[Zope-dev] Traceback
How hard would it be to add more of the called URL to the traceback? Background: I have been developing relatively baroque SQL sites for internal use and find that when I am making changes to facilitate re-use higher up in the hierarchy, it can be relatively difficult to find out what failed.

I know, there are docs explaining acquisition and object publishing has an implicit meaning. Things like 'Specialist' and 'DataSkin' don't have implicit enough meaning unless you're on the 'inside' of ZPatterns... Also, as in the early days of Zope, terminology evolves and changes as the developers of the concepts seek better ways to explain them to other people. Hmm, unlike the early days of Zope, would you mind documenting these changes so we have more to 'grab hold of'? ;-) snip where 'specialist' came from Perhaps a set of 'glossary' wiki pages? These would have the name of the object/class/type/word/whatever with links to what it used to be called as well as to documentation abotu what it currently is and if it's been outdated, what it's called now (and why its name changed).

SteveA, you seem to get all this stuff? could you knock something up for Ty and Phil to 'fill in'? snip things are becoming simpler I think I see that now, but if the wiki was kept up to date by the people who understand it best, Ty Phil ;-), then the rest of us might have a chance of keeping up :-) Unfortunately, all this evolution makes ZPatterns a moving target for comprehension at the moment. In spite of this, my reading of the lists seems to indicate that there are a few people besides Ty and myself who are actually achieving results with the framework. I've noticed this too, and it's very cool :-)) I hope that they can help to provide more accessible how-to materials, Someone must have money for this? (sadly not me...

Naming has been a struggle. It's hard to come up with descriptive names
for these things. Part of the confusion is that some things have been
renamed in an effort to make the meanings clearer in the long term. But
short term, it's confusing and it seems like there are lots of new
concepts, when in fact there are just several names for the same concept
(Implementor - Specialist, Rack-mountable - DataSkin, etc).
I know, hence the glossary suggestion :-)
I'll also
admit that Rack-mountable was a clearer name, but it was no longer
accurate. We tend to err on the side of a name that doesn't clearly
describe something instead of a name that clearly describes something,
but describes it *wrong* so that you think you understand something and
really don't. ("Well, at least the name tells you that you don't know

Fair enough, but then they really need to be explained for us mortals...
You mention in another post that you feel lots of unnecessary features
have been added -- can you give some examples of which ones you feel are
extraneous?
Probably me just misreadign the new terms popping up all the time :-)
There has been only one major feature added in ZPatterns
0.4.0, which is the ability to have Rack-mountable-like things that
don't live in racks. This is important for PTK-like applications where
you don't want to lump everything into one container, but would instead
like to have it distributed between member's folders, for example. I
think it was worth it.
So do I, I just didn't understand it ;-)
The PlugIns stuff is indeed separate, and is not really a part of
ZPatterns as much as it's stuff that we wrote to make ZPatterns and
other Zope products easier to write.
Maybe split it into a seperate product then? It might make learning
ZPatterns easier since this area won't get dragged into it...
You can pretty much ignore it if
you won't be writing python products or working in ZPatterns internals.
I will on the first count, hence the interest. Squishdot PTK is looming
ever closer now...
0.3.0 is pretty stable, I think. 0.4.0 alphas have been buggy. But they
*are* alphas, after all. You were warned :^)
Any idea on a beta or final release schedule?
What, you want something that's *not* based on any theory, just random
ideas? :^)
No, but maybe the percieved pretentiousness upsets some people?
As someone who used Zope for quite a while before it was

I'm guessing I have a pretty good idea of how you feel. I've gained a
new sympathy for DC.

and it's hard to find time right now to work on things in
ZPatterns that don't directly affect our paid work. (Much the same
situation DC is in a lot of the time, I suspect).

