This makes it possible for the compiler to do better optimizations by
adding "static" to functions which do not need to be exported.
Since some of them (e.g. the compare_*() functions) are called very
often, this may decrease conky's need of resources a bit.
With my last patch I did only update the XML documentation file without
updating the auto-generated manpage and README file.
This patch also updates README and conky.1.
Since there is no choice of which moc player to get information from,
all moc objects' data source can be identical. Also hide some internal
data (the thread e.g.). Since from now on there can only be one moc
thread (not highlander ;), we don't need to treat the thread object
specially.
While here, fix indenting.
All objects parsing text into objects formerly parsed and evaluated
their arguments each update interval. This does only make sense when the
parsed text could change between updates, which is the case for execp
and execpi objects, but none of the others. So have them parse the text
when creating them, so each update interval only the output has to be
re-extracted.
In fact, this should give a performance boost when using any of the
affected objects, as parsing the input text is quite expensive since
we're evaluating templates.
Using a global ifblock stack for all parsed ifblock objects causes
problems when doing sub-parsing in objects taking other objects as
parameters, because the possibly non-empty stack at startup leads to
false alarm when checking for stack emptiness after parsing the objects.
Use a void ** as the object to pass around, so callers don't need to
know struct ifblock_stack_obj.
In fact, they are. But we don't want to treat them as those, because
the rewrite made the only situation when threaded objects matter
uncritical, i.e. when an object calls calling parse_conky_vars().
In general, argument types should match, but for combined long and
double usage the long is being converted to double before evaluation.
A few examples:
${if_match ${cpu} < 30}
${if_match "asdf" != "qwer"}
${if_match 0.5 < 0.50001}
${if_match 49.999 < 50}
The crux is to split args between those for scan_graph() on one hand and
prepare_diskio_stat() on the other hand. To make the code working with
minimal changes, move the yet optional devicename to the end.
General note on graphs:
- for all graphs there exist the optional arguments for scan_graph()
which come first and are optional (intended duplicate)
- all other args are object specific, and may be optional as well
Handle mpd internal information inside mpd.c. Use a refcounter to check
if the mpd-information can be freed (maybe useless). Remove the now
useless "full" flag of free_text_objects.
This was a bug, not a feature. From the FreeBSD manpage rtentry(9):
| Vt struct sockaddr *rt_gateway;
|
| The "target" of the route, which can either represent a destination in
| its own right (some protocols will put a link-layer address here), or
| some intermediate stop on the way to that destination (if the
| RTF_GATEWAY flag is set).
So for a default route with "dest" and "mask" both zero, either
RTF_GATEWAY is present, or "gate" is zero.
The only change of behaviour occurs when adjusting the unit of positive
values. For some reason 1000LL was used, which has now been replaced by
1024LL. Usage of abs() and MAX() might be OS dependent, but it should
not be too hard to implement them by hand if they're missing somewhere.
It was a static int before, holding the (already defined) enum's value,
which doesn't make sense. Also it's used only inside conky.c. Since
enums can't be assigned other values than what are defined, we can skip
checking for illegal spacer value at each invocation of spaced_print,
and then also drop the function name argument, which apparently didn't
make sense at all, because use_spacer is a global option.
Instead of splitting information, use diskio_stats[0] in diskio.c for
the totals. This saves a few branches, and frees some data from struct
information.
Some statics are now defined by configure.ac.in, conky.h got a lot
smaller, which I see as a positive sign.
This patch should not change any functionality, just change what's
defined where. Some features I did/could not test are probably broken,
also compiling for any other OS surely won't complete now. Though I
think fixing these problems is as easy as including some missing
headers.
I've done compile checks with the following configure options:
./configure --enable-eve --enable-rss --enable-smapi
--enable-wlan --enable-debug --enable-testing
So what needs to be tested is:
- audacious
- BMPx
- xmms2
- nvidia
Using a macro is not possible anymore, so have a function dev_name() do
the job. Functionality is the same as the old DEV_NAME, unless the
specified path is a symlink in which case it's being dereferenced first.
To save callers from having to free the returned string, a static local
buffer is used (effectively rendering the function non-reentrant).
