gott is a go toml transformer. It adds support for go templates in toml files with table-local and global scope (and some selection sugar – dashed and numeric indexes are allowed!). It also bundles the sprig template functions.

Example

# example.toml
[font]
family = "Triplicate"
size = 12

# references can be local, or global
config = "{{.family}} {{.size}}"

[loud]
font-config = "{{.font.config | upper}}"

[loud-copy]
# use the '-' key for splicing other tables into this one.
# with this, you could reference the following path: '.loud-copy.font-config'
- = [ "loud" ]

Usage

Usage of gott:
  -t string
    	Add a toml file to consider
  -T string
    	Add raw toml to consider
  -n string
    	Narrow the namespaces to consider
  -p string
    	Promote a namespace to the top level
  -o string
    	Output type <shell|toml|keys>
  -q string
    	query a value (formatted render: '{{.%s}}')
  -R string
    	Render a string
  -r file
    	Render a file
  -v	be verbose

Output types

toml

# $ gott -t example.toml -o toml
[font]
config = 'Triplicate 12'
family = 'Triplicate'
size = 12

[loud]
font-config = 'TRIPLICATE 12'

shell

$ gott -t example.toml -o shell
font_config='Triplicate 12'
font_family='Triplicate'
font_size='12'
loud_font_config='TRIPLICATE 12'

template renderer

Let’s add another toml file:

# colors.toml
[colors]
solarized = [
    "#eee8d5", "#dc322f", "#859900", "#b58900", "#268bd2", "#d33682", "#2aa198", "#eee8d5",
    "#fdf6e3", "#cb4b16", "#93a1a1", "#839496", "#839496", "#6c71c4", "#93a1a1", "#fdf6e3"
]

$ cat xresources.template
URxvt.font: xft:{{.font.family}}:size={{.font.size}}

{{range $i, $color := .colors.solarized}}
*.color{{$i}}: {{$color}}
{{- end}}

$ gott -t colors.toml -t example.toml -r xresources.template
URxvt.font: xft:Triplicate:size=12

*.color0: #eee8d5
*.color1: #dc322f
*.color2: #859900
*.color3: #b58900
*.color4: #268bd2
*.color5: #d33682
*.color6: #2aa198
*.color7: #eee8d5
*.color8: #fdf6e3
*.color9: #cb4b16
*.color10: #93a1a1
*.color11: #839496
*.color12: #839496
*.color13: #6c71c4
*.color14: #93a1a1
*.color15: #fdf6e3

Shoutouts and Lore

This project exists so I can learn some go. The initial incarnation was written on a train with no internet, where I scrounged through go doc like a caveman. My default dynamic+functional style does not translate well to go, there has been some head banging. The idea of gott is somewhat dynamic in itself, so might be a bad problem for go. Oh well.
