In harveyl888/progressList: Status of sequential tasks

progressList

progressList is a simple prototype for a progress list for shiny. The concept is straightforward - break a complex process down into a series of subprocesses and provide feedback on the status of each. The subprocesses can be assigned to one of five states:

• active
• completed
• waiting
• inactive
• failed

Once a subprocess finishes or its state changes it can be updated in the list.

Usage

Use in a shiny app. progressList creates a new list (ui) and progUpdate and progUpdateList can be used to update the state of a subprocess (server).

progressList('progresslist1', prog.labels, prog.status)

where prog.labels is a list of labels, one for each subprocess and prog.status is a list of states (see above).

a subprocess state can be updated using

progUpdate(session, value, newstatus)

where value is the label text and newstatus is the new status to assign.

A number of subprocesses can be updated using

progUpdateList(session, label, status)

for example: progUpdateList(session, c('label 1', 'label 2', 'label 3'), c('active', 'inactive', 'inactive'))

Still to do

This is just a prototype. There is still lots to do.
