Dhall: A Gateway Drug to Haskell
The documentation of lenses is geared towards people know what lenses are. Of course this single fragment of documentation doesn't make sense if you don't know what lenses are. If you want to understand what lenses are the package links to a helpful wiki and tutorial: https://github.com/ekmett/lens/wiki/Overview
All within reach within seconds of discovering the function.

Google ZX – A tool for writing better scripts
If I want to write better shell scripts I usually run shellcheck and adjust accordingly or if I need facilities not provided by the shell i switch to a full fledged programming language. Ans oh yes, `sh` is present almost on every BSD and Linux box for free so I consider it an important thing to at least be comfortable with.

How I use Nix in my Elm projects
When I run nix-shell at the root of the project it puts me in a Nix shell that contains, among other programs, caddy and shellcheck. Notice that in the shellHook I add the project's shell scripts to the PATH. So once I'm in the Nix shell I can, among other things:

Regex support to list modules in .cabal?
I have also seen some projects on github like ShellCheck which first make a library, expose all the modules and then simple add that do build-depends of the final executable. Is this the recommended approach than having just one executable and adding all the modules to other-modules:?

Shellcheck finds bugs in your shell scripts
The error checks can be pretty arcane:

Is there a syntax checker?
Similar to for instance shellcheck to check the syntax of shell scripts, is there an equivalent for the set of roff commands typically used in a (Linux) man page? I'm aware that e.g. pandoc permits the conversion of an other format (e.g., org) to both roff man and roff ms.

I forgot to mention "shellcheck" at https://www.shellcheck.net/ and the explanation of its error codes at https://www.shellcheck.net/wiki/
This is also referenced by Shotts, and has been discussed on Hacker News -- not to be missed.
