Re: Finally! A small-footprint text editor written in Lua

[Ra Do]

Hello all.

Sorry to dig out this old thread, but I have a question regarding this lua editor (https://github.com/martinwguy/lua-ed) ...

Since I don't have a MMC card implemented on my STM32F4-Discovery board yet, I've decided to flash the five .lua files to the ROMFS folder in order to give the editor a try.

It failed right after require "ed" with 

> require "ed"

error loading module 'mainloop' from file '/rom/mainloop.lua':

        not enough memory

stack traceback:

        [C]: ?

        [C]: in function 'require'

        /rom/ed.lua:3: in main chunk

        [C]: in function 'require'

        stdin:1: in main chunk

        [C]: ?

Do you think this is because it's running off the romfs, or because I am actually out of memory on the board ? 

Or perhaps I am out of memory because I've flashed these files to the rom, hence taking too much available memory away?

I am confused

cheers

Rad

I've uploaded the files into /mmc (stm32f4discokit, bikeNomad) and:

No, ROM uage doesn't subtract from available RAM, the .lua files are
only read and it uses no tempfile so it "should work".
How much RAM does the board have?

No, ROM uage doesn't subtract from available RAM, the .lua files are

M

looks like it has 192KB of RAM

http://www.st.com/internet/evalboard/product/252419.jsp


so the 5 lua files:

buffer.lua 16112b
ed.lua 1150b
inout.lua 7076b
mainloop.lua 29271b
regex.lua 9266b

would take away 62875 bytes (61.4KB) ... if all five were to be loaded to RAM, no ?

what's the best way to check for available RAM in eLUA ?

cheers
R.

No, the source code is compiled on-the-fly into a bytecode.
Bytecode is stored to ram then..

thank you!
 I didn't have "allocator=multiple" in my build command.
now I don't get the "out of memory" error when using Martin's Lua based text editor.

perhaps "allocator=multiple" should be added to the build instructions page @ http://wiki.eluaproject.net/STM32F4DISCOVERY

cheers

..basically I run the bikeNomad stuff.. the only changes I did has
been incorporated to bikeNomad already..
1. allocator stuff..
2. stack size 4096..
James did it so it has to work now. Try to take his stm32f4 folder
as-is and do compile with:

scons board=STM32F4DSCY allocator=multiple toolchain=codesourcery
prog

I've made this default for STM32F407VG and 407IG parts.  So it should
now build by default with the multiple allocator.
