'''Code completion''' is an [[Autocomplete|autocompletion]] feature in many [[integrated development environment]]s (IDEs) that speeds up the process of coding applications by fixing common mistakes and suggesting lines of code. This usually happens through popups while typing, querying parameters of functions, and query hints related to syntax errors. Modern code completion software typically uses [[generative artificial intelligence]] systems to predict lines of code{{Citation needed|date=May 2025}}. Code completion and related tools serve as documentation and disambiguation for [[variable (programming)|variable]] names, [[Subroutine|function]]s, and [[Method (computer science)|method]]s, using [[Static program analysis|static analysis]].<ref>{{Cite book |title= 2008 23rd IEEE/ACM International Conference on Automated Software Engineering|chapter=How Program History Can Improve Code Completion |date=2008 |doi=10.1109/ASE.2008.42 |last1=Robbes |first1=Romain |last2=Lanza |first2=Michele |pages=317–326 |isbn=978-1-4244-2187-9 |s2cid=2093640 }}</ref><ref>{{Cite web |date=2021-05-28 |title=Code Completion, Episode 1: Scenarios and Requirements |url=https://blog.jetbrains.com/blog/2021/05/28/code-completion-episode-1-scenarios-and-requirements/ |access-date=2023-11-17 |website=The JetBrains Blog |language=en-US}}</ref>
