[Solved] Conky, remind, sed and colors

Docbroke · 2023-04-05 08:52:54

I am trying to get calendar, produced by remind, displayed by conky in color.
Here is my conky config file

conky.config = {
    alignment = 'top_right',
    background = true,
    border_width = 1,
    cpu_avg_samples = 1,
    default_color = 'white',
    default_outline_color = 'black',
    default_shade_color = 'yellow',
    draw_borders = false,
    draw_graph_borders = true,
    draw_outline = false,
    draw_shades = false,
    use_xft = true,
    font = 'NotoSansMono Nerd Font:size=8',
    gap_x = 10,
    gap_y = 10,
    minimum_height = 5,
    minimum_width = 5,
    maximum_width = 550,
    net_avg_samples = 2,
    double_buffer = true,
    out_to_console = false,
    out_to_stderr = false,
    extra_newline = false,
    own_window = true,
    own_window_class = 'Conky',
    own_window_type = 'override',
    own_window_transparent = true,
    own_window_argb_visual = true,
    own_window_argb_value = 140,
    own_window_colour = black,
    stippled_borders = 0,
    update_interval = 3.0,
    uppercase = false,
    use_spacer = 'none',
    show_graph_scale = true,
    override_utf8_locale = true
}

conky.text = [[
${execpi 3600 rem -w,0,0 -m -cu+4 |\
 sed 's/TODAY/${color yellow}TODAY$color/;
 s/Sunday/${color green}SUNDAY$color/;
 s/birthday/${color red}BirthDay$color/g;
 ## s/holiday/${color red}HoliDay$color/g; ## This line fails
 s/wedding anniversary/${color red}Anniversary$color/g;
 s/\*/ /g; '}
$if_mpd_playing ${color orange}${font FontAwesome:bold:size=14}${font Shruti:10}${color}${voffset -4}: $mpd_album $mpd_artist $mpd_title$endif
]]

Sed is used to edit remind output and add some conky commands.
This works mostly, keywords like today/birthday are displayed in color, but somehow whatever I do, word holiday refuses to appear in color. What am I doing wrong here?

What's the unfiltered output of

rem -w,0,0 -m -cu+4

?

EDIT: But please don't post personal information, obviously...

Here it is, ( I have just change it to 1 week output only)

$ rem -w,0,0 -m -cu+1

└──────────────┴──────────────┴──────────────┴──────────────┴──────────────┴──────────────┴──────────────┘

Here is output I am getting from conky at present ( with Holiday line removed)

This is the error I get, when that holiday line is changed with sed

sh: -c: line 1: unexpected EOF while looking for matching `''
sh: -c: line 7: syntax error: unexpected end of file

Error gets corrected if I just remove "${color red}" from holiday line. Now I am using similar line for adding color to birthday/sunday etc. but it fails only when I try to add color to holiday. Also only conky gives error, remind and sed works fine.

This is the output without conky involved, but both remind and sed in use

$ rem -w,0,0 -m -cu+1 | sed 's/TODAY/${color yellow}TODAY$color/;
 s/Sunday/${color green}SUNDAY$color/;
 s/birthday/${color red}BirthDay$color/g;
 s/holiday/${color red}HoliDay$color/g;
 s/wedding anniversary/${color red}Anniversary$color/g;
 s/\*/ /g; '
┌──────────┬──────────┬──────────┬──────────┬──────────┬──────────┬──────────┐
│  Monday  │ Tuesday  │Wednesday │ Thursday │  Friday  │ Saturday │  ${color green}SUNDAY$color  │
├──────────┼──────────┼──────────┼──────────┼──────────┼──────────┼──────────┤
│3 Apr     │4 Apr     │5 Apr     │6 Apr     │7 Apr     │8 Apr     │9 Apr     │
│          │${color red}HoliDay$color   │${color yellow}TODAY$color     │POONAM    │${color red}HoliDay$color   │          │          │
│          │Mahavir   │          │          │Good      │          │          │
│          │Jayanti   │          │ABC's 9th │Friday    │          │          │
│          │          │          │${color red}BirthDay$color  │          │          │          │
└──────────┴──────────┴──────────┴──────────┴──────────┴──────────┴──────────┘

So I don't understand why conky don't like "${color red}Holiday$color" but has no problem with "${color red}birthday$color"

What if you defined a red color in your conky config?

EDIT: I'd have to agree with conky, though - holidays shouldn't be red
EDIT#2: Also, how do you feed 'remind' and with what kind of data/format? Config files?

Red is just an example, any color I put there it doesn't work with holidays. Btw., red works just fine with birthday, so red is probably not an issue.

Here is main remind input file

$ cat .config/remind/reminder.rem
BANNER %
include .config/remind/default.rem
include .config/remind/birthdays.rem
include .config/remind/holidays.rem

holidays.rem contains list of holidays, here is a short example

$ cat .config/remind/holidays.rem

OMIT 14 Jan +10 MSG [Ylw]%"holiday MakarSankranti%"[Nrm] %v
OMIT 26 Jan +10 MSG [Ylw]%"holiday Republic Day%"[Nrm] %v
OMIT 24 Mar +10 MSG [Ylw]%"holiday World TB Day%"[Nrm] %v

Similarly birthday is list of birthdays, and other random stuff goes in default

So you're using different formats in the other '.rem' config files? Did you try double quotes with sed (not very well versed in sed on my part...)?

Trilby · 2023-04-05 14:19:01

Double quotes obviously wouldn't work - at least not without a lot of gymnastics to escape all the '$' signs.

Rem and sed really aren't relevant as they are working fine - the problem is with how conky is interpreting that output. If it were me - as a diagnostic test - I'd run the rem/sed command and direct the output to a file, then cat that file from your conky config. If this fails you may get better error information about exactly what part of that file/output was the problem, and it'd be easier to adjust that temporary file to figure out which exact character (or sequence) conky has a problem with.

Docbroke · 2023-04-06 06:09:06

Hi Trilby, I tried to push the rem output using cat as you suggested. It failed with same error as I have posted above (unexpected EOF). So I removed sed lines step by step, ultimately removing all sed lines, still same error. Now it appears that if I use "rem -w,0,0 -m -cu+1" with conky, it works, but if I input output of same command using cat or echo it fails with same error (unexpected EOF while looking for matching ')

EDIT: I have already posted output of "rem -w,0,0 -m -cu+1" in 3rd post of this thread, as well as my entire conky config in first post.

EDIT: forget what is written above, I actually missed to use file as an output. After directing output to a file and then feeding it to conky gives no error. So I solved this by running a shellscript from conky which runs rem/sed and feeds output to conky, instead of running command directly from conky.

Thanks all.

Then the error comes from conky's parsing of the command before it is sent to the shell. I gather conky replaced all the ${..} color codes before passing that command to the shell, and one of those color codes in turn broke the sed command. Theoretically this could be avoided by escaping the '$' symbols, but using a script is likely easier.

Docbroke · 2023-04-06 17:56:19

That may be true.
What is surprising here is, These lines work

s/Sunday/${color green}SUNDAY$color/;
 s/birthday/${color red}BirthDay$color/g;

BUT this doesn't

s/holiday/${color red}HoliDay$color/g;

Trilby · 2023-04-06 20:21:39

That depends what "${color red}" is replaced with. Context matters. For example, an escape character followed by an H is different from that same escape character followed by an S or B.
