Many people are asking to this plugin.
Can anyone with more UNIMARC knowlegdes than me start this?
I can improve the plugin later.

The script needs to be copied to ../intranet/cgi-bin/cataloguing/value_builder/
The template needs to be copied to ../intranet/htdocs/intranet-tmpl/prog/en/modules/cataloguing/value_builder/

I've tested and everything worked fine.

Vitor, looks promising, tested and works well AFAIK.

But:
1) You must make a patch
a) Verify unimarc_field_100_authorities.pl is chmoded +x

b) Update licence information, you do not work for katipo :)
read http://wiki.koha-community.org/wiki/Coding_Guidelines#Licence

c) do
git add cataloguing/value_builder/unimarc_field_100_authorities.pl
git add koha-tmpl/intranet-tmpl/prog/en/modules/cataloguing/value_builder/unimarc_field_100_authorities.tt
git commit -m "Bug 8334 - Authority UNIMARC 100 field plugin"

d) then do
git bz attach -e 8334 HEAD
or
git format-patch origin/master, and upload that as patch

2) But before upload, you must fix the following errors

3) Finally, you must add a test plan to the bug description, for example

a) Edit authority framework XXX, link subfield 'a' with plugin
b) create a new record or edit one
c) use plugin
d) save

4) Question: Is there a link to valid language codes? that could be a useful.

> d) then do
> git bz attach -e 8334 HEAD

Sorry, it's

  git bz attach 8334 HEAD

Hi Bernardo,

Sorry but at this point I can't do a patch for this.
If anyone could do that I'll be very appreciated.
Bernardo, thanks for testing it and give this info.

Vitor, 
If you do not mind, I'll post a patch on your behalf.

Bernardo

Thanks Bernardo for the patch :)

Patch applied cleanly, go forth and signoff

I lower a bit priority...

Looks good to me, I ask to Stéphane to have a look too.

Bernardo, could you confirm I can delete commented JS code in the tt file?

It works well, I sign off.

Bug 8334 - Authority UNIMARC 100 field plugin

The work for this patch belongs to Vitor Fernandez
Udated License information.

This patch adds a plugin for field 100 of UNIMARC
authorities.

To test on a UNIMARC site:
1) Apply the patch
2) Edit some authority framework, field 100
3) Link subfield 'a' to unimarc_field_100_authorities.pl
plugin, save
4) Edit or add auth record, clic on '...' to bring plugin
5) Modify field 100a
6) Save record

Please someone with UNIMARC experience take a look
at this.

Bug 8334: Remove commented JS code

> Bernardo, could you confirm I can delete commented JS code in the tt file?

I confirm :-)
That code was on the original file submited by Vitor, I suppose taken from a file he used as template.

Anyway, if this pass I think an update to UNIMARC frameworks will be needed to link this plugin permanently.

Bernardo

I've pushed this to master.  Thanks, Vitor!  And thanks, Bernardo, for rescuing this kitten.

I updated the author attribution in the base patch to use Vitor's name and credit Bernardo for converting it to a testable Git patch.

Patches pushed to 3.14.x, will be in 3.14.2
