◆ addIdentifierChar()

void addIdentifierChar ( char c )

adds a valie character to an identifier

Here is the caller graph for this function:

◆ doneParsingIdentifier()

void doneParsingIdentifier ( )

finished parsing an identifier

Definition at line 163 of file TokenParser.cpp.

Here is the call graph for this function:

Here is the caller graph for this function:

◆ getIdentifier()

char * getIdentifier ( int num )

the nth identifier

Definition at line 137 of file TokenParser.cpp.

◆ getIdentifierStruct()

IdentifierStruct getIdentifierStruct ( int num )

grab full identifier struct (Pointer?)

Definition at line 143 of file TokenParser.cpp.

Here is the caller graph for this function:

◆ getToken()

TokensEnum getToken ( int num )

get the nth token

Definition at line 132 of file TokenParser.cpp.

Here is the caller graph for this function:

◆ initIdentifier()

void initIdentifier ( char c )

initi for each new identifier

Definition at line 156 of file TokenParser.cpp.

Here is the call graph for this function:

Here is the caller graph for this function:

◆ initParser()

void initParser ( )

initialize the parser

Definition at line 242 of file TokenParser.cpp.

Here is the caller graph for this function:

◆ nameMatchesWildcardQuery()

boolean nameMatchesWildcardQuery	(	char *	name,
		IdentifierStruct	idQueryStruct
	)

These are CASE SENSITIVE matches ... matches name with wildcards and the idToMatch name is what is being queried, the idQueryStruct is the QUERY

See also: https://legacy.cplusplus.com/reference/cstring/strncmp/ eg. idToMatch == M5 and wildcard after and before, then just search for idToMatch in name If not before, then starts with ... if non, then strmatch

see if there was a NOT (!)

Definition at line 363 of file TokenParser.cpp.

Here is the caller graph for this function:

◆ numIdentifiers()

int numIdentifiers ( )

how many identifiers

Definition at line 127 of file TokenParser.cpp.

◆ numTokens()

int numTokens ( )

how many tokens

Definition at line 122 of file TokenParser.cpp.

Here is the caller graph for this function:

◆ parseQueryLine_mainModule()

void parseQueryLine_mainModule ( char * line )

parses a line of text, returning the number of tokens..

parses a line of text, The caller then uses queryMatchesName() to see if their name matches

NOTE: doesn't support the BLE addresses like: DevQuery: !M5Laybrinth & !84:cc:a8:7a:f6:aa

initialize the variables for parsing this line

if no query params, then make it an identifier and exit

if parsing still then add to identifier

start a new identifier..

init the identifier

else not valid identifier (so a follow..)

done parsing if not a valid identifier character

finishIdNeeded is before pushing another token, unless a not or wildcard

now classify this char if an identifier modifier

! and * belong to the identifier object if a modifier of ident (~ or *) then push the token, and process the identifier

an operator or space if inside an identifier, finish it first

process the token

& and | are expression modifiers

if end of line, and was parsing an identifier .. then finish

Definition at line 258 of file TokenParser.cpp.

Here is the call graph for this function:

◆ parseSM_For_UUID_Flownum()

char * parseSM_For_UUID_Flownum ( char * semanticMarker )

3.29.25 Raiiiinier Beeer movie last night add returning a UUID.FLOWNUM if valid, or nil if nota note "flow" .. not flownum uuid=x&flow=y& .. flownum could be the last .. so end-of-line

syntax: uuid=X&flownum=Y

needed to copy semanticMarker .. as the code below broke the callers' value to "https:" .. SIDE EFFECT

look for tokens

break by '&'

advance quealIndex past the equal

Definition at line 838 of file TokenParser.cpp.

Here is the caller graph for this function:

◆ popTokenStack()

TokensEnum popTokenStack ( )

get the current top of stack token, and move the token stack pointer

else pop

Definition at line 95 of file TokenParser.cpp.

Here is the caller graph for this function:

◆ processIdentifier()

void processIdentifier ( )

push identifier .. looks at the stack and fills in the identifier object called after seeing a & or | (the follow set of the identifier, after a *)*

the index is already 1 past..

look at stack

replace the stack with our filled out identifier

Definition at line 191 of file TokenParser.cpp.

Here is the call graph for this function:

Here is the caller graph for this function:

◆ pushIdentifier()

void pushIdentifier ( char * identifier )

pushes identifier onto identifier stack, while also inserting a token for identifier

now save Identifier

Definition at line 112 of file TokenParser.cpp.

Here is the call graph for this function:

Here is the caller graph for this function:

◆ pushToken()

void pushToken ( TokensEnum token )

pushes token onto token stack

Definition at line 72 of file TokenParser.cpp.

Here is the caller graph for this function:

◆ queryMatchesName_mainModule()

boolean queryMatchesName_mainModule ( char * name )

now need to process the token tree to see if name1 and name2 match the query eg. ! name & name2 ... wildcards after name make it slightly complicated SO: look for wildcards before and after, and the id. then decide if that matches before the boolean and notmodifier applied

basically for each identifier in the query, the names (1&2) have to be compared each time..

what the last boolean_enum was..

the result of A <> B

Here is the call graph for this function:

Here is the caller graph for this function:

◆ semanticMarkerToJSON_TokenParser()

char * semanticMarkerToJSON_TokenParser ( char * semanticMarker )

3.23.25 rainy weekend create a JSON string from the SemanticMarker https://semanticmarker.org/bot/setdevice/scott@konacurrents.com/PASS/M5AtomSocket/socket/on} Create a JSON knowing the "bot" syntax, eg. setdevice/USER/PASS/device/<set>/<flag> and others like set etc. Maybe not 'dev' here. Others cmddevice/USER/PASS return: {'set':<set>,"dev': set- sends the message (command/value) to all device Supports these for now: GET /set/{username}/{password}/{command}/{value} GET /send/{username}/{password}/{request} only support 'device' ones GET /setdevice/{username}/{password}/{devicename}/{command}/{value} GET /senddevice/{username}/{password}/{device}/{request} return "" if not valid

not supported

if set then there will be more .. so add ',' if send then this is the end (no ',')

replace ' with "

Here is the caller graph for this function:

◆ setup_tokenParser_mainModule()

void setup_tokenParser_mainModule ( )

setup a test ..

setup for the token parser (really just for testing)

Here is the caller graph for this function:

◆ stringIsQuery_mainModule()

boolean stringIsQuery_mainModule ( char * line )

whether the stirng is a potential query

whether the stirng is a potential query. This can be used, but it is also used by the parseQueryLine to optimize out the original dev:name query.

Definition at line 412 of file TokenParser.cpp.

Here is the caller graph for this function:

◆ topOfTokenStack()

TokensEnum topOfTokenStack ( )

get the current top of stack token

otherwise grab the top

Definition at line 85 of file TokenParser.cpp.

Here is the caller graph for this function:

◆ validIdentifierChar()

boolean validIdentifierChar ( char c )

whether the character is a valid identifier character 1.22.24 adding ":" so fits a BLE address DevQuery: !M5Laybrinth & !84:cc:a8:7a:f6:aa
