- Implemented support for parsing strings from files in various encodings.
Only string objects encoded in non-ASCII are supported, e.g., payee,
narrations, description, etc. This means the account names are still
restricted to ASCII, in particular. This works with UTF8 encoding
(tested),
latin1 encoding (tested), and probably more. The support is at the lexer
level. You may now supply an 'encoding' parameter to
parser.parse_file(),
parser.parse_string(), loader.load_file(), loader.load_string()
functions.
Passing in an invalid encoding should not mail it fail (though the
contents
of the strings will be empty). Unit tests for all those cases have been
added.
- Completely reviewed all lexer and grammar error handling code. The
parser
code used to bail out with abort() on an unhandled exception and dump
core
after issuing its error message (this is ugly but was never a big issue
since this occurred pretty rarely). All errors are now handled
gracefully
(invalid lexer token, exception raised in lexer builder, invalid grammar
rule, exception raised in grammar builder Python code). A comprehensive
suite of unit tests has been built to catch all these. You should never
experience a core dump anymore. A number of other unexpected cases has
also
been dealt with.
- The lexer used to have a fixed-size buffer for parsing its strings. The
buffer is now dynamically allocated. Lexing should also be slightly
faster.
- Memory management for the parser has been reviewed. Memory clean up for
temporaries generated during parsing has been reinstated (it was
disabled
somehow) and cleanup rules are invoked even in the case of errors. This
may
make the parser somewhat slower.

- Built support for setuptools and rolled back changes. Setuptools is
broken
beyond what I can bear. Forget this. You'll have to install
dependencies by
hand. It's a one-liner, like this:
pip3 install python-dateutil bottle ply lxml

- Wrote a post-mortem/assessment doc on LedgerHub, detailed future plans
for
LedgerHub and plans to eventually merge the codebase into Beancount
again.
