 | |
| breakpoint commands are two-word commands, the user would still need to \
 | |
| enter the second word after 'bp', e.g. 'bp enable' or 'bp delete'."
 | |
|         R"(
 | |
| 
 | |
| (lldb) command alias bpl breakpoint list
 | |
| 
 | |
|     Creates the abbreviation 'bpl' for the two-word command 'breakpoint list'.
 | |
| 
 | |
| )"
 | |
|         "An alias can include some options for the command, with the values either \
 | |
| filled in at the time the alias is created, or specified as positional \
 | |
| arguments, to be filled in when the alias is invoked.  The following example \
 | |
| shows how to create aliases with options:"
 | |
|         R"(
 | |

 | |
| (lldb) command alias bfl breakpoint set -f %1 -l %2

 | |
| options already part of the alias.  So if the user wants to set a breakpoint \
 | |
| by file and line without explicitly having to use the -f and -l options, the \
 | |
| user can now use 'bfl' instead.  The '%1' and '%2' are positional placeholders \
 | |
| for the actual arguments that will be passed when the alias command is used.  \
 | |
| The number in the placeholder refers to the position/order the actual value \
 | |
| occupies when the alias is used.  All the occurrences of '%1' in the alias \
 | |
| will be replaced with the first argument, all the occurrences of '%2' in the \
 | |
| alias will be replaced with the second argument, and so on.  This also allows \
 | |
| actual arguments to be used multiple times within an alias (see 'process \
 | |
| launch' example below)."
 | |
|         R"(

 | |

 | |
|         "Note: the positional arguments must substitute as whole words in the resultant \
 | |
| command, so you can't at present do something like this to append the file extension \
 | |
| \".cpp\":"
 | |
|         R"(
 | |
| 
 | |
| (lldb) command alias bcppfl breakpoint set -f %1.cpp -l %2
 | |
| 
 | |
| )"
 | |
|         "For more complex aliasing, use the \"command regex\" command instead.  In the \
 | |
| 'bfl' case above, the actual file value will be filled in with the first argument \
 | |
| following 'bfl' and the actual line number value will be filled in with the second \
 | |
| argument.  The user would use this alias as follows:"
 | |
|         R"(

 | |
| (lldb) command alias bfl breakpoint set -f %1 -l %2
 | |
| (lldb) bfl my-file.c 137
 | |

 | |
| This would be the same as if the user had entered 'breakpoint set -f my-file.c -l 137'.

| rather than using a positional placeholder:"

|         R"(
