What gui library is used by sublime text editor?

Question

I've downloaded an editor of sublimetext and I want to know what GUI library is used in there.

The filenames of files that are in the editor executables directory are:

bz2.pyd Microsoft.VC90.CRT.manifest    msvcp90.dll msvcr90.dll                    PackageSetup.py PackageSetup.pyc               pyexpat.pyd                    python26.dll python26.zip                   select.pyd sublimeplugin.py               sublimeplugin.pyc sublimetext.exe                unicodedata.pyd unins000.dat                   unins000.exe _ctypes.pyd                    _elementtree.pyd _hashlib.pyd                   _socket.pyd _ssl.pyd      

Can I find the information from the file names?

Answer 1

Sublime Text 2 is mostly coded in C++ and uses a custom UI toolkit. Here is the author, Jon Skinner, explaining it: http://news.ycombinator.com/item?id=2822114.

I keep meaning to write a blog post with some details on this, but as with many things, I usually end up coding instead. Sublime Text 2 is almost entirely C++ (with a smattering of Objective C for Cocoa and Python for plugins). Coding is generally fairly straight forward: code on one platform (mostly Linux at the moment, but I switch around frequently), and then make sure it still compiles elsewhere. Sublime Text 2 itself uses a custom UI toolkit. There are a lot of apps where this may not make sense, but it's not such an unreasonable choice for Sublime Text, where I always knew that a lot of the UI controls were going to have to be custom no matter the toolkit (e.g., the text control and tab controls). The UI toolkit sits on top of a cross platform abstraction layer, which is more a union of platform functionality rather than lowest common denominator.

Answer 2

a little Googling suggested it is using the Sublime GUI, which judging by the Debian source package is written in C++.

then again, running strings on the Linux sublime_text binary shows the following shared libraries (equivalent of Windows DLLs) which might suggest gtk:

/lib/ld-linux.so.2 libgtk-x11-2.0.so.0 libgdk-x11-2.0.so.0 libatk-1.0.so.0 libgio-2.0.so.0 libpangoft2-1.0.so.0 libpangocairo-1.0.so.0 libgdk_pixbuf-2.0.so.0 libcairo.so.2 libpng12.so.0 libpango-1.0.so.0 libfreetype.so.6 libfontconfig.so.1 libgobject-2.0.so.0 libgmodule-2.0.so.0 libgthread-2.0.so.0 librt.so.1 libglib-2.0.so.0 libpthread.so.0 libdl.so.2 libutil.so.1 libm.so.6 libX11.so.6 libstdc++.so.6 libgcc_s.so.1 libc.so.6 libgio-2.0.so libgio-2.0.so.0 module.so 

this also suggests gtk.
