Open URLs with # using cygstart.exe

Open URLs with # using cygstart.exe

[Alexander Konovalov]

Dear Cygwin experts,

I am trying to open the exact location in the html file using my default 
browser with the command of the form

cygstart.exe file:///C:/somepath/doc/ref/chap31.html#X84F59A2687C62763

However, the anchor is ignored, so instead of going to the exact location
it opens the file and stays on the top of the page.

I didn't manage to find anything on Web, except the discussion about
handling '?' in URL on March 30-31 this year, but it doesn't help.

Is there any workaround to handle '#' in URLs?

Thanks,
Alexander

Hi Alexander,

You are doing better than me. For me, cygstart interprets the anchor
as part of the filename.

$ cygstart file:///www/pages/html401/sgml/dtd.html#inline
Unable to start 'C:\cygwin17\www\pages\html401\sgml\dtd.html#inline':
The specified file was not found.

Have you tried

cygstart.exe 'file:///C:/somepath/doc/ref/chap31.html#X84F59A2687C62763'

(note the single quotes) ?

Same here.
Interestingly, it works just fine with the remote URL - it brings up
the page in the right place.
(OK, so here it's Windows 7 (32-bit) running Cygwin 1.7.15, and the
default browser is Firefox)

Re: Open URLs with # using cygstart.exe

[Alexander Konovalov]

Hi Dima, Csaba,

Thanks for replies. I am running 64-bit Windows 7, Cygwin 1.7.11 (2012-02-24).
The default browser is Chrome, but I've tried with Firefox and InternetExplorer -
same result whenever I'm using single quotes or not with each of the three
browsers. Remote URLs indeed work fine. With the local URL address line of the
browser contains truncated URL without '#...' part so maybe cygstart parses
its argument differently dependently whether it starts with file:// or http://?

Thanks,
Alex

This is entirely a Windows issue.  You'll get the same behaviour if you drop
that string into a Windows Run dialog.

I've no idea what the solution will be, but I very much doubt it'll be Cygwin-
specific.

Just say no to http://cygwin.com/acronyms/#TOFU

Also, you've got a fairly old version of cygwin there...

Cygstart does not actually parse general URIs. For a long time it had a 
special case that tested explicitly for `http:', and recently added 
`mailto:' after a similar issue arose [1]. Ironically, most URIs seem to 
work precisely because cygstart *doesn't* know what to do with them and 
passes them along as-is, giving Windows a chance to do the right thing.

Actually, you can probably ignore this and go with what Adam posted...

One can run a local webserver and talk to it via http. Given that the
webserver might be a very lightweight one, it would not be much of an
overhead.

(Of course I know it would add a bit to the complexity of running GAP
on Windows :))

Just check the command like the browser was started with to narrow down the
possible source root of issue.
Also, please don't top-post.

That's correct.  And before you waste too much time on this, you should 
make sure that you have the latest cygutils package installed.  The 
behavior of cygstart with respect to file:// URLs changed starting with 
cygutils-1.4.10-1.  See

   http://cygwin.com/ml/cygwin-announce/2012-04/msg00021.html

and

   http://cygwin.com/ml/cygwin-apps/2012-03/msg00246.html .

At least you can use cygwin do find out the default browser to launch

$ cat /proc/registry/HKEY_CURRENT_USER/Software/Classes/http/shell/open/command/@
"C:\Program Files\Mozilla Firefox\firefox.exe" -requestPending -osint -url "%1"
$

You can use this info to create a script that would launch the browser
with the argument
file:///C:/somepath/doc/ref/chap31.htm#X84F59A2687C62763

(note that you might need to rename the files from .html to .htm)

It should be doable, as at Windows command prompt the following works:

C:\>"C:\Program Files\Mozilla Firefox\firefox.exe"
file://C:/tmp/chap39.htm#X79C44528864044C5

HTH,
Dima
