Troubleshooting Sequence to find preposition at beginning of sentence

[jastram]

Howdy vale community,

I am trying to build a very simple rule: It should not allow a sentence to start with a preposition. For instance: "It must also display the date." is not allowed. Acceptable would be: "The application must also display the date."

Tag for preposition is PRP, I double checked that this is correct by running "vale tag".

I expected this rule to work, but it does not:

extends: sequence
message: "Sentence should not start with a preposition."
tokens:
  - pattern: '^'
  - pos: PRP

I was wondering whether I could simply apply both rules in one token, like this (does not work either):

extends: sequence
message: "Sentence should not start with a preposition."
tokens:
  - pattern: '^\w+'
    pos: PRP

What am I doing wrong?!? Using vale 2.18.0. Thanks in advance!

There are two problems:

• pos is not a supported key; you likely meant tag.
• ^ matches the start of a line, not a sentence.

With the latest release, you can now use something like this:

extends: sequence
message: "Sentence should not start with a preposition."
tokens:
  - pattern: '[A-Z][a-z]+'
    tag: PRP

Ah thanks! Now I feel stupid, I was accidentally using the syntax from #110 instead from the official documentation.