I feel the Zope world (and others, most likely) could benefit from a 'preferential' redirector. The way I would do this is have section1.contrived-example.com section2.contrived-example.com section3.contrived-example.com with siteAccess, and then each zope would serve it according to it's IP (though each "could" serve each site). Then you can use whatever IP/DNS load balancing tool your heart desires. I think most people seem to be missing the point here. The idea is that ALL servers can serve ALL content. HOWEVER, the 'load balancer' will opt for a certain server for a certain URL, in order to improve cache hits. So, for www.contrived-example.com/dir1 it will first try server1, but if it's busy (or down) it will try others. This way, the cache on server1 is more likely to contain objects relevant to /dir1 and thus have a higher hit rate, therefore improving performance. No, I understand what is being discussed, I doubt the problem. :-) Given an equal distribution*, then all the back-end (BE) servers will have a fairly consistent cache content from server to server. you are _equally_ likely to hit a server with that object in cache. The more requests you have for a given object, the greater odds you'll see it in the caches of all BE servers. * Now, not all systems are equal, this is true. However, in an intelligent load balancing sysstem, you 'weight' the faster/better performing machines, such that they are hit more often. Since these machines will be used more frequently, they will have the best chance to have what you want in cache already. I just don't see that the additional effort is worth it. The job is already done, and the additional overhead would seem to outweigh any perceived increases in performance. See below. An enforced 'mapping', as you were suggesting, removes ALL redundancy from the site, but would likely provide even better cache hits. How so? http://my.site.com/sec1 is mapped to: sec1.site.com, which is load balanced across as many machines as possible, using ZEO and a load balancing tool. Any of the machines in the pool known as sec1 (nobody said it had to be a single machine) could respond. since these machines serve out sec1 predominantly (they can also participate in the general site load balanceing servers), these would have a better cache hit rate on sec1 stuff than the primary BE servers. Perhaps this can help: www.libc.org (real site, fictional setup :) is a ZEO cluster. o The site's primary ZEO Clients number 5. o My load balancing tool lets me weight some servers over others. /Members is a heavily trafficked section, so I want it to be seperated out using a rewrite tool (SiteAccess, Roxen, Apache mod_rewrite, whatever) to send all /Members urls to members.libc.org. I set up two ZEO clients, M1 and M2. These two talk to the same ZSS as the other 5, and respond to members.libc.org. So, when you go to www.libc.org/Members, you will wind up on either M1 or M2. These machines are set up as low-weighted primary site servers (bringing the total up to 7), so they will have a cache that is biased towards /Members, but still can serve up any part of www.libc.org If M1 or M2 goes down, you stay up. For added redundancy, you can add the other 5 primary servers as low-weighted servers for members.libc.org, such that if both M1 and M2 die, or get heavily loaded, one or more of the other 5 can pick up the overage, just as M1 and M2 can for teh 5 primary servewrs for the main site. Now you have 'preferred' machines, to improve cache-hit-rate for certain heavily trafficked sections of your site, and maintain (or even improve) overall performance and redundancy of the system. Of course, you still have ZSS as a SPOF, but even that can be gotten around with good design and planning. :^) If that isn't enough, you can throw eddieware into the mix, which *already* has the ability to redirect based upon the URL.

It does however make it pretty easy to get things going fairly cheaply. There is a trade off between resuable phrase lengths and making phrases unambiguous that you have to deal with. If it breaks, you get to keep both bits. Readme Excerpt: This is the ZBabel Translation System for ZOPE, the Z Object Publishing Environment (http://www.zope.org/) This is a phrase by phrase translation system, it allows you to translate key parts of your site, and the content if you desire. With this you don't need to maintain seperate source for each supported language, or mix different languages in your source. You can do your entire site in one language and then translate it without re-editing the source code. This system also automatically creates the catalogs as you go, you do not need to manually insert text strings into databases for translation. ZBabel comes as a two part kit, to help you with translating your ZOPE Content. The first part is the tag dtml-babel which allows you to register and translate your phrases. The second part is a the ZBabel Tower Product. This is a Folderish Object that does most of the legwork. You will need a ZBabel Tower Product installed somewhere that your documents can acquire it if you want translations to occur. If you do not install the product, the dtml-babel tag will simply return the existing text. -- Totally Holistic Enterprises Internet| P:+61 7 3870 0066 | Andrew Milton The Internet (Aust) Pty Ltd | F:+61 7 3870 4477 | ACN: 082 081 472 ABN: 83 082 081 472 | M:+61 416 022 411 | Carpe Daemon PO Box 837 Indooroopilly QLD 4068|[EMAIL PROTECTED]| ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
[Zope] how to make an Product executable

