determine_url_format()

diagnostic_url_format determine_url_format

(

diagnostic_url_rule_t

rule

)

Determine if URLs should be enabled, based on RULE,
and, if so, which format to use.
This reuses the logic for colorization.

parse_env_vars_for_urls()

static diagnostic_url_format parse_env_vars_for_urls ( )

static

Return URL_FORMAT_XXX which tells how we should emit urls
when in always mode.
We use GCC_URLS and if that is not defined TERM_URLS.
If neither is defined the feature is enabled by default.

parse_gcc_colors()

static bool parse_gcc_colors ( void )

static

Parse GCC_COLORS.  The default would look like:
GCC_COLORS='error=01;31:warning=01;35:note=01;36:\
range1=32:range2=34:locus=01:quote=01:path=01;36:\
fixit-insert=32:fixit-delete=31:'\
diff-filename=01:diff-hunk=32:diff-delete=31:diff-insert=32:\
type-diff=01;32'
No character escaping is needed or supported.
