 Posted: Wed Jul 19, 2017 9:50 pm Post subject: executing template |
 |
|
It seem the original thread have been deleted by OP, so here a quick dirty make of an executing template.
It use etlua
which allow insert lua output string into AA during Prologue stage (registerAutoAssemblerPrologue, before AOB).
It change the tostring inside the etlua.lua to give hex number for number type for AA script usage, it should won't affect other part of Lua in CE.
| Code: |
------------ setup start ---------
local ToString = tostring
local _disp = function(e)
local et = type(e)
if et=='number' then
return e<0 and string.format("-%X",-e) or string.format("%X",e)
else
return ToString(e)
end
end
tostring = _disp -- use our hex number tostring
local etlua = require'etlua'
tostring = ToString -- restore
etluaSeeSource = true
etluaIsDebug = true
-- set false if not need to debug,
-- etlua only give its own parsing error,
-- likely with WRONG source line number, if any.
-- etlua error likely cause AA error, and ...
-- AA error (even etlua have no error) likely give
-- WRONG source line number too
local function etluaParser(s,sc)
local trimL,trimR
if s.Count>0 then
trimL,trimR = s[0]:match"^%s*(////+)%s*[Ee][Tt][Ll][Uu][Aa]%s*%p*%s*(.-)$"
end
if trimL then
s.Delete(0)
s.Insert(0,table.concat{trimL,trimR})
local code = s.Text
local newcode,err = etlua.render(code,_G)
if newcode then
s.Text = newcode
if etluaSeeSource then print(newcode)end
elseif etluaIsDebug then
print"*** etlua parsing error:"
print(tostring(err))
end
end
end
if _regID then
unregisterAutoAssemblerPrologue(_regID)
end
_regID = registerAutoAssemblerPrologue(etluaParser)
------------ setup end ---------
-- no need to run setup another time
--- test -- the [ENABLE] part
local script = [[
////etlua <-- IMPORTANCE: 1st line must begin with [////etlua] to get preprocesser to work
<% --- begin multi-line lua
-- we need address1 defined before other etlua parsing
-- this autoAssemble not use etlua because not begin with /////etlua
autoAssemble[=[
unregistersymbol(address1)
label(address1)
registersymbol(address1)
$process:
address1:
]=]
%> ///<--- end lua
unregistersymbol(address2)
label(address2)
registersymbol(address2)
<% local choose = 2 -- lua chunks... %>
<% if (choose == 1) then %>
address1+10:
address2:
<% elseif (choose==2) then%>
address1+20:
address2:
<% elseif (choose==3) then%>
address1+30:
address2:
<% elseif (choose==4) then%>
address1+40:
address2:
<% end %>
]]
print(tostring(autoAssemble(script)))

How to setup:
== local use:
1 copy and paste [setup start ~ setup end] into a lua file
2 save this file in your CE/autorun directory
3 download etlua.lua, save it in your CE directory (not autorun)
== embed in *.CT
1 same as 1, but give it a name, eg. etlua_aa.lua
2 download etlua.lua, save somewhere
3 in your *.CT load etlua_aa.lua and etlua.lua as table file, menu:table>add file, (!check if CE change the file name)
4 replace original lua 'require' with:
| Code: |
OriginalRequire = OriginalRequire or _G.require
function require (modulename)
local m, pkl = modulename, package.loaded
if pkl[m] then return pkl[m] end
local tf = findTableFile(m) or findTableFile(m..'.lua')
if tf then
local ss = createStringStream()
local ms = tf.Stream
ss.Position,ms.Position=0,0
ss.CopyFrom(ms,ms.Size)
local src = ss.DataString
ss.Destroy()
local ok,ret = pcall(load,src,'-',nil,_ENV or _G)
if ok then ok,ret = pcall(ret,m,[[_:\]]..m..'.lua')end
if ok then
pkl[m] = ret or true
return pkl[m]
end
end
return OriginalRequire(modulename)
end
|
then somewhere (lua script in MR for CT, or in lua engine in cetrainer)
require"etlua_aa" -- no ext ".lua"
eg. in an initializing MR :
| Code: |
{$lua}
if syntaxcheck then return end
[ENABLE]
OriginalRequire = OriginalRequire or G.require -- paste modified require definition here
function require (modulename)
...
end
require"etlua_aa" -- load the executing templae, it should auto load the etlua.lua
etluaSeeSource = false
etluaIsDebug = false -- turn off debug
[DISABLE]
_G.require = OriginalRequire -- restore original require
-- could be just after previous require if no other module need to load.
|
check the filename in loaded table file, they have to be exact match, since table file name matching is case-sensitive.
--ADDED:
this two global in the script
etluaSeeSource = true
etluaIsDebug = true
is for limited debug.
set them true or false as need, add example in previous script
--ADDED:
Advice not execute timely action ,eg aobscan within etlua's lua execution since it must parse the script during syntaxcheck which may not have expected result worth the time waiting.
bye~