RE: [Zope] how to make an Product executable
I have a question ..
I create a product and i would like to to use my product when I select
it from the objects combo box. But It always puts me into the security
screen !!! and not my index_html. I have several methods in that product
..
To create a new object you must supply an addForm and a method to add the
product.
e.g.
manage_addMyProductForm = HTMLFile('MyProductAdd',globals())
def manage_addMyProduct(self, id, title='')
"""Adds the product"""
self.setObject(id, MyProduct(id,title))
if REQUEST is not None:
return self.manage_main(self, REQUEST)
The product tabs are defined in the manage_options section of the product.py
The order is important the first item in the list is called when you access
the object from the management screens. The index_html is the default when
accessed without the management screens.
For example:
manage_options = ( # the management options available
{'label': 'Contents', 'action': 'manage_main'},
{'label': 'View', 'action': ''}, # defaults to index_html
{'label': 'Properties', 'action': 'manage_propertiesForm'},
{'label': 'Security', 'action': 'manage_access'},
)
Download the boring product from zope.org
It is a plain shell of an object that does nothing, but works.
Hope that helps

[Zope] Apache+mod_SSL+FastCGI+ZServer
I am fairly new to zope and evaluating its use for a medium traffic commercial site where security is a requirement. After reading through a lot of opinions and info on the zope site (http://www.zope.org), I came to the conclusion that to get scalability and security, Apache + mod_SSL + FastCGI + ZServer was the way to go. There was also mention of a zope product (called MX-Crypto?) which allowed SSL with ZServer without requiring Apache, but it looked to me to be in early development (I did not look at this closely). I set up the mod_SSL + FastCGI, etc and tried it out. Details on the installation, problems encountered, etc may be found in http://www.zope.org/Members/jasperh/SSL_FastCGI_setup In particular, I had trouble getting the zope management screens to work when SSL was compiled in. Any comments as to whether the Apache+mod_SSL+FastCGI+ZServer idea is good, bad or ugly for the intended use would be much appreciated. jasper (jasperh at mweb dot co dot za) ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
RE: [Zope] Announce: ZBabel a Translation Assistant for Zope
Thanks for "ZBabel". I've only just downloaded it and haven't played with it yet, but from just reading through, it looks like it will be a great approach! http://www.zope.org/Members/TheJester/ZBabel/ One thing I'm not clear on, which you might want to deal with in future releases, either by documenting what wasn't obvious to me, or by adding a separate layer, is how to deal with "Composite Strings". Often a "phrase" that will need translation is a concatenation of more than one text string with embedded dynamically generated parameters, such as a date, name, price etc. In different languages the actual ordering of the concatenated elements may differ and the structure of the destination language may even result in a different number of text strings to translate than for the source language. Often the original author of a dynamically generated web page will be tempted to use a repeated string for common parts of different UI strings, which cannot in fact be translated that way for other languages. Unless there is some provision for that in the management interface for translation, and the documentation, page authors are very likely to assume they have internationalized something when they haven't, because they may concatenate ZBabelized strings themselves. See for example: http://msdn.microsoft.com/library/default.asp?URL=/library/books/techlang/de vintl/D3/S24AA.HTM I would imagine that Zope is ideally suited to using some sort of class for each composite, with properties for the phrase identifier and the constituent dynamically generated parameters, and leaving it to the specific translation to determine the number and positioning of the elements required. Is that already taken into account somehow by allowing the embedding of DTML within the text phrase to be translated? Also worth thinking about for a future release, is the integration of this with layout considerations. Other languages often require 50% more space than english when translated and this results in layout problems after translation. Reasonably precise formulae are available for what to expect, depending on the length of the string and the source and destination languages. I would imagine that Zope would also be ideal for automatically generating the maximum of this for the acquired set of expected future translations and returning it as a parameter that could be used with dynamic layout. Finally, is there some way that the "magic" behind Zwicki structured text formatting could be used, to allow an author to just write the phrase in their own language and automatically generate related DTML tags for parameters etc? (Rather vague idea I know, but somehow make it easier for people just writing content, like Zwiki contributors, to know nothing about DTML at all, yet still make it easier for scripters to integrate their translatable content with DTML as well as integrating with HTML layout). ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

