Quick setup
This script allows you to select the word under the cursor. This is similar to the Edit/Select Word command in many text editors. 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
Explanations
The algorithm is quite simple. We have two variables which will be the the start and the end positions of the word. Initially, they are equals and point to cursor's position. We move beginPos to the left (by decrementing it) and endPos to the right (by incrementing it) until we hit the word's boundaries. Then we set the editor's selection using these variables.
