CodeAnalysis: Tools for Static Analysis of R code

The following are functions that have calls to rstatic functions that are not also in base or in CodeAnalysis.

The rstatic functions called are + as_language + children + children<- + find_nodes + is_symbol + match_call + replace_nodes + rstatic::arg_index + rstatic::arg_value + rstatic::as_language + rstatic::find_nodes + rstatic::Symbol + rstatic::to_ast + to_ast + where_is

Also look for $fn, $value, ....

"Symbol" "ListOfCalls"

Exported functions that use rstatic functions but not called (5)

[test] findCallsParam
callsFunParam.R
changed
√ [removed] rlangType
not used. Could be removed.
removed
[test] findNSE
NSE.R
not called by anything
changed
[test] getFilesRead
readFile.R
not called within package
[test] findUsedOptions
options.R
not called within package
see tests/options.R for test cases

Exported functions that use rstatic functions (2)

[test] isCallTo
callsTo.R
remove rstatic part.
[test] getURLs
freeVariables.R
changed to use findLiterals() and then filter.
[test] isFunAssign
- freeVariables.R
- removed the rstatic if part
[test] isIfFalse
- freeVariables.R
- removed the rstatic if part

Not exported but called (13)

But could be called by a function that is not itself called or exported.

[removed] asFunction
used in countNestedFunctionLevel
not any longer.
[remove] asScript
used in findLiteralValue
[remove] asToplevelExpr
used in findLiteralValue
[test] countNestedFunctionLevel
Moved these three to findLiteralValue.
These walk back up the AST. So need to reimplement.
[removed] collectRemoveFun
[removed] removeFromBody
- both related to extractFunctions.
[removed] renameVarFun
- used in changeParamName
[reimplemented] changeParamName
- used in addParams()
checkVariableDependency
- used in checkLoopDepend
checkUnique
- checkLoopDepend.R
- but only called from checkLoopDepend() which is not exported.
[test] passGlobals
passGlobals.R
rewrites language objects to rename variable
used in mkGlobalsLocal()
[removed] updateCallsFun
- used in passGlobals
- addParams and
[test] getUsedOptionName
[false positive] findMissingVariables
- accesses defs$variable but that is okay.
[test] varAppears
use getAllSymbols()
[test] findAssignsOverVar
use findAssignsTo
[test] findAllUpdates
use findAssignsTo
[removed] paramValue
calls findLiteralValue()
checks if is(, "Literal")
called from getCallParam() (freeVariables.R) and getS3ClassInfo() (2 times in packageAnalysis.R)
- getS3ClassInfo not used apparently. See S3Assigns.R Probably more robust.
[removed] usedAsFunction
- freeVariables.R
- removed
- use findCallsParam() instead.
[test] getCallParam
- freeVariables.R
- removed rstatic code from function
[test] getAssignedVars
ifAssignment.R
uses findAssignsTo()
¿¿¿ Do we want to complex = TRUE/FALSE?
[test & fix] usesDotsI
- usesDots.R
- determine whether to include list(...) as a separate element or only in assignments or calls. e.g., a = list(...) or foo(list(...))
