Now it actually defaults to "a < b" comparison, instead of forcing you
to provide a trivial less-than comparator. Also you can pass in any
collection type that has .begin() and .end() and we'll sort it for you.
I've been wanting to do this for a long time. It's time we start being
consistent about how this stuff works.
The new convention is:
- "LibFoo" is a userspace library that provides the "Foo" namespace.
That's it :^) This was pretty tedious to convert and I didn't even
start on LibGUI yet. But it's coming up next.
As suggested by Joshua, this commit adds the 2-clause BSD license as a
comment block to the top of every source file.
For the first pass, I've just added myself for simplicity. I encourage
everyone to add themselves as copyright holders of any file they've
added or modified in some significant way. If I've added myself in
error somewhere, feel free to replace it with the appropriate copyright
holder instead.
Going forward, all new source files should include a license header.
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.
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.
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.
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.
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 :^)
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.
Hook this up in Terminal so that the '\a' character generates a beep.
Finally emit an '\a' character in the shell line editing code when
backspacing at the start of the line.
