VM for the transfer module - Application

Github repository: [1]

TODO list

• Research and experiment with the topics mentioned by my mentor:
  • implementation of UNIX wildcards.
• Define and implement some small tests for the compiler.
• Start generating the code from the transfer rules of the tests.

Weekly reports

(25/04 - 01/05): Basically this week has been dedicated to research/review some topics (some of them suggested by my mentor)

• I have been reviewing NLP and Python using 'Natural Language Processing with Python' book.
• I have been looking for a way to represent morphological labels in UCS/UTF and my mentor suggested using negative numbers as in Apertium internals. Anyway, I can worry about this later.
• Using UTF with Python: 'codecs' and 'unicodedata' can be some useful modules.
• Testing the option 'lt-proc' -b which is going to be the input of my compiler.

(02/05 - 08/05): This week I ended all the review/research needed, although I couldn't do all I wanted because I had to travel.

• Ended with the introductory book reviewing NLP and Python.
• Started designing and redefining the compiler's architecture following last year work and selected and did some tests with some modules. Some of the changes or improvements:
  • Use of pipes/command-line arguments for the input of the compiler (like the rest of Apertium).
  • Configurable logging module for info and debugging purposes (module: logging).
  • Refactoring some methods in the expatparser class (e.g. extracting common code of the callback method).
  • Create some additional classes in order to add some flexibility (e.g. parent class parser with the common code).

(09/05 - 15/05): This week I had to redo some work because of the Python3 switch, so didn't accomplish want I wanted. Anyway, two weeks of university classes remaining until I can focus exclusively in this project.

• Switched to Python 3, reasons:
  • I hope to get better UTF-8 support among other things.
  • Had to test if the modules I use were fully available/compatible in Python3.
  • Had to read and research (again...) about str/bytes and std{in,out}.buffer and, in general, everything related to Unicode, UTF-8...
• Started implementing the really basics of the compiler’s architecture:
  • Command-line arguments and help, input and output, logging...
• Another think I realized this week is that a lot of the thinking done last week about trying to make a flexible prototype so it is easy to modify in the future doesn’t really apply to Python. For example, my design involved creating interfaces/abstract classes in order to be able to easily change components, but that in Python isn’t needed. In conclusion: duck-typing, although I will need my design in the C++ version.

(16/05 - 29/05): This last days have been impossible with university work, just this week I had like 4 class projects and 2 exams... Tuesday next week I will finish everything and will be able to focus completely in my project.

(30/05 - 05/06): Finally I can focus completely in my project:

• Finish the structure of the project, now I am ready to start generating code from the transfer rules.
• Created the Github repository where I will submit my work (link is at the top).
