|
|
|
+
|
|
|
+ This library is the next generation of the [NoBuild](https://github.com/tsoding/nobuild) idea.
|
|
|
+
|
|
|
+ # Quick Example
|
|
|
+
|
|
|
+ ```c
|
|
|
+ // nob.c
|
|
|
+ #define NOB_IMPLEMENTATION
|
|
|
+ #include "nob.h"
|
|
|
+
|
|
|
+ int main(int argc, char **argv)
|
|
|
+ {
|
|
|
+ NOB_GO_REBUILD_URSELF(argc, argv);
|
|
|
+ Nob_Cmd cmd = {0};
|
|
|
+ nob_cmd_append(&cmd, "cc", "-Wall", "-Wextra", "-o", "main", "main.c");
|
|
|
+ if (!nob_cmd_run_sync(cmd)) return 1;
|
|
|
+ return 0;
|
|
|
+ }
|
|
|
+ ```
|
|
|
+
|
|
|
+ ```console
|
|
|
+ $ cc -o nob nob.c
|
|
|
+ $ ./nob
|
|
|
+ ```
|
|
|
+
|
|
|
+ The `nob` automatically rebuilds itself if `nob.c` is modified thanks to
|
|
|
+ the `NOB_GO_REBUILD_URSELF` macro (don't forget to check out how it works below)
|
|
|
+
|
|
|
+ # The Zoo of `nob_cmd_run_*` Functions
|
|
|
+
|
|
|
+ `Nob_Cmd` is just a dynamic array of strings which represents a command and its arguments.
|
|
|
+ First you append the arguments
|
|
|
+
|
|
|
+ ```c
|
|
|
+ Nob_Cmd cmd = {0};
|
|
|
+ nob_cmd_append(&cmd, "cc", "-Wall", "-Wextra", "-o", "main", "main.c");
|
|
|
+ ```
|
|
|
+
|
|
|
+ Then you run it
|
|
|
+
|
|
|
+ ```c
|
|
|
+ if (!nob_cmd_run_sync(cmd)) return 1;
|
|
|
+ ```
|
|
|
+
|
|
|
+ `*_sync` at the end indicates that the function blocks until the command finishes executing
|
|
|
+ and returns `true` on success and `false` on failure. You can run the command asynchronously
|
|
|
+ but you have to explitictly wait for it afterwards:
|
|
|
+
|
|
|
+ ```c
|
|
|
+ Nob_Proc p = nob_cmd_run_async(cmd);
|
|
|
+ if (p == NOB_INVALID_PROC) return 1;
|
|
|
+ if (!nob_proc_wait(p)) return 1;
|
|
|
+ ```
|
|
|
+
|
|
|
+ One of the problems with running commands like that is that `Nob_Cmd` still contains the arguments
|
|
|
+ from the previously run command. If you want to reuse the same `Nob_Cmd` you have to not forget to reset
|
|
|
+ it
|
|
|
+
|
|
|
+ ```c
|
|
|
+ Nob_Cmd cmd = {0};
|
|
|
+
|
|
|
+ nob_cmd_append(&cmd, "cc", "-Wall", "-Wextra", "-o", "main", "main.c");
|
|
|
+ if (!nob_cmd_run_sync(cmd)) return 1;
|
|
|
+ cmd.count = 0;
|
|
|
+
|
|
|
+ nob_cmd_append(&cmd, "./main", "foo", "bar", "baz");
|
|
|
+ if (!nob_cmd_run_sync(cmd)) return 1;
|
|
|
+ cmd.count = 0;
|
|
|
+ ```
|
|
|
+
|
|
|
+ Which is a bit error prone. To make it a bit easier we have `nob_cmd_run_sync_and_reset()` which
|
|
|
+ accepts `Nob_Cmd` by reference and resets it for you:
|
|
|
+
|
|
|
+ ```c
|
|
|
+ Nob_Cmd cmd = {0};
|
|
|
+
|
|
|
+ nob_cmd_append(&cmd, "cc", "-Wall", "-Wextra", "-o", "main", "main.c");
|
|
|
+ if (!nob_cmd_run_sync_and_reset(&cmd)) return 1;
|
|
|
+
|
|
|
+ nob_cmd_append(&cmd, "./main", "foo", "bar", "baz");
|
|
|
+ if (!nob_cmd_run_sync_and_reset(&cmd)) return 1;
|
|
|
+ ```
|
|
|
+
|
|
|
+ There is of course also `nob_cmd_run_async_and_reset()` to maintain the pattern.
