To-do lists

ReSharper provides an easy way to track tasks and technical debt in your code — code items (comments, string literals, or identifiers) matching a specific pattern can be easily located in the editor as well as in the whole solution using the To-do Explorer window.

ReSharper: To-do explorer

To-do items are highlighted in the editor and on the marker bar according to their types (Edit, Normal, Question, Warning, Error). Colors are configurable on the Environment | Fonts and Colors page of Visual Studio options:

To-do patterns

By default, ReSharper provides three predefined patterns for commonly used To-do items of the following types:

  • A comment containing TODO - Normal

  • A comment containing BUG - Error

  • A NotImplementedException in the code - Edit

You can also define your own patterns, so that you could quickly access your specific technical debt items in the To-do Explorer window.

Define a custom To-do pattern

  1. Open the Tools | To-do Explorer page of ReSharper options Alt+R, O.

  2. Click Add on the toolbar.

  3. Provide a title for your To-do pattern and specify a regular expression with keywords that you want to detect in comments. For example, (\W|^)(?<TAG>Refactor)(\W|$)(.*).

  4. Select where ReSharper should apply the expression to find the To-do items (comments, strings, and/or identifiers).

  5. Optionally, specify whether the pattern is case-sensitive.

  6. Select a type for the pattern to define how matched items will be colored in the editor and in the To-do Explorer window.

  7. Click OK to add this pattern to the list.

  8. You can also duplicate, edit or remove existing patterns.

  9. Click Save in the Options dialog to apply the modifications and let ReSharper choose where to save them, or save the modifications to a specific settings layer by choosing this layer from the Save To selector. For more information, see manage and share resharper settings.

Link To-do items to external URLs

In a To-do pattern, you can add a placeholder for items that will point to an external URL. This comes in particularly handy for issue trackers — you can use IDs of the issues in your comments, and ReSharper will let you open the corresponding issues in the browser or directly in the editor peek view.

Suppose your project is on GiHub and you want to add comments for GitHub issues in your code. All you have to do is create a custom To-do pattern for that:

  • Regular expression: (?<=\W|^)(?<TAG>GH \#(?<ISSUE_ID>\d+))(\W|$)(.*)

  • URL: https://github.com/<YOUR_PROJECT>/issues/${ISSUE_ID}

ReSharper. To-do pattern that recognizes GitHub issues

ReSharper will now treat GH #XX in your comments as links to the corresponding GitHub issues.

ReSharper. To-do link to GitHub issue from the comment

Besides Ctrl-clicking on these comments, you can also Ctrl+Shift-click to open the link in the editor peek preview. Both ways of navigating to the URLs are also available from the Alt+Enter menu.

To navigate between To-do items in the current file, use To-do marks on the marker bar.

Study To-do items in the whole solution

  1. Press Control+Alt+. or choose ReSharper | Windows | To-do Explorer from the main menu . Alternatively, you can press Control+Shift+A, start typing the command name in the popup, and then choose it there.

  2. In the To-do Explorer window that opens, click ThemedIcon.Down.Screen.(Gray).png or ThemedIcon.Up.Screen.(Gray).png to navigate to the next or previous item.

    To locate To-do items in the editor, double-click them .

  3. To study the source code of the selected item right in the window, click Show Preview ThemedIcon.PreviewToggle.Screen.(Gray).png on the toolbar. If necessary, you can locate the preview pane at the bottom or on the right.

Group and filter To-do items

By default, the To-Do Explorer lists to-do items based on project structure. If necessary, you can change grouping options using the Group by selector. You can disable grouping, group by tags, types, namespaces, directories, projects.

ReSharper: Grouping To-do items

Depending on the size and age of the codebase, there may be lots of To-do items. To focus on specific items, you can filter To-do items by pattern (for example, TODO or BUG) — just select the desired patterns in the Filter ThemedIcon.Filter.Screen.(Gray).png selector to display items matching the corresponding patterns and hide all others.

Allows you to show or hide To-do items in generated code. You can configure the list of files and regions containing generated code on the Code Inspection | Generated Code page of ReSharper options .

Filter

Use this list to select a filter to show items that pertain to the corresponding pattern only. By default, five filters are provided:

  • (all)

  • Todos

  • Notes

  • Bugs

  • Not Implemented

Group by

Use this list to select criteria for grouping To-do items. Several options are provided:

  • None - items are displayed as a plain list.

  • Types - items are grouped by containing types.

  • Namespaces - items are grouped by namespaces, which are displayed as a plain list, with nesting structure not taken into account.

  • Namespaces and Types - items are grouped by namespaces and, on a lower level, by classes where they are encountered.

  • Directories - items are grouped by directories where they are stored; directories are displayed as a plain list, with nesting structure not taken into account.

  • Files - items are grouped by their containing files.

  • Directories and Files - items are grouped by directories where they are stored and, on a lower level, by their containing files; directories are displayed as a plain list, with nesting structure not taken into account.

  • Projects - items are grouped by their containing projects.

  • Projects and Types - items are grouped by containing projects and, on a lower level, by types.

  • Projects and Directories - items are grouped by containing projects and, on a lower level, by directories; within a project, directories are displayed as a plain list, with nesting structure not taken into account.

  • Project Structure - items are grouped according to the physical structure of a project, with all nesting relationships represented.
