home what is this about?

This is a demonstration of how a very small ruleset can be used to generate makefiles from source text in a subset of the mediawiki text format. The advantage of doing this is that the same format can be used to generate HTML pages. Also, for anyone who prefers using text editor settings that replace TAB by spaces, the makefile format is awkward, and the make system itself somewhat harsh and unhelpful.

home sources

home configuration

Local configuration - paths to the D compiler etc - is held in an include file.

 include ../config/config.mak

The following should possibly be in the config file:

 LM     = $(LMPREFIX)/bin/lm
 LMN2M  = lmn2m
 LMN2D  = lmn2d
 LMN2C  = lmn2c
 LMN2DD = lmn2D
 LMN2CC = lmn2C
 WIKI2HTML = ./makesite.lm

This is a list of files to be maintained when this Makefile is being used to maintain a website:

 HTMLFILES=  mediawiki.html
 HTMLFILES+= sitehtml.html
 HTMLFILES+= wiki2make.html
 HTMLFILES+= testmakefile.html

home targets 

 all: wiki2make.lm testmakefile.mak makesite.lm $(HTMLFILES)

 clean:
         rm -f *.html
         rm -f *.lm *.out *.lmr *.o *~  
         rm -f *.tcc *.tCc *.gcc *.gCc *.gdc *.gDc 

 makesite.lm: mediawiki.lmn sitehtml.lmn
         $(LMN2M) $+ -o $@ -s $(LM); 
         chmod +x $@
