LUA interpreter : how to autostart a lua program

[free_electron]

anyone using eLUA on Cortex ?
i want to know how i can run a lua program automatically on startup. google is broken ...

basically : is there an autoexec.bat ?

The default for that is init.lua.  It runs automatically on start up.

so if i add an init.lua to the rom filesystem that one will run ?

i want to make a small self starting lua script that checks for the presence of a flash memory on spi or i2c. if the memory is found and it contains a specific signature it will create a new file in the write once filesystem and copy the data from the eeprom over. this then becomes a new lua program that is called and launched.

Think of it as a small LUA bootloader.
lua starts and then launches my loader. this loader checks for the existence of an eeprom. if it exists : read signature. then : check eif app.lua exists in internal worm. if it does : compare signatures. if they match  :run app.lua. if they dont match : cope eeprom contents in new app.lua and then launch app.lua

the idea is to have the control program for a sensor reside in the sensor. if i plug it into the system (lua based) this will detect the sensor and automatically install the driver for it.

I work with the open source Apache Mynewt OS that has a lua interpreter:
https://mynewt.apache.org/latest/os/modules/elua/elua/

There is a sample app on github (app called "latest") that currently initializes lua via shell (so you can manually run the lua script at the prompt).
https://github.com/apache/incubator-mynewt-core/blob/master/apps/luatest/src/main.c

The shell command calls the lua_main(argc, argv) as shown in
https://github.com/apache/incubator-mynewt-core/blob/master/libs/elua/elua_base/src/lmynewt.c

You could write an app that calls lua_main() to start automatically on some trigger or periodically.
