Gitignore syntax not fully supported

[ddnexus]

To ignore files that do not require validation you can use a .solhintignore file. It supports rules in the .gitignore format.

The pattern to ignore a dir excluding specific files in .gitignore does not seem to work:

*
!not-this-file.sol

@ddnexus
Solhint works like this.
Given this file structure:
(Brackets name represent folders just for better understanding)

[contracts]
contracts\ONE.sol
contracts\TWO.sol
[contracts\adapters]
contracts\adapters\THREE.sol
contracts\adapters\FOUR.sol
[contracts\adapters\uniswap]
contracts\adapters\uniswap\UNI.sol

If you want to run solhint on all files:
solhint contracts/*.* contracts/**/*.* contracts/**/**/*.*

If you want to run solhint on adapters folders and all of subfolders
solhint contracts/**/*.* contracts/**/**/*.*

If you want to exclude FOUR.sol and run in all other files:
Fill .solhintignore with this line
contracts/adapters/FOUR.sol
Then run
solhint contracts/*.* contracts/**/*.* contracts/**/**/*.*
FOUR.sol will be excluded

From your post I think you want to put a folder in the .solhintignore and with that notation you want to ignore the whole folder but not the file with the exclamation point, meaning:
If I put in .solhintignore this:
contracts/adapters/
!contracts/adapters/FOUR.sol

You want solhint to process only FOUR.sol from adapters folder...
Is that correct ?

[ddnexus]

Yes, that's how gitignore works!

Without it you would have to check the structure of contracts/adapters/ and update the many solhint arguments every time it changes.

thanks for the clarification
it is a good addition
we'll try to add that

BTW, the "file" could also be a pattern itself.
