Instead of directly manipulating LDFLAGS, set LIB_DEPS in each
subdirectory Makefile listing the libraries needed for
building/linking such as "LIB_DEPS = Core GUI Draw IPC Core".
This adds each library as an -L and -l argument in LDFLAGS, but
also adds the library.a file as a link dependency on the current
$(PROGRAM). This causes the given library to be (re)built before
linking the current $(PROGRAM), but will also re-link any binaries
depending on that library when it is modified, when running make
from the root directory.
Also turn generator tools like IPCCompiler into dependencies on the
files they generate, so they are built on-demand when a particular
directory needs them.
This all allows the root Makefile to just list directories and not
care about the order, as all of the dependency tracking will figure
it out.

Allow everything to be built from the top level directory with just
'make', cleaned with 'make clean', and installed with 'make
install'. Also support these in any particular subdirectory.
Specifying 'make VERBOSE=1' will print each ld/g++/etc. command as
it runs.
Kernel and early host tools (IPCCompiler, etc.) are built as
object.host.o so that they don't conflict with other things built
with the cross-compiler.

Pushing the TAB key in the shell now prints suggestions to terminal.
This makes it easier to the user to actually see what files are
available before executing the command they currently have typed.

If the cursor is in front of a token that is not the first token, we try
to split it on the last slash. If there is a slash, the first part is
the directory to search and the second part is the token to complete.
If there is no slash, we search the current directory and use the entire
token for completion.
If we find a single match and it's a directory, we add a slash. If it's
a normal file, we add a space, unless there already is one.
Also renamed cut_mismatching_chars() parameters to be more appropriate.
|
|
A space is added if only one match is found, but we avoid adding
redundant spaces.
We complete "empty" tokens, i.e. when the cursor is at the start of the
line or in front of a space. For example:
mkdir test
cd test
touch test
chmod +x test
export PATH=/home/anon/test
Now if you press tab, or space and then tab, you will get "test". Notice
that you also get a space.
Completion is now done relative to the cursor. You can enter two words
and then go back and complete the first one.
|
|
This patch just factors out the procedure of adding characters at the
cursor position. It makes tab completion code much nicer.

I prefer String::format over StringBuilder here.
Also simplified a weird continue statement.
|
|
Using int was a mistake. This patch changes String, StringImpl,
StringView and StringBuilder to use size_t instead of int for lengths.
Obviously a lot of code needs to change as a result of this.

If we can't find an executable to exec() after forking, we don't want
to run the atexit() handlers in the child process. Just use _exit()
instead to avoid this.
This was causing us to write out the shell history to ~/.history every
time a "command not found" error was printed.
|
|
This patch reduces the O(n) tab completion to something like O(log(n)).
The cache is just a sorted vector of strings and we binary search it to
get a string matching our input, and then check the surrounding strings
to see if we need to remove any characters. Also we no longer stat each
file every time.
Also added an #include in BinarySearch since it was using size_t. Oops.
If `export` is called, we recache. Need to implement the `hash` builtin
for when an executable has been added to a directory in PATH.

In other words, if the user presses EOF (normally Ctrl+D), we now print
out "<EOF>" and exit the shell without error.
Fixes #701.
|

Previously, we did not properly restore termios settings
after running built-in commands. This has been fixed
by ensuring that we only change the termios settings
when we are forking a child process.
|
|
Shell.cpp uses its own line discipline which handles
echoing and line editing. Because of this we disable
ICANON and ECHO so that we don't get duplicate characters
or weird line editing errors.
We also revert these settings just before running a command.
This is so that commands may run with proper line editing
and echoing.

We had two ways to get the data inside a ByteBuffer. That was silly.
|
|
|
|
|
|
This patch adds a function to LineEditor that takes the current shell
buffer, searches PATH for the first program that starts with that
buffer and then compares that to any other programs starting with the
buffer to remove any mismatching characters off the end. The result is
appended to the buffer.
This may be faster with a data structure but that seems overkill.

Fixed a few issues with both `pushd` and `popd`. There was a few
typos etcetera causing it to behave errantly in certain situations.
|
|
Added a few builtin functions to the shell to make navigating a bit
easier in the terminal.
`pushd` allows a user to "push" the current directory to the directory
stack, and then `cd` to the new directory.
`popd` allows the used to take the directory on the top of the stack
off before `cd`'ing to it.
`dirs` gives the state of the current directory stack.
This is only a partial implementation of the `bash` version
(gnu.org/software/bash/manual/html_node/Directory-Stack-Builtins.html)
, and doesn't include any of the +N or -N commands as of yet.
|

This patch allows passing a script as an argument to the Shell program.
We will read the specified line by line and pass them through the Shell
command interpreter.
This is not very powerful, but it's a start :^)

This was a workaround to be able to build on case-insensitive file
systems where it might get confused about <string.h> vs <String.h>.
Let's just not support building that way, so String.h can have an
objectively nicer name. :^)

It's not safe to return a CFile by-value. CFile is a CObjects and they
are honestly not very good at being values..
|
|
|
|
When we only want to read the file, we should open it for reading.
|
|
By pressing ctr-e/a the cursor goes to the end/beginning of the current line.

It was kinda unpleasant to always see "So-and-so exited with status 123."
|
|
This looks a little nicer than 'execvp(cmd): No such file or directory'
|
|
Make LineEditor::get_line() responsible for printing the prompt. That way
we can re-prompt after clearing the screen on ^L.
This makes the Serenity Terminal feel a little bit more like home :^)
|
|
This makes waitpid() return when a child process is stopped via a signal.
Use this in Shell to catch stopped children and return control to the
command line. :^)
Fixes #298.

When resizing the terminal, we now clear the entire current line and reset
the shell's LineEditor input state. This makes it look and feel kinda the
same as xterm.
Fixes #286.

This should make you think twice before trying to use the const char* from
a StringView as if it's a null-terminated string.

A glob has to be resolved against the directory corresponding to
the part of the path it is found in, not the current directory.
For example, in /usr/i*/AK/, the glob has to be resolved inside
/usr. Moreover, an argument can contain more than one glob, such
as /u*/*/?, in which case they have to be resolved recursively.
In case a glob matches nothing, the argument should be used as is.

After reading a bunch of POSIX specs, I've learned that a file descriptor
is the number that refers to a file description, not the description itself.
So this patch renames FileDescriptor to FileDescription, and Process now has
FileDescription* file_description(int fd).
