# Old Announcements
* **29 May 2016**
* **Alpha 3 is here!** Get it [here](https://github.com/andlabs/libui/releases/tag/alpha3).
* The next packaged release will introduce:
* uiGrid, another way to lay out controls, a la GtkGrid
* uiOpenGLArea, a way to render OpenGL content in a libui uiArea
* uiTable, a data grid control that may or may not have tree facilities (if it does, it will be called uiTree instead)
* a complete, possibly rewritten, drawing and text rendering infrastructure
* **24 May 2016**
* You can now help choose [a potential new build system for libui](https://github.com/andlabs/libui/issues/62).
* Tomorrow I will decide if OS X 10.7 will also be dropped alongside GTK+ 3.4-3.8 this Saturday. Stay tuned.
* **22 May 2016**
* Two more open questions I'd like your feedback on are available [here](https://github.com/andlabs/libui/issues/48) and [here](https://github.com/andlabs/libui/issues/25).
* Sometime in the next 48 hours (before 23:59 EDT on 24 May 2016) I will split `uiCombobox` into two separate controls, `uiCombobox` and `uiEditableCombobox`, each with slightly different events and "selected item" mechanics. Prepare your existing code.
* **21 May 2016**
* I will now post announcements and updates here.
* Now that Ubuntu 16.04 LTS is here, no earlier than next Saturday, 28 May 2016 at noon EDT, **I will bump the minimum GTK+ version from 3.4 to 3.10**. This will add a lot of new features that I can now add to libui, such as search-oriented uiEntries, lists of arbitrary control layouts, and more. If you are still running a Linux distribution that doesn't come with 3.10, you will either need to upgrade or use jhbuild to set up a newer version of GTK+ in a private environment.
* You can decide if I should also drop OS X 10.7 [here](https://github.com/andlabs/libui/issues/46).

# Contributing to libui
libui is an open source project that openly accepts contributions. I appreciate your help!
## Rules for contributing code
While libui is open to contributions, a number of recent, significantly large contributions and uncontributed forks have recently surfaced that do not present themselves in a form that makes it easy for libui to accept them. In order to give your contribution a high chance of being accepted into libui, please keep the following in mind as you prepare your contribution.
### Commit messages and pull request description
libui does not enforce rules about the length or detail that a commit message. I'm not looking for an essay. However, single-word descriptions of nontrivial changes are *not* acceptable. I should be able to get a glimpse of what a commit does from the commit message, even if it's just one sentence to describe a trivial change. (Yes, I know I haven't followed this rule strictly myself, but I try not to break it too.) And a commit message should encompass everything; typically, I make a number of incremental commits toward a feature, so the commit messages don't have to be too long to explain everything.
Your pull request description, on the other hand, must be a summary of the sum total of all the changes made to libui. Don't just drop a pull request on me with a one-line-long elevator pitch of what you added. Describe your proposed API changes, implementation requirements, and any important consequences of your work.
### Code formatting
libui uses K&R C formatting rules for overall code structure: spaces after keywords like `if`, `{` on the same line as a statement with a space, `{` on its own line after a function or method signature (even those inside the class body), no space after the name of a function, etc.
Use hard tabs, NOT spaces, for indentation. I use a proportional-width font and my text editor doesn't set tabs to a multiple of the space width, so I *will* be able to tell. If you use a fixed-width font, I suggest setting a tab width of 4 spaces per tab, but don't put diagrams in comments with hard tabs, because not everyone does this.
Expressions should have a space around binary operators, and use parentheses where it would help humans gather the meaning of an expression, regardless of whether a computer could tell what is correct.
When breaking expressions into multiple lines, always break *after* an operator, such as `,` or `&&`.
There should be a newline between a function's variables and a function's code. After that, you can place newlines to delimit different parts of a function, but don't go crazy.
In the event you are unsure of something, refer to existing libui code for examples. I may wind up fixing minor details later anyway, so don't fret about getting minor details right the first time.
### Naming
libui uses camel-case for naming, with a handful of very specific exceptions (namely GObject method names, where GObject itself enforces the naming convention).
All public API names should begin with `ui` and followed by a capital letter. All public struct field names should begin with a capital letter. This is identical to the visibiilty rules of Go, assuming a package name of `ui`.
Private API names — specifcally those used by more than one source file — should begin with `uipriv` and be followed by a capital letter. This avoids namespace collisions in static libraries.
Static functions and static objects do not have naming restrictions.
Acronyms should **NOT** be mixed-case. `http` for the first word in a camel-case name, `HTTP` for all else, but **NEVER** `Http`. This is possibly the only aspect of the controversial nature of code style that I consider indefensibly stupid.
### API documentation
(TODO I am writing an API documentation tool; once that becomes stable enough I can talk about documenting libui properly. You'll see vestiges of it throughout ui.h, though.)
