Scite Word Select

Quick setup

First of all, put the following code into your Lua startup file:

function isWordChar(char)
    local strChar = string.char(char)
    local beginIndex = string.find(strChar, '%w')
    if beginIndex ~= nil then
        return true
    end
    if strChar == '_' then
        return true
    end
    return false
end

function SelectWord()
    local beginPos = editor.CurrentPos
    local endPos = beginPos
    while isWordChar(editor.CharAt[beginPos-1]) do
        beginPos = beginPos - 1
    end
    while isWordChar(editor.CharAt[endPos]) do
        endPos = endPos + 1
    end
    if beginPos ~= endPos then
        editor.SelectionStart = beginPos
        editor.SelectionEnd   = endPos
    end
end

After that, you need to bind a shortcut key for SelectWord. In your properties file place the following code, replacing 13 with an unused command number. Also, feel free to use whatever shortcut you like instead of Ctrl+J.

command.name.13.*=Select Word
command.mode.13.*=subsystem:lua,savebefore:no,groupundo
command.shortcut.13.*=Ctrl+J
command.13.*=SelectWord
