Hello,
I am trying to use global variables, as pointed out at webgen FAQ
page, but no success. I am trying to put the following lines at
config.yaml file:
Core/Configuration:
customVars:
{myVar: This is really nice!}
I always get the error message:
> An error has occurred:
> Configuration invalid: No such configuration option: customVars
What am I missing here?
Is there another way to define global values (numbers, strings etc.)
and use them in lots of pages?
Thx for your attention.

From the example above, it seems that you are using webgen 0.4.x (and therefore the FAQ from http://webgen.rubyforge.org/documentation/0.4.x/documentation/howto.html). Note that there is an error in your example above: You need to indent customVars with two spaces: Core/Configuration: customVars: myVar: This is really nice The above should work. Best regards, Thomas
Hi Thomas, Thx for your response. I think I mixed up something here. Actually, I am using version 0.5.11 and used FAQ from version 0.4, sorry for my mistake. Anyway, is there a way to create global variables or a similar resource in version 0.5? My problem is: I have some values (integers and strings) which may eventually change with time, such that each time I recompile my website (using ''webgen'' command) they could be grabbed from global variables (or maybe from a data file) to be translated to html format. So every time they change, I can update just one place (config.yaml ou any other data file) and they will be changed in every page that uses them.

However, you have two possibilities: 1. Define the variables in ext/init.rb by storing them in a new configuration option: Webgen.website_access.config.globals({''mykey'' => ''value'', ''otherkey'' => 5}) Then you can access the values using the following ERB fragment in a page or template file: <%= context.website.config[''globals''][''mykey''] %> 2. Create a meta information file for storing each global variable on each page file that uses it: --- name:alcn **/*.html: mykey: value otherkey: 5 Then you can access the "global variables" in each such page file by using the meta tag: {mykey:} is something as well as {otherkey:} The second variant has the advantage that the page files are automatically regenerated when the values change. And the usage is similar to the one in 0.4.x. So I would try the second variant first! -- Thomas
Thank you again, Thomas!
The first suggestion you gave me is working but, as a matter of
fact, I observed that everytime I changed the values inside init.rb, I
had to manually "touch" the .page files in order to force their
recompilation by webgen, as you mentioned.
Just for the records, I had to replace the expression
Webgen.website_access.config.globals({...})
by
Webgen::WebsiteAccess.website.config.globals({...})
to make it work.
I put the second and preferred suggestion to work with no issues.
Everytime that I change values inside "metainfo" file, webgen
automagically recompiles all HTML files and updates those variables
inside the rendered page, as wished.
Best regards and congrats for your good work.
Paulo
