This is a simple random ID generator. It generates random IDs given a specificed pattern.
usage: make_random_id.py [-h] [-i INPUT | -n NUMBER] [-x EXCLUDE_LIST] -o
OUTPUT -p PATTERN [--no_head]
Make random id
optional arguments:
-h, --help show this help message and exit
-i INPUT, --input INPUT
Input file. One random id will be generated per line
-n NUMBER, --number NUMBER
Number of random id to create
-x EXCLUDE_LIST, --exclude_list EXCLUDE_LIST
A file containing a list of IDs to exclude, i.e.
previous IDs to avoid duplication
-o OUTPUT, --output OUTPUT
Output file
-p PATTERN, --pattern PATTERN
Pattern, like "AA_@3xLU@-@2xD@"
--no_head Input file has no header and no header in outputThe pattern is a string that can contain any combination of characters, but not spaces. Random elements within the string are defined between @ characters.
Random elements are composed by:
- a number defining the number of random char to generate
- "x" char
- a tag defining the set of chars to use
For example, @3xLUP@ will generate 3 random uppercase letters
The following tags are allowed:
| Tag | Description |
|---|---|
| LUP | Uppercase letters |
| LLOW | Lowercase letters |
| L | Letters (mixed upper and lowercase) |
| D | Digits |
| LD | Uppercase letters + digits |
| Pattern | Example |
|---|---|
@3xLUP@-@2xD@ |
ABC-12 |
@3xLLOW@-@2xD@ |
abc-12 |
FIX_@2xLUP@@3xD@ |
FIX_AB123 |
FIX-@2xD@-@3xLUP@ |
FIX-12-DEF |
You can specify a list of IDs to exclude from the random generation usin --exclude_list. This accepts a text file with one ID per line.
This is useful if you want to generate new IDs for an existing project, but you want to avoid generating IDs that already exist.
