Image of rake → ruby version of make, ant
What is make in the first place ??
If you write the contents of Rakefile in ruby language </ strong>, Rakefile will work.
――The following program makes it possible to put the program on GitHub with one operation.
desc 'git push'
task :push do
#You can leave a comment with p
#I'm leaving comments for easy understanding
p comm = "git add -A"
#You can use external commands with system(However, the operation is slow)
system comm
p comm = "git commit -m \'hoge\'"
system comm
p comm = "git pull origin main"
system comm
p comm = "git push origin main"
system comm
exit
end
command_line
You can easily put the program on GitHub with the above program, but slow </ strong> because you are using an external command using system call.
So we use built-in functions.
However, the problem is that the return value from system is not the output, but whether the command was successful.
So, use command \ _line </ strong> to retrieve standard output (stdout) etc.
--How to install command \ _line
```bash
gem install command_line
```
org to_html, to_platex
The emacs org-mode is a command to output to ** html ** </ font> or ** latex ** </ font> Is prepared (too convenient ...)
--Execution command
c-c c-e ho # export as [h]tml, [o]ut
c-c c-e ll # export [l]atex, [l]atex
It's super convenient because you can easily convert the format written in org-mode to html or latex !!
However, it is hard to see in the output by default, so it is easier to understand if you set it positive.