This way, the cache on server1 is more likely to contain objects relevant to /dir1 and thus have a higher hit rate, therefore improving performance. No, I understand what is being discussed, I doubt the problem. :-) You are right, theres no problem in the scenario you described. Ill fill in some more details about the fictional example for which I still can't see an easy solution Zope is used to store books. Each book object contains: 1. The text of the books, each page in a separate object 2. Images and diagrams for the book. 3. A ZCatalog full-text-index of the book. Each book object allows: 1. Searching, viewing pages, etc. 2. Dynamically rendering a range of pages as pdf, postscript, etc. The whole database stores 10,000 books, and is served by a cluster of many identical Zope servers. A typical usage pattern might be: a. Users searches through a book to find the interesting pages b. He browses the pdf version of those pages c. He tweaks the page range, and double-checks the pdf version. d. then downloads a postscript version of that page range for printing Assume that noone has accessed this book recently, so it's not in any caches. The cache has to be filled at step b. This transfers alot of data - possibly the whole content of the book - and introduces a noticeable delay. The possibility for optimisation comes at steps c and d. There is one cache already filled with the right data - if the requests from c and d can be directed to the same server as the original then the cache-filling delay can be avoided. This extra delay might not have a great impact of actual site performance, but I've found a catastrophic affect on perceived performance in some usability tests. Users seem happy to accept a delay when they first access their data, but not if it repeated in a subsequent request.

Hi Mario,
In reference to your problem where GUF cannot access "real_password", try

where I could access my sql methods, but could not access the results from

Let me know how it goes and if you have any questions.

RE: [Zope] Announce: ZBabel a Translation Assistant for Zope
[Andrew]
Yes you can embed DTML inside the block and it will resolve all of the
DTML before translating the result. You can turn this behaviour off.
This is why I opted for a container tag, rather than a simple tag.
[Albert]
That is what I am still not clear on. Noticed the container, but still
confused about "literal" and about "before", "after", "off" and "on".
Suppose web site in source language has something like this:
'Click A href="{fieldX(someVar.A)}"here/A, for {fieldY(someVar.B)}'
With suitably horrific DTML instead of ' ' and {}.
Rendered english result would be, for some particular dynamic instance of
someVar:
'Click A href="http://www.zope.org/"here/A for Zope'
Translator for language X decides to reverse the positions of fieldA and
fieldB and use 3 separate substrings, because it is too abrupt for that
language, so translates to something like:
'If you would like {fieldY(someVar.B)}, click A
href="{fieldX(someVar.A)}"this link/A, please'
There are now 3 substrings in the translation because it would be rude not
to start or end with something like "please" in language X, and it reads
better with the fields reversed in that language.
Final rendered result becomes (in language X):
'If you would like Zope, click A href="http://www.zope.org/"this link/A,
please'
depending on the particular value of someVar at the time.
Does ZBabel allow this? If so, that's *exactly* what I was hoping for.
(Naturally it is up to the classes for fieldY and fieldX to do their own
thing, and localize it if its a date or currency etc, not up to ZBabel).

