Learning how to code

2023-01-09

If you find yourself doing the same task repeatedly, consider learning how to code.

For instance, a friend of mine had to perform the following tasks on daily basis:

logging into a internal portal
selecting certain menus
exporting some .xlsx reports
opening various excel files
clicking on the “Refresh All” button to update external data
sending an email

Here’s the code that I assisted him with: https://github.com/quantonganh/ims

The initial steps can be done by using chromedp.

As an engineer, I want to automate everything as much as possible. This CLI tool is created to save a draft mail in Zimbra web client.

Read config file:

 1func initConfig() {
 2	if cfgFile != "" {
 3		// Use config file from the flag.
 4		viper.SetConfigFile(cfgFile)
 5	} else {
 6		// Find home directory.
 7		home, err := homedir.Dir()
 8		if err != nil {
 9			fmt.Println(err)
10			os.Exit(1)
11		}
12
13		// Search config in home directory with name ".zwc" (without extension).
14		viper.AddConfigPath(home)
15		viper.SetConfigName(".zwc")
16	}
17
18	viper.AutomaticEnv() // read in environment variables that match
19
20	// If a config file is found, read it in.
21	if err := viper.ReadInConfig(); err != nil {
22		log.Fatal(err)
23	}
24
25	fmt.Println("Using config file:", viper.ConfigFileUsed())
26}
