# Screenshots with demos and scripts to generate them
|
|
|
|
The `demo_*.sh` scripts in this directory demo
|
|
various features of `jj`.
|
|
|
|
The `run_scripts.sh` script can be used to:
|
|
|
|
- Run them inside a standardized environment instead of the user's local
|
|
environment.
|
|
- Generate SVG and PNG images for the scripts.
|
|
|
|
The PNG images in the repo may be slightly older, as they take up more space in
|
|
the repo.
|
|
|
|
The SVG images have human-readable diffs, but may look different on different
|
|
computers with different fonts installed.
|
|
|
|
## Running `run_scripts.sh`
|
|
|
|
This requires ImageMagick and `term-transcript-cli` to be installed. See
|
|
`run_scripts.sh`'s error messages for some more details. On Debian Linux, it
|
|
also seems helpful to `sudo apt install inkscape`; ImageMagick seems to use
|
|
either Inkscape itself or some dependency of it.
|
|
|
|
One way to make all the images and check the output is:
|
|
|
|
```shell
|
|
cd demos
|
|
./run_scripts.sh demo_*.sh |less
|
|
```
|
|
|
|
### A note on fonts
|
|
|
|
The exact PNG output depends on the fonts you have installed on your system.
|
|
|
|
The screenshots are usually generated on a Debian Linux system and use the "Fira
|
|
Code" font. It can be installed with `sudo apt install fonts-firacode`. It seems
|
|
to include all relevant Unicode symbols and be a little bolder and thus more
|
|
readable than the "Liberation Mono" font, which is used if Fira Code is not
|
|
installed. That font also works OK. See the CSS font specification in
|
|
`run_scripts.sh` for other fonts tried (especially when viewing SVGs on the
|
|
web). If none apply, the default `monospace` font will be used.
|
|
|
|
`convert -list Fonts` will list the fonts ImageMagick is aware of.
