I have asked the question before, but freedom or not, the above is a nuisance to run for every language. If the process is as automatic as the above example demonstrates, shouldn't Emacs have a command to take a grammar and compile+install it? I guess this could be more complicated if the grammar is generated using a custom tool-chain for each language (or is it always Javascript?), but nothing impossible. What would be even better is if the grammars were to be distributed along with Emacs (either in a tarball or as a dependency a package manage would install).
