Abstract
Systems and methods for configuration management through information and code injection at compile time. An example method comprises: receiving a source code comprising one or more references to a variable; receiving metadata associated with the source code, wherein the metadata specifies a range of values of the variable; and identifying, in view of the range of values of the variable, a reachable section of the source code.
Claims12
A method comprising:
- receiving, by a processing device, a source code comprising one or more references to a run-time variable;
- receiving metadata provided by a markup in the source code, wherein the metadata comprises a compiler-internal variable that specifies a run-time value of the run-time variable, wherein the run-time value determines an outcome of evaluating a conditional expression referencing the run-time variable;
- identifying, at compile time, by evaluating the conditional expression based on the run-time value of the run-time variable, a reachable section of the source code;
- injecting the run-time value of the run-time variable into the source code;
- and
- compiling the reachable section of the source code.

A system comprising:
- a memory;
- a processing device operatively coupled to the memory, the processing device to:
- receive a source code comprising one or more references to a run-time variable;
- receive metadata provided by a markup in the source code, wherein the metadata comprises a compiler-internal variable that specifies a run-time value of the run-time variable, wherein the run-time value determines an outcome of evaluating a conditional expression referencing the run-time variable;
- identify, at compile time, by evaluating the conditional expression based on the run-time value of the run-time variable, a reachable section of the source code;
- inject the run-time value of the run-time variable into the source code;
- and
- compile the reachable section of the source code.
5 more elements
A non-transitory computer-readable storage medium comprising executable instructions that, when executed by a processing device, cause the processing device to:
- receive a source code comprising one or more references to a run-time variable;
- receive metadata provided by a markup in the source code, wherein the metadata comprises a compiler-internal variable that specifies a run-time value of the run-time variable, wherein the run-time value determines an outcome of evaluating a conditional expression referencing the run-time variable;
- identify, at compile time, by evaluating the conditional expression based on the run-time value of the run-time variable, a reachable section of the source code;
- inject the run-time value of the run-time variable into the source code;
- and
- compile the reachable section of the source code.
