SpiderMonkey was updated to mozjs24. If you want to build elinks
with ecmascript support, you must compile using g++ with -fpermissive .
There is a lot of warnings.
There are some memleaks in ecmascript code, especially related to JSAutoCompartment.
I don't know yet, where and how to free it.
Debian does not support mozjs24, so I'm going to gradually update SpiderMonkey version.
Weak points:
- alignof
- js problems
Todo:
- make js work with C++ and mozjs-17
- then mozjs-24
- then mozjs-52
- then mozjs-60
- decrease number of warnings
Fix this warning:
Generating docs for page todo...
todo:12: warning: explicit link request to 'url' could not be resolved
The #url syntax was supposed to refer to the url member of the
containing structure, but it apparently doesn't work when @todo
copies the paragraph to a separate page.
INIT_OPTION used to initialize union option_value at compile time by
casting the default value to LIST_OF(struct option) *, which is the
type of the first member. On sparc64 and other big-endian systems
where sizeof(int) < sizeof(struct list_head *), this tended to leave
option->value.number as zero, thus messing up OPT_INT and OPT_BOOL
at least. OPT_LONG however tended to work right.
This would be easy to fix with C99 designated initializers,
but doc/hacking.txt says ELinks must be kept C89 compatible.
Another solution would be to make register_options() read the
value from option->value.tree (the first member), cast it back
to the right type, and write it to the appropriate member;
but that would still require somewhat dubious conversions
between integers, data pointers, and function pointers.
So here's a rather more invasive solution. Add struct option_init,
which is somewhat similar to struct option but has non-overlapping
members for different types of values, to ensure nothing is lost
in compile-time conversions. Move unsigned char *path from struct
option_info to struct option_init, and replace struct option_info
with a union that contains struct option_init and struct option.
Now, this union can be initialized with no portability problems,
and register_options() then moves the values from struct option_init
to their final places in struct option.
In my x86 ELinks build with plenty of options configured in, this
change bloated the text section by 340 bytes but compressed the data
section by 2784 bytes, presumably because union option_info is a
pointer smaller than struct option_info was.
(cherry picked from elinks-0.12 commit e5f6592ee2)
Conflicts:
src/protocol/fsp/fsp.c: All options had been removed in 0.13.GIT.
src/protocol/smb/smb2.c: Ditto.
Documentation strings of most options used to contain a "\n" at the
end of each source line. When the option manager displayed these
strings, it treated each "\n" as a hard newline. On 80x24 terminals
however, the option description window has only 60 columes available
for the text (with the default setup.h), and the hard newlines were
further apart, so the option manager wrapped the text a second time,
resulting in rather ugly output where long lones are interleaved with
short ones. This could also cause the text to take up too much
vertical space and not fit in the window.
Replace most of those hard newlines with spaces so that the option
manager (or perhaps BFU) will take care of the wrapping. At the same
time, rewrap the strings in source code so that the source lines are
at most 79 columns wide.
In some options though, there is a list of possible values and their
meanings. In those lists, if the description of one value does not
fit in one line, then continuation lines should be indented. The
option manager and BFU are not currently able to do that. So, keep
the hard newlines in those lists, but rewrap them to 60 columns so
that they are less likely to require further wrapping at runtime.
test_search() was supposed to compare bookmark titles with
strcasestr(), but in commit 311d95358d
"bug 153, 1066: Convert bookmarks to/from UTF-8 when searching."
on 2009-02-08, I inadvertently changed that to strcasecmp(), even
while adding a comment about why strcasestr() is needed. strcasestr()
returns non-NULL if the strings match, and strcasecmp() returns
nonzero if they differ, so the search didn't work at all.
In src/bookmarks/dialogs.c, do_add_bookmark() gets the title and URL
in the terminal charset and needs to know which one that is. When a
bookmark is being added, save the struct terminal * to dialog.udata2
and read the charset from there. When a bookmark is being edited,
dialog.udata2 is needed for the struct bookmark *, but there we always
have the parent struct dialog_data * in dialog.udata and can get the
terminal from that.
These functions now expect or return strings in UTF-8:
delete_folder_by_name (sneak in a const, too), bookmark_terminal_tabs,
open_bookmark_folder, and get_auto_save_bookmark_foldername_utf8 (new
function).
SpiderMonkey uses UTF-16 and the strings in struct bookmark are in
UTF-8. Previously, the conversions behaved as if the strings had been
in ISO-8859-1.
SpiderMonkey also supports JS_SetCStringsAreUTF8(), which would make
the existing functions convert between UTF-16 and UTF-8, but that
effect is global so I dare not enable it yet. Besides, I don't know
if that function works in all the SpiderMonkey versions that ELinks
claims to work with.
This also makes the bookmark-update event carry strings in UTF-8.
The only current consumer of that event is bookmark_change_hook(),
which ignores the strings, so no changes are needed there.
When the file is being read, Expat provides the strings to ELinks in
UTF-8, so ELinks can put them in struct bookmark without conversions.
Make sure gettext returns any placeholder strings in UTF-8, too.
Replace '\r' with ' ' in bookmark titles and URLs.
When the file is being written, put encoding="UTF-8" in the XML
declaration, and then write out the strings from struct bookmark
without character set conversions. Do replace some characters
with entity references though, by calling add_html_to_string().
When ELinks is parsing an XML element in from an XBEL bookmark file,
it collects the attributes of the element to the current_node->attrs
list. Previously, struct attributes had room for one string only:
the last element of current_node->attrs was the name of the first
attribute, and it was preceded by the value of the first attribute,
the name of the second attribute, the value of the second attribute,
and so on. However, when get_attribute_value() was looking for a
given name, it compared the values as well. So, if you had for
example <bookmark id="href" href="http://elinks.cz/">, then
get_attribute_value("href") would incorrectly return "href".
To fix this confusion, store values in the new member
attributes.value, rather than in attributes.name.
