Writing an environment: Place it in environments//_load.sh When unloaded, it will execute environments//_teardown.sh Add hooks to environments//.sh
Extensions are small plugins for buildenv that provide extra functionality, such as prompt information, support for other buildsystems, environment variables, etc.
To enable an extension, edit $BUILDENV_HOME/config/$USER.sh and add the following:
Hooks that begin with an underscore handle special events that affect a single buildenv or extension.
_load Called once, when the environment or extension is loaded. A great place to define any library functions needed.
_teardown Called once, when the environment or extension is unloaded. A great place to run any cleanup code, such as undefining functions.
These hooks represent various events in the buildenv system.
buildenv-loaded A new buildenv is loaded
buildenv-unloaded A buildenv is unloaded
buildenv-changed The current 'master' buildenv is changed
init Buildenv is completely loaded
report Called from within buildenv_report.
restore-all _buildenv_restore_all is about to restore the environment to original values
load-config A configuration is activated.
firstrun 'buildenv' was executed for the first time. Useful for any kind of initialization you'd otherwise want to delay until you know the user will be actually using buildenv.
prompt Whenever the shell prompt is regenerated. WARNING: This function needs to be pretty much instant, as bash does not show the prompt 'till it is done.
There is a rudimentary update mechanism that assumes $BUILDENV_HOME is a git repository, originally cloned from somewhere (has an 'origin' remote).
To use, run buildenv_update
