[Gnumed-devel] phrase wheel

[Karsten Hilbert]

Richard,

I have started working on the phrase wheel again as it is a
core component of the editing area. Please comment on the
following decisions:

default_word_separators = re.compile('[- \t=+&:address@hidden')
 - words inside a phrase must be separated by any combination
   of at least one of the above
 - "address@hidden", "left-clavicular", "pain=severe", ...
 - the "_" is arguable, IMHO

default_phrase_separators = re.compile('[;/|]+')
 - these indicate completion of a phrase of possibly several
   words, monstrosities such as "//;|;//" will still separate
   just two phrases
 - ";" is your default
 - "/" (and "//") has been observed in practice by me
 - "|" is another one used in lists ("MCU|CRP|ESR")

default_ignored_chars = re.compile("""[?!."'\\(){}\[\]<>~#*$%^]+""")
 - any that I missed or that should be left out ?

The parsing then goeth thus:

- remove ignored_chars
- split at word_separator boundaries

Comments ?
