editing large files

editing large files

[Sebastian Luque]

Hi,

I need to edit some relatively large files (~ 200 Mb), so I'm exceeding
the maximum buffer size allowed by my Emacs (GNU Emacs 21.4.1
(i486-pc-linux-gnu, X toolkit, Xaw3d scroll bars) of 2005-10-02 on
trouble, modified by Debian).  Searching for solutions it seems that the
only way to do this would be to use a 64-bit machine and Emacs.  Is this
correct?  What alternatives are people using on a 32-bit machine?


Cheers,

emacs-snapshot has a max buffer size of 256MB, xemacs of 1GB (IIRC).

For large files, I usually just split them up, do my editing and then
join them back together again. If the changes I need to make are
repetitive or fairly easily specified in a programatic fashion, I just
use sed.

Thanks to all of you for your suggestions.  Indeed, I ended up using AWK,
since they were all comma-delimited files (tables).

Indenting in HTML mode

[Tyler]

Hi,

I'm trying to edit an HTML file, and I am unable to indent lines with 
the tab key. The only thing that I've managed to make work is to mark a 
region, then C-x tab to indent that region by 1 space. Also, on text I 
have yanked into the file from the clipboard I can tab as expected. 
However, all the text I entered directly into Emacs is 'protected' from 
tabbing. What am I doing wrong?

Thanks,

Tyler

What html-mode are you using? I assume you are using
html-helper-mode. This mode only seems to indent lists, selects and
tables. Modes which handle the indentation of other elements properly
are psgml-mode and nxml-mode, maybe you should try one of those. They
are not yet part of emacs, though.