### Other commenting
(TODO write this part)
### Compatibility
libui takes backward compatibility seriously. Your code should not break the current compatibility requirements. All platforms provide a series of macros, defined in the various `uipriv_*.h` files (or `winapi.hpp` on Windows), that specify the minimum required version. If you find yourself needing to remove these or ignore resultant warnings or errors, you're probably breaking compatibility.
Choosing to drop older versions of Windows, GTK+, and OS X that I could have easily continued to support was not done lightly. If you want to discuss dropping support for an older version of any of these for the benefit of libui, file an issue pleading your case (see below).
GTK+ versions are harder to drop because I am limited by Linux distribution packaging. In general, I will consider bumping GTK+ versions on a new Ubuntu LTS release, choosing the earliest version available on the major distributions at the time of the *previous* Ubuntu LTS release. As of writing, the next milestone will be *after* April 2018, and the target GTK+ version appears to be 3.18, judging by Ubuntu 16.04 LTS alone. This may be bumped back depending on other distros (or it may not be bumped at all), but you may wish to keep this in mind as you write.
(TODO talk about future.c/.cpp/.m files)
As for language compatibility, libui is written in C99. I have no intention of changing this.
As for build system compatibility, libui uses CMake 3.1.0. If you wish to bump the version, file an issue pleading your case (but see below).
**If you do plead your case**, keep in mind that "it's old" is not a sufficient reason to drop things. If you can prove that **virtually no one** uses the minimum version anymore, then that is stronger evidence. The best evidence, however, is that not upgrading will hold libui back in some significant way — but beware that there are some things I won't add to libui itself.
### Windows-specific notes
The Windows backend of libui is written in C++ using C++11.
Despite using C++, please refrain from using the following:
- using C++ in ui_windows.h (this file should still be C compatible)
- smart pointers
- namespaces
- `using namespace`
- ATL, MFC, WTL
The following are not recommended, for consistency with the rest of libui:
- variable declarations anywhere in a function (keep them all at the top)
- `for (int x...` (C++11 foreach syntax is fine, though)
- omitting the `struct` on type names for ordinary structs
The format of a class should be
```c++
class name : public ancestor {
int privateVariable;
// etc.
public:
// public stuff here
};
```
### GTK+-specific notes
Avoid GNU-specific language features. I build with strict C99 conformance.
### OS X-specific notes
Avoid GNU-specific/clang-specific language features. I build with strict C99 conformance.
libui is presently **not** ARC-compliant. Features that require ARC should be avoided for now. I may consider changing this in the future, but it will be a significant change.
To ensure maximum compiler output in the event of a coding error, there should not be any implicit method calls in Objective-C code. For instance, don't do
```objective-c
[[array objectAtIndex:i] method]
```
Instead, cast the result of `objectAtIndex:` to the appropriate type, and then call the method. (TODO learn about, then decide a policy on, soft-generics on things other than `id`)
The format of a class should be
```objective-c
@interface name : parent<protocols> {
// ivars
}
// properties
- (ret)method:(int)arg;
// more methods
@end
@implementation name
- (ret)method:(int)arg
{
// note the lack of semicolon
}
@end
```

# Old Updates
* **29 May 2016**
* Thanks to @pcwalton, we can now statically link libui! Simply do `make STATIC=1` instead of just `make`.
* On Windows you must link both `libui.lib` and `libui.res` AND provide a Common Controls 6 manifest for output static binaries to work properly.
* **28 May 2016**
* As promised, **the minimum system requirements are now OS X 10.8 and GTK+ 3.10 for OS X and Unix, respectively**.
* **26 May 2016**
* Two OS X-specific functions have been added: `uiDarwinMarginAmount()` and `uiDarwinPaddingAmount()`. These return the amount of margins and padding, respectively, to give to a control, and are intended for container implementations. These are suitable for the constant of a NSLayoutConstraint. They both take a pointer parameter that is reserved for future use and should be `NULL`.
* **25 May 2016**
* uiDrawTextLayout attributes are now specified in units of *graphemes* on all platforms. This means characters as seen from a user's perspective, not Unicode codepoints or UTF-8 bytes. So a long string of combining marker codepoints after one codepoint would still count as one grapheme.
* **24 May 2016**
* As promised, `uiCombobox` is now split into `uiCombobox` for non-editable comboboxes and `uiEditableCombobox` for editable comboboxes. Mind the function changes as well :)
* There is a new function `uiMainStep()`, which runs one iteration of the main loop. It takes a single boolean argument, indicating whether to wait for an event to occur or not. It returns true if an event was processed (or if no event is available if you don't want to wait) and false if the event loop was told to stop (for instance, `uiQuit()` was called).
* **23 May 2016**
* Fixed surrogate pair drawing on OS X.
* **22 May 2016**
* Removed `uiControlVerifyDestroy()`; that is now part of `uiFreeControl()` itself.
