Let Me Click And Send

A simple Minecraft client-side mod, that reverts the run_command click event restriction introduced in 1.19.1-rc1,
so non-command messages can be sent freely as a chat message via run_command click event again

If you want a solution without user awareness, here's a server-side only mod that does the same thing:
LetMeClickAndSendForServer

Example

Let's run the following command, and then click the shown text

# Minecraft [1.7, 1.21.5)
/tellraw @a {"text":"click me to send \"hi\"","clickEvent":{"action":"run_command","value":"hi"}}

In vanilla 1.19.1 ~ 1.21.4, after clicking, you are not able to say anything since hi is not a valid command (not starts with /)

With this mod, after clicking, you will automatically send a hi chat message to the server, which is the same behavior as the previous Minecraft versions

MC 1.21.5+

Since MC 1.21.5, the run_command behavior has changed a lot

First is the change in command syntax, which has little impact:

# Minecraft [1.21.5, ~)
/tellraw @a {"text":"click me to send \"hi\"","click_event":{"action":"run_command","command":"hi"}}

Next is the change in behavior, which has a greater impact:

• The command value is always valid, regardless of whether it starts with a / or not
• The client will strip the / prefix from the command value and send the remaining string as a command

It's no longer possible to correctly distinguish between "a run_command for sending chat message" and "a run_command for sending command"

As a workaround, LetMeClickAndSend for MC >= 1.21.5 will only allow certain commands to bypass the vanilla check and always be click-and-send-able.
By default, only command value starting with !!, which is a commonly-used command prefix
in MCDReforged plugin ecosystem, will be allowed

A config file located at ./config/letmeclickandsend/config.json is added for customizing the bypass behavior

{
    "sendChatPattern": "!!.*"
}

The sendChatPattern should be a valid regex pattern. All command values that fully match the pattern will be as chat messages

To test with the default configuration, you can use:

/tellraw @a {"text":"click me to send \"!!MCDR\"","click_event":{"action":"run_command","command":"!!MCDR"}}

Requirements

It's a client-side only mod. It requires 0 extra dependency

Requirements:

• Minecraft >= 1.19.1
