gotmpl

Description

gotmpl is a super simple command line program for rendering templates. gotmpl uses environment variables as its context and go-adaptive-functions for its functions. gotmpl uses go-simple-serializer for parsing text into data, such as in the "Render Time Table" example below.

Installation

No installation is required. Just grab a release. You might want to rename your binary to just gotmpl for convenience.

If you do have go already installed, you can just run using go run main.go or install with make install

Usage

See the few examples below.

Note: Since Go templates add the piped value to the end of the positional argument array, gotmpl reorders the piped value to the beginning of the argument array, so go-adaptive-functions can be used. This leads to a more seamless pattern, particularly for functions such as split, join, etc.

Examples

Get Shell

echo '{{ split .SHELL "/" | last }}' | gotmpl

Clean Path

echo '{{ .PATH | split ":" | set | array | sort | join ":" }}' | gotmpl

Render Time Table

echo '{{ with $items := .data | parse "csv" }}<table style="text-align:left;font-size:16px;"><tr><th>Time</th><th>Title</th>{{ range $items }}<tr><td>{{ .Time }}</td><td>{{ .Title }}</td></tr>{{ end }}</table>{{ end }}' | data=$(cat timetable.csv) gotmpl

Testing

Run tests with make test (or bash scripts/test.sh), which runs unit tests, go vet, go vet with shadow, errcheck, ineffassign, staticcheck, and misspell.