* Added `uiPi`, a constant for π. This is provided for C and C++ programmers, where there is no standard named constant for π; bindings authors shouldn't need to worry about this.
* Fixed uiMultilineEntry not properly having line breaks on Windows.
* Added `uiNewNonWrappingMultilineEntry()`, which creates a uiMultilineEntry that scrolls horizontally instead of wrapping lines. (This is not documented as being changeable after the fact on Windows, hence it's a creation-time choice.)
* uiAreas on Windows and some internal Direct2D areas now respond to `WM_PRINTCLIENT` properly, which should hopefully increase the quality of screenshots.
* uiDateTimePicker on GTK+ works properly on RTL layouts and no longer disappears off the bottom of the screen if not enough room is available. It will also no longer be marked for localization of the time format (what the separator should be and whether to use 24-hour time), as that information is not provided by the locale system. :(
* Added `uiUserBugCannotSetParentOnToplevel()`, which should be used by implementations of toplevel controls in their `SetParent()` implementations. This will also be the beginning of consolidating common user bug messages into a single place, though this will be one of the only few exported user bug functions.
* uiSpinbox and uiSlider now merely swap their min and max if min ≥ max. They will no longer panic and do nothing, respectively.
* Matrix scaling will no longer leave the matrix in an invalid state on OS X and GTK+.
* `uiMultilineEntrySetText()` and `uiMutlilineEntryAppend()` on GTK+ no longer fire `OnChanged()` events.

# Old News
* **27 November 2016**
* Decided to split the table stuff into its own branch. It will be developed independently of everything else, along with a few other features.
* **2 November 2016**
* Added two new functions to replace the deleted `uiWindowPosition()` and friends: `uiAreaBeginUserWindowMove()` and `uiAreaBeginUserWindowResize()`. When used in a `uiAreaHandler.Mouse()` event handler, these let you initiate a user-driven mouse move or mouse resize of the window at any point in a uiArea.
* **31 October 2016**
* @krakjoe noticed that I accidentally used thread-unsafe code in uiQueueMain() on Unix. Fixed.
* **24 October 2016**
* `uiWindowSetContentSize()` on Unix no longer needs to call up the GTK+ main loop. As a result, bugs related to strange behavior using that function (and the now-deleted `uiWindowSetPosition()` and `uiWindowCenter()`) should go away. I'll need to go through the bugs to verify as much, though.
* **22 October 2016**
* Due to being unable to guarantee they will work (especially as we move toward capability-driven window systems like Wayland), or being unable to work without hacking that breaks other things, the following functions have been removed: `uiWindowPosition()`, `uiWindowSetPosition()`, `uiWindowCenter()`, and `uiWindowOnPositionChanged()`. Centering may come back at some point in the future, albeit in a possibly restricted form. A function to initiate a user move when a part of a uiArea is clicked will be provided soon.
* **21 October 2016**
* `uiDrawTextWeightUltraBold` is now spelled correctly. Thanks to @krakjoe.
* **18 June 2016**
* Help decide [the design of tables and trees in libui](https://github.com/andlabs/libui/issues/159); the implementation starts within the next few days, if not tomorrow!
* **17 June 2016**
* **CMake 3.1.0 is now required.** This is due to CMake's rapid development pace in the past few years adding things libui needs to build on as many systems as possible. If your OS is supported by libui but its repositories ship with an older version of CMake, you will need to find an updated one somewhere.
* Please help [plan out a better menu API](https://github.com/andlabs/libui/issues/152).
* `uiMainSteps()` no longer takes any arguments and no longer needs to invoke a function to do the work. You still need to call it, but once you do, it will return immediately and you can then get right to your main loop.
* **CMake 3.1.0 is now required.** This is due to CMake's rapid development pace in the past few years adding things libui needs to build on as many systems as possible. If your OS is supported by libui but its repositories ship with an older version of CMake, you will need to find an updated one somewhere.
* Added `uiNewVerticalSeparator()` to complement `uiNewHorizontalSeparator()`.
* **16 June 2016**
* Added `uiWindowContentSize()`, `uiWindowSetContentSize()`, and `uiWindowOnContentSizeChanged()` methods for manipulating uiWindow content sizes. Note the use of "content size"; the size you work with does NOT include window decorations (titlebars, menus, etc.).
* Added `uiWindowFullscreen()` and `uiWindowSetFullscreen()` to allow making fullscreen uiWindows, taking advantage of OS facilities for fullscreen and without changing the screen resolution (!).
* Added `uiWindowBorderless()` and `uiWindowSetBorderless()` for allowing borderless uiWindows.
* Added `uiMainSteps()`. You call this instead of `uiMain()` if you want to run the main loop yourself. You pass in a function that will be called; within that function, you call `uiMainStep()` repeatedly until it returns 0, doing whatever you need to do in the meantime. (This was needed because just having `uiMainStep()` by itself only worked on some systems.)
