Run & Deploy
|
||
|
|
============
|
||
|
|
|
||
|
|
The Run tab allows you to send transactions to the current environment.
|
||
|
|
|
||
|
|
To get to the Run & Deploy module - click the run icon in the icon panel.
|
||
|
|
|
||
|
|
In order to use this module you need to have a contract compiled. So if there is file name in the contract pulldown menu ( in the image below it's the pulldown that says **Ballot**), then you can interact with this contract. If nothing is there - then you need to select a contract - make it the active contract in the main panel, ( in the image below - on the right side of the page - in the main panel - you see the ballot.sol so it is the active contract) then go to the compiler module and compile it.
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
Run Setup
|
||
|
|
---------
|
||
|
|
|
||
|
|
The following settings allow you to directly influence the transaction
|
||
|
|
execution:
|
||
|
|
|
||
|
|
Environment:
|
||
|
|
|
||
|
|
- `JavaScript VM`: All the transactions will be executed in
|
||
|
|
a sandbox blockchain in the browser. This means nothing
|
||
|
|
will be persisted and a page reload will restart a new
|
||
|
|
blockchain from scratch, the old one will not be saved.
|
||
|
|
|
||
|
|
- `Injected Provider`: Remix will connect to an injected
|
||
|
|
web3 provider. `Metamask` is an example of
|
||
|
|
providers that inject web3, thus can be used with this
|
||
|
|
option.
|
||
|
|
|
||
|
|
- `Web3 Provider`: Remix will connect to a remote node. You
|
||
|
|
will need to provide the URL address to the selected
|
||
|
|
provider: geth, parity or any Ethereum client.
|
||
|
|
|
||
|
|
- Account: the list of accounts associated with the current
|
||
|
|
environment (and their associated balances).
|
||
|
|
|
||
|
|
- Gas Limit: the maximum amount of gas that can be set for all the
|
||
|
|
transactions created in Remix.
|
||
|
|
|
||
|
|
- Value: the amount of value for the next created transaction (this
|
||
|
|
value is always reset to 0 after each transaction execution).
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
Initiate Instance
|
||
|
|
-----------------
|
||
|
|
|
||
|
|
This section contains the list of compiled contracts and 2 actions:
|
||
|
|
|
||
|
|
- `At Address` assumes the given address is an instance of the
|
||
|
|
selected contract. It is then possible to interact with an already
|
||
|
|
deployed contract. There's no check at this point, so be careful
|
||
|
|
when using this feature, and be sure you trust the contract at that
|
||
|
|
address.
|
||
|
|
|
||
|
|
- `Deploy` send a transaction that deploys the selected contract. When
|
||
|
|
the transaction is mined, the newly created instance will be added
|
||
|
|
(this might take several seconds). Note that if the `constructor`
|
||
|
|
has parameters, you need to specify them.
|
||
|
|
|
||
|
|
Pending Instances
|
||
|
|
-----------------
|
||
|
|
|
||
|
|
Validating a transaction take several seconds. During this time, the GUI
|
||
|
|
shows it in a pending mode. When transaction is mined the number of
|
||
|
|
pending transactions is updated and the transaction is added to the log
|
||
|
|
(see ../terminal)
|
||
|
|
|
||
|
|
Using the ABI
|
||
|
|
------------
|
||
|
|
|
||
|
|
Using `Deploy` or `At Address` is a classic use case of Remix. It is
|
||
|
|
possible though to interact with a contract by using its ABI. The ABI is
|
||
|
|
a JSON array which describe its interface.
|
||
|
|
|
||
|
|
To interact with a contract using the ABI, create a new file in Remix
|
||
|
|
with extension `*.abi` and copy the ABI content to it. Then in the input
|
||
|
|
next to `At Address`, put the Address of the contract you want to
|
||
|
|
interact with. Click on `At Address`, a new "connection" with the
|
||
|
|
contract will popup below.
|
||
|
|
|
||
|
|
Using the Recorder
|
||
|
|
------------------
|
||
|
|
|
||
|
|
The Recorder allows to save a bunch of transactions in a JSON file and
|
||
|
|
rerun them later either in the same environment or in another.
|
||
|
|
|
||
|
|
Saving to JSON allows to easily check the transaction list, tweak input
|
||
|
|
parameters, change linked library, etc...
|
||
|
|
|
||
|
|
We can find many use cases for the recorder, for instance:
|
||
|
|
: - After having coded and tested contracts in a constrained
|
||
|
|
environment (like the JavaScript VM), it could be interesting to
|
||
|
|
redeploy them easily in a more persisted environment (like a
|
||
|
|
Geth node) in order to check whether everything behaves normally
|
||
|
|
in a classic environment.
|
||
|
|
- Deploying contract does often require more than creating one
|
||
|
|
transaction.
|
||
|
|
- Working in a dev environment does often require to setup the
|
||
|
|
state in a first place.
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
Saving a record ends up with the creation of this type of content (see
|
||
|
|
below):
|
||
|
|
|
||
|
|
In that specific record, 3 transactions are executed:
|
||
|
|
|
||
|
|
The first corresponds to the deployment of the lib `testLib`.
|
||
|
|
|
||
|
|
The second corresponds to the deployment of the contract `test`, the
|
||
|
|
first parameter of the constructor is set to 11. That contract depends
|
||
|
|
on a library. The linkage is done using the property `linkReferences`.
|
||
|
|
In that case we use the addres of the previously created library :
|
||
|
|
`created{1512830014773}`. the number is the id (timestamp) of the
|
||
|
|
transaction that leads to the creation of the library.
|
||
|
|
|
||
|
|
The third parameter corresponds to the call to the function `set` of the
|
||
|
|
contract `test` (the property to is set to: `created{1512830015080}`) .
|
||
|
|
Input parameters are `1` and
|
||
|
|
`0xca35b7d915458ef540ade6068dfe2f44e8fa733c`
|
||
|
|
|
||
|
|
all these transactions are created using the value of the accounts
|
||
|
|
`account{0}`.
