In -general, all access functions on tables are named `toml_*_in(...)`. - -In the normal case, you know the key and its content type, and retrievals can be done -using one of these functions: - -```c -toml_string_in(tab, key); -toml_bool_in(tab, key); -toml_int_in(tab, key); -toml_double_in(tab, key); -toml_timestamp_in(tab, key); -toml_table_in(tab, key); -toml_array_in(tab, key); -``` - -You can also interrogate the keys in a table using an integer index: - -```c -toml_table_t* tab = toml_parse_file(...); -for (int i = 0; ; i++) { - const char* key = toml_key_in(tab, i); - if (!key) break; - printf("key %d: %s\n", i, key); -} -``` - -### Accessing Array Content - -TOML arrays can be deref-ed using integer indices. In general, all access methods on arrays are named `toml_*_at()`. - -To obtain the size of an array: - -```c -int size = toml_array_nelem(arr); -``` - -To obtain the content of an array, use a valid index and call one of these functions: - -```c -toml_string_at(arr, idx); -toml_bool_at(arr, idx); -toml_int_at(arr, idx); -toml_double_at(arr, idx); -toml_timestamp_at(arr, idx); -toml_table_at(arr, idx); -toml_array_at(arr, idx); -``` - -### toml_datum_t - -Some `toml_*_at` and `toml_*_in` functions return a toml_datum_t -structure. The `ok` flag in the structure indicates if the function -call was successful. If so, you may proceed to read the value -corresponding to the type of the content. - -For example: - -```c -toml_datum_t host = toml_string_in(tab, "host"); -if (host.ok) { - printf("host: %s\n", host.u.s); - free(host.u.s); /* FREE applies to string and timestamp types only */ -} -``` - -**IMPORTANT: if the accessed value is a string or a timestamp, you must call `free(datum.u.s)` or `free(datum.u.ts)` respectively after usage.** - -## Building and installing - -A normal *make* suffices. You can also simply include the -`toml.c` and `toml.h` files in your project. - -Invoking `make install` will install the header and library files into -/usr/local/{include,lib}. - -Alternatively, specify `make install prefix=/a/file/path` to install into -/a/file/path/{include,lib}. - -## Testing - -To test against the standard test set provided by BurntSushi/toml-test: - -```sh -% make -% cd test1 -% bash build.sh # do this once -% bash run.sh # this will run the test suite -``` - -To test against the standard test set provided by iarna/toml: - -```sh -% make -% cd test2 -% bash build.sh # do this once -% bash run.sh # this will run the test suite -``` diff --git a/libraries/tomlc99/include/toml.h b/libraries/tomlc99/include/toml.h deleted file mode 100644 index b91ef890..00000000 --- a/libraries/tomlc99/include/toml.h +++ /dev/null @@ -1,175 +0,0 @@ -/* - MIT License - - Copyright (c) 2017 - 2019 CK Tan - https://github.com/cktan/tomlc99 - - Permission is hereby granted, free of charge, to any person obtaining a copy - of this software and associated documentation files (the "Software"), to deal - in the Software without restriction, including without limitation the rights - to use, copy, modify, merge, publish, distribute, sublicense, and/or sell - copies of the Software, and to permit persons to whom the Software is - furnished to do so, subject to the following conditions: - - The above copyright notice and this permission notice shall be included in all - copies or substantial portions of the Software. - - THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR - IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, - FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
