Syntax Highlighting

When developing smart contracts for CashScript it is useful to have the proper syntax highlighting in your code editor / IDE. If you use Visual Studio Code, there is a dedicated CashScript extension. For other editors it is recommended to install a Solidity highlighting plugin and associate it with .cash files in your editor, since the syntaxes of the two languages are very similar.

For Visual Studio Code a dedicated CashScript extension was developed by community contributor Nathaniel Cherian. This plugin works with .cash files and supports syntax highlighting, autocompletion, snippets, linting and even integrated compilation.

Because of the first-class CashScript support, Visual Studio Code together with this CashScript extension is the recommended way to develop CashScript contracts.

Sublime Text

The most popular Solidity plugin for Sublime Text 2/3 is Ethereum. Install this plugin with Package Control, open a .cash file and set Solidity as the syntax language in the Sublime menu bar:

View -> Syntax -> Open all with current extension as ... -> Solidity

This associates .cash files with Solidity, and enables syntax highlighting for your CashScript files.

Atom

The most popular Solidity plugin for Atom is language-solidity. Install this plugin and add the following snippet to your Config file:

```yaml title="~/.atom/config.cson" core: customFileTypes: "source.solidity": ["cash"]


This associates `.cash` files with Solidity, and enables syntax highlighting for your CashScript files.

## Vim
The most popular Solidity plugin for Vim is [vim-solidity](https://github.com/TovarishFin/vim-solidity). Install this plugin and add the following snippet to your `.vimrc`:

```bash title=".vimrc"
au BufRead,BufNewFile *.cash setfiletype solidity

This associates .cash files with Solidity, and enables syntax highlighting for your CashScript files.

GitHub & GitLab

GitHub and GitLab have syntax highlighting for Solidity built in. To associate .cash files with Solidity highlighting, add a .gitattributes file to your repository with the following contents:

python title=".gitattributes" *.cash linguist-language=Solidity # GitHub *.cash gitlab-language=solidity # GitLab

Others

If your editor is not mentioned above, the steps are likely very similar. Try to find a Solidity syntax highlighting plugin for your editor of choice and find a method to associate .cash files with this Solidity highlighting.
