Sorry to bother you!
I'm sure this insignificant script displaying a month
-- colored with some colors in the 90's register of ANSI codes
-- fading according to in-focus and out-of-focus
-- with the single numbers of the month padded
-- with a little motto at the bottom (hopefully inspiring!)
-- using < rxvt > and < less > to produce a pseudo-GUI
-- multilingual (plus you could add your own locale)
-- with a suggested entry for a pekwm or ae menu
is off-topic and of no interest to anyone!

French version (sorry to impose).
But if LANG variable NOT set to fr, will display in English. |

I'm working on something similar with coloring done it this way (without curses it will be hard to make windows and menus but i'm thinking to use 'select' or 'tput' command):
| Code: | | cal | grep -w --color=always "$(seq 1 2 31)" | sed 's/31m/32m/g' |
or
| Code: | | a=$(cal | grep -w --color=always "$(seq 1 2 31)"); echo "${a//31m/34m}" |
| Code: | | cal | grep -w -B 6 -A 6 --color=always 10 | sed 's/31m/32m/g' | grep -w -B 6 -A 6 --color=always 20 |
where '31' is standard color from grep command.

Thank you for fixing that nasty bug 
I like your idea of using "pipe-separated values" as a part of a regexp. It is also possible to apply this technique to the entire year view:
| Code: | #!/bin/bash
# Highlights dates from two sets in the cal command output
# using distinct styles (in the month and year view).
# Requires GNU sed. Busybox sed doesn't understand multibytes chars
# (it seems to be the compile option).
# It also doesn't support s/.../.../Ng options combo
# but this can be worked around:
#
# mark_days="$mark_days
# $addr,+6 { s/./!/22; s/./!/44; s/...?!?/%$i-&/g
# :a$i; s/(!.*%)$i/\1$((i+1))/; ta$i; s/!/ /
# :b$i; s/(!.*%)$((i+1))/\1$((i+2))/; tb$i; s/!/ /
# }"
#
# Usage: ./this_script [ [month] year ]
# No error checking. This is just a demo.
# cal and busybox cal insert empty lines in different places
CALCMD="busybox cal" addr=4 inc=8
#CALCMD="cal -h" addr=3 inc=9
# Highlight:
# 1st set of days
daysA="1-1|1-7|12-25|12-26|12-31"
# 2nd set of days
daysB="1-2|12-31"
# columns
daysC="1|6|7"
# Styles:
onA=$'\x1b[1;37;42m' # for the 1st set
offA=$'\x1b[0m' # turn the style off
onB=$'\x1b[1;35m' # for the 2nd set
offB="$offA"
onAB=$'\x1b[1;37;45m' # for the intersection of the two sets
offAB="$offA"

Probably the easiest way to test busybox awk is by downloading a statically compiled binary from the official site.
https://busybox.net/downloads/binaries
| Code: | root# busybox awk
awk: applet not found
root# chmod 755 busybox-i686
root# ./busybox-i686 awk
BusyBox v1.28.1 (2018-02-15 14:34:02 CET) multi-call binary.
Usage: awk [OPTIONS] [AWK_PROGRAM] [FILE]...
-v VAR=VAL Set variable
-F SEP Use SEP as field separator
-f FILE Read program from FILE
-e AWK_PROGRAM |

Well done!
I never thought that anyone would try to do this 
| Quote: | | Busybox sed doesn't understand multibytes chars |
Well, it understands multibyte chars when inserted directly or via variable, not when the chars are represented by escape codes. But I don't see such chars in your code. I only see that busybox sed doesn't work. Can you point me to an expression where busybox sed fails?
These binaries seem to be compiled with CONFIG_LOCALE_SUPPORT not enabled. They are English only. It would be great if you or anyone else knows where to download a recent busybox with support for locales.

OK, this is a bit late respond but anyway...

There are several problems with busybox here.
Multibyte characters may appear in the cal command output and what busybox sees is a bytestring. This means that I can't use dots in the regexps.
| Code: | # echo "żółw" | busybox sed 's/./1/g' | wc -c
8
# echo "żółw" | sed 's/./1/g' | wc -c
5 |
Now, a command like s/a/b/5g fails because busybox ignores the number and replaces all the matches.
And the old versions of busybox have a bug: s/a/b/5; results in an unrecognized option error while s/a/b/5 ; (with a space before ; ) works.
And addresses like 1,+2 aren't supported by the old busybox versions.
I've rewritten the script so it should work with busybox now.
| Code: | #!/bin/busybox sh
# Highlights dates from two sets in the cal command output
# using distinct styles (in the month and year view).
# This version outputs an HTML document.
# Should work with busybox utilities.
# Usage: ./this_script [ [month] year ] >cal.html
# No error checking. This is just a demo.
# cal and busybox cal insert empty lines in different places

Hello all.
Please find attached a variant of my "completely useless" DB-type
approach above: | Code: | #!/bin/bash

# is a safeguard: it defaults to current month and year if the
# script finds no positional parameters.

Are you by any chance using the busybox version you recommended for download? As you've already noticed and I said before: this version is English only. Any of the Puppy busybox versions should produce the correct result of 5.
| Quote: | | Now, a command like s/a/b/5g fails because busybox ignores the number and replaces all the matches. |
It doesn't "fail", it only tries to make sense of an ambiguous command. What do you expect it to produce when you instruct it to a) replace only the 5th match? and b) replace all matches ?
When you use two contradicting flags, newer busyboxes ignore the first flag and honor only the last:
| Code: | # echo a..a...a...a..a | busybox sed s/a/X/3g
X..X...X...X..X |
If you change the order of the flags in the example, busybox will ignore 'g':
| Code: | # echo a..a...a...a..a | busybox sed s/a/X/g3
a..a...X...a..a |
This is also the result I get from my older busybox 1.21.0, regardless of the g3 order.
GNU sed output is still different. Matches from the 3rd to the last are replaced, matches before the 3rd are ignored.
Bottomline: avoid ambiguous commands.
