example:
!(
local ids = {
"typewriter",
}
for _, v in ipairs(ids) do
local cname = v .. "_on_finish"
outputLua("Concord.component('" .. cname .. "', function(c, signal, delay, ...)\n")
outputLua("\t@@assert(type(signal) == 'string')\n")
outputLua("\t@@assert(type(delay) == 'delay')\n")
outputLua("\tc.signal = signal\n")
outputLua("\tc.delay = delay or 0\n")
outputLua("\tc.args = {...}\n")
outputLua("end)\n\n")
end
)
(removing the line with @@ works)
The desired generated code is:
Concord.component('typewriter_on_finish', function(c, signal, delay, ...)
@@assert(type(signal) == 'string')
@@assert(type(delay) == 'delay')
c.signal = signal
c.delay = delay or 0
c.args = {...}
end)
the @@assert
is a function defined in the handler.lua
:
function assert(cond, msg)
if _RELEASE then return "" end
msg = msg or string.format("%q", "Assertion failed: " .. cond)
return "if not (" .. cond .. ") then error(" .. msg ..") end"
end
the error is unexpected symbol near '@'
does this already have something like this? Ive checked the wiki and havent found anything for it.
lua preprocess-cl.lua --handler=myHandler.lua src/main.lua2p ../output/src/
I have a handler.lua with:
_C_HSPEED = toLua("hspeed")
Which i use like local component = $_C_HSPEED
.
However, I also need to have something with !
prefix like : local n = "!hspeed"
Ive tried:
--handler.lua
function n(component) return "!" .. component end
with @@n($_C_HSPEED)
but it complains about the !
token as it outputs !"hspeed"
literally.
And yes, "!" .. $_C_HSPEED
works as it generates "!" .. "hspeed"
in the output file but this would be the last resort if no other way is possible
Hello, I would like to implement a macro definition feature similar to C++. Here is an example code. Could you please guide me on how to achieve this?
#define GIsShipping
#if GIsShipping then
#define Log(...) Log(...)
#else
#define Log(...)
#endif
I'm wondering why there's nothing like
lua preprocess-cmd.lua input.lua output.lua -isdebug
It would be useful and more appropriate for usage to be able to pass meta information than to make a build system like the one in your löve's example (also check the comment I've made there)
I have looked at the examples and the lua file itself. I may have missed it.

Hi, I am wondering if the lib already allows returning error code when a file can't be parsed (instead of just showing an error message)
My use case is that for my bash script, I want to catch that error and not continue running my build script if an error occurred.
--color.lua
local function convert(r, g, b)
return r/255, g/255, b/255 --it seems that only the r/255 is returned
end
--main/lua
!(@insert "color.lua")
local test = { !(convert(255, 255, 255)) }
print(unpack(test)) --prints only 1
Hi, parsing something this results to malformed string
error
local error_msg = format("Data integrity is not valid.\n
Please do not modify the files: '%s' and '%s'.\n
Please delete the files in '%s' and restart the game",
save_filename, key_filename, love.filesystem.getSaveDirectory())
Here's the output:
==============================================
= LuaPreprocess v1.11.0, 2020-08-09 12:08:54 =
==============================================
Processing 'test.lua2p'...

Making the string one-liner doesn't result to the error.
Hi, still tinkering with this awesome lib when I've found out that
--src/main.lua2p
local test_module
!if _DEBUG then
test_module = require("src.test_module") --"src/test_module" does not work either
!end
--src/test_modules.lua2p
local test_module = {}
!if _DEBUG then
print(1)
!else
print(2)
!end
return test_module = {}
error is that src/test_module
could not be found.
Does this mean that I have change all required modules that use src/**
to use srcgen/**
?
Hi, im doing some separation for my different builds. I have handler_dev.lua
and handler_test.lua
that I use depending on what I want to build.
Content of handler_dev.lua
:
_RELEASE = false
_REPORTING = false
_NETWORK = false
_ASSERT = true
_LOG_SAVE = false
require("handler")
return {}
Content of handler_test.lua
:
_RELEASE = true
_REPORTING = false
_NETWORK = false
_ASSERT = false
_LOG_SAVE = false
require("handler")
return {}
Now, handler.lua
is a file that contains all other metadata I need that is common to both of them, like:
_PLATFORM = "desktop"
_GAME_TITLE = "project name"
_GAME_SIZE = { x = 1024, y = 640 }
_GAME_BASE_SIZE = { x = 128, y = 32 }
_IDENTITY = "projectname"
_LOVE_VERSION = "11.3"
_GAME_VERSION = { 0, 0, 1 }
But having the require
gives this error:
Error @ output//error_handler.lua:139: 'end' expected (to close 'if' at line 134) near 'if'
