Interface definition language compiler with version reconciliation

One or more non-transitory machine readable media comprising program code for compiling an interface definition language program code, the program code to:

• in response to receipt of a compile command that indicates a target version and a target program language, determine which of a plurality of code sections in the interface definition language program code is governed by a compile directive that indicates a range of versions that encompasses the target version;
• disregard those of the plurality of code sections governed by a compile directive that indicates a range of versions that does not encompass the target version;
• determine whether changes between code sections that have not been disregarded and are governed by compile directives that indicate different ranges of versions cause a semantic error;
• provide the code sections that have not been disregarded for generation of an intermediate representation in response to a determination that the changes do not cause semantic errors;
• and
• associate a semantic error caused by a change between code sections with a corresponding expression or parameter in the code section of a later range of versions.

An apparatus comprising:

• a processor;
• and
• a machine readable medium comprising program code executable by the processor to cause the apparatus to,
• based on receipt of a compile command that indicates a target version and a target program language for an interface definition language program code that includes a plurality of code sections and a plurality of compile directives that indicate versions, select from a plurality of code sections a set of code section to compile, wherein selection is based, at least in part, on the target version and on the plurality of compile directives, wherein the program code to select comprises the program code executable by the processor to cause the apparatus to determine which of the plurality of compile directives indicates the target version or a range of versions that encompasses the target version;
• determine whether a change between a first of the set of code sections and a second of the set of code sections causes a semantic error, wherein the first code section is associated with a first of the plurality of compile directives that indicates a first range of versions and the second code section is associated with a second of the plurality of compile directives that indicates a second range of interface versions, wherein each of the first and second ranges of versions encompasses the target version;
• and
• provide the set of code sections for generation of an intermediate representation of the set of code sections in response to a determination that no semantic error is caused by a change among the set of code sections corresponding to different version ranges.
