constructive bidirectional programming[a]: treesitter[0] used with emacs[1] neovim[2] python[2.2] programming language boomerang, "A bidirectional programming language for ad-hoc, textual data"[b]; more traditional use in neural networks[c] xsugar for dual syntax xml language[d] piet-q exotic language interpretation (vs. program/application)[e] and/or q-code usage/application[f][g] can have fun with coding in c in way that 2nd program can be extrapolated from gcc ast syntax tree[3] scratch[4] bit simpler, but gis-piet[5] bit bigger. Hitchhicker's guide to the galaxy keeps it pretty small/simple with '42'; which means really have to fully expand/uncompress/unwind everything to get anything done. --- [a] https://www.youtube.com/watch?v=jy-dpzi8neQ https://www.youtube.com/watch?v=jy-dpzi8neQ [0] https://tree-sitter.github.io/tree-sitter/ https://tree-sitter.github.io/tree-sitter/ [1] https://www.masteringemacs.org/article/how-to-get-started-tree-sitter https://www.masteringemacs.org/article/how-to-get-started-tr...
