hi, rn i write my own text editor & copy features from other text editors,
one feature which i'm trying to copy is vim :py python sessions
try:
:py a=21
:py print(a)
it outputs:
21
if it keeps track of variables, it must have python running somewhere in a backgroud.
first i thought it forks python process, but running:
pstree <vim pid>
reveals that it does not have any children processes
vim───{vim}
so how do it do that?

I think Python is just being called as needed as functions.

elaborate?

Like it's not its own process, vim is just using it as a library.
The library has functions to set up a context and interpret lines of code.

i'm trying to confirm this right now, but it seems to be right, thanks
nm -A `which vim`
nm: /usr/bin/vim: no symbols
does nm needs executable to be compiled with debug symbols for it to work?

Don't use Linux much so no idea.

oh

On my Windows setup Python is dynamically linked though.

not on mine
ldd `which vim`
linux-vdso.so.1 (0x000079fdfad6c000)
libm.so.6 => /usr/lib/libm.so.6 (0x000079fdfa711000)
libncursesw.so.6 => /usr/lib/libncursesw.so.6 (0x000079fdfaccc000)
libacl.so.1 => /usr/lib/libacl.so.1 (0x000079fdfacc3000)
libgpm.so.2 => /usr/lib/libgpm.so.2 (0x000079fdfacbb000)
libc.so.6 => /usr/lib/libc.so.6 (0x000079fdfa520000)
/lib64/ld-linux-x86-64.so.2 => /usr/lib64/ld-linux-x86-64.so.2 (0x000079fdfad6e000)
yea its statically linked, you're right
and it even converts to using dynamic python lib when you're on windows in the soruce code so everything checks out
