Patent Application
20140075364
Developers frequently navigate to the same sections of code in projects in an integrated development environment (IDE). These sections may be continuously edited as the developers refine key features, for example. Users must move between files and scroll through lines of code to find the functions of interest or to review previous edits. For large projects with multiple code files and very many lines of code, it can be time consuming for users to move among a few frequently visited sections of code.
When the user returns to a previously edited section of code, they must recall from memory or refer to notes to remember what changes were previously made in that code section. For a much revised section of code and for very large projects, it can be difficult for users to keep track of all the changes that were previously entered.
Similar problems arise in word processing, project management, database, and other programs. Certain sections of large document collections, projects, or databases may be visited and edited more frequently than others, but these often-visited sections may be spread out among the relevant files.
Previous solutions allow users to use a search tool to find selected sections of a file or document. However, the search must be run each time to create a list of possible destinations. Additionally, the searches do not include information regarding past edits to the code or text. Some applications provide a simple list of previous edit actions that indicate, for example, the occurrence of deletions, insertions, moves, font changes, and the like. However, these lists do not show a chronological list of the user's edits or the user's navigation within the document or file.
This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter.
A user's repeated navigations within a code file or text document may be predicted based on the user's prior navigations. Users are more likely to return to functions or methods they have edited in the past or in which they have spent a significant amount of time but not editing (i.e., dwelling). In one embodiment, a code stream provides a historical view of the user's changes to program code and related actions. The user can display the code stream view on the screen concurrently with the code for reference, navigation, editing, sharing, and to aid in interruption recovery.
The code stream automatically constructs a list of visited code segments based on user changes to the code or navigation within the code. The code stream is an activity history that is constructed based on analysis of user navigation behavior, such as specific edits to the code or dwelling in a section of the code. The user has the ability to undo changes in the code in a non-linear fashion by individually reversing changes from the history listed in the code stream.
The code stream can be saved, persisted to a file and shared with other users. The code stream integrates with a suspend/resume mechanism to help resume tasks more efficiently because the code stream allows a user to see what happened with the task prior to its suspension. The code stream includes a deep provenance of the code by saving the location and differences in previous versions of the code. Changes to the same function are grouped into one history point in the code stream.
Additionally, users can explicitly include or exclude individual items in the code stream view. External information, such as tasks, emails, instant messages, web pages, debug data, variable values, and the like, can be tagged into the code stream.
In other embodiments, the code stream may represent content of documents, projects, databases or other files.
To further clarify the above and other advantages and features of embodiments of the present invention, a more particular description of embodiments of the present invention will be rendered by reference to the appended drawings. It is appreciated that these drawings depict only typical embodiments of the invention and are therefore not to be considered limiting of its scope. The invention will be described and explained with additional specificity and detail through the use of the accompanying drawings in which:
A code stream is automatically constructed based on user behavior while viewing, creating, or editing code in a file. User activity is monitored and a degree-of-interest model is created to determine the set of content that is most relevant to the user. For example, when a user creates new code, edits existing code, or spends time looking (i.e., dwells) at specific code, that code is identified as being of higher interest to the user. It is more likely that the user will return to this code for additional revisions or reference compared to other code.
Users may further extend the code stream by manually tagging content into the code stream. These items may include code (e.g., functions, methods, etc.) that has not been automatically added to the code stream or external material, such as tasks, emails, instant messages, debug data, and the like.
The user may also tag external information into the code stream through an extensible provenance framework. For example, in one embodiment, a textual representation cache is saved for each code stream item along with a cache timestamp, as well as a history tag type, a timestamp, and an XML blob comprising the location of the information. A plug-in architecture allows this information to be resolved and displayed on the screen.
The code stream typically presents a historical view showing the most recently accessed code at the top of a list. The user can select specific items in the code stream to undo. The user is not required to undo later edits in order to undo the selected code. This allows the user to undo their changes in a non-linear manner.
