My regex skills are probably less than par but I'm having some trouble getting this comment var to work with shellvars.aug.
error in augtool:
/augeas/files/etc/sysconfig/nfs/error = "parse_failed"
/augeas/files/etc/sysconfig/nfs/error/pos = "0"
/augeas/files/etc/sysconfig/nfs/error/line = "1"
/augeas/files/etc/sysconfig/nfs/error/char = "0"
/augeas/files/etc/sysconfig/nfs/error/lens = "/usr/share/augeas/lenses/dist/shellvars.aug:47.12-.45:"
/augeas/files/etc/sysconfig/nfs/error/message = "Iterated lens matched less than it should"
current shellvars comment:
let key_re = /[A-Za-z0-9_]+(\[[0-9]+\])?/ - "unset" - "export"
let eq = Util.del_str "="
let empty = Util.empty
let comment =
let line_re = /(#[^ \t][^\n]*)?/ - (key_re . "=" . /.*/) in
[ label "#comment" . empty . store line_re . del /\n/ "\n" ]
David has been helping a lot with this and I know that line_re should match all '#.*' minus anything that looks like a setting though only limiting it to key_re . '=' . /.*/ is not the best way to handle this since other settings may be written as 'var:val'.
In any case I can't quite understand why I'm getting that particular error message.