[Andrew]
I have another project on my TO DO list which is a dynamic components
product which this would integrate well with.
Any "Form Generation" products would probably be able to integrate
the same stuff as well fairly easily.
It is rather intrusive I know, but, there are few if any options that
don't require massive amounts of effort to achieve the same thing.
Especially building the catalogs. I know of another ASP based system
that's pretty much the same as this, but, they have to go through
and change the source code after translating (they have to provide a
dummy 'phrase id' which is then altered). It is really really ugly.
[Albert]
The lack of a dummy "phrase id" is what I thought was really great about
your approach. Thanks!
I regard HTML/DTML as possibly avoidable clutter in the same way that a
"phrase id" is.
If ZBabel already does what I asked above, my question about something
closer to Zwiki structured text might be more clear in terms of wondering
whether anything can be done to hide the HTML/DTML tagging and field coding
from the translator by giving them some sort of template like this:
'Click [here] for {Zope}'
So that they would translate it to:
'If you would like {Zope} click [this link[here]], please'
Note that the two original substrings of ordinary text AND the [bracketed]
text all denote elements to be translated, while the text in {braces} does
not, but is sample data visible in the UI as a prototype example for the
translator.
Then the magic which extracted the HTML (and DTML) tagging and field names
etc to give the translator something more understandable, would just stick
it back in, replacing "here" with "this link", but ALSO restoring the
surrounding DTML/HTML for that element and for the {Zope} element, in much
the same way that you already do not need a "phrase id" but work directly
with the text. Translators understand prototypes much more easily than they
understand web pages.
(Also useful for content managers cf HTML/DTML designers and convenient for
HTML/DTML designers too ;-).
Any possibility of doing that automatically? By clicking "generate
template", a web developer might be able to generate simplified template
strings like above for the translator, using a sample prototype from actual
data. Then, when the translator has processed it, a web developer or content
manager could just click "import translation".
Otherwise either the web developer might still need to generate such
prototypes manually to make life easier for translators, or the translators
need to understand some HTML/DTML as well as understanding translation.
Seeya, Albert

Hi,
Are you searching for the exact word "Plays", or is there a
variable called Plays against which you are trying to match
a value? If it's the latter, having the single quotes is
teling it to search for the literal. If you are setting the
value of plays in a higher call, eg. dtml-call
"REQUEST.set('Plays', Play_titles)", your if expression
would need to be "which_table == Plays".
Hope this is helpful, as it is a mistake I am always making!

Paul Browning wrote: OK, this is true of most things (computer languages, foreign languages, mental arithmetic, parenthood, etc) - if you don't use it, you lose it. But there is something about DTML that distinguishes it (for me) from other languages - it's the rate at which it decays on you. Python's decay constant is much more favourable. I think this would be a very useful metric to measure how effective any improvements to DTML are, can you stick it in the relevent wiki somewhere? So I've learned a rule of thumb - if I'm writing DTML and it isn't flowing then I really ought to be using Python. This isn't always true IMHO... PythonMethods are nice but, as they stand, you only have access to built-in functions. So if you want to import modules you have to resort to External Methods. [Am I talking nonsense here? My empirical experience is that I can use string functions in a PythonMethod but not, say, stuff from the time module. Neither string nor time are built-in though . so why one and not the other?] I hope you're talking nonsense ;-) The point of these reflections: * PythonMethods ought to be a high priority IMHO. Very much so... * DTML is holding Zope back for the rest of us (and is arguably a "proprietary" component of Zope (in that you can't use it anywhere else) - this is a disincentive to many power-Perl,JSP,name-your-scripting-poison users I suspect. I think all these scripting poisions are proprietery and will remain so in that sense. The sad fact is that DTML ranks amoung the worst of them right now, IMVHO... * Please can we import Python modules from PythonMethods (or can we already and I don't about it, or does this break the sandbox that PythonMethods is meant to provide)?

The idea is that ALL servers can serve ALL content. HOWEVER, the 'load balancer' will opt for a certain server for a certain URL, in order to improve cache hits.

