在i3wm狀態欄顯示股票信息

效果如圖:

創建腳本,並賦可執行權限:

~/.i3/myi3status.sh

#!/bin/sh
# shell script to prepend i3status with more stuff

STOCK_SCRIPT=`realpath "$0"|xargs dirname`/stock.php

i3status | while :
do
    stock_info=""
    if [[ -x "$STOCK_SCRIPT" ]]; then
        stock_info=`$STOCK_SCRIPT`
    fi

    read line

    # if output_format = i3bar in i3status.conf
    stock_info="[{ \"full_text\": \"${stock_info}\" },"
    echo "${line/[/$stock_info}" || exit 1

    # # if not output_format = i3bar in i3status.conf
    # echo "$stock_info | $line" || exit 1
done

如果i3status.conf中啟用了JSON格式輸出(支持顏色),應啟用上面腳本中第一塊的代碼,否則使用後面的。啟動JSON格式輸出的內容具體如下:

~/.i3status.conf
1
2
3
4
general {
    colors = true
    output_format = i3bar
}

在i3wm的配置文件中用以上腳本替換i3status:

~/.i3/config
1
2
3
4
5
6
7
8
9
10
bar {

    # ...

    # status_command i3status
    status_command ~/.i3/myi3status.sh

    # ...

}

在和上面腳本同路徑下創建腳本:

~/.i3/stock.php
