In order to allow the execution of commands before dropping to an
interactive prompt, a new switch, '-C' or '--init-command' has been
added to those switches that we accept.
The documentation has been updated correspondingly.
The original code only supported a single command list to be executed,
and this command list terminates the shell when it completes. To allow
the new command list to preceed the original one, both have been
wrapped in a new container class 'command_line_switches_t'. This is
then passed around in place of the list of strings we used previously.
I had considered moving the interactive, login and other command line
switch states into this container, but doing so would change far more
of the code, moving the structure to be available globally, and I
wasn't confident of the impact. However, this might be a useful thing
to do in the future.
A new function, run_command_list, was lifted from the prior execution
code, and re-used for both the initial command and the regular command
execution.
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.
Completely fixes#1557 and the underlying Doxygen changes that caused
it. Should make fish docs simpler and more robust, more consistent and
generally prettier.
todo:
- trap unmarked text as arguments in context
- test & fix sed portability - see in particular. (so far tested on BSD
(Mac) and GNU sed).
- test Makefile changes
- last round of aesthetic changes and getting that ascii fish in there…
Rework for Doxygen >1.8. Moved large parts of the documentation to a
simplified format, making use of Markdown enhancements and fixing bad
long options.
Large list of changes, including formatting and typos for most commands.
More substantive changes have been made to alias, bind, block, break,
builtin, case, cd, commandline, count, else, emit, fish_config, funced,
function, functions, history, math, mimedb, nextd, not, popd, prevd,
pushd, pwd, random, read, set, set_color, switch, test, trap, type,
ulimit, umask, and while.
