This change does several things. First, and most important, it allows dumping the "n" most recent stack frames on each debug() call. Second, it demangles the C++ symbols. Third, it prepends each debug() message with the debug level. Unrelated to the above I've replaced all `assert(!is_forked_child());` statements with `ASSERT_IS_NOT_FORKED_CHILD()` for consistency.

\subsection fish-description Description
|
|
|
|
`fish` is a command-line shell written mainly with interactive use in mind. The full manual is available <a href='index.html'>in HTML</a> by using the <a href='#help'>help</a> command from inside fish.
|
|
|
|
The following options are available:
|
|
|
|
- `-c` or `--command=COMMANDS` evaluate the specified commands instead of reading from the commandline
|
|
|
|
- `-d` or `--debug-level=DEBUG_LEVEL` specify the verbosity level of fish. A higher number means higher verbosity. The default level is 1.
|
|
|
|
- `-i` or `--interactive` specify that fish is to run in interactive mode
|
|
|
|
- `-l` or `--login` specify that fish is to run as a login shell
|
|
|
|
- `-n` or `--no-execute` do not execute any commands, only perform syntax checking
|
|
|
|
- `-p` or `--profile=PROFILE_FILE` when fish exits, output timing information on all executed commands to the specified file
|
|
|
|
- `-v` or `--version` display version and exit
|
|
|
|
- `-D` or `--debug-stack-frames=DEBUG_LEVEL` specify how many stack frames to display when debug messages are written. The default is zero. A value of 3 or 4 is usually sufficient to gain insight into how a given debug call was reached but you can specify a value up to 128.
|
|
|
|
The fish exit status is generally the exit status of the last foreground command. If fish is exiting because of a parse error, the exit status is 127.
