This add-on is based on the popular log viewer software called glogg.
Enables:
- Viewing huge files, especially logs, without performance or ram usage loss
- Monitoring changes in displayed files and dynamically extending the content
- File search
- Dynamic extension of search results with changes in files (new entries)
Requires @Push enabled for stable and comfortable work
FileViewer viewer = new FileViewer();
viewer.openFile(new File("...).toPath());
viewer.openFile(new File("...").toPath());
viewer.openFile(new File("...").toPath());
Since the extension uses default vaadin components, all used components have been made available for modification via getters.
If you want to display the entire log line without text-wrapping, you need to extend your component style file (frontend/your_theme_name/components/vaadin-grind.css) about this entry:
:host([theme~='log']) [part~='cell']:not([part~='details-cell']) {
white-space: break-spaces;
}
Add below styles to enable font resizing (frontend/your_theme_name/components/vaadin-grind.css
vaadin-grid{
--grid-row-height: 20px;
--grid-line-height: 20px;
--grid-font-size: 18px;
}
vaadin-grid:host([theme~='log']) [part~='cell'] {
min-height: var(--grid-row-height);
font-size: var(--grid-font-size);
line-height: var(--grid-line-height);
}
- You can disable/hide polling configuration and also search bar. To do that you have to pass configuration to the constructor of the FileViewer
FileViewer viewer = new FileViewer(new FileViewerConfig(){
@Override
public boolean pollingEnabled() {
return true;
}
@Override
public int pollingInterval() {
return 1;
}
@Override
public boolean searchViewVisible() {
return true;
}
@Override
public boolean fontResizeAllowed() {
return true;
}
});
