OPTIMIZING ERROR PARSING IN AN INTEGRATED DEVELOPMENT ENVIRONMENT

A system to enable an integrated development environment to efficiently parse error expressions generated by tools used to generate processing environment-specific executable code, where the tools are external to the integrated development environment, is provided. The system groups error parsers configured to parse the error expressions into two groups: error parsers that handle output from a tool using a single output line of regular expression, and error parsers that require something more than a single output line of regular expression to determine the nature of an error. Embodiments of the system can determine whether a particular output regular expression should be analyzed by a selected set of the error parsers by comparing the output regular expression against a concatenated list of all the regular expressions corresponding to those error parsers that handle output from the tool using a single output line of regular expression.
