### Preview Files with Syntax Highlighting using Shell Script

Source: https://github.com/kazhala/dotbare/wiki/Custom-Scripts

This script provides a preview of files with syntax highlighting if compatible packages like 'bat' or 'highlight' are installed. It's designed to be invoked within the fzf preview argument and takes a filename and optional line number as input.

```shell
mydir="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"
find . -maxdepth 1 -type f | sed "s|\./||g" | fzf --multi --preview "${mydir}/preview.sh {}"
```

--------------------------------

### Integrate Dotbare with Existing Symlink Setup

Source: https://github.com/kazhala/dotbare/blob/master/README.md

Sets environment variables DOTBARE_DIR and DOTBARE_TREE to integrate Dotbare with an existing symlink or GNU stow setup. This allows Dotbare to recognize and manage dotfiles managed by other tools without a full migration.

```bash
# e.g. I have all my dotfiles stored in folder $HOME/.myworld and symlinks all of them to appropriate location.
# export DOTBARE_DIR="$HOME/.myworld/.git"
# export DOTBARE_TREE="$HOME/.myworld"
export DOTBARE_DIR=<Path to your .git location>
export DOTBARE_TREE=<Path to directory which contains all your dotfiles>
```

--------------------------------

### Install Tree Dependency on macOS

# if you are on macos
brew install tree
```

--------------------------------

### Get Modified Files using fzf with Customization

Source: https://github.com/kazhala/dotbare/wiki/Custom-Scripts

The `get_modified_file` function lists modified files in fzf, showing file changes in the preview. It supports filtering by modification status (all, staged, unstaged) and output format (name or raw with status). Multi-select is enabled by default. The example shows how to capture multiple selected file names into a bash array.

```bash
selected_files=()
while IFS= read -r line; do
  selected_files+=("${line}")
done < <(get_modified_file "select files to stage" "unstaged" "name")
```

--------------------------------

### Get Selected Git File Path using fzf

Source: https://github.com/kazhala/dotbare/wiki/Custom-Scripts

This function, `get_git_file`, presents all tracked dotfiles in fzf with file previews. It returns the selected file path. Arguments control the display format (full path or raw name) and whether multi-select is enabled. By default, it returns the full path and enables multi-select.

```bash
selected_files=$(get_git_file "select files to backup" "raw")
```

--------------------------------

### Alias dotbare command

Source: https://github.com/kazhala/dotbare/wiki/Tips-and-Tricks

Create a shorthand alias for the dotbare command to improve typing efficiency in the terminal.

```sh
alias dots=dotbare
```

--------------------------------

### Get Selected Commit Hash using fzf

Source: https://github.com/kazhala/dotbare/wiki/Custom-Scripts

This function, `get_commit`, lists all git commits through fzf, displaying commit information in the preview window. It returns the 7-character hash of the selected commit. An optional argument can be provided to customize the header message displayed in fzf.

```bash
selected_commit=$(get_commit "select a commit to foo boo")
```

--------------------------------

### Exclude dotbare directory from git

Source: https://github.com/kazhala/dotbare/wiki/Tips-and-Tricks

Add the dotbare directory to the global .gitignore to prevent recursion issues. The path must be relative to the DOTBARE_TREE.

```sh
echo ".cfg" >> $HOME/.gitignore
echo ".config/.cfg" >> $HOME/.gitignore
```

--------------------------------

### Get Selected Branch Name using fzf

Source: https://github.com/kazhala/dotbare/wiki/Custom-Scripts

The `get_branch` function allows users to select a git branch via fzf, with git log information displayed in the preview. It returns the name of the chosen branch. An optional argument can be used to set the fzf header message.

```bash
selected_branch=$(get_branch 'select a branch to checkout')
```

--------------------------------

### Get Selected Stash Identifier using fzf

Source: https://github.com/kazhala/dotbare/wiki/Custom-Scripts

This function, `get_stash`, lists all stashes and displays their diff against HEAD in the fzf preview window. It returns the identifier of the selected stash (e.g., `stash@{0}`). An optional argument can be provided to customize the fzf header message.

```bash
selected_stash=$(get_stash "select stash to delete")
```

--------------------------------

### Delete Git Branch via fzf Selection using Bash Script

Source: https://github.com/kazhala/dotbare/wiki/Custom-Scripts

This Bash script facilitates the deletion of Git branches, including remote branches, by first selecting the branch using fzf. It relies on helper scripts for setting variables and querying Git information. It requires Git to be installed and configured.

