Those links appear to be dead - no response from here so its not your Country restrictions.

The links were to php code that had to be hosted on a web server.  I do not know if the source for that code is available - I could not find it with google.

Possibly the whole dataghost disappeared... Maybe somebody (especially the creator) still owns the code.

AFAIK beside above sites there is no WYSiWYG grid editor... I was thinking about writing my own on-camera grid editor, which wouldn't be very hard with use of Lua (at least much more simple than text editor;), but have still not enough time... Currently you have to stay with grids already published on wikia or making them just by typing the code... Of course you could write your own editor, everybody would appreciate:D

Your English is good enough and your request is understood.  However,  there is currently nobody working on that project.

Hello,
The attached LUA file allows testing/viewing of the text based GRD files.
Not my work, see LUA files for details of originator.

Best,

Colin

This is interesting stuff, and I supose usefull on PC, but the 6th line of the script contains a comment:

Code: [Select]
script intended for use on a PC with standard Lua distribution

This script can not be used on-camera - it needs PC. Even if a program is written in Lua it doesn't mean it will run on camera. This script requires specific libraries, which are not accessible on cameras. And probably never will.

For on-camera viewer (and further editor) one need to use Lua drawings commands.

However nice finding ;)

Wasn't able to find them in the repository for my Linux PC either - have not tried Windows yet.

Actually,  there is a much easier way to get an "on-camera" viewer ....

Sure :D But I was thinking about development of on-camera editor, so the viewer would be first task.

Ok, I've started development of the on-camera editor. At the moment it works only as a grid viewer. Any feedback welcome.

Limitations:

- no string support (yet, not a big deal)
- fails with sports.grd from standard CHDK - this grid has a bug - 'X' instead of 'x'.

Don't need to copy the code, lua file in attachment ;)

Code: (lua) [Select]
--[[
@title Grid editor

@param s Browser in GRIDS? (1=Yes)
@default s 1
@values s 0 1

@param a nothing
@default a 0
--]]

require "drawings"

--defaults and so on
PATH="A"        --where to open file_browser()?


--some other globals
file=nil        --nobody knows why lower-case...
FILENAME=""
FILE_CONTENT={}
FILE_LINESN=0   --this should be removed, it's just stupid - we have table.getn()
TITLE=""


function load_file()
    if s==1 then
        PATH="A/CHDK/GRIDS"
    end
    file=file_browser(PATH)
    if file==nil then
        print("No file selected!")
        --restore()
    else
        --here we process the PATH to get the FILENAME
        --I don't remember how does it work, but it does
        for li=0,string.len(file) do
            char=string.sub(file,string.len(file)-li,string.len(file)-li)
            if char~="/" then
                FILENAME=char..FILENAME
            else break
            end
        end
       
       
        --lets try to load this file--
        file_h=io.open(file,"r")
        print("Loading, wait...")
        FILE_CONTENT={}
        line=1
        repeat
            FILE_CONTENT[line]=file_h:read("*line")
            FILE_LINESN=line-1
            line=line+1
            until FILE_CONTENT[line-1]==nil
        file_h:close()
        if FILE_CONTENT[1]==nil then FILE_CONTENT={""} end
        if FILE_LINESN==0 then FILE_LINESN=1 end
    end
end

function process_file()
    --here we'll change the file info into drawings
    --all comments are lost!!!
    --Step 1 - walk through the file
    line=1
    repeat
        print(FILE_CONTENT[line])
       
        --check whether this line means something
        char=string.sub(FILE_CONTENT[line],1,1)
        --print(char)
        if char=="@" then --woohoo! found a command!
            --now we need to see, what's that...
            --the interpreter is dirty and assumes that everywhere you have one space. To be fixed.

            --@title
            if string.sub(FILE_CONTENT[line],1,6)=="@title" then
                TITLE=string.sub(FILE_CONTENT[line],8,string.len(FILE_CONTENT[line]))
                type="title"

            --@rectf
            elseif string.sub(FILE_CONTENT[line],1,6)=="@rectf" then
