Abstract

A source code file is generated in accordance with a first coding format employed by a first user. In response to a request for the generated source code file from a second user employing a different coding format, the generated source code file is transformed to the different coding format employed by the second user, and the transformed source code file is presented to the second user in the different coding format.

Claims

1. A method of transforming a source code file for different coding formats comprising:

generating a source code file in accordance with a first coding format employed by a first user, wherein generating the source code file comprises;

converting the source code file to a preference-neutral source code file by stripping the first coding format from the source code file;

parsing the preference-neutral source code file into a first plurality of elements of a first tree structure; and

storing the first tree structure in a repository;

in response to a request for the generated source code file from a second user employing a different coding format;

transforming the generated source code file to the different coding format employed by the second user;

presenting the transformed source code file to the second user in the different coding format;

receiving changes by the second user to the source code file in the different coding format;

converting the source code file in the different coding format to a second preference-neutral source code file by stripping the different coding format from the source code file;

parsing the second preference-neutral source code file into a second plurality of elements of a second tree structure;

retrieving the first tree structure from the repository and comparing each of the first plurality of elements of the first tree structure to the second plurality of elements of the second tree structure to identify substantive modifications in the second plurality of elements, wherein a substantive modification is identified when comparing an element of the first plurality of elements to a corresponding element of the second plurality of elements indicates a difference in content between the compared elements, and wherein the first and second tree structures include a document object model; and

applying the substantive modifications to the first tree structure to modify the source code file.

2. The method of claim 1, wherein:

generating the source code file includes converting the generated source code file to a format of the repository and storing the converted source code file in the repository; and

transforming the generated source code file includes retrieving the converted source code file from the repository and transforming the converted source code file to the different coding format employed by the second user.

3. The method of claim 1, further comprising:

generating a second source code file in each of one or more different coding formats employed by one or more corresponding users; and

transforming the generated second source code file for the second user by retrieving the second source code file corresponding to the different coding format employed by the second user.

4. A system for transforming a source code file for different coding formats comprising:

a computer system including at least one processor configured to;

generate a source code file in accordance with a first coding format employed by a first user, wherein generating the source code file comprises;

converting the source code file to a preference-neutral source code file by stripping the first coding format from the source code file;

parsing the preference-neutral source code file into a first plurality of elements of a first tree structure; and

storing the first tree structure in a repository;

in response to a request for the generated source code file from a second user employing a different coding format;

transform the generated source code file to the different coding format employed by the second user;

present the transformed source code file to the second user in the different coding format;

receive changes by the second user to the source code file in the different coding format;

convert the source code file in the different coding format to a second preference-neutral source code file by stripping the different coding format from the source code file;

parse the second preference-neutral source code file into a second plurality of elements of a second tree structure;

retrieve the first tree structure from the repository and compare each of the first plurality of elements of the first tree structure to the second plurality of elements of the second tree structure to identify substantive modifications in the second plurality of elements, wherein a substantive modification is identified when comparing an element of the first plurality of elements to a corresponding element of the second plurality of elements indicates a difference in content between the compared elements, and wherein the first and second tree structures include a document object model; and

apply the substantive modifications to the first tree structure to modify the source code file.

5. The system of claim 4, wherein:

generating the source code file includes converting the generated source code file to a format of the repository and storing the converted source code file in the repository; and

transforming the generated source code file includes retrieving the converted source code file from the repository and transforming the converted source code file to the different coding format employed by the second user.

6. The system of claim 4, wherein the at least one processor is further configured to:

generate a second source code file in each of one or more different coding formats employed by one or more corresponding users; and

transform the generated second source code file for the second user by retrieving the second source code file corresponding to the different coding format employed by the second user.

7. A computer program product for transforming a source code file for different coding formats comprising:

a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code, when executed by a processor, causes the processor to;

generate a source code file in accordance with a first coding format employed by a first user, wherein generating the source code file further comprises;

converting the source code file to a preference-neutral source code file by stripping the first coding format from the source code file;

parsing the preference-neutral source code file into a first plurality of elements of a first tree structure; and

storing the first tree structure in a repository;

in response to a request for the generated source code file from a second user employing a different coding format;

transform the generated source code file to the different coding format employed by the second user;

present the transformed source code file to the second user in the different coding format;

receive changes by the second user to the source code file in the different coding format;

convert the source code file in the different coding format to a second preference-neutral source code file by stripping the different coding format from the source code file;

parse the second preference-neutral source code file into a second plurality of elements of a second tree structure;

retrieve the first tree structure from the repository and compare each of the first plurality of elements of the first tree structure to the second plurality of elements of the second tree structure to identify substantive modifications in the second plurality of elements, wherein a substantive modification is identified when comparing an element of the first plurality of elements to a corresponding element of the second plurality of elements indicates a difference in content between the compared elements, and wherein the first and second tree structures include a document object model; and

apply the substantive modifications to the first tree structure to modify the source code file.

8. The computer program product of claim 7, wherein:

generating the source code file includes converting the generated source code file to a format of the repository and storing the converted source code file in the repository; and

transforming the generated source code file includes retrieving the converted source code file from the repository and transforming the converted source code file to the different coding format employed by the second user.
