<h2 id='section_lexer_library'>§2 Lexer Library</h2><h3>§2.1 Lexer Intro</h3><div>The 4cpp lexer system provides a polished, fast, flexible system that takes in C/C++ and outputs a tokenization of the text data. There are two API levels. One level is setup to let you easily get a tokenization of the file. This level manages memory for you with malloc to make it as fast as possible to start getting your tokens. The second level enables deep integration by allowing control over allocation, data chunking, and output rate control.<br><br>To use the quick setup API you simply include 4cpp_lexer.h and read the documentation at <a href='#cpp_lex_file_doc'>cpp_lex_file</a>.<br><br>To use the the fancier API include 4cpp_lexer.h and read the documentation at <a href='#cpp_lex_step_doc'>cpp_lex_step</a>. If you want to be absolutely sure you are not including malloc into your program you can define FCPP_FORBID_MALLOC before the include and the "step" API will continue to work.<br><br>There are a few more features in 4cpp that are not documented yet. You are free to try to use these, but I am not totally sure they are ready yet, and when they are they will be documented.</div><h3>§2.2 Lexer Function List</h3><ul><li><a href='#cpp_get_token_doc'>cpp_get_token</a></li><li><a href='#cpp_lex_step_doc'>cpp_lex_step</a></li><li><a href='#cpp_lex_data_init_doc'>cpp_lex_data_init</a></li><li><a href='#cpp_lex_data_temp_size_doc'>cpp_lex_data_temp_size</a></li><li><a href='#cpp_lex_data_temp_read_doc'>cpp_lex_data_temp_read</a></li><li><a href='#cpp_lex_data_new_temp_DEP_doc'>cpp_lex_data_new_temp_DEP</a></li><li><a href='#cpp_get_relex_range_doc'>cpp_get_relex_range</a></li><li><a href='#cpp_relex_init_doc'>cpp_relex_init</a></li><li><a href='#cpp_relex_start_position_doc'>cpp_relex_start_position</a></li><li><a href='#cpp_relex_declare_first_chunk_position_doc'>cpp_relex_declare_first_chunk_position</a></li><li><a href='#cpp_relex_is_start_chunk_doc'>cpp_relex_is_start_chunk</a></li><li><a href='#cpp_relex_step_doc'>cpp_relex_step</a></li><li><a href='#cpp_relex_get_new_count_doc'>cpp_relex_get_new_count</a></li><li><a href='#cpp_relex_complete_doc'>cpp_relex_complete</a></li><li><a href='#cpp_relex_abort_doc'>cpp_relex_abort</a></li><li><a href='#cpp_make_token_array_doc'>cpp_make_token_array</a></li><li><a href='#cpp_free_token_array_doc'>cpp_free_token_array</a></li><li><a href='#cpp_resize_token_array_doc'>cpp_resize_token_array</a></li><li><a href='#cpp_lex_file_doc'>cpp_lex_file</a></li></ul><h3>§2.3 Lexer Types List</h3><ul><li><a href='#Cpp_Token_Type_doc'>Cpp_Token_Type</a></li><li><a href='#Cpp_Token_doc'>Cpp_Token</a></li><li><a href='#Cpp_Token_Flag_doc'>Cpp_Token_Flag</a></li><li><a href='#Cpp_Token_Array_doc'>Cpp_Token_Array</a></li><li><a href='#Cpp_Get_Token_Result_doc'>Cpp_Get_Token_Result</a></li><li><a href='#Cpp_Relex_Range_doc'>Cpp_Relex_Range</a></li><li><a href='#Cpp_Lex_Data_doc'>Cpp_Lex_Data</a></li><li><a href='#Cpp_Lex_Result_doc'>Cpp_Lex_Result</a></li><li><a href='#Cpp_Relex_Data_doc'>Cpp_Relex_Data</a></li></ul><h3>§2.4 Lexer Function Descriptions</h3><div id='cpp_get_token_doc' style='margin-bottom: 1cm;'><h4>§2.4.1: cpp_get_token</h4><div style='font-family: "Courier New", Courier, monospace; text-align: left; margin-top: 3mm; margin-bottom: 3mm; font-size: .95em; background: #DFDFDF; padding: 0.25em;'>Cpp_Get_Token_Result cpp_get_token(<div style='margin-left: 4mm;'>Cpp_Token_Array array,<br>int32_t pos<br></div>)</div><div style='margin-top: 3mm; margin-bottom: 3mm; color: #309030;'><b><i>Parameters</i></b></div><div><div style='font-weight: 600;'>array</div><div style='margin-bottom: 6mm;'><div style='margin-left: 5mm; margin-right: 5mm;'>The array of tokens from which to get a token.</div></div></div><div><div style='font-weight: 600;'>pos</div><div style='margin-bottom: 6mm;'><div style='margin-left: 5mm; margin-right: 5mm;'>The position, measured in bytes, to get the token for.</div></div></div><div style='margin-top: 3mm; margin-bottom: 3mm; color: #309030;'><b><i>Return</i></b></div><div style='margin-left: 5mm; margin-right: 5mm;'>A Cpp_Get_Token_Result struct is returned containing the index