* Added `uiProgressBarValue()` and allowed passing -1 to `uiProgressBarSetValue()` to make an indeterminate progress bar. Thanks to @emersion.
* **15 June 2016**
* Added `uiFormDelete()`; thanks to @emersion.
* Added `uiWindowPosition()`, `uiWindowSetPosition()`, `uiWindowCenter()`, and `uiWindowOnPositionChanged()`, methods for manipulating uiWindow position.
* **14 June 2016**
* uiDarwinControl now has a `ChildVisibilityChanged()` method and a corresponding `NotifyVisibilityChanged()` function that is called by the default show/hide handlers. This is used to make visibility changes work on OS X; uiBox, uiForm, and uiGrid all respect these now.
* The same has been done on the Windows side as well.
* Hiding and showing controls and padding calculations are now correct on Windows at long last.
* Hiding a control in a uiForm now hides its label on all platforms.
* **13 June 2016**
* `intmax_t` and `uintmax_t` are no longer used for libui API functions; now we use `int`. This should make things much easier for bindings. `int` should be at least 32 bits wide; this should be sufficient for all but the most extreme cases.
* **12 June 2016**
* Added `uiGrid`, a new container control that arranges controls in rows and columns, with stretchy ("expanding") rows, stretchy ("expanding") columns, cells that span rows and columns, and cells whose content is aligned in either direction rather than just filling. It's quite powerful, is it? =P
* **8 June 2016**
* Added `uiForm`, a new container control that arranges controls vertically, with properly aligned labels on each. Have fun!
* **6 June 2016**
* Added `uiRadioButtonsSelected()`, `uiRadioButtonsSetSelected()`, and `uiRadioButtonsOnSelected()` to control selection of a radio button and catch an event when such a thing happens.
* **5 June 2016**
* **Alpha 3.1 is here.** This was a much-needed update to Alpha 3 that changes a few things:
* **The build system is now cmake.** cmake 2.8.11 or higher is needed.
* Static linking is now fully possible.
* MinGW linking is back, but static only.
* Added `uiNewPasswordEntry()`, which creates a new `uiEntry` suitable for entering passwords.
* Added `uiNewSearchEntry()`, which creates a new `uiEntry` suitable for searching. On some systems, the `OnChanged()` event will be slightly delayed and/or combined, to produce a more natural feel when searching.
* **29 May 2016**
* **Alpha 3 is here!** Get it [here](https://github.com/andlabs/libui/releases/tag/alpha3).
* The next packaged release will introduce:
* uiGrid, another way to lay out controls, a la GtkGrid
* uiOpenGLArea, a way to render OpenGL content in a libui uiArea
* uiTable, a data grid control that may or may not have tree facilities (if it does, it will be called uiTree instead)
* a complete, possibly rewritten, drawing and text rendering infrastructure
* Thanks to @pcwalton, we can now statically link libui! Simply do `make STATIC=1` instead of just `make`.
* On Windows you must link both `libui.lib` and `libui.res` AND provide a Common Controls 6 manifest for output static binaries to work properly.
* **28 May 2016**
* As promised, **the minimum system requirements are now OS X 10.8 and GTK+ 3.10 for OS X and Unix, respectively**.
* **26 May 2016**
* Two OS X-specific functions have been added: `uiDarwinMarginAmount()` and `uiDarwinPaddingAmount()`. These return the amount of margins and padding, respectively, to give to a control, and are intended for container implementations. These are suitable for the constant of a NSLayoutConstraint. They both take a pointer parameter that is reserved for future use and should be `NULL`.
* **25 May 2016**
* uiDrawTextLayout attributes are now specified in units of *graphemes* on all platforms. This means characters as seen from a user's perspective, not Unicode codepoints or UTF-8 bytes. So a long string of combining marker codepoints after one codepoint would still count as one grapheme.
* **24 May 2016**
* You can now help choose [a potential new build system for libui](https://github.com/andlabs/libui/issues/62).
* Tomorrow I will decide if OS X 10.7 will also be dropped alongside GTK+ 3.4-3.8 this Saturday. Stay tuned.
* As promised, `uiCombobox` is now split into `uiCombobox` for non-editable comboboxes and `uiEditableCombobox` for editable comboboxes. Mind the function changes as well :)
* There is a new function `uiMainStep()`, which runs one iteration of the main loop. It takes a single boolean argument, indicating whether to wait for an event to occur or not. It returns true if an event was processed (or if no event is available if you don't want to wait) and false if the event loop was told to stop (for instance, `uiQuit()` was called).
* **23 May 2016**
* Fixed surrogate pair drawing on OS X.
* **22 May 2016**
* Two more open questions I'd like your feedback on are available [here](https://github.com/andlabs/libui/issues/48) and [here](https://github.com/andlabs/libui/issues/25).
* Sometime in the next 48 hours (before 23:59 EDT on 24 May 2016) I will split `uiCombobox` into two separate controls, `uiCombobox` and `uiEditableCombobox`, each with slightly different events and "selected item" mechanics. Prepare your existing code.
