- Fri Nov 21, 2014 4:36 am #3050 Hi,

some remarks/questions about the file - functions:

- It already happened twice that I suddenly couldn't write to a file anymore - module restarted on every file.open("test.lua","w+"). Seems to happen after many writes to the same(?) file (I uploaded very often..). Re-flashing firmware solved the problem but I would like to know if this is hardware-related or maybe a bug in the internal 'fileystem'?

- It would be great to have a file.exists(filename) function (or maybe file.open() returning a boolean instead of throwing an error on failure).

- Is it possible/planned to be able to open more than 1 file at once?

- (minor) I think file.list() should not print the listing by default, just return the table. Maybe file.list(bool printit)?

- (very minor) The example for file.list() in the docs should be "for k,v in pairs(l) do" not "for k,v in l do"

Again - many thanks for your work!

- Fri Nov 21, 2014 11:19 pm #3112 Had the same problem, but mine was a bit tricky it was also the init.lua

Whenever i tried to file.open it or file.remove it i had a restart, but module was able to boot and work as if everything is fine.

Also sometimes, i had 4 files with the exact same name

Ow, btw, to fix (to remove) the init.lua file, i had to reflash the firmware :/

I will give more test to file api. one of guy I know report a same name files too... It's definitely a bug.
currently file.open will close the file opened before if user forget to close it.
only one file supported now. it's getting complicated if multiple files opened, like the lua io module.
file.list() print to serial will be removed in next build.
doc fixed.
