Utility functions to manipulate text with or without ANSI escape sequences. Most of the functions available are used in one or more of the other packages here.
- Align text horizontally or vertically
- Colorize text
- Cursor Movement
- Format text (convert case)
- String Manipulation (Pad, RepeatAndTrim, RuneCount, Trim, etc.)
- Transform text (UnixTime to human-readable-time, pretty-JSON, etc.)
- Wrap text
The unit-tests for each of the above show how these can be used. There GoDoc should also have examples for all the available functions.

To make go-pretty completely compatible with go mod, versions v6.0.0 and
above will include changes that are known to break dep support. As far as I
can tell, dep is looking for funding right now and is not being actively
developed or maintained and has an interoperability issue with how go mod
deals with package versioning.
If you want to continue to use dep, versions v5.1.x and below should
continue to work. If dep maintainers can merge the code proposed in
PR#1963, it should make v6.0.0 and
above usable too. Given that the PR has not been merged since July 2018, I am
not too hopeful. 😞
To use v6.0.0 (or newer version) of this library, you'd have to modify the
import paths from something like:
"github.com/jedib0t/go-pretty/list"
"github.com/jedib0t/go-pretty/progress"
"github.com/jedib0t/go-pretty/table"
"github.com/jedib0t/go-pretty/text"to:
"github.com/jedib0t/go-pretty/v6/list"
"github.com/jedib0t/go-pretty/v6/progress"
"github.com/jedib0t/go-pretty/v6/table"
"github.com/jedib0t/go-pretty/v6/text"I'd recommend you fire up your favorite IDE and do a mass search and replace for
all occurrences of jedib0t/go-pretty/ to jedib0t/go-pretty/v6/. If you are
on a system with access to find, grep, xargs and sed, you could just run
the following from within your code folder to do the same:
find . -type f -name "*.go" | grep -v vendor | xargs sed -i 's/jedib0t\/go-pretty\//jedib0t\/go-pretty\/v6\//'g
