but that was before the branch, and i'd like to get at least an initial version of this functionality into 6.8. so i've implemented (draft patches wrt current head attached):- :browse! a variant of :browse, that does not filter out children, and does not display children in context of their parents
(as described; this still suffers from the issue that i have not
found a function to display the stored type of class methods
correctly; it also does not yet account for qualified names,
when their unqualified versions are available, nor does it
address the issue of not updating properly on :reload, both
issues are described in ticket #1617)
[btw, how did the debugger manage to steal :b from
:browse? i think this should be changed back to the
traditional (pre 6.7) behaviour, but have not done so yet]
- GHCi command output capture (again, as described)
for :help, :browse, :info, :set, :show (showModules,
showBindings,showBkptTable,showContext).
mostly this has been about refactoring hardcoded i/o
into separate i/o and rendering, so that the rendered
output can be captured in a variable ('output'). the
capturing itself is isolated in a single function ('out'),
so changing the variable name would be easy.
there are probably other commands one would want
to capture later. there is a new renderForUser (for use
with out, making it easier to replace the all too popular
printForUser).
the patches seem to affect the output of tests (fast stage=2) only in two cases, break006 and print003, both of which use :show bindings (which is obviously aware of the new 'output' variable), so i suggest to accept the new output for these two tests. i would still like to know how one is supposed to displaythe type of class methods, and why 'it' is not bound in the same naive way i've used to bind 'output'. once these two
issues are addressed, i still need to add a couple of tests, as well as some documentation.. could you please have a look into this? claus
