What is groff?

Groff (GNU troff) is a typesetting system that reads plain text mixed with formatting commands and produces formatted output. Output may be PostScript or PDF, html, or ASCII/UTF8 for display at the terminal.

Yes, i will give it a try on Monday

Jh Ony:
I have a string like this
newbode-5679.xml.bzip2.html

I want to the extract all the strings before the “.html” extension

Can anyone help me on this

you wanna use grep or is it inside a bash script?

are the strings in a file or in a variable?

we need a bit more context

~ ❯ var=’newbode-5679.xml.bzip2.html’
~ ❯ echo ${var%.html}
newbode-5679.xml.bzip2
~ ❯

I now just assumed you were talking about variables

but there some more ways

echo ${var%.html}
echo ${var:0:(-5)}

echo `expr “$var” : ‘(.*).html$’`
echo $(expr “$var” : ‘(.*).html$’)

for whatever reason I’m not able to make it work with “expr match”

Thank you so much it works fine

less elegant, but still working:

echo “$var” | sed s/.html$//g

this is probably a lua question more than anything

i’m setting up my neovim config, and i’m thinkking it’s dumb to have redundant .setup() lines

is it valid in lua to call for unexisting key’s values of a table?

so i could set cmd = myopts_cmds[lsp]

looks like it works fine 🙂

but why not in the Vim group?

Does anyone know which editor is this one?

I can tell it’s not Vim

Midnight commander’s coolEdit

Thanks to the search I’ve found devc++ and turboc ones, sadly the first one is only aimed for windows machines

cuz even though the context was nvim, the question was about lua

but either would work i guess

how old are these editors? 🤔

you will get nil

unless you use a metatable

t={}
print(t.foo)
prints nil

Soviet union era hehe. But they look so cool
