[PATCH v8 0/7] perf config: Introduce default config key-value pairs arrays

[PATCH v8 0/7] perf config: Introduce default config key-value pairs arrays

[Taeung Song]

Hello, :)

When initializing default perf config values,
we currently use values of actual type(int, bool, char *, etc.).
But I suggest using default config key-value pairs arrays.

For example,
If there isn't a user config value for 'annotate.use_offset'
config variable at ~/.perfconfig,
default value for it is 'true' bool type value in perf like below.

At ui/browsers/annoate.c

static struct annotate_browser_opt {
       bool hide_src_code,
            use_offset,
	    jump_arrows,
	    show_linenr,
	    show_nr_jumps,
	    show_total_period;
} annotate_browser__opts = {
       .use_offset      = true,
       .jump_arrows     = true,
};

But if we use new config arrays that have all default config key-value pairs,
we could initialize default config values with them.

If we do, we can manage default perf config values at one spot (like util/config.c)
and It can be easy and simple to modify existing default config values or
add default values for new config item.

For example,
If we use new default config arrays and there isn't user config value for 'annoate.use_offset'
default value for it will be set as annotate_config_items[CONFIG_ANNOATE_USE_OFFSET].value.b
instead of actual boolean type value 'true'.

IMHO, I think it would needed to use new default config arrays
to manage default perf config values more effectively.
And this pathset contains patchs for only 'colors' and 'annoate' section
because waiting for other opinions.

If you review this patchset, I'd appreciate it :-)

Thanks,
Taeung

But I suggest using 'struct default_config_section' and
'struct default_config_item' that can contain default config key-value pairs
in order to initialize default config values with them, in near future.

If we do, we could manage default perf config values at one spot (i.e. util/config.c)
with default config arrays and it could be easy and simple to modify
existing default config values or add default values for new config item.

[PATCH v8 2/7] perf config: Add macros assigning key-value pairs to default_config_item

[Taeung Song]

In near future, default_config_item arrays will be added
(e.g. const struct default_config_item colors_config_items[])
To simply assign config key-value pairs to default_config_item,
add macros that are CONF_VAR() and CONF_*_VAR() for each type.

[PATCH v8 3/7] perf config: Add default section and item arrays for 'colors' config

[Taeung Song]

Actual values for default configs of 'colors' section is like below.

(at ui/browser.c)
static struct ui_browser_colorset {
	const char *name, *fg, *bg;
	int colorset;
} ui_browser__colorsets[] = {
	{
		.colorset = HE_COLORSET_TOP,
		.name	  = "top",
		.fg	  = "red",
		.bg	  = "default",
	},
...

But I suggest using default config arrays for 'colors' section that
contain all default config key-value pairs for it.

In near future, this array will be used on ui/browser.c
because of setting default values of actual variables for 'colors' config.

[PATCH v8 4/7] perf config: Use combined {fore,back}ground colors value instead of each two color

[Taeung Song]

To easily set default config values into actual variables for 'colors' config,
it would be better that actual variables for each 'colors' config
have only one value like 'default_config_item' type.

If we use combined {fore,back}ground colors values in ui_browser_colorset,
it smoothly work to initialize default config values for 'colors' config
by 'colors_config_items' array that contains default values for it at util/config.c.
because both actual variable and config item of 'colors_config_items'
are equal in the number of values (as just one).

[PATCH v8 6/7] perf config: Add default section and item arrays for 'annotate' config

[Taeung Song]

Actual values for default configs of 'annotate' section is like below.

        bool hide_src_code,

             jump_arrows,

} annotate_browser__opts = {
        .use_offset      = true,
        .jump_arrows     = true,
};

But I suggest using default config arrays for 'annotate' section that

In near future, this arrays will be used on ui/browsers/annoate.c
because of setting default values of actual variables for 'annotate' config.
