Setting file extensions to be handled by gpg encryption problem

Setting file extensions to be handled by gpg encryption problem

[bar tomas]

Hi,

I'm using gpg to encrypt files and I would like that files with 'txt'
extension be treated like 'gpg' files.
I read in the doc that this can be controlled with the variable
epa-file-name-regexp
So I added the following line at the end of my .emacs file

(setq epa-file-name-regexp "\\.txt$")

But this has absolutely no effect. I mean, if I create a txt file with
emacs, when I save it I would like for emacs to ask for an encryption
paraphrase, but it does not.

I have very little knowledge of the .emacs file, so maybe the line I
added is wrong?
Many thanks for any help

I just tried, it indeed does not work with that line only.
You have then to call `epa-file-name-regexp-update' to make it works.

cf describe-variable epa-file-name-regexp
,----
| epa-file-name-regexp is a variable defined in `epa-hook.el'.
| Its value is 
| "\\.gpg\\(~\\|\\.~[0-9]+~\\)?\\'"
| 
| Documentation:

| have to call `epa-file-name-regexp-update' after setting it to
| properly update file-name-handler-alist.  Setting this through Custom

Many thanks!
I defined it in custom-set-variables in the .emacs init file, as
suggested in your post and now it works directly:

(custom-set-variables
'(epa-file-name-regexp "\\.txt$"))

Thanks again.

Re: Setting file extensions to be handled by gpg encryption problem

Hi,
I just realized that the problem of writing

> (custom-set-variables
> '(epa-file-name-regexp "\\.txt$"))

as I put in my previous post to force emacs to treat txt files with
gpg encryption is that files of extension gpg then do not trigger the
gpg mode.
I tried wrting a regular expression that would include both txt and
gpg extension files like this:

(custom-set-variables
'(epa-file-name-regexp "\(\\.txt$\)\|\(\\.gpg$\)")
)
But there must be an error in my regular expression, because it doesn't work.
Many thanks for any help pointing out my error

You want something like:

   (custom-set-variables
   '(epa-file-name-regexp "\\.\\(txt\\|gpg\\)\\'"))
or
   (custom-set-variables
   '(epa-file-name-regexp "\\.txt\\'\\|\\.gpg\\'"))

In a string (i.e. with the "...") a \( is just the same as a (, so it's
important to double your backslashes in order for them to be visible to
the regexp engine.

Note how I used \' (match the end of text) rather than $ (match the end
of line).

I haven't actually tried it, but it looks like you mean "(\\.txt$)|(\\.gpg$)"

Re: Setting file extensions to be handled by gpg encryption problem

[bar tomas]

Many thanks for your help, but the regular expression you suggest
doesn't seem to capture file names with extension txt or gpg.
I've tried to test it in an emacs buffer and tried both
(\\.txt$)|(\\.gpg$) and (\.txt$)|(\.gpg$) but it doesn't seem to work
either.
Many thanks for any help

I think you need to escape the parentheses too. Try,

\\(\\.txt$\\)\\|\\(\\.gpg$\\)

Here is the default regexp:

"\\.gpg\\(~\\|\\.~[0-9]+~\\)?\\'"

Here what you could use:

"\\.gpg\\|\\.txt\\(~\\|\\.~[0-9]+~\\)?\\'"

You don't need two groups.

The second part of the regexp is needed if you want that backup files
of your encrypted files be encrypted (e.g toto.gpg ==> toto.gpg~4~)

Tomas,

I believe that

  (custom-set-variables 
    '(epa-file-name-regexp "\\.\\(txt\\|gpg\\)$"))

may be what you're looking for.

Many thanks for all the replies. It works now.
