Bugs are tracked as GitHub issues. After you've determined which repository your bug is related to, create an issue on that repository and provide the details.
We aim at syntax compatibility with 3 languages at once: MQL4, MQL5 and C++.
To optimize the code for readability, please follow these guidelines:
- Indent using two spaces (soft tabs).
- Consider the people who will read your code, and make it look nice for them.
We use a clang-format code formatter tool to format the code
(both MQL and C++ files).
For example, to format file inplace, run:
clang-format -i File.mqh
To improve code compatibility, please use the following syntax:
| MQL | C++ | Syntax to use |
|---|---|---|
&this |
this |
THIS_PTR |
GetPointer(obj) |
*obj |
GET_PTR(obj) |
T name[] |
_cpp_array<T> name |
ARRAY(T, name) |
T<A, B> N[] |
_cpp_array<T<A, B>> N |
ARRAY(T<A, B>, N) |
obj.Method() |
obj->Method() |
obj PTR_DEREF Method() |
obj.a1.a2 |
obj->a1->a2 |
PTR_ATTRIB2(obj, a1, a2) |
obj.attr |
obj->attr |
PTR_ATTRIB(obj, attr) |
str == NULL |
str == NULL |
IsNull(str) |
