# make
Program 3 for cs537
* Developers: Dillon O'Leary, Ezra Boley 

## Program Structure
There are three phases that the program goes through. 

First it reads each line of the file using the functions in parse_text.c and compiles a list of targets, commands, and dependencies. 

Then it uses a hashmap and the functions in assess_specs.c to create a graph of dependencies and that is where it decides which commands need to be run and which can be discarded.

Lastly the compiled list of instructions is passed into spawn.c which is responsible for creating each process and making sure each executes successfully.

make.c contains the main control loop for the program.

## Running
537make accepts a specific target to build as a command line arguement as well as the -f option followed by a specific file name.

## Release Notes:
The only warning coming from clang is for the file pointer, there is a note about it at the location of the warning, the end of parse_text.c

## Changes for 3-1: format <file-name>:<line-number-of-change>
    parse_text.c:16 || Function renamed to be more consistent with the overall naming scheme, and args were changed
    parse_text.c:18 || File is opened in this function instead to better limit the scope it is available
This change was also made because it makes the freeing of the FILE* easier, to avoid a memory leak.
    parse_text.c:28 || File close was added so that memory can be successfully freed
    parse_text.c:29 || The FILE * for the file read in is freed, this * this fixes the Clang warning *.
    parse_text.c:18 || The temp buffer for each line is initialized. Valgrind did not like that it contained garbage, 
and it was especially a problem at the check_colon function. By clearing it to "", the problem is solved.
