From e5fba602e59292c8c383a7a587897b5f7cbd5c78 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Cl=C3=A9ment=20Poulain?= Date: Tue, 15 Jun 2010 17:50:28 +0200 Subject: textconv: support for cat_file MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Make the textconv_object function public, and add --textconv option to cat-file to perform conversion on blob objects. Using --textconv implies that we are working on a blob. As files drivers need to be initialized, a new config is required in addition to git_default_config. Therefore git_cat_file_config() is introduced Signed-off-by: Clément Poulain Signed-off-by: Diane Gasselin Signed-off-by: Axel Bonnet Signed-off-by: Junio C Hamano --- builtin.h | 2 ++ builtin/blame.c | 8 ++++---- builtin/cat-file.c | 38 ++++++++++++++++++++++++++++++++++---- 3 files changed, 40 insertions(+), 8 deletions(-) diff --git a/builtin.h b/builtin.h index 5c887ef61b..5a1dba0069 100644 --- a/builtin.h +++ b/builtin.h @@ -36,6 +36,8 @@ void finish_copy_notes_for_rewrite(struct notes_rewrite_cfg *c); extern int check_pager_config(const char *cmd); +extern int textconv_object(const char *path, const unsigned char *sha1, char **buf, unsigned long *buf_size); + extern int cmd_add(int argc, const char **argv, const char *prefix); extern int cmd_annotate(int argc, const char **argv, const char *prefix); extern int cmd_apply(int argc, const char **argv, const char *prefix); diff --git a/builtin/blame.c b/builtin/blame.c index 7bbe7612a1..2e63648ea0 100644 --- a/builtin/blame.c +++ b/builtin/blame.c @@ -91,10 +91,10 @@ struct origin { * if the textconv driver exists. * Return 1 if the conversion succeeds, 0 otherwise. */ -static int textconv_object(const char *path, - const unsigned char *sha1, - char **buf, - unsigned long *buf_size) +int textconv_object(const char *path, + const unsigned char *sha1, + char **buf, + unsigned long *buf_size) { struct diff_filespec *df; struct userdiff_driver *textconv; diff --git a/builtin/cat-file.c b/builtin/cat-file.c index a933eaa043..cada5d2257 100644 --- a/builtin/cat-file.c +++ b/builtin/cat-file.c @@ -9,6 +9,8 @@ #include "tree.h" #include "builtin.h" #include "parse-options.h" +#include "diff.h" +#include "userdiff.h" #define BATCH 1 #define BATCH_CHECK 2 @@ -84,10 +86,11 @@ static int cat_one_file(int opt, const char *exp_type, const char *obj_name) { unsigned char sha1[20]; enum object_type type; - void *buf; + char *buf; unsigned long size; + struct object_context obj_context; - if (get_sha1(obj_name, sha1)) + if (get_sha1_with_context(obj_name, sha1, &obj_context)) die("Not a valid object name %s", obj_name); buf = NULL; @@ -132,6 +135,17 @@ static int cat_one_file(int opt, const char *exp_type, const char *obj_name) /* otherwise just spit out the data */ break; + + case 'c': + if (!obj_context.path[0]) + die("git cat-file --textconv %s: must be ", + obj_name); + + if (!textconv_object(obj_context.path, sha1, &buf, &size)) + die("git cat-file --textconv: unable to run textconv on %s", + obj_name); + break; + case 0: buf = read_object_with_reference(sha1, exp_type, &size, NULL); break; @@ -201,11 +215,25 @@ static int batch_objects(int print_contents) } static const char * const cat_file_usage[] = { - "git cat-file (-t|-s|-e|-p|) ", + "git cat-file (-t|-s|-e|-p||--textconv) ", "git cat-file (--batch|--batch-check) < ", NULL }; +static int git_cat_file_config(const char *var, const char *value, void *cb) +{ + switch (userdiff_config(var, value)) { + case 0: + break; + case -1: + return -1; + default: + return 0; + } + + return git_default_config(var, value, cb); +} + int cmd_cat_file(int argc, const char **argv, const char *prefix) { int opt = 0, batch = 0; @@ -218,6 +246,8 @@ int cmd_cat_file(int argc, const char **argv, const char *prefix) OPT_SET_INT('e', NULL, &opt, "exit with zero when there's no error", 'e'), OPT_SET_INT('p', NULL, &opt, "pretty-print object's content", 'p'), + OPT_SET_INT(0, "textconv", &opt, + "for blob objects, run textconv on object's content", 'c'), OPT_SET_INT(0, "batch", &batch, "show info and content of objects fed from the standard input", BATCH), @@ -227,7 +257,7 @@ int cmd_cat_file(int argc, const char **argv, const char *prefix) OPT_END() }; - git_config(git_default_config, NULL); + git_config(git_cat_file_config, NULL); if (argc != 3 && argc != 2) usage_with_options(cat_file_usage, options); -- cgit v1.2.3
