=== QUESTION ===
|
|
Please write a GNU Makefile, which uses the command `cmm print -f db/<fname> -a >out/gpu_plan.md` and `python convert.py out/gpu_plan.md` if source file is changing, to create `out/gpu_plan.html`.
|
|
==== ANSWER ====
|
|
Here's a GNU Makefile that performs the required operations:
|
|
|
|
```makefile
|
|
# Variables to define the source and output directories
|
|
SRC_DIR = db
|
|
OUT_DIR = out
|
|
|
|
# List of source files without extension
|
|
SOURCES = 0014 0022 0013 0001 0016 0017 0018 0023 0019 0002 0025
|
|
|
|
# Add directory and extension to the source filenames
|
|
SRC_FILES = $(SOURCES:%=$(SRC_DIR)/%.txt)
|
|
|
|
# Add directory and .md extension to the markdown filenames
|
|
MD_FILES = $(SOURCES:%=$(OUT_DIR)/%.md)
|
|
|
|
# Add .html extension for the HTML filenames
|
|
HTML_FILES = $(MD_FILES:.md=.html)
|
|
|
|
# Default target
|
|
all: Makefile convert.py $(HTML_FILES) $(OUT_DIR)/learning.html
|
|
|
|
Makefile: $(SRC_DIR)/0026.txt
|
|
cmm print -f $< -S | sed "s/ `printf ' /\t/g'`" >$@
|
|
|
|
convert.py: $(SRC_DIR)/0003.txt Makefile
|
|
cmm print -f $< -S >$@
|
|
|
|
# Rule to create a markdown file from a source file
|
|
$(OUT_DIR)/%.md: $(SRC_DIR)/%.txt
|
|
cmm print -f $< -a > $@
|
|
|
|
# Rule to create an HTML file from a markdown file
|
|
$(OUT_DIR)/%.html: $(OUT_DIR)/%.md convert.py
|
|
python convert.py $<
|
|
|
|
$(OUT_DIR)/learning.html: $(SRC_DIR)/0015.txt $(SRC_FILES) Makefile
|
|
cmm print -f $< -S | \
|
|
awk "/LINKS_LINE/ { \
|
|
split(\"$(SOURCES)\", sources, \" \"); \
|
|
for (i = 1; i <= length(sources); i++) { \
|
|
\"awk '/^# /{ sub(/^# /, \\\"\\\"); print \$0; }' db/\" sources[i] \".txt\" | getline NAME; \
|
|
print \" <li><a href=\\\"\" sources[i] \".html\\\">\" NAME \"</a></li>\"; \
|
|
} \
|
|
} 1" > $@
|
|
|
|
# Target to clean the output directory
|
|
clean:
|
|
rm -f $(OUT_DIR)/*
|
|
|
|
.PHONY: all clean
|
|
```
|
|
|
|
In this `Makefile`:
|
|
|
|
1. `SOURCES` is a list of all source files (without their file extensions). You can add or remove file names from this list as needed.
|
|
2. The `SRC_FILES`, `MD_FILES`, and `HTML_FILES` variables generate the full filenames with directory and extension based on the `SOURCES` list.
|
|
3. The `$(OUT_DIR)/%.md: $(SRC_DIR)/%.txt` and `$(OUT_DIR)/%.html: $(OUT_DIR)/%.md` rules use pattern-matching to create the appropriate `.md` or `.html` file for each source file.
|
|
4. The `all` target now depends on `$(HTML_FILES)`, which means it will generate an HTML file for each source file listed in `SOURCES`.
|
|
|
|
The `%.txt` and `%.md` are pattern matching rules that match any file with a `.txt` or `.md` extension respectively. `$<` refers to the first prerequisite (i.e., the source file), and `$@` refers to the target of the rule.
|
|
|
|
Generate the `Makefile` with this command: `cmm print -f db/0026.txt -S | sed $'s/ /\t/g' >Makefile`
|
|
|
|
To run this `Makefile`, you can still use `make` command in the terminal, and `make clean` to clean up the output directory.
