I believe I have found a bug in aspell. If you have moved your
aspell .cset and .cmap files to a location that is different from
where they were installed by the build system, you need to use the --
data-dir command line argument to override the aspell's built-in
default search path. Generally this works. However, if you have set
your LANG environment variable to something like en_US, you will get
a error of the form:
Error: The encoding "iso-8859-1" is not known. This could also mean
that the file "/[location of aspell build output]/lib/aspell-0.60/
iso-8859-1.cmap" could not be opened for reading or does not exist.
The problem appears to be in Config::commit_all:
PosibErr<void> Config::commit_all(Vector<int> * phs, const char *
codeset)
{
committed_ = true;
others_ = first_;
first_ = 0;
insert_point_ = &first_;
Conv to_utf8;
if (codeset)
RET_ON_ERR(to_utf8.setup(*this, codeset, "utf-8", NormTo));
while (others_) {
*insert_point_ = others_;
others_ = others_->next;
(*insert_point_)->next = 0;
RET_ON_ERR_SET(commit(*insert_point_, codeset ? &to_utf8 : 0),
int, place_holder);
if (phs && place_holder != -1 && (phs->empty() || phs->back() !
= place_holder))
phs->push_back(place_holder);
insert_point_ = &((*insert_point_)->next);
}
return no_err;
}
Specifically, to_utf8.setup(*this, codeset, "utf-8", NormTo) is
called AFTER the first_ pointer is reset. This means that "data-dir"
config option is not found by the conversion code, and therefore only
the default path is searc. It seems like rearranging the code as
follows would fix the problem:
PosibErr<void> Config::commit_all(Vector<int> * phs, const char *
codeset)
{
Conv to_utf8;
if (codeset)
RET_ON_ERR(to_utf8.setup(*this, codeset, "utf-8", NormTo));
committed_ = true;
others_ = first_;
first_ = 0;
insert_point_ = &first_;
while (others_) {
*insert_point_ = others_;
others_ = others_->next;
(*insert_point_)->next = 0;
RET_ON_ERR_SET(commit(*insert_point_, codeset ? &to_utf8 : 0),
int, place_holder);
if (phs && place_holder != -1 && (phs->empty() || phs->back() !
= place_holder))
phs->push_back(place_holder);
insert_point_ = &((*insert_point_)->next);
}
return no_err;
}
Are there any side-effects to doing this that I'm not aware of?
