Package: atoml
ATOML - Yet another style-preserving TOML library for PythonATOML is a1.0.0rc1-compliantTOMLlibrary.It includes a parser that preserves all comments, indentations, whitespace and internal element ordering, and makes them accessible and editable via an intuitive API.You can also create new TOML documents from scratch using the provided helpers.The name comes from the famous Japanese cartoon character鉄腕アトム(Atom).Implementation Change: Start from 1.0, ATOML is a fork oftomlkit v0.7.0with less bugs and inconsistency.UsageParsingATOML comes with a fast and style-preserving parser to help you access
the content of TOML files and strings.>>>fromatomlimportdumps>>>fromatomlimportparse# you can also use loads>>>content="""[table]... foo = "bar"  # String... """>>>doc=parse(content)# doc is a TOMLDocument instance that holds all the information# about the TOML string.# It behaves like a standard dictionary.>>>assertdoc["table"]["foo"]=="bar"# The string generated from the document is exactly the same# as the original string>>>assertdumps(doc)==contentModifyingATOML provides an intuitive API to modify TOML documents.>>>fromatomlimportdumps>>>fromatomlimportparse>>>fromatomlimporttable>>>doc=parse("""[table]... foo = "bar"  # String... """)>>>doc["table"]["baz"]=13>>>dumps(doc)"""[table]foo = "bar"  # Stringbaz = 13"""# Add a new table>>>tab=table()>>>tab.add("array",[1,2,3])>>>doc["table2"]=tab>>>dumps(doc)"""[table]foo = "bar"  # Stringbaz = 13[table2]array = [1, 2, 3]"""# Remove the newly added table>>>doc.remove("table2")# del doc["table2] is also possibleWritingYou can also write a new TOML document from scratch.Let's say we want to create this following document:# This is a TOML document.title="TOML Example"[owner]name="Tom Preston-Werner"organization="GitHub"bio="GitHub Cofounder & CEO\nLikes tater tots and beer."dob=1979-05-27T07:32:00Z# First class dates? Why not?[database]server="192.168.1.1"ports=[8001,8001,8002]connection_max=5000enabled=trueIt can be created with the following code:>>>fromatomlimportcomment>>>fromatomlimportdocument>>>fromatomlimportnl>>>fromatomlimporttable>>>doc=document()>>>doc.add(comment("This is a TOML document."))>>>doc.add(nl())>>>doc.add("title","TOML Example")# Using doc["title"] = "TOML Example" is also possible>>>owner=table()>>>owner.add("name","Tom Preston-Werner")>>>owner.add("organization","GitHub")>>>owner.add("bio","GitHub Cofounder & CEO\nLikes tater tots and beer.")>>>owner.add("dob",datetime(1979,5,27,7,32,tzinfo=utc))>>>owner["dob"].comment("First class dates? Why not?")# Adding the table to the document>>>doc.add("owner",owner)>>>database=table()>>>database["server"]="192.168.1.1">>>database["ports"]=[8001,8001,8002]>>>database["connection_max"]=5000>>>database["enabled"]=True>>>doc["database"]=databaseInstallationIf you are usingPDM,
