I
okay hello everybody I'm very glad to be
here today and to present you remix the
remix is a delegate or where ever got to
that can debug smart contracts so I am
young I'm walking for this weave the CPP
team together with Christian the anatomy
tree bobbin and hike and babble so
actually the name is remix we already a
devil girl right here it was mix and
Nick's was completely integrated inside
this BPM suite but we have decided for
some reasons to reboot the project from
scratch and to start remix I mean the
main reason of that was that as the
community grows grows and grows it is
more valuable now to propose new tools
that can be integrated inside other
application then to have a single closed
application I mean I will prefer say it
I will prefer say it okay you can use
plug-in that you can integrate in your
application that you like to use then to
say okay we have read Hemi will be mixed
you have to use me you have to use this
because it is the only application so
it's better to have something that can
be integrated in other application then
to have some synchros closed so that
wise remix is born so we have taunted
the roping remix a few months ago
basically is just a vm table girl you
can see a screenshot here and this
screenshot SB tanker has been taken from
the atl can integration so we have basic
features of vm debugger it's okay
we are walking now on having full
integration of this debate go inside 3dt
so you can debug smart contracts using
3d to this remix has been developed
using javascript technologies you can
use it using LPM so we can pull RemX
using NPM and you can use some modules
of remix with node and the main reason
of all that is just to give to the
community new tools that can be used to
debug easily smart contract so this is
the integration of remix in 3 DG so we
have basic features of an ID like source
code debugging that's most earth-like
record manager coming soon and like
several crackers like contractor rain
tracker and as the locals variable
striker so we have to part the vm
debugging stuff and also does ready 3d
doing stuff and I guess that the most
interesting part will be 3dt derivative
so i will i will just do a short demo to
present you our stuff oh yeah
all right it's not okay
okay so here i have one integration of
hemmings inside browser solidity brother
3dt is text editor is a solidity editor
that's includes a compiler so we can
just write smart contract and you can
compile but contract and also it has
some features of niid because you can in
you can in the right panel here credit
transaction so you can in the browser
write contracts and then test contract
in in an environment so this is not
remix this is only brothers ready to sew
in which under elements will I will
deploy this this contract I can choose
and I have two possibilities the first
one is to use the embedded JavaScript vm
so in that way I will just run the
execution on this contract is inside the
bottom and everything will be inside the
Rossum every transaction will be
deployed inside the browser or i can use
an external web free object so i can
just connect the browser to some kind of
external node and i have a note here
which is here you can see that on the
upper left corner i am using the cpp
italian clients which is why i have run
this application in test mode it means
that i can just mine mine and mine every
five seconds here and I come just deploy
contract test it without from scratch
and so on so don't care about what is on
the right side here I just have a node
which constant which is concerns
constant remaining
okay so i can just deploy this contract
waiting for us to be mines okay i have
two principal methods functions in this
contract don't care so much about the
code here it's not the principal step
that i want to show you so the first is
the four back function and the second
one is the move fund function so this is
a donation contract basically i will i
can just give it to this contract and
then the owner of the contrite can live
draw so meteor from this contract so
let's say that i will send 1080 are here
okay i will call the fallback function
here i have to wait a little bit okay so
i have some details about the
transaction here but yeah let's skip
that for now and then on the right side
here i can start debugging this
transaction okay
can you see it yeah we just okay so now
I debug transaction so I have launched
remix here which is so modules that
roams inside possess ready team and I
can stand about debugging my contract
here I can't go forward and I can go
backwards and I can see here location in
the source code well he's do execution
going here so i have two important
features here the first is a source
location as you can see here and the
second one is as all to paneras in the
right side you can check out here the
state of the contract so you can see
that the variable just call giver here
is going from 0 to the address of the
sender etc and you can also check out
local variable here ok i will now just
call this function here re i have to
copy and past stuff here and i will call
so the movement function with two
parameter the first one is the address
where i will send it here and the second
one is the amount of a tower so this is
not so much now this is only one way ok
and i will just call my phones ok i have
some details about transactions not
important and i can start debugging and
then i can throw the execution of
the transaction here now i am in only on
your motif here here i can check out the
bed ends which is recalled behavior here
now i am in the two cents in the same
function and it will send is successful
successful sorry i will just trigger the
found moved events here yes sir it is
that's readable but yeah okay so i have
sauce location inside process for EDT
thanks to remix and i have the contract
state with all variables that are
decoded i have the rockers and i can
also up sorry i can also obviously check
out some all values like the stag
straight changes the memory and recall
data ok so that's for the short demo
here what's next
okay so this is the remix integration
inside process validity what's next I
think we could easily imagine that remix
could be integrated in several other
tools today we talked about troffer
pepper we talked about FIM studio we
talked about mists and meta mask and so
on so it's it will be really easy to
enter right remix to this debugger
inside all those tools because all those
tools that I PCD prefer are made for
development proposed so I think the good
things to have a 3g debugger inside
those tools already and it is really
easy to use just have to pull the NPM
module and then you just have to create
to instantiate the object into render
remix inside your HTML file this is here
sir remix is available as an MPN module
but more of that we also provide some
kind of low-level tools in javascript
also that can be used by ever ability to
create new tools and to imagine new use
cases for example here you have trace
manager which is a tool that you can use
to check out some value in the vm trace
it provides an API to easily retrieve
value from the vm trace you have mapping
decoder which provide an API to deal
with the source location in this
religion tracked you have an HD worker
that is used to crawl into work over all
the nodes of this radici contract and
obviously you have also decoder so you
can use those tools to extend your tools
to create new tools and to also imagine
new use cases with
and I think that is really important
features to provide api's and not to
build a closed application so what we
already don't we have already walked on
the integration of RemX in meta mask in
East if you go in each Afghan you can
already use mix now and as I shown you
just now you can use also linux inside
validity so now this is a personal
opinion what I want to keep in mind and
what maybe we want we need to keep in
mind is the first developing
transactions with remix all or other
tools can be used to debug transaction
that are already committed in the block
chain is a private block chain or
liberal chain whatever and I think these
really nice features because for example
if now you come to me and say I en can
you debug these transactions in the
public blockchain i will have to check
out every up codes i will have to check
out the vm trace of it will be very very
long yeah and so this is why I think
this is really nice to be able to dip a
concession that are in the main chain so
only you can easily integrate remix
inside other up and then as I said it
provides a low-level API ok what's next
we need to commit this walk on the
stratum car tracker we need to finish
the backbone manager we need to do a
scenario builder we need 12 for
integration inside the ETA on vm is ESPN
and we have to do the mist integration
and obviously as his napi we have to do
a lot of documentation a lots of the
foundations and yes so we had to finish
that I would just say that you can go to
check those links you can use him it
please you can integrate hynix in your
application please please please and you
can also contribute and I will be very
happy if you can just integrate clinics
in your application and if you can
contribute on improving linux as well
because i think it's really important to
share and to do stuff together so yet
text for listening and see you soon
thank you young
you
