Add list of linters / editor plugins implementing the styleguide to the readme

[ckrack]

Hi,
I'm creating this issue as a follow-up to a question on twitter.
The idea is to be able to follow this issue to be notified, when there are plugins/linters available.

Ideas for implementation:

• Eslint plugin like gajus/eslint-plugin-sql
• php-cs-fixer plugin
• standalone linter like sqllint

I would also like to know if someone has tried to build an auto-formatter/prettifier based on this style guide?

[treffynnon]

I would prefer to go with a standalone option that could be integrated by others into tool specific wrappers like plugins for eslint, etc. This way it can be used by more people across varied build architectures.

This is the closest I have seen so far. It is from the CockroachDB labs by @mjibson - an example of the SQL output compared to a query specified in the style guide: example on sqlfum.pt

It also comes as a standalone go binary as well; that can be configured to format SQL on save in an editor etc.

There was some limited discussion on making it compatible with the sqlstyle.guide on Twitter: https://twitter.com/mjibson/status/1118234708117266433 but this doesn't appear to have been completed.

The code is available over at https://github.com/mjibson/sqlfmt

I will pay a bounty to whoever implements a command line standalone formatter/linter that adheres to this guide.

I have not looked closely yet, but perhaps SQLFluff might work too.

[powerman]

It would be nice to have SQLFluff config as close as possible to the guide.

No, SQLFluff is unable to do the most important part of this style, but there is open feature request/discussion for it: sqlfluff/sqlfluff#5379

🎉 I've found really good enough solution. It's a Prettier community plugin prettier-plugin-sql.

Here is my ~/.prettierrc.yml:

plugins:
  - prettier-plugin-sql
overrides:
  - files:
      - '*.sql'
    options:
      # Values: sql bigquery db2 db2i hive mariadb mysql n1ql postgresql plsql redshift
      # singlestoredb snowflake spark sqlite transactsql tsql trino
      language: postgresql
      # Values: preserve upper lower
      keywordCase: upper
      dataTypeCase: upper
      functionCase: upper
      identifierCase: preserve
      # Values: standard tabularLeft tabularRight
      indentStyle: tabularRight
      expressionWidth: 96

and here is result of processing all SQL mentioned in https://www.sqlstyle.guide/ in a single file:

     FROM file_system
    WHERE file_name = '.vimrc';

/* Updating the file record after writing to the file */
