Use mutool draw for previewing PDFs #494
Comments
|
PDF previews would allow me to use broot as my main file browser, I hope it can be added! In addition to mutool, the Kitty icat method may be of interest. It uses ImageMagick to open both images and pdfs. (For a pdf, one generally needs a white background.) |
Just discovered Broot. Amazing application. PDF previews are literately the only missing feature. |

This allows defining file transformations that are applied to files before preview.
The default conf has 2 examples: previewing PDF and beautifying JSON:
```Hjson
preview_transformers: [
# Use mutool to render any PDF file as an image
# In this example we use placeholders for the input and output files
{
input_extensions: [ "pdf" ] // case doesn't matter
output_extension: png
mode: image
command: [ "mutool", "draw", "-o", "{output-path}", "{input-path}" ]
}
# Use jq to beautify JSON
# In this example, the command refers to neither the input nor the output,
# so broot pipes them to the stdin and stdout of the jq process
{
input_extensions: [ "json" ]
output_extension: json
mode: text
command: [ "jq" ]
}
]
```
PDF preview:
JSON beautification (the original file has no space nor new line):

MuPDF's
mutool drawcommand produces a decently high-resolution image form of a PDF. It can be specified to only produce an image of the first page, which would be nice for previewing PDFs.Quick demo (after installing MuPDF):
$ mutool draw -o pdf-preview.png julia-1.5.0.pdf 1 # can add 2>/dev/null page julia-1.5.0.pdf 1 $ kitty +kitten icat pdf-preview.pngOr directly through stdout:
