Use dynamic allocated memory for skey and svalue,
allocate the length of value so that there are no limits,
but don't use the %a gnu extension to maintain compatibility
This patch is written by a anonymous author, see patch on sf.net
id #2663691 . I changed it a bit so that it can't overwrite
existing environment variables and updated the docs and syntaxfiles
As a side effect, font and colour specific stuff got outsourced, too.
This is because the apropriate functions are used by conky.c as well as
specials.c, so they should be kept on their own.
In the long term I hope for positive impact on the X11 integration mess.
(Take e.g. the mass of X11 ifdefs cluttering conky.c.) Though this
commit contains no optimisations in this direction, just plain
outsourcing, to ensure minimised (intended: none) changes to conky's
interface behaviour.
In fact these two objects share a lot of code, so the bigger plan is to
merge them into a single file to share equal code.
This should not change anything to the code flow, besides making conky
startup a bit more robust due to less use of CRIT_ERR.
Well, not really. I don't dare putting it all together into a single
source file, as that would just not make sense. Instead, this patch
eliminates the --enable-smapi configure option and all related checks,
replacing them with the equivalents from --enable-ibm.
Despite this is actually not much code and could stay inside linux.c as
well, this makes sense as I want to combine smapi and ibm-acpi
functionality. Virtually every user of a notebook made by IBM/Lenovo
will want both, so this should be a feature not a bug.
Besides making the ibm-acpi objects being built optionally, this should
not change anything to the code flow.
Also, note that free() does not zero the passed pointer. So conditional
freeing always needs to look like this:
| if (var) {
| free(var);
| var = 0;
| }
* change the height of execbar and execibar to be the same as other
bars have by default (6 pixels)
* treat mixer values as percentages as they're usually 0-100 (switch
to spaced_print() with pad_percents)
* change temp_print() from snprintf() to spaced_print()
* remove decimals from temp_print() as none of the current sources can
supply values smaller than 1 degree (C or F, doesn't matter)
* add a space between number and the unit in human_readable()
* fix number printing in human_readable()
* network $upspeed and $downspeed now use human_readable()
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().
