This is considered a feature?

Well... When did you last see one that big? But I don't know why they
bothered to put in such an arbitrary restriction.

I first parsed "truncates files ... while loading" as "if you
accidentally try to open such a file, the editor will destroy it", but
I suppose only the editor /buffer/ gets truncated.

I think the implication is that the previous behavior was to truncate
the file on load and then let it be edited as normal (less the end of
the file). The new behavior is clearly an improvement over that.

People sometimes turn quite large database into multi-gigabyte xml or json.
Most text editors will start to act oddly. Some can handle such files ...
with a plugin at least: http://www.vim.org/scripts/script.php?script_id=1506

Well, previous behavior was to run out of memory in 32-bits and load file just fine in 64-bits, unfortunately over 1GB it takes too long to load (like tens of seconds long).
 
As for the purpose of loading such big files, I regulary need to load big and edit 800MB backend logs.
 
BTW, we are quite proud that theide can even edit such long files and load them relatively quickly (like 200MB/s from SSD). You can try with any existing source code editor - most of them crash or freeze at 100MB :)

You are welcome. I would appreciate a report here when you have tried it out.

"Popular search engines such as Google, Bing, Yahoo!, Wikipedia, Amazon,
YouTube and Baidu are used to calculate the ratings." which explains why
Algol isn't there ;) - nobody uses it on the 'Net!
