這個工具藉由靜態與動態分析執行，利用透過 MetaLua (純 Lua 部分) 轉換而來的 AST 來執行。
lua luainspectlib/luainspect/command.lua examples.lua > test-output/examples.html
* analysis:
* identifies global (red) and local variables (blue), including locals that are
function arguments (dark blue) and upvalues (light blue)
* identifies unused local variables: e.g. `do local x=1 end` (white-on-blue)
* identifies local variables masking other locals (same name): e.g. `local x=1; local x=2`
(strikethrough and squiggle line)
* identifies local variables that have non-constant binding (`local x = 1; x = 2`) (italic)
* identifies unknown global variables (white-on-red) and table fields (red), inferred by
static and dynamic evaluation.
* infers values of variables (e.g. `local sum = math.pi + 2` is 5.14.
and defined-ness of members of imported modules
(`local mt = require "math"; math.sqrtt(2) -- undefined`)
* infers signatures of functions (including local, global, and module functions)
* checks number of function arguments against signatures (SciTE only)
* cross-references variables (locals and module fields) with their definitions and uses
(pink highlight), identifies range of lines/scope where the local is defined
(currently SciTE only), and supports jump-to-definition and jump-to-uses (SciTE only)
* identifies all keywords in selected block (underline)
* evaluate special comments (prefixed by '!') to inject semantic information into analysis
(similar to luaanalyze / lint).
* refactoring:
* command to rename all occurrences of selected variable (SciTE only)
* browsing:
* inspect members of selected table.
* select statement or comment containing current cursor selection (SciTE only)
* display real-time annotations of all local variables, like an Excel/Mathcad worksheet
(experimental feature via ANNOTATE_ALL_LOCALS) (currently SciTE only)
* auto-complete typing support (SciTE only) (experimental)
* interfaces: SciTE plugin, VIM plugin, and HTML output.
未實作而（但很可能應該實作）的功能
local x = "foo"; math.sqrt(x).rockspec 檔案、README、COPYRIGHT、函式庫命名慣例等。math.sqrt(2) 的程式碼時，在輸入最後的 (2) 使其成為有效的語法之前，會發生錯誤顯示而欠缺語法重點顯示。math.sqrt(2) --> local math_sqrt = math.sqrt ..... math_sqrt(2)）和其他的功能
在 [github] 可取得最新版本。
注意：包含 SciteExtMan 的修正版本（SciteExtMan 較舊的 2006-11-10 版本無法完全執行）。
在 SciTE 版本 2.12（較舊版本可能無法執行）和 SciteExtMan（2010-07-20 起）上測試。來自完整 SciteExtMan 的 ctagsdx.lua 是選用的（允許「到標記點」指令在「到定義」之後返回先前的位置）。
這可以用在 lua 使用者 wiki 和 [snippets.luacode.org] 來顯示 Lua 程式碼。
