Weird Tabbing Effects

Weird Tabbing Effects

[Roman E]

Hi all,

I'm a bit of an emacs novice, but I was recently converted to textmate. 
However, when I look at my code (that was written using emacs) with 
textmate (or any other editing program for that matter) the tabbing 
shows up funky. Sometimes there are less tabs then show up in emacs.

Is there any way I can fix these files so that they're viewable in other 
editors? Also, what caused this problem?

Thanks!

Just make sure that all programmes use the same tab width! This value  
can be set on mechanical typewriter machines as well as in  
applications. Well, there is also a side-effect with fonts:  
proportional fonts can make problems.

Isn't vi that text editor with two modes... one that beeps and one  
that corrupts your file?

Maybe there is a mix of tabs and spaces?
Tabs are displayed according to terminal settings and if they are
different in the editors, tabs are displayed differently.
Have a look at variable indent-tabs-mode in Emacs (c-h v
indent-tabs-mode).
Look for tabs in the file and see if some of the tabs have been
replaved by spaces (c-s c-q c-i c-s c-s).

Additionally, emacs by default indents with tabs and spaces.  A tab is 8
chars wide, and if a line should be indented by 10 chars, vanilla emacs
will insert one tab ant two spaces.

Most editors use only tabs or only spaces, and when the tab-width isn't
8 the files you wrote in emacs look weired.

One way to get along with that is to open the files with emacs and do

  M-x customize-option RET indent-tabs-mode

and set it to off (nil).  Then save the files again, and all tabs will
be converted to spaces.

I prefer indenting with spaces, but others milages may vary.

HTH,
Tassilo
