Mnar - Columnar Text Selection Tool
Posted by Al Sweigart in misc
Try out Mnar in your browser. The EditPlus text editor for Windows had a great feature called columnar select which let you select a rectangle of text, rather than a linear stream of characters. This has always been useful to me for small ASCII art projects of tabular data. I generated Mnar, an offline browser app that makes it easy to paste text and do columnar selection on it. Because it's an offline browser app, you can simply save the .html file and own it forever. GitHub repo

Because it's an offline browser app, you can simply save the .html file and own it forever. GitHub repo
