A tiny, portable, immediate-mode UI library ported to Go (as of commit 0850aba860959c3e75fb3e97120ca92957f9d057, v2.02)

API changes

• Functions and structs are renamed to be PascalCase and the prefix mu_ is removed, like this:

  mu_push_command -> PushCommand

  mu_begin_treenode_ex -> BeginTreeNodeEx

  mu_get_clip_rect -> GetClipRect

• Every function that takes mu_Context (Context) instead has a Context reciever, so Button(ctx, label) becomes ctx.Button(label)

• Stacks are now slices with variable length, append is used for push and slice = slice[:len(slice)-1] is used for pop

• mu_Font (Font) is interface{}, since it doesn't store any font data. You can use reflect if you want to store values inside it

• All pointer-based commands (MU_COMMAND_JUMP) and the Command struct have been reworked to use indices

• The mu_Real type has been replaced with float32 because Go does not allow implicit casting of identical type aliases

• The library is split into separate files instead of one file

• The library is ~1300 lines of code in total

Additional functions:

• NewContext, which is a helper for creating a new Context
• ctx.Render, which calls a function for every command inside the command list, then clears it

Integrations, demos, renderers

• Ebitengine rendering backend + demo port: zeozeozeo/ebitengine-microui-go
• Official Ebitengine fork and integration efforts: ebitengine/microui

Notes

The library expects the user to provide input and handle the resultant drawing commands, it does not do any drawing/tessellation itself.
