Hi,
suppose I have a lens:
module Minimal =
autoload xfm
let del_str = Util.del_str
let eol = Util.eol
let entry = [label "entry" . store /[0-9]+/] . eol
let begin = del_str "BEGIN" . eol
let contents = entry*
let end = del_str "END" . eol
let lns = begin . contents . end
let xfm = transform lns (incl "/tmp/minimal")
and file /tmp/minimal:
BEGIN
12
32
aa
45
END
This produces a not very informative error message:
augtool> print /augeas/files/tmp/minimal/error
/augeas/files/tmp/minimal/error = "parse_failed"
/augeas/files/tmp/minimal/error/pos = "0"
/augeas/files/tmp/minimal/error/line = "1"
/augeas/files/tmp/minimal/error/char = "0"
/augeas/files/tmp/minimal/error/lens =
"/usr/share/augeas/lenses/dist/minimal.aug:13.10-.32:"
/augeas/files/tmp/minimal/error/message = "Input string does not
match at all"
------------------------------------------------------------------------
Now if I omit the begin and end from both the lens the file so I end up
with a lens:
...
let lns = contents
...
and file:
12
32
aa
45
I get much better and more informative error message:
augtool> print /augeas/files/tmp/minimal/error
/augeas/files/tmp/minimal/error = "parse_failed"
/augeas/files/tmp/minimal/error/pos = "5"
/augeas/files/tmp/minimal/error/line = "2"
/augeas/files/tmp/minimal/error/char = "2"
/augeas/files/tmp/minimal/error/lens =
"/usr/share/augeas/lenses/dist/minimal.aug:10.15-.21:"
/augeas/files/tmp/minimal/error/lens/last_matched =
"/usr/share/augeas/lenses/dist/minimal.aug:7.12-.26:"
/augeas/files/tmp/minimal/error/message = "Iterated lens matched
less than it should"
Is there a way to get the information of the second error message
without manually omiting the encapsulation of the iterated lens?
Thanks,
Štěpán
