Recursive Dependency size.

You should be able to work with just the base, use nc (netcat) in place of curl:

echo -e "HEAD $FILE HTTP/1.0\n" | nc $MIRROR 80

MIRROR being the host name (distro.ibiblio.org), and FILE the full path (/pub/linux/distributions/tinycorelinux/2.x/tcz/firefox.tcz)

curaga,
Very nice!  I have updated the script with your suggestion and it should now work with just the base Tiny Core. 

[curaga]

I hacked on the script some more:

Removed the temp file (var instead), used more shell builtins: ./depinfo.sh firefox.tcz is now 28% faster on a slow comp

edit:
I had turned spaces to tabs to save ~200 bytes and look better, but it looks worse pasted here..

Curaga,
Looks great!   Thanks for the improvements, I like your scripting style. 

Thanks again,
Brian

I have updated my original posting with an updated script.   It has Curaga's improvements and I also added in a couple of new features:

- Extensions that are already installed on your system will be green when listed.
- At the bottom, it will display the total size, how much of that is already installed, and how much would need to be downloaded if you installed the extension (example below)

Code: [Select]

           Total size (bytes)       35753984,  34.10 MB
    (Not currently installed)       27631616,  26.35 MB
          (Already installed)        8122368,   7.75 MB

Could you please attach the script file as well to the 1st post? Trouble is I am mostly at a windows terminal and copy-paste does not work, all the line feeds are a problem in Win.

Thanks!

- Extensions that are already installed on your system will be green when listed.

No green neither any other way to distinguish here...  (Total at bottom working as expected

Did you take out the "   . /etc/init.d/tc-functions" line of the script when you defined the MIRROR variable for Tiny Core 2.X?  Try putting back in the " . /etc/init.d/tc-functions" and see if the green color works then.

FIXED, Thank you 

getting close to apt-get in functionality, minus the bloat 

Suggestion: As the suffix ".tcz" is common to every package, would it be possible to eliminate the need to specify it on command line each time?

[curaga]

Let's get rid of the last sed as well

server=`echo $MIRROR | sed -e "s/http:\/\///g`

to

server=${MIRROR#http://}

getting close to apt-get in functionality, minus the bloat

Apt-get didn't have color IIRC, so we already surpass it.

That's a good idea.   I will modify the script so you can specify the extension with the .tcz extension or without it and get a new version posted tonight. 

I'll also get rid of that last sed line like Curaga suggested. 

Thanks,
Brian

This has been added in, you can now either specify the extension with .tcz or without.   Thanks for the suggestion.   I also replaced the last "sed" reference as Curaga suggested (thanks Curaga). 

I modified the original posting with the updated script.

The script seems to ignore the gtk2.tcz dep of MPlayer-svn-gtk2.tcz (in 2.x) while deptree.sh does pick it up.

Good catch.   There is a problem with the way it is determining if the extension is a duplicate.  I have a couple ideas on how to correct this and should be able to post a fix this afternoon when I have a few minutes to try it out. 

Thanks,
Brian

I updated my original post with a new version that fixes this issue.  Thanks for finding this bug.   The problem was with how it detected if the extension was a duplicate.

Thanks again,

When connection to server is less than ideal, it fails upon some single items in deps, e.g.

Code: [Select]

tc@box:~$ depinfo7.sh VBox-OSE
VBox-OSE.tcz                             size(bytes):   11202560,  10.68 MB
hal_support.tcz                          size(bytes):      40960,   0.04 MB
nc: bad address 'distro.ibiblio.org'
libcap.tcz                               Error, not found
libxslt.tcz                              size(bytes):     303104,   0.29 MB
libxml2.tcz                              size(bytes):     696320,   0.66 MB
nc: bad address 'distro.ibiblio.org'
libIDL.tcz                               Error, not found
SDL.tcz                                  size(bytes):     380928,   0.36 MB

Would there be any way to add something like more "grace time"?
