:host strategy cannot type strings with single quotes, but :preferences strategy can.

Related to Timeout when typing char that does not exist #605

Workaround

There is no satisfactory workaround. User's will encounter this problem when running tests against iOS 8 devices or when using the non-default :host strategy.

---

# :host - works
> keyboard_enter_text "wasn\\'t"
> keyboard_enter_text(escape_quotes("wasn't"))

# :preferences - results in an infinite loop
> keyboard_enter_text "wasn\\'t"
> keyboard_enter_text(escape_quotes("wasn't"))

---

In the short term, this kind of patch will work for most users.

string = "wasn't"
if ios8? and not simulator?
  text_to_type = escape_quotes(string)
else
  text_to_type = string
end
keyboard_enter_text text_to_type

---

Xcode 6.0.1, Xcode 6.1, Xcode 6.1.1

Using the develop branches of the toolchain: calabash-cucumber, run-loop, and calabash-ios-server.

Any iOS, simulator or device.

Reproduce

1. Launch an app with a text field from the console.
> start_test_server_in_background({:uia_strategy => :host})
2. Type a string with a single quote.
> keyboard_enter_text "Single ' in a string"

Expected

The string to be typed as "Single ' in a string".

Found

> keyboard_enter_text "Single \' in a string"
Sending UIA command
uia.typeString('Single \' in a string', '')
RuntimeError: uia action failed because: 
SyntaxError: Unexpected identifier 'string'. Expected ')' to end a argument list. 
eval@[native code]

Notes

String	Strategy	Result
wasn't	:host	Unexpected identifier 't'. Expected ')'
wasn't	:preferences	"wasn't"
wasn\'t	:host	Unexpected identifier 't'. Expected ')'
wasn\'t	:preferences	"wasn't"
wasn\\'t	:host	"wasn't"
wasn\\'t	:preferences	Timeout when typing char that does not exist #605

There is this documentation on the wiki [1] that recommends using escape_quotes [2]. That documentation was written before the :preferences route existed.

The escape_quotes is broken for the :preferences strategy; I will create a new issue for this.

This might be of interest to you since UITest uses the :host JavaScript.

With this pull request to run loop, calabash/run_loop#82, we get the following behavior (Note: tested on simulators so far, but devices shouldn't be different).

Ruby String	UIA Strategy	String entered on iOS keyboard
"karl's problem"	:host	karl's problem
"karl's problem"	:preferences	karl's problem
"karl's problem"	:shared_element	karl's problem
"karl's "problem""	:host	karl's "problem"
"karl's "problem""	:preferences	karl's "problem"
"karl's "problem""	:shared_element	karl's "problem" ***
"karl's \ problem"	:host	karl's \ problem
"karl's \ problem"	:preferences	karl's \ problem
"karl's \ problem"	:shared_element	karl's \ problem

*** UPDATED @jmoody + @john7doe "karl's problem" ==> "karl's "problem""

[krukow]

To me this is the most natural behavior

[krukow]

There is a new method used under the hood: escape_string (composing escape_quotes and escape_backslashes)

[krukow]

Should be fixed in 0.11.5.pre3 - #630

Please reopen if you see fit.
