| 2003 | SetHelpLong( |

| 2005 | Breakpoint names provide a general tagging mechanism for breakpoints. Each |
| 2006 | breakpoint name can be added to any number of breakpoints, and each breakpoint |
| 2007 | can have any number of breakpoint names attached to it. For instance: |
| 2008 | |
| 2009 | (lldb) break name add -N MyName 1-10 |
| 2010 | |
| 2011 | adds the name MyName to breakpoints 1-10, and: |
| 2012 | |
| 2013 | (lldb) break set -n myFunc -N Name1 -N Name2 |
| 2014 | |
| 2015 | adds two names to the breakpoint set at myFunc. |
| 2016 | |
| 2017 | They have a number of interrelated uses: |
| 2018 | |
| 2019 | 1) They provide a stable way to refer to a breakpoint (e.g. in another |
| 2020 | breakpoint's action). Using the breakpoint ID for this purpose is fragile, since |
| 2021 | it depends on the order of breakpoint creation. Giving a name to the breakpoint |
| 2022 | you want to act on, and then referring to it by name, is more robust: |
| 2023 | |
| 2024 | (lldb) break set -n myFunc -N BKPT1 |
| 2025 | (lldb) break set -n myOtherFunc -C "break disable BKPT1" |
| 2026 | |
| 2027 | 2) This is actually just a specific use of a more general feature of breakpoint |
| 2028 | names. The <breakpt-id-list> argument type used to specify one or more |
| 2029 | breakpoints in most of the commands that deal with breakpoints also accepts |
| 2030 | breakpoint names. That allows you to refer to one breakpoint in a stable |
| 2031 | manner, but also makes them a convenient grouping mechanism, allowing you to |
| 2032 | easily act on a group of breakpoints by using their name, for instance disabling |
| 2033 | them all in one action: |
| 2034 | |
| 2035 | (lldb) break set -n myFunc -N Group1 |
| 2036 | (lldb) break set -n myOtherFunc -N Group1 |
| 2037 | (lldb) break disable Group1 |
| 2038 | |
| 2039 | 3) But breakpoint names are also entities in their own right, and can be |
| 2040 | configured with all the modifiable attributes of a breakpoint. Then when you |
| 2041 | add a breakpoint name to a breakpoint, the breakpoint will be configured to |
| 2042 | match the state of the breakpoint name. The link between the name and the |
| 2043 | breakpoints sharing it remains live, so if you change the configuration on the |
| 2044 | name, it will also change the configurations on the breakpoints: |
| 2045 | |
| 2046 | (lldb) break name configure -i 10 IgnoreSome |
| 2047 | (lldb) break set -n myFunc -N IgnoreSome |
| 2048 | (lldb) break list IgnoreSome |
| 2049 | 2: name = 'myFunc', locations = 0 (pending) Options: ignore: 10 enabled |
| 2050 | Names: |
| 2051 | IgnoreSome |
| 2052 | (lldb) break name configure -i 5 IgnoreSome |
| 2053 | (lldb) break list IgnoreSome |
| 2054 | 2: name = 'myFunc', locations = 0 (pending) Options: ignore: 5 enabled |
| 2055 | Names: |
| 2056 | IgnoreSome |
| 2057 | |
| 2058 | Options that are not configured on a breakpoint name don't affect the value of |
| 2059 | those options on the breakpoints they are added to. So for instance, if Name1 |
| 2060 | has the -i option configured and Name2 the -c option, adding both names to a |
| 2061 | breakpoint will set the -i option from Name1 and the -c option from Name2, and |
| 2062 | the other options will be unaltered. |
| 2063 | |
| 2064 | If you add multiple names to a breakpoint which have configured values for |
| 2065 | the same option, the last name added's value wins. |
| 2066 | |
| 2067 | The "liveness" of these settings is one way, from name to breakpoint. |
| 2068 | If you use "break modify" to change an option that is also configured on a name |
| 2069 | which that breakpoint has, the "break modify" command will override the setting |
| 2070 | for that breakpoint, but won't change the value configured in the name or on the |
| 2071 | other breakpoints sharing that name. |
| 2072 | |
| 2073 | 4) Breakpoint names are also a convenient way to copy option sets from one |
| 2074 | breakpoint to another. Using the -B option to "breakpoint name configure" makes |
| 2075 | a name configured with all the options of the original breakpoint. Then |
| 2076 | adding that name to another breakpoint copies over all the values from the |
| 2077 | original breakpoint to the new one. |
| 2078 | |
| 2079 | 5) You can also use breakpoint names to hide breakpoints from the breakpoint |
| 2080 | operations that act on all breakpoints: "break delete", "break disable" and |
| 2081 | "break list". You do that by specifying a "false" value for the |
| 2082 | --allow-{list,delete,disable} options to "breakpoint name configure" and then |
| 2083 | adding that name to a breakpoint. |
| 2084 | |
| 2085 | This won't keep the breakpoint from being deleted or disabled if you refer to it |
| 2086 | specifically by ID. The point of the feature is to make sure users don't |
| 2087 | inadvertently delete or disable useful breakpoints (e.g. ones an IDE is using |
| 2088 | for its own purposes) as part of a "delete all" or "disable all" operation. The |
| 2089 | list hiding is because it's confusing for people to see breakpoints they |
| 2090 | didn't set. |
