Open a ~15MB file

[rodrigokiller]

I know that this file is really big, but, I dont know why I can open it in Notepad++ with hex plugin, for example, and here I cant.
Thanks

Unfortunately, it's due to VS Code limitation, see microsoft/vscode#21869

Hello @stef-levesque . I think that it is no more a VS Code limitation. I tried and now I can open files more than ~15MB. I tried a 26 MB file and it opened in VS Code. And, in the link provided by you, alexandrudima could not reproduce the issue and the issue was closed.

Thanks to the memory fixes in microsoft/vscode#30180 , the bottleneck is no more coming from memory, but from the time it takes to process the output of hexdump and display the actual TextDocument.

i.e. If you set hexdump.maxLineCount to 1000000, you can't open hexdump on a large file (~15Mb). But if you first open it with the default hexdump.maxLineCount and once it is open, increase hexdump.maxLineCount to 1000000, it will eventually update the already-opened hexdump TextDocument.

I'll take another look, and see if I can provide a limited "preview" before loading the whole file in the background.

@stef-levesque thanks Stef, I know that I can use a editor that focus only in the hex edition, but, I really love Visual Code and it would be nice to have an actual good option to those old hex editors.

@rodrigokiller version 1.6.0 of this extension should better handle large files. You can try to set hexdump.sizeDisplay to 15728640 for displaying a full 15Mb file, but due to a VSCode limitation, the color syntax won't work.
