I would like the keyseq validator to be reviewed.
The diff file: https://gist.github.com/sahutd/0a471db8138383fd73b2#file-test-keyseq-diff
A sample test runner file:
In its current form, it supports/has
modifiers = ['Shift', 'Control', 'Alt', 'Meta']
alpha_uppercase = ['A']
alpha_lowercase = ['a']
direction = ['Up',]
direction_key = ['Key-Up']
It supports validating combinations upto 4 in length.
Please test for the above set only. (It will extended easily to fully
represent the respective complete sets. The reason it cant be done
*now* is the due to how RE optionals are coded differently in my
patch. See CLEANUP below). I will also add remaining keys like
Backspace, Slash etc tomorrow.
If we decide to go ahead with RE validating keys as in the above patch,
0. I made the mistake of not coding RE optionals -> ((pat)|(pat)) same
for all sets. The result is that, extending the current key set is not
possible without making all RE optional patterns similar.(Read the
starting lines of is_valid_keyseq method).
1. There is a lot of places where refactoring can be done and
appropriate comment added.
2. I left the asserts as-is. They can be used in testing the validator
3. The above patch still needs support for Backspace, slash etc to be
added. I decided to add, once I am sure we will use it.
4. I would like to know how it will affect Mac? What are system
specific differences? Please run the test-runner script on it and do
let me know.
My friend told that this thing can be done by "defining a grammar and
automata." I did read up about it, but found it hard to grasp
everything. Can you say whether it would be easier to solve it that
way than RE?
