Abstract

A software development environment receives an input string from a user, and searches for the input string in a plurality of program code files. The system then displays a result of the scope of the search on a viewport of a display unit, wherein the search result includes miniature views of the program code files. In an embodiment, the search result on the viewport of the display unit includes equally-sized tiles. In another embodiment, the result on the viewport of the display unit includes a set of closely-packed blocks with a varying compression rate applied to the closely-packed blocks.

Claims

1. A system comprising:

a computer processor configured to;

receive an input string from a user;

search for the input string in a plurality of program code files in an integrated software development environment (IDE);

display a result on a viewport of a display unit, the result comprising miniature views of the program code files, wherein the result on the viewport of the display unit comprises equally-sized tiles, or the result on the viewport of the display unit comprises a set of blocks with a varying compression rate applied to the blocks, such that the blocks permit a fitting of a large amount of program code files on the viewport of the display unit;

display the set of blocks by placing an initial block at the center of the viewport of the display unit;

place a subsequent block to the left, right, below, or above the initial block, such that the subsequent block is placed a least distance from the center of the viewport of the display unit;

iteratively place a plurality of subsequent blocks such that each subsequent block is placed at the least distance from the center of the viewport of the display unit and such that each subsequent block does not overlap any other previously placed block;

apply an increasing compression rate to the set of blocks as the distance from the center of the viewport of the display unit increases; and

move the display of the blocks about the center of the viewport of the display unit, thereby increasing a size of a particular block as the particular block moves toward the center of the viewport of the display unit;

wherein the least distance is determined from the center of the subsequent block.

2. The system of claim 1, wherein the display of the equally-sized tiles includes a scrollbar;

and wherein the display of the blocks does not include a scrollbar.

3. The system of claim 1, wherein the computer processor is configured to define a search scope comprising one or more of program code files with a particular extension, program code files categorized in a certain project, program code files currently open in a workspace, program code files currently closed in the workspace, and all program code files in an entire workspace.

4. The system of claim 1, wherein the miniature views of the program code files are generated by traversing the program code files line by line.

5. The system of claim 1, wherein the computer processor is configured to calculate a number of columns and a compression factor for the equally-sized tiles based on a number of lines in the program code files;

and

wherein the computer processor is configured to calculate the number of columns and the compression rate independently for each of the program code files, such that each program code file comprises an independent number of columns for the equally-sized tiles associated with each independent program code file.

6. The system of claim 1, wherein the increasing compression rate is applied both vertically and horizontally to the set of blocks.

7. The system of claim 1, wherein the computer processor is configured to receive a selection of a single block from a user;

and

in response to the user selection, move the selected single block to the center of the viewport of the display unit.

8. The system of claim 1, wherein the computer processor is configured to zoom-in and zoom-out the display of the blocks with a non-affine transformation to the viewport of the display unit.

9. The system of claim 1, wherein the computer processor is configured to receive input from a user selecting a particular equally-sized tile or a particular block;

and

to display an enlarged view of the particular equally-sized tile or the particular block in a second viewport of the display unit, thereby generating a code preview of the particular equally-sized tile or the particular block.

10. The system of claim 1, wherein the computer processor is configured to order the search of the programs code files as a function of one or more of currently opened program code files and when the currently opened program files were opened, program code files that have been changed or saved, a total amount of time that each particular program code file has been opened over a defined time period, and a number of lines in each particular program code file.

11. A non-transitory computer readable medium comprising instructions that when executed by a processor execute a process comprising:

receiving an input string from a user;

searching for the input string in a plurality of program code files in an integrated software development environment (IDE);

displaying a result on a viewport of a display unit, the result comprising miniature views of the program code files, wherein the result on the viewport of the display unit comprises equally-sized tiles, or the result on the viewport of the display unit comprises a set of blocks with a varying compression rate applied to the blocks, such that the blocks permit a fitting of a large amount of program code files on the viewport of the display unit;

displaying the set of blocks by placing an initial block at the center of the viewport of the display unit;

placing a subsequent block to the left, right, below, or above the initial block, wherein the subsequent block is placed a least distance from the center of the viewport of the display unit;

iteratively placing a plurality of subsequent blocks such that each subsequent block is placed at the least distance from the center of the viewport of the display unit and such that each subsequent block does not overlap any other previously placed block;

applying an increasing compression rate to the set of blocks as the distance from the center of the viewport of the display unit increases; and

moving the display of the blocks about the center of the viewport of the display unit, thereby increasing a size of a particular block as the particular block moves toward the center of the viewport of the display unit;

wherein the least distance is determined from the center of the subsequent block.

12. The non-transitory computer readable medium of claim 11, comprising instructions for zooming-in and zooming-out the display of the blocks with a non-affine transformation to the viewport of the display unit.

13. A method comprising:

receiving an input string from a user;

searching for the input string in a plurality of program code files;

displaying a result on a viewport of a display unit, the result comprising miniature views of the program code files, wherein the result on the viewport of the display unit comprises equally-sized tiles, or the result on the viewport of the display unit comprises a set of blocks with a varying compression rate applied to the blocks, such that the blocks permit a fitting of a large amount of program code files on the viewport of the display unit;

displaying the set of blocks by placing an initial block at the center of the viewport of the display unit; and

placing a subsequent block to the left, right, below, or above the initial block, wherein the subsequent block is placed a least distance from the center of the viewport of the display unit;

iteratively placing a plurality of subsequent blocks such that each subsequent block is placed at the least distance from the center of the viewport of the display unit and such that each subsequent block does not overlap any other previously placed block;

applying an increasing compression rate to the set of blocks as the distance from the center of the viewport of the display unit increases; and

moving the display of the blocks about the center of the viewport of the display unit, thereby increasing a size of a particular block as the particular block moves toward the center of the viewport of the display unit;

wherein the least distance is determined from the center of the subsequent block.

14. The method of claim 13, comprising receiving a selection of a single block from a user;

and

in response to the user selection, move the selected single block to the center of the viewport of the display unit.

15. The method of claim 13, comprising ordering the search of the programs code files as a function of one or more of currently opened program code files and when the currently opened program files were opened, program code files that have been changed or saved, a total amount of time that each particular program code file has been opened over a defined time period, and a number of lines in each particular program code file.
