# callback-set with reentrant invocation
|
|
|
|
Reentrant:
|
|
1. A callback can modify parent callback-set (for example to remove itself),
|
|
even while being invoked.
|
|
2. Any such re-entrant operations are deferred until callback invocation completes.
|
|
|
|
## Getting Started
|
|
|
|
### build + install dependencies
|
|
|
|
- [github/Rconybea/refcnt](https://github.com/Rconybea/refcnt)
|
|
|
|
### build + install
|
|
|
|
```
|
|
$ cd xo-callback
|
|
$ mkdir build
|
|
$ cd build
|
|
$ INSTALL_PREFIX=/usr/local # or wherever you prefer, e.g. ~/local
|
|
$ cmake \
|
|
-DCMAKE_MODULE_PATH=${INSTALL_PREFIX}/share/cmake \
|
|
-DCMAKE_PREFIX_PATH=${INSTALL_PREFIX} \
|
|
-DCMAKE_INSTALL_PREFIX=${INSTALL_PREFIX} ..
|
|
$ make
|
|
$ make install
|
|
```
|
|
(also see .github/workflows/main.yml)
|
|
|
|
### build for unit test coverage
|
|
|
|
```
|
|
$ cd xo-callback
|
|
$ mkdir build-ccov
|
|
$ cd build-ccov
|
|
$ cmake \
|
|
-DCMAKE_MODULE_PATH=${INSTALL_PREFIX}/share/cmake \
|
|
-DCMAKE_PREFIX_PATH=${INSTALL_PREFIX} \
|
|
-DCODE_COVERAGE=ON \
|
|
-DCMAKE_BUILD_TYPE=Debug ..
|
|
```
|
|
|
|
### LSP (language server) support
|
|
|
|
LSP looks for compile commands in the root of the source tree;
|
|
cmake creates them in the root of its build directory.
|
|
```
|
|
$ cd xo-callback
|
|
$ ln -s build/compile_commands.json
|
|
```
