Problem:
While adding .bib files via "BibTeX Database form," they are sorted
alphabetically. However, sometimes this is not desired. For example, I
put all "@string" into a abbrev.bib file and would like this file to be
listed at first. If there is another aaa.bib file which uses those
@string definitions, auto sorting will result in bibtex error.
Ver: I check 1.2.3 and 1.3.0 and both have this problem.
Root:
FormBibtex.C calls eliminate_duplicates(dbase) to remove duplicates in
dbase. In eliminate_duplicates (defined in lyxalgo.h), dbase is first
sorted.
Fix: (src/support/lyxalgo.h)
A quick patch is to rewrite eliminate_duplicates as
template<class C>
void eliminate_duplicates(C & c)
{
for (size_t i = 1; i < c.size(); ++i) {
typename C::iterator ci = c.begin() + i;
if (std::find(c.begin(), ci, *ci) != ci) {
c.erase(ci);
--i;
}
}
}
This works fine and is efficient for small size c.
If we expect c to be very large (which is very unlikely), we can use:
#include <set> // put this to the beginning of the file
template<class C>
void eliminate_duplicates(C & c)
{
C unique_c;
std::set<typename C::value_type> s;
for (typename C::iterator p = c.begin(); p != c.end(); ++p) {
if (s.count(*p) == 0) {
unique_c.push_back(*p);
s.insert(*p);
}
}
c = unique_c;
}
This patch is against 1.3.0 source. Sorry I didn't check the CVS.
