px_golang2cpp
convert go to cpp
- convert map to std::unordered_map
- convert array to vector
- convert 'var test bool' to 'bool test{}'
- convert 'var test = 2' to 'auto test = 2;'
- convert 'var test []string' to 'vector test{};'
- convert 'var test map[int]string' to std::unordered_map<int,string> test{};
usage
clone source code
- git clone [email protected]:awfeequdng/px_golang2cpp.git
build the project
-
- cd px_golang2cpp source directory
-
- exec the cmd:
go build *.go,then execuable filemainis created
- exec the cmd:
generate a cpp file from go source code
-
- we have test file in directory
test, we now chose thetest/func.go
- we have test file in directory
-
- execute the command:
./main test/func.go -o test.cc, then we get a cpp file:test.cc
- execute the command:
build the created cpp source file
- we now have the test.cc file, then we can execute the command like this:
g++ test.cc - if there have no error in building the cpp file
test.cc, then we get the correct cpp source form go
notice
- the created cpp source file is just for testing, and some converted code build failed dure to lack of dependence file.
example
- convert var in go to cpp:
./main test/var_test.go -o var_test.cc
// var_test.go
package var_test
var endings = []string{"{", ",", "}", ":"}
var test = -1
var test1 = 2
var g1, g2 = 23, "fjdd"
var (
switchExpressionCounter = -1
firstCase bool
switchLabel string
labelCounter int
iotaNumber int // used for simple increases of iota constants
deferCounter int
unfinishedDeferFunction bool
)
var globalObjectMap map[string]string
// var_test.cc (this is part of code)
std::vector<string> endings{
"{",
",",
"}",
":",
};
auto test = (-1);
auto test1 = 2;
auto g1 = 23;
auto g2 = "fjdd";
auto switchExpressionCounter = (-1);
bool firstCase{};
string switchLabel{};
int labelCounter{};
int iotaNumber{};
int deferCounter{};
bool unfinishedDeferFunction{};
notice: cpp code not format yet(we will do it later).
- convert go map to cpp unordered_map:
./main test/map_test.go -o map_test.cc
// map_test.go
package map_test
var includeFileMap map[string]string = make(map[string]string)
var includeMap = map[string]string{
