Introduction

Org Mode is a powerful tool for note-taking and organization in Emacs. One of its features is the column mode, which allows users to display information in a table format. However, setting the default columns for each file can be a tedious task, especially when working with multiple files. In this article, we will explore how to set default columns in Org Column Mode into the init file, eliminating the need to repeat the settings for each file.

Understanding Org Column Mode

Org Column Mode is a feature in Org Mode that allows users to display information in a table format. It is useful for organizing tasks, notes, and other information in a structured way. The column mode can be customized to display different information, such as item names, tags, priorities, and deadlines.

Setting Default Columns in a File

To set default columns in a file, you can use the #+COLUMNS keyword followed by the desired column settings. For example:

#+COLUMNS: %45ITEM %TAGS %PRIORITY %TODO %CLOSED %SCHEDULED

This sets the default columns to display the item name (up to 45 characters), tags, priority, TODO state, closed state, and scheduled state.

Setting Default Columns in the Init File

However, setting the default columns in each file can be repetitive and time-consuming. A better approach is to set the default columns in the init file, which is a file that contains Emacs configuration settings. To set the default columns in the init file, you can add the following code:

(setq org-columns-default-format "%45ITEM %TAGS %PRIORITY %TODO %CLOSED %SCHEDULED")

This sets the default columns to display the item name (up to 45 characters), tags, priority, TODO state, closed state, and scheduled state.

Benefits of Setting Default Columns in the Init File

Setting default columns in the init file has several benefits:

Convenience: You don't need to repeat the settings for each file.

Efficiency: You can focus on writing content without worrying about column settings.

Customizing Column Settings

Org Column Mode allows you to customize column settings to suit your needs. You can add or remove columns, change the width of columns, and even add custom columns. For example, you can add a column to display the creation date of each item:

(setq org-columns-default-format "%45ITEM %TAGS %PRIORITY %TODO %CLOSED %SCHEDULED %CREATED")

This adds a new column to display the creation date of each item.
