Web Inspector: Add OtherText resourceType and text/plain tokenizer

• Component: Web Inspector (Deprecated)
• Status: RESOLVED INVALID

[Taiju Tsuiki]

Inspector in ToT has tokenizer for HTML, CSS and JS now, and TextEditorHighlighter uses HTML tokenizer as default.
But, I'd like to show a preview for other text file as plain text.

IMO, a possible solution is adding OtherText as another ResourceType and using SourceTokenizer as tokenizer for "text/plain".

I don't think we should add another resource type for this. Resource type are essentially duplicating CachedResource types and we don't want to extend this list.
You should use Other instead.
Backend could decide whether file has text content or not based on the mime type. Binary content should be served to frontend base64 encoded.
(We already have some text detecting heuristics in NetworkResourcesData: http://code.google.com/p/chromium/source/search?q=file%3Ainspector+%22.mimetype+%3D+%22&origq=file%3Ainspector+%22.mimetype+%3D+%22&btnG=Search+Trunk )
Frontend can then show content as text if it is not base64 encoded.

As per comment #3.

I see. OK, I'll go other way than adding OtherText.
As back-end side of NetworkResourcesData does, DOMImplementation::is{Text,XML}MIMEType seems to work for detecting text file.
