Escaping '/' in regex filter selector

[Omniflux]

I have not been able to figure out how to properly escape '/' in a regular expression for the regex filter selector.

Not sure if it is not currently possible or if it could just use an example in the documentation...

>>> doc = [{'type': 'studio/material/a'}, {'type': 'studio/material/b'}]

Without '/' (success)

>>> jsonpath.compile('$[?@type =~ /studio.*/]').findall(doc)
[{'type': 'studio/material/a'}, {'type': 'studio/material/b'}]

With '/' (error expected)

>>> jsonpath.compile('$[?@type =~ /studio/material/.*/]').findall(doc)
jsonpath.exceptions.JSONPathSyntaxError: expected TOKEN_COMMA, found 'TOKEN_NAME'
  -> '$[?@type =~ /studio/material/.*/]' 1:22
  |
1 | $[?@type =~ /studio/material/.*/]
  |                       ^^^^^^ expected TOKEN_COMMA, found 'TOKEN_NAME'

With '\/'

>>> jsonpath.compile('$[?@type =~ /studio\/material\/.*/]').findall(doc)
jsonpath.exceptions.JSONPathSyntaxError: unexpected token '\\'
  -> '$[?@type =~ /studio\\/material\\/.*/]' 1:29
  |
1 | $[?@type =~ /studio\/material\/.*/]
  |                              ^ unexpected token '\\'

With '\\/'

>>> jsonpath.compile('$[?@type =~ /studio\\/material\\/.*/]').findall(doc)
jsonpath.exceptions.JSONPathSyntaxError: unexpected token '\\'
  -> '$[?@type =~ /studio\\/material\\/.*/]' 1:29
  |
1 | $[?@type =~ /studio\/material\/.*/]
  |                              ^ unexpected token '\\'

With '\\\/'

>>> jsonpath.compile('$[?@type =~ /studio\\\/material\\\/.*/]').findall(doc)
jsonpath.exceptions.JSONPathSyntaxError: unexpected token '\\'
  -> '$[?@type =~ /studio\\\\/material\\\\/.*/]' 1:30
  |
1 | $[?@type =~ /studio\\/material\\/.*/]
  |                               ^ unexpected token '\\'

Hi @Omniflux,

This was a bug in the JSONPath parser. Should be fixed in version 2.0.2, now released.

import jsonpath

query = "$[?@type =~ /studio\\/material\\/.*/]"
query_raw = r"$[?@type =~ /studio\/material\/.*/]"

data = [
    {"type": "studio/material/a"},
    {"type": "studio/material/b"},
    {"type": "studio foo"},
]


print(jsonpath.findall(query, data))
print(jsonpath.findall(query_raw, data))

print(jsonpath.findall("$[?@type =~ /studio.*/]", data))

Output

[{'type': 'studio/material/a'}, {'type': 'studio/material/b'}]
[{'type': 'studio/material/a'}, {'type': 'studio/material/b'}]
[{'type': 'studio/material/a'}, {'type': 'studio/material/b'}, {'type': 'studio foo'}]
