Aslak, in a step definition, is it possible for me to access the placeholder
name?
Given /^I type in "([^"]*)",$/ do |value|
    fill_in <placeholder_name>, :with => value
end
Here, the placeholder_name is also the name of the field I want to fill in.
I don't think I understand the question. You want Cucumber to guess
what text field you're typing into?

Thank you,

Aslak, in a step definition, is it possible for me to access the placeholder
name?

For example, in pseudo-code:

Given /^I type in "([^"]*)",$/ do |value|
fill_in <placeholder_name>, :with => value
end
Here, the placeholder_name is also the name of the field I want to fill in.

The placeholder names are the same as the field names, so there is no
need to guess if I can find a way to access the placeholder name.
Otherwise, I will have to type 20 nearly identical steps definitions.
Guess I'll get started now, and use your answer, if I can, another
time.

Hi Larry,

Do you mean the placeholder in a Scenario Outline step? If that's the
case, then you can write a step in your scenario outline like:

Given I fill in "<placeholder>" with "<value>"

which should use the values from the examples table for placeholder
and value, and match the Webrat step definition.

I'm not sure I made my goal clear. Let's say I have
Examples:
| first_name | last_name | ...
| Ichabod | Crane | ...
....

Let's also assume I have been careful to use the names of my form
inputs as the names of my placeholders. Then I would like to be able
to write something like this in my feature:

"And I type "<first_name>,...",

and then in my step def:

Given /^I type "([^\"]*)" ' do |value|
fill placeholder :with => value # expression 1
end

where the variable 'placeholder' would be assigned the value
'first_name' in the closure, or context in which expression (1) is
being evaluated. Instead I have to write:

'And I type "<first_name>" into field "first_name"'...

Then in the step def:

'Given /^I type "([^\"]*)" into field "([^\"]*)"/ do |value,
name| ...'

which works fine, but requires more typing, and thus has more
opportunity for error.

Just a suggestion for a future release.

   | first_name | last_name | ...
   | Ichabod     | Crane        | ...

I didn't understand from your first couple of emails that you were
using Scenario Outline and Examples tables. Now your question makes
more sense to me.
The term "placeholder name" isn't a term that conveys much contextual
meaning, although I know it's mentioned in the Scenario Outline wiki
page.

I suggest we use a different name for this. How about "Scenario
Outline parameter"?
Let's also assume I have been careful to use the names of my form
inputs as the names of my placeholders.  Then I would like to be able
"And I type "<first_name>,...",
Given /^I type "([^\"]*)" ' do |value|
   fill placeholder :with => value     # expression 1
end
What if I have something like this:

Scenario Outline: Eat veggies
Given I have <n> green <name> in my belly

Examples:
|n|name|
|7|potatoes|
|4|cukes|

And a step definition:

Given /I have (.*) green (.*) in my belly/ do |n, name|
# What would you expect the placeholder method to return in this case?
end

Aslak
where the variable 'placeholder' would be assigned the value
'first_name' in the closure, or context in which expression (1) is
'And I type "<first_name>" into field "first_name"'...
'Given /^I type "([^\"]*)" into field "([^\"]*)"/ do |value,
name| ...'
which works fine, but requires more typing, and thus has more
opportunity for error.

Aslak, FWIW, what if "placeholder" could be created as an array? Then
placeholder[0] == 'n', placeholder[1] == 'name'. Of course, I
understand that this would be only a convenience, although I'm sure
someone might find a more creative way to use this then to save me a
few keystrokes of typing. ;)

Sure! I'll be glad to.

I am newbie at Ruby, and have been looking for something to crack my teeth
on besides little step definitions, so maybe I'll take a shot at it myself
while I tried to find work to keep the wolf away from the door. It can't
hurt - I can only learn something. If I come up with something that works,
I'll submit a patch. Thanks much for your support.