```shell
#!/usr/bin/env bash

mydir="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"
source "${mydir}"/../helper/set_variable.sh
source "${mydir}"/../helper/git_query.sh

selected_branch=$(get_branch 'select a branch to delete')

[[ -z "${selected_branch}" ]] && exit 1

remote_branch_regex="^remotes\/.*$"

if [[ "${selected_branch}" =~ $remote_branch_regex ]]; then
  read -r remote_name origin_name branch_name <<< $(
    echo "${selected_branch}" \
      | awk -F "/" '{ 
          remote=$1
          origin=$2
          sub($1 FS $2 FS, "")
          print remote " " origin " " $0
        }'
  )
  git --git-dir="${DOTBARE_DIR}" --work-tree="${DOTBARE_TREE}" push -d "${origin_name}" "${branch_name}"
else
  git --git-dir="${DOTBARE_DIR}" --work-tree="${DOTBARE_TREE}" branch -D "${selected_branch}"
fi
```

--------------------------------

### Initialize Dotbare Bare Repository

Source: https://github.com/kazhala/dotbare/blob/master/README.md

Initializes a new bare repository for managing dotfiles using the 'dotbare finit' command. By default, it sets up the repository in $HOME/.cfg.

```bash
dotbare finit
```

--------------------------------

### Complete Migration to Dotbare Bare Repository

Source: https://github.com/kazhala/dotbare/blob/master/README.md

Performs a complete migration to a Dotbare bare repository by initializing it with a remote URL. This command replaces existing symlinks with the original files and creates a bare repository. Use with caution and test thoroughly.

```bash
# dotbare will replace all symlinks with the original file and a bare repository will be created at $DOTBARE_DIR
dotbare finit -u [URL]
```

--------------------------------

### Sourcing Git Query Helper Functions

Source: https://github.com/kazhala/dotbare/wiki/Custom-Scripts

This code demonstrates how to source the `git_query.sh` helper file within a bash script. This makes all the git information querying functions available for use in the script, which are utilized by dotbare for fzf integration.

```bash
source "${mydir}"/../helper/git_query.sh
```

--------------------------------

### Search Files and Directories using Shell Script

Source: https://github.com/kazhala/dotbare/wiki/Custom-Scripts

This script searches for files or directories within the current directory up to one level deep. It requires sourcing a helper script and takes a single argument ('f' for file, 'd' for directory). It outputs the selected file path.

```shell
source "${mydir}"/../helper/search_file.sh

selected_files= ()
while IFS= read -r line; do
  selected_files+=("${line}")
done < <(search_file 'f')
```

--------------------------------

### Configure Dotbare for Existing Git Bare Repository

Source: https://github.com/kazhala/dotbare/blob/master/README.md

Sets environment variables DOTBARE_DIR and DOTBARE_TREE to inform Dotbare about the location of an existing git bare repository and the directory containing dotfiles. This is used for migrating from a normal git bare repository.

```bash
export DOTBARE_DIR="$HOME/.cfg"
export DOTBARE_TREE="$HOME"
```

--------------------------------

### Configure Gitignore for Scripts Folder (Shell)

Source: https://github.com/kazhala/dotbare/blob/master/CONTRIBUTING.md

Shows how to configure the `.gitignore` file to ignore all files within the `scripts/` directory except for specific essential scripts like `fadd`, `fbackup`, and user-defined new scripts. This ensures that only intended scripts are tracked by Git.

```shell
# ignore everything in scripts folder except the !scripts/fadd etc
scripts/*
!scripts/fadd
!scripts/fbackup
....
!scripts/your new script
```

--------------------------------

### Improve Help Message Output Efficiency (Shell)

Source: https://github.com/kazhala/dotbare/blob/master/CONTRIBUTING.md

Demonstrates an optimization for displaying help messages in dotbare. Previously, messages were printed using multiple `echo -e` commands. This snippet shows the improved version where all messages are combined into a single `echo -e` command, reducing unnecessary invocations.

```shell
# Before
echo -e "usage: ...\n"
echo -e "foo boo\n"
echo -e "Optional arguments: ...\n"

# After
echo -e "usage: ...

foo boo

Optional arguments: ..."
```

--------------------------------

### Enable Dotbare Command Completion

Source: https://github.com/kazhala/dotbare/wiki/Completion

Activates completion for dotbare subcommands. In Zsh, this requires compinit to be loaded first, while in Bash, it accepts an optional argument to support aliased command names.

```zsh
autoload -U compinit && compinit
_dotbare_completion_cmd
```

```bash
_dotbare_completion_cmd
# For aliased commands
_dotbare_completion_cmd config
```

--------------------------------

### Enable Git Command Completion

Source: https://github.com/kazhala/dotbare/wiki/Completion

Activates git-specific completion for dotbare. Note that this functionality is limited as the underlying git completion script is unaware of custom DOTBARE_DIR or DOTBARE_TREE variables.

