Show tree of directory with files content

I would like to print out in terminal tree like one below:

$ tree -a
.
└── .git ├── branches ├── config ├── description ├── HEAD ├── hooks │   ├── applypatch-msg.sample │   ├── commit-msg.sample │   ├── fsmonitor-watchman.sample │   ├── post-update.sample │   ├── pre-applypatch.sample │   ├── pre-commit.sample │   ├── prepare-commit-msg.sample │   ├── pre-push.sample │   ├── pre-rebase.sample │   ├── pre-receive.sample │   └── update.sample ├── info │   └── exclude ├── objects │   ├── info │   └── pack └── refs ├── heads └── tags

With graphically presented content of all files ie it should like respectively?

.
└── .git ├── branches ├── config | | [core] | repositoryformatversion = 0 | filemode = true | bare = false | logallrefupdates = true | ├── description | | Unnamed repository; edit this file 'description' to name the repository. | ├── HEAD | | ref: refs/heads/master |

Is there an easy way to reach that?

I'm not aware of an easy way to do that, but I wrote a script that does something similar. Instead of a fancy tree listing like tree does, I made it flat, like find.

Output (in an empty git repo like your example):

.git/
.git/branches/
.git/config
==> start .git/config <==
[core] repositoryformatversion = 0 filemode = true bare = false logallrefupdates = true
==> end .git/config <==
.git/description
==> start .git/description <==
Unnamed repository; edit this file 'description' to name the repository.
==> end .git/description <==
.git/HEAD
==> start .git/HEAD <==
ref: refs/heads/master
==> end .git/HEAD <==
.git/hooks/
...

(The ==> ... <== header/footer is inspired by tail)

Here's the script:

#!/bin/bash
# Globs include hidden files, are null if no matches, recursive with **
shopt -s dotglob nullglob globstar
for file in **; do # Print filename with an indicator suffix for filetype ls --directory --classify -- "$file" filetype="$(file --brief --mime-type -- "$file")" # Only print text files if [[ $filetype == text/* ]]; then printf '==> %s %s <==\n' start "$file" cat --show-nonprinting -- "$file" printf '==> %s %s <==\n' end "$file" echo fi
done

It's not pretty, but it works. Color makes it pretty at least:

#!/bin/bash
shopt -s dotglob nullglob globstar
for file in **; do ls --directory --classify --color=yes -- "$file" filetype="$(file --brief --mime-type -- "$file")" # Only print text files if [[ $filetype == text/* ]]; then printf '\e[32m==> %s %s <==\e[m\n' start "$file" cat --show-nonprinting -- "$file" printf '\e[31m==> %s %s <==\e[m\n' end "$file" echo fi
done
