Bug: inline images for filenames with spaces

Bug: inline images for filenames with spaces

[Huy]

Hi,
inline image display doesn't seem to work for image links with spaces in
them.  However, clicking on the image links does work: a window shows
the image.

Example:
[[file:img/test.png]] will display inline
[[file:img/test copy.png]] won't

I'm using the latest org-mode sources in git as of a few minutes ago on:
GNU Emacs 23.3.1 (x86_64-apple-darwin, NS apple-appkit-1038.35) of
2011-03-10 on black.porkrind.org

Thanks,
Huy

Just tested on the same emacs version and few minutes old org-mode and
both works for me. How do you export? Do you have some special settings?

I'm not exporting.
I'm just doing C-c C-x C-v to display the inline images within emacs.

I confirm there is a bug here, I'm on it.

That's because those images will be inserted as

[[file:image%20with%20space.png][file:image with space.png]]

and such a string is not recognized by the inline displayer.

The attached patch fixes this. 

Please confirm and also take the time to check that there is no
side-effects -- especially wrt the exporter.

E.g. this LaTeX command:

  \includegraphics[width=10em]{image with space.png}

will result in a problem, with the string "with space.png" just
next to the picture.

In any case, it's better to avoid spaces in file names.

Thanks for reporting this,

Subject: [PATCH] org.el: don't escape image links with no description.

(org-make-link-string): Don't escape image links when no description
is provided by the user.  Otherwise those images won't be recognized
as images when trying to display inline pictures.

That's because you need to actually test this:


[[file:img/test.png][file:img/test.png]]
[[file:img/test%20copy.png][file:img/test copy.png]]

... where you can reproduce the error.

I've tested your patch. It works with org-toggle-inline-image, export to
HTML and to LaTeX.

AFAIU, now a link to an inline image inserted with org-insert-link will
expand into [[file name.jpg]] instead of [[file%20name.jpg][file
name.jpg]].  But the later form still doesn't work so it have to be
fixed into older org files.

Best,

Sorry, it took me long to get back.

I confirm that the current repo fixed it, bt I can't confirm exporting.
I don't know how to do any exporting yet.

Thanks for the fix!

Hi Huy,

Thanks for confirming the fix is okay!

Try the magic keystroke in any Org file: C-c C-e
