nerdconvert

Convert nerd-font-icons to SVG / JSON / ESModule / CSV

The script will extract paths, viewbox, code, name, glyphname, glyph, svgfile from nerd-fonts iconfont/css and converts it to SVG, JSON, EcmaScript Module and CSV.

The exported JSON, ESModule directory and CSV file respectivly contain all the data needed to dynamically create <svg>-Tags with JavaScript.

Usage

If all the dependencies are installed you can simply run:

python nerdconvert.py --output json nerdfonts.json

This will create a nerdfonts.json file in the current directory.

The file contains an array of objects with all the extracted fields.

// nerdfonts.json
[
    // ...
    {
        "code": "26a1",
        "name": "oct-zap",
        "glyphname": "zap",
        "glyph": "⚡",
        "svgfile": "/tmp/nerdfonts_svg/26a1.svg",
        "viewbox": "-10 0 1300 2048",
        "paths": [
            "M1280 827l-1152 1152l384 -896h-512l1152 -1152l-384 896h512z"
        ]
    },
    // ...
]

Output options

The output option --output FORMAT FILEPATH or -o FORMAT FILEPATH can be used multiple times and specify a export target.

FORMAT can be set to json, es, csv or svg

FILEPATH specifies a file or directory. If no fileextension (.json | .csv | .svg) a directory is assumed and a default filename is used.

For formats that generate one file per icon (svg) placeholders in the form of {FIELD[:MODIFIER[:...]]} can be used to create meaningful filenames.

(See fields and modifiers for more details)

Example

python nerdconvert.py -o svg svgfiles/{name:camelcase}_{code}.svg

Will create files like octZap_26a1.svg in a directory called svgfiles

Fields

The --fields FIELD[:REPLACEMENT[:MODIFIER]] option specifies one or more fields included in the output. If not specified all fields are included.

FIELD one of the following field names:

paths string[] of svg paths
viewbox string svg viewBox
code string unicode codepoint
name string name extracted from nerdfont-icons css classnames
glyphname string iconname extracted from the font file
glyph string actual unicode character
svgfile string filepath to the corresponding *.svg-file

REPLACEMENT new fieldname the field sould be exported as.

MODIFIER modifies the field value. Can be set to:

camelcase make value camelcase
upper make value uppercase
lower make value lowercase

Exmaple

python nerdconvert.py --fields name name:icon:camelcase glyph:unicodechar \
        --output json nerdfont_icons.json

Will create:

// nerdfont_icons.json 
[
    // ...
    { "name": "oct-zap", "icon": "octZap", "unicodechar": "⚡" },
    // ...
]

Filter

The --filter FIELD REGEX option specifies filters to narrow down the the exported record. The record will only be exported if the REGEX (regular expression) matches the FIELD-value.

(See fields and python regular expressions for more details)

Example

python nerdconvert.py --filter name '^mdi' --filter \
        --output json material_icons.json

Will create material_icons.json that contains only the Material Design Icons.
