comments.lua

Place the scripts into a folder called "common" in your modules directory. For example: "~/.textadept/modules/common/comments.lua".

Call these functions from the "commands.lua" file for your language. Example:

['\n'] = function()
    buffer:new_line()
    buffer:begin_undo_action()
    local cont = continue_block_comment("/*", "*", "*/", "/%*", "%*", "%*/")
    if cont then
        continue_line_comment("//", "//")
    end
    buffer:end_undo_action()
end,

This will auto-continue comments for languages like C++, and Java. This example happens to be for C++. The syntax for calling these functions is explained in the documentation comments of the script. Remember that the * and + characters must be escaped with the % character when they are used in patterns.
