How can I do this with rshell, and is there a way to capture the output?

I think the idea is that you use the "repl" command to get to the MicroPtyhon prompt hit Ctrl-D to soft reset (if you've previously loaded this file), then run "import blink"

Code: Select all

rshell> repl ~ import blink~

to enter the repl and run the command and then back to rshell.

No joy. The above may be due to my unfamiliarity with python, as my simple example code is not a class per-se, but it should be easy to just 'run' the file similar to how ampy does.

Normally I use screen to enter REPL. I recently use rshell as IDE
rshell -p /dev/ttyUSB0 --editor nano --buffer-size=30
/home/wr300000> repl <---- get in repl and release machine.reset() to rerun my main.py

Below is result from my main.py showing normal /sd directory and other configured variables.

Why did rshell Iist command effect to main.py ?

You also need to cp blink.py to the device.

The way I work is as follows. I use a programmers' editor (Kate) to edit a file, say myfile.py. Assume I want to run myfile.main(). From the directory containing the file I run rshell. Let's say the target is a Pyboard with an SD card. At the rshell prompt I issue ctrl-x takes you back to rshell.
Note this can be streamlined, so after ctrl-x all you need is an uparrow to run an edited version:

ARGH, it was on the device, but I must have fat-fingered it.



Thanks (I feel stupid now).

This would work for me, but many of the example programs I'm using haven't defined a main method, so it appears that just Is probably adequate for them.

[ I still think having a run command would be faster and more intuitive, but I'll quit whining now.... ]

Thanks everyone!

I'm not sure what you're advocating but you could look at pyboard.py to see if that fits the bill.

An rshell line like the one I posted (which is easily adapted for your case with no main() function) gives an extremely fast edit-test cycle because of rshell's ability to recall previous lines.

Would it be possible to tag new releases of rhell in the repo and also mark them as releases on https://github.com/dhylands/rshell/releases (in addition to the releases on PyPI)?

This would make it easier for distribution package maintainers to get notified about new releases (I recently took over maintenance of the rshell AUR package).

Yeah - I could do that.

I added releases for 0.0.27 and 0.0.28

Very nice.Thank you.
