Abstract

A text completion system is described herein that completes text at a tag and/or attribute level based on a syntactic understanding of software program code. The system includes sets of elements and associated attribute-value pairs that represent interesting, common, and repeated patterns. As a user is editing a web page or other document in an editing tool that implements the system, the user can retrieve, select, and insert these patterns using simple commands. The system receives a selected pattern from the user, and inserts target text associated with the pattern. In addition, users can fill in instance-specific data within the larger pattern to allow a single pattern to cover several common and closely related scenarios. Thus, the text completion system increases user productivity by providing more intelligent text completion through a syntactic understanding of the language in which a document is written.

Claims

1. A computer-implemented method for providing text completion shortcuts within a document, the method comprising:

receiving a notification that an editing application has loaded a document, wherein the document is associated with a particular programming language;

scanning one or more stored patterns to identify a shortcut word or characters that trigger each pattern and the type of text represented by the pattern;

loading the identified shortcuts into a completion list of the editing application that specifies shortcuts that a user can type to insert target text of the one or more patterns;

for each shortcut in the completion list, determining whether target text of a pattern associated with the shortcut is valid at a current insertion position based on the programming language associated with the document; and

filtering the patterns in the completion list based on whether the pattern is valid at the current insertion point, wherein the preceding steps are performed by at least one processor.

2. The method of claim 1 wherein receiving a notification comprises registering for the notification and receiving the notification from the application in response to a user creating a new document or modifying an existing document.

3. The method of claim 1 wherein the type of text represented by the pattern determines whether the text corresponds to a markup element or attribute.

4. The method of claim 1 further comprising caching the results of scanning one or more stored patterns and using the cached results in response to a user request to insert a pattern.

5. The method of claim 1 wherein the completion list contains shortcuts for token-level completion and markup tag-level completion.

6. The method of claim 1 wherein filtering the patterns comprises accessing a previously cached list of patterns to determine the target text for each pattern.

7. A computer system for reducing the amount of text typed by a user to compose a document, the system comprising:

a processor and memory configured to execute software instructions;

a scan patterns component configured to load one or more stored patterns from a data store;

a load patterns component configured to receive enumerated patterns from the scan pattern component and load one or more shortcuts associated with each pattern into a collection of words or characters that a user can type to cause the system to insert additional text into the document;

a detect trigger component configured to determine that the user has invoked a pattern by selecting the pattern'"'"'s shortcut; and

an insert target component configured to insert target text of a pattern in response to the detect trigger component detecting that a user has invoked the pattern.

8. The system of claim 7 wherein the data store accessed by the scan patterns component includes one or more XML files, each XML file containing one or more pattern definitions.

9. The system of claim 7 wherein the data store contains information about each pattern including a name of the pattern, one or more shortcuts that a user can type to invoke the pattern, and target text to insert after the pattern is invoked.

10. The system of claim 7 wherein the scan patterns component is invoked by an editing application in response to a user opening a document and wherein the scan patterns component preloads available patterns into memory for quick access in response to a user typing a pattern shortcut.

11. The system of claim 7 wherein the patterns provided by the system through the load patterns component supplement other shortcuts already in the list provided by an editing application.

12. The system of claim 7 further comprising a filter patterns component configured to filter patterns presented to the user based on information about a current cursor position.

13. The system of claim 12 wherein the filter patterns component is further configured to filter patterns based on whether each pattern target is valid for a language of the document at the current cursor position.

14. The system of claim 12 wherein the filter patterns component is further configured to receive a notification from an editing application before the application displays available patterns to the user.

15. The system of claim 7 wherein the detect trigger component detects that the user has selected a trigger in response to the user typing the trigger and pressing a key.

16. The system of claim 7 wherein the insert target component is further configured to identify one or more wildcards in a pattern definition and fill in the one or more wildcards based on a current context under which the pattern is invoked.

17. The system of claim 7 further comprising a post-process target component configured to modify the inserted target text of the invoked pattern based on user preferences.

18. A computer-readable storage medium comprising instructions for controlling a computer system to complete text in a document, wherein the instructions, when executed, cause a processor to perform actions comprising:

receiving an indication that a user has selected a pattern that specifies target text to replace shortcut text entered by the user;

inserting the target text associated with the selected pattern into a displayed text buffer, wherein the displayed text buffer represents the contents of the document, and wherein the document is a markup language document;

post-processes the inserted text to conform to one or more preferences set by the user; and

highlighting one or more fields that the user can replace in the inserted text, wherein the highlighted fields represent one or more values in the inserted text that may change based on a particular use of the pattern.

19. The medium of claim 18 wherein receiving an indication that the user has selected the pattern comprises displaying a user interface to the user containing a list of available patterns and receiving a selection from the user of a pattern from the list.

20. The medium of claim 18 wherein inserting the target text comprises inserting an opening tag, closing tag, and at least one attribute of a markup language element.
