- Improved documentation for using declarations.
- Issue new warning WARN_LANG_USING_NAME_DIFFERENT when there
is a conflict in the target language name to be used when
introducing a method via a using declaration. Previously
the method was silently ignored. Issue #1840. Issue #655.
An invalid preprocessor expression is reported as a pair of
warnings with the second giving a more detailed message from the
expression evaluator. Previously SWIG prefixed the second message
with "Error:" - that was confusing as it's actually only a warning
by default so we've now dropped this prefix.
Before:
x.i:1: Warning 202: Could not evaluate expression '1.2'
x.i:1: Warning 202: Error: 'Floating point constant in preprocessor expression'
Now:
x.i:1: Warning 202: Could not evaluate expression '1.2'
x.i:1: Warning 202: Floating point constant in preprocessor expression
See #1465
A subexpression in parentheses lost its string/int type flag and
instead used whatever type was left in the stack entry from
previous use. In practice we mostly got away with this because
most preprocessor expressions are integer, but it could have
resulted in a preprocessor expression incorrectly evaluating as
zero. If -Wextra was in use you got a warning:
Warning 202: Error: 'Can't mix strings and integers in expression'
Fixes#1384
This commit handles multi-version support at runtime, it
fixes:
* 5.5.2 - with cutted long identifier name
* 6.0.0 - with full string identifier
* 6.1.0 - with 1 or 0 output argument
It also improves the codebase by:
* Using `Char(X)` instead of `DohCheck(X)` and `Data(X)`
* Using `Len(X)` instead of `strlen()`
* Correctly detecting old Scilab versions
This commit log Scilab version at ./configure to ease maintenance. It
uses Scilab include next to the bin directory which will work for both
system-wide install and binaries from scilab.org.
SCILAB_VERSION is define as an automake variable for easier
failure investigation.
Note: the Ubuntu Scilab version is used when available, in the current
CI config there is:
* Scilab 5.5 from scilab.org
* Scilab 6.0 from Ubuntu 18.04
* Scilab 6.1 from Ubuntu 20.04
Implementation is very similar to typedef implementation.
Issue #655 and closes#1488.
Testcase using_member.i.
Better implementation to that reverted in previous commit 3f36157b.
Symbol tables shown with -debug-csymbols and -debug-symbols now correct
and are similar to when using a typedef.
If it's not a recognised directive the scanner now emits MODULO and then
rescans what follows, and if the parser then gives a syntax error we
report it as an unknown directive. This means that `a%b` is now allowed
in an expression, and that things like `%std::vector<std::string>` now
give an error rather than being quietly ignored.
Fixes#300Fixes#368
Test both abstract and concrete base classes, with simple int/bool data.
This level of complexity is very helpful when setting up director
functionality for a new target language.
Even in the case of just creating a `DerivedClass` this test says:
```
swig/python detected a memory leak of type 'DerivedClass *', no destructor found.
```
even though the destructor is defined in the base class.
Tests that the `%contract` code (viz., each target language's
implementation of SWIG_contract_assert) compiles in C as expected. Update
the note in the source code since `%contract` is in the official
documentation.
Otherwise, generating the `clientdata_prop` modules will duplicate symbols,
leading to linker errors if the resulting modules are linked (or possibly
loaded) simultaneously.
