Reduce search_index.js size

[Xuhao]

Is there any way to reduce search_index.js file?

👍 Becomes > 20MB sometimes...

Reduce in what way? minify, etc?

[manuelmeurer]

AFAICS it's already minified and I guess it has to be that large to support searching for all possible keys. Could it maybe be loaded asynchronously so the user doesn't have to wait for it?

[kgrz]

Looked at the code for a bit and understood that any change to how the index file is generated (or an async JS snippet for loading the index file) should actually be incorporated into rdoc. Right @zzak?

[kgrz]

@Xuhao FWIW, Gzipping the file will reduce the size by a HUGE margin. This, however, won't work if the files are being served from the filesystem — in which case, having a large file is not really a problem anyway.

[kgrz]

Went ahead and implemented that Gzipping functionality into sdoc: kgrz@43c1aad

(Work in progress. )

@zzak should we have something like that?

👍

@kgrz Any update on this?

[kgrz]

Nope, will give this a another shot this week. The current code doesn't work as expected. Minor file-naming issues. My initial idea was that a gzipped index file should be generated which can be served by the server when the browser supports it. I still have add that part of the code.

Hey! Sorry this is old news now, but I wanted to point out:

• As of RDoc 4.2.0 (released with JsonIndex#generate_gzipped ruby/rdoc#334) JsonIndex will generate gzipped javascript files

👍 Thanks for implementing!
