Table
Print out tabular data on the command line using the ansi color esacape codes. Support for writing the ouput based on the fields in a struct and for defining and creating the table manully using the underlying object.
Support for colors on windows can be don using mattn/go-colorable to make a io.Writer that will work.
Usage
For creating a table yourself using the struct.
tab := table.Table{
Headers: []string{"something", "another"},
Rows: [][]string{
{"1", "2"},
{"3", "4"},
{"3", "a longer piece of text that should stretch"},
{"but this one is longer", "shorter now"},
},
}
err := tab.WriteTable(w, nil) // w is any io.Writer
With a struct slice
data := []struct {
Name string `table:"THE NAME"`
Location string `table:"THE LOCATION"`
}{
{"name", "l"},
{"namgfcxe", "asfdad"},
{"namr3e", "l134151dsa"},
{"namear", "lasd2135"},
}
err := table.MarshalTo(w, data, nil) // writes to any w = io.Writer
buf, err := table.Marshal(data, nil) // also supports return the bytes
The nil parameter is the configuration for the table, this can be set manually, but if its left as nil the deafult config settings will be used.
type Config struct {
ShowIndex bool // shows the index/row number as the first column
Color bool // use the color codes in the output
AlternateColors bool // alternate the colors when writing
TitleColorCode string // the ansi code for the title row
AltColorCodes []string // the ansi codes to alternate between
}
Installation
Go makes this part easy.
