# Project management
-Please read documents in the ./lector directory for information
-about managing this project and using the tools, if any.
+As you are reading this you might be a GQL_to_Cypter-ologist. Please read
+documents in the ./ologist directory for project information, and the
+documents in the developer/ologist directory for documents on building
+the project.
-For developers, get started by typing:
+The project top level is for project management and imported tools. Developers
+do development work in the `developer` directory.
+
+For developers, from the top of the project get started by typing:
```
-> . developer_init
+> . executor/env_dev
``
-That is similar to the `activate` of Python.
+This will setup the environment and `cd` to the developer directory. (`env_dev`
+is analogous to the Python virtual environment `activate`.)
# About
-This is a transpiler from GQL to Cypher.
-
-The `syntax_recognizer` accepts a GQL query and then outputs a
-the syntax found as an XML file.
-
-# State of development
+This is a project to develope a transpiler from GQL to Cypher.
-Working on the `syntax_recognizer`.
-<!-- LocalWords: subdirectories transpiles Cypher transpiler

ANTLR grammar came from:
Note the antlr gammar on this site, many grammars listed.
https://github.com/antlr/grammars-v4
+ It came as four files:
+ ANTLRv4Lexer.g4
+ ANTLRv4Parser.g4
+ LexBasic.g4
+ LexerAdaptor.java

a pretty good job of that already.)

formal git project directory creation
Preparation, studies, and discussion occur before this time.
+2024-09-05
+
+ Diligence to the project was spotty in August.
+
+ Build environment appears to be stable. A toy grammar syntax parse, and echo,
+ and syntax 'diagramming' is working. Here 'diagramming' is a pretty print
+ annotation of the syntax parts.
+
+ GQL turns out to have a great deal in common with Cypher. So, might start by
+ using the Cypher movie database for testing. The ISO standard document should
+ clarify the differences.
+
+ The AI could not deal with the GQL grammar due to its size, so would not
+ generate a print visitor. I am working on abstracting the grammar to reduce
+ the number of rules.
+ In said abstraction, all terminal symbols will be under single token
+ `terminal`. Currently these are then categorized, then differentiated. The
+ categories were created manually. I wonder if categories are necessary, but
+ they can't hurt, and as they are done I will keep them.
