1. A method for generating code executable in a target processing environment, the method comprising: processing a first command line by a first processor, wherein the first command line is generated by an integrated development environment (IDE), said processing the first command line executes a command line tool as a step to produce code executable by the target processing environment and generates one or more output entries; comparing the one or more output entries to a concatenated regular expression to determine whether the one or more output entries correspond to a first class of error identifiers, wherein the concatenated regular expression comprises a complete set of trigger expressions corresponding to the first class of error identifiers; if the one or more output entries correspond to the first class of error identifiers, then determining an error identifier of the first class of error identifiers corresponding to the one or more output entries, and providing information corresponding to the error identifier and the one or more output entries to the IDE; and if the one or more output entries do not correspond to the first class of error identifiers and if the one or more output entries correspond to one of a second class of error identifiers, then providing information corresponding to the one of the second class of error identifiers and the one or more output entries to the IDE.
