Wrap and indent text using coreutils

### Short version I would like to create a tabular display of multiline text, similar to the following: all Build all targets document Create documentation of source files in the subfolders src and script, and write it to man test Run unit tests At the moment, my input for this looks as follows, but this can of course be changed: all---Build all targets document---Create documentation of source files in the subfolders src and script, and write it to man test---Run unit tests I’ve tried achieving this with a combination of awk and wrap/pr but while the line wrapping works, the indentation doesn’t. Here’s my current approach: … | awk -F '---' "{ printf '%-10s %s\n', $1, $2 }" \ | fold -w $(($COLUMNS - 1)) -s It generates the output all Build all targets document Create documentation of source files in the subfolders src and script, and write it to man test Run unit tests … in other words, the third line isn’t indented as intended. **How can I format the text with a given wrap length and a given hanging indent width?** — Without changing anything else about the text. Bonus: this should work with UTF-8 and escape/control characters. --- ### Background info The goal is to create [self-documenting Makefiles](https://gist.github.com/klmr/575726c7e05d8780505a) . As a consequence, the logic to format and display the code should be small, self-contained, and not rely on separately installed software; ideally, it should work on any system that can execute Makefiles, hence my restriction to (something close to) coreutils. That said, I briefly tried solving the problem using groff but this became too complex very quickly (and OS X groff is and old version that doesn’t seem to support UTF-8). The *original string* that I’m trying to parse and format therefore looks rather as follows: ## Build all targets all: test document ## Run unit tests test: ./run-tests . ## create documentation of source files in the subfolders src and script, ## and write it to man document: ${MAKE} -C src document ${MAKE} -C script document At the moment, this is parsed using a sed script (see link for details) that ignores multiline comments, before being fed to the formatting code posted above.
