/* Tool to sort attribute sets. Primarily useful for keeping
|
|
all-packages.nix tidy.
|
|
|
|
To compile:
|
|
|
|
$ strc -i ../../maintainers/scripts/sort-attrs.str -la stratego-lib
|
|
|
|
Typical invocation:
|
|
|
|
$ sglr -m -p ~/Dev/nix/src/libexpr/nix.tbl -i all-packages.nix \
|
|
| implode-asfix --lex \
|
|
| ../../maintainers/scripts/sort-attrs \
