Perhaps unused "" should't be marked? That's the point of using "", after all.

Or rather, it's correct html, but contains (1) numbered lines (with no content other than the line number), and (2) a bunch of messages at the bottom. There's no actual highlighted source code...

Here's the complete output (copied from the browser window) of running luainspect on the "test.lua" file in the source directory, like:

lua5.1 ./luainspect -fhtml -lhtmllib -o /tmp/x.html test.lua

It would be great if the work being done for smart code-assist in the Koneki LDT project could be integrated with LuaInspect. These two tools complement each other very well. LDT uses type inference via MetaLua to provide context sensitive code completion in the editor obtained from LDoc style commented code. See here for the announcement of code-assist in LDT: http://lua-users.org/lists/lua-l/2012-02/msg00536.html.

The original author of MetaLua is involved in the LDT project and some of the work they've done in MetaLua for code-assist is on the MetaLua git hub (probably the luaeclipse branch): https://github.com/fab13n/metalua/branches

Do you have any plans on doing something like this?

Perhaps this is already possible, but I couldn't figure out how to do it--I'm writing code that uses love2d, and I know (for instance) that a love.graphics.line function exists which takes x1, y1, x2, y2. Is there a way for me to provide this data to luainspect so it doesn't flag my calls to this function as "unknown field"?

lua-inspect could be really useful for Lua coders. Would you like to publish lua-inspect to LuaDist?

This way, users can install it easily with luadist install lua-inspect.

Hi,
I tried run lua-inspect in Lua 5.2.0 (compiled with LUA_COMPAT_ALL) and had errors (getfenv,setfenv).

I made some changes, and it seems, that goes -> C:\JS_LUA\lua-5.2.0\Debug\lua52.exe test.lua successfully produces examples.html
I'm sure (Lua newbie), that my changes are not fully correct, if somebody know, how do things correctly, please report.

...\metalualib\metalua\base.lua (only 1 row chaged):

....
row 9:   metalua={} -- if not metalua then rawset(getfenv(), 'metalua', { }) end
....

...\luainspect (version dependant empty getfenv/setfenv function added):

  local bin = script:gsub('[/\\]?[^/\\]+$', '') -- remove file name

local bin = findbin()

Hi,

I've found possibly another lexer error on this simple code:

if (tmp > 1) then return end

It's the () making troubles.

-- ynezz

after install luaforwindows its changes package.path and it can't lookup for files in script current path, so i add the following line to function load_module_source in init.lua

package.path = package.path .. ';'..props['FileDir']..'\\?.lua'

as seen below:

  -- Loads source code of given module name.
  -- Returns code followed by path.
  -- CATEGORY: utility/package
  local function load_module_source(name)
    --
    package.path = package.path .. ';'..props['FileDir']..'\\?.lua'
    --
    for spec in package.path:gmatch'[^;]+' do
      local testpath = plain_gsub(spec, '%?', (name:gsub('%.', '/')))
    local src, err_ = readfile(testpath)
       if src then return src, testpath end
    end
    return nil
  end 

lua-inspect is not compatible with scite 3.2.1, minor tweaks are needed, see:
https://groups.google.com/forum/?fromgroups#!topic/scite-interest/8PdNdUtGfBo

For a valid lua code:
a=1.0
I get lexer error:
warning: metalua failed to compile code that compiles with loadstring. error in metalua?
lua-inspect/metalualib/gg.lua:56: lua-inspect/metalualib/lexer.lua:129: assertion failed! 6

I made a workaround, but not sure what is the real fix:
metalualib/lexer.lua:129 if tag=='Number' and not content then content=0 end

lua-inspect is really handy; I wish there was good sublime text integration.

I see a lot of these messages (from the html, they do also appear in vim and scite):

attributes: unknown field
value: error:./luainspectlib/luainspect/init.lua:337: attempt to index local 't' (a nil value)
used-line:33

The error line in init.lua is also seen as 364.

I've seen this on several source files of mine, if needed could extract a test case.

From html.lua:98

      if ast.id then
        class = class .. " id" .. ast.id
      elseif ast.id then
        class = class .. " id" .. ast.localdefinition.id
      end

Hello

lexer:extract_short_string does not handle situations where there are mixed ' and " in same line.

For example:
LuaCode = "returnTxt='Hello from Lua!' .. inTxt .. ' / ' .. jit.version"

The readme has "See LICENSE file." in the License section, but there is not LICENSE file and no licensing information I can find.

When using lua-inspect in SciTE, when encountering Unicode text encoded in utf8, the syntax highlighting following the text is offset to where it is supposed to be - screenshot demonstrating the problem.

Also, the output pane of SciTE shows the following error:

lua-inspect/luainspectlib/luainspect/scite.lua:885: bad argument #1 to 'char' (invalid value)

I am not sure what causes this, but when I type a simple assignment containing a boolean value, part of it is highlighted as unknown global, see screenshot

After typing other lines, the incorrect highlighting disappears, even after erasing them and leaving only the first line, it works correctly for a while. After few more edits (erasing everything, typing something again), the following error comes up:

lua-inspect/luainspectlib/luainspect/ast.lua:204: attempt to perform arithmetic on local 'src_lpos' (a nil value)
