#define | CTPL_LEXER_ERROR |
CtplToken * | ctpl_lexer_lex () |
CtplToken * | ctpl_lexer_lex_string () |
CtplToken * | ctpl_lexer_lex_path () |
Syntax analyser creating a token tree from an input data in the CTPL language.
To analyse some data, use ctpl_lexer_lex()
, ctpl_lexer_lex_string()
or
ctpl_lexer_lex_path()
; to destroy the created token tree, use
ctpl_token_free()
.

CtplToken *tree; GError *error = NULL; tree = ctpl_lexer_lex (input, &error); if (tree == NULL) { fprintf (stderr, "Failed to analyse input data: %s\n", error->message); g_clear_error (&error); } else { /* do what you want with the tree here */ ctpl_token_free (tree); } |
CtplToken * ctpl_lexer_lex (CtplInputStream *stream
,GError **error
);
Analyses some given data and tries to create a tree of tokens representing it.
stream |
A CtplInputStream holding the data to analyse |
|
error |
A GError return location for error reporting, or |
A new CtplToken tree holding all read tokens or NULL
on error.
The new tree should be freed with ctpl_token_free()
when no longer
needed.
CtplToken * ctpl_lexer_lex_string (const gchar *template
,GError **error
);
Convenient function to lex a template from a string.
See ctpl_lexer_lex()
.
template |
A string containing the template data |
|
error |
Return location for errors, or |
CtplToken * ctpl_lexer_lex_path (const gchar *path
,GError **error
);
Convenient function to lex a template from a file.
See ctpl_lexer_lex()
.
Errors can come from the G_IO_ERROR
domain if the file loading fails, or
from the CTPL_LEXER_ERROR
domain if the lexing fails.
path |
The path of the file from which read the template, in the GLib's filename encoding |
|
error |
Return location for errors, or |
