sep

let sep = del /([ \t]+)|([ \t]*=[ \t]*)/ " = "

Key and values are separated by either spaces or an equal sign

Augeas Variables

word_opt_quot_re

let word_opt_quot_re = /[A-Za-z][A-Za-z0-9_]*/

Strings that don’t require quotes

Augeas Lenses

word_opt_quot

let word_opt_quot = Quote.do_squote_opt (store word_opt_quot_re)

Storing a word_opt_quot_re, with or without quotes

Augeas Variables

number_re

let number_re = Rx.reldecimal . /[kMG]?B|[m]?s|min|h|d/?

A relative decimal number, optionally with unit

Augeas Lenses

number

let number = Quote.do_squote_opt (store number_re)

Storing number_re, with or without quotes

word_quot

let word_quot = let esc_squot = /\\\\'/ in let no_quot = /[^#'\n]/ in let forbidden = word_opt_quot_re | number_re in let value = (no_quot|esc_squot)* - forbidden in Quote.do_squote (store value)

Anything other than word_opt_quot or number Quotes are mandatory

entry_gen

let entry_gen (lns:lens) = Util.indent . Build.key_value_line_comment Rx.word sep lns Util.comment_eol
