From 6e4136753bd0faa15c198118b05c529d96d908c5 Mon Sep 17 00:00:00 2001 From: Alvar Penning Date: Mon, 24 Apr 2023 22:01:23 +0200 Subject: sfeed_{curses,frames,gopher,html,plain}: SFEED_NEW_MAX_SECS By introducing the new environment variable $SFEED_NEW_MAX_SECS in all sfeed_* utilities marking feeds as new based on comparing their age, it is now possible to override this age limit. This allows, for example, to be notified about new feeds within the last hour with SFEED_NEW_MAX_SECS=3600 sfeed_plain ~/.sfeed/feeds/* while creating a beautiful web report for last week's news by SFEED_NEW_MAX_SECS=604800 sfeed_html ~/.sfeed/feeds/* --- sfeed_html.1 | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'sfeed_html.1') diff --git a/sfeed_html.1 b/sfeed_html.1 index efeb289..98784c5 100644 --- a/sfeed_html.1 +++ b/sfeed_html.1 @@ -26,9 +26,16 @@ is empty. .Pp Items with a timestamp from the last day compared to the system time at the time of formatting are counted and marked as new. +This value might be overridden through environment variables.

Some changes and notes: - Change it so it is OK to set this value to 0 or negative (in the future). - sfeed_curses: truncating newmaxsecs to an int would limit the value too much. - Just use strtotime() and parse the value to time_t. This is a signed long (32-bit, until 2038) or signed long long (64-bit) on most platforms. - sfeed_curses gets the comparison time on reload aswell and it needs errno = 0, because it uses die(). time() is not guaranteed to set an errno if it fails. - Rename environment variable to $SFEED_NEW_AGE. --- README | 6 +++--- sfeed_curses.1 | 2 +- sfeed_curses.c | 13 +++---------- sfeed_frames.1 | 2 +- sfeed_frames.c | 17 +++-------------- sfeed_gopher.1 | 2 +- sfeed_gopher.c | 17 +++-------------- sfeed_html.1 | 2 +- sfeed_html.c | 17 +++-------------- sfeed_plain.1 | 2 +- sfeed_plain.c | 18 +++--------------- util.c | 18 ++++++++++++++++++ util.h | 1 + 13 files changed, 42 insertions(+), 75 deletions(-) (limited to 'sfeed_html.1') diff --git a/README b/README index 313ab4c..427435d 100644 --- a/README +++ b/README @@ -290,9 +290,9 @@ Just like the other format programs included in sfeed you can run it like this: sfeed_curses < ~/.sfeed/feeds/xkcd By default sfeed_curses marks the items of the last day as new/bold.
