DEFINE_ vars are used properly, this is non-breaking.
    • If you're using features="wasm" to "link" against emscripten-compiled Dear Imgui, you need to ensure you use -DIMGUI_USE_WCHAR32 when compile the C and C++ code.
      • If you're using DEP_IMGUI_DEFINE_s for this already, then no change is needed.
    • If you're using .cargo/config to apply a build script override and link against a prebuilt Dear Imgui (or something else along these lines), you need to ensure you link with a version that was built using -DIMGUI_USE_WCHAR32.

0.7.0 - 2021-02-04

• Upgrade to Dear ImGui v1.80. (Note that the new table functionality is not yet supported, however)

• Ui::key_index() is now called internally when needed, and the various is_key_foo now take a Key directly: imgui-rs#416

  • is_key_down, is_key_pressed, is_key_released and key_pressed_amount now take a Key instead of u32 (breaking).
  • key_index is no longer public (breaking). If you need access to the key map, it can be accessed as ui.io().key_map[key] (If you need to do this, file a bug, since I'm open to exposing this if there's actually a use case).

• winit 0.23/0.24 handling has been (hopefully) fixed: imgui-rs#420 (breaking, see also imgui-rs#412).

  • imgui-winit-support's winit-23 feature no longer supports winit version 0.24 (this caused an unintentional semver breakage before, unfortunately).
  • imgui-winit-support has a new winit-24 feature for 0.24 support.
  • By default imgui-winit-support feature now enables winit-24, and not winit-23 (by default it will always enable the latest).

• The imgui crate no longer depends on gfx or glium directly: imgui-rs#420 (breaking, related to the previous change).

  • That is, the gfx and glium features are removed to reduce version compatibility issues going forward.
    • This only matters if you manually implement gfx or glium renderers without using the imgui-glium-renderer or imgui-gfx-renderer crates.
    • In the (somewhat unlikely) case you were relying on these this, you should define your own vertex type that's layout-compatible with imgui::DrawVert, and replace calls to imgui::DrawList::vtx_buffer() with imgui::DrawList::transmute_vtx_buffer::<MyDrawVert>(). You can see imgui_glium_renderer::GliumDrawVert and imgui_gfx_renderer::GfxDrawVert types respectively for examples of this, if needed, but it should be straightforward enough if you're already implementing a renderer from scratch.
  • This is admittedly less convenient, but avoids depending on any specific version of gfx or glium in the core imgui crate, which will ease maintenance and reduce unintentional breakage in the future.

• Non-window DrawList support has been fixed/improved: imgui-rs#414

  • WindowDrawList has been renamed to DrawListMut, to reflect that it may refer to other kinds of draw lists, and is mutable, unlike imgui::DrawList (breaking).
  • Ui::get_background_draw_list() has been fixed when used outside of a window context, and now has an example.
  • Ui::get_foreground_draw_list() has been added, analogous to Ui::get_background_draw_list().

• Added drag drop support, with a safe and an unsafe variant: imgui-rs#428

  • DragDropSource allows users to create a dragdrop payload which is either empty, of 'static + Copy data, or unsafe, allowing for theoretically arbitrary payloads.
  • DragDropTarget allows users to accept any of the above payloads.
  • Extensive documentation has been made on all of these features, hopefully as a target for future features.

• ImColor (which is a wrapper around u32) has been renamed to ImColor32 in order to avoid confusion with the ImColor type from the Dear ImGui C++ code (which is a wrapper around ImVec4). In the future an ImColor type which maps more closely to the C++ one will be added.

  • Additionally, a number of constructor and accessor methods have been added to it ImColor, which are const fn where possible.

• The im_str! macro can now be used in const contexts (when the format! version is not used).

• im_str! now verifies that the parameter has no interior nuls at compile time. This can be avoided to get the old (truncating) behavior by forcing it to use the format!-like version, e.g. im_str!("for_some_reason_this_should_be_truncated\0 there {}", "").

  • This is not recommended, and is probably not useful.

• Many functions are now const fn.

• A large number of small functions are now #[inline], but many still aren't, so you probably will want to build with LTO for release builds if you use imgui heavily.

• The io.config_windows_memory_compact_timer flag has been renamed to io.config_memory_compact_timer. This follows the similar rename in the C++ ImGui, and was done because it no longer only applies to window memory usage.

• The variants of ColorEditInputMode and ColorEditDisplayMode have been renamed to be CamelCase instead of upper case (e.g. ColorEditFooMode::RGB => ColorEditFooMode::Rgb).

  • However, this change is probably not breaking (in practice if not in theory) because const aliases using the old names are provided.

0.6.1 - 2020-12-16

• Support for winit 0.24.x
  • Note: this change was accidentally semver-breaking, see the caveat below.
• Support multiple simultaneous winit versions in imgui-winit-support:
  • The latest will be if more than one is specified, and a single warning will be logged in debug builds (based on cfg!(debug_assertions)) at runtime if multiple are specified.
  • This is intended to make features behave a bit more closely to additively, and reduce the pain of using this crate in a larger workspace.
• Avoid dropping mouse events when press/release are on the same frame (macos)
• Substantial repository layout reorganization

Caveat: Semver broken in 0.6.1 in imgui-winit-support

Note from the future: [email protected] has been yanked. I don't believe the breakage impacted the other crates so I'm leaving those to avoid impacting non-winit usages.

This release accidentally broke semver, and should have been 0.7.0. It will be yanked when 0.7.0 is released, unless there are objections.

This happened when updating the glium/winit/glium versions, adding support for winit 0.24 and related. Unfortunately, while an attempt to avoid breakage was made, it happened regardless. This mainly happened as it was the holidays and not enough attention was paid to the changes in an urgent-sounding request for supporting the new version, and more care will be taken in the future to avoid cutting a hasty release without adequate testing.

As mentioned, the 0.6.1 release of imgui-winit-support has been yanked.

Changed

• Button, selectable, histogram, plotlines, and progress bar accept size with Into<ImVec2>
• ImString::new always succeeds and any interior NULs truncate the string. Breaking change
• All builder constructor functions (e.g. Window::new) now take &Ui reference to tie the lifetime of the builder to it.
• Bumped minimum Rust version to 1.17 because some dependencies require it.
