Hmmm. Maybe.
def convert_bibtex(lines):
bibtex_header = "\\begin_inset LatexCommand \\bibtex"
while 1:
i = find_token(lines, bibtex_header, i)
if i == -1:
break
# We've found a bibtex inset.
# I'd like to strip bibtex_header from the front of lines[i]
# In sed/sh:
line=`echo $line | sed "s/$bibtex_header//"`
# Does the thing have an opt arg?
# I think that this regex is correct, but its not tested.
optarg_rexp = re.compile(r^ *\[([^]]*)\])
optarg = optarg_rexp.search(lines[i])
optarg_contents = ''
if optarg:
optarg_contents = optarg.group(1)
# Can we strip [<optarg_contents>] from the front of lines[i]?
# lines[i] should now contain "{<list of databases>}"
mainarg_rexp = re.compile(r{([^}]*)})
mainarg = mainarg_rexp.search(lines[i])
mainarg_contents = ''
if mainarg:
mainarg_contents = mainarg.group(1)
else:
# complain about a mal-formed lyx file.
# optarg_contents will contain either
# "bibtotoc,<style>"
# or
# "<style>"
# mainarg_contents will contain a comma-separated list of files.
I don't know enough python to proceed futher I'm afraid. Can you fill in the
'ltrim' syntax above and give me a clue about how to proceed?
