It's a JavaScript application that edits a text file in the browser.
The code takes in a structured text file ".inp" and outputs a modified version of that same file.
The main part of the code parses the text file, adapts the network it represents, and then spits out a new file.
The input/output files are EPANET files that are white-space separated with optional semi-colons at the end of each line.
The sections have keyword headers ([PIPES]), but some of these can be absent.
The work flow is demonstrated by the files under app/lib. The example modifies all junctions. Ideally it would skip junctions (not create a tank) if they start with a user selectable string (e.g. SKIP or S_). In a perfect world, another string (e.g., ROOF) would create a tank at a different height than the default height.

The code is only physically correct if the .inp file starts with hydraulic units of LPS. Additionally, it assumed Hazel-Williams is used for friction factor, but it's an easy tweak to make it work for Darcy-Weissbach also.
Use WNTR python package to parse the .inp files
