Unity3d scrollview with line numbers and code completion

The asset consists of two visual parts. An editor window with line numbers and code completion, and a separate code completion information view with header, image and text (see attachement). The attached image is a schematic only, the final asset is ment to be more visually pleasing. 1. The following should be defined by variables in the script: 1.1 Idividually set for each, one setting for editor and one setting for informaiton view: i. Position of upper left corner (x,y), with regards to the parent. ii. Height and with of views iii. Font sizes (including individual fontsize for line numbers) iv. Background color 1.2 List of objects containing code completion key-word, string of information view text and file-path to the image 2. Code completion: 2.1 It should only match the key-word list (not variables from the editor or anything else) 2.2 Code completion should show when first matching caracter is found. 2.3 It should only show alternatives for the first matching caracters. 2.4 Code completion for a key-word should always show, even if the key-word is not the first word in the editor 2.5 Clicking on or pressing enter will autocomplete the text for the selected key-word 2.6 Moving arrows down or up will select approptiate key-word 3. Other requirements: 3.1 Should be coded in C#. 3.2 Possibility to get or set the text in the code editor ( can get/set a List<string> ) 3.3 Should be able to handle 100 million lines of code without lagging when scrolling 3.4 Should be usable/scrollable with both mouse and touch 4. Other: 4.1 If there are assets in the unity store that solve some of the tasks, they could be considered for purchase as part of the project. But the lisence should not require redistribution of code or prevent resale.
