• print_error - print message in red panel

system

system.copy-local-settings

system.copy-vscode-settings

Copies local template for vscode settings into .vscode folder

Settings:

• vs_code_settings_template path to settings template (Default: .vscode/recommended_settings.json)

system.chown

Change owner ship of project files to current user.

Shortcut for owning apps dir by current user after some files were generated using docker-compose (migrations, new app, etc).

system.create-tmp-folder

Create folder for temporary files(.tmp).

git

git.set-git-setting

Set git setting in config

git.setup

Preform setup of git:

• Install pre-commit hooks
• Set merge.ff
• Set pull.ff

Settings:

• merge_ff setting value for merge.ff (Default: false)
• pull_ff setting value for pull.ff (Default: only)

git.clone-repo

git.blame-copy

Command for creating copies of a file with git blame history saving.

Original script written in bash: https://dev.to/deckstar/how-to-git-copy-copying-files-while-keeping-git-history-1c9j

Usage:

  inv git.blame-copy <path to original file> <path to copy>,<path to copy>...

If <path to copy> is file, then data will be copied in it.

If <path to copy> is directory, then data will be copied in provided directory with original name.

Algorithm:

1. Remember current HEAD state
2. For each copy path: move file to copy path, restore file using checkout, remember result commits
3. Restore state of branch
4. Move file to temp file
5. Merge copy commits to branch
6. Move file to it's original path from temp file

Settings:

• copy_commit_template template for commits created during command workflow
• copy_init_message_template template for init message printed at command start

Template variables:

• action - The copy algorithm consists of several intermediate actions (creating temporary files, merging commits, etc.) The action variable stores the header of the intermediate action.
• original_path - Contains value of first argument of the command (path of original file that will be copied)
• destination_paths - Sequence of paths to which the original file will be copied
• project_task - project task that will be parsed from current git branch. If no task found in branch, then will be empty

Default values for templates:

• copy_commit_template:

  "[automated-commit]: {action}\n\n"
  "copy: {original_path}\n"
  "to:\n* {destination_paths}\n\n"
  "{project_task}"
