# Convert a lyx file to recoll HTML.
|
||||||
|
#
|
||||||
|
# We use lyx --export. It was suggested to use untex, but it doesn't give
|
||||||
|
# good results on raw lyx (of course, this is not TeX), and exporting to
|
||||||
|
# LaTex then using untex doesn't look nice when we can use the native lyx
|
||||||
|
# text export.
|
||||||
|
# The character encoding of the exported text is defined by the
|
||||||
|
# \inputencoding directive in the lyx file header and, in quite an obscure
|
||||||
|
# way, by the \language parameter. We use a heuristic to divine the output
|
||||||
|
# text encoding and it is guaranteed not to work in all cases. Trials using
|
||||||
|
# an intermediary dvi, pdf or ps file gave worse results. This needs
|
||||||
|
# improvement. It doesn't even take into account the fact that the language
|
||||||
|
# can change inside the doc (does this change the encoding or not ?). To be
|
||||||
|
# frank, this is not entirely my fault, the lyx format is a joke.
|
||||||
|
#
|
||||||
|
# As there is unfortunately no way to define the output file name, we have
|
||||||
|
# to use a temporary directory and link the input file in there.
