Parse errors

[drandreaskrueger]

Fantastic, I have been looking for s.th. like this for a long time; really happy solgraph was mentioned in Hudson Jameson's DevCon3 talk last week.

Small issue - I get parser errors for some contracts.

How to replicate:

git clone https://github.com/raiden-network/raiden
cd raiden/raiden/smart_contracts/
find . -type f -name "*.sol" -printf "solgraph %p > %p.dot\n" | bash
find . -type f -name "*.dot" -printf "dot -Tpng %p > %p.png\n" | bash

8 out of the 10 contracts are fine, but for two of them (ChannelManagerContract.sol & Token.sol) I get these parser errors:

Parse error
{ SyntaxError: Expected "contract", "import", "library", "pragma", comment, end of input, end of line, or whitespace but "i" found. Line: 3, Column: 1

These are all the images of those contracts which succeed getting parsed: raiden-solidity-solgraph-for-printing.pdf Really great, thanks a lot!

[raineorshine]

Thank you! This should be remedied as soon as we upgrade to the latest version of solidity.

[raineorshine]

Fixed in v0.3.0.

Only omission is that constructor and fallback are being labeled null. Tracked in #28.

@drandreaskrueger Just fixed the babel error and published to v0.3.3

[drandreaskrueger]

this now seems to work fine:

git clone https://github.com/raiden-network/raiden-contracts raiden-network_raiden-contracts
cd raiden-network_raiden-contracts/raiden_contracts/contracts/
find . -type f -name "*.sol" -printf "solgraph %p > %p.dot\n" | bash
find . -type f -name "*.dot" -printf "dot -Tpng %p > %p.png\n" | bash

and there is one png file for each sol file:

find . -type f -name "*.sol" | wc
     17      17     442
find . -type f -name "*.png" | wc
     17      17     578
