Go bindings for Sciter

Attention

The ownership of project is transferred to this new organization. Thus the import path for golang should now be github.com/sciter-sdk/go-sciter, but the package name is still sciter.

Introduction

This package provides a Golang bindings of Sciter using cgo. Using go sciter you must have the platform specified sciter dynamic library downloaded from sciter-sdk, the library itself is rather small (under 5MB, less than 2MB when upxed) .

Most Sciter API are supported, including:

  • Html string/file loading
  • DOM manipulation/callback/event handling
  • DOM state/attribute handling
  • Custom resource loading
  • Sciter Behavior
  • Sciter Options
  • Sciter Value support
  • NativeFunctor (used in sciter scripting)

And the API are organized in more or less a gopher friendly way.

Things that are not supported:

  • Sciter Node API
  • TIScript Engine API

Getting Started

At the moment only Go 1.10 or higher is supported (issue #136).

  1. Download the sciter-sdk

  2. Extract the sciter runtime library from sciter-sdk to system PATH

    The runtime libraries lives in bin bin.lnx bin.osx with suffix like dll so or dylib

    • Windows: simply copying bin\64\sciter.dll to c:\windows\system32 is just enough
    • Linux:
      • cd sciter-sdk/bin.lnx/x64
      • export LIBRARY_PATH=$PWD
      • echo $PWD >> libsciter.conf
      • sudo cp libsciter.conf /etc/ld.so.conf.d/
      • sudo ldconfig
      • ldconfig -p | grep sciter should print libsciter-gtk.so location
    • OSX:
      • cd sciter-sdk/bin.osx/
      • export DYLD_LIBRARY_PATH=$PWD

  3. Set up GCC envrionmnet for CGO

    mingw64-gcc (5.2.0 and 7.2.0 are tested) is recommended for Windows users.

    Under Linux gcc(4.8 or above) and gtk+-3.0 are needed.

  4. go get -x github.com/sciter-sdk/go-sciter

  5. Run the example and enjoy :)

Sciter Desktop UI Examples

Sciter Version Support

Currently supports Sciter version 4.0.0.0 and higher.

About Sciter

Sciter is an Embeddable HTML/CSS/script engine for modern UI development, Web designers, and developers, can reuse their experience and expertise in creating modern looking desktop applications.

In my opinion, Sciter , though not open sourced, is an great desktop UI development envrionment using the full stack of web technologies, which is rather small (under 5MB) especially compared to CEF,Node Webkit and Atom Electron. :)

Finally, according to Andrew Fedoniouk the author and the Sciter END USER LICENSE AGREEMENT , the binary form of the Sciter dynamic libraries are totally free to use for commercial or non-commercial applications.

The Tailored Sciter C Headers

This binding ueses a tailored version of the sciter C Headers, which lives in directory: include. The included c headers are a modified version of the sciter-sdk standard headers.

It seems Sciter is developed using C++, and the included headers in the Sciter SDK are a mixture of C and C++, which is not quite suitable for an easy golang binding.

I'm not much fond of C++ since I started to use Golang, so I made this modification and hope Andrew Fedoniouk the author would provide pure C header files for Sciter. :)

    Async in tiscript doesn't work.

    My code is below

    async function someLongOp() {
  $(#btnGo).state.disabled = true;

  var result = await longOp();

  $(#btnGo).state.disabled = false;
} 

self.post(function() {
  $(#btnGo).on("click", function() {
    someLongOp();
  })
})

    It suppose to be a async call, but the main thread is blocked. Am I using await in the right way?

  • Sciter bindings maintenance discussion

    Sciter bindings maintenance discussion

    Hi there,

    According to your attention ad:

    This project is not maintained for a quite long time and is looking for a new project owner or some active contributors.

    May it would be better to create organization for Sciter bindings and transfer our repositories there?

    Also it would be easier to accept PRs, for example. I was going to update your Go bindings, but now I think that its even better to collect all repositories in single place.

    cc @c-smile @pravic @midiway @da-baranov @oskca

  • update to Sciter v4 needed or not ?

    update to Sciter v4 needed or not ?

    Hello all,

    just begin to read Sciter docs and looking here to use it with Go, but didn't tried anything yet. I saw that Sciter is now at v4.x, but it's indicate here a support of v3.3.03.

    is it a problem ? should I search to download an old Sciter version ? should I wait for an update of oskca/sciter ? is there an update planned..??

    thanks. ffred

  • SetText adds strange spacing before text

    SetText adds strange spacing before text

    Hi, I'm trying to get familiar with Sciter, so I tried to call some common DOM functions from Go using Go-sciter.

    Using SetText("") inside a "for" loop to change text periodically adds strange spaces before the text everytime the text gets updated.

    Notes: Using the inspector, I couldn't spot any space characters being added. Also, the inspector doesn't update with new text when SetText is used. The problem doesn't occur when SetHtml is used, and the updates are instantly reflected on the inspector. When display: inline-block is set on the element, the spacing disappears.

    UPDATE: using the inspector's this.text doesn't show the same behavior, it updates the text without the strange space

    The code below produces the described incidence.
