I'm using Eclipse CDT for a C project with custom makefiles, and I want to use the inactive code highlighting as proposed in the answers to question 739230. The automatic discovery of active/defined symbols does not work for my makefiles. Instead I have created a text file for each build target listing the active symbols.
So my questions are:
- How do I load these settings into a the project without going through the GUI (folder properties -> Paths and Symbols -> Symbols)?
- And how do I choose which configuration/build target the symbols are added to?
Directly editing the the .cproject file and adding lines like this works:
<listOptionValue builtIn="false" value="HIRES_OUTPUT"/>
But only if I go through the GUI to create the first key for each build target. I would prefer to create the build target and import the symbols in one operation.
Writing an Eclipse plugin from scratch seems like overkill for this task.
Any ideas for a smarter way to do this?
The Import/Export Wizard can handle Symbol Definitions. Use File->Import and choose C/C++ Project Settings.
The XML format needed by the Import Wizard can be created from the text file of active symbols with a small throw-away script.
I used the following python script:
# # Tool to import a list of defined symbols into Eclipse IDE for code highlighting. # # Takes a _cdef.txt file (generated during library build) and converts to an XML file # suitable for import into Eclipse # Use stdin and stdout for input and output. import sys import string header = [ '<?xml version="1.0" encoding="UTF-8"?>', '<cdtprojectproperties>' , '<section name="org.eclipse.cdt.internal.ui.wizards.settingswizards.Macros">', '<language name="holder for library settings">', '', '</language>', '<language name="GNU C++">', '', '</language>', '<language name="GNU C">', '' ] sys.stdout.write (string.join(header, '\n')) text=sys.stdin.readlines() tokens = string.split(string.strip(text),',') for curtok in tokens: lines = ['<macro>', '<name>' + string.strip(curtok) + '</name><value></value>', '</macro>', ''] sys.stdout.write(string.join(lines, '\n')) footer = [ '', '</language>', '<language name="Assembly">', '', '</language>', '</section>', '</cdtprojectproperties>', ''] sys.stdout.write (string.join(footer, '\n'))
The input to the script is a text file with the comma-separated active symbols, all on the first line.
