# XML output generator for Open Fortran Parser
2+
3+
This is an extension of Open Fortran Parser (OFP), which outputs abstract syntaxt tree (AST)
4+
in XML format - to a file or to 'System.out'.
5+
6+
7+
## dependencies
8+
9+
- Open Fortran Parser 0.8.4-1
10+
11+
https://github.com/mbdevpl/open-fortran-parser/releases/tag/v0.8.4-1
12+
13+
This is a patched version of OFP. Specifically, 'FortranParserActionPrint' class in OFP
14+
could not be properly subclassed due to access levels of members of that class, so for example
15+
writing my own printer would introduce a lot of code duplication. Patch resolves this,
16+
without affecting any functionality of the Parser.
17+
18+
The patch also resolves some issue when compiling with recent GCC versions.
19+
20+
- ANTRL 3.3 (dependency of Open Fortran Parser)
21+
22+
http://www.antlr3.org/download/
23+
24+
- Apache Commons CLI
25+
26+
https://commons.apache.org/proper/commons-cli/download_cli.cgi
27+
28+
29+
## how to run
30+
31+
32+
## AST specification
33+
34+
In progress.
35+
36+
Root node is '<ofp>', it has one subnode '<file>'.
