Go R1 Day 10

Day 10 of 100

progress

• Experimented with CLI tool using go-prompt
• Customized initial options
• OS independent call to get user home directory.
• Iterated through a directory listing
• Used path join to initialize path for directory search.
• One challenge in working with structs being returned was figuring out how to print the values of the struct. Initially, I only had pointers to the values coming back. This made sense, though, as I watched a tutorial this weekend on slices, and better understand that a slice is actually a small data structure being described by: pointer to the location in memory, length, and the capacity of the slice. Without this tutorial, I think seeing the pointer addresses coming through would have been pretty confusing.
• In reading StackOverflow, I realized it’s a “slice of interfaces”.
• Worked with apex logger and moved some of the log output to debug level logging.
• Final result
