Created out of infuriating difficulty of creating symbolic links on windows Created out of infuriating difficulty of creating symbolic links on windows
## Custom syntax ## Instruction Formats
The tool works with "instructions" that describe symbolic links The tool supports two formats for defining symbolic links:
They are, in any form, \<source>,\<destination>,\<force?> ### 1. CSV Format (Legacy)
Simple comma-separated values with the format: `<source>,<destination>[,force][,hard][,delete]`
For example: For example:
`sync this,that` ```
source_path,target_path
source_path,target_path,true
source_path,target_path,true,true
source_path,target_path,true,true,true
```
It supports input of these instructions through: Or with named flags:
```
source_path,target_path,force=true,hard=true,delete=true
source_path,target_path,f=true,h=true,d=true
```
### 2. YAML Format (Recommended)
A more readable format using YAML:
```yaml
links:
- source: ~/Documents/config.ini
target: ~/.config/app/config.ini
force: true
- source: ~/Pictures
target: ~/Documents/Pictures
hard: true
force: true
- source: ~/Scripts/script.sh
target: ~/bin/script.sh
delete: true
```
Alternatively, you can use an array directly:
```yaml
- source: ~/Documents/config.ini
target: ~/.config/app/config.ini
force: true
- source: ~/Pictures
target: ~/Documents/Pictures
hard: true
```
## Input Methods
The tool supports input of these instructions through:
- Stdin - Stdin
- `echo "this,that" | sync` - `echo "this,that" | sync`
- Run arguments - Run arguments
- `sync this,that foo,bar "foo 2","C:/bar"` - `sync this,that foo,bar "foo 2","C:/bar"`
- Files - Files
- `sync -f <file>` - `sync -f <file>` (CSV format)
- Where the file contains instructions, one instruction per line - `sync -f <file.yaml>` or `sync -f <file.yml>` (YAML format)
- Where the file contains instructions, one per line for CSV or structured YAML
- Directories - Directories
- `sync -r <directory>` - `sync -r <directory>`
- This mode will look for "sync" files recursively in directories and run their instructions - This mode will look for "sync", "sync.yaml", or "sync.yml" files recursively in directories and run their instructions
## Options
- `force: true` - Overwrite an existing symbolic link at the target location
- `hard: true` - Create a hard link instead of a symbolic link
- `delete: true` - Delete a non-symlink file at the target location (implies `force: true`)
