ANTLR(1)

✨ NAME ✨

Okay bestie, welcome to ANTLR(1) 🎀, the General Commands Manual entry that's about to become your new special interest 😭💖

ANTLR is short for ANother Tool for Language Recognition, and this is version 3 🦋

🌸 SYNOPSIS 🌸

antlr3 [args] file.g [ file2.g file3.g ...]

💅 DESCRIPTION 💅

Okay so ANTLR (ANother Tool for Language Recognition) is a parser generator, and it's literally iconic 👑 It's built for reading, processing, executing, or translating structured text or binary files. People use it all the time to build languages, tools, and frameworks, no cap 🔥 You give it a grammar, and it generates a parser that can build parse trees and walk them. Main character energy, fr fr ✨

Here are all the options, bestie. Don't skip any 🫶

• -o outputDir — tell ANTLR where to put ALL the output you generate 📂
• -fo outputDir — same vibe as -o, but it also forces even files with relative paths into that dir 💪
• -lib dir — tells ANTLR where to find your token files 🧚
• -depend — generates file dependencies 🔗
• -report — prints a report about the grammar(s) it processed 📝
• -print — prints the grammar without the actions 🙈
• -debug — generates a parser that emits debugging events 🐛
• -profile — generates a parser that computes profiling info ⏱️
• -trace — generates a recognizer that traces rule entry and exit 🕵️‍♀️
• -nfa — generates an NFA for each rule 🌈
• -dfa — generates a DFA for each decision point 💜
• -message-format name — picks the output style for messages 🎀
• -verbose — generates ANTLR's version and other extra info 📣
• -make — only builds if the generated files are older than the grammar, so no wasted work ♻️
• -version — prints the ANTLR version and then exits 🍓
• -language L — overrides the language grammar option, and generates L instead 🌍
• -X — shows the list of extended arguments 👀
• -Xgrtree — prints the grammar AST 🌳
• -Xdfa — prints the DFA as text 📄
• -Xnoprune — tests lookahead against EBNF block exit branches 🧐
• -Xnocollapse — collapses incident edges into DFA states 🫧
• -Xdbgconversion — dumps lots of info during NFA conversion 😵‍💫
• -Xconversiontimeout — use this to restrict NFA conversion exponentiality ⏳
• -Xmultithreaded — runs the analysis in 2 threads 🧵
• -Xnomergestopstates — do not merge stop states 🛑
• -Xdfaverbose — generates DFA states in DOT with NFA configs 🗺️
• -Xwatchconversion — prints a message for each NFA before it converts 👁️
• -XdbgST — puts tags at the start and stop of all templates in the output 🏷️
• -Xnfastates — for nondeterminisms, lists the NFA states for each path 🛤️
• -Xm m — max number of rule invocations during conversion, default [4] 🔢
• -Xmaxdfaedges m — max "comfortable" number of edges for a single DFA state, default [65534] 🕸️
• -Xmaxinlinedfastates m — max DFA states before a table gets used instead of inlining, default [60] 📊
• -Xmaxswitchcaselabels m — doesn't generate switch() statements for DFAs bigger than m, default [300] 🚫
• -Xminswitchalts m — doesn't generate switch() statements for DFAs smaller than m, default [3] 🙅‍♀️
• -Xsavelexer — doesn't delete the temporary lexers generated from combined grammars 💾
