Not all letters are valid.

mode

let mode = /(-|~?[0-7]{4})/

”-”, or 4 bytes.  Optionally starts with a “~”.

”-”, or one of the formats seen in the manpage: 10d, 5seconds, 1y5days. optionally starts with a “~’.

argument

let argument = /([^# \t\n][^#\n]+)?[^# \t\n]/

The last field.  It can contain spaces.

field

let field = /[^# \t\n]+/

Applies to the other fields: path, gid and uid fields

record

let record = [ seq "record" . sep_opt_spc . [ label "type" . store type ] . sep_spc . [ label "path" . store field ] . ( sep_spc . [ label "mode" . store mode ] . ( sep_spc . [ label "uid" . store field ] . ( sep_spc . [ label "gid" . store field ] . ( sep_spc . [ label "age" . store age ] . ( sep_spc . [ label "argument" . store argument ] )? )? )? )? )? . Util.comment_or_eol ]

A valid record, one line in the file.  Only the two first fields are mandatory.

THE TMPFILES LENSE

lns

let lns = ( empty | comment | record ) *

The tmpfiles lens.  Each line can be a comment, a record or empty.
