source: owl.c @ 7eaa83b

release-1.9
Last change on this file since 7eaa83b was 389d487, checked in by David Benjamin <davidben@mit.edu>, 10 years ago
Switch to interactive context before sourcing the startup file There are no invariants that don't hold before the previous place we flip the interactive bit; although default_style is applied afterwards, there is still a style set before that code. There is no code which reads the READCONFIG bit, so no behavior should change from there. Setting the interactive bit makes owl_function_load{login,}subs noisier, but that's fine. A number of commands were labeled OWL_CTX_INTERACTIVE, but that doesn't change much because, unless the command is OWLCMD_*_CTX, the bits are ignored. What does change is that .owl/startup is allowed to leave with a context on the stack. In particular, this /finally/ fixes #161. More fundamentally, this makes .owl/startup identical to the user having run those commands in succession, which is a nice simplification.