It is quite general so it can be used in
|
|
a lot of different ways. I will explain the general rules first, and then give some examples of common
|
|
ways it might be used.<br><br>
|
|
First a lexing state, Cpp_Lex_Data, must be initialized. The file to lex must be read into N contiguous chunks
|
|
of memory. An output Cpp_Token_Array must be allocated and initialized with the appropriate count and max_count
|
|
values. Then each chunk of the file must be passed to cpp_lex_step in order using the same lexing state for each call.
|
|
Every time a call to cpp_lex_step returns LexResult_NeedChunk, the next call to cpp_lex_step should use the
|
|
next chunk. If the return is some other value, the lexer hasn't finished with the current chunk and it sopped for some
|
|
other reason, so the same chunk should be used again in the next call.<br><br>
|
|
If the file chunks contain a null terminator the lexer will return LexResult_Finished when it finds this character.
|
|
At this point calling the lexer again with the same state will result in an error. If you do not have a null
|
|
terminated chunk to end the file, you may instead pass the exact size in bytes of the entire file to the full_size
|
|
parameter and it will automatically handle the termination of the lexing state when it has read that many bytes.
|
|
If a full_size is specified and the system terminates for having seen that many bytes, it will return
|
|
LexResult_Finished. If a full_size is specified and a null character is read before the total number of bytes have
|
|
been read the system will still terminate as usual and return LexResult_Finished.<br><br>
|
|
If the system has filled the entire output array it will return LexResult_NeedTokenMemory. When this happens if you
|
|
want to continue lexing the file you can grow the token array, or switch to a new output array and then call
|
|
cpp_lex_step again with the chunk that was being lexed and the new output. You can also specify a max_tokens_out
|
|
which is limits how many new tokens will be added to the token array. Even if token_array_out still had more space
|
|
to hold tokens, if the max_tokens_out limit is hit, the lexer will stop and return LexResult_HitTokenLimit. If this
|
|
happens there is still space left in the token array, so you can resume simply by calling cpp_lex_step again with
|
|
the same chunk and the same output array. Also note that, unlike the chunks which must only be replaced when the
|
|
system says it needs a chunk. You may switch to or modify the output array in between calls as much as you like.<br><br>
|
|
The most basic use of this system is to get it all done in one big chunk and try to allocate a nearly "infinite" output
|
|
array so that it will not run out of memory. This way you can get the entire job done in one call and then just assert
|
|
to make sure it returns LexResult_Finished to you:<br><br>

The system needs a temporary buffer that is as long as the longest token. 4096 is usually

|
enough but the buffer is not checked, so to be 100% bullet proof it has to be the same length

as the file being lexed.<br><br></div></div><hr><div id='cpp_lex_data_temp_size_doc' style='margin-bottom: 1cm;'><h4>§2.4.4: cpp_lex_data_temp_size</h4><div style='font-family: "Courier New", Courier, monospace; text-align: left; margin-top: 3mm; margin-bottom: 3mm; font-size: .95em; background: #DFDFDF; padding: 0.25em;'>int32_t cpp_lex_data_temp_size(<div style='margin-left: 4mm;'>Cpp_Lex_Data *lex_data<br></div>)</div><div style='margin-top: 3mm; margin-bottom: 3mm; color: #309030;'><b><i>Parameters</i></b></div><div><div style='font-weight: 600;'>lex_data</div><div style='margin-bottom: 6mm;'><div style='margin-left: 5mm; margin-right: 5mm;'>The lex state from which to get the temporary buffer size.</div></div></div><div style='margin-top: 3mm; margin-bottom: 3mm; color: #309030;'><b><i>Description</i></b></div><div style='margin-left: 5mm; margin-right: 5mm;'>This call gets the current size of the temporary buffer in the lexer state so

|
|
|
|
To get an appropriate capacity for relex_array, you can get the range of tokens that the relex

