TXL

TXL is an acronym used for several distinct entities. The two most widely recognized are Berlin Tegel Airport, for which TXL is the IATA airport code (ICAO: EDDT), and the Tree Transformation Language, a programming language and system for source-code transformation.

Berlin Tegel Airport (Flughafen Berlin-Tegel) is located in the northwestern part of Berlin, Germany. It opened in 1948 and served domestic and international traffic for many decades. Following the opening of Berlin Brandenburg Airport (BER), scheduled commercial passenger flights at TXL ceased in 2020. The airport site has since seen reduced commercial activity and is the subject of redevelopment planning within Berlin’s post-closure strategy.

TXL (Tree Transformation Language) is a high-level, rule-based language and environment used to implement source-to-source transformations. It operates on tree representations of program syntax, using pattern matching and rewrite rules to express transformations. TXL has been employed in compiler construction, software modernization, refactoring, and program analysis, and it has influenced the design of later transformation tools in both academic and industrial contexts.

Other uses of the TXL acronym exist in various domains, including organizations and projects. Context is required to determine the intended meaning in a given instance.