* Removed `uiControlVerifyDestroy()`; that is now part of `uiFreeControl()` itself.
* Added `uiPi`, a constant for π. This is provided for C and C++ programmers, where there is no standard named constant for π; bindings authors shouldn't need to worry about this.
* Fixed uiMultilineEntry not properly having line breaks on Windows.
* Added `uiNewNonWrappingMultilineEntry()`, which creates a uiMultilineEntry that scrolls horizontally instead of wrapping lines. (This is not documented as being changeable after the fact on Windows, hence it's a creation-time choice.)
* uiAreas on Windows and some internal Direct2D areas now respond to `WM_PRINTCLIENT` properly, which should hopefully increase the quality of screenshots.
* uiDateTimePicker on GTK+ works properly on RTL layouts and no longer disappears off the bottom of the screen if not enough room is available. It will also no longer be marked for localization of the time format (what the separator should be and whether to use 24-hour time), as that information is not provided by the locale system. :(
* Added `uiUserBugCannotSetParentOnToplevel()`, which should be used by implementations of toplevel controls in their `SetParent()` implementations. This will also be the beginning of consolidating common user bug messages into a single place, though this will be one of the only few exported user bug functions.
* uiSpinbox and uiSlider now merely swap their min and max if min ≥ max. They will no longer panic and do nothing, respectively.
* Matrix scaling will no longer leave the matrix in an invalid state on OS X and GTK+.
* `uiMultilineEntrySetText()` and `uiMutlilineEntryAppend()` on GTK+ no longer fire `OnChanged()` events.
* **21 May 2016**
* I will now post announcements and updates here.
* Now that Ubuntu 16.04 LTS is here, no earlier than next Saturday, 28 May 2016 at noon EDT, **I will bump the minimum GTK+ version from 3.4 to 3.10**. This will add a lot of new features that I can now add to libui, such as search-oriented uiEntries, lists of arbitrary control layouts, and more. If you are still running a Linux distribution that doesn't come with 3.10, you will either need to upgrade or use jhbuild to set up a newer version of GTK+ in a private environment.
* You can decide if I should also drop OS X 10.7 [here](https://github.com/andlabs/libui/issues/46).

## Status ## Announcements
It has come to my attention that I have not been particularly clear about how usable or feature-complete libui is, and that this has fooled many people into expecting more from libui right this moment than I have explicitly promised to make available. I apologize for not doing this sooner.
libui is currently **mid-alpha** software. Much of what is currently present runs stabily enough for the examples and perhaps some small programs to work, but the stability is still a work-in-progress, much of what is already there is not feature-complete, some of it will be buggy on certain platforms, and there's a lot of stuff missing. In short, here's a list of features that I would like to add to libui, but that aren't in yet:
- trees
- clipboard support, including drag and drop
- more and better dialogs
- printing
- accessibility for uiArea and custom controls
- document-based programs
- tighter OS integration (especially for document-based programs), to allow programs to fully feel native, rather than merely look and act native
- better support for standard dialogs and features (search bars, etc.)
- OpenGL support
In addition, [here](https://github.com/andlabs/libui/issues?utf8=%E2%9C%93&q=master+in%3Atitle+is%3Aissue+is%3Aopen) is a list of issues generalizing existing problems.
Furthermore, libui is not properly fully documented yet. This is mainly due to the fact that the API was initially unstable enough so as to result in rewriting documentation multiple times, in addition to me not being happy with really any existing C code documentation tool. That being said, I have started to pin down my ideal code documentation style in parts of `ui.h`, most notably in the uiAttributedString APIs. Over time, I plan on extending this to the rest of the headers. You can also use [the documentation for libui's Go bindings](https://godoc.org/github.com/andlabs/ui) as a reference, though it is somewhat stale and not optimally written.
But libui is not dead; I am working on it whenever I can, and I hope to get it to a point of real quality soon!
## News
*Note that today's entry (Eastern Time) may be updated later today.*
* **7 April 2019**
* **The build system has been switched to Meson.** See below for instructions. This change was made because the previous build system, CMake, caused countless headaches over trivial issues. Meson was chosen due to how unproblematic setting up libui's build just right was, as well as having design goals that are by coincidence closely aligned with what libui wants.
* Travis CI has been replaced with Azure Pipelines and much of the AppVeyor CI configuration was integrated into the Azure Pipelines configuration. This shouldn't affect most developers.
* **1 September 2018**
* **Alpha 4.1 is here.** This is an emergency fix to Alpha 4 to fix `uiImageAppend()` not working as documented. It now works properly, with one important difference you'll need to care about: **it now requires image data to be alpha-premultiplied**. In addition, `uiImage` also is implemented slightly more nicely now, and `ui.h` has minor documentation typo fixes.
* Alpha 4.1 also tries to make everything properly PIC-enabled.
