[with patch, positive review] jsMath, favicon, and logo for live, static, and offline docs

[mpatel]

A few changes to

* Enable jsMath in static and offline docs.

* Display a Sage favicon in static and offline docs.

* Display a Sage logo in live, static, and offline docs.

"Offline" docs are just those accessed via  file:///.

I'm not sure whether/how Mercurial handles binary files, so I've attached two patches. One mentions the added favicon and logo files; the other doesn't. To get the png files themselves in the right place, I first created doc/common/static. Then, in this directory I did

wget http://www.sagemath.org/pix/sageicon.png

and

ln -s ../../../../../data/extcode/notebook/images/sagelogo.png .

I've attached these, too.

Note: There's a favicon.ico in the same extcode directory, but it's not transparent. There is another sagelogo.png in SAGE_ROOT/data/extcode/images, but its dimensions are larger.

The jsMath issue was mentioned on sage-devel:

 http://groups.google.com/group/sage-devel/browse_thread/thread/40eab3f9610e061d/eb93a3930e79ea3a?#eb93a3930e79ea3a

The favicon and logo were mentioned in connection with a doc sidebar toggle:

 http://groups.google.com/group/sage-devel/browse_thread/thread/8c8fe7c5d0c0f725/4807f5553bdbd6b0?#4807f5553bdbd6b0

I'll make a separate ticket for the toggle.

[mabshoff]

To create a patch that contains a png you need to export a git style patch. Then export two patches, one for the Sage library and one for the ext repo. The names should be

• trac_5799_sage_$FOO
• trac_5799_ext_$BAR

respectively. It is generally a good idea to split tickets into independent tasks, i.e. this is a borderline case and can be done via one ticket.

This also strikes me as kind of odd:

<script type="text/javascript" src="../../../../../../../local/notebook/javascript/jsmath/easy/load.js"></script> 

given that everywhere else we use

<script type="text/javascript" src="/javascript_local/$FOO"></script>

but that might be unavoidable.

Cheers,

Michael

To create a patch [...]

Thanks for the tips! Take two attached.

This also strikes me as kind of odd:

I'm about to attach an alternative to trac_5799_sage_jsmath_doc.patch.

[mpatel]

Somewhat less efficient alternative to trac_5799_sage_jsmath_doc.patch.

[mabshoff]

Cool, I deleted the old patches to make the history cleaner. If you post updated patches you should also change back the summary to "needs review". I did that in this case already.

Cheers,

Michael

I applied the 'ext' and 'alt sage' patches, and tested "en/tutorial html". It all looks good.

[mpatel]

Better cross-browser favicon support. Goes with trac_5799_sage_jsmath_doc_v2.patch.

[mpatel]

Better cross-browser favicon support, auto relative paths. Apply trac_5799_ext_icons_v2.patch first.

[mpatel]

The *_v2 pair replaces the earlier versions.

• Same sageicon.png as in the first patch.
• ImageMagick gives a "true" ico file: convert sageicon.png favicon.ico.
• Tested in FF3, O9 on Linux, and in Cr2, FF3, IE8, O9, S3 on Windows XP. Whether the icon is transparent and visible for live, static, and offline docs is browser-dependent.
• Automatic relative paths for the favicon, logo, and jsMath. This is important, e.g., in the reference manual.
• #4714 should take care of the unknown jsMath macros.

[jhpalmieri]

Looks good. Positive review.

Does this mean that we should make --jsmath the default for building html docs? It's much faster than building without using jsmath.

I think \QQ and friends generate an unsightly error message. I'll try to learn how to make an spkg, for #4714 and #5447.

In order to get the sage -sdist command to work after applying this patch, I had to copy all of the files over to doc/common/static as actual files, since something in the build system could not find the files as links. I will post the extra patch on this ticket, which was necessary to roll sage-4.1.rc0.

No point in posting a huge patch, so here is a link:

 http://sage.math.washington.edu/home/rlmill/trac_5799-unlink.patch

[mpatel]

The new patch seems to have the same observable effect as the previous set in the usual browsers on Linux and Windows XP. But the AMS symbol font msbm10 won't be available in the static and offline docs.

I'll venture that having extra copies of the favicons and logo in the Sage tree is not a big deal. Ideally, jsMath should have a single home, e.g., so that planned changes (cf. #4714) to easy/load.js affect the live, static, and offline docs equally.

Perhaps we can make the symbolic link itself in jsMath's spkg-install. Does this mean we should remove the link from version control? If so, we're [almost] done.

[rlm]

I'm worried, since a fresh install of sage-4.1.rc0 is missing most of these files in doc/common/static:

[geom sage-main]$ cd doc/common/static/
[geom static]$ ls
total 4.0K
drwxr-xr-x 3 rlmill rlmill 4.0K 2009-07-04 14:18 jsmath
[geom static]$ ls jsmath
total 16K
-rw-r--r-- 1 rlmill rlmill  12K 2009-07-04 14:13 COPYING.txt
drwxr-xr-x 3 rlmill rlmill 4.0K 2009-07-04 14:18 fonts

Has anyone tested a fresh build of sage-4.1.rc0 to see if things related to this ticket work?

[rlm]

I'm seriously thinking about reverting this ticket, since there are obviously some assumptions the sdist script is making, which are conflicting with the solutions used for this patch. For now, I'm reopening the ticket, until I can get this resolved one way or another.

[jhpalmieri]

This is a bit of a shot in the dark, but does trac_5799_manifest.patch help?

I think this is what I was looking for. Thank you!

[rlm]

trac_5799_manifest.patch merged in sage-4.1.rc1

[rlm]

As suggested by William, the MANIFEST.in changes were reverted to just adding the line recursive-include doc/common/static *.

 http://docs.python.org/distutils/commandref.html#sdist-cmd

[mpatel]

Is it possible to include symbolic links in MANIFEST.in? Unless I'm wrong, we now have jsMath installed in doc/common/static and javascript_local. Do we really want this? Besides putting upstream code under version control in the Sage library, this complicates, e.g., the resolution of #4714.

[rlm]

Replying to mpatel:

I had wondered this myself. The only way to know for sure is to try it, roll a new source tarball (via sage -sdist), install the "new version," and see whether the notebook still works...

Attempt to get distutils to preserve symbolic links.

This patch alters setup.py so that it preserves symlinks. However, I'm far from convinced that it's the right approach. Is it possible to identify and copy broken links in Python? In particular:

• In sage_findall(), can we refine or avoid using the exception handler? Perhaps it's better to use  os.walk(), but the os.path.is*() family actually follows symlinks.
• Is there a Pythonic analogue of cp --preserve=links --no-dereference?

Possible alternatives:

• Make a symlink in some spkg-install.
• Have Mercurial reconstitute the link.

[rlm]

We really need to create a new ticket for this issue and continue there. I would also suggest taking this up on sage-devel.
