'io.popen' not implemented in MUSHclient

It works on command line.

Thanks.

Code:
function callRemoteLua(keyword)
print(keyword)
local handler = io.popen("lua fengxianpoem.lua "..keyword)
local poem = handler:read("*all")
handler:close()
print("found answer:"..poem)
end

Try this instead:



But wait!
Are you calling another Lua from inside Lua? Why on earth would you do that?
Why not just import fengxianpoem.lua and call its functions?

Why I call another Lua script is because that I found that some dll only can be loaded in command line or console way.

So I can work around it by calling another Lua script which can call require("luaiconv") successfully.

I can get the output of another Lua which does many works for my logic and I just copy the result with simple function.

That's my purpose to call another Lua.

Thanks for your reply and I will try it later and back to you.

I have tried but output nothing to the temp file.
Its size is zero.
But when I run the code in command line,it output correct result.
Maybe it is because of asynchronize http request.
I don't know the root cause.

I've been trying to call luaiconv myself. Without success. Which characters sets are you translating from/to?

If you can require luaiconv from the command line you should be able to do it from your MUSHclient script. Maybe it isn't in your path or something like that.

I want to translate text between gbk and utf8 .
The text from mud is encoded in GBK but I handle It in lua in utf8
It works in Windows command line
I have installed lua5.1 by full package with an installer

I have put dlls into the same directory which lua script file stayed.
they are all in mushclient/scripts

I tried to load luaiconv with require "luaiconv" in mushclient lua script.

but it cannot find luaiconv. luaiconv placed in mushclient/scripts
and another copy in mushclient root directory also.
It doesn't work


so I want to call another lua which running in command line.

I have worked around this issue.

There are 2 luas to complete the mission:

1.demo.lua
First,call fengxianpoem to fetech some html page and parse it by keyword. and write the result into a local text file.

Second,read the text file for result.

Full path of file or lua is required for mushclient,otherwise it failed.

function getScriptFilePath(fileName)
local mushSupport = true
if mushSupport then
return GetInfo(66).."scripts\\"..fileName
else
return fileName
end
end

function callRemoteFengxianLua(keyword)
keyword = string.gsub(keyword,"。","")
keyword = string.gsub(keyword,"，",",")
print(keyword)
--Use fullpath
local script = getScriptFilePath("fengxianpoem.lua")
local resultPath = getScriptFilePath("fengxianpoemresult.txt")
local luacmd = "C:\\Program\ Files\\Lua\\5.1\\lua"
--lua shell command
local err = os.execute("\""..luacmd.."\" "..script.." "..keyword.." "..resultPath)
print("os.execute result:"..err)
--read result
local fileHandle = assert(io.open(resultPath,"r"),"failed to open file")
if fileHandle then
local dataUTF8 = fileHandle:read("*a");
print(dataUTF8)
end
fileHandle:close()

end

2.Fengxianpoem.lua
Fetech some data and parse it by keyword,save the result into a text file.

local keyword = "You failed when you get these words"
local filePath --full file path for writing result
if #arg>1 then
filePath = arg[2]
keyword = arg[1]
--print("keyword:"..keyword)
--print("filePath:"..filePath)

-- answerPoem5 fetech http page and parse it to result text,and write it to file.
----***luaiconv**** is called in this function.This is what I want.
---The lua script is running in command line so it works like that in command line.
local result = answerPoem5(keyword)
if not result then
result = ""
end
local fileHandle = assert(io.open(filePath,"w+"),"failed to open file")
--delay()
if fileHandle then
print("result:"..result)
fileHandle:write(result)
--delay()
fileHandle:close()
end
end


Thanks for your support.

I don't get require "luaiconv.dll" work yet.
And have no idea now.