* **10 August 2018**
* **Alpha 4 is finally here.** Everything from Alpha 3.5 and what's listed below is in this release; the two biggest changes are still the new text drawing API and new uiTable control. In between all that is a whole bunch of bugfixes, and hopefully more stability too. Thanks to everybody who helped contribute!
* Alpha 4 should hopefully also include automated binary releases via CI. Thanks to those who helped set that up!
* **8 August 2018**
* Finally introduced an API for loading images, `uiImage`, and a new control, `uiTable`, for displaying tabular data. These provide enough basic functionality for now, but will be improved over time. You can read the documentation for the new features as they are [here](https://github.com/andlabs/libui/blob/f47e1423cf95ad7b1001663f3381b5a819fc67b9/uitable.h). Thanks to everyone who helped get to this point, in particular @bcampbell for the initial Windows code, and to everyone else for their patience!
* **30 May 2018**
* Merged the previous Announcements and Updates section of this README into a single News section, and merged the respective archive files into a single NEWS.md file.
* **16 May 2018**
* Thanks to @parro-it and @msink, libui now has better CI, including AppVeyor for Windows CI, and automated creation of binary releases when I make a tagged release.
* **13 May 2018**
* Added new functions to work with uiDateTimePickers: `uiDateTimePickerTime()`, `uiDateTimePickerSetTime()`, and `uiDateTimePickerOnChanged()`. These operate on standard `<time.h>` `struct tm`s. Thanks @cody271!
* Release builds on Windows with MSVC should be fixed now; thanks @l0calh05t, @slahn, @mischnic, and @zentner-kyle.
* **12 May 2018**
* GTK+ and OS X now have a cleaner build process for static libraries which no longer has intermediate files and differing configurations. As a result, certain issues should no longer be present. New naming rules for internal symbols of libui have also started being drafted; runtime symbols and edge cases still need to be handled (and the rules applied to Windows) before this can become a regular thing.
* **2 May 2018**
* On Windows, you no longer need to carry around a `libui.res` file with static builds. You do need to link in the appropriate manifest file, such as the one in the `windows/` folder (I still need to figure out exactly what is needed apart from the Common Controls v6 dependency, or at least to create a complete-ish template), or at least include it alongside your executables. This also means you should no longer see random cmake errors when building the static libraries.
* **18 April 2018**
* Introduced a new `uiTimer()` function for running code on a timer on the main thread. (Thanks to @cody271.)
* Migrated all code in the `common/` directory to use `uipriv` prefixes for everything that isn't `static`. This is the first step toward fixing static library oddities within libui, allowing libui to truly be safely used as either a static library or a shared library.
* **18 March 2018**
* Introduced an all-new formatted text API that allows you to process formatted text in ways that the old API wouldn't allow. You can read on the whole API [here](https://github.com/andlabs/libui/blob/8944a3fc5528445b9027b1294b6c86bae03eeb89/ui_attrstr.h). There is also a new examples for it: `drawtext`, which shows the whole API at a glance. It doesn't yet support measuring or manipulating text, nor does it currently support functions that would be necessary for things like text editors; all of this will be added back later.
* libui also now uses my [utf library](https://github.com/andlabs/utf) for UTF-8 and UTF-16 processing, to allow consistent behavior across platforms. This usage is not completely propagated throughout libui, but the Windows port uses it in most places now, and eventually this will become what libui will use throughout.
* Also introduced a formal set of contribution guidelines, see `CONTRIBUTING.md` for details. They are still WIP.
* **17 February 2018** * **17 February 2018**
* The longstanding Enter+Escape crashes on Windows have finally been fixed (thanks to @lxn). * The longstanding Enter+Escape crashes on Windows have finally been fixed (thanks to @lxn).
* **Alpha 3.5 is now here.** This is a quickie release primiarly intended to deploy the above fix to package ui itself. **It is a partial binary release; sorry!** More new things will come in the next release, which will also introduce semver (so it will be called v0.4.0 instead). * **Alpha 3.5 is now here.** This is a quickie release primiarly intended to deploy the above fix to package ui itself. **It is a partial binary release; sorry!** More new things will come in the next release, which will also introduce semver (so it will be called v0.4.0 instead).

* Decided to split the table stuff into its own branch. It will be developed independently of everything else, along with a few other features.
* **2 November 2016**
* Added two new functions to replace the deleted `uiWindowPosition()` and friends: `uiAreaBeginUserWindowMove()` and `uiAreaBeginUserWindowResize()`. When used in a `uiAreaHandler.Mouse()` event handler, these let you initiate a user-driven mouse move or mouse resize of the window at any point in a uiArea.
* **31 October 2016**
* @krakjoe noticed that I accidentally used thread-unsafe code in uiQueueMain() on Unix. Fixed.
