great. thanks. if customizable, i'd vote to default with an error. then, for what it's worth, my experience led me to write some code for a command line program (basically, an elisp script) to tangle files. if anyone is interested in playing/using it, that'd be great. the idea is to figure out what languages are needed by walking the source code blocks, keeping track of languages, then set `org-babel-load-languages` appropriately, and tangle the file. ---- https://sr.ht/~minshall/org-cli-tangle/ ---- cheers, Greg
