Provides debugger with command and command arguments completion compliments of bond.
Install the gem with:
gem install debugger-completion
To have debugger automatically use this gem:
echo "eval require 'debugger/completion'" >> ~/.rdebugrc
Or to require in a script or application, place after your require 'debugger' line:
require 'debugger/completion'
Or if you like to debug with one-liners:
require 'debugger/completion'; debugger
Or if using rdebug:
rdebug -r debugger/completion FILE
To start manually in environments with bond completion already setup i.e. irb:
require 'debugger/completion'
Debugger::Completion.start
Let's autocomplete instance and local variables of the current binding as well as debugger commands:
186 end
187
188 def render
189 body = []
190 require 'debugger'; debugger
=> 191 unless @rows.length ## 0
192 setup_field_lengths
193 body += render_header
194 body += render_rows
195 body += render_footer
(rdb:1) [TAB]
@fields condition finish ps thread
@filter_classes continue frame putl tmate
@headers delete help quit trace
@options disable info reload undisplay
@rows display irb restart up
backtrace down list save var
body edit method set where
break enable next show
catch eval p source
completion_toggle exit pp step
(rdb:1) ca[TAB]
(rdb:1) catch
(rdb:1) @fie[TAB]
(rdb:1) @fields
(rdb:1) bo[TAB]
(rdb:1) body
Autocomplete methods of local and instance variables:
(rdb:1) @filter_classes.[TAB]
Display all 150 possibilities? (y or n)
(rdb:1) body.[TAB]
Display all 168 possibilities? (y or n)
Autocomplete debugger command arguments:
# What info does debugger provide?
(rdb:1) info [TAB]
args display global_variables locals thread
breakpoints file instance_variables program threads
catch files line stack variables
(rdb: 1) info d[TAB]
(rdb: 1) info display
# What settings can I change?
(rdb:1) set [TAB]
annotate autolist forcestep linetrace width
args basename fullpath linetrace+
autoeval callstyle history listsize
autoirb debuggertesting keep-frame-bindings trace
(rdb:1) set d[TAB]
(rdb:1) set debuggertesting
Since I have autoeval on, why not autocomplete as if I'm in irb?
# Execute command provided by this gem
(rdb:1) completion_toggle # also aliased to ct
# irb-like completion has been enabled
(rdb:1) [TAB]
Display all 347 possibilities? (y or n)
(rdb:1) De[TAB]
(rdb:1) Debugger
(rdb:1) Debugger.[TAB]
Display all 137 possibilities? (y or n)
(rdb:1) require 'ab[TAB]
(rdb:1) require 'abbrev.rb'
Huh? Argument autocompletion? See bond for all that you can autocomplete.
Can I go back to basic debugger completion?
# Invoke completion_toggle again
(rdb:1) completion_toggle
(rdb:1) [TAB]
@fields condition finish ps thread
@filter_classes continue frame putl tmate
@headers delete help quit trace
@options disable info reload undisplay
@rows display irb restart up
backtrace down list save var
body edit method set where
break enable next show
catch eval p source
completion_toggle exit pp step
Please, can I just quit quickly without a prompt?
(rdb:1) q [TAB]
(rdb:1) q unconditionally