* **24 October 2016**
* `uiWindowSetContentSize()` on Unix no longer needs to call up the GTK+ main loop. As a result, bugs related to strange behavior using that function (and the now-deleted `uiWindowSetPosition()` and `uiWindowCenter()`) should go away. I'll need to go through the bugs to verify as much, though.
* **22 October 2016**
* Due to being unable to guarantee they will work (especially as we move toward capability-driven window systems like Wayland), or being unable to work without hacking that breaks other things, the following functions have been removed: `uiWindowPosition()`, `uiWindowSetPosition()`, `uiWindowCenter()`, and `uiWindowOnPositionChanged()`. Centering may come back at some point in the future, albeit in a possibly restricted form. A function to initiate a user move when a part of a uiArea is clicked will be provided soon.
* **21 October 2016**
* `uiDrawTextWeightUltraBold` is now spelled correctly. Thanks to @krakjoe.
* **18 June 2016**
* Help decide [the design of tables and trees in libui](https://github.com/andlabs/libui/issues/159); the implementation starts within the next few days, if not tomorrow!
* **17 June 2016**
* **CMake 3.1.0 is now required.** This is due to CMake's rapid development pace in the past few years adding things libui needs to build on as many systems as possible. If your OS is supported by libui but its repositories ship with an older version of CMake, you will need to find an updated one somewhere.

## Building ## Building
libui uses only [the standard Meson build options](https://mesonbuild.com/Builtin-options.html), so a libui build can be set up just like any other: Out-of-tree builds typical of cmake are preferred:
``` ```
$ # you must be in the top-level libui directory, otherwise this won't work $ # you must be in the top-level libui directory, otherwise this won't work
$ meson setup build [options] $ mkdir build
$ ninja -C build $ cd build
$ cmake ..
``` ```
Once this completes, everything will be under `build/meson-out/`. (Note that unlike the previous build processes, everything is built by default, including tests and examples.) Pass `-DBUILD_SHARED_LIBS=OFF` to `cmake` to build a static library. The standard cmake build configurations are provided; if none is specified, `Debug` is used.
The most important options are: If you use a makefile generator with cmake, then
* `--buildtype=(debug|release|...)` controls the type of build made; the default is `debug`. For a full list of valid values, consult [the Meson documentation](https://mesonbuild.com/Running-Meson.html). ```
* `--default-library=(shared|static)` controls whether libui is built as a shared library or a static library; the default is `shared`. You currently cannot specify `both`, as the build process changes depending on the target type (though I am willing to look into changing things if at all possible). $ make
* `-Db_sanitize=which` allows enabling the chosen [sanitizer](https://github.com/google/sanitizers) on a system that supports sanitizers. The list of supported values is in [the Meson documentation](https://mesonbuild.com/Builtin-options.html#base-options). $ make tester # for the test program
* `--backend=backend` allows using the specified `backend` for builds instead of `ninja` (the default). A list of supported values is in [the Meson documentation](https://mesonbuild.com/Builtin-options.html#universal-options). $ make examples # for examples
```
Most other built-in options will work, though keep in mind there are a handful of options that cannot be overridden because libui depends on them holding a specific value; if you do override these, though, libui will warn you when you run `meson`. and pass `VERBOSE=1` to see build commands. Build targets will be in the `build/out` folder.
The Meson website and documentation has more in-depth usage instructions. Project file generators should work, but are untested by me.
For the sake of completeness, I should note that the default value of `--layout` is `flat`, not the usual `mirror`. This is done both to make creating the release archives easier as well as to reduce the chance that shared library builds will fail to start on Windows because the DLL is in another directory. You can always specify this manually if you want. On Windows, I use the `Unix Makefiles` generator and GNU make (built using the `build_w32.bat` script included in the source and run in the Visual Studio command line). In this state, if MinGW-w64 (either 32-bit or 64-bit) is not in your `%PATH%`, cmake will use MSVC by default; otherwise, cmake will use with whatever MinGW-w64 is in your path. `set PATH=%PATH%;c:\msys2\mingw(32/64)\bin` should be enough to temporarily change to a MinGW-w64 build for the current command line session only if you installed MinGW-w64 through [MSYS2](https://msys2.github.io/); no need to change global environment variables constantly.
Backends other than `ninja` should work, but are untested by me.
## Installation ## Installation
Meson also supports installing from source; if you use Ninja, just do
```
$ ninja -C build install
```
When running `meson`, the `--prefix` option will set the installation prefix. [The Meson documentation](https://mesonbuild.com/Builtin-options.html#universal-options) has more information, and even lists more fine-grained options that you can use to control the installation.