This way, the cache on server1 is more likely to contain objects relevant to /dir1 and thus have a higher hit rate, therefore improving performance. No, I understand what is being discussed, I doubt the problem. :-) You are right, theres no problem in the scenario you described. Ill fill in some more details about the fictional example for which I still can't see an easy solution Zope is used to store books. Each book object contains: 1. The text of the books, each page in a separate object 2. Images and diagrams for the book. 3. A ZCatalog full-text-index of the book. Each book object allows: 1. Searching, viewing pages, etc. 2. Dynamically rendering a range of pages as pdf, postscript, etc. The whole database stores 10,000 books, and is served by a cluster of many identical Zope servers. A typical usage pattern might be: a. Users searches through a book to find the interesting pages b. He browses the pdf version of those pages c. He tweaks the page range, and double-checks the pdf version. d. then downloads a postscript version of that page range for printing Assume that noone has accessed this book recently, so it's not in any caches. The cache has to be filled at step b. This transfers alot of data - possibly the whole content of the book - and introduces a noticeable delay. The possibility for optimisation comes at steps c and d. There is one cache already filled with the right data - if the requests from c and d can be directed to the same server as the original then the cache-filling delay can be avoided. This extra delay might not have a great impact of actual site performance, but I've found a catastrophic affect on perceived performance in some usability tests. Users seem happy to accept a delay when they first access their data, but not if it repeated in a subsequent request. Bill wrote... http://my.site.com/sec1 is mapped to: sec1.site.com, which is load balanced across as many machines as possible I might be reading more into his words than was intended, but I think this demonstrates the problem. Distributing multiple requests for one section across multiple servers is (what I consider to be) undesirable. You can actually do it either way. Curtis (AIUI) complained that the method described meant your site depended upon each of th esection's servers being up, that there was no redundancy. So I described a way of doing it with redundancy. I want to move load balancing up one level of abstraction - distributing sections across machines (rather than connections). That's easier :) Make sec1.site.com a single machine, and all requests for my.site.com/sec1 go to this machine, thus the cache will have it loaded if it has been accessed at all. The downside, like Curtis mentioned, is that if sec1 dies, you lose that part of the site. If that isn't enough, you can throw eddieware into the mix, which *already* has the ability to redirect based upon the URL. Ive not seen eddieware before - so it looks like Ive got some reading to do. At a first glance it doesn't have any integrated http caching (although it seems to have everything else ;-) and theres no obvious place to hang squid. In my example above, I really want to be able to cache the rendered pdf files. EddieWare does do 'intellgient' caching, allowing you to seperate out sections of a site to a server (for example, all images come from this machine, and text from that one, etc.), and it works at the IP Address level.

[Zope] ZCatalog Reindex_object Problems
Hi,
I've been struggling trying to get the catalog to index catalog
aware objects. There are several messages from people with similar
problems, in the archives, but none of the solutions seem to work. I have
created a Product with a catalog aware class called Job_Request. The
Product also has a Job_Request_addForm method and a Job_Request_add
method. The form simply asks for user input for various fields and the
Job_Request_add method is meant to create the class instance, set the
properties, and index the object. In order to test the class I made an
object which lists all items the catalog as well as allows me to search on
a single field. The problem seems to be that the catalog will not update
after I Input a value that the catalog has not yet seen for a particular
field. Some Examples:
1. The catalog already has a Job_Request object with the
agency_name property set to NASA. If I add another object to the catalog
with agency_name = 'NASA', the result lists for an unrestricted search and
a search restricted to NASA both contain the correct record.
2. I delete all objects where agency_name ='NASA' and then I add
a new one with the same agency_name, I get the same results as above.
3. I add a new Job_Request where the value of agency_name is one
that has yet to have been cataloged i.e. agency_name =
'NeverHadThisValue', and the results for an unrestricted search on
agency_name shows the record, but the results restricted by agency_name =
'NeverHadThisValue' comes up empty.
Any help on this would be greatly appreciated (Is it a bug? If so
what's the best workaround)

HOWEVER, the 'load balancer' will opt for a certain server for a certain URL, in order to improve cache hits. Because you're using SiteAccess, every node can access the objects that the subdomain-primary serves, so you can do loadbalancing or failover.

