**The project is in maintenance mode.**
It is kept compatible with changes in the Go ecosystem but no new features will be developed. PR could be accepted.
# Install
`go get github.com/artonge/go-csv-tag/v2`
# Example
## Load
The csv file:
```csv
name, ID, number
name1, 1, 1.2
name2, 2, 2.3
name3, 3, 3.4
```
Your Go code:
```go
type Demo struct { // A structure with tags
Name string `csv:"name"`
ID int `csv:"ID"`
Num float64 `csv:"number"`
}
tab := []Demo{} // Create the slice where to put the content
err := csvtag.LoadFromPath(
"file.csv", // Path of the csv file
&tab, // A pointer to the create slice
csvtag.CsvOptions{ // Load your csv with optional options
Separator: ';', // changes the values separator, default to ','
Header: []string{"name", "ID", "number"}, // specify custom headers
TagKey: "csv", // specify a custom tag key, default to 'csv'
})
```
You can also load the data from an io.Reader with:
```go
csvtag.LoadFromReader(youReader, &tab)
```
Or from a string with:
```go
csvtag.LoadFromString(yourString, &tab)
```
## Dump
Your Go code:
```go
type Demo struct { // A structure with tags
Name string `csv:"name"`
ID int `csv:"ID"`
Num float64 `csv:"number"`
}
tab := []Demo{ // Create the slice where to put the content
Demo{
Name: "some name",
ID: 1,
Num: 42.5,
},
}
err := csvtag.DumpToFile(tab, "csv_file_name.csv")
```
You can also dump the data into an io.Writer with:
```go
err := csvtag.DumpToWriter(tab, yourIOWriter)
```
Or dump to a string with:
```go
str, err := csvtag.DumpToString(tab)
```
The csv file written:
```csv
name,ID,number
some name,1,42.5
```