```zsh
_dotbare_completion_git
```

```bash
_dotbare_completion_git
# For aliased commands
_dotbare_completion_git config
```

--------------------------------

### Add Dotfiles with Dotbare

Source: https://github.com/kazhala/dotbare/blob/master/README.md

Adds dotfiles or directories to the Dotbare repository for tracking. It supports adding individual files or entire directories using flags like '-f' for files and '-d' for directories.

```bash
dotbare fadd -f
# or
dotbare add [FILENAME]

# add entire repository like .config directory
dotbare fadd -d
# or
dotbare add [DIRECTORY]
```

--------------------------------

### Add Dotbare to PATH and Create Alias

Source: https://github.com/kazhala/dotbare/blob/master/README.md

Adds the dotbare executable directory to the system's PATH for easy access and optionally creates an alias for the 'dotbare' command. This is for POSIX-compliant shells.

```bash
# This is only an example command for posix shell
# If you are on fish, use the fish way to add dotbare to your path
export PATH=$PATH:$HOME/.dotbare

alias dotbare="$HOME/.dotbare/dotbare"
```

--------------------------------

### Mocking fzf invocation in Bats tests

Source: https://github.com/kazhala/dotbare/blob/master/tests/README.md

This snippet demonstrates how to mock the 'fzf' command within a bats test. By exporting the test directory to the PATH, the test can execute a local mock 'fzf' instead of the system-wide one. This allows for asserting that 'fzf' is called with the correct arguments, such as '--multi --preview' and 'tree -L 1 -C --dirsfirst {}'.

```shell
#!/usr/bin/env bats

stage_selected_dir() {
  export PATH="${BATS_TEST_DIRNAME}:$PATH"
  bash "${BATS_TEST_DIRNAME}"'/../dotbare' fadd --dir
}
```

```shell
if [[ "$*" =~ '--multi --preview ' ]] && [[ "$*" =~ "tree -L 1 -C --dirsfirst {}" ]]; then
  # dotbare fadd --dir -- "./fadd.bats" @test "fadd stage selected dir"
  echo "fadd_stage_dir"
fi
```

```shell
#!/usr/bin/env bats

@test "fadd stage selected dir" {
  run stage_selected_dir
  # we could assert if fzf is actually being invoked correctly
  # in this case, it's supposed to search directory and using tree to provide preview
  [[ "${output}" =~ "add fadd_stage_dir" ]]
}
```

--------------------------------

### Bats unit tests for 'flog help' and 'flog reset'

Source: https://github.com/kazhala/dotbare/blob/master/tests/README.md

This code provides bats unit tests for the 'flog help' and 'flog reset' commands of the dotbare project. The 'flog reset' test utilizes the PATH override method to mock 'fzf' interactions, asserting that the output contains 'reset --flog_reset'. The 'flog help' test simply checks for a successful exit status and verifies the first line of the output.

```shell
#!/usr/bin/env bats

help() {
  bash "${BATS_TEST_DIRNAME}"'/../dotbare' flog -h
}
reset() {
  export PATH="${BATS_TEST_DIRNAME}:$PATH"
  bash "${BATS_TEST_DIRNAME}"'/../dotbare' flog --reset -y
}

@test "flog help" {
  run help
  [ "${status}" -eq 0 ]
  [ "${lines[0]}" = "Usage: dotbare flog [-h] [-r] [-R] [-e] [-c] [-y] ..." ]
}
@test "flog reset" {
  run reset
  [[ "${output}" =~ "reset --flog_reset" ]]
}
```

--------------------------------

### Mocking fzf for 'flog reset' in Bats tests

Source: https://github.com/kazhala/dotbare/blob/master/tests/README.md

This snippet shows how to mock the 'fzf' command for the 'flog --reset' functionality in bats tests. Similar to other mocks, it involves exporting the test directory to the PATH. The mock 'fzf' executable checks for specific arguments like '--header=select a commit' and 'show --color' to simulate the correct invocation and returns a specific string '--flog_reset'.

```shell
if [[ "$*" =~ '--header=select a commit' ]] && [[ "$*" =~ "show --color" ]]; then
  # dotbare flog --reset -y -- "./flog.bats" @test "flog reset"
  echo "--flog_reset"
fi
```

--------------------------------

### Commit and Push Dotfiles with Dotbare

Source: https://github.com/kazhala/dotbare/blob/master/README.md

Commits the staged dotfile changes and pushes them to a remote repository. This involves setting up a remote origin and performing the push operation.

```bash
dotbare commit -m "First commit"
dotbare remote add origin [URL]
dotbare push -u origin master
```
