This is a Golang library to interactively rearrange a text data on a terminal.

When a text data is rearranged, there are many applications for automatically sorting text data. But there are a little CLI applications for manually rearranging it using. Furthermore, I just had to create an application for manually and interactively rearranging data. So I created this.

• Data can be interactively rearranged on your terminal as a CLI tool.
• Output rearranged data as []string.
• Retrieve selected values and select history.

You can install this using go get as follows.

$ go get -u github.com/tanaikech/go-rearrange

This library uses termbox-go.

result, history, err := rearrange.Do(data, step, selectmode, indexmode)

• data ([]string) : Data for rearranging. This has to be 1 dimensional string array. Each element is rearranged.
• step (int) : Number of steps for PageUp, PageDown.
• selectmode (bool) : If this is true, it's used as select mode. In this case, users only select a value. The selected values are output.
• indexmode (bool) : If this is true, the rearranged result is output as the change of index for the source data. For example, if the source data and rearranged data are ["a", "b", "c"] and ["c", "b", "a"], respectively. The output will become [2, 1, 0].

• result ([]string) : Rearranged data. Data is returned as []string.
• history ([]string) : History of rearranged data. When the data is rearranged, the selected data is saved as a history like [{Index:9 Value:sample10} {Index:1 Value:sample1}].
• err (error) : Error.

Use up, down, page up, page down, home, end, enter, back space, Ctrl + c and escape keys.

• gorearrange : This is a CLI tool to interactively rearrange a text data on a terminal.
• ggsrun : This was used for rearranging scripts in a GAS project.

• v1.0.0 (October 15, 2017)

  Initial release.

• v1.0.1 (October 16, 2017)

  • As one of outputs, indexmode (bool) was added. If this is true, the rearranged result is output as the change of index for the source data. For example, if the source data and rearranged data are ["a", "b", "c"] and ["c", "b", "a"], respectively. The output will become [2, 1, 0].

• v1.0.2 (October 18, 2017)

  • From this version, data included multi-bytes characters can be used. At Linux, it works fine. At Windows DOS, rearranging and selecting data can be done. But the displayed data is shifted. Although this may be a bug of termbox-go, I don't know the reason. I'm sorry. On the other hand, data with only single-byte characters works fine. About MAC, I don't have it. If someone can confirm and tell me it, I'm glad.
