* Use babel-code-frame for syntax errors
* Support the `--color` option more explicitly
* Update rollup config to handle babel-code-frame
* Use exact dependencies
This PR adds two things:
`--debug-print-doc` command that prints the formatted doc
```js
echo "<div><</div>" | ./bin/prettier.js --stdin --debug-print-doc
[
groupConditional(
group([
group([ "<", "div", group([ indent(2, []), softline() ]), ">" ]),
"<",
"</",
"div",
">"
]),
[
group([
group([ "<", "div", group([ indent(2, []), softline() ]), ">" ]),
"<",
"</",
"div",
">"
]),
group([
group([ "<", "div", group([ indent(2, []), softline() ]), ">" ]),
indent(2, groupBreak([ hardline(), "<" ])),
hardline(),
"</",
"div",
">"
])
]
),
";",
hardline()
];
```
The ability to view the IR in real time on the browser display:
The way it works is pretty cool, we take the doc IR and print a valid JavaScript string out of it, that we then send to prettier in order to make it look good :)
It doesn't compile cleanly anymore:
- esutils checks for Buffer.isBuffer without ensuring that Buffer exists.
- for version, we require a json file, need a rollup extension for that.
I no longer hardcode the version number.
Note: we need to merge this pull request after we have done the release so that the version number is correct and need to rebuild the minified version in a subsequent commit.
This is a very handy way of playing out with prettier without having to install it. People have already been using it actively in the issues. Putting it directly inside of the repo would be better than on mine.
