Tabwriter | What Is Tabwriter

Tabwriter is a feature-rich tab stop program for HTML that provides a flexible, yet user-friendly environment for building and maintaining Web sites. You can use it for both Elastic and tabstops, and choose from multiple alignment options. Plus, you can take advantage of its easy-to-use interface, which includes a powerful tab editor.


Go’s text and tabwriter package has a lot to offer. This package is especially handy in command line applications that have relational data. Its many functions include a built-in filter and a simple but effective tab writing tool. Although it’s been around for a while, it’s only recently that it has received a facelift.

The tabwriter’s tagging algorithm provides an efficient way to mark up data in a format that’s easy to read. This is done by detecting the start of a new line and wrapping it into a new column. In doing so, the tabwriter package has managed to produce some of the most elegant output in Go.

The tabwriter package also has a slew of other nifty tricks up its sleeve. For instance, it provides a simple way to write output in a column whose tabs are automatically aligned. A column containing tabs on one side and zero on the other appears as a single column, which is handy for things like spreadsheets. Other notable features of the package include the gimmick of elastic tabstops, which essentially allows you to resize the tabs to fit your needs. With its help, you can write in a column that’s as long as you’d like.

Several other goodies are included in the package, including a clever filter that turns tabs on and off with the click of a button. In the end, it’s clear that the Go text and tabwriter package is the best choice when compared to other options on the market. Whether you’re looking for table-like output or a more traditional command line interface, the tabwriter package is worth a look. Hopefully, the package will remain an active and useful addition to Go’s libraries for years to come.

Elastic tabstops


Elastic tabstops for tabwriter are useful in creating and displaying table-based data. The mechanism is based on a simple idea. It aligns the text to the left, right, or center. In order to do this, the tab stop must be adjust based on the character it is aligning to. This can be don by using a new line or by adjusting the length of the adjacent tab-delimited line segments.

If a line of text contains a vertical tab character, the tab stops extend it to the left. Similarly, if a column of cells begins with a vertical tab, the block of cells runs vertically from the first to the last cell. However, the tab stops do not terminate the cell. Instead, the tab delimits the column. Unlike spaces, tabs are not automatically detected by IDEs, so they need to be manually set.

Some popular IDEs have already implemented the elastic tabstops algorithm. Some popular text editors have also supported the feature. For example, Elastic Notepad, Elastic Browser, and Go’s tabwriter package.

Key Difference Between Tabs And Spaces

A key difference between tabs and spaces is that the former require a rewrite of the code. For instance, if the editor saves files with tabs converted to spaces, the source diffs will look bad. Consequently, a lot of programmers will not want to use tabs.

If you do not use tabs, you may have problems aligning your text. To remedy this, you can try a more complicated context-sensitive approach. Or you can simply lay out your code in a way that ensures your text lines up.

While the mechanism for implementing elastic tabstops is not completely perfect, it is quite simple. And it can solve the holy war between spaces and tabs. Compared to the mod-N model, it is conceptually simpler. Also, its impact is minimal. But, it requires more computational work. Ultimately, it is a matter of taste.

One reason that the concept has not caught on is that most people do not need or care about it. Moreover, the tabs vs spaces debate has been a heated one for decades. People on either side of the argument would likely dislike elastic tabstops. Nevertheless, it could be helpful for people to agree on a more workable solution.

Alignment options

Alignment options for tabwriter are numerous. In fact, it isn’t a bad idea to check out the features of the tabwriter package in addition to the standard Go syntax. For example, there’s the TabWriter crate, which contains a command line version of the package. If you’re a developer, it’s a good idea to familiarize yourself with the various ways to use the package.


The tabwriter is one of those packages that you can’t just add and forget. It has to be call to flush out data and produce a clean output. You can also specify what kind of output you want – tabs or text – when you’re writing a document. This makes tabwriter a versatile tool.

The tabwriter also enables you to wrap the package in a container, in which case the enclosing structure can have Escape characters (and possibly tabs). Using the crate, you’re able to do things like recursively iterate through all of your tabs and print a page with no breaks. A lot of this is down to the fact that the tabwriter uses a lightweight python script. But there’s more to it than that. The package also has a handful of other niceties, like elastic tabstops and a wysiwyg editor.

The Go text/tabwriter package is a powerful and robust suite for the command line. It’s a great addition to the go library, especially for those of you writing command line applications that deal with relational data. To get start with the package, you’ll want to check out the official documentation for more details. Ultimately, the tabwriter package is a great way to convert tabstopped text into aligned text. Using the package will ensure that your documents are easy to read.
