    • file
    • array(reshape, spread, transpose)
  • io formatter
  • optional parameters
  • keyword parameter list
  • reference in parameter list
  • rewrite paramtable and var_def(simplify right-recursive rules, move dimension to dummy_variale_iden)
  • more elegant multi-word keyword handler(instead of defined in regular expression)
  • function forward declaration(if necessary)
  • c-style array(partial)
  • variable with type

  • comments
  • one-line if
  • error infomation include Intent name
  • allow named blocks
  • support function pointers, Parse Interface for function pointer
  • hidden do
  • more precise code/error location, start/end
  • optimize ParseNode with rvalue
  • support fortran77 standard
  • farray
  • goto stmt
  • use fortran array [from, to] rather than [from, to)
  • promote return type in formerge so it can accept 2 different type farray
  • fslice return by reference
  • C.13.2.1 Unconditional array computations and C.13.2.2 Conditional array computations
  • underscore kind param, like .93E7_QUAD ref standard 4.3.1.2
  • keyword conflict between fortran and c++, such as class, struct, int
  • arithmatic if
  • labeled do, if
  • exit, cycle outer do-loop
  • detailed type attr(add TokenMeta::Int64, etc.), use TokenMeta::Implicit_Decl, clean TokenMeta enum
  • unicode file
  • underscore kind-param for all type literal(ref 4.3.2.1)
  • display comments
  • support other C++ compilers
  • free format continuation(ref 3.3.1.3)
  • optimize performance
    • gen_merge
    • RETURN_NT eliminate copy from T to T *
  • range
    • ref ConfigImplicit

todolist(bugfix)

  • if slice can be a scalar x and equal to (1: x + 1), there will be conflict in argtable
  • more specific type cast functions(char, int, long long)
  • read statement undefined device
  • minus 1 and negative 1 conflict(modify definition in .l)
  • either an interface or forward declaraion of return value is need when calling functions in fortran, so must remove all interface and forward declaraion of function return value in generated code in order to avoid repeat definition.
  • error message line info is always 0
  • handle error when can't find declaration of the variable listed in function paramtable
  • handle with empty line
  • split keyvalue rules from paramtable rules, may cause bugs
  • _type_kind rules and type cast function call conflict
  • solve paramtable : exp, argtable : exp conflict by merging argtable to paramtable 1. merge argtable and dimen_slice to paramtable 2. only change reduce rules
  • printf array
  • fixed length character initialize with shorter characters
  • add arraybuilder rule to exp rules
  • use make_str_list function replace some ugly code
  • hidden do(io-implied-do, ac-implied-do, data-implied-do)
  • pointer problem, including VariableDesc::slice, deal with nullptr
  • ParseNode inteface change to reference, remove pointer in other structures
  • won't generate repeated definitions in implicit paramtable 
    subroutine sub(A)
    A = 2
end subroutine
  • temporary_variable to FunctionInfo variable
  • regen_if, regen_do, regen_suite
  • delete all gen_ functions except gen_token with multiple which accepts a list of YYSTYPE. regen_paramtable, regen_function_array
  • log all arguments in paramtable to get_context().variable
  • use is_exp function instead of NT_EXPRESSION node. rename NT_EXPRESSION to NT_ARITH_EXP, which constructed only by arithmatic rules
  • declare all implicit variables (ref demos/implicit variable.txt)
  • implicit variable in variable declaration like: 
    integer a = c
  • solve (i+1,i+2, i = 1, 2) in IO function
  • tokenizer: real type(4.3.1.2) conflict with operators, refer demos/control/tokenizer.txt
  • enum-reflect.h can not calculate value like Void - 100, refer make_enum_table's TODO
  • change VariableInfo::vardef_node from pointer to ParseNode
  • interface function's local_name, ref get_full_paramtable
  • regen_exp and regen_slice should be called exactly once in get_sliceinfo_base method
