apps/interpreters README file ============================= This apps/ directory is set aside to hold interpreters that may be incorporated into NuttX. ficl ---- This is DIY port of Ficl (the "Forth Inspired Command Language"). See http://ficl.sourceforge.net/. It is a "DIY" port because the Ficl source is not in that directory, only an environment and instructions that will let you build Ficl under NuttX. The rest is up to you. pcode ----- At present, only the NuttX Pascal add-on is supported. This NuttX add-on must be downloaded separately (or is available in an GIT snapshot in the misc/pascal directory). This Pascal add-on must be installed into the NuttX apps/ directory. After unpacking the Pascal add-on package, an installation script and README.txt instructions can be found at pascal/nuttx. INSTALL.sh -- The script that performs the operation. Usage: ./INSTALL.sh [-16|-32] If you are using this standard NuttX apps/ package, the correct location for the is apps/interpreters. That is where the examples and build logic will expect to find the pcode sub-directory. Example: ./INSTALL.sh -16 $PWD/../../../apps/interpreters After installation, the NuttX apps/interpresters directory will contain the following files pcode |-- Makefile |-- include | `-- Common header files |-- libboff | `-- Pascal object format (POFF) library `--insn |-- include | `-- model-specific header files `-- prun `-- model-specific source files pashello There is a simple Pascal example at apps/examples/pashello. This is the standard "Hello, World!" example written in Pascal and interpreted from Pascal P-Code at runtime. To use this example, place the following in your appconfig file" # Path to example in apps/examples containing the passhello_main entry point CONFIGURED_APPS += examples/pashello # Path to the Pascal p-code runtime interpreter module CONFIGURED_APPS += interpreters/pcode