operation is likely to traverse by looking at the result from cpp_get_relex_range.</div></div></div><div style='margin-top: 3mm; margin-bottom: 3mm; color: #309030;'><b><i>Description</i></b></div><div style='margin-left: 5mm; margin-right: 5mm;'>When a file has already been lexed, and then it is edited in a small local way,
|
|
rather than lexing the new file all over again, cpp_relex_step can try to find just
|
|
the range of tokens that need to be updated and fix them in.<br><br>
|
|
First the lex state must be initialized (cpp_relex_init). Then one or more calls to
|
|
cpp_relex_step will start editing the array and filling out the relex_array. The return
|
|
value of cpp_relex_step indicates whether the relex was successful or was interrupted
|
|
and if it was interrupted, what the system needs to resume.<br><br>
|
|
LexResult_Finished indicates that the relex engine finished successfully.<br><br>
|
|
LexResult_NeedChunk indicates that the system needs the next chunk of the file.<br><br>
|
|
LexResult_NeedTokenMemory indicates that the relex_array has reached capacity, and that
|
|
it needs to be extended if it is going to continue. Sometimes in this case it is better
|
|
to stop and just lex the entire file normally, because there are a few cases where a small
|
|
local change effects a long range of the lexers output.<br><br>
|
|
The relex operation can be closed in one of two ways. If the LexResult_Finished
|
|
value has been returned by this call, then to complete the edits to the array make
|
|
sure the original array has enough capacity to store the final result by calling
|
|
cpp_relex_get_new_count. Then the operation can be finished successfully by calling
|
|
cpp_relex_complete.<br><br>
|
|
Whether or not the relex process finished with LexResult_Finished the process can be
|
|
finished by calling cpp_relex_abort, which puts the array back into it's original state.
|
|
No close is necessary if getting the original array state back is not necessary.<br><br></div><div style='margin-top: 3mm; margin-bottom: 3mm; color: #309030;'><b><i>See Also</i></b></div><div style='margin-left: 5mm; margin-right: 5mm;'><a href='#cpp_relex_init_doc'>cpp_relex_init</a></div><div style='margin-left: 5mm; margin-right: 5mm;'><a href='#cpp_get_relex_range_doc'>cpp_get_relex_range</a></div><div style='margin-left: 5mm; margin-right: 5mm;'><a href='#Cpp_Lex_Result_doc'>Cpp_Lex_Result</a></div><div style='margin-left: 5mm; margin-right: 5mm;'><a href='#cpp_relex_get_new_count_doc'>cpp_relex_get_new_count</a></div><div style='margin-left: 5mm; margin-right: 5mm;'><a href='#cpp_relex_complete_doc'>cpp_relex_complete</a></div><div style='margin-left: 5mm; margin-right: 5mm;'><a href='#cpp_relex_abort_doc'>cpp_relex_abort</a></div></div><hr><div id='cpp_relex_get_new_count_doc' style='margin-bottom: 1cm;'><h4>§2.4.13: cpp_relex_get_new_count</h4><div style='font-family: "Courier New", Courier, monospace; text-align: left; margin-top: 3mm; margin-bottom: 3mm; font-size: .95em; background: #DFDFDF; padding: 0.25em;'>int32_t cpp_relex_get_new_count(<div style='margin-left: 4mm;'>Cpp_Relex_Data *S_ptr,<br>int32_t current_count,<br>Cpp_Token_Array *relex_array<br></div>)</div><div style='margin-top: 3mm; margin-bottom: 3mm; color: #309030;'><b><i>Parameters</i></b></div><div><div style='font-weight: 600;'>S_ptr</div><div style='margin-bottom: 6mm;'><div style='margin-left: 5mm; margin-right: 5mm;'>A pointer to a state that has gone through cpp_relex_step with a LexResult_Finished return.</div></div></div><div><div style='font-weight: 600;'>current_count</div><div style='margin-bottom: 6mm;'><div style='margin-left: 5mm; margin-right: 5mm;'>The count of tokens in the original array before the edit.</div></div></div><div><div style='font-weight: 600;'>relex_array</div><div style='margin-bottom: 6mm;'><div style='margin-left: 5mm; margin-right: 5mm;'>The relex_array that was used in the cpp_relex_step call/calls.</div></div></div><div style='margin-top: 3mm; margin-bottom: 3mm; color: #309030;'><b><i>Description</i></b></div><div style='margin-left: 5mm; margin-right: 5mm;'>After getting a LexResult_Finished from cpp_relex_step, this call can be used to get
