Here's what the output looks like: https://reviews.llvm.org/P8170 $ ninja docs-lldb-man [1/1] Generating man Sphinx documentation for lldb into "/Volumes/Jonas/llvm/build-ra/tools/lldb/docs/man" $ nroff -man /Volumes/Jonas/llvm/build-ra/tools/lldb/docs/man/LLDB.1 | col -bx This patch replaces the existing out-of-date man page for lldb and replaces it with an RST file from which sphinx generates the actual troff file. This is similar to how man pages are generated for the rest of the LLVM utilities. The man page is generated by building the `docs-lldb-man` target.

+==================== + +.. program:: lldb + +SYNOPSIS +-------- + +| :program:`lldb` [*options*] *executable* + +DESCRIPTION +----------- + +:program:`lldb` is the command line interface for the LLDB

unless --no-lldbinit is passed. + +.. option:: --no-lldbinit + + Do not automatically parse any '.lldbinit' files. + +.. option:: --one-line-before-file <command> + + Tells the debugger to execute this one-line lldb command before any file provided on the command line has been loaded. + +.. option:: --one-line-on-crash <command> + + When in batch mode, tells the debugger to source this file of lldb commands if the target crashes. + +.. option:: --one-line <command> + + Tells the debugger to execute this one-line lldb command after any file provided on the command line has been loaded. + +..

option:: -s <value> + + Alias for --source + +.. option:: -x + + Alias for --no-lldbinit + +OPTIONS +------- + +.. option:: --arch <architecture> + Tells the debugger to use the specified architecture when starting and running the program. +.. option:: -a <value> + Alias for --arch +.. option:: --capture-path <filename> + + Tells the debugger to use the given filename for the reproducer. + +.. option:: --capture + + Tells the debugger to capture a reproducer. + +.. option:: --core <filename> + + Tells the debugger to use the full path to <filename> as the core file. + +.. option:: -c <value> + + Alias for --core + +.. option:: --debug + + Tells the debugger to print out extra information for debugging itself. + +.. option:: -d + + Alias for --debug + +.. option:: --editor + +

--repl=<flags> + +.. option:: --repl-language <language> + + Chooses the language for the REPL. + +.. option:: --repl=<flags> + + Runs lldb in REPL mode with a stub process with the given flags. + +..

file for this version of lldb. + +.. option:: -P + + Alias for --python-path + +.. option:: --script-language <language> + + Tells the debugger to use the specified scripting language for user-defined scripts. + +EXAMPLES +-------- + +The debugger can be started in several modes. + +Passing an executable as a positional argument prepares lldb to debug the +given executable. Arguments passed after -- are considered arguments to the +debugged executable. + + lldb --arch x86_64 /path/to/program -- --arch arvm7 + +Passing one of the attach options causes lldb to immediately attach to the +given process. + + lldb -p <pid> + lldb -n <process-name> + +Passing --repl starts lldb in REPL mode. + + lldb -r + +Passing --core causes lldb to debug the core file. + + lldb -c /path/to/core + +Command options can be combined with these modes and cause lldb to run the +specified commands before or after events, like loading the file or crashing, +in the order provided on the command line. + + lldb -O 'settings set stop-disassembly-count 20' -o 'run' -o 'bt' + lldb -S /source/before/file -s /source/after/file + lldb -K /source/before/crash -k /source/after/crash + +Note: In REPL mode no file is loaded, so commands specified to run after +loading the file (via -o or -s) will be ignored. + +USING LLDB +---------- + +In lldb there is a help command which can be used to find descriptions +and examples of all lldb commands. To get help on "breakpoint set" you +would type "help breakpoint set". + +There is also an apropos command which will search the help text of all +commands for a given term ‐‐ this is useful for locating a command by topic. +For instance, "apropos breakpoint" will list any command that has the word +"breakpoint" in its help text. + +FILES +----- + +lldb will read settings/aliases/commands from three files at startup, if they +exist. + +First, it will read a ~/.lldbinit‐debugger command file. If you are using the +lldb command line interface, this is ~/.lldbinit‐lldb. If you are using lldb +inside a GUI debugger like Xcode this will be ~/.lldbinit‐Xcode. This is a +useful place to put settings that you want to apply only when a given lldb +command interpreter is used. + +Second, ~/.lldbinit is read. + +Third, an .lldbinit file in the current working directory (where lldb is +started) will be read. + +SEE ALSO +-------- + +The LLDB project page https://lldb.llvm.org has many different resources +for lldb users ‐‐ the gdb/lldb command equivalence page +https://lldb.llvm.org/use/map.html can be especially helpful for users +coming from gdb.
