After final improvements to the official formatter implementation, this commit now performs the first treewide reformat of Nix files using it. This is part of the implementation of RFC 166. Only "inactive" files are reformatted, meaning only files that aren't being touched by any PR with activity in the past 2 months. This is to avoid conflicts for PRs that might soon be merged. Later we can do a full treewide reformat to get the rest, which should not cause as many conflicts. A CI check has already been running for some time to ensure that new and already-formatted files are formatted, so the files being reformatted here should also stay formatted. This commit was automatically created and can be verified using nix-builda08b3a4d19

longDescription = ''
|
|
LambdaLisp is a Lisp interpreter written as a closed untyped lambda calculus term.
|
|
It is written as a lambda calculus term LambdaLisp = λx. ... which takes a string
|
|
x as an input and returns a string as an output. The input x is the Lisp program
|
|
and the user's standard input, and the output is the standard output. Characters
|
|
are encoded into lambda term representations of natural numbers using the Church
|
|
encoding, and strings are encoded as a list of characters with lists expressed as
|
|
lambdas in the Mogensen-Scott encoding, so the entire computation process solely
|
|
consists of the beta-reduction of lambda terms, without introducing any
|
|
non-lambda-type object.