I am newbie at Ruby, and have been looking for something to crack my teeth

I didn't understand from your first couple of emails that you were

The term "placeholder name" isn't a term that conveys much contextual

I suggest we use a different name for this. How about "Scenario

You need to bear in mind that there isn't a 1:1 mapping between
placeholders (or scenario outline parameters) used in in Scenario
Outlines and the regexp capture arguments that are passed to a step
definition.

For example, if there was very different behaviour for potatoes and
cukes in Aslak's example, you could equally implement those steps like
this:

Given /I have (.*) (.*) potatoes in my belly/ do |n, colour|
placeholder[1].should == "name" # surprise! you thought it would
return "colour", right?
end

Given /I have (.*) (.*) cukes in my belly/ do |n, colour|
end

I have a feeling that what you're asking for is built on the
assumption that placeholders:step args are always 1:1 - am I correct?
I think this feature could just exacerbate that confusion.

I think I understand your concern, but what I proposed to Aslak is
that the assignment would depend only on the appearance of
placeholders in the scenario outline step, such that "Given I have <n>
green <name> in my belly" would yield placeholders == ['n', 'name'].
It would have nothing to do with the regular expression or what it
captures.

   Given /I have (.*) (.*) potatoes in my belly/ do |n, colour|
     placeholder[1].should == "name" # surprise! you thought it would
return "colour", right?
   end
   Given /I have (.*) (.*) cukes in my belly/ do |n, colour|
   end
I have a feeling that what you're asking for is built on the
assumption that placeholders:step args are always 1:1 - am I correct?
I think this feature could just exacerbate that confusion.

Sure!  I'll be glad to.
I am newbie at Ruby, and have been looking for something to crack my teeth
on besides little step definitions, so maybe I'll take a shot at it myself
while I tried to find work to keep the wolf away from the door.  It can't
hurt - I can only learn something.  If I come up with something that works,
I'll submit a patch.  Thanks much for your support.

I didn't understand from your first couple of emails that you were
using Scenario Outline and Examples tables. Now your question makes
more sense to me.
The term "placeholder name" isn't a term that conveys much contextual
meaning, although I know it's mentioned in the Scenario Outline wiki
page.
I suggest we use a different name for this. How about "Scenario
Outline parameter"?
Let's also assume I have been careful to use the names of my form

I think I understand your concern, but what I proposed to Aslak is
that the assignment would depend only on the appearance of
placeholders in the scenario outline step, such that "Given I have <n>
green <name> in my belly" would yield placeholders == ['n', 'name'].
It would have nothing to do with the regular expression or what it
captures.
I was thinking the same thing Larry. Agree Matt?
Okay cool, I'm glad we all get that :)

Don't you think it would be quite weird that you'd end up building a
step definition that could only be used in a scenario outline though?
Seems to me that could make for brittle features.

I guess there's not really any harm in it but I do worry it has the
potential to confuse more people than it helps. Sorry if I sound like
a curmudgeon ;)

You need to bear in mind that there isn't a 1:1 mapping between
placeholders (or scenario outline parameters) used in in Scenario
Outlines and the regexp capture arguments that are passed to a step
definition.
For example, if there was very different behaviour for potatoes and
cukes in Aslak's example, you could equally implement those steps like
Given /I have (.*) (.*) potatoes in my belly/ do |n, colour|

Larry, would something like the following work?

Scenario Outline: Filling out a very picky registration form
...
When I fill in the following fields with:
| First Name | Last Name | Address | Country |
| <first_name> | <last_name> | <address> | <country> |
And I click 'submit'
Then the result should be <result>
....

Examples
| first_name | last_name | address | country | result |
| Greg | Hnatiuk | 23 st. | US | good |
| Someone | Else | 0 | nowhere | bad |

Given /^I fill out the following fields with:$/ do |table|
table.hashes.first.each do |k,v|
Given %Q{I fill in "#{k}" with "#{v}"}
end
end

I think I understand your concern, but what I proposed to Aslak is
that the assignment would depend only on the appearance of
placeholders in the scenario outline step, such that "Given I have <n>
green <name> in my belly" would yield placeholders == ['n', 'name'].
It would have nothing to do with the regular expression or what it
captures.
I was thinking the same thing Larry. Agree Matt?
Okay cool, I'm glad we all get that :)
Don't you think it would be quite weird that you'd end up building a
step definition that could only be used in a scenario outline though?
Seems to me that could make for brittle features.
Good point Matt