The code stream can be saved and persisted to a file. This allows the code stream to be shared with other users or to be recalled by the user at later time. The persistence file contains complete details of the code stream, such as the fully-qualified name of the methods/functions/classes, the start/end locations (offsets) in the file, the fully qualified path to the file, as well as the actual contents of the fragment. Additionally, a baseline version of the file and branch information may be stored. A fully qualified version control path may also be stored. This allows the code stream to reliably re-open on other computers. If the user does not have the content, then a static cache of the contents may be shown. If the user has the wrong version of the code files, a warning regarding version error may be shown and the cached content is shown. Otherwise, the actual live file content is shown if available. The redundant information comprises deep provenance.
The code stream allows for suspend/resume integration, which allows the user to suspend their work and resume it later. The code stream allows users to resume the task more efficiently by reading the available history information.
Code changes are displayed in the code stream in chronological order with relative timestamp information for each entry. The system groups multiple edits in the same function into a single entry, showing this entry at the timestamp of the most recent edit in that function. For non-functional edits, the system displays just the edited lines and provenance information.
The user has also opened another task 308, which is added to the code stream timeline with the appropriate description and timestamp.
The user's edits to Function C 309 have also been added to the code stream timeline. In particular, Function C originally had five lines of code and has now been edited to have six lines of code. The new code is shown in editor window 301. Entry 309 in task history 302 also shows the changes 310 to the code. The edited code 310 for Function C may be assigned a font or highlighting that indicates how it was edited by the user. For example, inserted code may be underlined, deleted code may be shown as strikeout text and moved or copied code may be highlighted in some other way. A timestamp 311 is also applied to this new task and the timestamps for the previous entries have been updated.
An Instant Message 404 and Sharing Session 405 have also been added to the code stream along with relevant details and timestamps. These entries may have been added manually by the user or automatically added by the IDE.
The task history 402 also shows that the user has dwelled in two functions—Function D (406) and Function E (407). Dwelling may include, for example, opening or selecting the function in the editor window 401, copying the function or lines of code, making unsaved edits in the function, or otherwise indicating a user interest in the function. The icons 408, 409 indicate that other details are available for dwelling entries 406 and 407, but the details are collapsed out of view to simplify the display. On the other hand, icon 410 for Function C (309) may indicate that this entry has been expanded to show the relevant details. The user has flagged (411) the entry for Function B (407), which may be used, for example, to indicate that the user should return to this function or to highlight the function to a co-worker.
The previous entry for Function C was listed between the Debug Session and Task 2 entries in task history window 602. This entry has been removed because Function C is now the current activity at the top of the list. In other embodiments, the previous entries for the same function or task may remain in their original position to display a task-by-task list of the user's previous activity in the project.
Although the example shown in
The user's activity history, such as the code stream shown in the task history windows of
In step 705, user instructions are received indicating selected items to add to the activity history. These user-selected are added to the activity history and displayed to the user. The selected items may be associated with other applications running on the same or a different computer. The selected items may be tasks, email messages, instant messages, web pages, and debugger variable values.
When a user selection of an item listed in the activity history is received, the content related to the user-selected item is displayed. The user-selected item may be, for example, a previous edit to the software code. The activity history may be saved in a format that can be accessed by another user.
The activity history may also be updated to remove user-selected items. A user may identify a previous action in the activity history and designate that previous action to be reversed. The previous action may be an edit to the code that occurred at a designated time. The code is returned to a prior state that existed at the designated time without undoing other code edits that occurred at other times.
The activity history may be saved in a sharable format that can be accessed by other users to determine what actions were performed on the code.
It will be understood that steps 701-705 of the process illustrated in
The invention may be described in the general context of computer-executable instructions, such as program modules, being executed by a computer. Generally, program modules include routines, programs, objects, components, data structures, and so forth, which perform particular tasks or implement particular abstract data types. The invention may also be practiced in distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules may be located in local and/or remote computer storage media including memory storage devices.
With reference to
The computer 900 typically includes a variety of computer-readable media 904. Computer-readable media 904 may be any available media that can be accessed by the computer 900 and includes both volatile and nonvolatile media, and removable and non-removable media, but excludes propagated signals. By way of example, and not limitation, computer-readable media 904 may comprise computer storage media and communication media. Computer storage media includes volatile and nonvolatile, removable and non-removable media implemented in any method or technology for storage of information such as computer-readable instructions, data structures, program modules or other data.
