v0.3.10

v0.3.10

got some envs

• smalloc is a libc-independent memory allocator, using mmap (may be used freely in other projects, I reccomend fun projects only. It is a very very basic algorithm and may cause high fragmentation and poor performance overall. However, we're only having some fun huh?)

• smalloc is used to fully implement a "sysh" environment support

• new "syntax" allows to set variables (already set and new ones, no unset)

$ % CC = gcc
$ %
<number of set env vars>
$ % new = var_set
$ envctl unset new

to unset a variable use the long envctl unset, using % VAR = will lead to segv

• Executable size:

> ldd sysh
	not a dynamic executable
> ls -lah sysh
-rwxr-xr-x 1 ssynx ssynx 16K  1 apr 00.20 sysh*
> strip sysh
> ls -lah sysh
-rwxr-xr-x 1 ssynx ssynx 8,6K  1 apr 00.20 sysh*

Minor but important bugfix

• sysh_getstatus now provides exit status for whatever program you run
• previously, could not detect correctly a segmentation fault (fixed)
• "sysh version 0.3.1-emma" banner

Still dedicated to her, we do it for every 0.3.z release ;)

v0.3.0-emma

• Provided implementation for execvp
• sysh_getstatus command to get return code on internal builtins and/or segfaults (no process exit code)
  NOTE:
  • using sysh_getstatus command won't alter current status
  • launching programs won't alter current status
    In general, all those program that won't change the last operation status.