|
|
|
+
|
|
|
+ The stdin, stdout and stderr of any command can be redirected by using `Nob_Cmd_Redirect` structure
|
|
|
+ along with `nob_cmd_run_sync_redirect()` or `nob_cmd_run_async_redirect()`
|
|
|
+
|
|
|
+ ```c
|
|
|
+ // Opening all the necessary files
|
|
|
+ Nob_Fd fdin = nob_fd_open_for_read("input.txt");
|
|
|
+ if (fdin == NOB_INVALID_FD) return 1;
|
|
|
+ Nob_Fd fdout = nob_fd_open_for_write("output.txt");
|
|
|
+ if (fdout == NOB_INVALID_FD) return 1;
|
|
|
+ Nob_Fd fderr = nob_fd_open_for_write("error.txt");
|
|
|
+ if (fderr == NOB_INVALID_FD) return 1;
|
|
|
+
|
|
|
+ // Preparing the command
|
|
|
+ Nob_Cmd cmd = {0};
|
|
|
+ nob_cmd_append(&cmd, "./main", "foo", "bar", "baz");
|
|
|
+
|
|
|
+ // Running the command synchronously redirecting the standard streams
|
|
|
+ bool ok = nob_cmd_run_sync_redirect(cmd, (Nob_Cmd_Redirect) {
|
|
|
+ .fdin = fdin,
|
|
|
+ .fdout = fdout,
|
|
|
+ .fderr = fderr,
|
|
|
+ });
|
|
|
+ if (!ok) return 1;
|
|
|
+
|
|
|
+ // Closing all the files
|
|
|
+ nob_fd_close(fdin);
|
|
|
+ nob_fd_close(fdout);
|
|
|
+ nob_fd_close(fderr);
|
|
|
+
|
|
|
+ // Reseting the command
|
|
|
+ cmd.count = 0;
|
|
|
+ ```
|
|
|
+
|
|
|
+ And of course if you find closing the files and reseting the command annoying we have
|
|
|
+ `nob_cmd_run_sync_redirect_and_reset()` and `nob_cmd_run_async_redirect_and_reset()`
|
|
|
+ which do all of that for you automatically.
|
|
|
+
|
|
|
+ All the Zoo of `nob_cmd_run_*` functions follows the same pattern: sync/async,
|
|
|
+ redirect/no redirect, and_reset/no and_reset. They always come in that order.
|
|
|
+
|
|
|
+ # Stripping off `nob_` Prefixes
|
|
|
+
|
|
|
+ Since Pure C does not have any namespaces we prefix each name of the API with the `nob_` to avoid any
|
|
|
+ potential conflicts with any other names in your code. But sometimes it is very annoying and makes
|
|
|
+ the code noisy. If you know that none of the names from nob.h conflict with anything in your code
|
|
|
+ you can enable NOB_STRIP_PREFIX macro and just drop all the prefixes:
|
|
|
+
|
|
|
+ ```c
|
|
|
+ // nob.c
|
|
|
+ #define NOB_IMPLEMENTATION
|
|
|
+ #define NOB_STRIP_PREFIX
|
|
|
+ #include "nob.h"
|
|
|
+
|
|
|
+ int main(int argc, char **argv)
|
|
|
+ {
|
|
|
+ NOB_GO_REBUILD_URSELF(argc, argv);
|
|
|
+ Cmd cmd = {0};
|
|
|
+ cmd_append(&cmd, "cc", "-Wall", "-Wextra", "-o", "main", "main.c");
|
|
|
+ if (!cmd_run_sync(cmd)) return 1;
|
|
|
+ return 0;
|
|
|
+ }
|
|
|
+ ```
|
|
|
+
|
|
|
+ Not all the names have strippable prefixes. All the redefinable names like `NOB_GO_REBUILD_URSELF`
|
|
|
+ for instance will retain their prefix even if NOB_STRIP_PREFIX is enabled. Notable exception is the
|
|
|
+ nob_log() function. Stripping away the prefix results in log() which was historically always referring
|
|
|
+ to the natural logarithmic function that is already defined in math.h. So there is no reason to strip
|
|
|
+ off the prefix for nob_log(). Another exception is nob_rename() which collides with the widely known
|
|
|
+ POSIX function rename(2) if you strip the prefix off.
|
|
|
+
|
|
|
+ The prefixes are stripped off only on the level of preprocessor. The names of the functions in the
|
|
|
+ compiled object file will still retain the `nob_` prefix. Keep that in mind when you FFI with nob.h
|
|
|
+ from other languages (for whatever reason).
|
|
|
+
|
|
|
+ If only few specific names create conflicts for you, you can just #undef those names after the
|
|
|
+ `#include <nob.h>` since they are macros anyway.

|
|
|
+ Version Conventions:
|
|
|
+
|
|
|
+ We are following https://semver.org/ so the version has a format MAJOR.MINOR.PATCH:
|
|
|
+ - Modifying comments does not update the version.
|
|
|
+ - PATCH is incremented in case of a bug fix or refactoring without touching the API.
|
|
|
+ - MINOR is incremented when new functions and/or types are added in a way that does
|
|
|
+ not break any existing user code. We want to do this in the majority of the situation.
|
|
|
+ If we want to delete a certain function or type in favor of another one we should
|
|
|
+ just add the new function/type and deprecate the old one in a backward compatible way
|
|
|
+ and let them co-exist for a while.
|
|
|
+ - MAJOR update should be just a periodic cleanup of the deprecated functions and types
|
|
|
+ without really modifying any existing functionality.
|
|
|
+
|
|
|
+ Naming Conventions:
|
|
|
+
|
|
|
+ - All the user facing names should be prefixed with `nob_` or `NOB_` depending on the case.
|
|
|
+ - The prefixes of non-redefinable names should be strippable with NOB_STRIP_PREFIX (unless
|
|
|
+ explicitly stated otherwise like in case of nob_log).
|
|
|
+ - Internal functions should be prefixed with `nob__` (double underscore).
