${YELLOW}${BOLD}What's that?${NORMAL}
|

|
|
This script is designed to manage configuration files.
|
||
|
|
It has two modes of operation: ${BOLD}interactive${NORMAL} and ${BOLD}command line${NORMAL}.
|
||
|
|
|
||
|
|
To run the script in interactive mode run the script without arguments:
|
||
|
|
${BOLD}./confcore.sh${NORMAL}
|
||
|
|
|
||
|
|
To run the script in command line mode, use arguments according to the following scheme:
|
||
|
|
${BOLD}./confcore.sh${NORMAL} ${BLUE}${BOLD}<commands>${NORMAL} ${GREEN}${BOLD}<args>${NORMAL}
|
||
|
|
|
||
|
|
${BLUE}${BOLD}Commands:${NORMAL}
|
||
|
|
${BOLD} * conf-deploy${NORMAL} - deploy configs(create symlinks) from manifest file
|
||
|
|
${BOLD} * conf-delete${NORMAL} - delete symlinks
|
||
|
|
${BOLD} * about${NORMAL} - about this script
|
||
|
|
|
||
|
|
${GREEN}${BOLD}Args:${NORMAL}
|
||
|
|
${BOLD} * conf-deploy${NORMAL} - none
|
||
|
|
${BOLD} * conf-delete${NORMAL} - none
|
||
|
|
${BOLD} * about${NORMAL} - none
|
||
|
|
|
||
|
|
${YELLOW}${BOLD}Global variables:${NORMAL}
|
||
|
|
${BOLD}* CONFIGS_DIR${NORMAL} - sets the directory where the configs are stored. Default: \"configs\"
|
||
|
|
|
||
|
|
|
||
|
|
${YELLOW}${BOLD}Manifest file:${NORMAL}
|
||
|
|
The manifest file (MANIFEST by default), located in the ${BOLD}CONFIGS_DIR${NORMAL} directory, describes
|
||
|
|
the rules for creating symbolic links for configuration/dotfiles.
|
||
|
|
|
||
|
|
${BOLD}Syntax and example:${NORMAL}
|
||
|
|
|

+-----------------------------------------------------+
|
||
|
|
| # comment bla-bla-bla |
|
||
|
|
| \$HOME <- .zshrc .tmux.conf fuck-this-shit/.emacs.d |
|
||
|
|
| \$HOME/.config <- nvim |
|
||
|
|
+-----------------------------------------------------+
|
||
|
|
|
||
|
|
As we can see, our manifest file supports comments that start with the ${BOLD}\"#\"${NORMAL} character.
|
||
|
|
Next we see the expression for symlink creation, which starts with the directory where
|
||
|
|
the symlinks should be created, the special character combination ${BOLD}\"<-\"${NORMAL} to create a symbolic
|
||
|
|
link, and a list of configuration files for which the links should be created, separated by spaces.
|
||
|
|
In the left part of the expression it is allowed to use variables, for example \$HOME.
|
||
|
|
In the right part of the expression all paths are calculated relative to ${BOLD}CONFIGS_DIR${NORMAL}.
|
||
|
|
Strings not containing ${BOLD}\"<-\"${NORMAL} will be ignored.