[00:10:08] <hergertme> andlabs: is there API yet to load from memory? last i checked i only found from file (which we use in builder). https://git.gnome.org/browse/gnome-builder/tree/libide/editor/ide-editor-map-bin.c#n115

[00:15:19] <andlabs> hergertme: no, which is why I was asking =P
[00:15:30] <andlabs> I would have dug down if I could ensure at least something about the backends a GTK+ 3 program uses
[00:15:39] <andlabs> on all platforms except windows and os x
[00:16:11] <hergertme> to the best of my (partially outdated, given pace of foss) knowledge there isn't an api to load from memory
[00:16:28] <hergertme> you can possibly make a tmpdir and put a temp file in there
[00:16:52] <hergertme> and load that as your font dir in your FcConfig, so any PangoFontDescription would point to that one font, no matter what
[00:17:18] <hergertme> (using the API layed out in that link)

[00:40:38] <andlabs> hergertme: not necessarily fontconfig
[00:40:45] <andlabs> it can be with ft2 or xft I guess
[00:40:55] <andlabs> especially since I want the API NOT to make the font part of the font panel
[00:42:07] <hergertme> what sort of deprecated code are you trying to support?
[00:42:35] <hergertme> both of those are deprecated in pango fwiw
[00:43:06] <hergertme> on Linux im pretty sure we use FC everywhere these days
[00:44:46] <hergertme> (and gtk_widget_set_font_map() is how you get your custom font into a widget without affecting the global font lists, as layed out in that link)

[01:07:54] <andlabs> all right, thanks
[01:08:05] <andlabs> hergertme: fwiw right now my requirement is 3.10
[01:10:47] <hergertme> ah, well you'll probably be missing the neccesary font API on gtk_widget
[01:11:04] <hergertme> but pango should be fine even back as far as https://developer.gnome.org/pango/1.28/PangoFcFontMap.html
[01:11:56] <andlabs> good
[01:12:04] <andlabs> because this is for custom drawing into a DrawingArea
[01:14:12] <hergertme> presumably just create your PangoContext as normal, but call pango_context_set_font_map() with the map you've setup. now, the load a font from a file i dont think was added to FontConfig until later though (not sure what release)
[01:15:53] <hergertme> FcConfigAppFontAddFile() <-- that API
[01:16:30] <hergertme> great, and they don't say what version the API was added in teh docs

In general, all names that begin with "ui" and are followed by a capital letter and all names htat begin with "uipriv" and are followed by a capita lletter are reserved by libui. This applies even in C++, where name mangling may affect the actual names in the object file.
# Reserved names; for users
All reserved names in libui are defined by a prefix followed by any uppercase letter in ASCII. The bullet lists before list those prefixes.
Global-scope identifiers of any form (variables, constant names, functions, structure names, union names, C++ class names, enum type names, enum value names, C++ namespace names, GObject class and interface struct names, and Objective-C class and protocol name identifiers) and macro names:
- `ui`
- `uipriv`
GObject and Objective-C class, interface, and protocol name strings, in the form they take in their respective runtime memory (e.g. when passed to `g_type_from_name()` and `NSClassFromString()`, respectively):
- `uipriv`
Objective-C method names:
- `initWithUipriv`
- `initWithFrame:uipriv` (TODO probably worth removing)
- `uipriv`
- `isUipriv` (for compatibility with KVO and `@property` statements)
- `setUipriv` (for compatibility with KVO and `@property` statements)

Proper vertical text support in uiDrawTextLayout was removed because DirectWrite doesn't add this until Windows 8.1 (unless I drop IDWriteTextLayout and do the script analysis myself; TODO consider this possibility).
On OS X, setting the vertical forms attribute stacks non-vertical scripts in vertical text (rotates each individual glyph) with Core Text, whereas everything else — including Cocoa's text system — rotates entire non-vertical strings. Not sure what to do about this except manually detect which characters to apply the attribute to:
http://www.unicode.org/notes/tn22/RobustVerticalLayout.pdf
http://www.unicode.org/Public/vertical/revision-17/VerticalOrientation-17.txt
In addition, with Core Text, the vertical forms attribute vertically centers the vertical glyphs on the bhorizontal baseline, rather than flush with the text. Using the baseline class attribute doesn't seem to work.
TODO investigate kCJKVerticalRomanPlacementType
If readded, this will need to be a layout-wide setting, not a per-character setting. Pango works right this way; the current Pango code doesn't seem to work.

https://www.w3.org/TR/REC-CSS2/notes.html
TODO indicate where in the attributes.c file that block of code should go (or drop it entirely for the reasons listed above)
TODO same for ui.h

Hi. I recommend you today to start with OS/2 Warp 4.52 or ArcaOS ( The tools are almost the same of Warp 3). EDM/2 is a good place to start: http://www.edm2.com
https://twitter.com/OS2World/status/983822594465034240
There is also an RPM with OS/2 Software (https://www.arcanoae.com/resources/downloadables/arca-noae-package-manager/ …), and you can get from it some parts of the OS/2 Toolkit. If you want to develop drivers you require the OS/2 Device Driver Kit. (that is more complex). You can also develop in Qt4 and compile things with gcc.

// - CTFontCreateCopyWithAttributes()
