Templates: various questions not worth their own thread

[ownedbycats]

Thanks

Any ideas why the second part of this template isn't removing the URIs?

program:
	publisher = $publisher;
	ids = $identifiers;
	u = select(ids, 'uri');
	g = select(ids, 'gutenberg');

	if publisher == 'Project Gutenberg' && u != g then
		n = re(u, '^http://www.gutenberg.org/(\d+)', '\1');
		ids = list_union(ids, strcat('gutenberg:', n), ',')
	fi;

	if publisher == 'Project Gutenberg' && u && g then
		ids = list_difference(ids, strcat('uri:', u), ',')
	fi;
	ids

program:
	publisher = $publisher;
	ids = $identifiers;
	u = select(ids, 'uri');
	g = select(ids, 'gutenberg');

	if publisher == 'Project Gutenberg' && u != g then
		n = re(u, '^http://www.gutenberg.org/(\d+)', '\1');
		ids = list_union(ids, strcat('gutenberg:', n), ',')
	fi;

	if publisher == 'Project Gutenberg' && u && g then
		ids = list_difference(ids, strcat('uri:', u), ',')
	fi;
	ids

Are you certain that the conditions in the second 'if' are all True, that both 'ids' are set when the template starts? Run it using breakpoints to check (and record) the values.

Also, both conditions check for "publisher == 'Project Gutenberg'". You could test that once and put the other tests as nested ifs.

Actually I think it's a mistake of what I thought template tester was doing; I was testing with books that only had uri. If I add gutenberg: and test again it removes the uri: identifier.

Also, preferably I would just skip the Publisher and check for a uri: contains http://www.gutenberg.org/ but I'm not sure how to do that.

Something like this should work:

if '^http://www.gutenberg.org/' in u then 'foo' fi

@chaley: Running the following template returns true i.e "1"

program:
	'' inlist 'first,second'

Is this intentional?

Yes. It uses python regex where a zero-length pattern matches any string.

It isn't clear to me what the expression is looking for. If you looking for an empty list then there are several ways to do that, such as a == '' or list_count() == 0. If you are looking for an item in a list then you must explicitly decide what happens if the item is empty. Does it match, or does it fail? If you know you want the left-hand expression to match *something* then you can use

substr('^', value, '$') inlist whatever

or perhaps clearer, str_in_list()

[capink]

I think str_in_list() is a good answer.

I was using it in action chains conditions where some variables can return empty values, so I had to nest the value in if statment to make sure it is not an empty string:

program:
	clicked_column = list_item(globals(_event_args), 1, ',');
	if clicked_column then
		if clicked_column inlist field_names('is_multiple:true,is_names:false') then
			'true'
		fi
	fi

Turns out there are other problems with the above code that I did not take into consideration: if variable is not anchored, #my_custom_col passes for #my_custom_col_1

Edit: The below code is working well

program:
	clicked_column = list_item(globals(_event_args), 1, ',');
	tag_like = field_names('is_multiple:true,is_names:false');
	str_in_list(tag_like, ',', clicked_column, 'true', '')

To work around another FanFicFare issue, I want to make a template that removes either 'In-Progress' or 'Complete' from tags if #fanficstatus is 'Anthology.'

program:
	status = $#fanficstatus;
	tags = $tags;
	
	if 
		status == 'Anthology'
	then
		tags = list_difference(tags, strcat('In-Progress', 'Complete'), ',')		
	else
		tags
	fi

This just returned the original list. Should I have used something other than list_difference?

[capink]

Try this:

program:
	status = $#fanficstatus;
	tags = $tags;
	
	if 
		status == 'Anthology'
	then
		tags = list_difference(tags, 'In-Progress,Complete', ',')		
	else
		tags
	fi

The problem in your code was this line:

strcat('In-Progress', 'Complete')

which returns a new string that is not present in your tags

In-ProgressComplete

Edit: strcat() is only needed if you are concatenating variables. If all you are using is plain text you can still use strcat(), but you do not need to.

That S&R doesn't do anything. Templates are not evaluated as search expressions; they are interpreted as plain text. A template is evaluated only if you use "Template" as the source field, and then only if you put it in the "Template" box.

The replacement of /1 is also plain text. I suspect you wanted \1.

What are you trying to do?

I accidentally wiped out my Audit Log while troubleshooting plugins so I was copying the column to itself so that AL had a record of the original values. I figured out what I had to do though.

It works by accident.

Searching for /1 finds nothing because that character sequence doesn't exist in an ISO date. Replacing with /1 would replace with exactly that text, /1, but since nothing was found, nothing was replaced.

You probably wanted search for ^(.*)$ and replace with \1. This matches the entire source and replaces it with itself
