A block enclosed in brackets
let body (attr:lens) = Build.block_newlines_spc (indent . attr . Util.eol) Util.comment
We would really like to say “the body can contain any of a list of a list of attributes, each of them at most once”; but that would require that we build a lens that matches the permutation of all attributes; with around 40 individual attributes, that’s not computationally feasible, even if we didn’t have to worry about how to write that down.
let bool (kw:regexp) = Build.key_value_line kw Sep.space sto_bool
A boolean switch
let bool = [ key "PRUNE_BIND_MOUNTS" . Sep.space_equal . Quote.do_dquote (store /[01]|no|yes/) . Util.doseol ]

A boolean switch with extended values
let boolean = store /true|false/
Store a boolean value
let boot = let image = [ label "image" . store fspath ] in let arg = [ label "arg" . store word ] in Build.key_value_line "boot" space (image . space . arg)
boot [image [-acds]] XXX: the last arguments are not always needed, so make them optional

let brackets (l:lens) (r:lens) (lns:lens) = l . lns . r
Put a lens inside brackets
let brackets = [ Build.brackets Sep.lbracket Sep.rbracket (key Rx.word) ]

Generic functions to build lenses
let by = [ key "by" . Sep.space . ( store ("anybody"|"unsigned") | by_key | by_group ) ]
by statements define who is allowed to upload.
let by_group = value "group" . [ key "group" . Sep.space . store Rx.word ]
Authenticate packages by a groupname.
let by_key = let any_key = [ store "any" . Sep.space . key "key" ] in let named_key = [ key "key" . Sep.space . store (Rx.word - "any") ] in value "key" . (any_key | named_key)
When a key is used to authenticate packages, the value can either be a key ID or “any”:
let byte = /25[0-5]?|2[0-4][0-9]|1[0-9]{2}|[1-9]?[0-9]/