| [Andrew]
| Yes you can embed DTML inside the block and it will resolve all of the
| DTML before translating the result. You can turn this behaviour off.
| This is why I opted for a container tag, rather than a simple tag.
|
| [Albert]
| That is what I am still not clear on. Noticed the container, but still
| confused about "literal" and about "before", "after", "off" and "on".
|
| Suppose web site in source language has something like this:
|
| 'Click A href="{fieldX(someVar.A)}"here/A, for {fieldY(someVar.B)}'
|
| With suitably horrific DTML instead of ' ' and {}.
|
| Rendered english result would be, for some particular dynamic instance of
| someVar:
|
| 'Click A href="http://www.zope.org/"here/A for Zope'
|
| Translator for language X decides to reverse the positions of fieldA and
| fieldB and use 3 separate substrings, because it is too abrupt for that
| language, so translates to something like:
|
| 'If you would like {fieldY(someVar.B)}, click A
| href="{fieldX(someVar.A)}"this link/A, please'
Aha! This is not translation d8) This is re-wording and then translating,
which is a bit of fine hair splitting I know. If you reached a point
where something couldn't be translated, you would have to revisit the source.
| There are now 3 substrings in the translation because it would be rude not
| to start or end with something like "please" in language X, and it reads
| better with the fields reversed in that language.
|
| Final rendered result becomes (in language X):
|
| 'If you would like Zope, click A href="http://www.zope.org/"this link/A,
| please'
|
| depending on the particular value of someVar at the time.
|
| Does ZBabel allow this? If so, that's *exactly* what I was hoping for.
I think it does what you want to do...
dtml-babel src="langA" dst="langX"dtml-var GreetAndLink/dtml-babel
GreetAndLink...
Click a href="dtml-langXUrl;" For dtml-var AJollyRogering
You would end up with the following to be translated:-
Click a href="the.langx.url" For a good langX clicking
So you would end up with a phrase that would be partially
translated ready for translating because your langXUrl and
AJollyRogering already do some localisation.
However if langXUrl and AJollyRogering are dynamic you should probably
not wrap them in dtml-babel tags.
| [Andrew]
| I have another project on my TO DO list which is a dynamic components
| product which this would integrate well with.
|
| Any "Form Generation" products would probably be able to integrate
| the same stuff as well fairly easily.
|
| It is rather intrusive I know, but, there are few if any options that
| don't require massive amounts of effort to achieve the same thing.
| Especially building the catalogs. I know of another ASP based system
| that's pretty much the same as this, but, they have to go through
| and change the source code after translating (they have to provide a
| dummy 'phrase id' which is then altered). It is really really ugly.
|
| [Albert]
| The lack of a dummy "phrase id" is what I thought was really great about
| your approach. Thanks!
|
| I regard HTML/DTML as possibly avoidable clutter in the same way that a
| "phrase id" is.
|
| If ZBabel already does what I asked above, my question about something
| closer to Zwiki structured text might be more clear in terms of wondering
| whether anything can be done to hide the HTML/DTML tagging and field coding
| from the translator by giving them some sort of template like this:
|
| 'Click [here] for {Zope}'
|
| So that they would translate it to:
|
| 'If you would like {Zope} click [this link[here]], please'
|
| Note that the two original substrings of ordinary text AND the [bracketed]
| text all denote elements to be translated, while the text in {braces} does
| not, but is sample data visible in the UI as a prototype example for the
| translator.
You can do this by nesting dtml-babel calls...
dtml-babeldtml-babelClick here/dtml-babel dtml-babelfor
Zope/dtml-babel/dtml-babel
Would yield the following to be translated:-
o Click here
o for Zope
o Click here for Zope
| Then the magic which extracted the HTML (and DTML) tagging and field names
| etc to give the translator something more understandable, would just stick
| it back in, replacing "here" with "this link", but ALSO restoring the
| surrounding DTML/HTML for that element and for the {Zope} element, in much
| the same way that you already do not need a "phrase id" but work directly
| with the text. Translators understand prototypes much more easily than they
| understand web pages.
|
| (Also useful for content managers cf HTML/DTML designers and convenient for
| HTML/DTML designers too ;-).
|
| Any possibility of doing that automatically? By clicking "generate
| template", a web developer might be able to generate simplified template
