- Add thread/exit to kill the current thread.
- Add global lock aroung custom getline and add atexit handler
- to prevent any possible issues when exiting program.
- Allow sending stderr, stdout, and stdin over thread.
Required a few changes to APIs, namely janet_root_fiber()
to get topmost fiber that is active in the current scheduler.
This is distinct from janet_current_fiber(), which gets the bottom
most fiber in the fiber stack - it might have a parent, and so cannot
be reliably resumed.
This is the kind of situation that makes symmetric coroutines more
attractive.
This way we can support fewer build configurations. Also, remove
all undefined behavior due to use of memcpy with NULL pointers. GCC
was exploiting this to remove NULL checks in some builds.
* I deleted Alt-H and Alt-L because Ctrl-F and Ctrl-B serve the same
roles.
* Ctrl-W, Alt-D, Alt-F, and Alt-B behave more similarly to the same
key bindings on GNU readline.
* Improved documentation of REPL keybindings on man page.
* Home and End keys now work on more terminal environments.
* Removed bindings for `Esc OH` and `Esc OF` because andrewchambers
doesn't need those bindings and the bindings don't seem to make much
sense for Home and End. `Esc O` is Single Shift Select of G3 Character
Set in xterm. https://invisible-island.net/xterm/ctlseqs/ctlseqs.html
Also add a few ctrl sequences from readline, and
ignore unknown ctrl sequences.
Address #264
Adds Ctrl-n, Ctrl-p, and Ctrl-w
Ignores unknown ctrl sequences
No alt-* sequences yet.
This allows easy builds of the full interpreter with no
build system.
1. Get janet.c, janet.h, janetconf.h, and shell.c in a directory. Edit
janetconf.h as desired.
2. gcc shell.c janet.c -lm -ldl -O2 -o janet (on GNU-Linux for example)
3. ./janet -h (Yay!)
This makes it easier to get the CLI functionality when
embedding Janet, although the main reason is the init script
is now pre-compiled to bytecode when generating the boot image.
Flychecking will now work correctly with arity checking, and
will better handle imports. Well structured modules should interact
cleanly with the flychecker in a mostly safe manner, but maliciously
crafted modules can execute arbitrary code. As such, the flychecker is
not a good way to validate completely untrusted modules.
We also extend run-context with an :evaluator option to replace
:compile-only. This is more flexible and allows users to create their
own flychecker like functionality.
This should be friendlier to most users. It does, however, mean
we lose range information. However, range information could be
recovered by re-parsing, as janet's grammar is simple enough to do this.