I guess there's not really any harm in it but I do worry it has the
potential to confuse more people than it helps. Sorry if I sound like
a curmudgeon ;)
Those are valid points. I think adding this feature would be
marginally useful and potentially confusing, so I'm not very keen on
it.
Cheers,
Aslak

You need to bear in mind that there isn't a 1:1 mapping between
placeholders (or scenario outline parameters) used in in Scenario
Outlines and the regexp capture arguments that are passed to a step
definition.
For example, if there was very different behaviour for potatoes and
cukes in Aslak's example, you could equally implement those steps like
Given /I have (.*) (.*) potatoes in my belly/ do |n, colour|
placeholder[1].should == "name" # surprise! you thought it would
return "colour", right?
end
Given /I have (.*) (.*) cukes in my belly/ do |n, colour|
end
I have a feeling that what you're asking for is built on the
assumption that placeholders:step args are always 1:1 - am I correct?
I think this feature could just exacerbate that confusion.

I didn't understand from your first couple of emails that you were
using Scenario Outline and Examples tables. Now your question makes
more sense to me.
The term "placeholder name" isn't a term that conveys much contextual
meaning, although I know it's mentioned in the Scenario
Outline
wiki
page.
I suggest we use a different name for this. How about "Scenario
Outline parameter"?

I didn't think of that, Matt. I'm a newbie so it didn't occur to me that
step definitions should not be so tightly coupled to the scenarios.

As for Gregory and Aslaks alternate solutions, I need to do a bit more
reading so that I can understand them fully. I haven't used those
constructs yet. Maybe if I had known about them I wouldn't have asked my
question in the first place.

I have to get back to some paying work now (what I originally wrote this to
test!), so I'm gonna have to let it go for now and move on. I appreciate
your responses.

Given /I have (.*) (.*) cukes in my belly/ do |n, colour|
end
I have a feeling that what you're asking for is built on the
assumption that placeholders:step args are always 1:1 - am I correct?
I think this feature could just exacerbate that confusion.

Sure! I'll be glad to.
I am newbie at Ruby, and have been looking for something to crack
my teeth
on besides little step definitions, so maybe I'll take a shot at
it
myself
while I tried to find work to keep the wolf away from the door.
It
can't
hurt - I can only learn something. If I come up with something
that works,
I'll submit a patch. Thanks much for your support.

Aslak, FWIW, what if "placeholder" could be created as an

Then
placeholder[0] == 'n', placeholder[1] == 'name'. Of course, I
understand that this would be only a convenience, although I'm sure
someone might find a more creative way to use this then to save
me a
few keystrokes of typing. ;)
placeholders # => return them all
placeholder # => alias for placeholders[0]
Could you please create a ticket for this in Lighthouse?

I'm not sure I made my goal clear. Let's say I have

I didn't understand from your first couple of emails that you
were
using Scenario Outline and Examples tables. Now your question
makes
more sense to me.
The term "placeholder name" isn't a term that conveys much
contextual
meaning, although I know it's mentioned in the Scenario
Outline
wiki
page.
I suggest we use a different name for this. How about "Scenario
Outline parameter"?

Let's also assume I have been careful to use the names of my
form
inputs as the names of my placeholders. Then I would like

where the variable 'placeholder' would be assigned the value
'first_name' in the closure, or context in which expression
(1) is
'And I type "<first_name>" into field "first_name"'...
'Given /^I type "([^\"]*)" into field "([^\"]*)"/ do |value,

which works fine, but requires more typing, and thus has

Hi Larry,
Do you mean the placeholder in a Scenario Outline step? If
that's
the

Given I fill in "<placeholder>" with "<value>"
which should use the values from the examples table for
placeholder
and value, and match the Webrat step definition.

Here, the placeholder_name is also the name of the
