我想连接两个 figlet 输出(不同颜色)

I would like to concatenate two figlet outputs (with different colors)

目前我有这样的输出格式:

{ echo "$(figlet buddhi)"; echo "$(figlet lw)"; }
 _               _     _ _     _
| |__  _   _  __| | __| | |__ (_)
| '_ \| | | |/ _` |/ _` | '_ \| |
| |_) | |_| | (_| | (_| | | | | |
|_.__/ \__,_|\__,_|\__,_|_| |_|_|

 _
| |_      __
| \ \ /\ / /
| |\ V  V /
|_| \_/\_/


我想要这样的输出格式:

figlet buddhi lw
 _               _     _ _     _   _
| |__  _   _  __| | __| | |__ (_) | |_      __
| '_ \| | | |/ _` |/ _` | '_ \| | | \ \ /\ / /
| |_) | |_| | (_| | (_| | | | | | | |\ V  V /
|_.__/ \__,_|\__,_|\__,_|_| |_|_| |_| \_/\_/

原因是:我想给每个名字(buddhi, lw)涂上不同的颜色。但是,保留连续字符串的格式,或者最多 space 分隔,如上所述。

示例:

 #COMMANDS CREATED INSIDE /ETC/BASH.BASHRC FILE
 # USING ANSI COLORS
 RED="\e[31m"
 ORANGE="\e[33m"
 BLUE="\e[94m"
 GREEN="\e[92m"
 STOP="\e[0m"


 printf "${GREEN}"
 printf "=================================\n"
 printf "${ORANGE}"
 figlet -f standard "Buddhi"
 printf "${BLUE}"
 figlet -f  small "LW"
 printf "${GREEN}"
 printf "=================================\n"
 printf "${STOP}"

将每个单词的行存储在数组中,逐行输出两个数组。由于“Buddhi”的第一行好像少了一个字,所以我把第一个字的最长行长存到一个变量里,用%-s的格式来填充每一行。

#! /bin/bash
RED="\e[31m"
ORANGE="\e[33m"
BLUE="\e[94m"
GREEN="\e[92m"
STOP="\e[0m"

mapfile -t left  < <(figlet -f standard "Buddhi")
mapfile -t right < <(figlet -f small    "LW")

maxlength=0
for line in "${left[@]}" ; do
    if (( ${#line} > maxlength )) ; then
        maxlength=${#line}
    fi
done

printf "${GREEN}"
printf "=================================\n"

for ((i=0; i<=${#left[@]}; ++i)) ; do
    printf "${ORANGE}%-${maxlength}s ${GREEN}%s\n" "${left[i]}" "${right[i]}"
done

printf "${GREEN}"
printf "=================================\n"
printf "${STOP}"

代替 figlet 我将使用以下内容作为我的输入:

$ cat buddhi
 _               _     _ _     _
| |__  _   _  __| | __| | |__ (_)
| '_ \| | | |/ _` |/ _` | '_ \| |
| |_) | |_| | (_| | (_| | | | | |
|_.__/ \__,_|\__,_|\__,_|_| |_|_|

$ cat lw
 _
| |_      __
| \ \ /\ / /
| |\ V  V /
|_| \_/\_/

假设figlet为每个输入字符串生成相同数量的输出行,我们可以使用paste@作为分隔符)和while/read循环来生成所需的输出:

printf "${GREEN}"
printf "============================\n"

maxwidth=$(awk '{max=length([=11=]) > max ? length([=11=]) : max}END{print max}' buddhi)

while IFS='@' read -r col1 col2
do
    printf "${ORANGE}%-*s ${BLUE}%s\n" "${maxwidth}" "${col1}" "${col2}"
done < <(paste -d"@" buddhi lw)

printf "${GREEN}"
printf "============================\n"

这会生成:


