Escape double period in image file name

Escape double period in image file name

I use pandoc to make pdf files from my markdown source files.
Generally that works nicely, today I stumbled over a problem when my image 
files contain multiple periods (like 9078505.image.corrected.stretched.png).
In LaTeX I can just "escape" these multiple dots with enclosing the 
filename in two sets of curly brackets.

Now, when I call

In the end I resorted to `pandoc -s input.md -o output.tex` and manually 
editing the file.

Have a great day,

I’m so used to leave out the file ending in LaTeX, that this slipped my proofreading.
I wanted to say that

> ![alt](folder/9078505.image.corrected.stretched.png)

in Markdown should be converted into either

> \includegraphics{folder/{{9078505.image.corrected.stretched}.png}}

or

> \includegraphics{folder/{{9078505.image.corrected.stretched}}}

which both work in (pdf)LaTeX

It seems that the first try (with an attachment) did not go through to the mailing list.
You can find a small test-case in a zip file one can download here: http://cl.ly/ZZ72

The Markdown source works as expected.
The LaTeX source generated with “pandoc -s test.md -o test.tex" complains about not being able to find the image with the multiple periods in it on compiling it with “latexmk -pdf".
I manually edited the LaTeX source (after line 77) to show two correctly escaped file paths.
If the first error is ignored, the document can be compiled.

Thanks for any insight.
David

I’m so used to leave out the file ending in LaTeX, that this slipped my proofreading.
I wanted to say that

> ![alt](folder/9078505.image.corrected.stretched.png)

in Markdown should be converted into either

or

which both work in (pdf)LaTeX

I don’t know if that’s useful or even allowed in this group, but attached is a zip file including a tiny test document.
The Markdown source works as expected.
The LaTeX source generated with “pandoc -s test.md -o test.tex" complains about not being able to find the image with the multiple periods in it on compiling it with “latexmk -pdf".
I manually edited the LaTeX source (after line 77) to show two correctly escaped file paths.
If the first error is ignored, the document can be compiled.

Thanks for any insight.

Re: Escape double period in image file name

[John MacFarlane]

What is your Markdown source here?

When I try:

    ![alt](9078505.image.corrected.stretched.png)

I get

    \includegraphics{9078505.image.corrected.stretched.png}

which has the .png extension, not

    \includegraphics{9078505.image.corrected.stretched}

as you reported.

Escape double period in image file name

[David Haberthür]

[-- Attachment #1.1: Type: text/plain, Size: 1463 bytes --]

Dear all

I use pandoc 1.13.1 on Ubuntu 12.04 to make pdf files from my markdown 
source files.

Generally that works nicely, today I stumbled over a problem when my image 
files contain multiple periods (like 9078505.image.corrected.stretched.png).
In LaTeX I can just "escape" these multiple dots with enclosing the 
filename in two sets of curly brackets.

Now, when I call

> pandoc -s input.md -o output.pdf

TeX complains about an unknown graphic extension (rightfully so).

When I call 

> pandoc -s input.md -o output.tex

I see that the call to the image is correct per se, but should be escaped 
by two sets of curly braces to something like 
"\includegraphics{img/{{9078505.image.corrected.stretched}}}".

Is there some way I can tell pandoc to escape my image paths, do I have to 
rename all my images or edit the resulting .tex file?

Thanks for any insight (and pandoc!)
David
