The Formatter Should Allow for Backticks within Quotes and Vice Versa

Understanding the Issue

When working with Caddy, a popular open-source web server, users often encounter issues with formatting their configuration files. One such issue was reported by a user who experienced problems with the caddy fmt command in version 2.10.0. The issue was triggered by the presence of backticks within quotes in the Caddyfile, which is a configuration file used by Caddy.

Background Information

The user in question had a pixel art in their Caddyfile in a respond directive in v2.9.1. When they updated to v2.10.0, they encountered an issue with caddy fmt that seemed to be caused by the patch mentioned in the issue report. The user provided a minimal reproduction of the issue, which involved creating a Caddyfile with a respond directive containing a single backtick.

Minimal Reproduction of the Issue

The user provided two examples of Caddyfile configurations:

  • v2.9.1:

:8080 { respond "`" }

    Running `caddy run` would result in an HTTP server being started, and a single backtick would be returned when running `curl 127.0.0.1:8080`.
*   **v2.10.0**:
    ```caddyfile
:8080 {
    respond "`"}

Running `caddy run` would fail with an error message indicating that there was an unexpected '}' because no matching opening brace, at Caddyfile:2.

Analysis of the Issue

The issue seems to be triggered by an uneven number of backticks. In the v2.10.0 example, the backtick is not properly closed, which causes the error. This suggests that the caddy fmt command is not correctly handling backticks within quotes.

Conclusion

The issue reported by the user highlights the need for the caddy fmt command to allow for backticks within quotes and vice versa. This would ensure that Caddy configuration files are formatted correctly, even when they contain complex syntax. The user's minimal reproduction of the issue provides a clear example of the problem and demonstrates the importance of proper formatting in Caddy configuration files.

Recommendations

To resolve this issue, the caddy fmt command should be modified to correctly handle backticks within quotes. This could involve adding additional logic to the command to detect and handle uneven numbers of backticks. Additionally, the Caddy documentation should be updated to provide guidance on how to properly format Caddy configuration files, including examples of how to use backticks within quotes.
