Tx parser (`txparse`)

This is a very simple utility, which reads line by line from standard input. For each line, it tries to interpret it as hexadecimal data, and the data as an Ethereum transaction.

If all goes well, it outputs a line containing the address of the sender. Otherwise, it outputs err: and a suitable error message.

Build instructions

There are few options to build txparse tool like any other nimbus tools.

Use nimble to install dependencies and your system Nim compiler(version <= 1.6.0).
```
$> nimble install -y --depsOnly
$> nim c -d:release tools/txparse/txparse
```

Use nimbus shipped Nim compiler and dependencies.

$> make update deps
$> ./env.sh nim c tools/txparse/txparse

Use nimbus makefile.
```
$> make update
$> make txparse
```

Example:

$ cat ./sample.input | ./txparse
err: t is not a hexadecimal character
err: m is not a hexadecimal character
err: hex string must have even length
err:   is not a hexadecimal character
err: Read past the end of the RLP stream
err: The RLP contains a larger than expected Int value
