- Did some adhoc work in this repo (the hugo repo that contains this blog) testing out Mage, which is a Go based Make alternative.
- Generated dynamic target directory for hugo posts using stringify for kebab case.
- Unexpected behavior when generating dynamic file path including date.

year, month, day := time.Now().Date()
str := stringy.New(title)
slugTitle := strings.Join([]string{string(year), string(month), string(day), str.KebabCase("?", "").ToLower()}, "-")
|
The output failed to handle the year, resulting in some odd \x18 path generation.
In reviewing the values from returned from time.Now().Date, I realized it wasn’t an int value being returned.
To work through the definition, I figured this would be a good chance to use the cli only to find the docs.
returned the following:
1

package time // import "time"
func Now() Time
Now returns the current local time.
|
To get the source code for the function:
go doc -src 'time.Now'go doc -src 'time.Date'
This shows the return value of Date() is actually time type, not int.
Still couldn’t see where the multiple return parameters were defined so I ran:

go install golang.org/x/tools/cmd/godoc@latest
godoc --http 127.0.0.1:3030

Ok… Figured it out. I was looking at the func Date().
However, what I should have been looking at was the exported method func (Time) Date.
This correctly shows:
1
|
func (t Time) Date() (year int, month Month, day int)
|
I still couldn’t figure this out until I tried running it in the playground.

./prog.go:11:37: conversion from int to string yields a string of one rune, not a string of digits (did you mean fmt.Sprint(x)?)

Runes.
Strings.
I know folks say it boils down to 1’s and 0’s, but dang it… seems like my life always boils down to strings. 😆
Playground - Fixed The Problem
Finally got it all working.
Strongly typed languages are awesome, but this type of behavior is not as easy to figure out coming from a background with dynamic languages. I
In contrast, PowerShell would be: Get-Date -Format 'yyyy'.
Here’s an example of the Mage command then to generate a blog post with a nice selection and prompt.

// calculatePostDir calculates the post directory based on the post title and the date.
func calculatePostDir(title string) string {
year, month, day := time.Now().Date()
str := stringy.New(title)
kebabTitle := str.KebabCase().ToLower()
slugTitle := strings.Join(string(year), string(month), string(day),kebabTitle, "-") ///stringy.ToKebabCase(title)
pterm.Success.Printf("Slugify Title: %s", slugTitle)
filepath := filepath.Join(contentDir, string(year), slugTitle)
pterm.Success.Printf("calculatePostDir: %s", slugTitle)
return filepath
