* added new error signal no-nameserver-given
* modified send-receive-message-* functions:
- better error handling
- timeout/maxtries functionality
- try to contact all nameservers,
before error is signaled
Rename function TYPED-OPTONALS to OPTIONALS-FIRST and move its definition
to the only module that uses it: sxml.scm
Use LET-OPTIONALS instead of OPTIONALS, as it does the job, too, and
it ensures that the meaning of an argument depends only on its
position and not on the amount of arguments in front of it.
This commit removes a pitfall in calls to MAKE-TEXTAREA.
Nearly every example SUrflet continues to work unchanged, except of one
line in admin-surflets.scm, thus updating it.
descriptive and not misleading.
If you have written SUrflets that use the input field feature, you must
rename your input field commands to get them work with this change.
Contact me, if you want to have a small script that does this for you.
buttons return the coordinates where the user clicked à la
imgbtn321.x=13&imgbtn321.y=12. Thus, we cannot search for the
input-field-name of the image button. To remove this bug, we introduce
following changes:
surflet-input-fields.scm:
+ make-image-button returns a multi-input-field that searches for its
coordinates in the bindings, returning a pair (x y) of it (numbers).
+ Adapt select-input-fields to interface changes of multi-input-fields:
transformers get also their input-fields.
returned-via.scm:
Don't simply check for the input field name in the binding. Use
input-field-value to check for existance of the input field in the
bindings
input-fields.scm:
multi-input-fields get also their input-field as argument
web-server/root/surflets/byte-input.scm:
Adapt to interface change of multi-input-fields: transformers get also
their input-field
web-server/root/surflets/test.scm:
Check the image-button feature correctly.
+ Split input-fields into two structures:
+ surflets/my-input-fields allows you to create your own input-fields.
(complete with structure surflets/input-field-value)
+ surflets/surflet-input-fields are the proposals for input-fields
from SUrflets. They support annotated input-fields where
appropriate (select, radio, checkbox, hidden) and changing of attributes,
e.g. default values. See test.scm for examples.
The interface of the structure SURFLETS has only changed slightly
concerning the input fields
(make-higher-input-field --> make-multi-input-field should be the
main change)
+ Adapt examples to new input-field interface
+ Note new structures in documentation.
