# Termtables
[![Build Status](https://travis-ci.org/apcera/termtables.svg?branch=master)](https://travis-ci.org/apcera/termtables)
A [Go](http://golang.org) port of the Ruby library [terminal-tables](https://github.com/visionmedia/terminal-table) for
fast and simple ASCII table generation.
## Installation
```bash
go get github.com/apcera/termtables
```
## Go Style Documentation
[http://godoc.org/github.com/apcera/termtables](http://godoc.org/github.com/apcera/termtables)
## APC Command Line usage
`--markdown` — output a markdown table, e.g. `apc app list --markdown`
`--html` — output an html table, e.g. `apc app list --html`
`--ascii` — output an ascii table, e.g. `apc app list --ascii`
## Basic Usage
```go
package main
import (
"fmt"
"github.com/apcera/termtables"
)
func main() {
table := termtables.CreateTable()
table.AddHeaders("Name", "Age")
table.AddRow("John", "30")
table.AddRow("Sam", 18)
table.AddRow("Julie", 20.14)
fmt.Println(table.Render())
}
```
Result:
```
+-------+-------+
| Name | Age |
+-------+-------+
| John | 30 |
| Sam | 18 |
| Julie | 20.14 |
+-------+-------+
```
## Advanced Usage
The package function-call `EnableUTF8()` will cause any tables created after
that point to use Unicode box-drawing characters for the table lines.
Calling `EnableUTF8PerLocale()` uses the C library's locale functionality to
determine if the current locale environment variables say that the current
character map is UTF-8. If, and only if, so, then `EnableUTF8()` will be
called.
Calling `SetModeHTML(true)` will cause any tables created after that point
to be emitted in HTML, while `SetModeMarkdown(true)` will trigger Markdown.
Neither should result in changes to later API to get the different results;
the primary intended use-case is extracting the same table, but for
documentation.
The table method `.AddSeparator()` inserts a rule line in the output. This
only applies in normal terminal output mode.
The table method `.AddTitle()` adds a title to the table; in terminal output,
this is an initial row; in HTML, it's a caption. In Markdown, it's a line of
text before the table, prefixed by `Table: `.
The table method `.SetAlign()` takes an alignment and a column number
(indexing starts at 1) and changes all _current_ cells in that column to have
the given alignment. It does not change the alignment of cells added to the
table after this call. Alignment is only stored on a per-cell basis.
## Known Issues
Normal output:
* `.SetAlign()` does not affect headers.
Markdown output mode:
* When emitting Markdown, the column markers are not re-flowed if a vertical
bar is an element of a cell, causing an escape to take place; since Markdown
is often converted to HTML, this only affects text viewing.
* A title in Markdown is not escaped against all possible forms of Markdown
markup (to avoid adding a dependency upon a Markdown library, as supported
syntax can vary).
* Markdown requires headers, so a dummy header will be inserted if needed.
* Table alignment is not reflected in Markdown output.
