1.4.0 Beta 1 (26.1-26.2)

1.4.0 Beta 1

Changes:

• Increased the Mappings format version to 4, which:
  • Does not break compatibility this time, because fv 2 and 3 mappings still load.
  • Added more vanilla override actions for editing: OVR_CUT, OVR_COPY, OVR_PASTE, and OVR_SELECT_ALL.
  • Added support for strict mode (enabled when the optional strict boolean at the top level of the JSON is set to true) which throws exceptions to stop loading instead of logging warnings when the following recoverable errors occur:
    • There is a duplicate action registration (including conflicts between different actions)
    • An unknown friendly keyname is specified
    • An unknown action name is specified
    • Action or system names have leading/trailing whitespace or have the wrong capitalization.
    • Numbers that don't adhere to the RegEx -?(0|[1-9]\d*) but would pass Integer.parseInt() and therefore would be accepted not in strict mode.
  • It is now a requirement that all builtin mappings load successfully in strict mode.
• Added a sharecode system for generating long encoded strings of mappings files that are easier to work with than raw JSON and the mod can automatically import for you.
• Added the following new builtin mappings sets: builtin:emacs_windows_linux, builtin:emacs_mac, and builtin:readline.
• Internal code improvements.
