S7schema 0.2.0

• Validation now checks the data that R reads (#70, #67). Files are validated as yaml::read_yaml() reads them, S7schema objects as write_config() writes them and R reads them back, and list objects in validate_list() as they are. Previously the YAML was parsed again by a JavaScript parser, which could read values differently. This changes some validation results:
  • Unquoted y, n, yes, no, on, and off in lowercase, title case, or uppercase (e.g. Yes, YES) are logical values. This also applies to map keys: y: is read as the key "TRUE" and n: as "FALSE". Quote them to keep them as strings.
  • Unquoted dates such as 2025-08-06 and values such as 1e3, 0o17, and 0b101 are strings.
  • Merge keys (<<: *anchor) resolve as in R: a key from the merged mapping wins over the same key set next to <<.
  • One-item sequences such as [a] in files and S7schema objects are single values. Use oneOf in the schema for fields that can hold one or more values.
  • NA, NaN, and Inf are validated as null. Allow null in the schema for fields that may be missing.
  • Date values in list and S7schema objects are validated as strings.
  • Numbers in files and lists are validated exactly. Numbers in S7schema objects are validated as write_config() writes them, which rounds numbers that need 17 significant digits, such as 0.1 + 0.2.
  • The current value in error messages is the value as R reads it.
• to_yaml() and write_config():
  • Logical NA is written as .na, so R reads it back as NA. Previously it was written as NA, which R read back as the string "NA".
  • Date values are written as ISO 8601 strings (2025-08-06) instead of the number of days since 1970-01-01.
  • Numbers are written with a precision of 15 instead of 7, so numbers with up to 16 significant digits are read back as the same value.
• validate_yaml() and S7schema() no longer warn when a YAML file has no final newline.
• jsonlite is now a required dependency, and js-yaml is no longer bundled.
• Uses ‘QuickJSR’ instead of ‘V8’ to run ‘ajv’, so the ‘V8’ system library is no longer needed (#56). The bundled fast-uri is updated to 3.1.8, which has security fixes.
• An invalid JSON schema now gives a short error with the schema file and the reason, instead of a JavaScript stack trace.

S7schema 0.1.2

• Validation error messages now include the current value that failed validation (#63).
• Now possible to create a S7schema() object in memory using the new .data argument (#62).
• Rebundled inst/bundle.js with updated JavaScript dependencies: ajv 8.17.1 → 8.18.0, js-yaml 4.1.0 → 4.3.1, and fast-uri → 3.1.5.

S7schema 0.1.1

• Fixed write_config() to use NULL as the default for the output path instead of x@file, and renamed the file argument to path (#48).

S7schema 0.1.0

• Initial CRAN submission.
