Revise package does not seem to work for me

pixel · August 6, 2020, 8:34pm

Hi there
I have just tried to install Revise and the usage example given in Home · Revise.jl does not seem to work as expected. I was wondering if someone could point out what I am doing wrong?

The full list of what I am doing is given below, but basically I install Revise, install Example, type “using Revise”, “using Example” and call the function in Example to print “hello, world” to the screen. Then I modify the code in Example.jl so that the message begins with “hi” instead of “hello”, call the function again, but still get the same result. So Revise doesn’t seem to have realised that I have modified the file.

Have I missed some step in installing or using Revise?

many thanks for any help.

Sometimes I have the problem that Revise does not keep up with the updates I do in the code, so I made an habit always call revise(); method_I_just_changed(), can you check if this works for you?

sylvaticus · August 6, 2020, 8:43pm

Sorry to ask but often I forget it… did you save the file after you modified ?

pixel · August 6, 2020, 8:47pm

thank you for the suggestion, but this unfortunately does not work.

pixel · August 6, 2020, 8:49pm

very definitely saved! (and when I exit Julia, restart it and call the function again I get the expected message “hi, world”)

dlakelan · August 6, 2020, 8:53pm

Looking with interest at this, I too seem to experience this kind of issue. I haven’t had a chance to really debug it.

If I type “test Revise” in the pkg Repl mode I find that 5 tests failed. Is this normal or expected? Maybe version 2.7.3 of Revise is not fully compatible with version 1.4.2 of Julia?

Now that is interesting. I wonder why the test results are different when we are both using the same versions?
The 5 tests that fail for me are detailed below, but looking at the runtests.jl file unfortunately didn’t bring any enlightenment as to what the failures actually are or how significant they are, or what caused them.

I give up on Revise and put this function into my code:

function restart()
   atexit() do
       run(`$(Base.julia_cmd())`)
   end
   exit()
end

then I just call the function and julia automatically exits and restarts then when I run my Julia program again it picks up any changes that have been made to modules.

Not elegant, but the best solution I can find.

( the ‘restart’ function originally by fredrikekre, thanks!)
