This modules offer several free functions to help with lyx2lyx'ing.
|
|
More documentaton is below, but here is a quick guide to what
|
|
they do. Optional arguments are marked by brackets.
|
|
|
|
add_to_preamble(document, text):
|
|
Here, text can be either a single line or a list of lines. It
|
|
is bad practice to pass something with embedded newlines, but
|
|
we will handle that properly.
|
|
The routine checks to see whether the provided material is
|
|
already in the preamble. If not, it adds it.
|
|
Prepends a comment "% Added by lyx2lyx" to text.
|
|
|
|
insert_to_preamble(document, text[, index]):
|
|
Here, text can be either a single line or a list of lines. It
|
|
is bad practice to pass something with embedded newlines, but
|
|
we will handle that properly.
|
|
The routine inserts text at document.preamble[index], where by
|
|
default index is 0, so the material is inserted at the beginning.
|
|
Prepends a comment "% Added by lyx2lyx" to text.
|
|
|
|
put_cmd_in_ert(arg):
|
|
Here arg should be a list of strings (lines), which we want to
|
|
wrap in ERT. Returns a list of strings so wrapped.
|
|
A call to this routine will often go something like this:
|
|
i = find_token('\\begin_inset FunkyInset', ...)
|
|
j = find_end_of_inset(document.body, i)
|
|
content = lyx2latex(document[i:j + 1])
|
|
ert = put_cmd_in_ert(content)
|
|
document.body[i:j+1] = ert
|
|
|
|
lyx2latex(document, lines):
|
|
Here, lines is a list of lines of LyX material we want to convert
|
|
to LaTeX. We do the best we can and return a string containing
|
|
the translated material.
|
|
|
|
latex_length(slen):
|
|
Convert lengths (in LyX form) to their LaTeX representation. Returns
|
|
(bool, length), where the bool tells us if it was a percentage, and
|
|
the length is the LaTeX representation.
|
|