扩展到 3 个输入流:

printf "${GREEN}"
printf "============================\n"

max1=$(awk '{max=length([=12=]) > max ? length([=12=]) : max}END{print max}' buddhi)
max2=$(awk '{max=length([=12=]) > max ? length([=12=]) : max}END{print max}' lw)

while IFS='@' read -r col1 col2 col3
do
    printf "${ORANGE}%-*s ${BLUE}%-*s ${RED}%s\n" "${max1}" "${col1}" "${max2}" "${col2}" "${col3}"
done < <(paste -d"@" buddhi lw buddhi)

printf "${GREEN}"
printf "============================\n"

这会生成:

如果您需要更短的版本:

printf "$GREEN=================================\n"
{ figlet Buddhi; echo 'EOF'; figlet LW; } | awk 'NF==1&&=="EOF" {noskip=1; next; } noskip==0 { f[++c]=[=10=]; next; } { printf "%s%s%s%s\n","'"$ORANGE"'",f[++k],"'"$BLUE"'",[=10=];}'
printf "$GREEN=================================\n"
tput sgr0

我建议使用 tput 来设置颜色,因为并非每个终端都知道您的转义序列

发明 shell 的人也发明了 awk 供 shell 调用来操作文本。这些转义序列不会在我的终端上改变颜色,它们只是按原样显示(幸运的是你可以看到脚本将它们放在哪里):

$ cat tst.sh
#!/usr/bin/env bash

awk '
    BEGIN {
        red =    "\e[31m"
        orange = "\e[33m"
        blue =   "\e[94m"
        green =  "\e[92m"
        stop =   "\e[0m"
    }
    {
        val[(NR==FNR),FNR] = [=10=]
    }
    NR == FNR {
        wid = length([=10=])
        maxWid = ( wid > maxWid ? wid : maxWid )
    }
    END {
        for ( lineNr=1; lineNr<=FNR; lineNr++ ) {
            printf "%s%-*s%s%s%s\n", orange, maxWid, val[1,lineNr], blue, val[0,lineNr], stop
        }
    }
' <(cat Buddhi) <(cat LW)

$ ./tst.sh
\e[33m _               _     _ _     _ \e[94m _\e[0m
\e[33m| |__  _   _  __| | __| | |__ (_)\e[94m| |_      __\e[0m
\e[33m| '_ \| | | |/ _` |/ _` | '_ \| |\e[94m| \ \ /\ / /\e[0m
\e[33m| |_) | |_| | (_| | (_| | | | | |\e[94m| |\ V  V /\e[0m
\e[33m|_.__/ \__,_|\__,_|\__,_|_| |_|_|\e[94m|_| \_/\_/\e[0m

因为我没有 figlet,所以我 运行 这些文件的以上内容:

$ head Buddhi LW
==> Buddhi <==
 _               _     _ _     _
| |__  _   _  __| | __| | |__ (_)
| '_ \| | | |/ _` |/ _` | '_ \| |
| |_) | |_| | (_| | (_| | | | | |
|_.__/ \__,_|\__,_|\__,_|_| |_|_|

==> LW <==
 _
| |_      __
| \ \ /\ / /
| |\ V  V /
|_| \_/\_/

只需更改脚本的最后一行:

' <(cat Buddhi) <(cat LW)

' <(figlet Buddhi) <(figlet LW)

使用实际 figlet 输出。

以上假定您只有 2 个 figlet 输出字符串要连接并且两组输出的长度相同,如果这些假设中的任何一个是错误的,很容易调整。

使用坐标

#!/bin/bash

RED='\e[31m'
GRN='\e[32m'

XY(){ printf "\e[;H"; }

mapfile -t frst < <(figlet -f standard "Buddhi")
mapfile -t scnd < <(figlet -f small    "LW")

XY 1 1 "$GRN==============================================="; y=2
for line in "${frst[@]}"; { XY 0  $y "$RED$line"; ((y++)); }; y=2
for line in "${scnd[@]}"; { XY 35 $y "$GRN$line"; ((y++)); }
XY 1 8 "$GRN==============================================="
