I'm writing a Bash script to convert Arch Linux packages into a format for a package manager I'm writing, and I have to convert some metadata files into file format .toml. Previously, I've been using sed, but I just need something I can implement into a Bash script. The conversion should look like shown below. Input:

... other stuff ...
depends = "some-dependency"
depends = "another-dependency"
depends = "yet-another-dependency"

Output:

... other stuff already converted ...
depends = [ "some-dependency", "another-dependency", "yet-another-dependency" ]

I have a TOML file in the following format (categories may have any name, the sequential numbering is just an example and not guaranteed):

[CATEGORY_1]
A=1
B=2

[CATEGORY_2]
C=3
D=4

E=5

...

[CATEGORY_N]
Z=26

What I want to achieve is to retrieve the text inside a given category. So, if I specify, let's say, [CATEGORY_1] I want it to give me the output:

A=1
B=2

I tried using grep to achieve this task, with the z flag, so it could interpret newlines as null-byte characters and using this regular expression:

(^\[.*])             # Match the category 
  ((.*\n*)+?         # Match the category content in a non-greedy way
    (?=\[|$))        # Lookahead to the start of other category or end of line

It wasn't working unless I removed the ^ at beginning of the expression. However, if I do this, it will misinterpret loose pairs of brackets as a category. Is there a way to do it correctly? If not with grep, with other tool, such as sed or awk.

I need to read and modify a single file (pcmanfm.conf) in the current directory. I tried

$ augtool -At "Toml.lns incl $(pwd)/pcmanfm.conf" -I lenses/ print /files
/files

but it does not work. toml.aug (on /usr/share/augeas/lenses/dist/toml.aug) starts with

(*
Module: Toml
  Parses TOML files

Author: Raphael Pinson 
...

so I believe I put the name of the lens correctly (Toml.lns). The same setup works well if I parse file of a different type, e.g.

$ augtool -At "Shellvars.lns incl /tmp/vars.sh" -I lenses/ print /files
/files
/files/tmp
/files/tmp/vars.sh
/files/tmp/vars.sh/TESTINT = "2"
/files/tmp/vars.sh/TESTSTR = "\"FF\""

I've posted the same question on https://github.com/hercules-team/augeas/issues/699 in case it is a bug in Augeas. The file I try to parse has the following content:

[config]
bm_open_method=0

[volume]
mount_on_startup=1
mount_removable=1
autorun=1

[ui]
always_show_tabs=0
max_tab_chars=32
win_width=1916
win_height=1149
splitter_pos=150
media_in_new_tab=0
desktop_folder_new_win=0
change_tab_on_drop=1
close_on_unmount=1
focus_previous=0
side_pane_mode=places
view_mode=compact
show_hidden=0
sort=name;ascending;
toolbar=newtab;navigation;home;
show_statusbar=1
pathbar_mode_buttons=0

I want to add/replace one value in the [ui] section.

I need to fetch this image for podman but there is a problem on *registry.conf* podman gives error

podman run --name myfirstcontainer -it  -v /home/jhon:/data:Z manjarolinux/base
Error: error loading registries configuration "/etc/containers/registries.conf": toml: cannot load TOML value of type map[string]interface {} into a Go slice

my registry adjust
