getCSV
Given the following directory structure:
my-project/
└── other-files/
└── pets.csv
Access the data with either of the following:
{{ $data := getCSV "," "other-files/pets.csv" }}
{{ $data := getCSV "," "other-files/" "pets.csv" }}
Access remote data with either of the following:
{{ $data := getCSV "," "https://example.org/pets.csv" }}
{{ $data := getCSV "," "https://example.org/" "pets.csv" }}
The resulting data structure is an array of arrays:
[
["name","type","breed","age"],
["Spot","dog","Collie","3"],
["Felix","cat","Malicious","7"]
]
Options
Add headers to the request by providing an options map:
{{ $opts := dict "Authorization" "Bearer abcd" }}
{{ $data := getCSV "," "https://example.org/pets.csv" $opts }}
Add multiple headers using a slice:
{{ $opts := dict "X-List" (slice "a" "b" "c") }}
{{ $data := getCSV "," "https://example.org/pets.csv" $opts }}
Global resource alternative
Consider using the resources.Get function with transform.Unmarshal when accessing a global resource.
my-project/
└── assets/
└── data/
└── pets.csv
{{ $data := dict }}
{{ $p := "data/pets.csv" }}
{{ with resources.Get $p }}
{{ $opts := dict "delimiter" "," }}
{{ $data = . | transform.Unmarshal $opts }}
{{ else }}
{{ errorf "Unable to get resource %q" $p }}
{{ end }}
Page resource alternative
Consider using the Resources.Get method with transform.Unmarshal when accessing a page resource.
my-project/
└── content/
└── posts/
└── my-pets/
├── index.md
└── pets.csv
{{ $data := dict }}
{{ $p := "pets.csv" }}
{{ with .Resources.Get $p }}
{{ $opts := dict "delimiter" "," }}
{{ $data = . | transform.Unmarshal $opts }}
{{ else }}
{{ errorf "Unable to get resource %q" $p }}
{{ end }}
Remote resource alternative
Consider using the resources.GetRemote function with transform.Unmarshal when accessing a remote resource to improve error handling and cache control.
{{ $data := dict }}
{{ $u := "https://example.org/pets.csv" }}
{{ with resources.GetRemote $u }}
{{ with .Err }}
{{ errorf "%s" . }}
{{ else }}
{{ $opts := dict "delimiter" "," }}
{{ $data = . | transform.Unmarshal $opts }}
{{ end }}
{{ else }}
{{ errorf "Unable to get remote resource %q" $u }}
{{ end }}
