Hi all, I just released Mathex 0.2 (https://github.com/juliendelplanque/mathex/releases/tag/0.2). Here are the improvements: - Made preview in GT-Inspector asynchronous. - Improved LaTeX code generated for compilation. - Mathex Rewriter is now loadable using 'MLoader loadRewriter'. - Removed greek letters globals, replaced them by #symbol asMathex. - Added some tests. - Some more refactoring. Documentation on Mathex-Rewriter package will be available soon on the wiki. In a nutshell it allows to write 'Mathex smalltalk' ie using literals without having to send explicitly #asMathex messages on them. So: ($b asMathex negated pm: #Delta asMathex sqrt) // (2 asMathex ,, $a asMathex) can be wrote: ($b negated pm: #Delta sqrt) // (2 ,, $a) to generate: '\frac{- b \pm\sqrt{\Delta}}{ 2 a }' if you use Mathex-Rewriter. It comes with a GUI (see attachment) that allows to write both Smalltalk and "Mathex-Smalltalk". Regards, Julien
