# NimCocoa
|
|
|
|
NimCocoa is an experimental implementation of a ***Native*** GUI for the Nim programming language running on macOS.
|
|
|
|
Rather than rely on low level calls to objc_msgsend and it's variants, it uses actual Objective-C code modules I created that are wrapped using C-Style functions, which Nim can then use.
|
|
|
|
At the moment, the following GUI objects are available:
|
|
|
|
- NSWindow
|
|
|
|
- NSButton
|
|
|
|
- NSCombobox
|
|
|
|
- NSLabel
|
|
|
|
- NSMenu
|
|
|
|
- NSSavedialog
|
|
|
|
- NSTextfield
|
|
|
|
- NSCheckbox
|
|
|
|
- NSDialog
|
|
|
|
- NSLine
|
|
|
|
- NSMessagebox
|
|
|
|
- NSSlider
|
|
|
|
- NSListbox
|
|
|
|
- NSOpendialog
|
|
|
|
- NSTextedit
|
|
|
|
|
|
|
|
Here is an example of what coding with NimCocoa looks like:
|
|
|
|
```nim
|
|
import Cocoa / [NSWindow, NSTextfield, NSLabel, NSCheckbox, NSButton, NSLine, NSOpendialog, NSFunctions]
|
|
import json, os, plists, times
|
|
|
|
var mainWin: ID
|
|
|
|
var lblFile, txtFile, btnFile, lblAuthor, txtAuthor, lblApp,
|
|
txtApp, lblImage, txtImage, btnImage, line1, lblVersion,
|
|
txtVersion, lblIdent, txtIdent, line2, chkLaunch, btnExec: ID
|
|
|
|
const
|
|
width:cint = 800
|
|
height:cint = 310
|
|
winStyle = NSWindowStyleMaskTitled or NSWindowStyleMaskClosable or NSWindowStyleMaskMiniaturizable
|
|
|
|
|
|
proc main() =
|
|
|
|
Cocoa_Init()
|
|
|
|
mainWin = newWindow("macOS Application Bundler", width, height, winStyle)
|
|
|
|
lblFile = newLabel(mainWin, "Select Executable",30, 20, 120, 25)
|
|
txtFile = newTextField(mainWin, "", 160, 20, 500, 25)
|
|
btnFile = newButton(mainWin, "Load", 680, 20, 100, 25, getExecutable)
|
|
txtFile.anchor=akWidth; btnFile.anchor=akRight
|
|
|
|
lblAuthor = newLabel(mainWin, "Author Name", 30, 60, 120, 25)
|
|
txtAuthor = newTextField(mainWin, "", 160, 60, 500, 25)
|
|
txtAuthor.anchor=akWidth
|
|
|
|
lblApp = newLabel(mainWin, "Application Name", 30, 100, 120, 25)
|
|
txtApp = newTextField(mainWin, "", 160, 100, 170, 25)
|
|
txtApp.anchor=akWidth
|
|
|
|
lblImage = newLabel(mainWin, "Select Icon File", 30, 200, 120, 25)
|
|
txtImage = newTextField(mainWin, "", 160, 200, 500, 25)
|
|
btnImage = newButton(mainWin, "Load", 680, 200, 100, 25, getImage)
|
|
txtImage.anchor=akWidth; btnImage.anchor=akRight
|
|
|
|
line1 = newSeparator(mainWin, 30, 140, 750)
|
|
|
|
lblVersion = newLabel(mainWin, "Application Version", 350, 100, 130, 25)
|
|
txtVersion = newTextField(mainWin, "", 490, 100, 170, 25)
|
|
txtVersion.anchor=akRight; lblVersion.anchor=akRight
|
|
|
|
lblIdent = newLabel(mainWin, "Bundle Identifier", 30, 160, 120, 25)
|
|
txtIdent = newTextField(mainWin, "", 160, 160, 500, 25)
|
|
# btnCredits = newButton(mainWin, "Load", 680, 160, 100, 25, nil)
|
|
txtIdent.anchor=akWidth
|
|
|
|
line2 = newSeparator(mainWin, 20, 240, 750)
|
|
|
|
chkLaunch = newCheckBox(mainWin, "Launch Application?", 320, 270, 150, 25)
|
|
btnExec = newButton(mainWin, "Execute", 680, 270, 100, 25, createAppBundle)
|
|
chkLaunch.anchor=akLeft + akRight + akBottom; btnExec.anchor=akRight + akBottom
|
|
|
|
Cocoa_Run(mainWin)
|
|
|
|
if isMainModule:
|
|
main()
|
|
|
|
```
|
|
|
|
Which results in the following:

Same app resized, showing how objects flow based on their associated 'anchor' setting:

I am working on documenting the available objects/functions as well as examples.

Stay Tuned!
